Objective To understand the correct sexual health knowledge and source of sexual information among college students in Kunming, and provide the practical suggestions for students' sexual education. Methods A self-administered questionnaire survey was conducted among 950 students chosen from 5 universities in Kunming by cluster multistage sampling. Results The college students' health knowledge accuracy has certain significant differences between men and women, living urban and rural, inside and outside the province, and the Han and other nationalities. The most conversation partner discussing sex for the first time is their companion. Students get sex knowledge most in junior high school, and the school is the most important way to get these knowledge. Conclusion Sexual health knowledge education should be balanced between boys and girls, rural area students and minority students' knowledge of sexual health should be strengthened, and make them have a correct understanding onsex. In addition, strengthen the familysex knowledgeis also important.

The results were determined by ELISA method. Results: Besides colchicine, the others amygdalin and cordyceps. Cordyceps, the water soluble extract of Radix Salviae Miltiorrhizae) showed the obvious raising actions on albumin synthesis and secretion of fibrous hepatic cells of rat ( P

We aimed to study the association between sperm DNA fragmentation and recurrent pregnancy loss (RPL) in the Chinese population via a retrospective observational study of Chinese couples who had experienced RPL between May 2013 and August 2018. The study population included 461 men from couples with RPL and 411 men from a control group (couples with clinical pregnancy via in vitro fertilization owing to female causes). Routine semen analysis, sperm chromatin analysis, and microscopic (high-power) morphological analysis were performed using semen samples. Semen samples were assessed for volume, sperm count, and motility. The sperm DNA fragmentation index (DFI) was calculated, and the median DFI was obtained. Men were categorized as having normal (37.8%; DFI ≤ 15.0%), moderate (33.6%; 15.0% < DFI < 30.0%), or severe (28.6%; DFI ≥ 30.0%) DNA fragmentation levels. The percentage of men with severe DNA fragmentation was significantly higher in the RPL (42.3%) group than that in the control group (13.1%), whereas the percentage of men with normal levels of DNA fragmentation was significantly lower in the RPL group (22.8%) than that in the control group (54.7%). Subsequent analysis also demonstrated that the sperm DNA fragmentation rate had a moderate reverse correlation with the sperm progressive motility rate (r = -0.47, P < 0.001) and the total motile sperm count (r = -0.31, P < 0.001). We found a positive correlation between RPL and sperm DNA fragmentation. The results suggest that increased sperm DNA damage is associated with RPL.

Optical coherence tomography (OCT) has been developing continuously since its first application in clinical practice in the 1990's. Optical coherence tomography angiography (OCTA) is becoming progressively popular, as it can provide real-time blood flow parameter by detecting active red blood cells in capillaries without using a contrast agent. OCTA plays an important role in diagnosing eye diseases, such as diabetic retinopathy, retinal vessel occlusion, inflammatory eye disease, thyroid-associated ophthalmopathy, etc. This article reviewed the use of OCTA in auxiliary diagnosis of eye diseases.

Objective: To explore the difference between hybrid coronary revascularization (HCR) and off-pump coronary artery bypass grafting (OPCABG) on two-vessel coronary artery disease with proximal left anterior descending stenosis with propensity score matching. Methods: The patients with two-vessel coronary artery disease with proximal left anterior descending stenosis who underwent isolated HCR or OPCABG were selected in Ruijin Hospital from January 2009 to December 2016. The propensity score methodology was used to obtain risk-adjusted outcome. Kaplan-Meier analysis was applied to estimation of major adverse cardiac and cerebrovascular events (MACCE)-free survival rate and target vessel revascularization (TVR)-free survival rate. Results: The average follow-up time was 59 months (13-104 months). The length of hospital stay of HCR group was significantly shorter than that of OPCABG group [(15.3±4.5) d vs (17.6±5.4) d, P=0.027]. There was no statistical difference in other short-term clinical endpoints in hospital. In midterm, there was no statistical difference in the rate of MACCE (11.4% vs 13.3%, P=0.968), death (2.3% vs 4.4%, P=0.984), myocardial infarction (2.3% vs 2.2%, P=0.485), stroke (4.5% vs 6.7%, P=0.979) and TVR (4.5% vs 2.2%, P=0.984) between two groups. And there was no statistical difference in MACCE-free survival rate (P=0.906) and TVR-free survival rate (P=0.541) between two groups. Conclusion: HCR provides favorable midterm outcomes for selected patients with two-vessel coronary artery disease with proximal left anterior descending stenosis. It might provide a promising alternative to OPCABG.

OBJECTIVETo observe the effect of Changji' an (CJA) oral liquid on the activated signal alterative intensity (ASAI) in intracranial algesthesia domain in patients with diarrhea type irritable bowel syndrome (IBS) due to Gan-Pi disharmony.

METHODSTwenty-four patients were randomly divided into 2 groups, 14 in the treated group and 10 in the control group, they were administrated with CJA and placebo respectively. The sensory threshold and score in the two groups recorded by rectal inflation test were compared and analyzed. The change of ASAI in intracranial algesthesia domain was analyzed by functional magnetic resonance imagine (fM-RI) during rectum being inflated with 30 ml, 60 ml, 90 ml and 120 ml of gas respectively.

RESULTSThe initial sensory thresholds in the two groups were insignificantly different, but significant difference did show between the two groups in urgent defecation threshold and pain threshold after treatment (P < 0.05). Comparison in visual simulative scores between the two groups after treatment at rectal inflated for 30 ml showed no significant difference, but it showed significant difference when the inflation was over 30 ml (P < 0.05). In the treated group, the ASAI in insula cortex when rectal inflation being 90 ml or 120 ml and that in thalamus when rectal inflation being 120 ml were significantly decreased (P < 0.05). But in the control group, it changed insignificantly after treatment.

