BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Background::A phase II trial on recombinant human tenecteplase tissue-type plasminogen activator (rhTNK-tPA) has previously shown its preliminary efficacy in ST elevation myocardial infarction (STEMI) patients. This study was designed as a pivotal postmarketing trial to compare its efficacy and safety with rrecombinant human tissue-type plasminogen activator alteplase (rt-PA) in Chinese patients with STEMI.Methods::In this multicenter, randomized, open-label, non-inferiority trial, patients with acute STEMI were randomly assigned (1:1) to receive an intravenous bolus of 16 mg rhTNK-tPA or an intravenous bolus of 8 mg rt-PA followed by an infusion of 42 mg in 90 min. The primary endpoint was recanalization defined by thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3. The secondary endpoint was clinically justified recanalization. Other endpoints included 30-day major adverse cardiovascular and cerebrovascular events (MACCEs) and safety endpoints.Results::From July 2016 to September 2019, 767 eligible patients were randomly assigned to receive rhTNK-tPA ( n = 384) or rt-PA ( n = 383). Among them, 369 patients had coronary angiography data on TIMI flow, and 711 patients had data on clinically justified recanalization. Both used a –15% difference as the non-inferiority efficacy margin. In comparison to rt-PA, both the proportion of patients with TIMI grade 2 or 3 flow (78.3% [148/189] vs. 81.7% [147/180]; differences: –3.4%; 95% confidence interval [CI]: –11.5%, 4.8%) and clinically justified recanalization (85.4% [305/357] vs. 85.9% [304/354]; difference: –0.5%; 95% CI: –5.6%, 4.7%) in the rhTNK-tPA group were non-inferior. The occurrence of 30-day MACCEs (10.2% [39/384] vs. 11.0% [42/383]; hazard ratio: 0.96; 95% CI: 0.61, 1.50) did not differ significantly between groups. No safety outcomes significantly differed between groups. Conclusion::rhTNK-tPA was non-inferior to rt-PA in the effect of improving recanalization of the infarct-related artery, a validated surrogate of clinical outcomes, among Chinese patients with acute STEMI.Trial registration::www.ClinicalTrials.gov (No. NCT02835534).

Objective:To understand the source and related factors among heterosexual casual partners among male college students for providing AIDS prevention strategies in this population.Methods:Stratified cluster sampling method was used to conduct a questionnaire survey among 31 674 college students in 13 colleges in Zhejiang Province, from October to November, 2018. A total of 2 665 male college students who reported having had heterosexual casual behavior and the source of their sexual partners were recruited. Data on demographic characteristics, knowledge of HIV/AIDS prevention, sexual behavior, and having received AIDS-related interventions were collected. The multivariable logistics regression model was used to analyze the related factors of the source of casual heterosexual behavior partners among male college students.Results:A total of 423 male college students having casual heterosexual sex were investigated, accounting for 15.9% (423/2 665) of the male college students who self-reported having sexual behaviors and informed their sexual partners. Among them, 39.4% (147/373), 37.5% (140/373), and 23.1% (86/373) of participants had 1, 2-4, and 5 or more heterosexual casual sexual partners, respectively. 40.1% (167/416) of participants used condoms consistently with casual partners. 143 (33.8%) participants with social individual's partners were an average age of (20.27±1.40) years old. Multivariate logistic regression analysis showed that: when compared with one person, common acquaintances, and no heterosexual casual partners in the previous year, the factors that related to the source of heterosexual casual partners of male college students appeared as follows: the number of heterosexual casual sexual partners ≥5 (a OR=3.00, 95% CI:1.53-5.89), seeking the casual sexual partners through entertainment venues (a OR=3.04,95% CI:1.64-5.64), male college students having sex with a regular partner in the last one year (a OR=0.41, 95% CI:0.25-0.68). Conclusions:Some of the male college students had heterosexual casual sexual behaviors, with the related factors as having five or more heterosexual casual sexual partners, seeking casual sex partners through entertainment venues, and low condom use. Self-protection awareness and ability should be emphasized to advocate safe sex to reduce the risk of AIDS transmission among college students.

Skin ulcers are the most prevalent consequence of diabetes mellitus, and people with diabetic ulcers have a substantially greater death risk than those who do not have ulcers. Herbal medications have gained wide concern in recent years due to their multi-component, multi-target, and multi-pathway synergistic therapeutic effects. Clinical trials have demonstrated the safety and efficacy of herbal treatments in diabetic refractory ulcers. To systematically evaluate the healing effect of herbs on diabetic wounds, a literature search was conducted, the mechanism of action of 15 herbal extracts in promoting diabetic wound healing were reviewed, and the classification based on traditional Chinese medicine theory was discussed, which could provide a reference for the precise treatment and exploitation of herbal medicines for diabetic ulcers.

