ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates （P<0.05）. Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r₀=5, α=0.3, β₁=0.08, β₂=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (r_t≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

OBJECTIVE: To explore the clinical efficacy of Wenshen Chushi Decoction combined with low intensity pulsed ultrasound (LIPUS) on erectile dysfunction (ED) caused by renal deficiency and phlegm-dampness syndrome. METHODS: One hundred and twenty ED patients were included from the Department of Andrology in the First Hospital of Hunan University of Traditional Chinese Medicine. The patients in control group were treated with Wenshen Chushi Decoction. While the patients in observation group were treated with Wenshen Chushi Decoction combined with LIPUS for 8 consecutive weeks. After the treatment, the efficacy was evaluated using the International Index of Erectile Function-5 (IIEF-5) score, Penile Flow Index (PFI), Traditional Chinese Medicine Syndrome Score, Self-Rating Depression Scale (SDS) score, and Self-Rating Anxiety Scale (SAS) score. Safety was also observed. And the efficacy was followed up 4 weeks after the end of treatment. RESULTS: Fifty-seven cases were enrolled into control group finally with 55 cases in the treatment group. After the treatment, all the patients in both of groups showed an improvement in IIEF-5 scores (P<0.01). Compared with the control group (19.09 ± 2.22), the IIEF-5 score in observation group (20.42 ± 2.39) increased significantly (P<0.01). After the treatment, the scores of PFI, TCM syndrome and SDS in both groups decreased (P<0.01, P<0.05, P<0.01). Compared with the control group (［3.77 ± 1.21］, ［9.91 ± 1.71］ and ［39.88 ± 2.63］ points), the observation group (［2.92 ± 1.08］, ［4.78 ± 1.45］, and ［34.51 ± 2.09］ points） showed a more significant decrease (P<0.01). There was no significant difference in total effective rate between the two groups (P>0.05). During follow-up, the IIEF-5 scores of both groups of patients were higher than those before (P<0.05, P<0.01), and the observation group score was higher than that in the control group (［17.15 ± 3.37］ vs ［13.63 ± 1.96］, P<0.01). No adverse reaction and abnormality of indicators occurred in both of two groups. CONCLUSION Wenshen Chushi Decoction has a significant therapeutic effect on ED caused by renal deficiency and phlegm-dampness syndrome. It can not only improve the quality of erection, but also improve the physical and mental symptoms associated with ED， which makes therapeutic effect lasting longer.

OBJECTIVE: To assess the efficacy of Qingda Granule (QDG) in ameliorating hypertension-induced cardiac damage and investigate the underlying mechanisms involved. METHODS: Twenty spontaneously hypertensive rats (SHRs) were used to develope a hypertension-induced cardiac damage model. Another 10 Wistar Kyoto (WKY) rats were used as normotension group. Rats were administrated intragastrically QDG [0.9 g/(kg•d)] or an equivalent volume of pure water for 8 weeks. Blood pressure, histopathological changes, cardiac function, levels of oxidative stress and inflammatory response markers were measured. Furthermore, to gain insights into the potential mechanisms underlying the protective effects of QDG against hypertension-induced cardiac injury, a network pharmacology study was conducted. Predicted results were validated by Western blot, radioimmunoassay immunohistochemistry and quantitative polymerase chain reaction, respectively. RESULTS: The administration of QDG resulted in a significant decrease in blood pressure levels in SHRs (P<0.01). Histological examinations, including hematoxylin-eosin staining and Masson trichrome staining revealed that QDG effectively attenuated hypertension-induced cardiac damage. Furthermore, echocardiography demonstrated that QDG improved hypertension-associated cardiac dysfunction. Enzyme-linked immunosorbent assay and colorimetric method indicated that QDG significantly reduced oxidative stress and inflammatory response levels in both myocardial tissue and serum (P<0.01). CONCLUSIONS Both network pharmacology and experimental investigations confirmed that QDG exerted its beneficial effects in decreasing hypertension-induced cardiac damage by regulating the angiotensin converting enzyme (ACE)/angiotensin II (Ang II)/Ang II receptor type 1 axis and ACE/Ang II/Ang II receptor type 2 axis.

