ABSTRACT

As a classic prescription for invigorating spleen and replenishing qi, Sijunzi Decoction has a good clinical efficacy in the treatment of gastric cancer. It can improve chemotherapy resistance, reduce the toxic and side effects of chemotherapy, promote postoperative recovery, enhance immunity, improve the nutritional status of patients, improve the quality of life of patients and prevent precancerous lesions. Network pharmacology studies have shown that Sijunzi Decoction exerts anti-gastric cancer effects through multiple active ingredients, multiple targets and multiple pathways, and quercetin may be the main active component in Sijunzi Decoction to exert anti-gastric cancer effects. The main mechanisms of Sijunzi Decoction in the treatment of gastric cancer include regulating the expression of cell cycle and apoptosis-related gene proteins, and inhibiting the proliferation, migration, invasion and gastric cancer stem cell characteristics of gastric cancer cells.

ABSTRACT

Objective:To investigate the efficacy of endoscopic histoacryl injection in cirrhotic patients with newly-developed esophagogastric varices (EGV) who have previously undergone splenectomy combined with pericardial devascularization.Methods:From January 2015 to January 2020, 125 cirrhotic patients with EGV treated with endoscopic histoacryl injection at the Department of Gastroenterology, Jinling Hospital, Medical School of Nanjing University, were included in the retrospective analysis. There were 45 patients in the group of splenectomy combined with pericardial devascularization (splenectomy group for short) and 80 patients in the non-splenectomy group. The efficacy of endoscopic treatment, postoperative variceal improvement, rebleeding rate, and complications were analyzed between the two groups.Results:Endoscopic histoacryl injection was successfully completed in all 125 patients, and the median volume of histoacryl was 4.5 mL. The overall effective rate in splenectomy and non-splenectomy group was 80.0% (36/45) and 57.5% (46/80), respectively. The difference in the number of significantly effective, effective, and ineffective cases between the two groups was statistically significant (16, 20, 9 cases, and 20, 26, 34 cases, respectively, χ 2=6.469, P=0.039). Two and 14 patients developed rebleeding in the splenectomy group and non-splenectomy group, respectively; and the difference in the rebleeding rate between the two groups was statistically significant (4.4% VS 17.5%, Log-rank P=0.039). No patient died within 1 year in either group, and no serious complications such as ectopic embolism occurred. Conclusion:After splenectomy combined with pericardial devascularization in cirrhotic patients with EGV and hypersplenism, the application of histoacryl has better short-term efficacy and can significantly reduce the rebleeding rate compared with the non-splenectomy group.

ABSTRACT

Objective@#To evaluate health risks of five heavy metals in drinking water of rural schools in Henan Province, so as to provide scientific basis for drinking water safety in rural schools.@*Methods@#Totally 1 269 drinking water samples were collected and analyzed for five heavy metals (As, Cd, Cr 6+ , Pb, Hg) concentration in 106 cities and counties of Henan Province, and its spatial distribution characteristics were explored by geographic information system (GIS). Risk assessment method recommended by the United States Environmental Protection Agency (U.S. EPA) was applied to evaluate health risks from five heavy metals through oral ingestion.@*Results@#The qualified rate of As concentration was 100%, and the qualified rates of Cd, Cr 6+ , Pb and Hg were 99.9% , 99.9%, 99.5%, 99.6%. The highest carcinogenic risk was As (3.05×10 -5 ), followed by Cr 6+ (2.73×10 -5 ), and the highest non carcinogenic risk was As (0.158 3), followed by Pb(0.041 7). The carcinogenic risk and non carcinogenic risk were all higher in girls than boys. The carcinogenic and non carcinogenic risks were differences in different regions( P <0.05).@*Conclusion@#Health risks of five heavy metals in drinking water for rural schools in Henan Province were within the acceptable risk level recommended by EPA. As, Cr 6+ and Pb were the main health risk factors in drinking water, and that might impact negatively the healthy growth of primary and middle school students. These should be future efforts of drinking water safety management.