【Objective】 To identify the key factors that regulate the physical vacuum stirring deoxygenation process of bovine hemoglobin and evaluate the stabilities of polyHb solution with different oxygenation degree. 【Methods】 The effects of several factors including gas liquid specific phase boundary area, pH values and polyHb concentrations on deoxygenation process were investigated through monitoring the oxygen saturation of polyHb solution. Furthermore, the MetHb contents of the studied polyHb solutions were measured at regular intervals during the experiments to evaluate the molecular stability of the polyHb through monitoring the oxidation degrees of the experimental Hb solutions under the mimic pasteurevirus inactivation conditions. 【Results】 The results showed that the more gas liquid specific phase boundary area could accelerate deoxygenation rate, the better deoxygenation results could be yielded. On the other hand, lower pH value could promote the deoxygenation process of the polyHb solution due to the decreasing of oxygen affinity of the polyhemoglobin molecules. Furthermore, results of investigation about the Hb concentration presented that Hb concentration had no remarkable effects on the deoxygenation of polyHb. In addition, the results from the stability experiments presented that higher degree of deoxygenation could decrease the oxidation process and thus increase the heat tolerance of the polyhemoglobin. 【Conclusion】 The deoxygenation of polyhemglonbin could improve the stability of the polyhemoglobin and the deoxygenation process could be regulated by changing the gas liquid specific phase boundary area and oxygen affinity. This study could provide reference and preliminary basis for the industrialization and development of HBOCs in the future.

Objective:To study the effect of duodenal papillary morphology on selective biliary cannulation (SBC).Methods:Data of 912 patients with biliopancreatic diseases treated with endoscopic retrograde cholangiopancreatography (ERCP) at the Department of Gastroenterology, Affiliated Hospital of Northwest Minzu University from January 2018 to January 2020 were retrospectively analyzed. Duodenal papillary morphology of patients was classified into 4 types by using Haraldsson's endoscopic classification. The success rate of SBC, the pre-incision rate, the difficult intubation rate and the incidence of post-ERCP pancreatitis (PEP) of different papillary types were analyzed.Results:A total of 912 patients were enrolled in this study, and 86.95% (793/912) duodenal papilla conformed to one type of the classification, of which 77.18% (612/793) were regular type (type Ⅰ), 10.21% (81/793) small nipple type (type Ⅱ), 8.58% (68/793) protruding or drooping type (type Ⅲ), and 4.04% (32/793) wrinkled or ridged type (type Ⅳ). The success rates of SBC in four types of duodenal papilla were 98.86% (605/612), 90.12% (73/81), 88.24% (60/68) and 96.60% (28/32) respectively. The success rate of SBC of type Ⅰ was higher than those of type Ⅱ-Ⅳ (all P<0.008) and there was no significant difference between those of type Ⅱ and type Ⅲ ( P> 0.008). The pre-incision rate in the four types of duodenal papilla were 7.84% (48/612), 32.10% (26/81), 50.00% (34/68) and 25.00% (8/32) respectively. The pre-incision rate of type Ⅰ was lower than those of type Ⅱ-Ⅳ (all P<0.008), and there was no significant difference between those of type Ⅱ and type Ⅲ ( P>0.008). The difficult intubation rate in the four types of duodenal papilla were 12.42% (76/612), 39.51% (32/81), 58.82% (40/68) and 28.12% (9/32) respectively .The difficult intubation rate of type Ⅰ was lower than those of type Ⅱ and type Ⅲ (both P<0.001), and that of type Ⅲ was higher than that of type Ⅳ ( P=0.004) . There was no significant difference between those of type Ⅰ and type Ⅳ or type Ⅱ and type Ⅲ (both P>0.008). The incidences of PEP of the four types were 2.61% (16/612), 12.35% (10/81), 5.88% (4/68) and 6.25% (2/32) respectively. The incidences of PEP of type Ⅱ was higher than that of type Ⅰ ( P<0.001) , and there was no significant difference between those of type Ⅰ and type Ⅳ or type Ⅱ and type Ⅲ (both P>0.008). Conclusion:SBC is affected by duodenal papilla morphology, easiest for type Ⅰ and hard for type Ⅱ and Ⅲ. Attention should be paid to risk of PEP in SBC of type Ⅱ.
