Objective: To investigate the preventive and reparative mechanisms of platelet-rich plasma-biodegradable quick setting spray (PRP-BQSS) on solar dermatitis, thereby providing a safe and effective novel therapeutic approach for clinical application. Methods: PRP-BQSS was prepared. A ultraviolet B (UVB)-induced solar dermatitismodel was established in SPF-grade male SD rats. The rats were divided into the prevention experiment (treated with PRP-BQSS, L' Oréal SPF 50+sunscreen, Nature's Hall SPF 50+sunscreen, or saline) and the treatment experiment (treated with PRP-BQSS, Jingwanhong ointment, Green ointment, or saline). The effects were evaluated by measuring epidermal thickness (HE staining) and quantifying the integrated optical density (IOD) of inflammatory cells (CD11b staining). One-way ANOVA and Tukey's HSD test were performed using GraphPad Prism 9.4.0. Results: The PRP-BQSS exhibited significant efficacy in both prevention and repair. In the prevention experiment, the PRP-BQSS prevention group (Group A) showed only mild pale red erythema on the dorsal skin of rats, without significant swelling or desquamation. Histological analysis revealed that epidermal thickness in Group A (36.55±6.58 μm) was comparable to Groups B (L' Oréal, 34.84±6.59 μm) and C (Natural Hall, 34.59±8.20 μm)(P>0.05), but significantly lower than that in Group D (control group, 47.82±11.69 μm). Skin sections from Group A demonstrated intact epidermal structure with clear stratification and no significant inflammatory cell infiltration. The CD11b-positive cell count (24.30±7.43) was significantly lower than that in Group D (33.65±8.47, P<0.05). In the treatment experiment, HE staining of Group A (PRP-BQSS treatment group) showed intact epidermal structure with orderly arrangement of the basal layer, spinous layer, and granular layer, thin and uniform stratum corneum, and regular collagen fiber arrangement. The epidermal thickness of Group A (37.10±6.41 μm) showed no significant difference from Groups B (Jingwanhong ointment group, 38.66±9.07 μm) or C (Green ointment group, 35.72±4.98 μm)(P>0.05), but was significantly lower than that in Group D (control group, 48.35±8.99 μm)(P<0.05). The integral optical density value of CD11b-positive cells in Group A (32.82±11.01) was significantly lower than that in Group D (47.25±13.52, P>0.05). Moreover, the degree of inflammatory infiltration in Group A was relatively lower compared to Group B (37.14±9.20) and Group C (34.32±16.87), suggesting a superior repair capacity. However, the intergroup differences were not statistically significant (P>0.05). Conclusion: PRP-BQSS hydrogel dressing possesses dual preventive and reparative functions. It exerts its effects by reducing CD11b-positive cell infiltration (inflammation suppression) and promoting the orderly arrangement of the basal layer-epidermal layer-granular layer (epidermal reconstruction). This material holds promise as a novel and effective therapeutic approach for the prevention and treatment of solar dermatitis, particularly suitable for high-risk populations such as children, individuals with sensitive skin, and those engaged in outdoor activities.

OBJECTIVE To establish a method for simultaneously determining three anti-tuberculosis drugs in the plasma of patients with spinal tuberculosis and apply it in clinical practice. METHODS LC-MS/MS method was established for the quantitative determination of the concentrations of isoniazid, rifampicin and pyrazinamide in the plasma of patients with spinal tuberculosis, using diphenhydramine as the internal standard. The determination was carried out using Chemalink CM-C18T column, with mobile phase consisting of 0.1% formic acid-methanol solution (gradient elution), at the flow rate of 0.4 mL/min and an injection volume of 2 μL. Multiple reaction monitoring was conducted using an electrospray ionization source in positive ion mode. The ion pairs used for quantitative analysis were m/z 138.0→121.0( for isoniazid), m/z 823.3→791.3( for rifampicin), m/z 124.1→ 79.0 (for pyrazinamide), and m/z 256.0→167.0 (for diphenhydramine). Fifty-three patients diagnosed with spinal tuberculosis in Qinghai Provincial People’s Hospital from January 2023 to June 2025 were selected, and the plasma concentrations of isoniazid, rifampicin and pyrazinamide in these patients were measured using the above method. RESULTS The linear ranges for isoniazid, rifampicin and pyrazinamide were 0.5-16, 2-64, and 2.5-80 μg/mL, respectively (r≥0.998 7). The accuracy ranged from 90.20% to 108.64% (n=5). RSDs for intra-day precision were all less than 6.63% (n=5), while those for inter-day precision were all less than 8.42% (n=3). The matrix effects ranged from 88.60% to 115.41% (n=5). The relative deviations in the stability tests were all within the ±15% range, and the carry-over effect did not interfere with the determination. The results of clinical application showed that the mean plasma drug concentrations of isoniazid, rifampicin and pyrazinamide in patients with spinal tuberculosis were (3.62±2.80), (8.55±4.57), and (20.12±6.56) μg/mL, respectively. The incidences of plasma drug concentrations falling below the effective peak concentrations were 49.06%, 58.49% and 60.38%, respectively. CONCLUSIONS The method established in this study is rapid, accurate, and demonstrates good stability, making it suitable for clinical monitoring of the plasma concentrations of isoniazid, rifampicin and pyrazinamide in patients with spinal tuberculosis.

