Objective To compare and analyze the main manifestations of HIV/ AIDS impact on marriage and family structure.Methods The relevant data of 931 HIV households and 995 non-HIV households were collected in five provinces with high HIV prevalence in China,using the method of questionnaire survey.The differences between people living with HIV/ AIDS(PLWHA)and non-HIV individuals in marriage and family structure were analyzed and compared.Results The percentage of PLWHA who were unmarried,divorced,widowed and remarried was higher than that of individuals in non-HIV households;the average size of the non-HIV households was 4.4 persons,while the size of HIV households was 4.0 persons;of the surveyed HIV households 41.1 % were stem families,while in the case of non-HIV households this percentage was lower,only 33.4 %.The rate of school enrollment among children in HIV households was lower than that in non-HIV households,while the rate of labor participation among the elderly in HIV households was higher than that in non-HIV households.Conclusion The results indicate that HIV/AIDS destroys the normal marriage among PLWHA,leading to an increased number of stem families and changes in family structure;the impact on the elderly and children in the HIV households is severe.All this means that HIV/AIDS weakens or even destroys the family function.

Objective To investigate the effects of rosiglitazone on the endothelial regeneration and neointimal formation after balloon injury in rat aortic.Methods Endothelial denudation of aorta in SD rats were performed with 2 F Fogarty balloon catheter.Male Rats were randomly divided into the sham-operated group,the control group,and the RSG group.Aortic tissues were harvested 7 days and 14 days after the injury.The endothelial regeneration rate,serum NO level,IA/MA ratio and PCNA expression index were detected.Results RSG enhanced the reendothelialization of the injured aorta determined by Evans blue staining.The RA/TA ratio on the 7~(th) day and the 14~(th) day were 38.20% and 75.20%(P

Objective The aim of our study is to differentiate left atrial from right atrial tachycardia on the basis of P wave configuration during focal atrial tachycardia (AT).Methods Thirty-three patients with focal atrial tachycardia who had undergone successful radiofrequency catheter ablation were considered for inclusion in the study . Site of origin was the left atrium in 10 patients, and right atrium in 23 patients . The surface 12-lead ECG recordings during atrial tachycardia were reviewed in all patients. We analyzed the correlativity between P wave configuration and left atrial tachycardia.Results The specificity of negative P wave in lead I and aVL that indentifed a left atrial focus was 100% and 95% respectively, but the sensitivity was only 30% and 50% respectively. The specificity and sensitivity of positive P wave in V 1 that predicted a left atrial focus was 87% and 80%,respectively.Conclusion It is possible to predict the site of origin of focal atrial tachycardia by analyzing its P wave configuration,,and may be helpful for preparation before ablation.

Objective To investigate the relationship between acute biliary pancreatitis (ABP) and anomalous pancreaticobiliary duetal union (APBDU). Methods 131 patients with ABP were enrolled to test the serum total bilirubin (TB), alanine amintransferase (ALT), aspartate amintransferase (AST), alkaline phosphates (ALP), γ-glutamyl transferase (γ-GT). All the patients received medical treatment, and then these tests were performed again. Thereafter, all the patients underwent selective surgery and intra-operative cholangiography was performed to observe the pancreaticobiliary duetal union. Results 27 patients (20.6%) with APBDU were found in 131 patients. Among them, 8 cases (29.6%) was B-P subtype (TypeⅠ), 16 cases (59.3%) was P-B subtype (TypeⅡ) , and the remaining 3 cases was mixed subtype (TypeⅢ). A significant decrease of ALT, AST, ALP, γ-GT after non-surgical treatment in both group of APBDU and NAPBDU was noted (P＜0.05). The serum levels of ALT, AST,γ-GT in APBDU patients were (71.81± 23.19) U/L, (47.85±27.87) U/L, (52.86±31.49) U/L, respectively; and in NAPBDU patients were (51.96±15.40) U/L, (40.77±16.58) U/L, (34.86±26.47) U/L. The difference was statistically significant (P＜0.05). Condusions APBDU is an important etiology of ABP.

Objective To investigate the inhibitory effect of RNA interference on the expression of Aurora A in U251 cells, and the influence on proliferation and apoptosis of U251 cells. Methods The siRNA specific for Aurora A was synthesized and transfected into U251 cells in vitro. Aurora A mRNA expression and protein content were detected by RT-PCR and Western blotting respectively. The cell proliferation and apoptosis were observed by methyl thiazolyl tetrazolium(MTT) and flow cytometry(FCM). Transmission electron microscope was used to observe the ultrastructural changes of U251 cells. Results After transfection, the expression level of Aurora A mRNA was significantly decreased(P<0.01), and the protein content of Aurora A was also obviously reduced. The inhibitory rate of cell proliferation reached up to 67.57% 72 hours after transfection, which was significantly higer than that of normal control group(P<0.01). The apoptosis rate of U251 cells was significantly increased from (3.69±0.87)% to (15.34±2.16)% (P<0.01). Under the transmission electron microscope, it was observed that the U251 cells showed typical morphologic changes of apoptosis after transfection, such as karyopyknosis, chromatin condensation and margination, intracytoplasmic vacuoles formed, and apoptotic bodies formed. Conclusion The expression of Aurora A gene can be inhibited by siRNA successfully, and it results in the suppression of cell growth and induce apoptosis of human glioma cells in vitro. Aurora A may become a new target for the gene therapy of gliomas.

