OBJECTIVE: To observe the effects of point-moxibustion with Zhuang medicinal thread on differentially expressed genes (DEGs) in the dorsal root ganglion (DRG), tissue morphology, and the expression of Fc epsilon RI (FcεRI) pathway proteins spleen tyrosine kinase (Syk) and membrane spanning 4-domain A2 (MS4A2) in rat model of postherpetic neuralgia (PHN), and to explore the potential mechanism by which this therapy alleviates pain sensitization. METHODS: Thirty-nine male Sprague-Dawley (SD) rats were randomly divided into a control group, a model group, and a moxibustion group, with 13 rats in each group. The PHN model was established in the model and moxibustion groups by intraperitoneal injection of resiniferatoxin. In the moxibustion group, bilateral L₄-L₆ "Jiaji" (EX-B2) points were treated with point-moxibustion with Zhuang medicinal thread from day 7 post-modeling, with two cones per acupoint per session, every other day for a total of 10 sessions. Mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured at 1 day before modeling and on days 1, 4, 7, 13, 19, and 25 after modeling. After intervention, HE staining was used to observe DRG morphology. RNA sequencing was performed to analyze DEGs in DRG and conduct bioinformatics analysis. The expression of Syk and MS4A2 mRNA and proteins in the FcεRI pathway in DRG was detected by quantitative PCR and Western blot. RESULTS: Compared with the control group, the model group exhibited decreased MWT (P<0.05) and increased TWL (P<0.05); histopathological analysis revealed neuronal atrophy, nuclear displacement, and intracellular vacuoles, with a slightly loose arrangement; the RNA-Seq identified 3,207 DEGs (1,997 upregulated and 1,210 downregulated); the mRNA and protein expression levels of Syk and MS4A2 were significantly increased (P<0.01). Compared with the model group, the moxibustion group showed increased MWT (P<0.05) and decreased TWL (P<0.05), with relatively normal neuronal morphology; the RNA-Seq identified 426 DEGs (250 upregulated and 176 downregulated); the mRNA and protein expression levels of Syk and MS4A2 were significantly decreased (P<0.05). Venn diagram analysis identified 156 DEGs that showed a reversal in expression trends after treatment, including Syk and MS4A2, which are associated with pain sensitization. KEGG pathway analysis indicated that these DEGs were primarily enriched in the FcεRI pathway. CONCLUSION Point-moxibustion with Zhuang medicinal thread could alleviate pain sensitization in PHN rats, possibly by inhibiting the FcεRI signaling pathway and downregulating the expression of Syk and MS4A2.

ObjectiveTo evaluate the effect and safety of Jiuxin Pill （救心丸） on exercise tolerance and quality of life in patients with stable angina pectoris （SAP）. MethodsA randomised， double-blind， placebo-controlled， multicentre study design was used to enroll 170 patients of SAP from nine centres， which were divided into 85 patients each in the trial group and control group with 1∶1 ratio. Both groups maintained the original western medicine treatment plan， and added Jiuxin Pill or placebo respectively， 2 pills （0.05 g） each time twicely for 28 days. The main outcomes were total exercise time （TED） in the exercise treadmill test and Seattle Angina Questionnaire （SAQ） scores including physical limitation （PL）， angina stability （AS）， angina frequency （AF）， treatment satisfaction （TS）， and disease perception （DP）. The secondary outcomes were exercise treadmill test indicators including heart rate recovery in 1 min （HRR1）， metabolic equivalents （METs）， maximum magnitude of ST-segment depression， and the Borg rating of perceived exertion scale， the average number of angina attacks per week， withdrawal and reduction rate of nitroglycerin， traditional Chinese medicine syndrome scores， incidence of major adverse cardiovascular events. Safety indicators were evaluated and the occurrence of adverse events during the trial was recorded. Data was collected before treatment， day 28±2 in treatment period， and follow-up at day 56 which is 28±2 days after treatment period finished. ResultsEighty-four and eighty-five patients respectively from trial group and control group were included to the full analysis set （FAS） and safety analysis set （SS）. Compared with the group before treatment and with the control group after treatment， the trial group had higher TED， HRR1， and METs， and lower maximum magnitude of ST-segment depression and Borg rating of perceived exertion scores after treatment （P＜0.01）. Compared with the group before treatment and with the control group after treatment and at follow-up， the total SAQ score and scores of AS， AF， TS and DP of the trial group after treatment and at follow-up elevated， while the average number of angina attacks per week and traditional Chinese medicine syndrome scores reduced （P＜0.01）. There was no statistically significant difference in the withdrawal and reduction rate of nitroglycerin between groups （P＞0.05）. Major adverse cardiovascular events occurred in 1 case （1/84， 1.19%） in the trial group and 1 case （1/85， 1.18%） in the control group， and the difference between groups was not statistically significant （P＞0.05）. A total of 3 cases of adverse events occurred in the trial group （3/84， 3.57%）， and a total of 6 cases of adverse events occurred in the control group （6/85， 7.06%）， and there was no statistically significant difference in the incidence of adverse events between groups （P＞0.05）. ConclusionIn the treatment of SAP， Jiuxin Pill combined with conventional western medicine can further enhance exercise tolerance， improve quality of life， and demonstrate great safety.

