ObjectiveTo explore the influence of sentinel lymph node (SLN) status on the prognosis of elderly breast cancer patients ≥70 years old, and to screen patients who may be exempted from sentinel lymph node biopsy (SLNB), so as to guide clinical individualized treatment for such patients. MethodsA retrospective analysis was made on 270 breast cancer patients aged ≥70 years old who underwent SLNB in the Affiliated Hospital of Southwest Medical University from 2012 to 2021. The clinicopathological characteristics of the total cases were compared according to the status of SLN. Kaplan-Meier method was used to draw the survival curve, and the influence of SLN status on the overall survival (OS) time, local recurrence (LR) and distant metastasis (DM) of patients were analyzed, and used log-rank to compare between groups. At the same time, the patients with hormone receptor (HR) positive were analyzed by subgroup. The differences between groups were compared by single factor χ2 test, and multivariate Cox regression model was used to analyze and determine the factors affecting OS, LR and DM of patients. ResultsThe age of 270 patients ranged from 70 to 95 years, with a median age of 74 years. One hundred and sixty-nine (62.6%) patients’ tumor were T2 stage. Invasive ductal carcinoma accounted for 83.0%, histological gradeⅡ accounted for 74.4%, estrogen receptor positive accounted for 78.1%, progesterone receptor positive accounted for 71.9%, and human epidermal growth factor receptor 2 negative accounted for 83.3%. The number of SLNs obtained by SLNB were 1-9, and the median was 3. SLN was negative in 202 cases (74.8%) and positive in 68 cases (25.2%). Thirty-five patients (13.0%) received axillary lymph node dissection. There was no significant difference in LR between the SLN positive group and the SLN negative group (P>0.05), but the SLN negative group had fewer occurrences of DM (P=0.001) and longer OS time (P=0.009) compared to the SLN positive group. The results of univariate and multivariate analysis suggest that the older the patient, the shorter the OS time and the greater the risk of DM. Analysis of HR positive subgroups showed that SLN status did not affect patient survival and prognosis, but age was still associated with poor OS time and DM. ConclusionsFor patients with invasive ductal carcinoma of breast in T1-T2 stage, HR positive, clinical axillary lymph nodes negative, and age ≥70 years old, SLNB may be exempted. According to the patient’s performance or tumor biological characteristics, patients who need systemic adjuvant chemotherapy may still consider SLNB.
ObjectiveTo explore the epidemiological characteristics and analyze the related diagnosis and treatment information of wound outpatient cases in a tertiay hospital in Leshan City.MethodsThe data of cases admitted to the wound clinic in a tertiary hospital of Leshan City between January 1st, 2017 and December 31st, 2019 were retrospectively collected. The SPSS software was used for statistical analyses in terms of basic patient information, wound type and dressing use, number of visits and expenses.ResultsA total of 10 880 cases were enrolled. The average age of the patients treated was (45.23±13.45) years old. Patients from the Central District, where the hospital was located in, accounted for the highest proportion (38.63%). The proportion of acute skin and soft tissue injuries was higher than that of chronic skin and soft tissue injuries (62.51% vs. 37.49%). According to the proportions from high to low, the top three chronic skin and soft tissue injuries were postoperative refractory wounds (19.63%), skin and soft tissue infections (3.90%), and stoma complications (3.04%), respectively. A total of 22 937 functional wound dressings were used, of which non-woven outer dressings accounted for 47.52%. Patients with acute skin and soft tissue injuries had a higher healing rate compared with those with chronic skin and soft tissue injuries (96.65% vs. 43.03%, P<0.05). The type of skin and soft tissue injuries with the most visits was cancerous wound [the median (lower quartile, upper quartile) was 68 (35, 121) visits], and the one with the least visits was acute skin and soft tissue injuries [the median (lower quartile, upper quartile) was 2 (1, 7) visits].ConclusionsAs the distance between residence and hospital grows, the number of patients decreases, suggesting that the specialized nursing assistance has achieved initial results in remote areas, but the task of assistance in surrounding areas is still heavy. The type of skin and soft tissue injuries is changing under the concept of enhanced recovery after surgery, and wound care plays an important role in the recovery of patients after surgery. The concept of wet healing and new dressings to promote wound healing are widely used, but still need to be further popularized among patients and medical staff. For chronic wounds that are more expensive to treat, it is necessary to formulate comprehensive treatment plans such as wound treatment, psychological support, and systemic nutrition to promote healing.
