Penicillin is a kind ofβ-lactam drug which has been applied in the clinical treatment firstly in the world, and it has still been widely used at present. The synthesis and regulation mechanism of Penicillium chrysogenum, which is used to produce penicillin, has been studied quite maturely, but its proteomics research started relatively late and fewer reports were published. This paper reviews the synthesis and application of penicillin, transformation of Penicillium chrysogenum, and the research progress of its proteomics. On this basis, the study highlights the advantages of proteomics in the research of protein expression.
Objective To evaluate the effect of ultrasound guided percutaneous drainage on acute perforation of gastroduodenal ulcer in elderly patients. Methods The clinical features, treatments, and the curative effects of 86 elderly cases (≥65 years) of acute perforation of gastroduodenal ulcer in our hospital between January 2004 and October 2009 were retrospectively analyzed. Twenty-one cases were treated by ultrasound guided percutaneous drainage (drainage group), and 65 cases were treated by exploring operation (operation group). Results Drainage group was cured and had no complications. In 15 patients which accepted recheck one month after drainage, gastroscope showed the ulcer healed in 12 cases， and improved in 3 cases. In operation group, 63 cases were cured and 2 cases died. Compared with the drainage group, there was no significant difference in cure rate (Pgt;0.05). However, 11 patients had operative complications in operation group, which was significantly more than that in the drainage group （Plt;0.05）. In 45 patients which accepted recheck one month after operation, gastroscope showed the ulcer healed in 38 cases， and improved in 7 cases. Conclusion For elderly patients with acute perforation of gastroduodenal ulcer， if the patients do not fit for exploring operation， ultrasound guided percutaneous drainage is proved to be a simple, safe, and effective means.
目的 报告螺纹管在左半结肠梗阻造瘘术中的应用以及术后护理的体会。方法 对近年来收治的36例左半结肠癌性梗阻患者行急诊梗阻近端结肠螺纹管造瘘，并与同期施行的20例结肠造瘘一期外翻成形做比较。结果 结肠螺纹管单腔造瘘术操作简单，术后患者获得满意的减压效果，未发生切口感染。而一期外翻成形者有3例发生切口感染。结论 左半结肠梗阻术中行螺纹管造瘘是一种简单、经济、省时、低污染、减压效果好、护理方便的手术方法。
ObjectiveTo evaluate the curative effect of laparoscopic assisted and open D2 radical resection in treatment of advanced gastric cancer. MethodsThe clinical data of 76 cases performed by laparoscopic assisted D2 radical resection (laparoscopic group) and 104 cases performed by open operation (open group) from October 2010 to October 2012 in our center were retrospective analized.Operation related index, postoperative recovery, and extent of radical resection of tumor of 2 groups were compared. ResultsThe operative time of the laparoscopic group[(192.5±14.8) min]was longer than that open group[(171.5±16.5) min, P < 0.05].But the blood loss, postoperative drainage, length of incision, and hospital stay of the laparoscopic group were significantly less or shorter than those of open group (P < 0.05).There were no significant difference in postoperative complications and extent of radical resection of tumor between the 2 groups (P > 0.05).There were no residual tumor in distal margin and operatiive death case in both 2 groups. ConclusionComparing with open operation, the laparoscopic assisted surgery for advanced gastric cancer could achieve the same clinical outcomes, and obvious advantage of minimal invasion.
ObjectiveTo explore the early diagnosis and treatment of acute non-tumor perforation of the back wall of ascending colon. MethodsWe retrospectively analyzed the clinical data of 17 patients with acute non-tumor perforation of the back wall of ascending colon treated between July 2007 and April 2014 in our hospital. Among them, 8 patients who underwent perforation repair combined with abdominal cavity drainage were regarded as the experimental group, and the other 9 patients who underwent operation of right hemicolectomy (or ascending colon resection) were designated as the control group. Clinical indexes and biochemical indexes of both the two groups were compared and analyzed. ResultsAll patients were cured. The operation time[(74.20±12.45), (120.23±15.20) minutes; t=-3.224, P<0.001], the intraoperative blood loss[(40.24±12.20), (80.69±18.98) mL; t=-4.114, P<0.001], the postoperative anal exhaust[(75.62±6.56), (84.54±7.82) hours; t=1.108, P=0.037], the medical expenses[(18.2±5.7) thousand yuan, (26.5±8.3) thousand yuan; t=-5.556, P<0.001], and the hypersensitive C-reaction protein on the third day after operation[(89.45±8.98), (99.85±10.78) mg/L; t=-3.004, P=0.029] in the experimental group and the control group all had significant differences. There was no significant difference between the two groups in the hospital stay time[(9.80±3.16), (9.81±3.20) days; t=1.501, P=0.080]. There was one case of incision infection in the experimental group and one case of fat liquefaction of incision in the control group, and both of them were cured after treatment. ConclusionThe early abdominal sign of perforation of the back wall of ascending colon is not obvious, which can easily lead to misdiagnosis as acute appendicitis. Early diagnosis mainly depends on the clinical symptom, vital sign, blood routine examination and CT examination. Among them, CT findings of gaseous sign behind peritoneum is a definite diagnosis, and operation should be arranged as early as possible. Perforation repair combined with abdominal cavity drainage is preferred due to its advantages of being simple, saving time, less bleeding and lighter traumatic reaction.
