Precision diagnosis of a full-term pregnancy with hydatidiform mole based on postnatal short tandem repeat DNA genotyping: a case report / 中华围产医学杂志

We describe a case of spontaneous conception following ovarian stimulation, in which a singleton pregnancy was revealed by ultrasound at 17 gestational weeks, with a multi-cystic "honeycomb" pattern in part of the placenta. With close monitoring, the patient delivered a healthy male neonate through cesarean section at 38 gestational weeks. The clinical findings, combined with ultrasound, laboratory, pathological, and immunohistochemistry examination, and short tandem repeat genotyping, confirmed a twin pregnancy consisting of a complete mole and coexisting fetus. No obvious abnormalities were found in the mother or the boy during a four-and-a-half-year's follow-up.

Application of Chinese medicine in enhanced recovery around surgery in perioperative period of laparoscopic anterior resection for rectal cancer patients / 国际中医中药杂志

Objective:To explore the application of enhanced recovery around surgery (CMERAS) by integrated Traditional Chinese Medicine & western medicine in perioperative period of laparoscopic anterior resection for rectal cancer patients.Methods:100 patients with rectal cancer who were treated by laparoscopic anterior resection in Shuguang Hospital from July 2017 to July 2019 were divided into two groups with random number table method, 50 patients in each group. The control group received enhanced recovery after surgery (ERAS) perioperative treatment and the observation group received CMERAS perioperative treatment. Both groups were treated for 7 days. The degree of intestinal cleansing during the operation and postoperative rehabilitation quality were observed of the two groups, including the time of first exhaust, hospitalization time and the incidence of complications. Serum CRP level was detected by immunoturbidimetry, serum IL-6 level was detected by chemiluminescence immunoassay and peripheral blood CD4, CD8 and CD4/CD8 were detected by flow cytometry. Adverse reactions were recorded for the two groups.Results:There was no significant difference in the degree of intestinal cleansing between the two groups during operation ( Z=-1.140, P=0.254). The first postoperative exhaust time in the observation group (29.7 ± 4.6 h vs. 36.1 ± 3.8 h, t=7.590) was earlier than that of the control group, the hospitalization time (4.2 ± 0.5 d vs. 4.7 ± 0.6 d, t=4.379) was less than that of the control group, and the incidence of complications [8.0% (4/50) vs. 30.0% (15/50), χ2=6.498] was lower than that of the control group ( P<0.01). On the third day after the operation, serum CRP (11.84 ± 4.69 mg/L vs. 23.63 ± 5.04 mg/L, t=12.106) and IL-6 (34.31 ± 5.93 ng/L vs. 44.39 ± 8.81 ng/L, t=6.714) in the observation group were lower than those in the control group ( P<0.05). CD4 levels [(37.74 ± 7.28)% vs. (33.55 ± 5.07)%, t=-3.344], CD4/CD8 ratio (1.36 ± 0.27 vs. 1.13 ± 0.22, t=-4.920) were higher than those in the control group ( P<0.01), and CD8 levels [(28.04 ± 4.68)% vs. (30.22 ± 4.04)%, t=2.487] was lower than that of the control group ( P<0.05). There were no adverse reactions in two groups during the treatment. Conclusion:CMERAS could promote the perioperative recovery of patients with rectal cancer if treated with laparoscopic anterior resection and fewer complications would occur.

A Community-Based Addiction Rehabilitation Electronic System to Improve Treatment Outcomes in Drug Abusers: Protocol for a Randomized Controlled Trial.

Introduction: Relapse is very common in drug abusers and contributes to a series of negative consequences. Effective addiction treatment exists but there are some problems in the implementation process. Mobile health (mHealth) offers a potential solution to improving recovery outcome for drug abusers in the community. The research team developed a community-based addiction rehabilitation electronic system (CAREs). The primary aim of this study is to explore whether the integrated rehabilitation based on program CAREs promotes drug abusers to keep abstinence. The secondary aim is to evaluate the impact of CAREs on interaction between drug users and service providers, and on addiction-related physical and social functions. Method and analysis: A randomized controlled trial (RCT) will be conducted. The study is a superiority trial with parallel group design. Seventy drug abusers who are newly ordered to undergo community rehabilitation will be recruited from the community in Shanghai. Participants will be 1:1 randomly assigned to receive integrated community rehabilitation by using CAREs or only receiving routine community rehabilitation for 6 months. Corresponding social workers will provide service and monitor their drug use behavior in accordance with the routine work-flow. Outcomes will be assessed at baseline and in the 6th month. The primary outcome is the performance on illicit drug urine test which will be carried out regularly twice per week during the study period. Secondary study outcomes include longest duration of sustained abstinence, days that participants interact with social workers, and the decrease rate of addiction-related issues severity index. Chi-square tests and ANOVAs will be used to compare characteristics of the members of the two groups. GEE will be used to compare the seven dimensions scores of the ASI between groups. Discussion: The study provides evidence for the feasibility and effectiveness of the "CAREs" system through comparing the results of the intervention group with the control group. This paper describes the design and methodology of the study. Ethics and dissemination: The Ethical Board of SMHC approved the study protocol. All participants will present for the informed consent process. After study completion, the results will be published. Trial Registration: ClinicalTrials.gov NCT03451344, https://clinicaltrials.gov/ct2/show/NCT03451344.

