OBJECTIVE To explore a management method for the prevention and control of infectious diseases in hospital. METHODS We applied the PDCA (plan,do,check and action) model to establish a management strategy for the prevention and control of infectious diseases for three years. The components of the management model included providing educational program for medical staff,designing and realizing direct network system for infectious disease reporting,monitoring diagnosed infectious diseases ,analyzing their epidemic tendency,guiding medical staff to prevent and control infectious diseases,and strengthening the surveillance,feedback,rewards and punishment. RESULTS The rate of delayed or missed report of infectious diseases was decreased from 5% to 1.1% by monthly check and from 6.8% to 0% by seasonally cross check. Although 46 cases of AIDS,5 cases of caesarean birth with HIV possitive and 1445 cases of hand-foot-mouth disease were admitted in our hospital,No medical staff and other patients was crossly infected. CONCLUSIONS Our way of management based on PDCA model can strengthen the prevention and control of infectious diseases and assure medical quality and patient safety.

OBJECTIVE To study the distribution and drug resistance of nosocomial infection(NI) pathogens.METHODS The NI pathogens collected between Jan 2002 and Dec 2008 were completely surveyed and analyzed.RESULTS Totally,9518 samples were cultured to find NI pathogens,in which 6703 NI pathogens were isolated.In the pathogens,G-pathogens occupied 59.5%,G+ cocci 25.0%,and fungi 15.5%.The rate of ESBLs in E.coli was reached to 47.8%,and that in K.pneumoniae was 29.4%;The first two predominant G+ pathogens were Staphylococcus aureus(11.7%) and Enterococcus(5.7%).The rate of MRSA in S.aureus was 78.2%,and that of VRE in Enterococcus was 2.3%,The pathogens of fungus were mainly Candida albicans(10.2%).CONCLUSIONS The G-NI pathogens are markedly increased year by year and become the first important instead of G+ cocci,meanwhile the multiple drug resistance and ESBLs pathogens are also markedly increased.

Objective:To evaluate the changes of neurocognitive function in early stage in patients with first-episode schizophrenia.Methods:In this study,73 cases of patients with first-episode schizophrenia (research group) and 75 cases of health person (control group) were selected from January 2015 to January 2016 in our hospital.The neurocognitive function was evaluated by neuro-psychological testing tool and the data between two group were compared.Results:Scores of delayed recall,total recall,3 trial,2 trial and 1 trial of research group were lower than those of control group in BVMT-R test,and the difference was statistically significant (P＜0.05).In HVLT-R test,the scores of total delay,3 trial and 2 trial of research group were significantly lower than those of control group (P＜0.05).The consuming time of dominant hands and subdominant hands in pegboard tasks were significantly higher in research group than in control group (P＜0.05).Conpletion time of connection test A,color connection 1 and 2 in connection test of research group were significantly higher than those of control group (P＜0.05).Attempt number and correct number in research group in PASAT test were significantly lower than in control group (P＜0.05).Number of search errors in research group was higher than in control group,while number of search correct,search total score and digital sign score were significantly lower than in control group (P＜0.05).Total number of words,color and color / word count in research group were lower than in control group in Stroop color word test,and the difference was statistically significant (P＜0.05).WMS-Ⅲ test results between two group had no significant difference (P＞0.05).Conclusion:The neurocognitive function in early stage in patients with first-episode schizophrenia has been extensively damaged.

ObjectiveTo investigate the protective effect of hepatocyte growth-promoting factor (PHGF) against liver ischemia-reperfusion injury in rats and its mechanism of its action. MethodsA total of 80 healthy male Sprague-Dawley rats were randomly divided into experimental group (PHGF group) and control group (NS group), with 40 rats in each group. A rat model of liver ischemia-reperfusion injury was established by 70% liver ischemia caused by the occlusion of blood flow in the middle and left lobes of the liver, with an ischemia time of 21 minutes. The rats in the PHGF group were given intraperitoneal injection of PHGF for intervention before surgery, and those in the NS group were given an equal volume of normal saline. Serum and liver tissue samples were collected before surgery and on days 1, 3, 5, and 7 after surgery, and the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBil) were measured; HE staining was used to observe pathological changes; real-time PCR was used to measure the mRNA expression of mitochondrial transcription factor A (TFAM) in the liver. The independent samples t-test was used for comparison of continuous data between two groups. ResultsHE staining showed that compared with the NS group, the PHGF group had significantly lower degrees of hepatocyte swelling, inflammatory cell infiltration, and hepatocyte necrosis under a light microscope. Liver biochemistry showed that on days 1, 3, 5, and 7 after surgery, the PHGF group had significantly lower serum levels of ALT, AST, and TBil than the NS group (t=11.879, 16.019, 22168, 10.235, 9.041, 12.936, 18.759, 8.142, 10.108, 11.014, 13.245, and 9.968, all P＜0.001). Real-time PCR showed that on days 1, 3, and 5 after surgery, the PHGF group had a significantly higher mRNA level of TFAM in the liver than the NS group (t=7998, 14.764, and 13.861, all P＜0.001). ConclusionPHGF preconditioning exerts a protective effect against liver ischemia-reperfusion injury in rats, possibly by upregulating the expression of TFAM to alleviate liver ischemia-reperfusion injury.

