		                        			Objective:To investigate the application of virtual reality (VR) technology on intraoperative pain in patients undergoing peritoneal dialysis (PD)-related procedures with local infiltration anesthesia and the satisfaction.Methods:It was a single-center, prospective, concurrent controlled study. Patients were divided into two groups: VR group and control group. In the VR group, patients wore a VR headset to watch soothing audio and video content during surgery, while the control group underwent routine procedures. Intraoperative pain and satisfaction were assessed using the visual analog scale (VAS) and a 5-point satisfaction scale within 30 minutes of surgery. In addition, tolerance of the VR experience in the VR group was assessed using the VR sickness questionnaire.Results:A total of 43 patients were included in the study, including 25 males (58.1%). Chronic glomerulonephritis [17 cases (39.5%)] and diabetic nephropathy [6 cases (14.0%)] were the main primary diseases. There were 23 cases in the control group and 20 cases in the VR group. There were no significant differences between the two groups in age, sex ratio, proportion of primary disease, diabetes, hypertension, distribution of operation methods, preoperative vital signs and operation time (all P>0.05). VAS pain score was significantly lower in the VR group than that in the control group (5.90±2.38 vs. 7.43±1.67, t=2.469, P=0.018). The percentage of patients who were satisfied was 89.5% (17/19) in the VR group and 78.3% (18/23) in the control group, but there was no significant difference (chi-square test for continuity correction, χ2=0.308, P=0.579). Three patients in the VR group withdrew from the study due to severe discomfort, while the remaining participants found the VR experience to be tolerable. Common adverse effects included fatigue and blurred vision. Conclusions:The application of VR technology in PD-related procedures has been effective in reducing intraoperative pain when combined with local infiltration anesthesia. Furthermore, the utilization of VR technology in PD-related procedures is associated with a safe and tolerable outcome, despite the observation of some adverse effects.

		                        			ObjectiveTo observe the therapeutic effect of Chaishao Longmu decoction on insomnia in the patients with the syndrome of live depression and spleen deficiency and explore the correlation between infrared thermal imaging and insomnia with liver depression and spleen deficiency. MethodA total of 72 insomnia patients treated in the outpatient department of Shenzhen Hospital of Guangzhou University of Chinese Medicine (Futian) from May to December in 2022 were selected and randomized into a treatment group and a control group, with 36 patients in each group. The patients in the treatment group were treated with Chaishao Longmu decoction and those in the control group with eszopiclone for 4 weeks. The clinical efficacy, Pittsburgh sleep quality index (PSQI) score, TCM syndrome score and infrared thermal imaging characteristics [temperature and temperature changes of frontal sleep line, frontal region, anterior trunk, Zhongwan (CV12), conception vessel (CV), left hypochondrium, right hypochondrium, dorsal trunk, and governor vessel (GV)] of two groups were determined before and after treatment. ResultAfter treatment, the clinical response rate in treatment group was 91.67% (33/36), which was higher than that (66.67%, 24/36) in the control group (Z=-2.617, P<0.01). The treatment in both groups decreased the PSQI score and TCM syndrome score (P<0.01), and the decreases were more significant in treatment group than in the control group (P<0.01). After treatment, the total response rate of sleep line improvement in the treatment group was 86.11% (31/36), which was higher than that (66.67%, 24/36) in the control group (Z=-2.591, P<0.05). The frontal temperature of the two groups decreased (P<0.01) after treatment. Compared with those before treatment, the temperatures of anterior trunk, CV12, CV, left hypochondrium, right hypochondrium, dorsal trunk, and GV rose after treatment (P<0.01). After treatment, the treatment group had lower frontal temperature and higher temperatures of anterior trunk, CV12, CV, left hypochondrium, right hypochondrium, dorsal trunk, and GV than the control group (P<0.01). The treatment in the treatment group reduced the ∆T values of GV (P<0.01) and increased that of the CV12, CV, left hypochondrium, and right hypochondrium (P<0.05,P<0.01). The treatment in the control group increased the ∆T value of CV12 (P<0.01). After treatment, the treatment group had lower ∆T values of GV (P<0.01) and higher ∆T value of CV12, CV, left hypochondrium, and right hypochondrium (P<0.05, P<0.01) than the control group. Compared with that before treatment, the temperature difference between GV and CV in the two groups increased after treatment (P<0.01). According to the infrared thermal image characteristics, the normal temperature difference between GV and CV was within the range of 0.5-1. The median value after treatment in the treatment group was 0.69 (0.52, 0.88), which was within the normal range, indicating that the treatment group outperformed the control group. ConclusionChaishao Longmu decoction can alleviate short-term insomnia by soothing liver, invigorating spleen, harmonizing the middle energizer, and regulating GV and CV. With definite clinical effect, this decoction deserves promotion. Furthermore, the frontal temperature, sleep line, CV12, CV ∆T, and temperature difference between GV and CV revealed by the infrared thermal images could be used for the diagnosis and of insomnia with liver depression and spleen deficiency.

