Purpose To evaluate differences in the pattern of optic disc and retinal nerve fiber layer (RNFL) damage in normal-tension glaucoma (NTG) and high-tension glaucoma (HTG) patients. Methods We enrolled 49 eyes of 49 patients:30 NTG (IOP≤21 mm Hg,1 mm Hg=0.133 kPa), 19 HTG(IOP≥25 mm Hg). Mean age was 59.2±12.3 (range, 36-75) for HTG patients, and 59.6±8.6(range, 39-71) for NTG patients. All patients underwent complete ophthalmic examination, achromatic automated perimetry (AAP), scanning laser ophthalmoscopy (SLO), scanning laser polarimetry (SLP), optical coherence tomography (OCT) and Heidelberg retinal tomography (HRT). All patients had glaucomatous optic nerve damage and abnormal AAP. Results There were no differences in mean deviation on AAP between NTG and HTG eyes (P=0.37), while the corrected pattern standard deviation was larger in NTG than in HTG eyes (P=0.014). Cup∶disc area ratios in global (P=0.03) and three sectors (Plt;0.05) except nasal sector were significantly larger in the NTG group, whereas rim area in global (P=0.03) and three sectors (Plt;0.05) except nasal quadrant obtained by SLO were smaller in NTG than in HTG eyes. The other numerical parameters obtained by three imaging technologies could not detect differences in the optic disc or RNFL anatomy between the two groups. Conclusions Cup∶disc area ratio was larger in patients with NTG than in those with HTG, whereas significant thinning of rim was associated with NTG eyes. The measurement of retinal nerve layer thickness in global and each quadrant was similar between two groups. More focal or segmental analysis of the data contained within SLO, SLP and OCT images are needed to detect localized differences in eyes with varying levels of IOP.

To compare the cl inical effect of total hi p arthroplasty (THA) using posterolateral conventional or minimally invasive incision. Methods From January 2007 to November 2007, 38 patients (41 hi ps) were treated with minimally invasive THA (mini-incision group), and 15 patients (15 hi ps) underwent conventional THA (conventional incision group). Mini-incision group: 23 males (25 hi ps) and 15 females (16 hi ps) aged (53.2 ± 15.5) years old; body mass index (BMI) was 23.4 ± 3.3; there were 20 cases (20 hips) of femoral neck fracture, 2 cases (2 hips) of primary osteoarthritis, 14 cases (16 hips) of stage III or IV aseptic necrosis of the femoral head, 2 cases (3 hips) of ankylosing spondyl itis involving hip joint; Harris hip score was 47.7 ± 5.5 and the course of disease was (4.5 ± 4.3) years. Conventional incision group: 7 males (7 hips) and 8 females (8 hips) aged (54.8 ± 10.8) years old; BMI was 26.1 ± 5.1; there were 8 cases (8 hips) of femoralneck fracture, 1 case (1 hip) of primary osteoarthritis, 5 cases (5 hips) of stage III or IV aseptic necrosis of the femoral head, 1 case (1 hip) of ankylosing spondyl itis involving hip joint; Harris hip score was 51.2 ± 4.3 and the course of disease was (3.8 ± 3.7) years. There were no statistically significant differences between two groups in the general information (P gt; 0.05). Results There were statistical differences between two groups in terms of incision length, perioperative blood loss, drainage volume and blood transfusion volume (P lt; 0.05), and no statistical differences were evident in operative time, abduction angle and the anteversion angle of acetabular cup (P gt; 0.05). All incisions healed by first intention and no early postoperative compl ications occurred. Two groups were followed for 12-22 months (average 18.3 months). All patients walked without the crutch at 2-3 months after operation. The Harris score of the mini-incision group and the conventional incision group 6 months after operation was 88.6 ± 3.6 and 85.8 ± 3.3, respectively, indicating there was no significant difference between two groups (P gt; 0.05), but there was significant difference between before and after operation (P lt; 0.05). Conclusion Compared with conventional THA, the minimaly incisive using posteroplateral approach THA has the merits of mini invasion, sl ight hemorrage, short hospital stay, minor compl ication, convenient management of femoral head and accurate prosthesis location. However, strict attention should be paid to operative indications.
