Objective To investigate the prognostic value of the changes in serum CA125 level during chemotherapy post-surgery in patients with advaneed epithelial ovarian carcinoma.Methods A retrospective analysis was conducted on 142 patients with stage Ⅲ-Ⅳ epithelial ovarian carcinoma who had primary treatment in the Cancer Center of the Sun Yat-sen University during January 1998 to December 2003.The changes in CA125 levels during chemotherapy post-surgery in patients were analyzed.The survival outcomes of patients with various levels of CA125 were studied using Kaplan-Meier method.Multivariate Cox regression model Wag used to aggess the correlations between survival and the change in CA125 level during chemotherapy and other prognostic factors.Results The 3-year overall survival(OS)was 64%,71%,and 64%respectively in patients with different pretreatment CA125 levels(≤500,>500-1500 and>1500 kU/L;P>0.05).The CA125 level was normalized(0-35 kU/L)in 77(54.2%)patients after three cycles of postoperative chemotherapy.It revealed significant differences in 3-year OS(84%vs.42%)and 5-year OS(56%vs.15%)between the patients with normalized and elevated CA125 levels(n=48)after three cycles of chemothempy(P<0.01).Multivariate analysis showed that residual tumor size>1 cm(P<0.01)and elevated CA125 after three-cycle postoperative chemotherapies(P<0.01)were two independent factors related to survival.In the subgroup of optimal cytoreduction(residual tumor size≤1 cm),the 3-year and 5-year OS rate were 88%and 64%for patients with normalized CA125 level after three cycles of chemotherapy respectively,while only 52%and 18%for patients with elevated CA125 level(P<0.01).Similarly,even in the suboptimal cytoreduction group,the 3-year and 5-year OS were also significantly increased for patients with normalized CA125 level after three cycles of chemotherapy post-surgery,as compared with patients with elevated CA125 level(74%vs.33%in 3-year OS,32%vs.13%in 5-year OS;P<0.01).Conclusions CA125 level after three cycles of chemotherapy post-surgery is an independent predictor of survival for advanced ovarian carcinoma.Whatever the patients undergo,optimal or suboptimal cytoreduction,ifthe CA125 becomes normalized after three cycles of chemotherapy,they would have more favorable prognosis than those with elevated CA125 after three cycles of chemotherapy.

Objective To investigate the correlation of serum periostin and severe degree of dilated cardiomyopathy(DCM) in children.Methods Thirty-two children with DCM from Jan.2009 to Jun.2013 in First Hospital Affiliated to Jilin University were selected as DCM group.Then these children were divided into 0-2 score group (n =6),3-6 score group (n =7),7-9 score group (n =11),and 10-12 score group (n =8) according to Ross standardization.Twenty healthy children in the same period were selected as control group.Meanwhile,the levels of serum periostin were detected by using enzyme-linked immunosorbent assay,the levels of serum creatine kinase-MB(CK-MB)were detected by adopting immunosuppressive method,while left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were observed by using uhrasonography.The data in various groups were compared and the relationship between serum periostin and ROSS,LVEF was analyzed by performing linear regression analysis.Results 1.Compared with control group,the level of serum periostin in DCM group was significantly increased,and the difference was significant (P =0.00).The serum periostin level increased with the increase of ROSS score increase,and there were significant differences among the different ROSS score groups (all P ＜ 0.05).2.Compared with control group,the level of serum CK-MB in DCM group was significantly increased,the difference was significant (P =0.00) ;while the serum CK-MB levels had no significant difference among the different ROSS score groups(all P＞0.05).3.Compared with control group,the level of LVEF in DCM group was significantly decreased,the differences was significantly(P =0.00) ; and the LVEF level decreased with the ROSS score increase,there were significant differences among the different ROSS score groups(all P ＜ 0.05).4.Compared with control group,the level of LVEDD in DCM group was significantly enlarged,and the difference was significant(P =0.00) ; but the LVEDD had no significant differences among the different ROSS score groups (all P ＞ 0.05).5.Significantly positive correlation was found between the level of serum periostin and ROSS score (r =0.742,P ＜ 0.001).There was no obvious correlation between the level of serum periostin and CK-MB(r =0.247,P ＞ 0.05).There was negative correlation between the level of serum periostin and LVEF (r =-0.424,P ＜ 0.01).Conclusions The level of serum periostin is positively correlated with ROSS score and has negative correlation with LVEF.It may provide a useful index in the assessment of symptomatic state in children with dilated cardiomyopathy.

