Objective:To investigate the clinical application value of injection of indocyanine green(ICG)via vasopuncture in fluorescence laparoscopic radical prostatectomy(FLRP).Methods:We retrospectively analyzed the clinical data on 50 cases of PCa treated by injection of ICG via vasopuncture in FLRP.The patients were aged(70.60±5.67)years old,with an average PSA value of(18.42±2.69)μg/L.During the operation,we injected ICG at 0.5 ml by vasopuncture through the vas deferens at each side of the scrotum,observed the visualized images of the vas deferens and seminal vesicles using normal high-definition,black-and-white fluorescence,green fluorescence,and color fluorescence respectively,and then isolated the adherent seminal vesicles under the laparoscope.Results:A total of 93 injections of ICG were completed,86 bilaterally,4 on the right and 3 on the left.The vas defer-ens and seminal vesicles were visualized in 41 cases(60 sides,64.52%),19 bilaterally,7 on the right and 15 on the left.Spillage of the fluorescent agent occurred in 9 cases during the incision of the bladder neck and adhesion of the seminal vesicles was found intra-operatively in 10 cases,in which the seminal vesicles were all quickly located by fluorescence visualization.No rectal injury occurred during the surgery.Mild scrotal subcutaneous bruises were observed in 2 cases,with a postoperative pathological Gleason's score of 7.44±0.88.Conclusion:Injection of ICG by vasopuncture is minimally invasive and safe.ICG-mediated near-infrared imaging and real-time fluorescence imaging of the vas deferens and seminal vesicles can achieve precise positioning and removal of the seminal vesicles and prostate gland without causing rectal injury.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

OBJECTIVE: To observe the clinical efficacy of Miao medicinal crossbow acupuncture therapy as adjuvant treatment for lung cancer pain based on oxycodone hydrochloride extended-release tablet. METHODS: A total of 60 patients with lung cancer pain were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases). In the control group, oxycodone hydrochloride extended-release tablet was given orally, 10 mg a time, once every 12 hours. On the basis of the treatment in the control group, Miao medicinal crossbow acupuncture therapy was applied once every other day in the observation group. The treatment of 14 days was required in the two groups. Before and after treatment, the numerical rating scale (NRS) score, number of break-out pain and Karnofsky performance status (KPS) score were observed in the two groups. The equivalent oxycodone consumption and rate of adverse reactions were recorded, the analgesic effect was evaluated in the two groups. RESULTS: Compared before treatment, the NRS scores and number of break-out pain were decreased while the KPS scores were increased after treatment in the two groups (P<0.01). After treatment, the NRS score and number of break-out pain in the observation group were lower than the control group (P<0.01), the KPS score in the observation group was higher than the control group (P<0.05). The equivalent oxycodone consumption of whole course and the rate of adverse reactions i.e. constipation, drowsiness, nausea and vomiting in the observation group were lower than the control group (P<0.05). The analgesic effect rate was 93.1% (27/29) in the observation group, which was superior to 63.3% (19/30) in the control group (P<0.05). CONCLUSION On the basis of oxycodone hydrochloride extended-release tablet, Miao medicinal crossbow acupuncture therapy as adjuvant treatment can effectively relieve the pain degree, reduce the number of break-out pain and improve the health status and quality of life in patients with lung cancer pain, enhance the efficacy of medication and reduce its adverse reactions.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Applying Chinese medicine (CM) is an important strategy for malignant tumor treatment in China. One of the significant characteristics of CM is to treat diseases based on syndrome differentiation. For Western medicine, it is of important clinical significance to formulate guidelines for the diagnosis and treatment of cancer patients based on the characteristics of disease differentiation. In Chinese clinical practice, the combination of disease differentiation and syndrome differentiation is an important feature for cancer treatment in the past. Currently, molecular profiling and genomic analysis-based precision medicine optimizes the anticancer drug design and holds the greatest success in treating cancer patients. Therefore, we want to know which populations of cancer patients can benefit more from CM treatment if the theory of precision medicine is applied to CM clinical practice. So, we developed a novel diagnostic and therapeutic strategy "disease-syndrome differentiation-genomic profiling-prescriptions" for cancer patients by CM syndrome differentiation and precision medicine. As a result, this strategy has greatly enhanced the anti-tumor efficacy of CM and improved clinical outcomes for cancer patients with some gene mutations. Our idea will hopefully establish a novel approach for the inheritance and innovation of CM.

