OBJECTIVE To provide reference for improving the rational use of antimicrobial drugs in primary township medical institutions. METHODS Based on the county prescription pre-review center， a team led by anti-infective clinical pharmacists constructed the management mode for the use of antimicrobial drugs in county-level medical communities with clinical pharmacists as the main team by finding out the main problems in the use of antimicrobial drugs in primary township medical institutions， providing feedback on the problems， organizing relevant training for the problems， improving the customization rules of the prescription pre-review software， implementing the automatic interception and pharmacist online prescription review and other measures. Data on the use of antimicrobial drugs were collected and compared in the 15 primary township medical institutions between January-June in 2022 （before the implementation of the mode） and January-June in 2023 （after the implementation of the mode）. RESULTS Compared with before the implementation of the mode， the utilization rate of antimicrobial drugs in outpatients of primary township medical institutions decreased from 24.97% before the implementation of the mode to 19.39% after the implementation of the mode； the utilization rate of antimicrobial injection in outpatients decreased from 66.10% to 46.80%； the utilization rate of intravenous drip of antimicrobial drugs in outpatients decreased from 52.33% to 40.35%； the rates of combined use of antimicrobial drugs in outpatients decreased from 12.70% to 8.19%； the reasonable rate of antimicrobial prescribing in outpatients increased from 55.28% to 73.93%. After the implementation of the mode， the proportion of antimicrobial prescriptions for each diagnosis was basically the same as before； the defined daily dose system （DDDs） and proportion of a few antimicrobial drugs changed compared with before according to the anatomical therapeutic chemical classification of drugs， among which DDDs of lincomycin， gentamicin and other drugs declined significantly； DDDs of antimicrobial drugs for each classification was basically the same as before according to AWaRe classification. CONCLUSIONS The management mode of the use of antimicrobial drugs led by anti-infective clinical pharmacists is constructed in the prescription pre-reviewing center of county-level medical communities， which can effectively improve the rational use of antimicrobial drugs in the primary township medical institutions.

Objective To evaluate the influence of the single and multiple intervertebral space radiofrequency ablation nucleoplasty on the sheep cervical spine stability.Methods Twenty healthy adult sheep were randomly divided into single intervertebral space operation group (A group )and multiple intervertebral space operation group ( B group ),each group was subdivided into postoperative 24 hours group ( A1,B1 group ) and post- operative 3 months group ( A2,B2 group),each group had five sheep.Radiofrequency ablation nucleoplasty on sheep C3/4 in the single intervertebral space operation group or C3/4,C4/5 in multiple intervertebral space operation group.Preoperative cervical vertebrae roentgenograms from all samples in neutral,lateral,hyperextension and hyperflexion positions were collected,and 5F pipe was used as the survey mark of ieonography.For the postoperative 24 hours group( A1,B1 group ),the roentgenograms were collected postoperatively 24 hours later,while for post- operative 3 months group (A2,B2 group),they were collected postoperatively 3 months later.The height of operative intervertebral space,horizontal and angular displacement of neighboring vertebral body were measured respectively.Results The roentgenograms showed no any obvious decrease in the height of intervertebral disc and no any increase in horizontal and angular displacement of neighboring vertebral body were observed in single intervertebral space operation group (A group) and multiple intervertebral space operation group (B group ).There was no significant difference between pre - operation and post - operation in them ( P ＞ 0.05 ).Conclusions The stability of the sheep cervical spine had not been affected by the single or multiple intervertebral space radiofrequency ablation nucleoplasty on the basis of X-ray results.The radiofrequency ablation nucleoplasty had no influences on the stability of sheep cervical vertebrae.

