The priority of the modernization of Chinese medicine at present is the standardization of Chinese medicine practice, including syndrome differentiation, disease diagnosis, standardized therapeutic program, etc. For this reason, the primary work is to establish a concise disease-syndrome differentiation and treatment system (CDSDTS) under the guidance of Chinese medicine theory, holding the core advantages and effectiveness of Chinese medicine, and aiming at creating a simplified theoretical and practical program facilitating for operation and spreading. It is not a mere simplification or careless reduction, but a normalized program of treatment according to the essence of Chinese medicine. Although the therapeutic effect might be somewhat lost, it can be widely approved, thereby, it would make contributions for the inheritance and development of Chinese medicine.

Objective To investigate the effect of partial body-weight supported treadmill training ( PBW- STT) on function of lower limbs, walk function, ADL performance and quality of life of hemiplegic patient induced by cerebral infarction. Methods A total of 132 cerebral infarction patients were divided into a control group (n = 69) and a training group( n = 63) randomly. Both groups accepted routine rehabilitation therapy, and the training group accepted PBWSTT at the same time in addition. Both groups were evaluated with regard to their walking ability, func- tion of lower limbs, ADL performance and their quality of life by using Functional Ambulation Category (FAC) , Fugl-Meyer assessment (FMA) , Barthel index (BI) and SF-36 before and after rehabilitation treatment. Results The function of lower limb, walking ability, ADL performance and the quality of life of both groups were improved significantly after treatment, and those in the training group were improved to a significantly greater extent than those in the control group ( P

OBJECTIVETo investigate the effects of human cytomegalovirus (HCMV) on the proliferation of duct epithelial cells of human salivary gland (HSG).

METHODSThe expression of proliferating cell nuclear antigen (PCNA) and p53 were studied in 11 cases of parotid cytomegalic inclusive disease (PCID) using immunohistochemical staining method. The effects of human cytomegalovirus (HCMV) on the proliferation of HSG were investigated by MTT method in vitro. The expression of PCNA in HSG infected by HCMV was examined using immunocytochemical staining and Western blotting.

RESULTSPCNA was expressed weakly in most of megalic inclusion cells which were positive for HCMV, while all the megalic inclusion cells were p53 negative in all 11 cases of PCID. HCMV inhibited proliferation of HSG in vitro in a time dependent and dose dependent manner. Down-regulation of PCNA was shown in infected cells.

CONCLUSIONHCMV inhibits proliferation of HSG and down-regulation of PCNA may be an expression of the inhibition.

OBJECTIVETo explore the correlations of circulating tumor cells (CTCs) and disseminated tumor cells (DTCs) with the clinicopathological characteristics, prognostic events, and survival outcomes in esophageal cancer (EC) patients.

METHODSThe PubMed, Web of Science, Embase database and Cochrane database were searched for studies reporting the outcomes of interest. The studies were selected according to established inclusion/exclusion criteria. Meta-analysis of the studies was performed using Review Manager 5.3 and Stata12.0 software with the odds ratio (OR), risk ratio (RR) , hazard ratio (HR) , and 95% confidence interval (95% CI) as the effect indexes.

RESULTSNineteen studies involving a total of 1766 patients were included in the analysis. Significant correlations of CTCs and DTCs were found with the clinicopathological parameters including the tumor stage (OR=1.95), depth of invasion (OR=1.99), lymph node metastasis (OR=2.44), distal metastasis (OR=5.98), histological differentiation (OR=1.67) and lymphovascular invasion (OR=4.48). CTCs and DTCs were also correlated with the prognostic events including relapse (RR=6.86) and metastasis (RR=3.22) and with the survival outcomes including the overall survival (OS) overall analysis (HR=3.46) and disease-free survival/progression-free survival (DFS/PFS) overall analysis (HR=3.00).

CONCLUSIONCTCs and DTCs are significantly associated with an advanced tumor stage, depth of tumor invasion, lymph node metastasis, distant metastasis before therapy, differentiation, lymphovascular invasion, relapse and metastasis in patients with EC. They are also significantly correlated with a poorer survival for OS and DFS/PFS to serve as clinical and prognostic predictors in patients with EC.