		                        			OBJECTIVE To establish a quantitative analysis method for the quality control components in Tenghuang jiangu capsules, and predict the possible action mechanism of the quality control components. METHODS Seven key quality control components in Tenghuang jiangu capsules were quantitatively analyzed by UHPLC-Q-Orbitrap HRMS. The “component-target” network was constructed based on network pharmacology, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and gene ontology (GO) function enrichment analysis were further conducted to find the key signaling pathways. RESULTS The average contents of succinic acid, hyperoside, gallic acid, kaempferol, naringin, naringenin and protocatechuic acid in 20 batches of Tenghuang jiangu capsules were 520.92, 67.67, 129.48, 4.74, 397.45, 5.66 and 376.62 μg/g, respectively. The results of network pharmacology showed that the 62 key target genes of the quality control components of the drug included AKT1, TNF, VEGFA, MMP9, PTGS2, etc. They were mainly enriched in cytokine receptor interaction, nuclear factor, tumor necrosis factor, interleukin 17, rheumatoid arthritis, Toll-like receptor and other signal pathways, involving inflammatory reaction, signal transduction, protein phosphorylation and other biological processes, kytoplasm, cell membrane and other cell components, as well as enzyme activity, energy activity and other molecular functions. CONCLUSIONS The established UHPLC- Q-Orbitrap HRMS method can be used for the quantitative analysis of the quality control components of Tenghuang jiangu capsule. Its quality control components may be mapped to inflammatory pathways related to bone diseases such as rheumatoid arthritis and Toll-like receptors through AKT1, TNF, VEGFA and other key targets, so as to play a therapeutic role.

		                        			Objective:To summarize the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) infected with Delta variant, so as to provide further references for clinical diagnosis and treatment.Methods:A real-world study was conducted to analyze the characteristics of 166 COVID-19 patients infected with Delta variant at Guangzhou Eighth People’s Hospital, Guangzhou Medical University.Results:The study enrolled 5 asymptomatic cases, 123 non-severe cases (mild and moderate type), and 38 severe cases (severe and critical type). Among these patients, 69 (41.6%) were male and 97 (58.4%) were female, with a mean age of 47.0±23.5 years. Thirty-nine cases (23.5%) had received 1 or 2 doses of inactivated vaccine. The incidence of severe COVID-19 cases was 7.7% in 2-doses vaccinated patients, which was lower than that of 11.5% in 1-dose and 26.8% in unvaccinated patients. The proportion of severe cases in 2 dose-vaccinated patients was 7.7%, which was lower than that of 11.5% in 1-dose vaccinated patients and 26.8% in unvaccinated patients, but the difference was not significant ( P>0.05). The most common clinical symptom was fever (134 cases, 83.2%), and 39.1% of cases presented with high-grade fever (≥39 °C); other symptoms were cough, sputum, fatigue, and xerostomia. The proportion of fever in severe cases was significantly higher than that of non-severe cases (97.4% vs. 76.4%, P<0.01). Similarly, the proportion of severe cases with high peak temperature (≥39 ℃) () was also higher than that of non-severe cases (65.8% vs. 30.9%, P<0.01). The median minimal Cycle threshold (Ct) values of viral nucleic acid N gene and ORFlab gene were 20.3 and 21.5, respectively, and the minimum Ct values were 11.9 and 13.5, respectively. Within 48 h of admission, 9.0% of cases presented with decreased white blood cell counts, and 52.4% with decreased lymphocyte counts. The proportions of increased C-reactive protein, serum amyloid A, interleukin 6, and interleukin 10 were 32.5%, 57.4%, 65.3%, and 35.7%, respectively. The proportions of elevated C-reactive protein, serum amyloid A and interleukin-6 in severe cases were significantly higher than those in non-severe cases ( P<0.01). Logistic regression analysis showed that older age and higher peak temperature were associated with a higher likelihood of severe cases ( OR>3, 95% CI: 2-7, P<0.01). In terms of treatment, traditional Chinese medicine (TCM) was used in 97.6% of non-severe cases and 100% in severe cases. Other treatments included respiratory and nutritional support, immunotherapy (such as neutralizing antibodies and plasma of recovered patients). The median times from admission to progression to severe cases, of fever clearance, and of nucleic acid conversion were 5 days, 6 days and 19 days, respectively. No deaths were reported within 28 days. Conclusions:The symptoms of Delta variant infection in Guangzhou are characterized by a high proportion of fever, high peak temperature, long duration of fever, high viral load, a long time to nucleic acid conversion, and a high incidence of severe cases. The severe cases exhibit a higher percentage of elderly patients, a longer duration of fever and have a higher fever rate and a higher hyperthermia rate than non-severe cases. Age and hyperthermia are independent risk factors for progression to severe disease. The combination of TCM and Western medicine can control the progression of the disease effectively.