Objective:To evaluate the performance of key performance indicator (KPI) lean teaching management system in clinical medical laboratory.Methods:Combining lean teaching management in universities with KPI system of enterprises, an innovative KPI lean teaching management system was developed and applied in Clinical Medical Laboratory of Guangdong Provincial People′s Hospital (GDPH). A total of 106 teachers, who had worked from January 2021 to December 2022 in GDPH, joined this study. Teachers were divided into 8 professional groups. Firstly, we quantified the teaching workload by class hours, evaluated the teaching outcomes base on national, provincial, school, and college levels to assign different teaching points, and linked the teaching KPI scores to the evaluation, salary, and professional title of teachers. Then, we analyzed the overall teaching points and teaching points for each professional group (2021-2022). Finally, we asked teaching managers, teachers, and colleagues to evaluate the KPI lean teaching management system and compared the effects before and after the implementation of this system.Results:Compared with 2021, the teaching scores of 106 teachers increased significantly from 1.0 (0.2, 2.7) to 3.8 (2.3, 6.0) in 2022 ( Z=8.1, P<0.01). The teaching scores of clinical molecules, clinical coagulation, clinical immunology, clinical microbiology, Huifu laboratory, and clinical biochemistry group were significantly higher in 2022 than the scores they got in 2021 (all P<0.05). Compared with 2021, there were 3 new set up of educational reform projects, 2 submitted teaching articles, 3 new competition awards, 7 outstanding teachers, and 5 outstanding students in 2022. After application of KPI lean teaching management, the evaluation scores of teaching work by teaching managers, teachers, and colleagues are all significantly improved ( P<0.05). Conclusion:KPI lean teaching management system could effectively enhance teachers′ work initiative, improve teaching efficiency and outcome, and promote the teaching quality. Therefore, based on the performance of KPI lean teaching management system in our study, it is possible to realize its potential in terms of lean management in clinical medical laboratory.

Objective:To construct a prognostic nomogram based on epithelial-stromal interaction protein 1(EPSTI1)and predict the pro-gnosis of clear cell renal cell carcinoma(ccRCC).Methods:A retrospective analysis was performed from January 2012 to December 2015 at The First Affiliated Hospital of Fujian Medical University,on 221 patients with ccRCC who underwent surgical treatment in our center and 533 patients with ccRCC in The Cancer Genome Atlas(TCGA)database.Immunohistochemical(IHC)staining was performed on adjacent nor-mal and cancerous tissues to analyze the expression level of EPSTI1 and its correlation with clinicopathological characteristics.Kaplan-Meier survival analysis was performed for the overall survival(OS)and disease-free survival(DFS)of patients with high and low EPSTI1 expression levels.Univariate and multivariate Cox proportional hazards models were used to analyze the prognostic factors for OS,and a nomogram model was constructed and verified.Results:The IHC scores and mRNA expression levels of EPSTI1 were significantly higher in ccRCC tissues than in normal tissues(all P<0.001).EPSTI1 was expressed at higher levels in cancer tissues at higher T stages(P=0.036,P=0.006).The EPSTI1 protein expression level was related to the maximum tumor diameter and TNM stage(P=0.002,P=0.032,respectively).The OS and DFS were higher in the low-EPSTI1-expression group than the high-EPSTI1-expression group(P=0.046,P=0.003,P=0.001).Univariate and multivariate Cox regression analyses showed that a high EPSTI1 protein expression level,WHO/ISUP grade,and AJCC/TNM stage were independent risk factors for poor prognosis(P=0.009,P=0.039,P<0.001).The prognostic nomogram model constructed based on the above variables was su-perior to the AJCC/TNM stage in predicting the 5-year OS,and the calibration curve showed that the predicted value of the model was con-sistent with the actual value.Conclusions:The nomographic model based on EPSTI1,AJCC/TNM staging and WHO/ISUP staging has a strong predictive ability for the prognosis of renal clear cell carcinoma.

