As the active ingredient of traditional Chinese medicine Scutellaria baicalensis Georgi, baicalin has a variety of pharma-cological effects. In recent years, baicalin has made significant achievement in the prevention and treatment of central nervous system diseases, such as ischemic brain injury, hemorrhagic brain injury, Parkinson' s disease and spinal cord injury. Numerous studies showed that baicalin could prevent oxygen free radical injury, inhibit nerve cell apoptosis, inhibit inflammation factor expression, pro-tect the mitochondrial energy metabolism, inhibit thrombin receptor and adjust the balance of excitatory amino acid and inhibitory amino acid. Based on the neuroprotective effect of baicalin, it may be a potential medicine for the treatment of central nervous system disea-ses.

In recent years, the medical graduates who take part in postgraduate examination have been increasing each year. The preparation for postgraduate examination affects the clinical practice, but not yet has a quantitative report. This article studied the students in general surgery, which were divided into postgraduate examination group and clinical practice group. By comparing the theoretical knowledge results and the clinical practice skills between the two groups we found that there was no difference between the two groups in the theoretical and operating skill when they were just in the department, and the operating results in the clinical practice group were better than the postgraduate examination group when they were out of the department.

Advanced gastric cancer is usually dealt with D2 radical dissection. There are different opinions as to whether it is necessary to perform D3 radical lymphadenectomy.Some scholars thought that properly enlarged radical dissection can improve long-term outcomes for the treatment of advanced gastric cancer.In recent years,laparoscopic D1 and D2 radical dissection of gastric cancer could be carried out in many hospitals.However,the technique and related skills for performing D3 radical lymphadeneetomy through laparoscope remains to be explored.Based on our previous experiences,D3 radical lymphadeneetomy using artery suspension method and medial-to-lateral approach for advanced gastric cancer is proved to be safe and feasihle.

Objective To investigate the predictive factors of progressive motor deficits (PMD) after isolated pontine infarction. Methods Consecutive patients with isolated pontine infarction admitted to hospital within 48 hours after onset were enroled. They were divided into either a PMD group (increase ≥1 within 7 days) or a non-PMD group according to the clinical course and the changes of motor scores of the National Institutes of Health Stroke Scale (NIHSS). The pontine infarction patterns were classified as basal surface infarction and deep infarction, the sides were divided into left and right, the infarct levels were divided into upper, middle, and lower according to diffusion-weighted imaging. The demographics, baseline clinical data, and imaging features were compared between the two groups. Multivariable logistic regression models were used to analyze the predictive factors of PMD after isolated pontine infarction. Results A total of 101 patients with isolated pontine infarction admitted to hospital within 48 h of onset were enroled, including 16 in the PMD group and 85 in the non-PMD group. The proportions of pontine infarction involving the basal surface (87. 5% vs. 47. 1% , χ2 = 8. 851, P = 0. 003), the infarcts on the middle levels (56. 2% vs. 24. 7% , χ2 = 4. 851, P = 0. 028), and basilar artery stenosis or occlusion (62. 5% vs. 27. 1% ,χ2 = 7. 689, P = 0. 006) of the PMD group were significantly higher than those of the non-PMD group, while the proportions of the infarcts on the left sides (18. 8% vs. 56. 5% , χ2 = 7. 664, P = 0. 006) and the infarcts on the upper levels (37. 5% vs. 72. 9% , χ2 = 7. 689, P = 0. 006) of the PMD group was significantly lower than those of the non-PMD group. Multivariate logistic regression analysis identified that pontine infarction involving the basal surface (odds ratio 5. 650, 95% confidence interval 1. 011 - 31. 580, P = 0. 049) and basilar artery stenosis or occlusion (odds ratio 4. 075, 95% confidence interval 1. 127 - 14. 741, P = 0. 032) were the independent risk factors for PMD after isolated pontine infarction. Conclusions Infarction involving the basal surface and basilar artery stenosis or occlusion may be the predictors for PMD after isolated pontine infarction.

ObjectiveTo evaluate the feasibility, safety and the long-termoutcomes of laparoscopy-assisted distal gastrectomy (LADG) for advanced gastric cancer (AGC).MethodsWe retrospectively analyzed the clinical and follow-up data of 346 cases after LADG from January 2004 to June 2009, compared with 313 cases after conventional open distal gastrectomy (ODG) for advanced gastric cancer at the same period at our hospital. The surgical safety, postoperative complications, survival rate, and the recurrence and metastasis of cancer were compared.ResultsThere was no significant difference at the average time of LADG and ODG procedures (211 ± 56) min vs.(204 ±41 ) min, but blood loss during operation and length of incision in LADG group were significantly less than in the ODG group. The proximal and distal length were, respectively, (6. 3 ± 2. 0) cm and (5. 7 ± 1.7 ) cm in LADG group and (6. 3 ±2. 1 ) cm and (5.6 ± 1.6) cm in ODG group, the difference was not significant. The number of lymph node dissections was also similar: (33 ± 13) in LADG group and (33 ± 16) in ODG group. The incidence of postoperative complications in LADG group was significantly lower than that in ODG group ( 6. 7% vs.13. 1%, P < 0. 05). During the follow-up period of 6-72 months (average 37 months), the 1-, 3-and 5-year survival rates were, respectively, 87. 2%, 57. 2% and 50. 3% in LADG group and 87. 1%, 54. 1%and 49. 2% in ODG group, the difference was not significant. The differences in recurrence and metastasis between the two groups were not statistically significant.ConclsionLaparoscopy-assisted gastrectomy for advanced gastric cancer is not significantly different with open surgery in postoperative survival rate or recurrence. It is less traumatic and of fewer complications.