Role of ERK signaling pathway in morphine-or sufentanil-induced inhibition of arrhythmia induced by myocardial ischemia-reperfusion in rats: the relationship with Cx43 expression / 中华麻醉学杂志

Objective To evaluate the role of extracellular signal-regulated kinase (ERK) signaling pathway in morphine-or sufentanil-induced inhibition of arrhythmia induced by myocardial ischemia-reperfusion (I/R) in rats and the relationship with connexin43 (Cx43).Methods Forty-eight healthy SPF adult male Sprague-Dawley rats,weighing 200-300 g,were randomly divided into 6 groups (n=8 each) using a random number table:sham operation group (group S);I/R group;morphine group (group M);sufentanil group (group Suf);morphine + ERK inhibitor PD98059 group (group MP);sufentanil + PD98059 group (group SP).Myocardial ischemia was induced by 30 min occlusion of the left anterior descending branch of the coronary artery,followed by reperfusion.In M and Suf groups,the animals were subjected to three cycles of 5-minute drug infusion (morphine 0.3 mg/kg and sufentanil 3 μg/kg,respectively) via the femoral vein interspersed with 5-minute drug-free periods starting from the time point immediately before ischemia.PD98059 10 mg/kg was injected intravenously at 10 min before ischemia in MP and SP groups.The development of ventricular arrhythmia was recorded within 30 min of ischemia and 30 min of reperfusion,and the arrhythmia was scored (AS).The animals were then sacrificed at 120 min of reperfusion,and the myocardial specimens were obtained for determination of the expression of total Cx43 (t-Cx43),phosphorylated Cx43 (p-Cx43),and phosphorylated ERK (p-ERK) by Western blot.Results Compared with group S,the AS was significantly increased,and the expression of p-Cx43 was significantly down-regulated in the other groups,and the expression of t-Cx43 and p-ERK was significantly down-regulated in I/R,SP and MP groups (P＜0.05).Compared with group I/R,the AS was significantly decreased,and the expression of t-Cx43,p-Cx43 and p-ERK was significantly up-regulated in M and Suf groups (P ＜ 0.05).Compared with M and Suf groups,the AS was significantly increased,and the expression of t-Cx43 and p-Cx43 was significantly down-regulated in SP and MP groups (P ＜ 0.05).Conclusion The mechanism by which morphine or sufentanil inhibits arrhythmia induced by myocardial I/R is associated with up-regulated expression of myocardial Cx43 after activation of ERK signaling pathway in rats.

Gender differences in recovery consequences among heroin dependent patients after compulsory treatment programs.

Studies on recovery patterns and how baseline factors influence recovery consequences among heroin dependent patients have shown mixed results. This study is aimed at describing the gender differences in long-term recovery patterns and exploring the predictors of negative recovery consequences by gender among heroin dependent patients in Shanghai, China. At baseline, this study recruited 503 heroin dependent patients discharged from Shanghai compulsory rehabilitation facilities in 2007 and 2008. In this cohort study, the baseline data was then linked with participants' 5-year follow-up data from official records. Generalized Estimating Equations (GEE) were used to compare males with females in terms of the presence of negative consequences (incarceration, or readmission to compulsory treatment, or both), in the subsequent 5-years after their discharge from compulsory treatment. Ordinary least squares (OLS) regression was used to explore factors associated to the time length of negative consequences in 5 years after the discharge for males and females separately. Our findings indicate that female heroin dependent patients tend to have less negative recovery outcomes than male patients. Male patients with a life-time history of poly drug use and female patients with borderline personality disorder are especially at risk of incarceration and readmission into compulsory treatment programs.

P300 event-related potential in abstinent methamphetamine-dependent patients.

BACKGROUND: Substance use and abuse are characterized by biases in the attentional processing of substance-related stimuli. There are no event related potential (ERP)-based studies of attentional bias for substance-related cues among methamphetamine (MA) dependent patients. The study aimed to measure changes in P300 event-related potentials elicited by MA-related words in MA-dependent individuals at baseline and after 3 and 6 months of abstinence, examining the relationship of ERP changes to craving. METHOD: 26 MA-dependent patients (14 male) newly enrolled in two compulsory treatment centers in China and 29 healthy controls (15 male) were included in this study. At baseline (2-3 weeks in treatment) and after 3 and 6 months of abstinence from MA use, we obtained ERP data during a Stroop color-matching task using MA-related and neutral words. Self-reported craving was measured by a Visual Analog Scale (VAS). FINDINGS: Increased P300 amplitudes elicited by MA-related words were observed over left-anterior electrode sites. Abnormal P300 amplitudes declined to the normal levels of healthy controls at the end of 3 months of abstinence, and the decrease was maintained up to the end of 6 months of abstinence. The behavioral data did not show similar changes. The positive relationship between the changes of VAS scores for MA craving and the changes of P300 amplitudes over left anterior electrode sites elicited by MA-related words within the first 3 months was significant. CONCLUSION: These findings highlight the potential use of ERP as an objective index to track changes in subjective MA craving among abstinent MA-dependent patients.
