They were classified and evaluated according to the CPSI & EPS examinations as analyzed by T test. Results All cases were followed up for an average of 11.8 months(8～18 months).The average CPSI score was 32.6(32.7?5.3) before treatment and 13.4(12.8?7.3) after treatment (P

Objective To establish a clinical diagnostic criterion(referred as criterion hereinafter) for patients with social dysfunction and abnormal mental behaviors caused by internet addiction,so as to provide guidance in future mechanism study,treatment and prevention for such disorder.Methods A rough draft of symptom parameters was used to evaluate the symptoms among the patients with a chief complaint of wallowing in internet which caused damned influence on study,work and interpersonal communication.The 1st draft of the criteria was drawn up according to the incidence and correlation of the symptoms.408 patients with internet addiction(IA) diagnosed according to the 1st draft were followed up for 12 months after being discharged from hospital,and the diagnostic coincidence and recurrence rate were calculated and analyzed,based on which the 1st draft was then revised and the 2nd draft was established.Clinical tests were performed on 150 patients with the same chief complaints by psychiatrists from many mental hospitals in China.Descriptions in the 2nd draft were not modified based on the test findings and the final draft was formulated.Results The proposed criterion for IA symptom included the following 7 items: ① craving for using internet;② withdrawal reactions after internet use reduced or stopped;③ tolerance;④ unable to control the intention of using internet;⑤ regardless of hazardous consequences;⑥ pay no attention to other activities;and ⑦ avoidance or alleviation of unhealthy emotions.Items ① and ② combined with any one of the remains made the final diagnosis of IA.The criterion for illness duration was suggested as greater than or equal to 6 hours of continuous internet use one day in average and 3 months at least after meeting the criteria for IA symptom.It was found by following-up that one year recurrence rate among the discharged patients from hospital was 70.6%,and the diagnostic coincidence was 96.1%.The diagnostic consistency on symptom evaluation between two psychiatric raters was 89.3%-98.0%(Kappa 0.73-0.87,P

Food Sanitation Law which was issued for many years has no longer been congruent with the current development of socio-economy. Under this situation,Food Safety Law came into being. Although the promulgation of the law is important,the task of carrying out the law is more difficult. On the basis of concluding the problems in carrying out the food sanitation law and the analysis of its causes,it is significant to discuss the Food Safety Law from the viewpoint of Food Sanitation Law enforcement.

Methods STK15 expression was detected by immunohistochemical method (ABC) in 54 SCC and 43 GCA patients. Results The positive rate of STK15 in SCC (39% , 21/54) was lower than that in GCA (63 % , 27/43 ), and the difference was significant (P

Objective To investigate the expression of Foxo3a in the lumbar dorsal root ganglia (DRG) after sciatic nerve injury in rats. Methods Forty-two adult rats were randomly divided into control group and experimental group. Rats in experimental group were subjected to sciatic nerve clamp. Expression and distribution of Foxo3a, growth associated protein (CAP) and axon regeneration in DRC were detected by Western blot and immunofluorescent staining. Results (1) After sciatic nerve injury, Foxo3a protein levels began to reduce at day 1, reached the lowest level at day 2 and then gradually rose to nomal level at four weeks after sciatic nerve injury. Proliferating cell nuclear antigen (PCNA) and GAP-43 were up-regulated from day 2, and the level of PCNA reached peak at day 7 after sciatic nerve injury in DRC. (2) Down-regulation of Foxo3a was observed predominantly in neurons and glial cells. PCNA mostly expressed in glial cells and hardly in neurons. Conclusion Down-regulation of Foxo3a in lumbar DRG may correlate with axonal regeneration and the proliferation of glial cells after sciatic nerve injury.

Objective To investigate the expression of Foxo3a and p27kip1 in lumbar dorsal root ganglia (DRG) after injury of sciatic nerve in rats. Methods Adult rats were randomly divided into control group and experimental group. The rats in experimental group were subjected to sciatic nerve clamp.Expression and distribution of Foxo3a and p27kip1 and cellular proliferation and axon regeneration in DRG was detected by western blot and immunohistochemistry. Results Foxo3a protein levels begined to reduce at 1 day (7.0 ± 3.5), reached valley at 2 day (6.0 ± 3.8) after injury, and following Foxo3a downregulation, p27kip1 protein levels begined to decrease at 2 day (29.0 ± 3.5), reached valley at 7 day (21.0± 3.0) after injury. Down-regulation of Foxo3a and p27kip1 was expressed predominantly in neurons and glial cells by double immunolabelling. Foxo3a and p27kip1 were expressed in neurons [(37.8 ± 5.7)%, (43.3 ±4.3)%] and glial [(22.4 ± 3.9)%, (13.8 ± 3.2)%] cells in sections of DRG at 2 day after injury less than neurons [(73.6 ± 2.5)%, (84.1 ± 3.7)%] and glial [(61.3 ± 4.4)%, (68.7 ± 5.6)%] cells in sections of normal DRG. Proliferating cell nuclear antigen (PCNA) and GAP-43 were up-regulation from 2 day, and PCNA reached peak at 7 day after injury.The glial cells were the main type of cellular proliferation.Conclusion Down-regulation of Foxo3a and p27kip1 in lumbar DRG is correlated with the proliferation of glial cells and axonal regeneration after sciatic nerve injury.

