OBJECTIVETo investigate the protective effects on allografts and the possible mechanism of adeno-associated heme-oxygenase-1 (AdHO-1) gene therapy against chronic rejection injury.

METHODSEx vivo AdHO-1 gene therapy was performed in vascular and renal transplantation models. The structure and function, the expression of therapeutic genes and proteins, and the immune modulation were analyzed.

RESULTSAdHO-1 gene therapy protected renal transplant against chronic rejection, but the effect was not as remarkable as that in vascular transplant. The transfected empty vehicle aggravated chronic rejection damage in renal transplantation. AdHO-1 decreased the infiltration of macrophages and CD4(+) T cells.

CONCLUSIONSAdHO-1 gene therapy can lessen damage of chronic rejection in allografts. It plays roles by protecting transplants, down-regulating immune response and inducing immune deviation.

OBJECTIVETo analyze the effectiveness and safety of controlled-release dinoprostone insert for term labor induction in the Pearl River Delta of Guangdong province.

METHODSTwenty hospitals using controlled-release dinoprostone insert for term labor induction in the Pearl River Delta of Guangdong province were stratified into provincial hospitals and municipal hospitals, and three hospitals of each level were selected as research units. According to the inclusion and exclusion criteria, 1390 pregnant women receiving term labor induction using controlled-release dinoprostone insert were retrospectively analyzed to evaluate the the effectiveness and safety with another 957 pregnant women with induced abortion using oxytocin as the control group.

RESULTSCompared with the control group, the controlled-release dinoprostone insert group showed a significantly longer length of the latent phase of labor (4.06∓2.65 vs 3.20∓2.08 h, P=0.003, 95%CI [0.182, 0.920]) and shorter lengths of the active phase (1.73∓1.32 vs 2.22∓1.75 h, P=0.000, 95%CI [-0.795, -0.363]) and the second stage of labor (0.49∓0.37 vs 0.54∓0.43 h, P=0.003, 95%CI [-0.137, -0.028]). No significant differences were found in the length of the first stage of labor, the vaginal delivery rate, adverse reactions, or fetal outcomes between the two groups.

CONCLUSIONControlled-release dinoprostone insert is effective and safe for labor induction at term.

Objective To investigate the prevalence and major risk factors of peripartum thromboembolic disease in different regions of Guangdong province.Methods Data from 169 218pregnant women in different regions of Guangdong province from January 2005 to June 2010 were analyzed retrospectively.The prevalence and epidemiological characteristics of thromboembolic disease during pregnancy or puerperium were investigated.Results Of the studied population,( 1 )20 l cases ( 1.3‰ ) suffered from thromboembolic disease during pregnancy or puerperium including 128 cases of deep vein thrombosis (DVT),68 cases of cerebral venous thrombosis (CVT) and 5pulmonary embolism,the prevalence rates were 0.8‰,0.4‰,and 0.02‰ respectively.(2) Risk factors in different regions showed that,in the Pearl River Delta area,the major risk factors for DVT would include previous or family history of thrombosis,pregnancy complications,with medically involved diseases,prolonged bed rest and pregnancy weight gain ＞ 15 kg etc.While in castern,western,northern parts of Guangdong,the major risk factors for DVT would include pregnancy weight gain ＞ 15 kg,prolonged bed rest,preeclampsia,cesarean section and complications during pregnancy.In Pearl River Delta region,the major risk factors for CVT would include eclampsia,preeclampsia,pregnancy complications,prolonged bed rest ＞3 days,past history or family history of thrombosis.While eclampsia,preeclampsia,advanced age or younger age,pregnancy weight gain ＞15 kg,complications during pregnancy were the major risk factors for CVT in the eastern,western or northem parts of Guangdong.Conclusion Prevalence and major risk factors of peripartum thromboembolic disease in different regions of Guangdong were different.It was crucial to take effective measures in pregnant women with different epidemiological characteristics and risk factors to prevent and reduce the incidence of peripartum thromboembolic disease.

PURPOSE: Rapid decompressive craniectomy (DC) was the most effective method for the treatment of hypertensive intracerebral hemorrhage (HICH) with cerebral hernia, but the mortality and disability rate is still high. We suspected that hematoma puncture drainage (PD) + DC may improve the therapeutic effect and thus compared the combined surgery with DC alone. METHODS: From December 2013 to July 2019, patients with HICH from Linzhi, Tibet and Honghe, Yunnan Province were retrospectively analyzed. The selection criteria were as follows: (1) altitude ≥1500 m; (2) HICH patients with cerebral hernia; (3) Glascow coma scale score of 4-8 and time from onset to admission ≤3 h; (4) good liver and kidney function; and (5) complete case data. The included patients were divided into DC group and PD + DC group. The patients were followed up for 6 months. The outcome was assessed by Glasgow outcome scale (GOS) score, Kaplan-Meier survival curve and correlation between time from admission to operation and prognosis. A good outcome was defined as independent (GOS score, 4-5) and poor outcome defined as dependent (GOS score, 3-1). All data analyses were performed using SPSS 19, and comparison between two groups was conducted using separate t-tests or Chi-square tests. RESULTS: A total of 65 patients was included. The age ranged 34-90 years (mean, 63.00 ± 14.04 years). Among them, 31 patients had the operation of PD + DC, whereas 34 patients underwent DC. The two groups had no significant difference in the basic characteristics. After 6 months of follow-up, in the PD + DC group there were 8 death, 4 vegetative state, 4 severe disability (GOS score 1-3, poor outcome 51.6 %); 8 moderate disability, and 7 good recovery (GOS score 4-5, good outcome 48.4 %); while in the DC group the result was 15 death, 6 vegetative state, 5 severe disability (poor outcome 76.5 %), 4 moderate disability and 4 good recovery (good outcome 23.5 %). The GOS score and good outcome were significantly less in DC group than in PD + DC group (Z = -1.993, p = 0.046; χ CONCLUSION PD + DC treatment can improve the good outcomes better than DC treatment for HICH with cerebral hernia at a high altitude.
