Objective To observe the clinical efficacy ofTong Yuan(short forTong Du Tiao Shen,Yin Qi Gui Yuan, referring to unblocking the Governor Vessel, regulating mind, and guiding qi back to the origin) needling method plus Letrozol and human chorionic gonadotropin (HCG) in treating refractory sterility caused by polycystic ovary syndrome (PCOS).Method Sixty clomiphene citrate-resistant PCOS-induced sterility patients were recruited and randomized into two groups. The treatment group was intervened byTong Yuanneedling plus Letrozol and HCG, while the control group was intervened only by Letrozol and HCG, both for 3 months. Prior to and after the treatment,the levels of estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) were detected; the endometrium, ovulation and pregnancy rates were also observed.Result After 3 menstrual cycles, the level of FSH increasedsignificantly (P<0.05), LH decreased significantly (P<0.05), LH/FSH declined significantly (P<0.05), and the level of T also dropped significantly (P<0.05) in both treatment group and control group; the level of E2also dropped significantly after the treatment in both groups (P<0.05), and the decrease in the treatment group was more significantly than that in the control group (P<0.05). The ovulation and pregnancy rates in the treatment group were significantly higher than those in the control group (P<0.05).Conclusion Tong Yuanneedling plus Letrozol and HCG can significantly down-regulate the levels of LH, E2and T, up-regulate the level of FSH, effectively improve the internal reproductive environment of refractory PCOS patients, and enhance the ovulation and pregnancy rates.

Objective To investigate the effect of liver cirrhosis on the potency of propofol for sedation in rats. Methods Fifty-eight male SD rats, aged 10-12 weeks, weighing 180-220 g, were randomly divided into 3 groups: control group (group C, n = 18), mild liver cirrhosis group (group M1, n =20) and severe liver cirrhosis group (group M2, n = 20). The model of liver cirrhosis was established using four factors described by Chen et al. After successful establishment of the model, propofol was injected intravenously. The dose of propofol was determined by up-and-down sequential method for loss of righting reflex. The dose of propofol was 5.912 mg/kg in the first rat and the ratio of the doses between the two consecutive rats was 0.85. ED50 of propofol was calculated using up-and-down sequential method. Results ED50 of propofol was significantly lower in group M1 and M2 than in group C and in group M2 than in group M1 ( P ＜ 0.05 or 0.01 ). Conclusion The liver cirrhosis can enhance the potency of propofol for sedation in rats.

Objective To study tirofiban intravenous injection,coronary artery injection of the two different methods in acute ST segment elevation myocardial infarction,the application of emergency PCI.Methods Patients underwent emergency PCI with acute ST segment elevation myocardial infarction as the research subjects,a total of 108 cases,the patients were randomly divided into the observation group and control group,54 patients in each group. In the observation group,the first dose of tirofiban was injected into the coronary artery.The control group was treated by intravenous injection.The results of the two groups were compared.Results Before treatment,TIMI level 2 and level 3 ratio,initial corrected TIMI frame count of the observation group were significantly lower than the control group (χ2 /t =4.32,4.59,5.25,all P <0.05).After treatment,MBG level 2 or level 3 ratio,post -operative corrected TIMI frame count of the observation group were significantly higher than the control group (χ2 /t =4.11,4.85,5.87, all P <0.05).1 h after PCI treatment,the number of cases of ST fully back,the added value of EF,plague index scores of observation group were 53 cases,(8.02 ±6.94)%,(0.41 ±0.28)respectively,which were significantly higher than those of the control group 36 cases,(5.87 ±6.54)%,(0.28 ±0.27)(χ2 /t =5.32,4.32,3.65,all P <0.05).Adverse events of the two groups had no significant difference (χ2 =0.52,P >0.05).Conclusion Compared with intravenous injection,tirofiban in the treatment of acute ST segment elevation myocardial infarction by intracoronary injection can improve the level of myocardial perfusion after PCI operation,promote the recovery of left ventricular function,and has high security.

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.

Objective To investigate mental health literacy (MHL) of community medical staffs in district and town of Zhongshan city,and to provide data to improve MHL of community medical staffs.Methods Totally 352 medical staffs who were not psychiatric physician and 81 psychiatric physician were selected.The Chinese Mental Health Knowledge Awareness Questionnaire (published by Ministry of Health) was used to investigate the awareness rate of mental health knowledge.Five vignettes of two schizophrenia,one bipolar disorder,one depression and one obsessive compulsive disorder,each with 8 related questions,were used to investigate the recognition and response ability.Results The average awareness rate of the two groups was more than 80.0% (87.6%,91.6%).For the item 2(75.6%,88.6%),6(74.1%,62.6%),19(36.5%,65.6%),and 20(74.1%,86.2%),the awareness rates were lower than 80.0%,and there were significant differences between the two groups (x2=8.45,4.92,27.48,6.99,all P<0.05).In vignettes survey,the correct rate was lower in the staffs who did not engaged in the mental health work than those in the other group,the difference was statistically significant(64.6% vs.75.9%,P<0.001).For both of the two groups the correct rate of depression was the lowest(x2=44.46,P<0.001).There was statistically significant difference between the total (x2=141.17,P<0.001).Conclusion The awareness rate of mental health knowledge has reached the national standards for community medical staffs,but they have to improve for some knowledge point.Their recognition and response ability for mental illness should be improved.

