Objective To investigate the factors influencing prognosis in patients with acute myocardial infarction complicated with cardiogenic shock undergoing primary percutaneous coronary intervention(PPCI).Methods Patients with acute myocardial infarction complicated with cardiogenic shock who underwent PPCI at our hospital between January 2015 and December 2019 were enrolled.Clinical baseline characteristics,coronary angiography and PCI-related parameters,and mechanical support information were collected.The patients were followed up for one year and divided into survival and death groups based on their survival status within one year.Differences in various factors between the two groups were compared.Results A total of 40 patients were enrolled,including 26 in the survival group and 14 in the death group.There were no differences in baseline data,diagnosis,risk factors,and comorbidities between the two groups.The survival group had a lower heart rate and higher blood pressure trend at admission compared to the death group.Myocardial enzymes were significantly lower in the survival group compared to the death group(median CK peak:496.00(198.25,2 830.00)U/L vs.3 040.00(405.75,5 626.53)U/L,P=0.003;median CK-MB peak:52.65(31.75,219.50)U/L vs.306.00(27.25,489.63)U/L,P=0.006).When comparing coronary angiography and PCI-related indicators between the two groups,the survival group had a higher rate of complete revascularization compared to the control group(53.85％vs.21.43％,P=0.048).The survival group had a higher proportion of extracorporeal membrane oxygenation(ECMO)combined with intra-aortic balloon pump(IABP)support compared to the control group[38.46％vs.7.14％,P=0.034].Conclusions Survival in patients with acute myocardial infarction complicated with cardiogenic shock undergoing PPCI is associated with lower level of myocardial enzymes,ECMO combined with IABP support and complete revascularization.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

OBJECTIVE: To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris. METHODS: A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment. RESULTS: There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P<0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P<0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P<0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P<0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P<0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P<0.05). No obvious adverse reaction was found in either group. CONCLUSION ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction.

OBJECTIVETo translate the English version of The Premature Ejaculation Diagnostic Tool (PEDT) into Chinese, evaluate its reliability and validity, and analyze its feasibility in the diagnosis of premature ejaculation (PE).

METHODSFollowing the forward-backward translation procedure, we developed the Chinese version of PEDT, which was then revised by andrologists and bilingual linguists. We enrolled subjects with or without PE from 15 urological or andrological clinics in China and obtained the information about their demographic characteristics, PEDT scores, and intra-vaginal ejaculation latency time (IELT). We evaluated the internal consistency of PEDT using Cronbach alpha, was examined its reliability and stability by test-retest analysis, analyzed its correlation with IELT by Spearman correlation analysis, and tested its sensitivity and specificity by receiver operating characteristic ( ROC) analysis.

RESULTSTotally, 570 PE patients (aged [30.66 ± 7.11] years) and 226 non-PE men (aged [33.01 ± 5.41] years) were recruited, with the mean IELT of (1.34 ± 0.54) min in the former and (11.09 ± 7.5) min in the latter group. The Cronbach's alpha of the Chinese version of PEDT was 0.79, and the test-retest correlation coefficient was 0.75 (P < 0.01). The PEDT score was negatively correlated with IELT (Spearman's p = -0.52, P < 0.01). When the cutoff value of PE diagnosis was defined as 7.5, the sensitivity and specificity of PEDT were 0.80 and 0.78, and when as 8.5, they were 0.72 and 0.89, respectively.

CONCLUSIONThe Chinese version of PEDT was demonstrated to have good internal consistency, reliability, and validity, as well as a high predictability for PE. It can be used as a reliable and convenient tool to screen PE among Chinese men.

OBJECTIVETo investigate the application of the Chinese Urological Association (CUA) Guidelines on Prostatitis and its effects on the clinical practice patterns of diagnosing and treating chronic pelvic pain syndrome (CPPS) among Chinese urologists and andrologists.

METHODSWe conducted a questionnaire investigation on the application of the CUA Guidelines on Prostatitis among the urologists and andrologists of 173 hospitals in 21 cities of China, and performed statistical analyses on all the eligible questionnaires collected.

RESULTSOf the 1 056 questionnaires distributed, 851 (80.6%) were eligible, of which 71.6% were from the urologists or andrologists in grade 3 hospitals, 80.7% of them with senior or intermediate professional titles and 97.5% had studied the CUA Guidelines. Most of the subjects agreed that Type III prostatitis is a clinical syndrome, whose diagnosis should exclude other conditions with similar symptoms, and whose treatment should aim at relieving pain, alleviating urination symptoms and improving the quality of life. Those who had and those who had not studied the CUA Guidelines differed in their viewpoints on CPPS as illustrated in the book. In clinical practice, the most common treatment options for CPPS were psychological therapy (80.7%), medication (80.4%) and life style adjustment (79.6%), and the most frequently used drugs were phytotherapy (80.0%), alpha-blockers (68.9%) and antibiotics (61.0%).

CONCLUSIONCUA Guidelines on Prostatitis has gained a nationwide application and promoted the standardization of the management of CPPS in China.

OBJECTIVETo observe the efficacy of Qilin Pills in the treatment of oligoasthenospermia.

METHODSWe conducted a multi-centered open controlled clinical trial by including 220 oligoasthenospermia patients in a trial group and another 110 as controls. The patients in the trial group were treated with Qilin Pills at the dose of 6 g tid, and the controls given Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks. Then we evaluated the clinical effects of Qilin Pills with sperm concentration, the numbers of grade a and grade a + b sperm, and sperm motility as the primary, and the pregnancy rate of the patients'spouses as the secondary therapeutic indexes.

RESULTSA total of 310 patients accomplished the clinical trial, 208 in the trial and 102 in the control group. Compared with the baseline, significant improvement was observed in the semen parameters after 4, 8 and 12 weeks of treatment in both the trial and control groups except sperm density and the number of grade a sperm in the control after 4 weeks (P < 0.01), and the improvement was even more significant in all the semen parameters at the same time points in the trial than in the control group (P < 0.01).

CONCLUSIONQilin Pills can evidently improve the seminal quality of oligoasthenospermia patients with no obvious adverse events.