ABSTRACT

Objective:To study the effect of sacubitril valsartan sodium tablets on serum tenascin-C (TN-C) level and myocardial remodeling in patients of chronic left heart failure (CHF) complicated with renal failure.Methods:A total of 84 patients with chronic left heart failure complicated with renal failure admitted to Qinhuangdao Jungong Hospital from October 2020 to October 2021 were included and divided into the observation group (treated with sacubitril valsartan sodium tablets) and the control group (treated with valsartan), with 42 cases in each group according to the random number table method. The clinical efficacy of the two groups was compared after 3 months of treatment. The TN-C level and cardiac function index left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), troponin T (cTnT) and other index before the treatment and after 3 months of treatment were compared between the two groups.Results:After 3 months of treatment, the total effective rate between the two groups had no significant difference ( P>0.05). After 3 months of treatment, the TN-C level in the observation group was lower than that in the control group: (32.42 ± 4.22) μg/L vs. (37.32 ± 4.86) μg/L; and the LVEF in the observation group was higher than that in the control group: (41.21 ± 5.39)% vs. (37.76 ± 5.45)%, the differences were statistically significant ( P<0.05). The LVEDD and cTnT in the two groups had no significant differences ( P>0.05). After 3 months of treatment, neuroendocrine factors norepinephrine, aldosterone, angiotensin Ⅱlevels in the in the observation group were lower than those in the control group: (1 668.60 ± 251.19) pmol/L vs. (2 005.86 ± 280.91) pmol/L, (246.97 ± 13.99) ng/L vs. (275.41 ± 19.38) ng/L, (99.68 ± 8.57) ng/L vs. (112.20 ± 9.52) ng/L, the differences were statistically significant ( P<0.05). Conclusions:Sacubitril valsartan sodium tablets have a good effect in the treatment of CHF complicated with renal failure, which can improve the cardiac function and inhibit the over-activation of neuroendocrine hormones.

ABSTRACT

A 53-year-old man was admitted to the hospital for verrucous hyperplasia on the circular sulcus for 2 years as well as erythematous painful swelling, ulcer and rupture of inguinal lymph nodes for more than 2 months. Physical examination revealed erythematous, indurated and painful swelling of bilateral inguinal lymph nodes. Fluctuation could be felt at the centre of the right swollen inguinal lymph nodes, where several pores were seen with yellowish-white purulent fluid flowing out, giving the appearance of a watering can. Multiple swollen or ulcerative lymph nodes were separated by the inguinal ligament forming the groove sign.There were irregular, indurated, verrucous, proliferative and keratinized lesions sized 1 cm × 2 cm on both sides of the circular sulcus. The right scrotum was obviously swelling. Erythematous, fluctuating swelling, ulcer and rupture of the glans fraenum were also observed with yellowish-white purulent exudates. Neither the secretion from the skin lesions on the surface of bilateral inguinal lymph nodes nor the puncture sample from the right groin was positive for multiple fungal or bacterial culture, acid-fast stain or first culture of C. trachomatis.However, the endogenous plasmid of Chlamydia was successfully amplified by PCR from these samples, and restriction fragment length polymorphism (RFLP) analysis of the major outer membrane protein (MOMP) suggested that the genotype of the Chlamydia strain was L3. Western blot revealed the presence of anti-MOMP antibodies and anti-Pmp H antibodies (titer: > 1: 800) in serum. Culture of C. trachomatis also gave positive results after multiple passage. Biopsy of the verrucous hyperplasia on the right groin is consistent with well-differentiated squamous cell carcinoma of the skin. A diagnosis of lymphogranuloma venereum complicated by cutaneous squamous cell carcinoma was made.

ABSTRACT

Objective To investigate the relationship between polymorphism of arylamine N-acetyltransferase 2 (NAT2) and hair dye dermatitis in a Chinese population. Methods Polymorphism chain-restriction fragment length polymorphism (PCR-RFLP) was used and the wild-type allele (NAT2 * 4) and three mutant alleles (NAT2 * 5A, 6B and 7A) were determined in 60 patients with hair dye dermatitis and 73 age-matched control subjects in Tianjin region. Results In hair dye dermatitis cases, the frequency of NAT2 * 4, NAT2 * 5A, NAT2 * 6B, NAT2 * 7A was 52. 5 % , 5. 0 % ,26.7 % and 15. 8 %, respectively, and no statistically significant difference of the frequencies was found between the hair dye dermatitis patients and controls (P>0. 05). The frequency of rapid genotype, intermediate genotype and slow genotype was 26. 7 % , 51. 7 % and 21. 7 % in hair dye dermatitis cases, 30. 1 %, 50. 7 % and 19. 2 % in control subjects, respectively, and no statistically significant difference of the frequencies between the two groups (P>0. 05). Conclusions Our study suggests that there might be no relationship between polymorphism of NAT2 and genetic susceptibility to hair dye dermatitis in a Chinese population.