Objective To compare effects, advantages and disadvantages of simple internal fixation to that of l imited internal fixation with external supporting frame fixation in the treatment of complex fractures of tibial plateau. Methods From July 2002 to August 2006, 66 cases of complex fractures of the tibial plateau were divided into the internal fixation group (n=39) and the external fixator group (n=27). The interal fixation group had 18 cases of IV, 7 cases V and 14 cases VI according to Schatzker, including 25 males and 14 females aged 18-79 years with an average of 45.4 years. The external fixator group had 13 cases of IV, 6 cases V and 8 cases VI according to Schatzker, including 18 males and 9 femles aged 18-64 years with an average of 44.2 years. No significant difference was evident between the two groups (P gt; 0.05). Patients were treated by using screws, steel plates or external supporting frame fixation strictly based on the princi ple of internalfixation. Results All patients were followed up for 1-5 years. Fracture healed with no occurrence of nonunion. Two cases inthe internal fixation group presented partial skin infection and necrosis, and were cured through the dressing change and flap displacement. Fracture heal ing time was 6-14 months with an average of 7.3 months. The time of internal fixator removal was 6-15 months with an average of 8.3 months. In the external fixation group, 11 cases had nail treated fluid 7 days to 3 months after operation, combining with red local skin; 3 cases had skin necrosis; and 3 cases had loose bolts during follow-up. Through debridement, dressing change and flap displacement, the skin wounds healed. Fracture heal ing time was 3-11 months with an average of 5.1 months. The time of external fixator removal was 5-11 months with an average of 6.4 months. At 8-14 months after operation, the knee function was assessed according to Merchant criteria. In the internal fixation group, 29 cases were excellent, 4 good, 5 fair and 1 poor, while in the external fixation group, 20 cases were excellent, 3 good, 2 fair and 2 poor. There was no significant difference between the two groups (P gt; 0.05). Conclusion The therapeutic effects of simple internal fixation and l imited internal fixation with external supporting frame fixation were similar in the treatment of complex fractures of tibial plateau. Fixation materials should be selected according to the state of injury and bone conditions for the treatment of tibial plateau fracture of type IV, V and VI based on Sehatzker classification.

Objective To evaluate short-term effects of percutaneous microwave coagulation therapy（PMCT） combined with chemotherapy in patients with advanced non-small cell lung cancer（NSCLC）.Methods Eighty cases with advanced NSCLC were randomly assigned to underwent chemotherapy plus PMCT(PMCT group，n=40) or single chemotherapy(chemotherapy group，n=40).The chemotherapeutics regimen was Taxotere plus Cisplatin.The preliminary results and quality of life score of two groups were compared.Results In PMCT group and chemotherapy group，the 3-month relieve rate was 52.5% and 32.5%，and the half-year survival rate was 87.5% and 62.5%，respectively.The differences between the two groups were both significant(Plt;0.05).The quality of life score in PMCT group was significantly higher than that in chemotherapy group (Plt;0.05).Conclusion PMCT combined with chemotherapy is effective and safe in the treatment of advanced NSCLC.
