ObjectiveTo explore the clinical efficacy of Huangjin Shuangshen Jiawei （HJSSJW） granules in treating postoperative anxiety and depression after percutaneous coronary intervention （PCI） for coronary heart disease and the effects of this medicine on inflammatory cytokines. MethodNinety-four patients diagnosed with anxiety and depression after PCI were randomized into observation and control groups （47 cases） by the double-blind method. On the basis of conventional Western medical treatment， the observation group was treated with HJSSJW granules for 12 weeks， and the control group with the simulant of HJSSJW granules for 12 weeks. The two groups were compared in terms of Hamilton Anxiety and Depression Scales （HAMA-14， HAMD-24）， Pittsburgh Sleep Quality Inventory （PSQI）， Seattle Angina Score （SAQ）， TCM symptom scores， traditional Chinese medicine （TCM） symptom score and response rate， serum levels of hypersensitive-C reactive protein （hs-CPR）， tumor necrosis factor （TNF）-α， and interleukin （IL-6）， and incidence of major adverse cardiovascular events （MACEs） and adverse reactions. ResultAfter treatment， both groups showed declined scores of HAMA-14， HAMD-24， and PSQI （P<0.05， P<0.01） and the observation group had lower scores of HAMA-14， HAMD-24， and PSQI than the control group （P<0.01）. The scores of SAQ in both groups increased after treatment （P<0.01）， and the observation group had higher score of each dimension than the control group （P<0.05）. The TCM symptom scores decreased in both groups after treatment （P<0.01）， and they were lower in the observation group than in the control group （P<0.05）. The total response rate regarding TCM symptoms in the observation group was higher than that in the control group （χ²=9.225， P<0.01）. After treatment， the levels of hs-CPR， IL-6， and TNF-α became lowered in both groups （P<0.01）， and the observation group had lower levels of hs-CPR， IL-6， and TNF-α than the control group （P<0.05）. The incidence of MACEs in the observation group was lower than that in the control group during the 90 d of the follow-up period （χ²=4.242， P<0.05）. No adverse reactions associated with the use of HJSSJW granules were observed during the trial period. ConclusionHJSSJW granules can alleviate the bad mood， improve sleep， mitigate somatic symptoms， improve the quality of life， reduce inflammatory damage， and improve prognosis， being safe for clinical use in patients with postoperative anxiety and depression after PCI for coronary heart disease.

Objective:To investigate the effect of microwave on human adenovirus type 2 (HAdV-2) capsid protein in simulated infectious wastes.Methods:Droplets of HAdV-2 virus suspension were added to medical disposable gloves to simulate infectious waste, irradiated under different microwave conditions, the temperature change was recorded, and the irradiated viral supernatant was treated with Dnase I and detected by PCR and qPCR to determine the effect of microwave on the integrity of the viral capsid. ELISA was used to detect the effect of microwave irradiation on the structure of viral hexon protein. The virus was treated alone at the highest temperature during microwave irradiation to investigate whether there were non-thermal effects during microwave disinfection.Results:The maximum temperature during microwave irradiation was 76 ℃, and the PCR and qPCR result showed that Dnase I could significantly damage the viral nucleic acid after microwave irradiation, while the virus control group and heat treatment group were not significantly affected, indicating that microwave irradiation could destroy the integrity of the viral capsid. The result of ELISA showed that microwave irradiation could significantly weaken the binding ability of Hexon protein and antibody, and the result of heat treatment group were similar.Conclusions:Microwave irradiation can destroy the integrity of the HAdV-2 capsid and the structure of Hexon protein, in which the damage to the integrity of the capsid is mainly due to non-thermal effects, and the structural changes of hexon protein are mainly due to thermal effects.

Objective:To offset the shortage of traditional large-scale population surveillance and provide early-warning signals in the early stage of the outbreak of COVID-19, people in Chongqing had carried out severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monitoring since 2023.Methods:After COVID-19 was managed with measures against Class B infectious diseases, we selected five sewage treatment plants with automatic sample collection facilities in four districts of the main city. Two samples of sewage from each sewage treatment plant were collected every week. Then SARS-CoV-2 from these samples was concentrated by aluminum hydroxide adsorption-precipitation, detected and analyzed by multiple real-time fluorescent RT-PCR.Results:From January 16 to December 31 of 2023, a total of 496 sewage samples were monitored, of which 285 samples were positive by SARS-CoV-2 nucleic acid assay, with a total detection rate of 57.46%. The detection rate of SARS-CoV-2 in weeks 3-5, 18-21 and 40-47 was 100.00%. The daily mean nucleic acid concentration of SARS-CoV-2 in sewage peaked in the 18th week, and then began to decline, entering a low level and fluctuated in epidemic period. The variable trend of daily mean concentration of SARS-CoV-2 nucleic acid was basically consistent with daily number of SARS-CoV-2 infected patients or SARS-CoV-2 positive rate in fever clinic counted by infectious disease monitoring system.Conclusions:The detection rate of SARS-CoV-2 in sewage of Chongqing is relatively high, especially in April to May, and sewage monitoring can indirectly reflect the status of COVID-19 infection.

Objective:To study the inactivation effects of microwave on human adenovirus 2 (HAdV-2) in simulated infectied wastes, and to explore its molecular mechanism.Methods:25 μl of HAdV-2 virus suspension was dripped with medical disposable gloves, masks and cotton swabs to simulate infectied wastes, and irradiated under different microwave conditions: gloves and masks were irradiated for 30 s, 60 s, and 90 s at 300 W, 500 W, and 700 W, respectively. Cotton swabs irradiate 60 s, 90 s, 120 s at 500 W and 700 W respectively. Temperature changes were recorded, and the inactivation logarithmic values were calculated by the 50% endpoint method to evaluate the microwave inactivation effects, and the proliferation ability of the virus was detected by qPCR. The damage of Penton, Fiber, Hexon and E2 B genes was detected by PCR. The virus was treated with the highest temperature of 76 ℃ during microwave irradiation to study whether there was non-thermal effect during microwave disinfection. Results:After microwave irradiation of infectied waste, the temperature of masks and gloves carriers rises rapidly, with the highest temperature of 76 ℃. The temperature of the cotton swab carriers rose slowly, and the highest temperature is 65 ℃. The inactivation effect of microwave on HAdV-2 was positively correlated with microwave power and irradiation time. In the mask and glove group, microwave power of 700 W irradiated for 60 seconds, and the inactivation logarithm value could reach 3.0, In the cotton swab group, microwave power of 700 W irradiated for 120 seconds, and the inactivation logarithm value was still less than 3.0. This indicated that there were differences in the conditions for microwave inactivation of the virus in different carriers. The qPCR result showed that microwave irradiation could weak the proliferation ability of the virus. Microwave irradiation had no effect on the virus's Penton and Fiber genes, but caused some damage to the Hexon and E2 B genes. The inactivation effect of individual heat treatment on HAdV-2 was weaker than that of microwave irradiation, and there was no damage to the Hexon, Penton, Fiber, and E2 B genes. This indicated the presence of non thermal effects during the microwave inactivation process. Conclusions:Microwave irradiation can inactivate HAdV-2 in simulated infectied wastes through thermal and non-thermal effects, and its damage to viral DNA is one of the mechanisms of virus inactivation.