Background::Psoriasis is a chronic systemic inflammatory disease, and hyperuricemia is a common comorbidity in patients with psoriasis. However, there are limited reports on the relationship between serum uric acid levels and biological treatment efficacy. The purposes of this study were to compare the differences in serum uric acid levels between patients with psoriasis and healthy controls and analyze the risk of hyperuricemia.Methods::A total of 196 patients with psoriasis and 191 age- and sex-matched healthy controls were enrolled in this retrospective cohort study. One hundred and twenty-seven patients with severe psoriasis were treated with biologics. Sixty-eight patients received adalimumab, and 59 patients received secukinumab. Serum uric acid levels were measured at baseline, week 24, and week 48 of treatment.Results::Patients with psoriasis had higher serum uric acid levels than healthy controls (6.4 ± 1.7 mg/dL vs. 5.7 ± 1.5 mg/dL, P < 0.001). Hyperuricemia was found in 33.7% (66/196) of patients with psoriasis, which was significantly higher than that in healthy controls (13.1% [25/191], P < 0.001). Serum uric acid levels and hyperuricemia were not related to the severity of psoriasis ( P > 0.05). No significant changes in serum uric acid levels and hyperuricemia were observed following adalimumab treatment ( P > 0.05). The serum uric acid level in patients treated with secukinumab was 6.7 ± 1.6 mg/dL at week 24, which was not statistically different from that at baseline (6.6 ± 1.4 mg/dL, P = 0.885). Serum uric acid levels were significantly decreased at week 48 (6.3 ± 1.5 mg/dL vs. 6.6 ± 1.4 mg/dL, P = 0.007) in patients treated with secukinumab. Secukinumab had no significant effect on hyperuricemia either ( P > 0.05). Conclusions::The serum uric acid levels and prevalence of hyperuricemia in patients with psoriasis were significantly higher than those in healthy controls. Secukinumab treatment for 48 weeks successfully decreased serum uric acid levels in patients with psoriasis, whereas adalimumab had no significant effect on serum uric acid levels.

OBJECTIVE To provide reference for improving the professional identity of clinical pharmacists and the quality of pharmaceutical care ，and promoting the effects of clinical pharmaceutical intervention. METHODS A questionnaire survey was conducted among clinical pharmacists in secondary and tertiary hospitals in 31 provinces（autonomous regions and municipalities ） in 2019 by stratified semi-random sampling. Through descriptive analysis of survey data ，their job satisfaction status was evaluated ； χ 2 test and Logistic regression analysis were used to analyze the influential factors of job satisfaction ；the robustness test of study results by propensity score matching method and replacement regression model ，and grouping Logistic regression of samples from hospital on different levels. Targeted improvement measures were put forward according to the results of survey . RESULTS There was statistical significance in the difference of job satisfaction among pharmacists of different professional titles （P＜0.05）. Results of Logistic regression showed that whether to participate in standardized training ，whether to obtain communication and support from patients ，whether the pharmaceutical management rules and regulations were sound ，whether to set up economic compensation means such as pharmaceutical service fee ，whether to work overload ，and whether to smoothly perform pharmaceutical care duties were significant influential factors for job satisfaction of clinical pharmacists （P＜0.05）. These results showed good robustness as tested by propensity score matching method and replacement regression model. Heterogeneity analysis results showed that the job satisfaction of clinical pharmacists in tertiary hospitals was more significantly affected by economic compensation ，while clinical pharmacists in secondary hospitals were more concerned about training opportunities and workload conditions （P＜0.05）. CONCLUSIONS The job satisfaction level of Chinese clinical pharmacists remains to be improved. Accordingly ，it is compulsory to continue the promotion of standardized training courses ，consummate the pharmaceutical management system ，and fair remuneration structure in order to improve the job satisfaction of clinical pharmacists and build a high-level clinical pharmacist team.