		                        			Objective:To evaluate the follow-up clinical results of W-shaped acetabular angular plate for the treatment of acetabular posterior wall fractures through a direct posterior approach (DPA).Methods:Fifteen cases (10 males and 5 females, average aged 42.1±10.0 years) were involved in this study, with acetabular posterior wall fractures treated by using the W-shaped acetabular angular plate through a DPA between March 2017 and June 2019. Nine patients with fractures were injured by traffic accidents and the other 6 cases by falling. Based on the three-column classification for acetabular fractures, all of the cases belonged to posterior wall fractures (A2.1), which included 6 cases of simple fractures and 9 cases of comminuted fractures. The mean time interval between injury and surgery was 5.6±1.1 (range, 4-8) days. The DPA was adopted in all cases. The posterior wall fractures of the acetabulum were reduced and fixed with W-shaped acetabular angular plates. The reduction quality of the acetabulum was evaluated by X-ray and CT scan during follow-up visits according to the criteria proposed by Matta. The function of the hip joint was assessed by the Merle d'Aubigné-Posteal score modified by Matta.Results:The length of the surgical incision was 9.5±1.1 (range, 8-12) cm. The operation time was 45.3±10.1 (range, 35-75) mins. The amount of intraoperative blood loss was 248.0±94.7 (range, 100-380) ml. All the patients who were followed up for 20.5±6.3 (range, 16-38) months. All cases were evaluated according to Matta's reduction quality criteria, the satisfactory ratio of reduction was 100%. Among cases, 10 cases were matched the anatomic reduction, and the other 5 cases have belonged to satisfy. All cases of fractures had healed (the mean of healing time was 9.4±1.3 (range, 8-12 weeks). At the final follow-up visit, the mean of modified Merle d'Aubigne-Postel score was 16.9±1.6 (range, 13-18). Excellent clinical outcomes were obtained in 10 cases, good in 3 cases, and fair in 2 cases. One case had deep venous thrombosis of the lower extremities. The clots disappeared after anticoagulation treatment. One case had the heterotopic ossification, Brooker grade I, without any special treatment due to not affecting the hip joint activity in the follow-up visits. One patient had incision fat liquefaction and the wound healed after intensive dressing change. No internal fixation loosening or losing of fracture reduction was found at the follow-up visits.Conclusion:This study shows that using W-shaped acetabular angular plate for the treatment of acetabular posterior wall fractures through the DPA could obtain early satisfactory clinical outcomes.

		                        			Understanding the effect of immunosuppressive agents on intestinal microbiota is important to reduce the mortality and morbidity from orthotopic liver transplantation (OLT). We investigated the relationship between the commonly used immunosuppressive agent cyclosporine A (CSA) and the intestinal microbial variation in an OLT model. The rat samples were divided as follows: (1) N group (normal control); (2) I group (isograft LT, Brown Norway [BN] rat to BN); (3) R group (allograft LT, Lewis to BN rat); and (4) CSA group (R group treated with CSA). The intestinal microbiota was assayed by denaturing gradient gel electrophoresis profiles and by using real-time polymerase chain reaction. The liver histopathology and the alanine/aspartate aminotransferase ratio after LT were both ameliorated by CSA. In the CSA group, the numbers of rDNA gene copies of Clostridium cluster I, Clostridium cluster XIV, and Enterobacteriaceae decreased, whereas those of Faecalibacterium prausnitzii increased compared with the R group. Cluster analysis indicated that the samples from the N, I, and CSA groups were clustered, whereas the other clusters contained the samples from the R group. Hence, CSA ameliorates hepatic graft injury and partially restores gut microbiota following LT, and these may benefit hepatic graft rejection.

		                        			OBJECTIVE:
		                        			To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China.
		                        		
		                        			METHODS:
		                        			The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI.
		                        		
		                        			RESULTS:
		                        			A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI.
		                        		
		                        			CONCLUSIONS
		                        			The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.

		                        			 Objective:
		                        			To evaluate whether the self-designed single-channel intracavitary applicator yields equivalent clinical efficacy and safety to the standard Fletcher-type three-channel applicator in the high-dose-rate (HDR) brachytherapy for uterine cervical cancer.
		                        		
		                        			Methods:
		                        			From December 2011 to April 2017, patients initially diagnosed with cervical cancer were randomly assigned into the external beam radiotherapy (EBRT)+ single-channel intracavitary applicator group (the patent single-channel group) and EBRT+ the Fletcher applicator group. Whole pelvis irradiation was delivered with 6-MV photons via a four-field box variant or anterior and posterior parallel fields. Five to six fractions of intracavitary brachytherapy were performed at a dose of 7 Gy at point A once a week after 30 Gy (BED at point A: 80-90 Gy). Chemotherapy was given with intravenous injection of cisplatin at a dose of 40 mg/m2 once weekly during EBRT.Clinical efficacy and safety were evaluated after the treatment.
		                        		
		                        			Results:
		                        			In total, 150 eligible cases were assigned into the Fletcher applicator group and 149 cases into the patent single-channel group. The short-term clinical efficacy and acute toxicity did not significantly differ between two groups. The response rate was 94.0% in the Fletcher group, and 94.7% in the patent single-channel group. In the Fletcher applicator group, 76(50.7%) patients developed ≥ grade 3 hematologic toxicity and 61(40.9%) in the patent group (