Objective To study the effect of acupuncture combined with clean intermittent catheterization in the treat-ment of neurogenic bladder. Methods A total of 46 patients were randomly divided into test and control groups. There were 23 patients in the each group. The clean intermittent catheterization only used in the control group. However inte-grated acupuncture and clean intermittent catheterization were used in the test group. Final the residual urine volume and the incidence of bacteriuria were researched after 5 months. Results There were 17 cases restored the micturating function in the test group, however only 7 cases in the control group. There were 3 cases suffered bacteriuria in the test group, but there were 11 cases suffered bacteriuria in the control group. The difference between the two groups was sta-tistical ly significantly (P<0.05). Conclusion Combined acupuncture with clean intermittent catheterization can effi-ciently maintain the normal function of bladder, decrease the residual urine volume, and reduce the incidence of bac-teriuria.

OBJECTIVETo observe the clinical efficacy and action mechanism of acupuncture for ovulatory disorder infertility of ovarian induction period with clomiphene citrate (CC).

METHODSThrough retrospective analysis, 36 patients with ovulatory disorder infertility were divided into CC group (16 cases) and acupuoture group (20 cases) by method. The patients in the CC group were treated with oral administration of CC (50 mg) for 5 days from the 5th day of menstruation; based on the treatment of CC, patients in the acupuncture group were treated with acupuncture; the group A of acupoint was mainly consisted of acupoints of the conception vessel and the three meridians and front- acupoints in abdomen; the group B of acupoint was mainly consisted of acupoints of the governor vessel and back- acupoints. The two groups of the acupoints were selected alternately, combined with the -guan points (Taichong (LR 3)、Hegu (LI 4)) and five- points. The needles were inserted with flying needling method, and the needles were retained for 30 min per treatment; acupuncture was given once every other day. All the patients were treated for 2 months, and treatment stopped if pregnancy occurred. The pregnancy rate, cycle ovulation rate, maximum diameter of follicle, endometrial thickness and adverse effects were compared between the two groups.

RESULTSThe pregnancy rate of the acupuncture group was 75.0% (15/20), which was superior to 37.5% (6/16) in the CC group (<0.05). The cycle ovulation rates of two groups were 70.4% (19/27, >0.05). The maximum diameter of follicle and the endometrium thickness in the acupuncture group were superior to those in the CC group (both <0.05). The incidence of adverse effects in the acupuncture group was 0% (0/20), which was lower than 18.8% (3/16) in the CC group (<0.05).

CONCLUSION acupuncture combined with CC could improve the quality of follicle and the receptivity of endometrium in patients with ovulatory disorder infertility, so as to improve the pregnancy rate, which could be used as a safe and effective means to cooperate with modern assisted reproductive technology.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Galectin⁃3 is an endogenous lectin with extensive immunomodulatory effects, and plays an important role in inflammatory response, autoimmunity and tumorigenesis. However, the expression of galectin⁃3 in ulcerative colitis (UC) and its relationship with disease activity of UC are unclear. Aims: To detect the expression of galectin⁃3 in colon tissue and serum in UC patients, and explore the relationship between galectin⁃3 and disease activity. Methods: Thirty⁃ three patients with UC diagnosed and treated from March 2019 to December 2019 at the Second Affiliated Hospital of Zhengzhou University were recruited, and 20 paracancerous normal tissue of colon cancer patients were served as controls. The expression of galectin ⁃ 3 in colon tissue was detected by immunohistochemistry SABC. Serum samples of 24 UC patients and 20 healthy controls were collected. Serum level of galectin⁃3 was detected by ELISA. Results: The positive expression rate of galectin⁃3 in colon tissue in UC patients was significantly lower than that in paracancerous normal tissue, and the difference was statistically significant (P<0.05). The positive expression rate in mild UC patients was higher than that in moderate to severe UC patients, and the difference was statistically significant (P<0.05). The positive expression rate in remission stage was higher than that in active stage, and the difference was statistically significant (P<0.05). Serum galectin⁃3 level in UC patients was higher than that in healthy control group, and the difference was statistically significant (P<0.05). Serum galectin ⁃ 3 level in moderate to severe UC patients was higher than that in mild UC group, and the difference was statistically significant (P<0.05). Serum galectin ⁃ 3 level in active UC patients was higher than that in remission UC patients, and the difference was statistically significant (P<0.05). Conclusions: In UC patients, the expression of galectin⁃3 in colon tissue and serum are dysregulated, and the expression of galectin⁃3 in colon tissue is decreased, especially in moderate to severe UC, while the serum galectin⁃3 level is opposite to the tissue expression.