With the development of natural products, the research activities on the solubilization methods of water-insoluble natural products have been carried out worldwide. Big molecular weight and poor solubility of most natural active ingredients lead to a very poor oral absorption and low bioavailability, which has extremely limited their development in pharmaceutical fields and clinical application. As a result, it is necessary to find out a suitable technique to improve the solubility and enhance the oral bioavailability of insoluble natural drugs. Based on the related references published in these years, this review introduced some new techniques to improve the solubility and bioavailability of natural drugs, including prodrugs, inclusion complex, solid dispersion, cocrystals, osmotic pump, liquisolid compacts, micronization, self-microemulsifying, nanosuspensions, lipsomes, polymeric micelles and so on, and summarized the theory, characteristics, application range, application examples, problems and development direction of each technique.

OBJECTIVETo observe the effect of electroacupuncture (EA) combined with ultraviolet therapy on herpes zoster at the acute stage and the impacts on serum interleukin 2 (IL-2), interleukin 6 (IL-6) and interleukin 10 (IL-10) in the patients.

METHODSThirty-four patients of herpes zoster were randomized into a medicine group and a combined therapy group, 17 cases in each one. In the medicine group, the intravenous drops with acyclovir injection, muscular injection with cobamamide and the topical with acyclovir ointment were applied. Additionally, TDP was radiated locally. In the combined therapy group, on the basis of the treatment as the medicine group, EA and ultraviolet therapy were supplemented. The duration of treatment was 10 days in the two groups. Before and after treatment, blister relief, incrustation time and the visible analogue scale (VAS) were recorded in the two groups. The clinical efficacy was assessed in the two groups and the levels of serum IL-2, IL-6 and IL-10 were determined in the two groups.

RESULTSIn the combined therapy group, the time of blister relief and incrustation was earlier apparently than that in the medicine group (both P<0.05). VAS score after treatment were reduced as compared with that before treatment in the two groups (both P<0.01), and the reducing amplitude in the combined therapy group was larger than that in the medicine group (P<0.01). The total effective rate was 94. 1% (16/17) in the combined therapy group, higher than 76.4% (13/17) in the medicine group (P<0.05). After treatment, IL-2 levels were increased as compared with those before treatment in the two groups (both P<0.05), the levels of IL-6 and IL-10 were reduced obviously as compared with those before treatment in the two groups (all P<0.01). After treatment, the levels of IL-6, IL-10 were reduced much more apparently in the combined therapy group as compared with those in the medicine group (both P<0.05).

CONCLUSIONEA combined with ultraviolet irradiation more rapidly and effectively relief the symptoms of herpes zoster, significantly relief pain, shorten the duration of sickness, improve the body immunity and reduce nerve injury.

BACKGROUND:Because of its advantages, Endobutton has been widely used in clinic. Currently, its shortcomings are increasingly recognized. Tightrope that overcomes the shortcomings of Endobutton has been gradualy accepted by a doctor skiled in sports injuries.
OBJECTIVE: To analyze and compare the differences in the effects of Tightrope and Endobutton in the reconstruction of the cruciate ligament.
METHODS:Totaly 60 cases of anterior cruciate ligament rupture were selected and subjected to anterior cruciate ligament reconstruction under arthroscopy, of which 30 cases were randomly assigned to reconstruction by Endobutton device and 30 cases underwent reconstruction by Tightrope device. Al operations were performed by the same surgeon. Al patients were subjected to regular functional exercise and were folowed up regularly after operation. Effects of Tightrope and Endobutton in the cruciate ligament reconstruction were evaluated by comparing various indexes in the two groups.
RESULTS AND CONCLUSION:Compared to the Endobutton fixation system, the Tightrope fixation system could shorten the operation time, reduce the length of tendon incision, and decrease the loss of bone mass in the femoral bone tunnel. There were no significant differences in the maximum knee flexion, knee joint score and Tegner movement level score between the two groups at 3 and 6 months after operation. These findings indicate that the Tightrope fixation system is superior to the Endobutton fixation system, because it is more simple and convenient to operate and has less bone loss. However, their clinical efficacy has no difference after 6 months.
