Objective To observe the effects of modified Jianpi Yishen Decoction on urinary osteopontin (OPN) in calcium oxalate nephrolithiasis patients after percutaneous nephrolithotomy (PCNL) or ureteroscope lithotomy (URL);To clarify the mechanism of modified Jianpi Yishen Decoction on the prevention of calcium oxalate kidney stones. Methods Totally 116 calcium oxalate nephrolithiasis patients were randomly divided into trial group (62 cases) and control group (54 cases). The trial group took modified Jianpi Yishen Decoction every other day, while the control group took potassium sodium hydrogen citrate granules three times a day. The concentrations of OPN, urinary calcium and urinary oxalic acid of the patients in the two groups were observed before treatment and 2 weeks and 4 weeks of treatment. Results The concentration of urinary OPN of 2 weeks and 4 weeks of the treatment in the trial group was significantly increased compared with before treatment (P<0.05), and the difference was statistically significant compared with the control group (P<0.05). The concentration of urinary OPN in the control group had no significant change after treatment (P>0.05). The differences in the concentrations of urinary calcium and urinary oxalic acid of the two groups between before and after treatment were not significant (P>0.05). Conclusion Modified Jianpi Yishen Decoction can effectively restrain the formation of the calcium oxalate stones by increasing the level of urinary OPN, which demonstrates effective prevention in the calcium oxalate nephrolithiasis patients after PCNL or URL.

Objective To observe the dynamic expressions of kielin/chordin-like protein (kcp) in mouse model of hepatic fibrosis and the effects of bone morphogenetic protein-7 (BMP-7)intervention on the expressions,and to explore a new target for treatment of fibrosis.Methods A total of 50 healthy male ICR mice were divided into three groups:control group(n=10) ; model group (n=30) and BMP-7 treatment group (n=10).The model group was further divided into three subgroups according to different time points:subgroups of 4,8 and 12 weeks with 10 mice in each subgroup.The mouse model of hepatic fibrosis was established by hypodermic injection of carbon tetrachloride(CCl4 ).The mice in BMP-7 treatment group began to receive human recombmant BMP- 7via intraperitoneal injection after 8 weeks of the first administration of CC14 and lasted for 4 weeks.The serum levels of alanine aminotransferase (ALT),aspartate transaminase (AST) and albumin (Alb) were detected.The pathological changes of liver were observed under optical microscope after HE and Masson staining.The dynamic expressions of kcp mRNA and protein of each group were detected by reverse transcription-polymerase chain reaction,immunohistochemistry and Western blot.The comparison of means among groups was done by univariate ANOVA.Results In model group,ALT and AST levels increased,while Alb level gradually decreased,and peaked at week 12.BMP-7treatment could reduce the changes,and there were significant differences among groups (F=23.501,34.600 and 16.244,respectively; all P＜0.05).In normal control group,the expressions of kcp mRNA and protein were low,while those in model group were gradually increased.BMP-7 treatment could achieve remission and the changes were all significantly different among groups (F=30.362 and 10.727,respectively; P＜0.01 or 0.05).The expression of kcp mRNA was positively correlated with levels of transforming growth factor (TGF)-β1 mRNA and BMP-7 mRNA (r=0.760 and 0.769,respectively; both P＜0.05).Conclusions BMP 7 can improve the hepatic fibrosis in mice.kcp may play an important role in the occurrence and development of liver fibrosis which is a potential therapeutic target for hepatic fibrosis.

At present,specific targeted treatment of vitiligo is still lacking,and there are many limitations of current therapies,such as slow repigmentation process,long duration of treatment and frequent recurrence.As a therapeutic strategy for rapidly improving the appearance of patients,camouflage therapy has a unique advantage in the treatment of various skin diseases.Several studies in China and other countries have shown that the correct use of cosmetic camouflage can effectively improve the appearance and quality of life of patients with vitiligo.This review summarizes the knowledge about various camouflage therapies and related clinical researches on the relationship between camouflage therapies and quality of life of patients with vitiligo,and elaborates application prospects of camouflage therapies in the treatment of vitiligo.

