AIM:To explore the potentially beneficial clinical effects of traditional Chinese medicine(TCM) combined with photocoagulation for diabetic retinopathy(DR).METHODS:Chinese patients with DR were divided into two groups. A joint treatment group received both the TCM ziyinliangxuesanyutang and photocoagulation, while a control group received only photocoagulation laser treatment. Visual acuity tests, visual field retinal sensitivity tests, and fundus fluorescein angiography (to measure neovascular regression) were performed. Vision was compared between the two groups 1 month, 6, and 12 months after treatment.RESULTS:Twelve months after treatment, the recovery of visual acuity (62.3% vs 43.1%, P=0.037) and retinal sensitivity \[17.0±3.7 decibels (dB) vs 14.9±3.7dB, P=0.002\] as well as neovascular regression (67.2% vs 48.3%, P=0.036) in the joint treatment group were all significantly greater than that of the control group.CONCLUSION:Compared with laser treatment alone, the joint application of TCM and photocoagulation is shown to be more effective than DR treatment method.

OBJECTIVETo investigate the diagnosis and treatment of malignant fibrous histiocytoma of the retroperitoneum (MFHR).

METHODSThe clinicopathological features, treatment and prognosis of 31 patients with MFHR were retrospectively analyzed.

RESULTSThe mean age of the patients was 52.7 +/- 14.1 years. Male:Female = 22:9. The primary symptoms were abdominal mass and pain. The average diameter of tumor was 15 cm. The histopathologic types of the tumor were inflammatory, storiform-pleomorphic, myxoid and giant cell in 16, 10, 4 and 1 cases. The overall survival rate of 1-, 3- and 5-year was 61.3% +/- 9.8%, 31.6% +/- 11.3% and 21.1% +/- 11.4% with a median survival time of 17.0 +/- 6.3 months. Complete resection of the tumor was the major prognostic factor. Postoperative radiotherapy of 20 - 45 Gy was able to prolong the median survival from 12.1 +/- 11.6 months of surgery alone to 26.4 +/- 22.0 months of surgery plus postoperative radiotherapy though without statistical significance (P = 0.051). Postoperative CHOP chemotherapy was not shown to be beneficial.

CONCLUSIONChemotherapy remains the important method of cure. The survival in patients with MFHR might be improved by complete resection combined with chemotherapy or/and radiotherapy.

OBJECTIVEPeripheral nerve regeneration depends on gene regulation by central neurons. To search for more effective treatment methods to improve the regeneration of wounded peripheral nerves, gene expression profile of spinal cord after firearm injury to rabbit sciatic nerves are studied with DNA micro-array technique.

METHODSA total of 54 rabbits were randomly divided into 4 groups: Groups d1, d3, d7 and normal control group. Lumbar spinal cords were sampled. RNA and mRNA were extracted, labeled by Cy3 and Cy5, and analyzed by mouse_8192S gene chips.

RESULTSA total of 1367, 923, and 61 genes with differential expression were found on day 1, day 3, and day 7 after trauma respectively. Five expressed sequence tag (EST) sequences demonstrated differential expression during 7 days after trauma.

CONCLUSIONSThere is complex gene profile with differential expression after firearm nerve injury, among which AW701496, U84291, W13926, X04017 and AW822394 EST sequences may be important regulation factors that involved in regeneration of peripheral nerve injury.

Objective By detecting the distribution and homology analysis of Acinetobacter baumanii in the ICU ward,to con-trol nosocomial infection,provide theoretical basis to take effective measures.Methods From January 2016,20 patients in ICU of Shaanxi Provincial People's Hospital were taken into group.The samples of sputum and surrounding environment samples were cultured.The homology of Acinetobacter baumannii was analyzed by MALDI-Biotyper software,antimicrobial susceptibility test was analyzed by K-B.Results 27 strains of Acinetobacter baumannii were detected,mainly comes from sputum,hands of medical staffs and the environment,homology analysis results showed that the 27 strains of Acinetobacter baumannii was divided into two clusters(Ⅰtype 1 1 strains,Ⅱ type 1 6 strains),most of Acinetobacter baumannii were multi-resistant bacteria,except for the polymyxin B,minocycline and SCF.Conclusion The ways of transmission of Acineto-bacter baumanii in ICU were by medical personnel hand,pollution of the medical equipment and so on,strengthening the dis-infection and reasonable application of antimicrobial agents were taken advantageous for the prevention and control of acine-tobacter baumannii infection and transmission.

OBJECTIVE: Study on the application of WAIS-RC short forms and adult intelligence disability scale in mental impairment assessment. METHODS: Mental impairment assessment cases between July 2009 and March 2011 in judicial appraisal institute of Taizhou University were collected. Assessment results obtained with the WAIS-RC short forms and adult intelligence disability scale were compared with the experts assessing conclusions and analyzed using SPSS 11.5 software. RESULTS: Assessment results with the two scales did not fully comply with the expert's conclusions, with reliability coefficient were 0.785 and 0.940 respectively, correlation coefficient were 0.850 and 0.922 respectively. CONCLUSION The intelligence assessment was influenced by many factors. When the appraised individuals had nerve dysfunction and mild intelligence disability or mental disorders, the two scales should be used together. When the appraised individuals had moderate intelligence disability or mental disorders, adult intelligence disability scale had advantage.

OBJECTIVETo investigate the changes of proton transportation across the inner mitochondrial membrane (IMM) and H(+)-ATPase of hepatocytes in endotoxic shock rats.

METHODSEndotoxin from E. Coil of 5.0 mg/kg or saline of 1 ml/kg was injected into the femoral vein. The rats were sacrificed pre-injection and 1, 3, 5, 8 hours after injection, and plasma and liver tissue samples were collected respectively. The liver tissue samples were used for preparation of mitochondria and submitochondrial particles (SMPs). The proton-translocation of SMPs and H(+)-ATPase, phospholipase A(2) (PLA(2)) activities and malondialdehyde (MDA) content, membrane fluidities of different level of mitochondria membrane and plasma MDA content were assayed.

RESULTS(1) Five hours after E. Coli. O111B4 injection, the maximum fluorescence quenching ACMA after adding ATP, nicotinamide adenin dinucleoacid hydrogen (NADH), and the succinate were significantly decreased (P<0.05). The time of maximum fluorescent quenching and the half time of fluorescent quenching were significantly prolonged (P<0.01), especially when NADH was used as a substrate. (2) The mitochondrial H(+)-ATPase activity was significantly increased at early stage of endotoxic shock (P<0.05), and significantly decreased at late stage of endotoxic shock (P<0.01). (3) The mitochondrial membrane bound PLA(2) activity, plasmal and mitochondrial MDA content were significantly increased and succinate dehydrogenase (SDH) activity of mitochondria decreased markedly in endotoxic shock rats (P<0.05). (4) The mitochondrial membrane fluidity of different lipid regions was decreased, especially in the head of phospholipid.

CONCLUSIONSProton transportation across IMM and mitochondrial H(+)-ATPase activity are significantly decreased in endotoxic shock.