Chronic stress is generally accepted as the main risk factor in the development of cognitive decline; however, the underlying mechanisms remain unclear. Previous data have demonstrated that the levels of homocysteine (Hcy) are significantly elevated in the plasma of stressed animals, which suggests that Hcy is associated with stress and cognitive decline. To test this hypothesis, we analyzed the cognitive function, plasma concentrations of Hcy, and brain-derived neurotropic factor (BDNF) levels in rats undergoing chronic unpredicted mild stress (CUMS). The results showed that decreased cognitive behavioral performance and decreased BDNF transcription and protein expression were correlated with hyperhomocysteinemia (HHcy) levels in stressed rats. Diet-induced HHcy mimicked the cognitive decline and BDNF downregulation in the same manner as CUMS, while Hcy reduction (by means of vitamin B complex supplements) alleviated the cognitive deficits and BDNF reduction in CUMS rats. Furthermore, we also found that both stress and HHcy disturbed the DNA methylation process in the brain and induced DNA hypermethylation in the BDNF promoter. In contrast, control of Hcy blocked BDNF promoter methylation and upregulated BDNF levels in the brain. These results imply the possibility of a causal role of Hcy in stress-induced cognitive decline. We also used ten-eleven translocation (TET1), an enzyme that induces DNA demethylation, to verify the involvement of Hcy and DNA methylation in the regulation of BDNF expression and the development of stress-related cognitive decline. The data showed that TET1-expressing viral injection into the hippocampus inhibited BDNF promoter methylation and significantly mitigated the cognitive decline in HHcy rats. Taken together, novel evidence from the present study suggests that Hcy is likely involved in chronic stress-induced BDNF reduction and related cognitive deficits. In addition, the negative side-effects of HHcy may be associated with Hcy-induced DNA hypermethylation in the BDNF promoter. The results also suggest the possibility of Hcy as a target for therapy and the potential value of vitamin B intake in preventing stress-induced cognitive decline.

Objective: To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE)-hepatic arterial infusion chemotherapy (HAIC)-targeted-immune quadruple therapy in patients with intermediate and advanced-stage hepatocellular carcinoma (HCC). Methods: 101 patients with intermediate and advanced stage HCC were enrolled according to the inclusion and exclusion criteria, and then they were divided into a combination group and a control group. Patients in the combination group was treated with TACE-HAIC-targeted-immune quadruple therapy, while the control group was only treated with TACE therapy. The overall survival (OS), progression-free survival (PFS), and treatment-related adverse reactions were statistically analyzed in the two groups of patients. Statistical analysis was carried out by t-test, χ² test, rank sum test, Kaplan-Meier curve, log-rank test, Cox regression (or proportional hazards model) analysis according to different data. Results: The tumor objective response rate and disease control rate as evaluated by mRECIST 1.1 criteria in the combination group were 80% and 94%, respectively, which were significantly higher than those in the control group, 41.2% (P<0.001) and 74.5% (P=0.007). The OS and PFS of the combination group were 15.6 months [95%CI 11.3-NA ] and 8.8 months [95%CI 6.9-12.0], respectively, which were significantly better than the control group at 6.1 months [95%CI 5.3-6.6] (P<0.001) and 3.2 months [95%CI 3.0-3.6] (P<0.001). Gastric ulcer incidence was significantly higher in the combination group (9/50, 18%) than that in the control group (2/51, 3.9%) (P=0.023). Conclusion TACE-HAIC-targeted-immune quadruple therapy is a more effective treatment mode for intermediate and advanced-stage HCC than TACE alone, and attention should be paid to the monitoring of target immune-related adverse reactions.