AIM:To evaluate the clinical efficacy of three types of spectacle lenses with different peripheral microstructure designs in controlling myopia progression among children.METHODS: Retrospective case analysis was conducted. Children diagnosed with myopia aged 6 to 12 y who were received initial spectacle fitting and completed 1-year follow-up at the Optometry Clinic of Suining Central Hospital between January 2023 and August 2024 were enrolled. Only right eye data of all subjects were included for analysis. Based on the type of spectacle lenses independently selected by the children and their parents/guardians, they were divided into four groups: diffusion optics technology(DOT), cylindrical annular refractive element(CARE), highly aspherical lenslets(HAL), and single-vision lenses(SVL). Changes in axial length(AL)and spherical equivalent(SE)from baseline were observed after 1-year lens wear in four groups. Variations between three peripheral microstructure-designed spectacles and single-vision spectacles were compared. The effects of different lens designs on spherical power, astigmatism, corneal curvature, corneal astigmatism, anterior chamber depth, lens thickness, and vitreous cavity depth were analyzed.RESULTS:In this retrospective study, a total of 118 eyes from 118 myopic children were included. There were 28 eyes in 28 children in DOT group [16 males and 12 females, age 10(9, 12)y]. CARE group contained 26 eyes in 26 children, [12 males and 14 females, age 11(9, 12)y]. HAL group had 26 eyes in 26 children [16 males and 10 females, age 10(9, 11)y]. SVL group included 38 eyes in 38 children [20 males and 18 females, age 11(9, 12)y]. There were no significant differences in age, gender, baseline AL, or SE among the four groups(all P>0.05). After 1-year wearing, no increase and slight regression were observed in AL and SE in the DOT group, with no significant differences compared with baseline(all P>0.05). AL and SE increased to varying degrees in the CARE, HAL and SVL groups(all P<0.01). Significant inter-group differences were found in the changes of AL and SE(F=22.820, 30.949, both P<0.001). The mean changes in AL and SE for the DOT group(-0.034±0.180 mm, 0.040±0.243 D)were significantly smaller than those in the CARE group(0.225±0.174 mm, -0.375±0.308 D)and the HAL group(0.147±0.130 mm, -0.255±0.256 D). The changes of AL and SE in the three groups were significantly lower than those in the SVL group(0.355±0.240 mm, -0.891±0.592 D)(all P<0.05).CONCLUSION: In children, short-term wear of spectacles with peripheral microstructural design demonstrates better myopia control efficacy compared to single-vision spectacles. DOT lenses show superior short-term efficacy compared with CARE and HAL lenses.

