Objective:To investigate the effects of metronidazole and vulvar cleaning with 0.1% benzalkonium bromide solution on vaginal environment, etiology, and interleukin-6 and Toll-like receptor 2 levels in lavage fluid of patients with bacterial vaginosis.Methods:A total of 114 patients with bacterial vaginosis who were admitted to Jinan 2 nd People's Hospital from February 2021 to February 2024 were included in this prospective study. These patients were randomly divided into a control group and an observation group, with 57 patients in each group, following a 1:1 ratio. The control group received treatment with metronidazole, while the observation group received metronidazole in combination with vulvar cleaning using a 0.1% benzalkonium bromide solution, for a total of 14 days. The clinical efficacy was evaluated by comparing the vaginal environment (including vaginal pH, cleanliness, and microbial density), microbiological outcomes (lactobacilli detection rate and pathogenic bacteria detection rate), and interleukin-6 and Toll-like receptor 2 levels in the vaginal lavage fluid between the two groups before and after treatment. Adverse drug reactions were recorded. Patients were followed up for 3 months after treatment to record recurrence rates. Results:The total response rate in the observation group was significantly higher than that in the control group [92.98% (53/57) vs. 78.95% (45/57), χ2 = 4.65 P < 0.05]. After treatment, improvements of vaginal pH, vaginal cleanliness, and bacterial density were greater in the observation group than those in the control group ( χ2 = 4.61, Z = 4.92, 4.29, all P < 0.05). After treatment, the detection rate of lactobacilli in the observation group was significantly higher than that in the control group [63.16% (36/57) vs. 42.11% (24/57), χ2 = 5.07, P < 0.05]. The detection rate of pathogenic bacteria in the observation group was significantly lower than that in the control group [5.26% (3/57) vs. 17.54% (10/57), χ2 = 4.25, P < 0.05]. After treatment, lavage fluid levels of interleukin-6 [(8.70 ± 2.13) ng/L vs. (13.52 ± 3.36) ng/L] and Toll-like receptor 2 [(5.06 ± 1.34) ng/L vs. (7.84 ± 1.22) ng/L] in the observation group were significantly lower than those in the control group ( t = 9.15, 11.58, both P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups ( χ2 = 1.37, P > 0.05). After 3 months of treatment, the recurrence rate of bacterial vaginosis in the observation group was significantly lower than that in the control group [4.55% (1/22) vs. 27.78% (5/18), χ2 = 4.19, P < 0.05]. Conclusions:The combination of metronidazole and vulvar cleaning with a 0.1% benzalkonium chloride solution is effective for treating bacterial vaginosis. This approach helps regulate the vaginal environment, increases the levels of lactobacilli, reduces the levels of pathogenic bacteria, and decreases the levels of interleukin-6 and Toll-like receptor 2 in the lavage fluid. Additionally, it decreases the risk of recurrence of bacterial vaginosis and is highly safe.

Objective:To study the treatment efficacy and safety in using needle-grasper assisted single-port laparoscopic hepaticojejunostomy to treat choledochal cysts in children.Methods:The data of 41 patients with choledochal cysts treated at the Department of Pediatric Surgery, the First Affiliated Hospital of Xiamen University and the Second Hospital of Hebei Medical University from January 2018 to December 2021 were reviewed. There were 8 males and 33 females, aged (2.5±1.9) years. These patients were divided into the needle-grasper assisted single-port laparoscopic hepaticojejunostomy group (needle-grasper group, n=21) and the single-port laparoscopic hepaticojejunostomy group (control group, n=20). Operation time, intestinal function recovery time, gastric tube retention time, abdominal drain indwelling time, postoperative hospital stay, and perioperative complications were compared between the two groups. Results:All 21 children in the needle-grasper group underwent successful surgery without any need to convert to conventional laparoscopic or open surgery. The operation time (156.4±21.2) min was significantly shorter than the control group (218.3±28.6) min ( t=2.95, P=0.017). There were no significant differences in intestinal function recovery time, gastric tube retention time, abdominal drain indwelling time, postoperative hospital stay and perioperative complications between the two groups (all P>0.05). Parents were very satisfied with the cosmetic effect of the invisible scar after surgery. Conclusion:Needle-grasper assisted single-port laparoscopic hepaticojejunostomy was safe, reliable and the operation time was shorter than using a single-port to achieve minimally invasive and scarless surgery.

Nutritional treatment of intensive care patients may require an accurate, effective and personalized approach in the future. Using nutritional risk assessment to guide nutritional treatment, factors including timing, energy expenditure and goal, pathway and dosage should be considered. Through testing the individual nutritional molecular markers, the benefits and risks can be evaluated. So nutritional therapy can enhance the nutritional and metabolic status of intensive care patients, and improve clinical outcomes.