Objective To investigate the expression of miR-124 in glioblastoma (GBM) cell lines LN229 and LN229R,as well as the regulatory mechanism of miR-124 on radiosensitivity of LN229R cells.Methods miR-124 mimic (miR-124) and negative control (miR-NC),STAT3 overexpression plasmid (STAT3) and pcDNA3.1 vector (pcDNA) were transfected or co-transfected into radioresistant glioma cells LN229R.qRT-PCR was employed to analyze the expression of miR-124 in LN229 and LN229R cells.The survival rate and sensitivity-related parameters of LN229R cells at different doses were analyzed by cloning formation assay.Cell apoptosis of LN229R was evaluated by flow cytometry.Targeting gene of miR-124 was predicted using Targetscan software and verified by the double-luciferase reporter assay.Western blot assay was performed to detect STAT3 protein expression.Results The expression of miR-124 in LN229R cells (0.32 ± 0.03) was significantly lower than that in LN229 cells (1.02 ± 0.09) (t =12.780,P＜0.05).Transfection of miR-124 mimics promoted the expression of miR-124 in LN229R cells (4.02±0.39) compared with miR-NC group (0.95±0.06) (t=13.476,P＜0.05).After 8 Gy irradiation,the survival rate of LN229R cells transfected with miR-124 mimics (0.003 ± 0.000 4) was significantly lower than that in miR-NC group (0.033±0.005 0) (t=5.655,P＜0.05),and the apoptosis rate (22.34±2.42) ％ was significantly higher than that in miR-NC group (4.69 ± 0.51) ％ (t =12.361,P＜0.05).STAT3 was identified to be a target gene of miR-124.Exogenous restoration of STAT3 reversed the inhibitory effect of miR-124 on LN229R cell survival.Conclusion miR-124 increases the radiosensitivity of LN229R cells by targeting STAT3.

Objective:To study the clinical results of robot-assisted laparoscopic resection for choledochal cysts.Methods:From October 2020 to June 2022, clinical data on 20 patients who underwent choledochal da Vinci robot-assisted laparoscopic choledochal cyst resection at Fujian Provincial Hospital were retrospectively analyzed. Forty-two children with choledochal cysts were included in this study. There were 16 males and 26 females, aged 25 (range 15.0 to 45.0) months. The operations were carried out by the same team of surgeons. These patients were divided into two groups based on the surgical methods: children who underwent da Vinci robot-assisted laparoscopic surgery were in the robotic group ( n=20) and children who underwent single-port (transumbilical) laparoscopic surgery were in the laparoscopic group ( n=22). The general clinical data, operation time, intraoperative blood loss, fasting time, hospital stay, total medical costs and complications were collectd and analysed. Follow-up was performed in outpatient visits. Results:Both the 2 groups underwent surgery successfully, and no patient was converted to laparotomy. When compared with the laparoscopic group, intraoperative blood loss [(10.65±3.75) vs. (14.86±3.75) ml], indwelling time of abdominal drainage tube [(5.45±2.21) vs. (7.05±1.94) d] and fasting time [(4.00±1.49) vs. (6.05±1.43) d] in the robotic group were significantly less, while the operation time [394(299, 422) vs. 351(269, 380) min] and hospitalization cost [(79 200±4 000) vs. (31 100±3 000) yuan] were significantly increased (all P<0.05). The differences in postoperative complication rates and pain score between the two groups showed no significant differences (all P>0.05). On follow-up, no patients developed complications such as cholangitis, jaundice, intestinal obstruction and cholangiocarcinoma, except for one patient in the laparoscopic group who developed cholangitis after surgery. Conclusion:Robot-assisted laparoscopic choledochal cystectomy was effective and safe in treatment of children with choledochal cysts.

