Objective To observe and analyze the characteristics and trends of the liver and gallbladder damage caused by long-term use of anti schizophrenia drugs through the observation of the abdominal ultrasound. Methods From August 2013 to April 2016, the patients diagnosed as schizophrenia and met criterions were enrolled in our hospital. The observation group I included patients taking anti schizophrenia drug for 3 to 5 years. The observation group II included patients taking anti schizophrenia drug more than 5 years. In addition, the control group recruited healthy person who were over 30 years old and had never taken anti-schizophrenia drug. The change in ultrasound of liver and gallbladder were recorded and analyzed. Results The rate of cholecystolithiasis, chronic cholecystitis in observation group II were higher than those in the other two groups (P<0.05), while there had no significant difference between observation group I and control group. The rate of pure fatty liver in observation group II were higher than those incontrol group (P<0.05), while there had no significant difference between observation group I and observation group II, and there had no significant difference between observation group I and control group. There had no significant difference among three groups regarding as the rate of hepatic cyst and hepatic cavernous hemangioma. Conclusion Long-term use of anti-schizophrenia drugs could increase the risk ofcholecystolithiasis, chronic cholecystitis and pure fatty liver .

Organ transplantation relies on organ donation,which is an 'altruistic behavior'.In order to sever the shortage of organ donors we should develop citizen education which is correlative to it,The mode and methods of citizen education on organ donation includes: education by schools and society,edifying and typical examples,self-education and internalized morality.

Objective　To establish the normal growth velocity of fetal liver length and compare them with those of intrauterine growth retardation, pregnant diabetes and maternal-fetal blood types imcopatible. Method　Three hundred and five normal pregnant women and 24, 10, 16 pathological pregnant women of intrauterine growth retardation (IUGR), gestational diabetes and maternal-fetal blood types incompatible respectively had ultrasonographic measurement of fetal liver length at 18 to 42 weeks′ gestation. Results　Normal fetal liver length has a linear relation to gestational age, and showed a significantly rapid increase after 28th week with a growth rate of 1.76 mm per week, and 1.00 mm per week before 28th week (P<0.05). The growth rate of IUGR group before and after therapy were 1.19 mm and 1.23 mm per week, significantly lower than those of normal group (P<0.05). The growth rate of pregnant diabetes group before and after therapy were 1.63 mm and 1.63 mm per week, no statistical significance with normal group (P>0.05). The growth rate of maternal-fetal blood types incompatible group before therapy was 1.98 mm, showed no difference with normal group (P>0.05), but after therapy, the growth rate of fetal liver was 1.38 mm per week, significantly lower than normal group (P<0.05). Conclusion　Dynamic measurement of fetal liver length can help us to understand whether the fetus grow well in uterus and whether the treatments are effective.

BACKGROUND: The previous methods for the repair of tendon defect include end-to-end method, autologous tendon graft, tendon al ograft or artificial tendon transplantation, but each method has its advantages and disadvantages. OBJECTIVE: To investigate the feasibility of constructing tissue-engineered tendon by rabbit bone marrow mesenchymal stem cells as seed cells which were induced by bone morphogenetic protein 12 and with col agen-polyglycolic acid composite as frameworks in the repair of rabbit tendon defects. METHODS: Bone marrow was separated from rabbit proximal femur to harvest cells, and the cells were passaged to the second generation and induced with 10 μg/L bone morphogenetic protein 12. Then the passage 2 cells were implanted into the prefabricated tissue-engineered tendon on the polyglycolic acid stitch with certain percentage together with col agenⅠsolution. The rabbits were used to establish the Achil es tendon defect models, and different methods were used to repair Achil es tendon defect: tissue-engineered tendon, col agenⅠ-polyglycolic acid stitch and end-to-end suturing in silk. Morphology, mechanics and shistopathology of the tissue-engineered tendon were observed. RESULTS AND CONCLUSION: Pathomorphological observation of histological section after 12 weeks showed that multiple fusiform fibroblasts were homogeneously distributed in col agen in the direction of stress mechanics.Fibrocytes increased obviously, new smal vessels could be seen and col agen was found aligned compactedly. In col agen Ⅰ-polyglycolic acid stitch group, a part of fibroplasia hyperplasia accompanied by granulation tissue formation could be seen, the col age fibers were in loose filamentous network and the cells were distributed disorderly and unevenly. Granulation tissue formed around the fibrous tissue in the silk group. Biomechanics strength in bone morphogenetic protein 12+polyglycolic acid group was better than that in the col agen Ⅰ-polyglycolic acid group, and there was significant difference when compared with suture silk group. The biomechanics strength of the bone morphogenetic protein 12+polyglycolic acid group was lower than that of normal tendon. It is possible to construct a tissue-engineered tendon with autologous bone marrow mesenchymal stem cells as seed cells induced by bone morphogenetic protein 12 and with the col agen-polyglycolic acid as the framework. Constructed tissue-engineered tendon has biomechanics characteristics and can be used to repair Achil es tendon defect.

