ABSTRACT
Objective:To analyze the distribution characteristics of traditional Chinese medicine (TCM) syndromes in patients with coronavirus disease 2019 (COVID-19) in plateau areas, and to provide theoretical basis for further clinical treatment of patients with COVID-19.Methods:From August 9 to August 24, 2022, patients with COVID-19 admitted to the Third People's Hospital of Tibet Autonomous Region (designated hospital for COVID-19) were included, and their baseline characteristics (age, gender, source), clinical classification and distribution of TCM syndrome types were collected and analyzed. Data analysis was performed using SPSS 26.0 statistical software.Results:A total of 161 COVID-19 patients were enrolled with ethnic distribution: 124 (77.02%) Tibetans, 35 (21.74%) Han, and 2 (1.24%) Hui, 68 males and 93 females. The male-to-female ratio was 0.73∶1. Aged 1 to 94 years, the average age was (39.06±23.64) years old, of which 4 patients were under 1 year old (excluded because the information was missing). A total of 157 patients were enrolled, and 124 patients (78.9%) were under 60 years old, including 120 cases of common type, 4 cases of severe type, 0 cases of critical type, 7 cases over 80 years old, 1 case over 90 years old, and 32 cases under 18 years old. The clinical manifestations of the patient are mainly cough, expectoration, fever, aversion to cold, dry throat, headache, fatigue, running nose, dry mouth, bitter mouth, etc. Most of the tongue is pale, red, and white greasy moss or thin white coating. In TCM, the most common syndrome was cold-dampness blocking lung syndrome (99 cases, 63.06%), followed by cold-dampness stagnant lung syndrome (22 cases, 14.01%), damp-heat accumulating lung syndrome (22 cases, 14.01%), and humidity stagnant lung syndrome (11 cases, 7.01%). Syndromes of epidemic (2 cases, 1.27%), epidemic toxins blocking the lung pattern (1 cases, 0.64%), toxins with dryness intense heat in both qi and ying phases pattern (0 cases) accounted for less than 2%, and the distribution of various syndrome types in COVID-19 patients was uneven ( χ2 = 0.48, P < 0.05). Conclusion:The most common TCM syndromes of COVID-19 patients in Lhasa are cold-dampness blocking lung syndrome, followed by cold-dampness stagnant lung syndrome, damp-heat accumulating lung syndrome, and humidity stagnant lung syndrome.
ABSTRACT
Objective:To evaluate the safety and efficacy of endoscopic super-hemorrhoidal banding (SHB) in the treatment of internal hemorrhoids with prolapse.Methods:From June 2019 to June 2020, a total of 112 patients with grade Ⅱ and Ⅲ internal hemorrhoids underwent endoscopic SHB at People′s Hospital of Qiandongnan Miao and Dong Autonomous Prefecture. The efficacy of SHB, intraoperative and postoperative complications associated with the operation and patients′ satisfaction were prospectively studied. The follow-up time was over six months.Results:A total of 112 patients received SHB for internal hemorrhoids, 74 patients (66.1%) with grade Ⅱ hemorrhoids and 38 patients (33.9%) with grade Ⅲ hemorrhoids. The operations were successfully performed in all patients. No anal pain or bleeding was reported during the operation. All patients experienced various degrees of anal bulge after the operation, which lasted for 2-24 hours before spontaneous disappearance. Five patients with grade Ⅲ internal hemorrhoids showed dysuria, which was relieved with local heat on the bladder. One patient with grade Ⅲ internal hemorrhoid had bloody stool on day 14. The bleeding was stopped with another banding at the site of bleeding ulcer. All patients completed the follow-up. No complications such as bleeding, pain, infection or stenosis occurred in one month after operation. Eighteen patients with grade Ⅲ had partial prolapse after operation without bleeding or other symptoms. Six of them received additional SHB treatment and prolapse disappeared. No postoperative complications occurred in the six months of follow-up in all patients. The satisfaction rate was 100.0% according to the survey.Conclusion:Endoscopic SHB is an effective, safe and simple technique for internal hemorrhoids with prolapse.
ABSTRACT
Objective To study the rule of Apaf-1 in wnt/β-catenin signaling pathway and its regulatory expression mechanism in hepatocellular carcinoma cells.Methods The regulatory mechanism of Apaf-1 gene in Wnt/β-catenin signaling pathway was verified by the TOPflash experiment;real-time PCR was used to detect the expression amounts of Apaf-1 in various hepatoma cell lines (HepG2,H HCC,HB611) and normal liver cell line(LO2);the RNAi interference plasmid of Apaf-1 was constructed and transfected into the HepG2 cell line.Then the transfection efficiency and expression of related genes and proteins were detected.Results The TOPFlash experiment found that Apaf-1 gene could inhibit the wnt/β-catenin signal pathway in a dose dependent manner;the Apaf-1 expression level in hepatoma cells was decreased compared with the normal liver cells,moreover its expression level was lowest in HepG2 cell line;RNA interfering Apaf-1 gene in HepG2 cell line,the expression level of Apaf-1 gene was significantly decreased,and the expression levels of downstream genes and protein(β-catenin,Cyclin A,CDK2,wnt5a,STAT3,EGFR,APC) in wnt signal pathway were significantly increased or decreased,the difference was statistically significant(P＜0.05).Conclusion Apaf-1 gene plays an important role in the formation process of hepatocarcinoma cells by wnt/β-catenin signaling pathway.
ABSTRACT
Objective To study the changes of diamine oxidase (DAO)levels in neonates with hypoxic -is-chemic encephalopathy (HIE)treated with selective brain hypothermi,also to further evaluate Scores for Newborn Gastrointestinal Functior (SNGF).Methods 60 newborns with moderate and severe HIE who were in the NICU of our department from June 2013 to December 2014 were collected.The 60 newborns were randomly divided into hypo-thermia treatment group (HG)and conventional treatment group(CG).The serum was collected and ELISA method was used to test the consistency of DAO on admission and 7 days afterwards,respectively.Meanwhile,the SNGF level of the two groups at the two time points was compared.Results Neither the DAO and SNGF level of the two groups had statistical difference on admission(all P >0.05).Seven days later,both the DAO of the two groups and the SNGF decreased[(12.51 ±1.53)u/mL vs (7.88 ±1.87)u/mL,however,the variation of the hypothermia treatment group was apparently more significant than the change of the conventional treatment group(P =0.011).The SNGF scores of the two groups all decreased,while the hypothermia treatment group was significantly lower than the conventional treat-ment group,the difference were statistically significant (P =0.044,0.006,0.013).Besides,there was remarkably positive correlation between serum DAO level and SNGF (r1 =-0.825,r2 =-0.876,all P <0.05).Conclusion Hypothermia treatment could effectively reduce the injury of asphyxia neonatal gastrointestinal tract by inhibiting the level of DAO,thus improve the gastrointestinal function.
