Objective:To study the expression of MMP-9 and eosinophils in nasal polyps and its influence on the prognosis. Method:Study the expression of MMP-9 and EOS on the tissue of nasal polyps of patients who were cured or recurrent and normal nasal mucosa(NM) by immunohistochemisty and HE staining. Result:In the patients of recurrent group (Group B) , the expression of MMP-9 was much stronger than that of good prognosis group (Group A) and NM. The MMP-9 was stronger in the eosinophil nasal polyps than that of non-eosinophil groups. The percentage of EOS in Group A was 16.67% , while 62.50% in the Group B. Conclusion:The stronger expres-sion of MMP-9 on Group B and eosinophil group indicated that MMP-9 might affect the prognosis of nasal polyps through inducing the number of EOS in the mucosa. MMP-9 may be one of the risk factors for the relapse of nasal polyps.

Objective: To investigate the protective effects of caspase-1 inhibitor VX765 on gastric mucosa of mice with cold-restraint stress-induced acute gastric ulcer. Methods: Twenty-four specific pathogen free male C57BL/6J mice were divided into normal control group (NC), cold restrain group (CR), VX765 pre-treatment+ cold restrain group (VCR), and rabeprazole pre-treatment+ cold restrain group (RCR) according to the random number table, with 6 mice in each group. Mice in group NC were injected intraperitoneally with solution of 10 mL/kg dimethylsulfoxide (DMSO) and phosphate buffer solution (PBS). Mice in group CR were inflicted with acute gastric ulcer induced by cold-restraint stress 30 minutes after intraperitoneal injection of solution of DMSO and PBS. Mice in groups VCR and RCR were inflicted with acute gastric ulcer as above 30 minutes after intraperitoneal injection of solution of DMSO and PBS with dose of 12.5 μmol/kg containing 10 mg VX765 and 40 mg/kg containing 20 mg rabeprazole, respectively. Four hour after cold-restraint stress, serum content of tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6)was determined by enzyme-linked immunosorbent assay. Gross condition of gastric tissue was observed. Ulcer index was evaluated. Pathological change of gastric tissue was observed with HE staining. The relative expression of IL-1β, IL-18, and cleaved-caspase-1 in gastric tissue were detected by Western blotting. Mice in group NC were detected as above at the same time point. Data were processed with one-way analysis of variance and Bonferroni test. Results: The serum content of TNF-α and IL-6 and the relative expression of cleaved-caspase-1, IL-1β, and IL-18 in gastric tissue of mice in group NC were significantly lower than those in group CR (with P values below 0.01). The content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice in group VCR was significantly lower than that in group CR (with P values below 0.01). There were no statistically significant differences in content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice between groups RCR and CR (with P values above 0.05). The content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice in group VCR was significantly lower than that in group RCR (with P values below 0.01). Surface of gastric mucosa was smooth and morphology of mucosal cells was normal with clear structure of mice in group NC. Multiple hemorrhage of gastric mucosa, disorderly arrangement of mucosal cells, and large number of inflammatory cell infiltration around necrotic tissue were observed in mice of group CR. Decreased number of gastric mucosa bleeding, intact mucosal structure, and small amount of inflammatory cell infiltration around necrotic tissue were observed in mice of groups VCR and RCR. The ulcer indexes of mice in groups NC, CR, VCR, and RCR were 0, 18.7±1.1, 6.3±1.5, and 8.2±1.3, respectively. The ulcer index of mice in group NC was significantly lower than that in the other 3 groups (with P values below 0.05). The ulcer indexes of mice in groups VCR and RCR were close (P>0.05), which were significantly lower than ulcer index of mice in group CR (with P values below 0.05). Conclusions VX765 can effectively inhibit the activation of caspase-1, reduce production of inflammatory factor, and alleviate inflammatory response, which have protective effects on gastric mucosa of mice with cold-restraint stress-induced acute gastric ulcer.