Objective To determine the clinical indicators of early death (within 72 hours) in patients with acute paraquat poisoning.Methods The data of 93 acute paraquat poisoning patients admitted to emergency intensive care unit (EICU) of the First Hospital of China Medical University were retrospectively analyzed.The patients were divided into two groups according to whether they died within 72 hours or not.The gender,age,poison dose,paraquat concentration in urine,reduction of paraquat amount in urine after each hemoperfusion,and the worst value of white blood cell (WBC) count,lymphocytes count,arterial blood gas analysis,blood K +,Na+,Cl-,and serum amylase,serum lipase,serum total bilirubin,troponin Ⅰ,creatine kinase (CK),blood urea nitrogen,serum creatinine within 24 hours after poisoning were compared.Spearman correlation analysis was used to analyze the correlation between paraquat concentration in urine and the dose of paraquat.The predictive value of each indicator at death in early stage of poisoning was analyzed with receiver operating characteristic curve (ROC curve).Results Nineteen patients in the group of those died in early stage of poisoning (within 72 hours) resulted in a mortality rate of 20.4％.Compared with non-early death group,in early death group,the value of poison dose (mL:133.4 ± 108.8 vs.58.6 ± 40.0,t=3.145,P=0.002),paraquat concentration in urine [mg/L:16.34 (11.87,96.76) vs.4.46 (1.21,12.78),Z=-3.422,P=0.001],WBC (× 109/L:22.63 ±9.72 vs.14.95 ±8.39,t=3.446,P=0.001),blood lactate [Lac (mmol/L):6.7 (2.2,12.1) vs.1.9 (1.1,3.4),Z=-3.294,P=0.001] were significantly higher,and the reduction rate of paraquat concentration in urine after first perfusion [(38.4 ± 15.63)％ vs.(67.59 ± 27.87)％,t=2.945,P=0.004] and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg=0.133 kPa):28.7 ± 9.3 vs.34.8 ± 6.7,t=-3.245,P=0.002] were significantly lowered.There was no significant difference between two groups in other indexes.Poison dose and paraquat concentration in urine showed significantly positive correlation (r=0.450,P＜0.001).ROC curve showed that the predictive value of paraquat concentration in urine,WBC,and Lac in early death were significant [area under the ROC curve (AUC) of paraquat concentrations in urine was 0.806,95％ confidence interval (95％CI) 0.699-0.913,the cut-off value was 11.64 mg/L,with sensitivity 84.6％,specificity 71.4％; AUC of WBC was 0.734,95％CI 0.569-0.899,the cut-off value was 15.94 × 109/L with sensitivity 69.2％,specificity 76.8％ ; AUC of Lac was 0.729,95％CI 0.568-0.891,the cut-off value was 1.95 mmol/L with sensitivity 84.6％,specificity 42.9％].Conclusions Paraquat concentrations in urine,WBC,Lac,poison dose and PaCO2 were the risk factors of the early death of the acute paraquat poisoning.The research suggests that paraquat concentration in urine,WBC and Lac are valuable in predicting early death of the patients.

OBJECTIVE: To investigate the changes of neuropeptides content in a rat model of spleen-deficiency syndrome. METHODS: Rats were randomly divided into three groups: normal group, untreated group and treatment group. There were ten rats in each group. Spleen-deficiency syndrome was induced by intragastrically administration of rhubarb concentrate in rats of the untreated and treatment group. The rats in the treatment group were intragastrically administered with Sijunzi decoction, a traditional Chinese compound herbal medicine for strengthening spleen and supporting qi. Normal saline was intragastrically administered to the rats in the normal and untreated groups. The somatostatin (SS) and cholecystokinin-8 (CCK-8) content in hypothalamus and colons was detected by the method of radioimmunoassay and the D-xylose content in urine was also detected. RESULTS: The CCK-8 content in hypothalamus of the untreated group was higher than that of the normal group (P<0.05). SS and CCK-8 content in colons of the untreated group was higher than that of the normal group (P<0.05). The CCK-8 content in colons of the untreated group was lower than that of the treatment group (P<0.05). The excretion rate of D-xylose in the untreated group was lower than that of the normal group (P<0.05). CONCLUSION: The disorder of neuroendocrine regulation in rats with spleen-deficiency syndrome may be chiefly responsible for "spleen-deficency and dysfunction of spleen" in traditional Chinese medicine.
