This study examined the clinical features of complications of congenital retinoschisis and the clinical efficacy of vitreoretinal surgery in the treatment of these complications. The clinical efficacy of surgical treatments was retrospectively analyzed in 10 patients with congenital retinoschisis (10 eyes) complicated with rhegmatogenous retinal detachment (n=5), vitreous hemorrhage (n=2) and macula- involving schisis (n=1). All the patients suffered foveal and peripheral schisis. They were treated with scleral buckling (n=1) or vitrectomy (n=9). After the surgical treatment, the retina was reattached in patients with rhegmatogenous retinal detachment; the refractive media became transparent in those with vitreous hemorrhage; the visual acuity in 80% of patients was improved; no remarkable progression of schisis was found; no severe operative complications occurred. It was concluded that vitreoretinal surgery in the treatment of complications of congenital retinoschisis is safe and effective, and helps improve and maintain the visual function.

OBJECTIVE:To explore the mode,methods and role of clinical pharmacists providing pharmaceutical care for pa-tients with natural killer/T-cell lymphoma (NK/TL) complicated with diabetes. METHODS:Clinical pharmacists participated in SMILE chemotherapy plan for a NK/TL patients with diabetes mellitus,evaluated potential chemotherapy risk during first chemo-therapy,implemented individual medication monitoring and put forward suggestion. It included insulin injection 4 U,ivgtt,to con-trol the increase of blood glucose induced by dexamethasone;sodium bicarbonate 40 ml,ivgtt,bid to alkalize urine;allopurinol 0.1 g,po,tid to inhibit uric acid;fluid infusion 4 000 ml/d to prevent renal failure;mesna 0.4 g/time to protect urinary passage;monitorring potential allergic reaction and arrest of bone marrow;providing medication education on the application of calcium foli-nate in SMILE chemotherapy regimen. RESULTS:Physicians adopted the suggestions of clinical pharmacist,and chemotherapy was carried out smoothly. No ADR was found,and patients manifested good medication compliance. CONCLUSIONS:Clinical pharmacists participate in chemotherapy,evaluate potential risk and provide individual medication monitoring,which optimize ther-apy plan,reduce medication risk and guarantee the safety of drug use.

A comparison of plant and animal stem cells can highlight core aspects of stem-cell biology. In both kingdoms, stem cells are defined by their clonogenic properties and are maintained by intercellular signals. The signaling molecules are different in plants and animals stem cell niches, but the roles of argonaute and polycomb group proteins suggest that there are some molecular similarities.

Objective To evaluate the clinical efficacy of sodium tanshinone IIA sulfonate(STS)in the treatment of ad-vanced schistosomiasis. Methods Fifty cases with advanced schistosomiasis admitted to the Touzao Township Hospital of Dong-tai City during the period from November 2012 to November 2013 were treated with STS for 10 days,and the internal diameter of the portal vein,levels of ALT,AST,γ-GT,PIIIP,CIV,HA and LN were measured and compared before and after the adminis-tration of STS. Results The mean levels of all serological parameters except HA were within the normal range before STS treat-ment,while the highest positive rate was detected inγ-GT(26.0%)and HA(54.0%). Following the STS treatment,the mean lev-els of all parameters and the positive rates reduced,with the greatest reduction observed inγ-GT(36.7%)and HA(37.8%);how-ever,the mean HA level was still higher than the normal range. The mean internal diameter of the portal vein reduced from(10.5± 1.7)mm before the STS treatment to(9.8±1.3)mm after the STS administration,with a significant diffrtence(P<0.05). Conclu-sion STS appears effective in the treatment of advanced schistosomiasis.