OBJECTIVE: To evaluate the immediate effect of Kuanxiong Aerosol (KXA) on perioperative coronary microcirculation in patients with unstable angina (UA) suffering from elective percutaneous coronary intervention (PCI). METHODS: From February 2021 to July 2023, UA inpatients who underwent PCI alone in the left anterior descending (LAD) branch were included. Random numbers were generated to divide patients into the trial group and the control group at a ratio of 1:1. The index of coronary microcirculation resistance (IMR) was measured before PCI, and the trial group was given two sprays of KXA, while the control group was not given. IMR was measured again after PCI, cardiac troponin I (cTnI) and creatine kinase isoenzyme-MB (CK-MB) were detected before and 24 h after surgery, and major cardiovascular adverse events (MACEs) were recorded for 30 days. The data statistics and analysis personnel were blinded. RESULTS: Totally 859 patients were screened, and 62 of them were involved into this study. Finally, 1 patient in the trial group failed to complete the post-PCI IMR and was excluded, 30 patients were included for data analysis, while 31 patients in the control group were enrolled in data analysis. There was no significant difference in baseline data (age, gender, risk factors, previous history, biochemical index, and drug therapy, etc.) between the two groups. In addition, differences in IMR, cTnI and CK-MB were not statistically significant between the two groups before surgery. After PCI, the IMR level of the trial group was significantly lower than that of the control group (19.56 ± 14.37 vs. 27.15 ± 15.03, P=0.048). Besides, the incidence of perioperative myocardial injury (PMI) was lower in the trial group, but the difference was not statistically significant (6.67% vs. 16.13%, P=0.425). No MACEs were reported in either group. CONCLUSIONS KXA has the potential of improving coronary microvascular dysfunction. This study provides reference for the application of KXA in UA patients undergoing elective PCI. (Registration No. ChiCTR2300069831).

Objective To investigate the current situation and influencing factors of latent tuberculosis infection(LTBI)among close contacts of positive etiology pulmonary tuberculosis(PTB)patients,provide basis for formula-ting intervention measures for LTBI.Methods A multi-stage stratified cluster random sampling method was used to select close contacts of positive etiology PTB patients from 39 districts and counties in Chongqing City as the study objects.Demographic information was collected by questionnaire survey and the infection of Mycobacterium tuberculosis was detected by interferon gamma release assay(IGRA).The influencing factors of LTBI were analyzed by x2 test and binary logistic regression model.Results A total of 2 591 close contacts were included,the male to female ratio was 0.69∶1,with the mean age of(35.72±16.64)years.1 058 cases of LTBI were detected,Myco-bacterium tuberculosis latent infection rate was 40.83％.Univariate analysis showed that the infection rate was dif-ferent among peoples of different age,body mass index(BMI),occupation,education level,marital status,wheth-er they had chronic disease or major surgery history,whether they lived together with the indicator case,and whether the cumulative contact time with the indicator case ≥250 hours,difference were all statistically significant(all P＜0.05);infection rate presented increased trend with the increase of age and BMI(both P＜0.001),and decreased trend with the increase of education(P＜0.05).Logistic regression analysis showed that age 45-54 years old(OR=1.951,95％CI:1.031-3.693),age 55-64 years old(OR=2.473,95％CI:1.279-4.781),other occupations(OR=0.530,95％CI:0.292-0.964),teachers(OR=0.439,95％CI:0.242-0.794),students(OR=0.445,95％CI:0.233-0.851),junior high school education or below(OR=1.412,95％CI:1.025-1.944),BMI＜18.5 kg/m2(OR=0.762,95％CI:0.586-0.991),co-living with indicator cases(OR=1.621,95％CI1.316-1.997)and cumu-lative contact time with indicator cases ≥250 hours(OR=1.292,95％CI:1.083-1.540)were the influential fac-tors for LTBI(all P＜0.05).Conclusion The close contacts with positive etiology PTB have a high latent infection rate of Mycobacterium tuberculosis,and it is necessary to pay attention to close contacts of high age,farmers,and frequent contact with patients,and take timely targeted interventions to reduce the risk of occurrence of disease.