Objective To explore the preventive effect of Bailing capsules(BL) on myocardial fibrosis in the viral myocarditis(VMC) mice models and to clarify the possible mechanism.Methods The models of VMC were established by injecting Coxsackie virus B3 (CVB3) solution into 50 BALA/C mice.The 31 mice were divided into model group(n =11),large dose BL group(n =10)and small dose BL group (n =10).At the same time the control group (n =10) was established.The mice in model group and control group were fed with water 1 mL/d,the mice in large dose BL group were fed with BL at a dose of 7.5 g/(kg · d),and the mice in small dose BL group were fed with BL at a dose of 2.5 g/(kg · d).After 60 d,the levels of angiotensin Ⅱ (Ang Ⅱ) in blood serum of mice in various groups were detected by using ELISA.Myocardium tissue of mice was stained by Masson and collagen volume fraction(CVF)was accounted.At the same time,the content of periostin mRNA and transforming growth factor β1 (TGF-[β1) mRNA in myocardium tissue of mice were detected by adopting reverse transcription(RT)-PCR.Results Compared with the control group,the levels of serum Ang Ⅱ,CVF,TGF-β1 mRNA and periostin mRNA were increased (all P ＜ 0.01) in the model group.Compared with the model group,the levels of serum Ang Ⅱ,CVF and TGF-β1 mRNA were obviously decreased in large dose BL group and small dose BL group (all P ＜ 0.05).Compared with the model group,the level of periostin mRNA was obviously decreased in large dose BL group (P ＜ 0.05),but the level of periostin mRNA in small dose BL group was not decreased obviously (P ＞ 0.05).Conclusions BL can offer some protection to myocardial fibrosis in VMC mice.The possible mechanism may be performed through inhibiting the expression of serum Ang Ⅱ and TGF-β1 in myocardium tissue to reduce the expression of periostin.

Objective To analyze the clinical features of juvenile dermatomyositis (JDM) combined with soft-tissue calcification. Methods Forty-seven patients with JDM combined with soft-tissue calcification (soft-tissue calcification group) were retrospectively analyzed, and they were contrasted with 89 patients with non-calcification (non-calcification group). Results The rates of Gotton signe, muscle contracture and joint dysfunction in soft-tissue calcification group were significantly higher than those in non-calcification group:87.23% (41/47) vs. 43.82% (39/89) and 68.09% (32/47) vs. 21.35% (19/89), and there were statistical differences (P<0.05). The dosage of glucocorticoid (conversion of prednisone measuring more than 1.5 mg/kg), rate of using immunodepressant, level of creatine kinase in soft-tissue calcification group were significantly lower than those in non-calcification group:17.02%(8/47) vs. 68.54%(61/89), 25.53%(12/47) vs. 88.76%(79/89), (566.45±240.41) U/L vs. (1 680.12±656.50) U/L, and there were statistical differences (P<0.05). Conclusions The patients with JDM combined with Gotton signe are more prone to soft-tissue calcification. The rate of muscle contracture and joint dysfunction in soft-tissue calcification patients is significantly higher than that in non-calcification patients. For the patients whose creatine kinase are not obviously elevated, they are more prone to soft-tissue calcification. Early active application of glucocorticoid and immunodepressant therapy can reduce or prevent the occurrence or development of late calcium deposition.

