Background and purpose:Fallopian tube carcinosarcoma is a rare malignant tumor that is prone to metastasis and recurrence. Patients with the malignancy often have poor prognosis. This paper retrospectively analyzed the clinical manifestation, pathology, treatment and prognosis of fallopian tube carcinosarcoma.Methods:The clinical manifestations, pathological features, treatment and survival time of 7 cases of fallopian tube carcinosarcoma were retrospectively analyzed.Results:The most common symptoms of 7 cases of fallopian tube carcinosarcoma were irregular vaginal bleeding (4/7, 57.1%). Among 7 cases, one case was stageⅠa, 1 stageⅡa, 1 stageⅡb, 1 stageⅢb, and 3 stageⅢc. Four cases (57.1%) were heterologous and found to have cartilage components whereas 3 cases (42.9%) were homologous. Seven cases were performed with tumor volume reduction surgery, and 6 cases with chemotherapy, while no one received radiotherapy. Five patients survived and 2 were dead. The survival time of 3 patients was more than 5 years. The longest survival time to the end of the follow-up was 114 months.Conclusion:The pathological examination is the diagnostic means of fallopian tube carcinosarcoma. The prognosis of the patients with the pathological characteristics of the homologous is better than that of the heterologous. Satisfactory reduction of tumor, postoperative chemotherapy with adequate TP regimen, combined with systemic chemotherapy and intraperitoneal chemotherapy may be an effective treatment for fallopian tube carcinosarcoma.

Objective To explore the linearic regularity of airways′ spasm and spasmolysis in asthmatic patients,and provide theory bases for clinic treatment.Methods After regular bronchodilation test,the pulmonary function in(16 asthmatic) patients and 14 volunteers were examined 15 min,30 min, 1 h,2 h and 4 h later,respectively.The indexes included forced vital capacity(FVC),forced expiratory flow in one second(FEV_1),peak expiratory flow(PEF),maximal midexpiratory flow(MMEF),expiration of 50% FVC(V_(50)) and expiration of 75% FVC(V_(25)).Results 2 h after bronchodilation test,the big airways dilated completely(P

AIM: To investigate the effects of berberine (Ber) on ion transport and hypersecretion induced by cholera toxin(ChT) in ileum and its mechanism. METHODS: Ussing Chamber technique was used to measure the potential difference(PD), short-circuit current(SCC), and the resistance(R) in isolated guinea-pig ileum. The effects of Ber on PD, SCC and R in glucose Tyrode solution or glucose-free Tyrode solution were examined. The secretory diarrhoea model was made by ChT to investigate the effects of ChT and ChT+Ber on PD, SCC and R. RESULTS: (1)The PD and SCC were decreased in glucose Tyrode solution by the Ber added in mocosal side or in serosal side in ileum of normal guinea-pig and which was with secretory diarrhoea ( P