Objective:To investigate the clinical efficacy of continuous veno-venous hemodia-filtration (CVVHDF) combined with hemoperfusion (HP) HA380 in the treatment of heat stroke patients with multiple organ dysfunction syndrome (MODS).Methods:A retrospective and observational study was conducted. A total of 15 patients with heat stroke combined with MODS who were admitted to the department of intensive care unit (ICU)of Suizhou Central Hospital/Hubei University of Medicine from July to September 2022 were selected as the study objects. All 15 patients were treated with CVVHDF combined with HA380 based on the comprehensive management strategy for severe illness. Organ function indicators [including total bilirubin (TBil), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), creatinine (Cr), cardiac troponin T (cTnT), myoglobin (Myo), MB isoenzyme of creatine kinase (CK-MB), sequential organ failure assessment (SOFA)] and inflammatory indicators [including white blood cell count (WBC), neutrophil count (NEU), C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6)] were collected. The improvements of the above indexes at admission, after the first HP, after the second HP, after the third HP, and on the 5th day of treatment were compared. Combined with the clinical outcome of patients, the comprehensive efficacy of CVVHDF combined with HA380 in the treatment of severe heat radiation disease was evaluated.Results:There were 10 males and 5 females among the 15 patients. The average age was (64.5±11.5) years old. There were 6 cases of classical heat stroke and 9 cases of exertional heat stroke. Glasgow coma scale (GCS) was 3-8 at admission; SOFA score was 9-17 within 12 hours after admission; acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) was 25-45 within 24 hours after admission. After treatment, the IL-6 level and SOFA score gradually decreased, and there were significant differences in the decrease after the second HP compared to admission [IL-6 (ng/L): 48.37 (15.36, 113.03) vs. 221.90 (85.87, 425.90), SOFA: 8.3±3.3 vs. 11.1±2.4, both P < 0.05]. The PCT level reached its peak after the first HP [12.51 (6.07, 41.65) μg/L], and then gradually decreased, and the difference was statistically significant after the third HP [1.26 (0.82, 5.40) μg/L, P < 0.05]. Compared those at admission, Cr level significantly improved after the first HP (μmol/L: 66.94±25.57 vs. 110.80±31.13, P < 0.01), Myo significantly decreased after the second HP [μg/L: 490.90 (164.98, 768.05) vs. 3?000.00 (293.00, 3?000.00), P < 0.05], After the third HP, the CK level also showed significant improvement [U/L: 476.0 (413.0, 922.0) vs. 2?107.0 (729.0, 2?449.0), P < 0.05]. After CVVHDF combined with 3 times HP treatment, the patient's inflammatory response was gradually controlled and organ function gradually recovered. On the 5th day of the disease course, WBC, PCT and IL-6 levels were significantly improved compared to admission, and AST, CK, LDH, Cr, Myo, CK-MB, and SOFA score were significantly corrected compared with those on admission. The 24-hour survival rate of 15 patients was 86.67%, and the 24-hour, 7-day and 28-day survival rates were both as high as 73.33%. The average mechanical ventilation time of 11 surviving patients was (101.8±22.0) hours, the average continuous renal replacement therapy (CRRT) time was (58.8±11.0) hours, the average length of ICU stay was (6.3±1.0) days, and the average total hospitalization was (14.6±5.2) days. Conclusion:CVVHDF combined with HP HA380 in the treatment of heat stroke patients with MODS can effectively improve organ function and alleviate the inflammatory storm, which is an effective means to improve the rescue rate and reduce the mortality of severe heat stroke patients.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To observe the clinical efficacy of meridian massage in the treatment of lumbar disc herniation(LDH).Methods Between July 2020 and April 2023,82 patients with lumbar disc herniation were selected,including 58 males and 24 females,aged from 23 to 55 years old with an average of(43.76±6.64)years old.According to the different treatment methods,they were divided into observation group and control group with 41 cases in each group.The control group was treated with routine treatment,and the observation group was treated with meridian massage on the basis of routine treatment.In the control group,there were 30 males and 11 females;aged from 22 to 52 years old with an average of(42.27±9.34)years old;the Body mass index(BMI)ranged from 19 to 28 kg·m-2 with an average of(23.82±1.08)kg·m-2;the course of disease ranged from 0.5 to 3.0 years(2.40±0.48)years.There were 28 cases in L4,5 segment and 13 cases in L5S1 segment.In the observation group,there were 28 males and 13 females;the age ranged from 19 to 54 years old(42.19±9.26)years old;the BMI ranged from 18 to 29 kg·m-2 with an average of(23.73±1.15)kg·m-2;the course of disease ranged from 0.6 to 2.8 with an average of(2.56±0.45)years;there were 26 cases in L4,5 segment and 15 cases in L5S1 segment.Visual analogue scale(VAS),Oswestry disability index(ODI),M-JOA score and TCM syndrome score were measured before and after 3 courses of treatment,and the clinical efficacy was evaluated by the standard of curative effect evaluation.Results After treatment,VAS[(3.24±1.45)vs(4.46±0.64)],ODI[(11.45±1.98)％vs(17.21±2.74)％]and TCM symptom score[(2.03±0.27)vs(3.99±0.54)]of the observation group were lower than those of the control group.The score of M-JOA[(23.43±2.61)vs(19.37±1.62)]increased(P＜0.05).The scores of VAS,ODI andTCM symptoms in the observation group were lower than those in the control group,while the scores of M-JOA were higher than those in the control group(P＜0.05).Conclusion Meridian massage is effective in the treatment of LDH,which can effectivelyrelieve low back pain,improve clinical symptoms and increaselumbar function,which is worthy of clinical promotion.