Objective To study the interventional effects of Candesartan Cilexetil on vascular endothelial function and expres-sions of ERK/CREB signaling pathway in rats with acute myocardial infarction.Methods 30 rats were randomized into CAN group,AMI group and Sham group.Two weeks after the treatment rats were sacrificed and blood pressure,levels of blood AngⅡ, NO and NOS,endothelial vasomotor effects of isolated thoracic aorta strips,myocardial infarctual area and the expressions of ERK mRNA and CREB mRNA in infarctual myocardium were explored.Results Blood AngⅡ levels were distinctly higher in AMI group when compared with the Sham group,while the NO and NOS level were much lower.accompanied with EDDs decreased seri-ously,and higher mRNA expressions of ERK1 and CREB in infarctual myocardium.All of the above differences were significant. After the treatment of Candesartan Cilexetil,levels of serum NO and activities of NOS were obviously higher and almost reached the similar levels to those in Sham group,additionally endothelium-dependent diastole in isolated aortic strips improved greatly.Mean-while Candesartan Cilexetil can not only increase the plasma AngⅡ,but also decrease the size of myocardial infarction and the mR-NA expressions of ERK1 and CREB in infarctual myocardium significantly.However,blood pressure in all groups was not affected. Conclusion Candesartan Cilexetil can greatly improve the disordered endothelial function developing post-AMI,decrease the size of myocardial infarction and down-regulate the mRNA expressions of ERK and CREB in myocardium of infarctual zone.And all of the above protective effects of Candesartan Cilexetil were independent on blood pressure lowering.

Objective To observe the therapeutic effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type.Methods 60 patients with cervical spondylosis of vertebral artery type were randomly divided into the treatment group and control group with 30 cases in each group. The patients of the treatment group were treated with plum-blossom needle therapy and cupping therapy combined with traction, and those of the control group only with traction. The therapeutic effects of two groups were compared.Results The total effective rate of the treatment group was 83.3 %, that of the control group was 60.0%. There was a significant difference between two groups ( P<0.05).Conclusion The effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type is superior to traction therapy alone.

BACKGROUND:Preliminary studies of our research group mainly focus on the role of nucleus of solitary tract in gastric noxious stimulation and acupuncture point, while dorsal nucleus of vagus nerve, nucleus of solitary tract and area postrema are the necessary component for vagus nerve complex, and dorsal nucleus of vagus nerve plays a crucial role in the regulation of gastric functions. OBJECTIVE:To observe the effect of acupuncture at Zusanli, Neiguan, Pishu and Shenshu acupoints on the gastric-related neurons in dorsal motor nucleus of the vagus nerve. METHODS:The gastric related neurons in dorsal motor nucleus of the vagus nerve of gastric distension rats were identified using extracellular recording technique, according to neuroelectrophysiology method. Acupuncture stimulation was given to Zusanli, Neiguan, Pishu and Shenshu for 15 seconds. The effect of body stimulation on the gastric distension related neurons in dorsal motor nucleus of the vagus nerve of rats was recorded. RESULTS AND CONCLUSION:Among the involved 24 rats, 90 neurons at paraventricular hypothalamic necleus exhibited discharge. Among the discharged neurons, 54 neurons were related to gastric distension. After acupuncture stimulation at Zusanli, Neiguan, Pishu and Shenshu, there were 44, 39, 38, 27 neurons giving a response, the reaction rate was 82%, 72%, 70%and 50%, respectively. Acupunture at different nerve segment acupoints can activate the dorsal motor nucleus of the vagus nerve to different degrees, which is involved in the regulation of gastric motility.

This study examined the current changes of human ether-a-go-go-related gene (hERG) mutation derived from a LQT2 Chinese family with a highly penetrating phenotype. Mutation was identified and site-directed mutagenesis was performed to induce the mutation in wild-type (WT) hERG. WT hERG and mutated V535M were cloned and transiently expressed in HEK293 cells. At the 48th and 72nd h after transfection, membrane currents were recorded using whole cell patch-clamp procedures. An A>G transition at 1605 resulting in replacement of V535M was identified. Compared to WT, V535M mutation significantly decreased tail currents of hERG. At test potential of -40 mV after depolarizing at +50 mV, tail current densities were 83.35±7.06 pA/pF in WT and 50.38±7.74 pA/pF in V535M respectively (n=20, P<0.01). Gating kinetics of hERG revealed that V (1/2) of steady-state inactivation shifted to negative potential in the mutant (V (1/2,V535M): -61.81±1.7 mV vs. V (1/2, WT): -43.1±0.71 mV). The time constant of recovery from inactivation was markedly prolonged in the mutant compared to WT among test potentials. V535M hERG mutation demonstrated markedly decreased tail current densities, which suggests that V535M is a new loss-of-function mutation of hERG channel responsible for LQT2.