Objective To investigate the clinical features, diagnosis, and surgical methods of left-sided appendicitis (LSA). Methods We retrieved LSA-related literatures through Pubmed, Google Scholar English databases, Wanfang, CNKI, VIP, and SinoMed databases (published from January 1981 to June 2017), as well as 2 cases of LSA who treated in Beibei Traditional Chinese Medical Hospital, to analyze the clinical characteristics of LSA and its diagnosis and treatment methods. Results There were 92 articles in a total of 212 LSA patients were retrieved, and 2 cases treated in Beibei Traditional Chinese Medical Hospital, a total of 214 LSA patients were included in the analysis. Pain fixed position of LSA: 139 cases (65.0%) located in left-lower quadrant, 30 cases (14.0%) located in right-lower quadrant, 8 cases (3.7%) located in peri-umbilical, 15 cases (7.0%) located in mid-lower abdomen, 15 cases (7.0%) located in left-upper quadrant, 3 cases (1.4%) located in right-upper abdomen, 2 cases (0.9%) located in mid-upper abdomen, 2 cases (0.9%) located in pelvic cavity, respectively. LSA had occurred in association with several types of abnormal anomalies: 131 cases (61.2%) suffered from situs inversus totalis (SIT), 53 cases (24.8%) suffered from midgut malrotation (MM), 21 cases (9.8%) suffered from cecal malrotation, 4 cases (1.9%) suffered from long appendix, 2 cases (0.9%) suffered from free ascending colon, and 3 cases (1.4%) were unclear. The diagnosis of 114 LSA cases (53.3%) before operation was correct, in which the correct diagnosis rates of SIT-LSA and MM-LSA were 74.8% (98/131) and 22.6% (12/53), respectively. Three patients (1.4%) underwent conservative treatment, and 211 patients (98.6%) underwent surgical treatment, including 25 cases (11.7%) of laparoscopic surgery, 145 cases (67.8%) of open abdominal surgery, and unknown of 41 cases (19.1%). Laparotomy incision: abdominal incision in 74 cases (51.0%), ventral midline incision in 16 cases (11.0%), the left side of the anti McBurney incision in 43 cases (29.7%), right McBurney incision in 12 cases (8.3%). Conclusions LSA mainly occurs in association with 2 types of congenital anomalies: SIT and MM. There is some difficult to make diagnosis for abnormal anatomy and inaccurate pain location of LSA, so it is easy to cause the delay in diagnosis or misdiagnosis. For LSA, the choices of laparoscopy or laparotomy operation methods are applicable.
ObjectivesTo analyze the average daily medical expenditures for primary liver cancer in China from 2002 to 2011.MethodsThis study employed retrospective survey on multiple centers from 12 provinces and cities in China from 2002 to 2011, based on the continuous data from the Cancer Screening Program in the Urban China Project. The average daily medical expenditures of primary liver cancer patients and influencing factors were analyzed.ResultsA total of 11 045 liver cancer patients from 12 provinces and cities were included, with an average age of 55 and an average duration of hospitalization of 16.76 days. The average daily medical expenditures of liver cancer patients during the 10 years was 1 251 yuan (95%CI 1 236 to 1 266). The average daily medical expenditures was significantly different in regions (1 356 yuan in the east region, 1 209 yuan in the middle region and 1 068 yuan in the west region), types of hospital (1 341 yuan in general hospitals, 1 213 yuan in specialized hospitals) and hospital levels (1 293 yuan in 3A grade hospital, 805 yuan in non-3A grade hospital) (P<0.05). The average daily medical expenditures were 1 253 yuan for stage Ⅰ, 1 169 yuan for stage Ⅱ, 1 167 yuan for stageⅢ and 1 092 yuan for stage Ⅳ (P<0.05). From 2002 to 2011, the average daily medical expenditures of hospitalization increased from 1 079 yuan (95%CI 1 021 to 1 136) to 1 549 yuan (95%CI 1 486 to 1 613), with an average growth rate of 3.69%. Since 2007, a continuous growth was observed. Subgroup analysis suggested there were obvious differences in growth patterns between different regions and hospitals, as well as differences between various treatments.ConclusionsThe average daily medical expenditures of liver cancer in China had been increasing from 2002 to 2011 and there were significant differences between various regions and hospital levels. Combined with data on the change of duration of hospitalization, it can provide reference for the economic evaluation of the nation’s prevention and treatment policies for liver cancer.
OBJECTIVE: To investigate the therapeutic effect of flap transplantation in repairing soft tissue defects of children. METHODS: From January 1997 to May 2002, 75 cases of different soft tissue defects (52 males and 23 females, with the age of 3-14 years) were repaired by axial and non-axial flaps transfer, and axial flaps transplantation by microvascular anastomosis. The flaps area ranged from 3 cm x 5 cm to 15 cm x 42 cm. Emergency operation was performed in 26 cases and secondary operation in 49 cases (infective wound such as osteomyelitis and plate extra-exposed of fracture). The defect regions included the forearm, back of the hand, thumb, index finger, leg and foot. The types of flap graft and application range included 39 cases of axial flaps transfer or transplantation (27 cases of along- or contra-transfer of transplantation and 12 cases of microvascular anastomosis). The non-axial flaps transfer were designed along- or contra-transfer near the wound area in 36 cases. The ratio of length to width was 2.5:1-3.5:1 in 27 cases, and larger than 3.5:1 in 9 cases. Adequate anesthesia method should be chosen according to the characteristics of children, non-traumatic operating during surgery and postoperative supervision and nursing of flaps should also be paid enough attention. RESULTS: After operation, blood circulation crisis occurred in 2 cases (1 case of artery failure and 1 case of vein failure). The flaps survived in 37 cases and partially survived in 1 case and necrosed in 1 case. The survival rate was 96.2%. The postoperative follow-up period was 3 to 60 months, the blood supply, elasticity and texture of flaps were good. The effect of repair was satisfactory. CONCLUSION: Different types of transplantation of blood-supply of flaps may repair the different types of soft tissue defects in children. Free flap transplantation is safe and beneficial in children, different defects of soft tissue were repaired by axial and non-axial flaps transfer, axial flaps transplantation by microvascular anastomosis. Non-traumatic operating and postoperative supervision and nursing of flaps should also be paid enough attention.