Objective To investigate the radioactivity levels of total α and total β in drinking water in nine districts of Chongqing City from 2019 to 2021, and to provide reference for the risk monitoring of drinking water in the metropolitan areas of Chongqing. Methods The total α and total β radioactivity levels in water samples were determined by the comparative measurement method and the thin source deposit method in GB/T5750.13-2006 ^“Standard Examination Methods for Drinking Water-Radiological Parameters^”. The monitoring results were assessed according to GB5749-2006 ^“Standards for Drinking Water Quality^” and the fourth edition of the WHO Guidelines for Drinking Water Quality. Results From 2019 to 2021, the total α activity concentration of the water samples measured in the nine districts of metropolitan Chongqing ranged from 0.002 to 0.039 Bq /L, and the total β activity concentration ranged from 0.015 to 0.190 Bq /L. There was no significant difference in the activity concentration (tα=0.545, Pα=0.591; tβ=-1.438, Pβ=0.163>0.05). From 2019 to 2021, the average value of total α radioactivity decreased year by year and its activity value was relatively low, indicating a low health risk. However, the average value of total β radioactivity increased year by year, which should be paid attention to. Conclusion The total α and total β radioactivity in water samples measured in the present study are lower than the standard recommended limits. The estimated annual average effective dose of radiation caused by drinking water is 0.005-0.010 mSv, which is lower than the limit of 0.1 mSv recommended by WHO, and this radioactivity level will not have an impact on the health of residents. However, the total β radioactivity level of the monitoring points in Banan and Shapingba is relatively high compared to other jurisdictions, and further tracking and monitoring should be carried out.

Objective To investigate the metabolite changes in systemic lupus erythematosus (SLE) patients with and without neuropsychiatric symptoms using magnetic resonance spectroscopy (MRS) and explore the associations between image findings and clinical variables. Methods Twenty-two SLE patients with neuropsychiatric symptoms (NPSLE), twenty-one SLE patients without neuropsychiatric symptoms (non-NPSLE) and twenty healthy controls (HCs) underwent routine MRI scan and multivoxel magnetic reson-ance spectroscopy (MVS). The absolute metabolite concentrations were measured bilaterally in the posterior cingulate gyrus (PCG), dorsal thalamus (DT), lentiform nucleus (LN) and posterior paratrigonal white matter (PWM) using LCModel and SAGE software. The relationships between metabolite con-centrations and cognitive function scores were analyzed by Spearman rank correlation. Single-factor Chi-square analysis and t-test were used for analysis. Results ① Compared to control subjects, NPSLE patients had significantly lower N-acetylaspartate (NAA) values in bilateral PCG and DT, with the mean differences of -1.504 [95% confidence interval ( CI) (-2.335, -0.672), P=0.001], -1.460 [95%CI (-2.349, -0.570), P=0.002], -1.259 [95%CI (-1.894, -0.625), P=0.000] and -1.022[95%CI (-1.688, -0.356), P=0.003] for RPCG, LPCG, RDT and LDT, respectively. The concentration of total creatinine were observed to decline in RPCG and RDT, with the mean differences of-1.094 [95%CI (-1.845, -0.342), P=0.003], -0.955 [95%CI (-1.630, -0.280), P=0.006], -1.259 [95%CI (-1.894,-0.625), P=0.006] respectively. Glutamine and glutamate-values decreased significantly in RDT [mean difference=-2.586, 95%CI (-4.139, -1.033), P=0.002]. ② Compared to non-NPSLE patients, NPSLE patients had a lower NAA level in LPCG [mean difference=-1.256, 95%CI (-2.146, -0.367), P=0.006]. Positive correlations between mini-mental state examination scores [RPCG: rs=0.312, P<0.05; LPCG: rs=0.355, P<0.01], Montreal cognitive assessment scores (RPCG: rs=0.362, P<0.01; LPCG: rs=0.285, P<0.05) and NAA values in bilateral PCG were detected. Conclusion Both NPSLE and non-NPSLE patients may have metabolite dysfun-ctions in different brain regions. The cognitive disorder in SLE patients may be interpreted by neuronic damage of PCG.