Objective:To investigate the promotive effect of 4,5,6,7-tetrabromobenzotriazole (TBB) on the apoptosis of the human cervical cancer HeLa cells,and to clarify its effect mechanism in related signaling pathways.Methods:The human cervical cancer HeLa cells at logarithmic growth phase were divided into control group(without TBB) and experiment group(with TBB).MTT assay was used to detect the survival rate of the HeLa cells;the morphology of HeLa cells was observed under inverted microscope;Annexin Ⅴ-FITC/PI double staining and flow cytometry(FCM) were used to determine the apoptotic rates of the HeLa cells;the expression levels of apoptosis-related proteins p-Akt,Akt,Bcl-2,Bax,cleaved-caspase-3,and Pro-caspase-3 were detected by Western blotting method.Results:The MTT results showed that the survival rates of the HeLa cells in experiment group were significantly decreased(P<0.01) in a dose-dependent manner compared with control group.The apoptotic morphology of the HeLa cells in experiment group were found as cell shrinkage and karyopyknosis under inverted microscope.The Annexin Ⅴ-FITC/PI double staining and FCM results showed that the apoptotic rates of the HeLa cells in experiment group (3,6,12 and 24 h) were higher than that in control group (P<0.05 or P<0.01).The Western blotting results showed that compared with control group,the expression levels of the anti-apoptotic proteins p-Akt and Bcl-2 in HeLa cells in experiment group were decreased obviously,whereas the expression levels of the pro-apoptotic proteins Bax and cleaved-caspase-3 were increased and the expression levels of Pro-caspase-3 were decreased.Conclusion:TBB may promote the apoptosis of human cervical cancer HeLa cells by inhibiting the Akt signaling pathway.

OBJECTIVE The antagonism of obidoxi me on sarin induced miosis and visual impair-ment was evaluated and its antagonistic mechanism was investigated.METHODS ① 30 min after sarin (2 μg /0.1 mL per eye)was given as an eyedrop,the ability of the 2.5%,5.0%,7.5% obidoxi me and 1 .0% atropine to reverse effects of sarin on pupil dia meter and light reflex were evaluated at different ti mes.② Another 36 rabbits received sarin and at 30 min afer sarin exposure,the drugs above were ad-ministrated and their effects on pupillary light reflex,as well as the AChE activity of cornea,iris and reti-na were recorded 4h after the treatment.RESULTS ① Miosis and impaired pupillary light reflex oc-curred soon after sarin exposure but the abnormal pupil width and pupillary light reflex had disappeared by 48 h after sarin exposure;Subcequent to 1 .0% atropine treatment,the pupil dilatedinstead while the impaired light reflex did not i mprove significantly;unlike atropine,soon after ad ministration of 2.5%, 5.0%,7.5% obidoxi me,the pupil dia meter and light reflex were significantly increased(P <0.01 )and then had beco me normal totally by 24 h post-dose,much faster than those of the control and atropine treatment group.However,there was no significant difference in the recovery ti me between the different dose groups of obidoxi me.② 4h after treatment,the AChE activity in cornea and irisof sarin-treated group were (42 ±4)%,(26 ±2)%,respectively;the AChE activity in cornea of 2.5%,5.0%,7.5%obidoxi me were (74 ±1 1 )%,(81 ±10)% and (74 ±7)%,respectively,and the AChE activity in iris were(39 ±10)%,(43 ±8)% and (43 ±8)%,respectively ,co mpared with sarin-treated group,AChE activities of cornea and iris as well as light reflex of the obidoxi me-treated group were significantly increased(P<0.01 ).But there was no difference in light reflex and AChE activity between the sarin-treated and atropine-treated groups.CONCLUSION Obidoxi me showed better antagonism of sarin-induced ocular effects than that of the commonly used drug,atropine;the antagonistic mechanism is likely closely related to its rapid reactivation of the inhibited AChE in the cornea and iris.

Objective To evaluate liver biopsy for the diagnosis in liver transplant patients with suspected acute rejection. Methods From Oct. 2004 to Apr. 2005, liver biopsies were performed 53 times in 39 transplant cases. Results Based on Banff schema for grading liver allograft rejection, laboratory abnormalities and result of treatment, acute rejection was diagnosed on 16 episodes, preservation injury in 12, bile duct strictures in 9, drug-induced injury in 11, chronic rejection in 3 and acute hepatic failure in 2. Conclusions Hepatocyte ballooning with necrosis features preservation injury. Drug-induced injury commonly has a combination of hepatocyte denaturalization with mild portal inflammation. Histologic features of early bile duct strictures in liver biopsy show prominent bile ductular proliferation and the canalicular cholestasis with mild hepatocyte damage which help to exclude acute rejection.