Objective To improve the knowledge of epidemiology, diagnosis and treatment of aspirin induced asthma ( AIA) in China. Methods Thirty-six cases with AIA who were reported in 30 papers in recent 10 years were analyzed retrospectively. Results The drugs which induced AIA in China mainly included acetylsalicylic acid ( aspirin) , ibuprofen ( Fenbid, ibuprofen) , while acetaminophen ( paracetamol,Bufferin, Tylenol ) , phenylpropanoid thiazide ( Piroxicam) , methoxy-naphthalene C acid ( naproxen) ,diclofenac in rare cases. 28. 6% ( 8 /28) of AIA patients were complicated with nasal disease . AIA could occur at all ages, especially for those over 40 years ( 72. 2% , 26 /36) . No significant difference of prevalencein male and female. The onset time of AIA was less than 60min in 71. 4% and gt;120min in 38. 6% . Most patients took the medications by oral ( 83. 3% ,30/36) , but the AIA onset time was not different by different administration route. Conclusions The incidence of AIA increases in recent years because of widely use of NSAIDs. However, no awareness of NSAIDs induced asthma is common in patients and physicians. For asthma patients it must be caution to take antipyretic analgesic anti-inflammatory drugs. If necessary,methoxy-naphthalene C acid ( naproxen) and diclofenac could be better choice.
ObjectiveTo sort out the historical evolution of diagnostic screening methods for pancreatic cancer, and to explore how to achieve early diagnosis and treatment of pancreatic cancer in the context of China’s large population base and economic development.MethodsSystematic review was performed. The computer was used to search databases inchuding CNKI, VIP, WanFang Data, Web of Science, PubMed and EMbase. Two researchers independently searched Baidu search engine to collect relevant reports on screening methods and effect evaluation of pancreatic cancer published before February 28, 2018, and a qualitative descroption was made.ResultsA total of 117 articles were included in the study. The exploration of screening methods for pancreatic cancer in China has experienced three stages: germination, enlightenment and growth. Current screening methods include clinical manifestations, imaging screening methods, serum tumor markers and molecular biology gene diagnosis, each of which had its advantages and disadvantages. Single method could not achieve higher specificity and sensitivity, and joint detection had become an inevitable trend. Considering the benefit of practical application, screening among high-risk groups could effectively reduce the population size and achieve accurate screening.ConclusionThere was a big gap between domestic and foreign research in screening for pancreatic cancer. Screening methods are diverse, and joint detection is an inevitable trend. Screening for pancreatic cancer in high-risk population will become a breakthrough under the technical bottleneck.

Objective To investigate the risk factors of infantile urolithiasis resulted from taking milk powder with melamine. Methods The clinical data of infant and young children who took free-screening for melamine associated urolithiasis in the Lanzhou University Second Hospital from September 14th, 2008 to January 6th, 2009 were collected, while the infants without urolithiasis in the same number as those with urolithiasis were also randomly collected into the control group. Then both univariate and multivariate analyses were performed with a logistic regression model to assess the independent risk factors for urolithiasis. Results Of the screened children, 647 children were included in the urolithiasis group and 647 were in the control group. There were 678 boys and 616 girls with an average age of 19.27 months. The results of logistic regression analysis showed that, the children fed with Sanlu powdered infant milk formula which contained a high level of melamine were more likely to suffer from urolithiasis than those took other melamine-contaminated formula (OR=6.09, Plt;0.01); boys were more than girls (OR=1.39, Plt;0.01), and children fed with formula alone were more than those fed with both formula and breast milk (OR=1.61, Plt;0.01). The risk of urolithiasis decreased gradually with age, and the OR value of children in age of smaller than 6 months, 6 to 12 months, 12 to 24 months were 5.23 (Plt;0.01), 2.73 (Plt;0.01), and 1.60 (Plt;0.01), respectively. The risk of urolithiasis increased gradually with the time lengthening of taking melamine-contaminated formula, and the OR value of children who had took melamine-contaminated formula for 3 to 6 months, 6 to 12 months and more than or equal to 12 months were 2.10 (Plt;0.01), 2.81 (Plt;0.01), and 4.75 (Plt;0.01), respectively. Conclusion It shows that feeding with high melamine infant formula (Sanlu powdered infant milk formula), artificial feeding and male children are the risk factors of infantile urolithiasis. Additionally, the risk of urolithiasis decreases with age and increases with time of formula feeding