ObjectiveTo investigate the efficacy and safety of the direct-acting antiviral agents coblopasvir hydrochloride/sofosbuvir (CLP/SOF) regimen used alone or in combination with ribavirin (RBV) in the treatment of patients with genotype 3 hepatitis C virus (HCV) infection in terms of virologic response rate, liver function recovery, improvement in liver stiffness measurement (LSM), and adverse drug reactions, and to provide a reference for clinical medication. MethodsA total of 98 patients with genotype 3 HCV infection who attended The Third People’s Hospital of Kunming from January 2022 to December 2023 were enrolled, and according to the treatment method, the patients were divided into CLP/SOF+RBV treatment group with 55 patients and CLP/SOF treatment group with 43 patients. The patients were observed in terms of rapid virologic response at week 4 (RVR4), sustained virologic response (SVR), previous treatment experience, underlying diseases, laboratory and imaging indicators, and adverse reactions during treatment. The course of treatment was 12 weeks, and the patients were followed up for 12 weeks after drug withdrawal. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the Friedman test was used for comparison within each group at different time points, and the Bonferroni method was used for further comparison and correction of P value; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The univariate and multivariate Logistic regression analyses were used to investigate the influencing factors for SVR12. ResultsBefore treatment, there were significant differences between the CLP/SOF+RBV treatment group and the CLP/SOF treatment group in terms of LSM, total bilirubin (TBil), gamma-glutamyl transpeptidase (GGT), HCV genotype, and the presence or absence of liver cirrhosis and compensation (all P<0.05). The 98 patients with genotype 3 HCV infection had an RVR4 rate of 81.6% and an SVR12 rate of 93.9%. The patients with genotype 3a HCV infection had an RVR4 rate of 84.44% and an SVR12 rate of 97.78%, while the patients with genotype 3b HCV infection had an RVR4 rate of 79.25% and an SVR12 rate of 90.57%. There were significant differences in RVR4 and SVR12 rates between the patients without hepatocellular carcinoma and those with hepatocellular carcinoma, there was a significant difference in RVR4 rate between the patients without HIV infection and those with HIV infection, and there was a significant difference in SVR12 rate between the previously untreated patients and the treatment-experienced patients (all P<0.05). The univariate Logistic regression analysis showed that treatment history, hypertension, hepatocellular carcinoma, ascites, albumin (Alb), and platelet count were influencing factors for SVR12 (all P<0.05), and the multivariate Logistic regression analysis showed that hepatocellular carcinoma (odds ratio=0.034, 95% confidence interval: 0.002 — 0.666, P=0.026) was an independent influencing factor for SVR12. After treatment with CLP/SOF combined with RBV or CLP/SOF alone, the patients with genotype 3 HCV infection showed gradual reductions in the liver function parameters of TBil, GGT, and alanine aminotransferase (all P<0.05) and a gradual increase in the level of Alb (P<0.05). As for renal function, there were no significant changes in blood urea nitrogen and creatinine after treatment (P>0.05). For the patients with or without liver cirrhosis, there was a significant reduction in LSM from baseline after treatment for 12 weeks (P<0.05). Among the 98 patients with genotype 3 HCV infection, 9 tested positive for HCV-RNA at 12 weeks after treatment, 2 showed no response during treatment, 4 showed virologic breakthrough, and 3 experienced recurrence. The overall incidence rate of adverse events during treatment was 17.35% for all patients. ConclusionCLP/SOF alone or in combination with RBV has a relatively high SVR rate in the treatment of genotype 3 HCV infection, with good tolerability and safety in patients during treatment, and therefore, it holds promise for clinical application.

By systematically combing ancient and modern literature, this paper examined Tribuli Fructus and Astragali Complanati Semen(ACS) used in the famous classical formulas from the aspects of name, origin, production area, harvesting and processing, clinical efficacy, so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology, and there were nicknames such as Baijili, Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas, and there were nicknames such as Baijili, Shayuan Jili and Tongjili. Because both of them had the name of Baijili, confusion began to appear in the Song dynasty. In ancient and modern times, the main origin of Tribuli Fructus were Tribulus terrestris, and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu, but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part, harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times, and the plump, firm texture, grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing, while modern commonly used is purified, fried and salt-processed. The ancient records of Tribuli Fructus were spicy, bitter, and warm in nature, with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders, improving vision, promoting muscle growth, and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today, the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed, traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter, followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior, while modern standards prioritize plump, uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying, while modern practice commonly employs purification methods. In terms of medicinal properties, the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus, its effects were thus regarded as equivalent to those of Tribuli Fructus, serving as the medicine for treating wind disorders, additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang, solidify sperm and reduce urine, nourish the liver and brighten the eye, etc. Based on the textual research results, it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials, we should pay attention to the specific reference object of Baijili, T. terrestris and A. complanatus should be identified and selected, and the processing method should be in accordance with the requirements of the formulas.