Objective: To examine sleep quality and related factors among middle school students,and to provide a scientific reference for making the relevart interventional measures. Methods: A cross-sectional questionnaire anonymous survey was conducted among 9 560 students randomly selected from Shanxi province using multi-stage stratified cluster sampling. Pittsburgh Sleep Quality Index (PSQI) was used to collect information on sleep quality. Results: Among all the participants, 2 255 (23.6%) middle school students were reported poor sleep quality. The prevalence of poor sleep quality was significantly higher in girls (24.5%) than in boys (22.4%)(χ2=5.93, P<0.05). Significant differences were observed in the prevalence of poor sleep quality between junior middle school (12.9%), senior middle school (36.6%) and vocational school students (24.6%) (χ2=636.07, P<0.01). The global PSQI, sleep duration and sleep disturbance scores were higher in girls than in boys (t=3.76，8.38，3.47，P<0.01). There were significant differences between students with different school stages in global PSQI, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping medication, and daytime dysfunction scores (F=727.43,83.69,1 670.07,8.24,26.19,4.20,609.80,P<0.05). Multivariable Logistic regression analysis showed that gender, school stage, academic pressure, parental marital state, relationship with teachers, physical activity, smoking and drinking were associated with poor sleep quality among middle school students in Shanxi. Conclusion Sleep problems are common among middle school students, and appropriate intervention should be taken to improve sleep quality of students from individual, school-and family level.

OBJECTIVETo investigate the expression of Yin Yang 1 (YY1) protein in human insulinoma and explore its clinical significance.

METHODSNineteen pancreatic neuroendocrine tumor tissue were collected from patients treated in Nanfang Hospital between 2000 and 2014. The protein expression of YY1 in benign and malignant insulinoma tissues were detected by immunohistochemistry.

RESULTSPositive expression for YY1 protein was detected in both benign and malignant tumor tissues, but the malignant tissues had a significantly greater intensity of YY1 expression than the benign tissues (P=0.042). The intensity of YY1 expression was positively correlated with the nature of the tumor, and the insulinomas with high expressions of YY1 had significantly greater malignant potentials (P=0.037).

CONCLUSIONThe high expression of YY1 protein is associated with the development of insulinima. YY1 may serve as a new tumor marker for detecting the malignant transformation of insulinoma.

This article reports the treatment of a patient suffered from acute radiation burn covering 41% TBSA, with deep partial-thickness and full-thickness injury, produced by exposure to a large-scale industrial electron accelerator. An open wound began to appear and enlarged gradually 10 weeks after the exposure. Serious wound infection with methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, pneumonia, respiratory failure, systemic inflammatory response syndrome, nephropathy and hypoproteinemia developed successively since 3 weeks after the wound formation. Skin grafts failed to survive, resulting in enlargement of the wound. After being treated with proper measures, including parenteral nutrition, respiratory support with a ventilator, appropriate antibiotics, steroid administration for nephropathy, deep debridement for wounds followed by skin grafting, the patient was cured and discharged after undergoing 15 operations in 500 days. The clinical condition of an extensive acute radiation burn is complicated. We should pay close attention to the changes in functions of organs, and strengthen the therapeutic strategies to support the function of organs to reduce the incidence of systemic complications. The control of the infection and the timely and effective repair of the wound are still the key points of the treatment of an extensive local radiation injury.

OBJECTIVETo investigate the effect of mesenchymal stem cell (MSC) transplantation in repairing ovarian injury in mice sensitized with porcine ovarian proteins.

METHODSWild-type female mice with ICR background (6-8 weeks old) were divided randomly into groups A, B and C (n=12). In groups B and C, the mice were treated with the total protein extract from porcine ovary to induce immunological injury of the ovary, while those in group A received no treatment. MSCs-derived from GFP transgenic mice were transplanted into the mice of group C, and equal volume of PBS was injected intraperitoneally in mice of the other two groups. PCR was used to detect GFP gene in the genomic DNA of the ovaries to assess MSCs homing in the ovary, and the reparative effect of MSCs on ovarian injury was evaluated using HE staining and TUNEL analysis.

RESULTSAfter transplantation, the MSCs could reach the injured ovaries to promote the repair of the ovarian injury, resulting also in reduced apoptosis of the granulosa cells (GCs) in the injured ovaries.

CONCLUSIONMSCs transplantation can promote the recovery of the immunological injury of the ovary in mice, the mechanism of which may involve reduced apoptosis of the GCs.

OBJECTIVETo investigate the effects of HCMV infection on phenotypes of parotid duct epithelial cells and relative mechanisms.

METHODSThe expressions of immediate early antigen of HCMV, pan cytokeratin and cathepsin D etc. were detected by immunohistochemical staining in tissues of parotid cytomegalic inclusion disease.

RESULTSCytokeratin which acts as an epithelial marker became negative while staining of Cathepsin D was intensified in parotid duct epithelial cells after infected by HCMV.

CONCLUSIONIt demonstrated that cytokeratin was lost through over-expression of Cathepsin D in parotid duct epithelial cells infected by HCMV.
