International Journal of Biomedical Engineering 2008;31(2):102-106
Penis is one of the most important components of male external genitalia.Congenital abnormalities and trauma may lead to genitourinary organ damage or default,which require reconstruction.With the development of tissue engineering(TE),penile corpora cavernosa tissue engineening has becoming the core of the penis reconstruction.Recent researches mainly focus on forming scaffolds and transplanting cells(including of endothelial cells and caveruosal smooth muscle cells). Recently, stem cell technology, gene therapy and nervous reconstructive techniques have been combined to promote the development of tissue engineering.Tissue engineering has been thought to be able to make possible the restoring and constructing of the structure and normal funetion of penile corpora cavernosa.This paper gives a review of the recent progress in associated researches on tissue engineering of the penile corpora cavernosa.
2.Application analysis of plasma Hcy,FA,VB12 levels in coronary heart disease complicating impaired glucose tolerance
International Journal of Laboratory Medicine 2014;(5):527-528
Objective To investigate the application value of the plasma homocysteine (Hcy) ,folic acid (FA) and vitamin B12 (VB12 ) levels in the patients with coronary heart disease (CHD) and CHD complicating impaired glucose tolerance (IGT) .Methods 80 triers screened by the inclusion criteria were divided into the simple CHD group (36 cases) and the CHD complicating IGT group(44 cases);70 healthy cases were taken as the controls .Hcy ,FA and VB12 levels were measured and the detection results were performed the statistical analysis .Results The Hcy level in both experimental groups were higher than that in the control group , the difference was statistically significant (P<0 .05) ,the positive rates were 94 .4% in the simple CHD group and 88 .6% in the CHD complicating IGT group respectively ;The plasma FA level in both experimental groups were lower than that in the control group ,meanwhile ,plasma Hcy level and FA level showed a negative correlation (P<0 .05);The VB12 level had no statistical differ-ence among 3 groups (P>0 .05) ,and the correlation analysis between the Hcy level in the two experimental groups with VB 12 had no statistical significance (P>0 .05) .Conclusion Plasma Hcy level in CHD and CHD complicating IGT is very high and negatively correlated with the FA level ,dynamically detecting the Hcy level has an important significance for early warning and treatment of CHD and CHD complicating IGT .
3.Clinical analysis of 160 cases with gastric carcinomas diagnosed by gastroscopy
Clinical Medicine of China 2012;28(9):939-941
ObjectiveTo study the characteristics of gastric cancer under gastroscopy.Methods From Jan.2005 to Dec.2010,160 patients were diagnosed of gastric cancer by endoscopic biopsy.Clinical data of these patients were retrospectively summarized and analyzed.ResultsThere is a high rate of HP infection [71.25% (114/160)]in the 160 cases with gastric cancer,especially in males,and the infection rate increased with age( Z =2.303,P =0.021 ).For the general morphology of gastric cancer,it was mainly Borrmann Ⅲ & Ⅳ-types for those below or equals to 35 years old(9 cases).The rate of Borrmann Ⅲ & Ⅳ types reduced and that of BorrmannⅠ& Ⅱ types increased with age.The ratio of male to female with gastric cancer was 2.26:1.However,the incidence of gastric cancer was higher in young female compared with young males.With the increase of age,the rate of prevalence of gastric cancer grew higher in males than in females ( Z =3.599,P <0.001 ).Incidence of gastric fundus-cardia and corpus cancer increased with age.Most patients had low-differentiation adenocarcinoma despite the specific sites of gastric cancer.However,the incidence of low-differentiation adenocarcinoma decreased with age(x2 =9.831,P=0.042).ConclusionThe development of gastric cancer is closely associated with HP infection.For the general morphology of gastric cancer,Borrmann Ⅲ & Ⅳ types decrease and Borrmann Ⅰ & Ⅱ types increase with age.The incidence of gastric cancer in male and that located at proximal stomach are increased with age.Moreover,the incidence of high-grade malignant gastric cancer is increased with age.
4.Effectiveness of the comfort nursing on the parents of children with laryngopharyngeal surgery
Chinese Journal of Practical Nursing 2013;(14):36-38
Objective To explore the effectiveness of comfort nursing on the parents of children with laryngopharyngeal surgery.Methods Forty-seven parents were admitted for the study,they were divided into the control group(23 cases) and the experimental group(24 cases).The control group accepted routine nursing,while the experimental group accepted comfort nursing based upon routine nursing.The SAS,SDS scores and satisfaction degree were compared between the two groups.Results After the treatment,the SAS and SDS scores of all the parents got better compared with those before treatment.The differences were obvious.While the experimental group had a better improvement than the control group.Also the satisfaction degree of the experimental group was better than that of the control group.Conclusions Comfort nursing can relieve the discomfort and anxiety of the children patients and their parents,improve the adverse emotional state of them,promote recovery of children and improve the nursing quality.