Objective To investigate the effects of maternal behaviors in the rats with neuropathic pain (NP) on emotions of offspring rats and the relationship with DNA methylation in the amygdala.Methods Forty-eight healthy adult Sprague-Dawley rats (24 males and 24 females),weighing 200-250 g,were used in the study.Twelve female and 12 male rats were randomly selected,and NP was induced by chronic constriction injury (CCI).Each female rat was mated with one male rat at 10 days after CCI.Fortyeight F1 generation rats of maternal rats with NP were randomly divided into 2 groups (n =24 each) using a random number table:NP1 group and NP2 group.Forty-eight F1 generation rats of normal maternal rats were randomly divided into 2 groups (n=24 each) using a random number table:S1 group and S2 group.The F1 generation rats were cross-fed immediately after birth between group NP2 and group S2,and fed by their own mother rats in NP1 and S1 groups.All the offspring rats were fed to 21 days after birth by the maternal rats selected,and separately fed to 30 days after birth,and then subjected to behavioral testing.Retrieving and licking pups were recorded after delivery in maternal rats to evaluate the maternal behaviors.The mechanical and thermal paw withdrawal thresholds were measured in the offspring rats.Elevated plus maze and open field tests were conducted to detect anxiety and depression behaviors in the offspring rats.At 1 day after completion of behavioral testing,the expression of DNA methyltransferase 1 (DNMT1) and DNA methyltransferase 3a and 3b in the amygdala was detected by Western blot analysis.Results Compared with S1 or S2 groups,the latency to lick pups,latency to retrieve pups,and total retrieval time were significantly prolonged,and the total time spent licking pups was significantly shortened in NP1 group or NP2 group (P＜0.05 or 0.01).There was no significant difference in the mechanical and thermal paw withdrawal thresholds in the offspring rats between the four groups (P＞0.05).Compared with group S1,the ratios of time spent in the open arm to the closed arm and of time spent in the central square to the peripheral square were significantly decreased,DNMT1 expression in the amygdala was significantly up-regulated,and the total DNA methylation was increased in the offspring rats in S2 and NP1 groups (P＜0.05).Compared with group NP2,the ratios of time spent in the open arm to the closed arm and of time spent in the central square to the peripheral square were significantly decreased,DNMT1 expression in the amygdala was significantly up-regulated,and the total DNA methylation was increased in the offspring rats in S2 and NP1 groups (P＜0.05).Conclusion Decreased maternal behaviors in the rats with NP results in negative emotions including anxiety and depression in the offspring rats,and the mechanism is related to increased DNA methylation in the amygdala of the offspring rats.

AIM: To observe the role of c-fos in the protection by cholecystokinin-octapeptide (CCK-8) against pulmonary artery smooth muscle cell (PASMC) injury induced by lipopolysaccharide (LPS). METHODS: The ultrastructure of PASMC was observed under transmission electron microscope (TEM). MDA content,LDH release and the rate of trypan blue in PASMC were measured,and immunocytochemistry technique was adopted to observe the c-fos protein expression. RESULTS: The TEM results showed significant PASMC structural injury in LPS group and alleviated structural changes in LPS+CCK-8 group. CCK-8 reduced the increase in the rate of trypan blue uptake,MDA content and LDH release in PASMC induced by LPS. LPS lightly increased c-fos protein expression,which was enhanced by CCK-8. CONCLUSION: CCK-8 attenuated the injury of PASMC induced by LPS,which may be concerned with the increase in c-fos protein expression.

OBJECTIVE To discuss the related factors of toxigenic Helicobacter pylori(Hp) infection among adult population in Futian District,Shenzhen.METHODS A total of 1164 adults who had health examination in community centers were investigated through questionnaire and detected Hp antibodies.RESULTS The Hp and toxigenic Hp infection rates among them were 45.5% and 14.2%.Among them 46.3% and 14.8% were in males,and 44.7% and 13.4% in females.People less than 60 years old had higher incidence of Hp and toxigenic Hp,but decrease in people rnore than 60 years old.Hp and toxigenic Hp infection rate in married people were higher than those of unmarried.In workers,farmers and doctors were higher than staff and other occupations.The incidence were higher in drinking raw water than those drinking boiling water.in taking antibiotics before serologic examination were lower than no taking antibiotics;in peptic ulcer disease were higher than in no peptic ulcer disease;in per capita housing area over 6 m2 were higher than less 6 m2.CONCLUSIONS The infection rates of Hp and toxigenic Hp among our adult population are low,and positively correlated with age but gender.The social environment such as living condition,economic income,culture level and residential density maybe influence the infection of Hp.The route of transmission of Hp is unknown yet,water perhaps is an important dissemination medium.

