Objective To observe effect of arginine on wound healing of diabetic rats.Meth- ods Forty male Lewis rats were equally and randomly divided into diabetic group and normal control group.The diabetic group were rendered with diabetic by using intraperitoneal(IP)streptozotocin seven days prior to surgery and underwent a dorsal skin incision with implantation of polyvinyl-alcohol sponges. Either of two groups were subdivided into arginine treatment group and saline treatment group,10 rats in each group,of which the arginine treatment group received arginine at 1 g/kg per day by IP injection, while the saline treatment group received saline injection only.Animals were sacrificed 10 days post wound to observe antibreakage tension,hydroxyproline content and mRNA expression of procollagenⅠandⅢ.Results Diabetic wounds had greatly decreased breaking strengths compared with controls. Arginine significantly enhanced wound breaking strengths,increased wound hydroxyproline levels and ele- vated mRNA for procollagenⅠandⅢin both diabetic and control animals as compared to their saline-trea- ted counterparts.Conclusion Arginine can effectively promote healing of diabetic wounds in rats.

Siegesbeckia pubescens (SP) has been used as a traditional medicine for the treatment of and inflammatory diseases.However,the activities of SP against hepatocellular carcinoma and the related mechanisms remain unclear.The present study aimed to examine the effects of the essential oil of SP (SPEO) on the proliferation of hepatocellular carcinoma cells and the possible mechanisms.The growth inhibition of HepG2 cells was analyzed by MTT assay.Hoechst 33258 and fluorescence microscopy were utilized to observe the nuclear morphological changes of apoptotic cells.Flow cytometry was used to detect cell apoptosis and cell cycle.The expressions of the target proteins were detected by Western blotting.The results showed that SPEO obviously inhibited the proliferation of HepG2 cells in a dose-dependent manner.SPEO activated a series of apoptotic proteins in HepG2 cells,increasing expression levels of Bax,caspase-3 and caspase-9,and decreasing the bcl-2 expression level.SPEO displayed promising anti-hepatocellular carcinoma activities in vitro,partly by inducing apoptosis in HepG2 cells through activating the mitochondrial pathway.

Objective To create a simple differential diagnostic rule for tuberculous meningitis and cryptococcal meningitis in adults on the basis of basic clinical and laboratory features. Methods We compared the clinical and laboratory features of 219 adults admitted to our hospital during the period of 2000-2008; these patients satisfied the diagnostic criteria for tuberculous meningitis (n=100) and cryptococcal meningitis (n=119). Multivariate logistic regression analysis was employed to find the risk factors those could independently predict the tuberculous meningitis,so that the diagnostic rule could be created. Results Six risk factors those could independently predict the tuberculous meningitis were found, including gender, mind disorder, vision and/or hearing damage, amount of cerebrospinal fluid protein, total cerebrospinal fluid white-cell count and combination with periphery tuberculosis. A diagnostic rule developed from these features enjoyed a 78.0% sensitivity, a 95.2% specificity, a 92.9% positive predictive value and a 84.4% negative predictive value. Conclusion Simple clinical and laboratory features can help in the differential diagnosis between adult tuberculous meningitis and cryptococcal meningitis, which can be applied in primary hospital with limited microbiological resources.

OBJECTIVETo investigate the expression and distribution of mast cell tryptase (MCT) in scar, and to discuss the different MCT gene expression in keloid, hypertrophic scar and normal skin.

METHODS20 samples of keloid, 20 samples of hypertrophic scar and 20 samples of normal skin were collected. The distribution of MCT was investigated by immunofluorescence histochemistry, and the MCT mRNA expression was detected by Relative Quantification real-time fluorescent PCR.

RESULTSMCT gene was mainly located in the collagen fiber bundles of the scar, especially in the superficial layer of scar. MCT mRNA expression was significantly higher in keloid than that in hypertrophic scar and normal skin (P < 0.01). Averagely, the MCT gene expression in keloid was 2.5 times and 5.4 times of that in hypertrophic scar and normal skin.

CONCLUSIONSMCT gene may play a role in the pathogenesis of scar.

OBJECTIVETo analyze the advantages of spatial measurement of anatomical parameters in a 3D model in surgical planning for laparoscopic partial nephrectomy (LPN).

METHODSFrom February, 2016 to October, 2017, 37 patients diagnosed with T1 renal mass underwent LPN based on 3D reconstruction after enhanced CT scanning using the Uromedix-3D system (group A), and another 38 patients received LPN with conventional CT planning (group B). The anatomical parameters were measured in the reconstructed 3D model and the demographic data, surgical outcome and postoperative data were compared between the two groups.