Objective:To investigate the effects of preoperative pre-rehabilitation on early functional recovery after knee arthroplasty under the multidisciplinary collaboration mode of accelerated rehabilitation surgery.Methods:The clinical data of 51 patients who underwent total knee arthroplasty in the Department of Orthopedics, Jinjiang Hospital from September 2019 to December 2021 were retrospectively analyzed. These patients were divided into an observation group ( n = 24) and a control group ( n = 27). The observation group received pre-rehabilitation before knee replacement surgery, while the control group did not. After completing the admission procedures, patients in the observation group underwent rehabilitation evaluation in the rehabilitation clinic and received individualized rehabilitation training. The control group did not undergo preoperative pre-rehabilitation but underwent the same individualized rehabilitation training as the observation group. The rehabilitation specialist evaluated the patients' rehabilitation scores [hospital for special surgery knee (HSS) score, visual analog scale (VAS) score] at 2 and 5 days after surgery. The main outcome measures included the range of motion (ROM) of the patient's knee joint at 2 and 5 days after surgery, HSS score at 2 and 5 days after surgery, VAS score at 5 days after surgery, the number of days from surgery to discharge, the incidence of postoperative complications, and the rate of outpatient visits after surgery. Results:There was no significant difference in postoperative ROM of the knee joint between the observation and control groups at 2 days after surgery ( P > 0.05). However, there was a significant difference in score of ROM of the knee joint at 5 days after surgery between the two groups [(100.08 ± 7.75) points vs. (88.44 ± 16.09) points, t = 3.34, P = 0.002]. There was no significant difference in HSS score between the two groups at 2 days after surgery ( P > 0.05). However, there was a significant difference in HSS score between the two groups at 5 days after surgery [(62.84 ± 5.78) points vs. (57.09 ± 6.53) points, t = 3.31, P = 0.002]. There was a significant difference in VAS score (exercise) between the two groups at 5 days after surgery [(3.42 ± 1.02) points vs. (5.37 ± 1.15) points, t = -6.39, P < 0.001]. There was no significant difference in the number of days from surgery to discharge between the two groups ( P > 0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P > 0.05). However, there was a significant difference in the rate of outpatient visits between the two groups [7/17 vs. 1/26, χ2 = 4.45, P = 0.035]. Conclusion:Preoperative pre-rehabilitation in the accelerated rehabilitation surgery model under multidisciplinary collaboration can help improve the early function of patients undergoing total knee arthroplasty, reduce the pain of postoperative rehabilitation, improve the postoperative rehabilitation compliance, and ultimately enhance patient satisfaction with the surgery.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.

Near-infrared spectroscopy(NIRS) combined with band screening method and modeling algorithm can be used to achieve the rapid and non-destructive detection of the traditional Chinese medicine(TCM) production process. This paper focused on the ginkgo leaf macroporous resin purification process, which is the key technology of Yinshen Tongluo Capsules, in order to achieve the rapid determination of quercetin, kaempferol and isorhamnetin in effluent. The abnormal spectrum was eliminated by Mahalanobis distance algorithm, and the data set was divided by the sample set partitioning method based on joint X-Y distances(SPXY). The key information bands were selected by synergy interval partial least squares(siPLS); based on that, competitive adaptive reweighted sampling(CARS), successive projections algorithm(SPA) and Monte Carlo uninformative variable(MC-UVE) were used to select wavelengths to obtain less but more critical variable data. With selected key variables as input, the quantitative analysis model was established by genetic algorithm joint extreme learning machine(GA-ELM) algorithm. The performance of the model was compared with that of partial least squares regression(PLSR). The results showed that the combination with siPLS-CARS-GA-ELM could achieve the optimal model performance with the minimum number of variables. The calibration set correlation coefficient R_c and the validation set correlation coefficient R_p of quercetin, kaempferol and isorhamnetin were all above 0.98. The root mean square error of calibration(RMSEC), the root mean square error of prediction(RMSEP) and the relative standard errors of prediction(RSEP) were 0.030 0, 0.029 2 and 8.88%, 0.041 4, 0.034 8 and 8.46%, 0.029 3, 0.027 1 and 10.10%, respectively. Compared with the PLSR me-thod, the performance of the GA-ELM model was greatly improved, which proved that NIRS combined with GA-ELM method has a great potential for rapid determination of effective components of TCM.