ObjectiveTo investigate the therapeutic efficacy, influencing factors, and safety of a treatment regimen based on coblopasvir hydrochloride capsules/sofosbuvir tablets in patients with chronic hepatitis C virus (HCV) infection in a real-world setting. MethodsA total of 253 patients who attended The Third People’s Hospital of Kunming from September 1, 2021 to May 31, 2024 were enrolled, among whom there were 86 patients with compensated liver cirrhosis (CLC group) and 167 patients with chronic hepatitis C (CHC group). The patients were treated with coblopasvir hydrochloride capsules (60 mg)/sofosbuvir tablets (400 mg) with or without ribavirin tablets for 12 weeks, and they were followed up for 12 weeks after drug withdrawal. The primary outcome measures were the rate of sustained virologic response at week 12 after treatment (SVR12) and safety, and the secondary outcome measures were the changes in liver function, renal function, blood routine, and liver stiffness measurements (LSM) after 4 weeks of treatment, after 12 weeks of treatment, and at 12 weeks after drug withdrawal. The independent-samples t test and the Mann-Whitney U test were used for comparison of continuous data between two groups, and the Friedman test was used for comparison between multiple groups, while the Bonferroni method was used for paired comparison within each group; the chi-square test was used for comparison of categorical data between two groups. The Logistic analysis was used to investigate related influencing factors. ResultsThe 253 patients with chronic HCV infection had a mean age of 49.38±8.65 years, and there were 151 male patients (59.7%). Of all patients, 33.99% (86/253) had liver cirrhosis, 25.69% (65/253) had hypertension, 10.67% (27/253) had HIV infection, 8.70% (22/253) had diabetes, 3.95% (10/253) had liver cancer, 1.98% (5/253) had chronic hepatitis B, and 7.91% (20/253) were treatment-experienced patients. As for genotype distribution, 2.77% (7/253) had genotype 1, 12.65% (32/253) had genotype 2, 66.01% (167/253) had genotype 3, 16.60% (42/253) had genotype 6, and 1.98% (5/253) had unknown genotype. The patients had an overall SVR12 rate of 92.09%, with an SVR12 rate of 93.02% in the CLC group and 91.02% in the CHC group. The multivariate logistic regression analysis showed that age (odds ratio [OR]=1.086, 95% confidence interval [CI]: 1.007 — 1.170, P=0.032) and HCC (OR=9.178, 95%CI: 1.722 — 48.912, P=0.009) were independent influencing factors for sustained virologic response. Compared with baseline data, the CLC group had significant reductions in alanine aminotransferase (ALT) (χ2=107.103, P0.05), aspartate aminotransferase (AST) (χ2=90.602, P0.05), and LSM (χ2=42.235, P0.05) after 12 weeks of treatment, while the CHC group had significant reductions in total bilirubin (χ2=15.113, P0.05), ALT (χ2=202.237, P0.05), AST (χ2=161.193, P0.05), and LSM (χ2=37.606, P0.05). The incidence rate of serious adverse events was 1.58%, and none of the patients withdrew from drug therapy; the patients with such events were relieved after active symptomatic treatment. The incidence rate of all adverse events was 23.72%, among which fatigue (17.39%) and nausea (2.37%) were the most common adverse events, and these events often disappeared within 2 weeks or were gradually relieved after symptomatic treatment. ConclusionCoblopasvir hydrochloride capsules/sofosbuvir tablets with or without ribavirin tablets has good efficacy and safety in the treatment of chronic HCV infection.

Mycoplasmatota is a large class of special wall-less prokaryotic microorganisms,which is widely distributed in nature.Among them,Mycoplasma pneumoniae and other important pathogens are harmful to human health.The classification and naming history of Mycoplasmatota are very complex,which leaded to the fact that a species often has multiple homotypic and heterotypic synonyms.At the same time,due to the lack of a unified Chinese translation principle,one name has different translations.Moreover,most of Mycoplasmatota species lack of Chinese translated names and there is a situation of mixing Chinese and English.In 2018,based on whole genome analysis,the taxonomy of Mycoplasmatota underwent significant chan-ges.In order to standardize the Chinese translation of Mycoplasmatota names and end the confusion,and enable the researchers and clinical workers engaged in Mycoplasmatota prevention and treatment to track changes and use the names of Mycoplasma-tota,Beijing Friendship Hospital,Capital Medical University;National Institute for Communicable Disease Control,Chinese Centre for Disease Control and Prevention;Committee of Zoonoses Etiology,Chinese Society for Microbiology and Society of Biodiagnostic Technology,China Medical Biotechnology Association organized experts in this field to conduct literature research and expert discussions,and formed this consensus on the systematic Chinese translation principle and Chinese translation names for all existing levels in Mycoplasmatota.