Purpose: The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. Materials and Methods: A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. Results: Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. Conclusion LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

Objective:To study the clinical efficacy of Chaihu Shugansan on non-alcoholic fatty liver（NAFLD） patients with liver stagnation and spleen deficiency syndrome and its effect on intestinal flora. Method:The study was a single-center， randomized，single-blind， placebo-controlled clinical study involving 80 patients with NAFLD treated from January 2019 to January 2020 at our hospital. They were divided into two groups （Chaihu Shugansan group，n=40） and control group （placebo group，n=40）. The two groups of patients were given lifestyle intervention as the basic protocol. The treatment group was orally given Chaihu Shugansan，and the control group was orally given placebo. The drugs were given twice in the morning and evening， 1 dose/time. Patients were followed up for 12 weeks. Before and after treatment，the efficady on liver steatosis was observed by abdominal ultrasound and transient elastography （Fibroscan）， levels of alanine aminotransferase（ALT），aspartate aminotransferase（AST），glutamyl transpeptidase（γ-GT），high density lipoprotein cholesterol（HDL-C），low density lipoprotein cholesterol（LDL-C），total cholesterol（TC），triglyceride（TG），interleukin（IL）-6，IL-1β，Toll-like receptor-4（TLR-4） in peripheral blood mononuclear cells（PBMCs） and intestinal flora were also detected. Result:There were 37 patients in the treatment group and 35 patients in the control group who finally completed the study protocol. The total effective rate of NAFLD in the treatment group（81.08%，30/37） was higher than that in the control group （68.57%，24/35）（Z=2.67，P<0.05）. The treatment group was superior to the control group in reducing the levels of BMI，ALT，AST，TC，LDL-C，TG，γ-GT and increasing the level of HDL-C（P<0.05）. The levels of pro-inflammatory cytokines（TNF-α，IL-1β and IL-6），the values of Controlled Attenuation Parameter（CAP），Liver Stiffness Measurement（LSM） and expression of TLR4 were down-regulated in the treatment group （P<0.01）. In addition，the treatment group showed increase in the abundance of beneficial bacteria （Bifidobacterium and Lactobacillus） and inhibited the abundance of pathogenic bacteria （Enterobacter and Enterococcus） in the gut（P<0.01）. Conclusion:In addition to the lifestyle intervention，Chaihu Shugansan can improve lipid metabolism and liver function，regulate intestinal flora and inhibit the level of inflammatory factors in patients with NAFLD.

Objective:To summarize the infective characteristics of Fournier's gangrene (FG) and evaluate the effect of negative pressure wound therapy (NPWT).Methods:A retrospective case control study was conducted to analyze the clinical data of 31 patients with FG admitted to Peking University First Hospital from May 2010 to September 2020, including 29 males and 2 females, aged 21-78 years [(55.2±2.0)years]. A total of 29 patients were caused by infectious diseases of the perianal and urinary system, and the rest two patients were caused by vulvar infection and retroperitoneal abscess. A total of 23 patients were treated with NPWT (Group A) and 8 patients were treated with conventional dressing (Group B). Characteristics of pathogen, drug-resistance rate, medical treatment and prognosis for all patients were summarized. The hospitalization duration, numbers of operation and wound healing time were compared between two groups.Results:Monomicrobial infection was identified in 14 patients, while polymicrobial infection in 15 patients, fungal infection in 1 and culture-negative in 1. Escherichia coli, Enterococcus faecalis, Enterococcus faecium, Klebsiella pneumoniae and Staphylococcus haemolyticus were the most common pathogenic bacteria. The resistance rate of gram-negative bacilli to third-generation cephalosporins was 37%. Staphylococcus haemolyticus were methicillin-resistant Staphylococcus. The carbapenem antibiotics combined with vancomycin antibiotics were used for all patients as the empirical anti-infection treatment. Three patients died, and the rest 28 patients were followed up for 3 to 12 months [(10.8±2.6)months] after discharge. All the wounds were healed well without recurrence. In Group A and Group B, the hospitalization duration was (37.4±15.0)days and (47.0±16.0)days, respectively ( P>0.05); the number of operation was 3(3, 6) times and 13(4, 17)times, respectively ( P<0.05); the wound healing time was (38.9±17.8)days and (61.8±14.2)days, respectively ( P<0.05). Conclusions:Enterobacteriaceae, Enterococcus and Staphylococcus haemolyticus are the most common pathogenic bacteria for FG, among which the proportion of drug-resistant bacteria is relatively high. NPWT is an effective adjuvant therapy for wound management with reduced operation times and short wound healing time compared to conrentional method.