RESULTSIn group A, the average time for 3D model reconstruction was (29.3∓9.7) min; the length, width and depth of the renal defect in 3D model were 3.2∓1.1 cm, 2.6∓0.9 cm and 1.7∓0.7 cm, respectively; The distance of the tumor from the collecting system was 3.8∓2.2 mm; The mean R.E.N.A.L score of the patients was 7∓1.5, and 3 patients had accessory renal artery and 2 had early branching of the renal artery. LPNs were completed via the retroperitoneal approach in all the 75 patients without conversion to open or total nephrectomy. Group A and group B showed significant differences in warm ischemic time (26.7∓6.4 vs 31.9∓7.0 min), tumor-excision time (8.4∓2.6 vs 10.4∓2.8 min), renal defect suture time (18.3∓3.9 vs 21.5∓3.4 min), 24-h volume of retroperitoneal drainage (88.6∓40.2 vs 134.3∓58.3 mL) and 48-h volume of retroperitoneal drainage (127.9∓54.5 vs 198.1∓86.3 mL), but not in the demographic data, operation time, intraoperative blood loss or postoperative hospital stay.

CONCLUSIONS3D reconstruction of the renal masses can be completed efficiently and accurately using this system. Compared with conventional CT-based measurement, 3D spatial measurement of the anatomical structures helps to increase the precision in the performance of LPN and reduce the warm ischemia time.

Objective To investigate the correlation between Chlamydia pneumonia (Cpn)infection and chronic obstructive pulmonary disease (COPD).Methods 82 patients with acute exacerbation COPD (AE-COPD) or stabilized COPD patients at outpatient visits,in the People' s Hospital of Jiangyin city from Aug.2010 to May 2012,together with 46 cases having stationary phase COPD and 38 healthy volunteers as control group,were involved in this study.Patients were bled 2 ml,on the next day of hospitalization while patients at emergency room were bled 2 ml immediately,but bled again on the 15th day.Serum was separated through cryopreservation and the Cpn antibodies (IgG,IgM and IgA antibodies) were detected,under micro-immunofluorescence.Results In terms of IgG in the three groups,the positive rates did not show significant differences (P＞0.05) but the GMT of the IgG in the AE-COPD group was significantly higher (P＜0.01) than that in the control group.IgA positive rate among the three groups; AE-COPD appeared the highest.There was no significant difference between the AE-COPD group and stationary phase COPD group (P＞0.05),however,there were significant differences between the AE-COPD group,the stationary phase COPD group and the control group (P＜0.01).In terms of GMT of IgA in the three groups,there was significant difference between the AE-COPD group and stationary phase COPD group (P＞0.05),but with significant difference between the AE-COPD group and the control group (P＞0.01).There was significant difference between stationary phase COPD group and the control group (P＞0.05).When comparing both the rates of acute infection and chronic infection on the AE-COPD groups with the control group,there appeared significant differences (P＜0.05,P＜0.01).When comparing the acute and chronic infection between the stationary phase COPD group and the control group,the rate of acute infection did not show significant difference (P＞0.05) while the chronic infection rate appear to have had significant difference (P＜0.01).Conclusion Cpn infection seemed to be closely related to the development of COPD.

Objective To explore the suicide intention and its influential factors among primary and junior high school students in rural areas of Anhui province,in order to provide evidence for early intervention related to mental health problems.Methods All students from 3 junior high and 5 primary schools in Changfeng county of Anhui were recruited as the study subjects using the cluster sampling method.Data were collected by using Children' s Depression Inventory,the Family APGAR Index,the Trait Coping Style Questionnaire,the Children' s Self-Esteem Scale,Social Anxiety Scale for Children,and the Quality of Life Scale.Chi-square test and Logistic regression were used to analyze the suicidal ideation and its influential factors respectively.Results 8.64％ (252/2917) of the studied children had suicidal ideation.Out of them,9.80％ (166/1694) and 7.03％ (86/1223) were left-behind or non-left-behind children.There was statistically significant difference on suicide ideation between the left-behind children and non-left-behind children (P=0.015).Data from the multivariate logistic regression analysis showed that social anxiety and negative coping style were the risk factors for suicidal ideation (P ＜0.05) while better family function and quality of life were the protective factors of suicidal ideation (P＜0.05).Conclusion Suicide ideation was relatively prevalent among rural children in Anhui province.Family,school and society should carry out different kinds of preventive measures to prevent suicide related behaviors in children from this area.