ObjectiveTo discuss the relationship between antinuclear antibody (ANA) fluorescence pattern detected by indirect immunity fluorescence (IIF) and antinuclear antibody profiles (including anti-dsDNA, RNP, Sm, SSa, SSb, Scl-70, Jo-1 and rib-P) in human serum. MethodsA total of 7385 cases of ANA pattern and ANA profiles were retrospectively analyzed from January 2010 to December 2013. ANA was detected by IIF substrated as HEp-2 cells, anti-dsDNA by IIF substrated as crithidia, and the other 7 antibodies by enzyme immunoblot with purified antigen. ResultsGranular pattern mostly presented as anti-RNP, anti-Sm, anti-SSa and anti-SSb (P < 0.001); homogeneous pattern was anti-dsDNA and anti-SSa (P < 0.001); nucleolus, centromere, and mixed pattern was anti-SSa (P < 0.05); cytoplasm pattern was anti-rib-P and anti-SSa (P < 0.05). But few above antibodies could be detected in Golgi, dots, rim, actin, actotropomyosin, prolifevating cell nuclear antigen (PCNA) and vementin pattern. Homogeneous pattern was shown up to 77.91% in only anti-dsDNA positive serum; granular was 96.84%, 52.01%, and 82.35% respectively in only anti-RNP or anti-SSa or anti-Sm positive. Homogeneous and nucleolus mix pattern was up to 30.53% in only anti-Scl-70 positive. Cytoplasm pattern was 50.00% and 61.54% respectively in only anti-rib-P or anti-Jo-1 positive. But no fixed relationship was found between ANA pattern and anti-SSb. ConclusionsThere is a certain relationship between ANA and antinuclear antibody profiles. Granular, homogeneous and cytoplasm pattern often can be detected more than one autoantibodies. Eight kinds of specific autoantibodies often are negative when ANA patterns are centromere, Golgi, dots, rim, actin, tropomyosin, PCNA, and vimentin. Anti-dsDNA is mainly corresponding to homogeneous, anti-RNP, anti-SSa and anti-Sm to granular, anti-Scl-70 to homogeneous and nucleoli, anti-rib-P and anti-Jo-1 to cytoplasm. The study can give suggestions for further tests application and lab result checking.
To discuss the advantages of two flap contouring methods and to explore the best choice for the flap contouring. Methods From March 2002 to March 2006, 59 patients were admitted for a flapcontouring operation. Of the 59 patients, 40 (32 males, 8 females; average age, 34 years) underwent the multiphase lipectomy (the multiphase lipectomy group). The original flaps included the abdominal flap in 19 patients, the groin flap in 10, the thoracic flap in 4, the free anteriolateral thigh flap in 6, and the cross leg flap in 1. The flaps ranged in size from 6cm×4 cm to 32 cm×17 cm. However, the remaining 19 patients (16 males, 3 females; average age, 28 years) underwent the onephase lipectomy with skin graft transplantation(the onephase lipectomy group). The original flaps included the abdominal flap in 4 patients, the groin flap in 6, the thoracic flap in 3, and the free anteriolateral thighflap in 6. The flaps ranged in size from 4 cm×3 cm to 17 cm×8 cm. The resultswere analyzed and compared. Results In the multiphase lipectomy group, partial flap necrosis developed in 4 patients but the other flaps survived. The followedup of 27 patients for 3 months to 2 years revealed that the flaps had a good appearance and texture, having no adhesion with the deep tissues. However, the flaps became fattened in 22 patients with their body weight gaining. The patietns who had a flap gt; 5 cm×5 cm in area had their sensation functions recovering more slowly; only part of the sensations to pain and heat recovered. The two point discrimination did not recover. In the onephase lipectomy group, total graft necrosis developed in 1 patient but the healing was achieved with additional skin graft transplantation; partial graft necrosis developed in 2patients but the wounds were healed after the dressing changes; the remaining flaps survived completely. The followup of the 16 patients for 3 months to 3 years revealed that all the 16 patients had a good sensation recovery, 12 patientshad the two point discrimination lt; 15 mm, with no recurrence of the fattening of the flaps; however, the grafted skin had a more severe pigmentation, and no sliding movement developed between the skin and the tissue basement. Conclusion The multiphase lipectomy and the onephase lipectomy with skin graft transplantation are two skin flap contouring methods, which have their ownadvantages and disadvantages. Which method is taken should be based on the repair location of the 〖WT5”BZ〗skin flap and the condition of the skin flap.
