ObjectiveTo investigate the influence of transverse and longitudinal lower segment caesarean section on the outcome of newborn, postpartum haemorrhage and ratio of complications in placenta previa. MethodsPlacenta previa with lower segment transverse caesarean section( 117 cases) were taken as control group, meanwhile, the lower segment with longitudinal section (142 cases ) as experimental group. Their operational complications, amount of bleeding during and after operation and outcome of the perinatal period were analysed.Results No significant difference in age, parities, gestational weeks, the types of the placenta praevia and the locus of placenta between the two groups were found( P>0.05), while there were significant difference in the amount of bleeding during and after operation, the need of using gauze ribbon to stop bleeding, section splitting and rate of hysterectomy after caesarean section(P<0.01). ConelusionLower segment longitudinal caesarean section in placenta praevia not only shows less bleeding during operation and lower rate of postpartum haemorrhage, but also avoids using gauzes to stop bleeding and causes lower rate of hysterectomy after caesarean section, so it can be the first choice when determining the style of section in placenta praevia.

Myoepithelial carcinoma is a rare malignant tumor. The primary site of this tumor is the salivary glands. With the rapid ad-vancement in immunohistochemical examination and pathological examination, the number of clinical cases of the most common type of myoepithelial carcinoma of the salivary glands, as well as rare primary sites of myoepithelial carcinoma, reported in the litera-ture has increased. Based on related cases reported in the literature, various studies worldwide, and our personal practical experience, this article summarized advancements in the research on myoepithelial carcinoma, including etiology, pathology, clinical characteris-tics, diagnosis, and treatments, as well as myoepithelial carcinoma features of various rare primary sites. This article aims to provide useful evidence for oncologists in diagnosing and treating myoepithelial carcinoma.

Objective To investigate the effect of different pressures of hyperbaric oxygen (HBO) treatment on neuropathic pain (NP) in rats.Methods Twenty-four healthy male Sprague-Dawley rats were randomly divided into 4 groups (n =6 each):sham operation group (group S),NP group,treatment with HBO at 2.0 atmosphere absolute group (group HBO2.0) and treatment with HBO at 2.5 atmosphere absolute group (group HBO2.5).The animals were anesthetized with intraperitoneal 5 ％ chloral hydrate 300 mg/kg.NP was induced by chronic constrictive injury.The left sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1-mm intervals with 4-0 silk thread.After the rats were placed in the HBO chamber,the pressure was increased at a rate of 10 kPa/min until the desired pressure was reached,and then the pressure was maintained at this level for 60 min.The pressure was then decreased at a rate of 10 kPa/min until the normal pressure was reached.HBO treatment was performed once a day for 5 consecutive days starting from 1st day after operation in groups HBO2.0 and HBO2.5.While the rats were only placed in the HBO chamber and stayed for 100 min in groups S and NP.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 0,1and 2 h after leaving the HBO chamber (T0.2).Results Compared with group S,MWT was significantly decreased and TWL was shortened in group NP (P ＜ 0.05).Compared with group NP,MWT was significantly increased and TWL prolonged at T1 during the treatment (P ＜ 0.05),while no significant change was found in MWT and TWL at T2 during the treatment in groups HBO2.0 and HBO2.5 (P ＞ 0.05).There was no significant difference in MWT and TWL at each time point during the treatment between groups HBO2.0 and HBO2.5 (P ＞ 0.05).Conclusion Treatment with different pressures of HBO can reduce NP in rats,but the change in pressure dose not affect the analgesic efficacy.

The experiment was conducted to examine the effect of copper toxicity on the peripheral blood T-lymphocyte using the flow cytometry(FCM) and ANAE.180 one-day-old Avian broilers were divided randomly into three groups,and fed diets as follows:(1)Controls(Cu 11.97 mg/kg diet) and (2)copper toxic(Cu 650 mg/kg diet,copper toxic group Ⅰ;Cu 850 mg/kg diet,copper toxic group Ⅱ) for six weeks.The ANAE positive ratios of the peripheral blood T-lymphocytes were much lower in the two copper toxic groups than in control group from 1 to 6 weeks of age(P＜0.05 or P＜0.01).Also,there was significant difference between copper toxic groups Ⅰ and Ⅱ at 1,3,5 and 6 weeks of age(P＜0.05 or P＜0.01).CD+4 T cell numbers reduced from 2 to 6 weeks of age in both copper toxic group Ⅰ and copper toxic group Ⅱ as compared with those of control group(P＜0.05 or P＜0.01).At the same time,there was significant difference between copper toxic groups Ⅰ and Ⅱ at 6 weeks of age(P＜0.05).But the numbers of CD+8 T cell were not varied from 2 to 6 weeks of age in copper toxic groups Ⅰ and Ⅱ in comparison with those of control group(P＞0.05).The CD+4/CD+8 ratio was lower from 2 to 6 weeks of age in copper toxic groups Ⅰ and Ⅱ than in control group.The results showed that copper toxicity could suppress the development of T-lymphocytes and reduce the peripheral blood T-lymphocyte populations.Potential mechanisms underlying these observations are also discussed.

ObjectiveTo determine the effect of telmisartan on the levels of serum adiponectin and C-reactive protein(hs-CRP)in elderly hypertensive patients with unstable angina pectoris. MethodsOne hundred and twenty elderly hypertensive patients with unstable angina pectoris were randomized into two groups, telmisartan(n=60) and perindopril(n=60) groups.The levels of hs-CRP,adiponectin, lipid factors, fasting plasma glucose (FPG), insulin and insulin sensitivity index (ISI) were measured before and 6 months after telmisartan and perindopril treatments.ResultsAt the end of 6 months, the telmisartan group showed more reduction in plasma levels of hs-CRP and more increment in serum adiponectin concentrations and ISI significantly. The frequency of cardiovascular events was significantly lower in the patients of the telmisartan group than that of the perindopril group.ConclusionsCompared with perindopril, telmisartan significantly decreases plasma levels of hs-CRP and increases serum adiponectin concentrations in elderly hypertensive patients with unstable angina pectoris. It also significantly decreases the frequency of cardiovascular events in these patients.