Objective To observe the therapeutic effect of rhubarb combined with Probiotics for treatment of patients with severe acute pancreatitis (SAP) accompanied by acute lung injury (ALI). Methods A prospective randomized controlled trial was conducted. Sixty patients with SAP and ALI were randomly divided into a rhubarb group and a combination of rhubarb and Probiotics group (combined group), 30 cases in each group. Both groups were treated with conventional therapy. On that therapeutic base, the patients in rhubarb group were treated with rhubarb 3 g·kg-1·d-1 (Raw rhubarb in boiling water 200 mL was cooked for 30 minutes, then the decoction was divided into two parts to be infused through nasal jejunal tube, retaining for 1 hour);while in the combined group, beside the above rhubarb therapy, the patients were additionally given Probiotics [Clostridium butyric acid:Chang Lekang capsule, once 1 grain (0.42 g), twice a day] through nasal jejunal tube. The therapeutic course was 14 days in the two groups. The plasma endotoxin levels, oxygenation index, and acute physiology and chronic health evaluationⅡ(APACHEⅡ) score were observed before and after treatment for 7 days and 14 days, respectively. After treatment for 30 days, the time of intestine functional recovery and mechanical ventilation, number of damaged organs, number of infectious sites, number of pancreatic pseudocysts, length of intensive care unit (ICU) stay and 30-day fatality rate were observed in the two groups. Results With the prolongation of treatment, the plasma level of endotoxin and APACHEⅡscore in the two groups were gradually reduced, and the oxygenation index was gradually increased after treatment for 7 days and 14 days in the two groups compared with those before treatment, and there were statistically significant differences in above indexes on the 14th day after treatment between combined group and rhubarb group [endotoxin (μg/L): 19.16±1.90 vs. 21.20±1.05, oxygenation index (mmHg, 1 mmHg = 0.133 kPa): 369.50±5.45 vs. 341.50±7.36, APACHE Ⅱscore:11.84±0.60 vs. 13.00±0.86, P<0.05 or P<0.01]. The length of intestine functional recovery in the combined group was longer than that in the rhubarb group (days: 5.63±1.75 vs. 5.02±1.54), the number of damaged organs (2.08±0.74 vs. 2.70±1.11), the number of infectious sites (1.93±0.64 vs. 2.23±0.83), the number of pancreatic pseudocysts (1.22±0.34 vs. 1.63±0.11) and the mortality rate [10.0%(3/30) vs. 13.3%(4/30)] in the combined group were lower than those of the rhubarb group, but there were no statistically significant differences between two groups (all P > 0.05). The times of mechanical ventilation (days: 13.40±1.76 vs. 15.60±1.28) and the length of ICU stay (days:16.13±1.25 vs. 17.63±1.30) were significantly shorter in combined group than those in rhubarb group (both P<0.05). Conclusion Rhubarb combined with Probiotics for treatment of patients with SAP and ALI can promote their recovery of lung function and shorten their length of ICU stay.

Primary rat hepatocytes were cultured using different in vitro models and the enzyme leakage, albumin secretion, and cytochrome P450 1A (CYP 1A) activity were observed. The results showed that the level of LDH was decreased over time in culture. However, on day 5, LDH showed a significant increase in monolayer culture (MC) while after day 8 no LDH was detectable in sandwich culture (SC). The levels of AST and ALT did not change significantly over the investigated time. The CYP 1A activity was gradually decreased in a time-dependent manner in MC and SC. The decline of CYP 1A was faster in MC than in SC. This effect was partially reversed by using cytochrome P450 (CYP450) inducer such as Omeprazol and 3-methylcholanthrene (3-MC) and the CYP 1A induction was always higher in MC than in SC. In bioreactor basic CYP 1A activity was preserved over 2 weeks and the highest albumin production was observed in bioreactor followed by SC and MC. Taken together, it was indicated each investigated model had its advantages and disadvantages. It was also underlined that various in vitro models may address different questions.