CONCLUSIONThe treatment of CJA on Gan-Pi disharmony caused diarrhea type IBS might be effected by regulating the ASAI in intracranial insula cortex and thalamus.

Multiple system atrophy is a neurodegenerative disease, which is characterized by a combination of autonomic failure, Parkinsonian features, pyramidal and cerebellar dysfunction, and is poorly reactive to levodopa. Few biomarkers with high sensitivity or specificity have been applicable in the diagnosis of multiple system atrophy, making it a challenge to correctly diagnose this disease. Therefore, some researches combined several biomarkers to improve the diagnosis accuracy. Apart from those in body fluid, progress has been made in new biomarkers of neuroimaging and pathology. In this review, the advances in the identification of biomarkers of multiple system atrophy are summarized, and some candidate biomarkers that worth more investigation, including proteins and miRNAs in blood or cerebrospinal fluid, parameters in molecular and functional imaging, and pathologic features of peripheral tissue are described.

Objective: To analyze the feasibility, safety and preliminary clinical results of quantitative flow ratio (QFR)-guided surgical coronary revascularization. Methods: From Jan 2018 to June 2019 at the Department of Cardiovascular Surgery, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, patients undergoing elective cardiac surgery with any coronary stenosis ≥ 50%, evaluated by preoperative coronary angiography visualization, were enrolled consecutively. There were 82 patients with 174 coronary artery vessels. Coronary artery bypass grafting (CABG) was recommended with a QFR value ≤ 0.8. The data of baseline characteristics, surgical procedure and perioperative outcomes were collected and analyzed. Results: QFR analysis was successfully carried out in 82 patients and 174 coronary artery vessels. QFR was detected positive ( ≤ 0.8) in 53 vessels (30.5%) and negative (>0.8) in the remaining 121 vessels (69.5%). As guided with QFR, 39 patients (47.6%) with 62 vessels (35.6%) proceeded to surgery for primary heart disease with concomitant CABG as planned, while the remaining 43 patients (52.4%) with 112 vessels (64.4%) changed revascularization strategy or spared CABG. Fifteen patients with simple coronary artery disease avoided CABG and discharged. Among the remaining 67 patients operated on, there were 2 deaths, 4 hemodialysis for new renal failure, 1 perioperative myocardial infarction and 1 stroke within 30 d. No unplanned revascularization was observed. The composite adverse events occurred in 6 cases (9.0%). Conclusion: QFR-guided surgical coronary revascularization is feasible and safe. This strategy could reduce the unnecessary bypass grafting. Further follow-up and prospective clinical trials are warranted to evaluate the effectiveness.

OBJECTIVETo investigate best diagnosing methods and therapy for patients with biliary tract complications after liver transplantation and analyze related factors.

METHODSA review was made of data collected from 96 patients, and confirmed by retrospective case notes examination.

RESULTSA total of 94 patients (97 grafts) survived more than 2 days after transplantation; of whom, 92 had an end-to-end biliary anastomosis with a T tube. The average follow-up was 5.8 months (range: 0.3 - 10.2 months). Among the 94 patients, eight (8.5%, 8/94) had complications: leakage during T-tube removal (2 patients), leakage at an earlier stage (2), simultaneous stricture and leak (2) and just stricture (2). Six patients with biliary tract complications had predisposing factors including hepatic artery stenosis (2 patients, including one hepatic artery stenosis combined with severe rejection, hepatic artery thrombosis (3), and donor-recipient bile duct mismatch (1). There was no difference in cold ischemic time. With hepatic artery thrombosis and/or stenosis > 50%, five patients were re-transplanted; without hepatic artery thrombosis and/or stenosis < 50%, three patients required endoscopic stenting and radiological percutaneous drainage of bile collection with or without balloon dilation. All patients survived.

CONCLUSIONSBiliary strictures occur later than leaks after surgery. Without hepatic artery thrombosis and/or stricture, there is no need for surgery; with hepatic artery thrombosis and/or stricture > 50%, re-transplantation is needed as early as possible.

OBJECTIVETo explore the mechanism and efficiency of Changji'an (CJA) in treating irritable bowel syndrome through studying the relationship between serotonin transporter (SERT) and visceral hypersensitivity in rats.

METHODSMale SD rats were randomly divided into 4 groups: the normal control group, the model group, the high-dosage and low-dosage CJA (CJAH and CJAL) groups. Visceral hypersensitivity model was established by colorectal distension. Normal saline and different doses of CJA were administrated to rats respectively, starting from the 10th day of modeling for 10 days. After then, the abdominal withdrawal reflex (AWR) was scored for semi-quantitative estimation of visceral sensitivity, and tissues of brain and colon were harvested for detecting expressions of SERT and serotonin (5-HT) with Western blot, real-time PCR and immunohistochemistry.

RESULTSAs compared with the normal controls, in model rats, the AWR score and content of 5-HT in intestinal mucosa were higher (P < 0.05), protein and mRNA expressions of SERT in colon and nucleus raphes dorsalis (NRD) were lower (P < 0.05), but all these indexes were improved significantly after CJA treatment, either in the CJAH or CJAL group (all P < 0.05). Besides, the number of 5-HT energic neuron in the model group and CJA groups was lower than that in the normal control group (P < 0.05).

CONCLUSIONCJA has therapeutic effect for improving visceral hypersensitivity in irritable bowel syndrome by way of regulating colonic expression of SERT and content of 5-HT.