Objective To compare the outcomes and safety of 23G and 20G vitrectomy for treatment of infectious endophthalmitis. Methods This was a retrospective case study. Sixtyseven eyes of 67 eyes suffering from infectious endophthalmitis with a history of trauma or intraocular operation history were enrolled in this study. They were diagnosed by the examinations of best corrected visual acuity, intraocular pressures, slit lamp microscope, indirect ophthalmoscopy, B-scan ultrasound and CT. There were 49 males (49 eyes) and 18 females (18 eyes). The patients aged from 18 to 72 years with a mean age of (43plusmn;13) years. There were 60 patients (60 eyes) with a history of trauma, 7 patients (7 eyes) with intraocular operation history. The patients were enrolled into 20G vitrectomy group (35 patients, 35 eyes) before December, 2009 and 23G vitrectomy group (32 patients, 32 eyes) after January, 2010 when 23G vitrectomy system was imported in this hospital. Vitreous purulence was taken in all patients at the beginning of the surgery for bacteria and fungal culture and drug sensitivity test. A standard vitrectomy with artificial posterior vitreous detachment followed by internal limiting membrane peeling, and (or) intraocular laser photocoagulation, cryocoagulation, fluidair exchange with intraocular silicone oil or gas tamponade were performed in all cases. Broadspectrum antibiotics and glucocorticoids were used systematically for one week after surgery, but glucocorticoids were not used for fungal infections. The followup was ranged from two to nine months with a mean of (7plusmn;1) months. The surgical time, inflammation situation, visual acuity, intraocular pressure, retinal reattachment rate, iatrogenic retinal hole rate, bulbar conjunctiva scar formation rate, reoperation rate and eye retention situation before and after surgery were comparatively analyzed. Results The mean surgical times were (126plusmn;12) and (89plusmn;12) minutes in 20G and 23G group, which was significantly different (t=3.125, P＜0.05). The major surgery complications were ora serrata dialysis and other iatrogenic retinal breaks, and were occurred in 34 eyes, including 30 eyes (85.71%) in 20G group and 4 eyes (12.50%) in 23G group (chi;2=35.85,P＜0.05). These 4 eyes in 23G group received foreign body removal surgery previously. The inflammation was controlled in 65 eyes (97.01%) including 34 eyes (97.14%) and 31 eyes (96.88%) in 20G and 23G group respectively, which was not significantly different (chi;2=0.004,P＞0.05). At last follow-up, There was no statistical difference of visual acuity between the two groups (t=3.12, P＞0.05). Fourteen eyes underwent silicone oil tamponade including 13 eyes (37.14%) and 1 eye (3.13%) in 20G and 23G group respectively, which was significantly different (chi;2=11.703, P＜0.05). Nine eyes underwent reoperation (13.43%), including 8 eyes (22.86%) and 1 eye (3.13%) in 20G and 23G group respectively, which was significantly different (chi;2=5.597,P＜0.05). The 8 re-operated eyes in 20G group included 1 eye of recurrent endophthalmitis and 7 eyes with retinal detachment, the 1 re-operated eye in 23G group was of recurrent endophthalmitis. There was significantly different (chi;2=7.147,P＜0.05) for the rate of retinal detachment between the 2 groups. There were 40 eyes with bulbar conjunctiva scar including 35 eyes (100.00%) and five eyes (15.63%) in 20G and 23G group. Conclusion 23G vitrectomy is an effective treatment for infectious endophthalmitis with shorter surgery time, lower reoperation rate, lower retinal reattachment rate and fewer bulbar conjunctiva scar.
Objective To evaluate the application of tendency-oriented perimetry (TOP) in detecting the visual function of glaucoma. Methods The traditional threshold perimetry (Normal/Normal strategy) and TOP (TOP/Normal strategy) carried out by Octopus 101 perimetry were used to examine the visual field of 20 normal subjects (20 eyes), 32 cases (32 eyes) of primary open-angle glaucoma (POAG), and 14 cases (14 eyes) of suspected POAG, respectively. The visual field outcomes, indices, point by point threshold variability and defective points of the two perimetries were compared and analysed. Results The negative rate of TOP was 90% in normal subjects. The positive rate of TOP was 75% in POAG , and 100% in middle and late stage of POAG. The visual field indices of two perimetries were positively correlated, with mean sensitivity (MS) of r=0.9335, mean defect (MD) of r=0.9189, and loss variance (LV) of r=0.9621. The point by point threshold variability and defective points of TOP were higher than those of traditional threshold perimetry, but the difference between the two perimetries was not significant (P=0.2019, P=0.4448). Conclusion The visual field indices of TOP and traditional threshold perimetry are positively correlated. The sensitivity and reproducibility of TOP are high in detecting the visual function of middle and late stage of POAG. (Chin J Ocul Fundus,Dis, 2002, 18: 269-272)