Methods Eighty patients with oral lichen planus were assigned to two groups. The experiment group was sublingually given 0.0015%of tacrolimus so-lution twice a day, and was orally given 100 mg of hydroxychloroquine sulphate tablets once a day. The control group was orally given 100 mg of hydroxychloroquine sulphate tablets once a day. The treatment was observed for 4 weeks, and the effective rate and incidence of adverse effects at the end of the treatment were evaluated. Results The effective rate of experiment group was 95.0%, and the control group was 35.0%. The short-term curative effect of hydroxychloro-quine sulphate combined with tacrolimus in the treatment of oral lichen planus was significantly better than that of hydroxychloroquine sulphate alone (χ2=31.65, P=0.00), but the incidence of adverse had not significantly different be-tween two groups. Conclusion The short-term curative effect of hydroxychloroquine sulphate combined with tacrolimus in the treatment of oral lichen planus is significantly better than that of hydroxychloroquine sulphate alone, which is safe and effective, and is worthy of clinical promotion and application.

Objective:To evaluate the clinical efficacy of modified Liqi-Hewei Decoction combined with conventional western medicine therapy in the treatment of Hp-positive chronic superficial gastritis (CSG). Methods:A total of 96 patients with Hp-positive CSG in the First People’s Hospital of Lianyungang and Changshu No.1 People’s Hospital who met the inclusion criteria between January 2017 and January 2019 were divided into two groups according to the random number table method, with 48 in each group. The control group was treated with conventional western medicine, and study group was additionally given modified Liqi-Hewei Decoction on the basis of control group. Both groups were treated for 8 weeks and followed up for 12 weeks. The TCM symptom score, gastric mucosa and pathological grading were scored before and after treatment. Levels of motilin, gastrin and somatostatin were detected by immunoturbidimetry, and levels of CD3 +, CD4 + and CD8 + were detected by automatic flow cytometry and the ratio of CD4 +/CD8 + was calculated. The Hp negative conversion rate was observed, the adverse reactions were recorded, the clinical efficacy was evaluated and the recurrence rate was statistically analyzed. Results:The Hp negative conversion rate was 89.6% (43/48) in study group and was 72.9% (35/48) in control group, where the difference was statistically significant ( χ2=4.376, P=0.036). The total effective rate was 95.8% (46/48) in study group and was 83.3% (40/48) in control group ( χ2=5.031, P=0.025). After treatment, the scores of epigastric pain, upper abdominal fullness, acid reflux, belching and poor appetite in the study group were significantly lower than those in control group ( t=8.919, 3.971, 7.949, 8.171, 9.865, all Ps<0.01). The scores of gastric mucosa and pathological grading were significantly lower than those in control group ( t=13.705, 15.495, all Ps<0.001). After treatment, the levels of gastrin [(126.15 ± 14.36) ng/L vs. (152.38 ± 17.51) ng/L, t=8.025], motilin [(93.59 ± 11.87) ng/L vs. (102.48 ± 14.68) ng/L, t=3.263] and somatostatin [(36.76 ± 8.97) ng/L vs. (40.84 ± 10.68) ng/L, t=2.027] in the study group were significantly lower than those in the control group ( P<0.01 or P<0.05). The levels of CD3 +, CD4 + and CD4 +/CD8 + were significantly higher than those in the control group ( t=6.883, 6.720, 4.306, all Ps<0.001). The recurrence rate was 4.3% (2/46) in the study group and was 17.5% (7/40) in the control group ( χ2=3.950, P=0.046). During treatment, the incidence rate of adverse reactions was 8.3% (4/48) in the study group and was 12.5% (6/48) in the control group ( χ2=0.446, P=0.504). Conclusion:Modified Liqi-Hewei Decoction combined with conventional western medicine therapy can effectively improve the levels of gastrointestinal hormones and clinical symptoms, enhance the immunity and Hp negative conversion rate, and reduce the recurrence rate of patients with Hp-positive CSG.