Objective cAMP promotes neurite outgrowth in vitro. The study is aimed to understand whether cAMP can repair spinal cord injury of rats. Methods 56 rats models of spinal cord hemisection were adopted and randomly distributed into six groups. Dibutyryl-cAMP or physiological saline was injected either once in the motor cortex with an amount of 6 ml of 50 mmol/L cAMP, or continuously infused through a polyethylene tube connecting with a micro-pump in the spinal lesion area or in the subarachnoid space with a total amount of 72 ml of 10 mmol/L cAMP for 72 h. The distribution of neurofilament (NF) in the lesion area was observed by immunohistochemistry. Corticospinal tracts (CST) and spinal axons regeneration were investigated by CST and spinal axons anterograde tracing with biotinylated dextran amine (BDA). The function of hindlimb movements were evaluated by BBB scales and as a reference to assess the repairing effect of treating strategy. Results NF were densely distributed and extended in the lesion area in the cAMP groups, but no connection could be found with the NF in the caudal. No axonal regeneration could be achieved when cAMP was input into the subarachnoid space. Many regenerated axons, including some CST axonal regeneration were presented in the lesion areas in cAMP groups though no continuous long regenerated axons traversed the lesion area, while there was no regenerated axon in the lesion areas in the control groups. All the rats restored to normally walk 4 to 5 weeks after operations, BBB scale exceed 20, and no significant difference between cAMP groups and control groups by comparing the BBB scales of hindlimb movements. Conclusion cAMP injected in the brain cortex or continuously infused in the spinal lesion area can induce the axonal regeneration and is beneficial to repair the spinal cord injury, but could not directly promote hindlimb movements recovering.

Objective To investigate the sensitivity of different methods in the diagnosis of portal hypertension associated with liver cirrhosis. Methods 99 patients with portal hypertension associated liver cirrhosis, and 49 healthy subjects as control were enrolled in this study. Their portal and splenic vein widths, and the conditions of varicose vein in esophagus and gastric fundus were determined, and portal pressures were measured by radionuclide method. The positive percentage of different methods for the diagnosis of portal hypertension were analysed. Results Most of the patients with portal hypertension had the extension of portal and splenic vein in the fifferent areas and in various degrees. There were no significant differences in the degrees of portal and splenic vein extension among the patients with mild, moderate or severe esophageal varicose vein. The width of portal and splenic vein was not related with portal pressure. Radionuclide method was the most sensitive in diagnosing portal hypertension. Conclusion Portal hypertension can be diagnosed according to the conditions of vessels and spleen. The sensitivity of different methods in diagnosing portal hypertension were different, and that of radionuclide method was the highest. The width of portal and splenic vein had no close relation with portal pressure and the degree of esophageal varicose vein.

Objective To establish the animal model of periventricular leukomalacia (PVL) caused by lipopolysaccharide (LPS) and investigate the immune mechanisms in the pathogenesis of cerebral palsy due to intrauterine infection. Methods Twenty-six mature pregnant Wistar rats were divided into experiment(n= 15)and control groups(n =11). LPS(0. 3 mg/kg) and distilled water were injected on 15 days of gestation to two groups respectively intraperitoneally. One hundred and twenty-eight neonatal rats of experiment group and 105 in the control group were obtained till the gestation day of 21. The level of IL-2, TNF-? and histology changes in neonatal rats' brain were observed by HE staining and RIA, water content in brain tissues were compared. Results IL-2[(3. 56?0. 450) ng/g] and TNF-? concentrations [(8. 23?0. 47)ng/g] in neonatal rats' brain of the experiment group were significantly higher than those in the control group [(0. 78?0. 2)ng/g and (5. 23?0. 32)ng/g, P

Objective To explore clinical characteristics of the digestive tract obstruction due to annular pancreas. Methods We reviewed retrospectively clinical features, operative findings and the autopsy of 5 children with annular pancreas. Results Neonate patients usually present complete upper gastro intestinal obstruction because most of them were complicated with duodenal atresia. Infants present chronic incomplete intestinal obstruction duo to annular pancreas. 35.8% of duodenal constriction was caused by annular pancreas. Conclusions All the symptomatic patients with annular pancreas should undergo exploration to restore the consecution of the digestive tract and to detect if there is a concurrent malformation such as intestinal atresia.