Objective To explore the clinical efficacy and safety of early surgical treatment for spinal thoracolumbar fracture without nerve injury.Methods The clinical data of 80 patients with spinal thoracolumbar fracture without nerve injury who were admitted to the department of spinal surgery in our hospital were retrospectively analyzed.According to the different operation timing,those who underwent surgery within 72 hours after fracture were included in the early operation group(n=41),and those who underwent surgery 72 hours to 2 weeks after fracture were included in the elective operation group(n=39).All operations were performed through the Wiltse approach for short-segment pedicle screw fixation on the injured vertebra.The operation time,intraoperative blood loss,hospital stay and incidence of complication of the two groups were compared.The visual analogue scale(VAS)scores,Oswestry disability index(ODI),compression rate of the anterior edge height of the injured vertebra,and the Cobb angle in the sagittal position of the injured vertebra before surgery,1 week after surgery and 1 year after surgery were compared between the two groups.The improvement rates of the anterior edge height compression and the Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery were compared between the two groups.Results There was no significant difference in the operation time,intraoperative blood loss or total incidence of complications between the two groups(P>0.05).The hospital stay in the early operation group was shorter than that in the elective operation group,and the difference was statistically significant(P<0.05).The VAS scores and ODI 1 week and 1 year after surgery of the two groups were better than those before surgery,and the differences were statistically significant(P<0.05).There was no significant difference in the VAS scores or ODI at each time point before and after surgery between the two groups(P>0.05).The compression rate of the anterior edge height and Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the two groups were lower/smaller than those before surgery,with statistically significant differences(P<0.05).There was no statistically significant difference in the compression rate of the anterior edge height or Cobb angle before surgery in the sagittal position of the injured vertebrae between the two groups(P>0.05).The compression rate of the anterior edge height and Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the early operation group were lower/smaller than those in the elective operation group,and the differences were statistically significant(P<0.05).The improvement rates of the anterior edge height compression and the Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the early operation group were better than those in the elective operation group,and the differences were statistically significant(P<0.05).Conclusion Early surgical treatment for spinal thoracolumbar fracture without nerve damage is safe,it can significantly shorten hospitalization time,obtain good fracture reduction quality and definite therapeutic effects.However,a comprehensive preoperative evaluation of the patients' condition is necessary to ensure surgical safety.

Objective:To investigate the molecular mechanisms of chronic rhinosinusitis (CRS), to identify key cell subgroups and genes, to construct effective diagnostic models, and to screen for potential therapeutic drugs.Methods:Key cell subgroups in CRS were identified through single-cell transcriptomic sequencing data. Essential genes associated with CRS were selected and diagnostic models were constructed by hdWGCNA (high dimensional weighted gene co-expression network analysis) and various machine learning algorithms. Causal inference analysis was performed using Mendelian randomization and colocalization analysis. Potential therapeutic drugs were identified using molecular docking technology, and the results of bioinformatics analysis were validated by immunofluorescence staining. Graphpad Prism, R, Python, and Adobe Illustrator software were used for data and image processing.Results:An increased proportion of basal and suprabasal cells was observed in CRS, especially in eosinophilic CRS with nasal polyps (ECRSwNP), with P=0.001. hdWGCNA revealed that the "yellow module" was closely related to basal and suprabasal cells in CRS. Univariate logistic regression and LASSO algorithm selected 13 key genes ( CTSC, LAMB3, CYP2S1, TRPV4, ARHGAP21, PTHLH, CDH26, MRPS6, TENM4, FAM110C, NCKAP5, SAMD3, and PTCHD4). Based on these 13 genes, an effective CRS diagnostic model was developed using various machine learning algorithms (AUC=0.958). Mendelian randomization analysis indicated a causal relationship between CTSC and CRS (inverse variance weighted: OR=1.06, P=0.006), and colocalization analysis confirmed shared genetic variants between CTSC and CRS (PPH4/PPH3>2). Molecular docking results showed that acetaminophen binded well with CTSC (binding energy:-5.638 kcal/mol). Immunofluorescence staining experiments indicated an increase in CTSC +cells in CRS. Conclusion:This study integrates various bioinformatics methods to identify key cell types and genes in CRS, constructs an effective diagnostic model, underscores the critical role of the CTSC gene in CRS pathogenesis, and provides new targets for the treatment of CRS.