Objective:To make a self-made fall/fall protection cover and explore its application effect.Methods:Five high-risk fall wards in Songjiang District Central Hospital were selected as the pilot wards. According to the length of stay, 80 elderly patients treated from June to December in 2020 were selected as the control group and 80 patients treated from January to June in 2021 were selected as the experimental group. The control group was treated with routine fall prevention / bed falling intervention measures, and the experimental group was treated with self-made fall prevention / bed falling protective cover on the basis of routine intervention measures. The incidence of falling/falling bed, physical restraint rate, comfort and satisfaction of hospitalized patients were compared between the two groups.Results:During the study period, there was no fall in the experimental group and one patient in the control group. The incidence of fall was 0.125 ‰ (1/8 000) ( t=-0.06, P>0.05). The rate of physical restraint was 8.75%(875/10 000) in the experimental group, and 26.25%(2 100/8 000) in the control group, the difference was statistically significant( t=-5.51, P<0.05). The scores of comfort and satisfaction were (93.43 ± 13.01), (134.50 ± 15.56) points in the experimental group and (81.68 ± 13.41), (111.88 ± 16.22) points in the control group, the differences were statistically significant ( t=8.03, 12.92, both P<0.05). Conclusions:The self-made fall / fall protection cover can reduce the utilization rate of physical constraints, improve the overall comfort of patients, improve patients′ satisfaction.It has clinical promotion value.

Objective To systematically evaluate the therapeutic effect of pulse high volume hemofiltration (PHVHF) for treatment of patients with sepsis. Methods Databases such as PubMed in American National Medical Library, Holland medical abstract Embase, the Cochrane Library, China National Knowledge Internet (CNKI), China Biological Medical Literature Database (CBM), VIP, WanFang databases, etc. were searched by computer to retrieve randomized controlled trials (RCTs) on PHVHF for treatment of patients with sepsis, and the retrieval time ranged from the creation of database to March 25, 2017. Both groups of patients received conventional treatments, including antibiotics, fluid resuscitation, vasoactive agents as well as other organ function support treatments to maintain the basic vital signs stable. Patients in PHVHF group received PHVHF besides conventional treatment, while the patients in control group received conventional treatment or any other continuous renal replacement therapy (CRRT) mode with PHVHF excluded. The literatures accepted should at least include one of the following changes of outcome indicators, such as overall mortality, the levels of inflammatory mediators eliminated, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score, service life of filter, amount of replacement fluids used. Two researchers independently screened literatures, extracted data, and assessed the methodological quality of included studies. Meta-analysis was conducted by using RevMan 5.3 software and the publication bias was evaluated by visually inspecting funnel plots. Results A total of 11 RCTs involving 410 patients met eligibility criteria, of which 204 patients in the PHVHF group and 206 patients in the control group. In the control group 5 RCTs used other CRRT modes, and 6 RCTs applied the conventional therapy. Meta-analyses showed that interleukin-6 [IL-6, standard mean difference (SMD) = -0.80, 95% confidence interval (95%CI) = -1.56 to -0.06, P = 0.04], tumor necrosis factor-α (TNF-α, SMD = -0.78, 95%CI = -1.33 to -0.23, P = 0.006), APACHE Ⅱ scores [mean difference (MD) = -3.80, 95%CI = -5.08 to -2.52, P < 0.000 01] were obviously lower than those in control group, but no significant statistical significance in mortality was seen between the two groups [relative risk (RR) = 0.72, 95%CI = 0.49 - 1.07, P = 0.10]. Further subgroup analyses suggested that compared with conventional treatment group, in PHVHF group mortality (RR = 0.40, 95%CI = 0.16 - 0.95, P = 0.04), IL-6 (SMD =-1.87, 95%CI = -3.58 to -0.16, P = 0.03), TNF-α (SMD = -1.32, 95%CI = -2.24 to -0.40, P = 0.005), and APACHE Ⅱscore (MD = -4.29, 95%CI = -6.02 to -2.56, P < 0.000 01) were significantly decreased; however, only a significantly decreased APACHE Ⅱ score (MD = -2.95, 95%CI = -4.56 to -1.35, P = 0.000 3) was observed in PHVHF group compared to that in subgroup of other CRRT modes. Conclusions Compared with using conventional therapy alone, using PHVHF combined with conventional therapy for treatment of patients with sepsis can more effectively improve their prognosis, and PHVHF can be the efficacious alternatives of other CRRT modes especially the HVHF. However, due to the limited quantity and quality of the included studies, further high-quality, multicenter, large-scale RCTs are needed to verify the above conclusion.