You ought to differentiate the cause, location, nature and trend of disease, for chronic nephritis. The causes inducing or worsening the disease can be exopathy, as well as internal injury, pathological substance and drug pathogenic factors; while the deficiency of Qi blood Yin Yang of organs is often the internal basis of the disease. The location mainly concerns lung, spleen, liver and kidney, esp. kidney. The nature is deficient root and excessive superficiality; its general trend mostly appears Qi deficiency-both deficiency of Qi and Yin(blood)- both deficiency of Yin and Yang, a discipline of gradual development, and wind, wetness, heat, stasis, sputum and toxin worsen the development of the disease.

Chronic nephritis is a common clinical refractory disease,with complex mechanism,hard and long to cure.The TCM treatment in Internal Classic has key guideline meaning and is proved in modern TCD pharmacology,such as "kidney governs spleen,spleen holds nutrition,dislikes dampness and governs outer guard" of spleen picture,etc.

Academic Journal of Second Military Medical University 1981;0(03):-
Objective:To investigate the effects of ?-lipoic acid on cell proliferation and expression of intercellular adhesion molecule1(ICAM-1) induced by high glucose(HG) in rat mesangial cells(MCs).Methods: Rat mesangial cells were co-cultured with normal glucose(5.6 mmol/L,NG group),high glucose(25 mmol/L,HG group),and HG+?-lipoic acid(50,100,200,300 ?mol/L)for 12,24 and 48 h,respectively.Cell proliferation was assessed by MTT;the levels of ICAM-1 in the supernatants were determined by enzyme-linked immunosorbent assay(ELISA);and ICAM-1 mRNA expression was measured by semi-quantitative RT-PCR.Results: ?-lipoic acid at 50-300 ?mol/L inhibited the proliferation of MCs.Semi-quantitative RT-PCR showed that ?-lipoic acid(100 and 200 ?mol/L)significantly inhibited the high glucose-induced increase of ICAM-1 mRNA((P

Journal of Chongqing Medical University 2007;0(07):-
Objective:To discuss the influence of organic selenium on the immune effect of Bacille Calmette-Guerin(BCG). Methods:C57BL6/J mice were randomized into 4 groups:"BCG+Se"mice group were intracutaneously inoculated with BCG and orally fed with yeast-based selenium(Se);BCG mice group were immunized with BCG intracutaneously;Se mice group were im- munized with normal sodium and fed orally with Se;control mice group were immunized with normal sodium and fed orally water without Se.The mice were sacrificed after 4weeks or 8weeks to isolate the spleen mononuclear cells.T lympholeukocyte proliferation testing(stimulation index,SI),cytotoxic T lympholeukocyte(CTL)function testing as well as levels of IL-2 and IFN-?and mRNA levels of granzyme B and perforin were employed to assess the effect of vaccine for Mycobacterium tuber- culosis.They were determined by MTT assay,ELISA assay and RT-PCR,respectively.Results:The levels of 6 detected items in"BCG+Se"group and BCG group were significantly different from those in the control group(P