Background The pollution of agricultural products and the health risks caused by metals have become a hot spot of social concern. As China's main economic agricultural products, peppers are essential for health risk assessment. Objective By exploring the enrichment of common metals in different varieties of peppers in major growing areas of China, a bioavailability-based approach is used to assess dietary health risks of common metals in groups with different characteristics. Methods Through random sampling method, dried pepper samples from major pepper growing areas of China were purchased from the market, and were divided into Hippophae, Capsicum annuum, Magnoliopsida, Capsicum frutescens var, and Capsicum by morphological taxonomy, and a total of 667 batches of peppers were collected. Six common metals arsenic (As), cadmium (Cd), lead (Pb), nickel (Ni), copper (Cu), and zinc (Zn) were evaluated; physiologically based extraction test was designed to estimate the bioavailability of the metals in peppers and their associated dietary health risks were assessed. Results The concentrations of metals Cd and Ni in pepper exceeded the limits of China, and the disqualification rates were 6.1% and 22.7% respectively. The other metals were within the safe range; there were differences in the concentrations of As, Cd, Pb, Cu, and Zn among different pepper varieties (P<0.05). The order of bioavailability of the six metals in pepper from high to low was As (57.9%)>Cd (43.07%)>Zn (42.74%)>Pb (38.04%)>Ni (31.97%)>Cu (31.4%). Based on bioavailability, when the metal concentration in pepper was at the median level, the order of hazard quotient of metals in pepper was Cu>Cd>As>Ni>Zn>Pb, and at the 90th quantile level, the order was Cd>As>Cu>Ni>Zn>Pb; the hazard quotient of single metal element and the total target hazard quotient of combined metal elements were both less than 1, and these indicators of adults were higher than those of children. Conclusion In the collected pepper samples, the non-carcinogenic health risks of single metal elements and multiple metal elements are in the safe range. Based on gastrointestinal bioavailability, the dietary health risk of pepper is further reduced.

In 2019, the rate of primary tooth caries rate among 1 598 preschool children in Shinan District and Shibei District of Qingdao was 59.4%. The multivariate logistic regression model showed that compared with children ≤ 2 years old with history of iron deficiency anemia (IDA), suffering IDA, breastfeeding to 2 years old and no tooth melanin, children ≤ 2 years old without history of IDA, not suffering IDA, breastfeeding to less than 2 years old and heavy tooth melanin had a lower risk of primary tooth caries, with OR ( 95%CI) values about 0.328 (0.197-0.549), 0.354 (0.208-0.603), 0.636 (0.437-0.926) and 0.301 (0.143-0.635), respectively.

Objective:To propose a monosegment thoracic and lumbar fracture dislocation (mTLFD) classification, and to evaluate its reliability and clinical application.Methods:All of 298 cases of thoracic and lumbar fracture dislocation who received surgical management in our hospital from January 2014 to December 2019 were retrospectively analyzed. 123 cases were included in the study according to inclusion and exclusion criteria. mTLFD classification was proposed based on the imaging characteristics: type I (intervertebral disc injury mainly) and type II (vertebral burst fracture mainly). The type II was classified based on distribution of injury segment: type IIa (T 11 and above) and Ttype IIb (below T 11). Six spinal surgeons (3 residents, 3 associate chief physicians) were selected to classify the 123 cases according to preoperative imaging data, and to perform reliability test of each type. The repeatability and reliability of the classification were evaluated by ICC index. Different management strategies were performedf or each type: type I was managed with posterior decompression interbody fusion and internal fixation; type IIa underwent posterior decompression and fixation, subtotal vertebral resection and fusion was performed if bony compromise was still present through intra-operative exploration. Type IIb underwent posterior decompression, posterolateral fusion and internal fixation on the first stage, while anterior subtotal vertebral resection and reconstruction was performed on the second stage if the bony compromise was still present based on post-operative CT examination. The American Spinal Injury Association (ASIA) grading of all patients was recorded, and the visual analogue scale (VAS), Oswetry disability Iindex (ODI) and local Cobb angle of each type was compared between pre-operation and final follow-up. Results:The average follow-up time of all patients was 10.4±1.8 months. The average repeatability and reliability ICC index of mTLFD of 3 residents and 3 deputy chief physicians were 0.926 and 0.964, respectively, and 0.746 and 0.907, respectively. The reliability ICC index of type I, type IIa and type IIb was 0.918, 0.947 and 0.962, respectively, and the repeatability ICC index was 0.930, 0.940 and 0.966, respectively. The neurological function recovery was obtained in 56 patients. The preoperative VAS of type I, type IIa and type IIb were 8.5±1.0, 8.4±1.0 and 8.3±0.9, and 2.0±1.1, 1.8±1.0 and 1.8±0.9 at the final follow-up (all P<0.001). The ODI of type I, type IIa and type IIb were 97.0%±2.1%, 97.1%±1.9% and 97.3%±2.1% before surgery, and 29.5%±6.8%, 27.0%±6.0% and 29.0%±6.7% at the final follow-up (all P<0.001). The local Cobb angles of type I, type IIa and type IIb were 20.9°±7.1°, 29.0°±9.1° and 26.4°±6.9° before surgery, and 12.5°±5.4°, 18.0°±9.1° and 13.1°±5.1° at the final follow-up (all P<0.001). Conclusion:The mTLFD classification proposed in this study has strong repeatability and reliability, and management strategy of each type have achieved satisfactory clinical efficacy, indicating that the classification has certain significance for management of thoracic and lumbar spine fracture dislocation.
