Chinese Journal of Practical Surgery 2001;21(3):145-146
ObjectiveTo study the hemodynamic changes in combined portoazygous devascularization and mesocaval shunt for treating portal hypertension and the effect of this operation. Methods100 cases of portal hypertension who received this combined operation from 1980 to 1995 were analyzed retrospectively. ResultsFree portal pressure(FPP)after shunt decreased to 1.92 kPa,which decreased portal pressure and preserved with (2.46 ± 0.30)kPa to maintain a good inflow to the liver and the encephalopathy rate was lowered. There was no death, and the effect was satisfactory. 5~15 years follow-up of 89 cases showed no rebleeding,with only 5% of encephalopathy and 15% of total mortality. Among them, 13 cases of Child C died of late-stage hepatopathy, such as liver failure, liver cancer and hepatorenal syndrome,with 94.5% of 5-year survival rate and 68.5% of 10-year survival rate. ConclusionThis combined operation is characterized by complete devascularization of sustaining varices and distal partial shunt with logical diameter. A perfect combination of both shunt and devascularization, it's one of the best choices currently available for treating portal hypertension in China.
5.Advances in the research of gene therapy for chondral lesions
International Journal of Biomedical Engineering 2009;32(3):172-176
Cartilage injury has a very limited capacity of recovery by itself due to the lack of blood vessel in cartilage tissues. Current studies indicate that many kinds of cytokines have the function of promoting cartilage formation or repairing the injured cartilage with cartilage-like tissues. Cell-mediated transfer of the respective genes may ideally combine the supply of a chondrogenic cell population with the production of certain factors se-creted from the lesion and to promote the repairing of the lesion, which is considered the best treatment. Gene therapy based on this technology has developed rapidly in recent years. This review aims to summarize some of the development of the research in the field.

IL-17,as a pro-inflammatory cytokine,is one of the early initiation factors of the inflammato-ry response induced by T cells.It can induce and regulate multiple immune responses.Recent studies have re-vealed that myeloid neutrophils,macrophage,mast cell and other innate immune cells all can secrete large a-mount of early responding IL-17 in organs suffering ischemia/hypoxia,and in turn can activate,amplify and re-cruit neutrophils to the reperfusion-damaged tissue to release large amount of free radicals and lysozyme that cause IRI.Researchers have also provided evidence that appropriate administration of anti-IL-17 mono-antibody to neutralize IL-17 during early reperfusion stage would reduce the tissue damage.The purpose of this review is to summarize the research progress of the effects of IL-17 produced by innate immunocyte on organ reperfusion injury.

Objective To study the changes of intrapartum cesarean rate, cesarean indications and pregnancy outcomes after the new partogram applied. Methods Totally 3 290 pregnant women trying to vaginal delivery which were managed according to the new partogram in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from August to October in 2014 (new partogram group) were involved;2 987 pregnancy women trying to vaginal delivery from May to July in 2014 which were managed according to the old partogram (old partogram group) were involved as control. The intrapartum cesarean rate, cesarean indications and the pregnancy outcomes between the two groups were analyzed. Results The rate of intrapartum cesarean delivery was 8.50%(254/2 987) in old partogram group, and was significantly higher than that in new partogram group (6.2%, 204/3 290;P<0.01). Cesarean indications in old partogram group included 18 labor protraction (7.1%, 18/254), 82 labor arrest (32.3%, 82/254), 44 relative cephalopelvic disproportion (17.3%, 44/254), 80 fetal distress (31.5%, 80/254), 23 intrauterine infection (9.1%, 23/254) and 7 cesarean delivery on maternal request (CDMR;2.8%, 7/254) . Cesarean indications in new partogram group included 33 labor arrest (16.2%, 33/204), 71 relative cephalopelvic disproportion (34.8%, 71/204), 73 fetal distress (35.8%, 73/204) and 22 intrauterine infection (10.8%, 22/204), 5 CDMR (2.5%, 5/204). There were no significant differences in incidence of asphyxia neonatorum and puerperal morbidity (P>0.05), but the incidence of postpartum hemorrhage in new partogram group was higher than the old partogram group [6.9% (14/204) versus 1.6% (4/254), P<0.05]. Conclusion After the new partogram applied, the rate of intrapartum cesarean delivery is significantly decreased, but the incidence of postpartum hemorrhage is increased.

To evaluate the effects and safety of laparoscopic vertical banding gastroplasty (LVBG) in morbid obese subjects. The clinical data related to the metabolism of glucose, lipids and obesity in 26 obese Chinese patients with LVBG one year before and after the surgery were analyzed. The results showed that 1 year after LVBG, there was a reduction of 22.98?14.27kg in body weight, 9.31?5.13kg/m 2 in BMI, and a reduction of 47.19%?31.17% of body over-weight (EWL%) in these patients. BMI, waist, waist hip ratio, systolic blood pressure, fasting insulin, insulin resistance based on HOMA, triglyceride, cholesterol/HDL, ALT and blood creatine were decreased with reduction of body weight and BMI after LVBG. Changes in BMI and EWL% were significantly correlated with those of fasting insulin and insulin resistance. It is suggested that LVBG is effective and safe for reducing body weight and improving metabolism in the markedly obese patients.