Objective:To explore the early clinical efficacy of ultrasound visualized platelet-rich plasma (PRP) in the treatment of lower back myofascial pain syndrome (MPS) after sports injury.Methods:A prospective cohort study was conducted to analyze the clinical data of 32 patients with lower back MPS after sports injury, who were admitted to West China Hospital of Sichuan University from January 2023 to March 2023. Ultrasound-guided PRP injection into the erector spinalis or quadratus psoas muscles was used for treatment. Before treatment, at 24 hours, 2 weeks, and 4 weeks after treatment, pain and function were evaluated using visual analogue scale (VAS), McGill pain questionnaire (McGill), Roland Morris dysfunction questionnaire (RMDQ), and Oswestry dysfunction index (ODI). Before treatment and 4 weeks after treatment, the quality of life was evaluated using the short-form 36 item health survey questionnaire (SF-36). The adverse reactions were observed during treatment and follow-up.Results:A total of 32 patients with lower back MPS after sports injury were enrolled, including 10 males and 22 females; aged 12-68 years [(47.3±16.3)years]. All the patients were followed up for 4 weeks. Before and at 24 hours, 2 weeks, and 4 weeks after treatment, the VAS was 5.0(4.0, 6.0)points, 3.5(3.0, 4.8)points, 2.0(2.0, 3.0)points, and 2.0(1.3, 3.0)points, respectively; the McGill score was 9.0(7.0, 11.0)points, 7.0(5.0, 9.0)points, 4.0(3.0, 5.0)points, and 3.0(3.0, 5.0)points, respectively; the RMDQ score was 8.0(5.3, 10.8)points, 5.5(3.0, 8.0)points, 4.0(3.0, 5.8)points, and 3.0(2.0, 4.8)points, respectively; the ODI was 22.0(14.5, 30.0), 20.0(14.5, 25.5), 9.0(6.0, 16.0), and 8.0(4.5, 14.0), respectively. Compared with the values before treatment, the VAS, McGill score, and RMDQ score were significantly decreased at 24 hours, 2 weeks, and 4 weeks after treatment (all P<0.05); the ODI had no significant difference at 24 hours after treatment ( P>0.05), but it was significantly decreased at 2 and 4 weeks after treatment (all P<0.05). Compared with the values at 24 hours after treatment, the VAS, McGill score, RMDQ score and ODI further decreased at 2 weeks after treatment (all P<0.05). Compared with the values at 2 weeks after treatment, there was no significant difference in the VAS, McGill score, RMDQ score, or ODI at 4 weeks after treatment (all P>0.05). In the SF-36, the scores of physiological function [77.5(60.0, 93.8)points], physiological role [50.0(0.0, 100.0)points], body pain [64.0(44.5, 74.0)points], vitality [75.0(65.0, 78.8)points], social function [87.5(75.0, 100.0)points], emotional role [66.7(33.3, 100.0)points] and mental health [72.0(68.0, 83.0)points] before treatment were increased to 90.0(80.0, 98.8)points, 100.0(56.3, 100.0)points, 84.0(74.0, 84.0)points, 75.0(70.0, 80.0)points, 100.0(87.5, 112.5)points, 100.0(66.7, 100.0)points, and 76.0(68.0, 84.0)points after 4 weeks of treatment, respectively ( P<0.05 or 0.01). However, there was no significant difference in the general health status or health changes before and after treatment (all P>0.05). During treatment and follow-up, no adverse reactions such as redness, swelling, pain, or subcutaneous bleeding were observed. Conclusion:Ultrasound-guided PRP treatment can improve the early pain, lumbar mobility and quality of life of patients with lower back MPS after sports injury, with no presence of adverse reactions.

Objective:To asscentain the 131I activity concentration in 131I treatment workplaces and to explore the method of estimating the internal dose to workers by air sampling and to analyze its influencing factors. Methods:Air sampling method was used to collect aerosols containing radioactivity in 10 randomly selected workplaces in Zhengzhou where 131I therapy was performed. Aactivity concentration of 131I in treatment workplace was measured for gamma emitters by gamma-ray spectrometry. The internal dose due to 131I inhalation was estimated based on measurement result and field investigation result. Results:The activity concentration of 131I in air samples from 19 subpacking rooms ranged from 0.087 to 570 Bq/m 3, with an average of (51.04 ± 128.58) Bq/m 3. Those from 11 wards ranged from 0.162 to 54.6 Bq/m 3, with an average of (7.97 ± 15.89) Bq/m 3. In terms of the work hours recommended by the national standard GBZ 129-2016 Specifications for individual monitoring of occupational internal exposure, the estimated annual effective dose to radiation workers due to the inhalation of 131I ranges from 0.002 to 10 mSv, with an average of (0.61 ± 1.80) mSv, below the dose limit specified in the national standards. Conclusions:The samples with high 131I activity concentration in nuclear medicine workplaces of 10 medical institutions selected in Zhengzhou are mostly distributed in tertiary class hospitals operating large amount of radionuclide with large numbers of thyroid cancer patients adimitted. The result ing internal dose to radiation workers cannot be ignored. Estimating the internal dose based on the measurement result of air samples has a large uncertainty.However, air sampling method can promptly detect radioactive contamination in case of abnormal events or accidents, providing early warning for workers to carry out dose measurement from external exposure and internal exposure assessment.