Objective To investigate the effect of Glutamine (Gln) on heat stress-induced dysfunction of intestinal epithelial barrier. Methods Human intestinal epithelial Caco-2 cells were pre-incubated with Gln for 24h and then exposed to heat 43℃ for 1h. Cell counting kit-8 (CCK-8) was used to detect the cellular proliferation with various concentrations of Gln and choose an optimum concentration for subsequent experiments. The barrier integrity was measured by transepithelial electrical resistance (TEER) and horseradish peroxidase (HRP) permeability. Levels of tight junction protein occludin and ZO-1 were analyzed by Western blotting. Cytoskeleton using Coomassie blue staining was observed by microscopy. Results At 0.7mmol/L concentration, Gln showed the most effective cell proliferation compared with other concentration groups (P<0.05). Therefore, 0.7mmol/L Gln was used as effective concentration in following experiments. Gln attenuated the TEER decrease and impairment of intestinal permeability induced by heat exposure compared with 43℃ group (P<0.01). The expressions of occludin and ZO-1 were significantly elevated by pretreatment with Gln. The distortion of cytoskeleton was also effectively prevented. Conclusion 0.7mmol/L Gln is potentially beneficial for protecting against heat stress-induced permeability dysfunction and epithelial barrier damage.

Objective To investigate the influence of systematic nursing intervention on family cohesion, adaptability, internet addiction rehabilitation degree and psychological status of patients with internet addiction disorder ( IAD ) . Methods IAD patients were randomly divided into control group ( n=50 ) and experimental group ( n=50) according to random number table. Patients in the control group were intervened by conventional nursing treatment. On the base of that, patients in the experimental group were intervened by systematic nursing intervention mode, such as inspirational education, comment classroom of nursing, systematic health education, regular follow-up, etc. Changes in family cohesion, adaptability, internet addiction rehabilitation degree and psychological status of the IAD patients were evaluated before and three months after the intervention.Results After the intervention, of patients in the experimental group, scores of ideal family cohesion improved from ( 67. 54 ± 4. 58 ) points to ( 74. 63 ± 3. 20 ) points; scores of actual family cohesion improved from (53.14±4.29) to (76.29±3.93); scores of ideal adaptability improved from (46.43±7.98) to (57.50±6.05);scores of actual adaptability improved from (44.90±5.78) to (50.78±5.43);scores of internet addiction rehabilitation degree declined from (83.37±3.46) to (56.01±5.02);various indexes of psychological health status had all improved significantly than before the treatment ( P<0. 05 ) . Indexes of patients in the control group showed no significant improvement (P>0.05).Conclusions Systematic nursing intervention mode can obviously improve physiological and psychological conditions of IAD patients, and increase the rate of internet addiction rehabilitation.

Objective To compare the mRNA expressions of interleukin (IL)-17 and IL-23 in peripheral blood of patients with psoriasis vulgaris versus healthy individuals,assess the relationship of these parameters with psoriasis area and severity index (PASI) score,and to investigate the therapeutic mechanisms of total glucosides of peony (TGP) for psoriasis vulgaris.Methods Fifty patients with psoriasis vulgaris and 40 healthy individuals were enrolled in this study.Of these patients,42 were treated with TGP of 600-900 mg twice a day for 8 weeks.Blood samples were obtained from all the healthy individuals,50 patients before treatment,42 patients after 4-week treatment,and 23 patients after 8-week treatment.Real-time fluorescence-based quantitative reverse transcription PCR (RT-PCR) was used to determine the mRNA expression levels of IL-17 and IL-23 in the blood samples.The severity of psoriasis was evaluated using PASI score before and after the treatment.Statistical analysis was done by t test,rank sum test,and Pearson correlation analysis using the SPSS16.0 software.Results The IL-17 and IL-23 mRNA expression levels (given in △Ct value) in the patients before treatment were significantly higher than those in the healthy controls (IL-17,-5.32 ± 0.80 vs.2.79 ± 0.76,t =47.71,P ＜ 0.05; IL-23,-5.43 ± 0.68 vs.-3.77 ± 0.86,t =10.38,P ＜ 0.05),and positively correlated with the PASI score (r =0.61,0.52 respectively,both P ＜ 0.05).A significant decrease was observed in the mRNA expression levels of IL-17 and IL-23 as well as PASI score in the 42 patients after 4-week treatment with TGP compared with those before treatment(IL-17,-2.24 ± 0.61 vs.-5.30 ± 0.78,t =20.40,P ＜ 0.05; IL-23,-1.97 ± 0.74 vs.-5.44 ± 0.68,t =21.69,P ＜ 0.05; PASI,5.8 ± 2.7 vs.9.4 ± 4.2,t =4.68,P ＜ 0.05),and in the 23 patients after 8-week treatment compared with those after 4-wek treatment(IL-17,-1.51 ± 0.78 vs.-2.21 ± 0.59,t =3.50,P ＜ 0.05; IL-23,-1.27 ± 0.81 vs.-1.89 ± 0.72,t =2.70,P＜ 0.05; PASI,3.8 ± 1.8 vs.7.3 ± 2.5,t =5.47,P＜ 0.05).Conclusions It seems that both IL-17 and IL-23 are involved in the pathogenesis of psoriasis vulgaris,and TGP treatment can reduce the mRNA expression levels of IL-17 and IL-23 as well as PASI score in patients with psoriasis vulgaris.
