Stroke flaccid paralysis is stroke patients with abnormal physical movement function and muscle tone decline as the main performance and is a kind of common pathological state after apoplectic stroke. The longer the flaccid paralysis is, the worse the prognosis. The theory of TCM holds that stroke is mainly due to "deficiency, wind, fire, phlegm, stasis, qi", and when the pathogenic factor accumulate and block the meridians, which would cause blood stagnation, muscle and tendon damage and flaccidity, resulting in stroke paralysis. Therefore, it is necessary to set up the "Tongjing Roujin" (stimulating the muscle and nourishing the tendon) as its main treatment. Fire-needling has the effect of stimulating muscle, warming yang, nourishing tendon, and relieving pain in the treatment of stroke flaccid paralysis. It can warm yang and dissipate cold, replenish and nourish meridian qi, release muscle nodules, promote the circulation of qi and blood, and nourish all limbs and bones. Fire-needling therapy can promote the recovery of neural pathway, strengthen local metabolism, improve local muscle tension, and thus restore limb function. The high-quality clinical research, acupoint selection rules, and standardized operating techniques of fire-needling treatment for stroke flaccid paralysis need to be further deepened.

Objective:To evaluate the role of NOD-like receptor protein 3 (NLRP3) inflammasomes in curcumin-induced reduction of sevoflurane-induced postoperative cognitive dysfunction in rats.Methods:Forty SPF healthy male Sprague-Dawley rats, aged 17-18 months, with body mass index of 580-600 g, were divided into 4 groups ( n=10 each) by a random number table method: control group (C group), postoperative cognitive dysfunction group (P group), curcumin group (CU group), and curcumin+ NLRP3 inflammasome activator group (CN group). The rat model of postoperative cognitive dysfunction was prepared by inhaling 1.5% sevoflurane to explore the abdominal cavity. Curcumin suspension 300 mg/kg was given by intragastric administration in CU group and CN group, and the rats received intragastric administration of nidrisin sodium 5 mg/kg simultaneously in CN group, once a day for 6 consecutive days. Rats received the equal volume of normal saline instead in C group and P group. The frequency of crossing the original platform and time spent in the target quadrant were measured by the Morris water maze test. The histopathological changes of hippocampus were observed by HE staining, neuronal apoptosis was detected by TUNEL staining, and the expression of NLRP3, Bcl-2 and Bax was detected by Western blot. Results:Compared with C group, the frequency of crossing the original platform was significantly reduced, the time spent in the target quadrant was shortened, the apoptosis rate of neurons was increased, and the expression of NLRP3 and Bax was up-regulated, and the expression of Bcl-2 was down-regulated in P group ( P<0.05). Compared with P group, the frequency of crossing the original platform was significantly increased, the time spent in the target quadrant was prolonged, the apoptosis rate of neurons was decreased, and the expression of NLRP3 and Bax was down-regulated, and the expression of Bcl-2 was up-regulated in CU group ( P<0.05). Compared with CU group, the frequency of crossing the original platform was significantly reduced, the time spent in the target quadrant was shortened, the apoptosis rate of neurons was increased, and the expression of NLRP3 and Bax was up-regulated, and the expression of Bcl-2 was down-regulated in CN group ( P<0.05). Conclusions:The NLRP3 inflammasome is involved in curcumin-induced reduction of postoperative cognitive dysfunction in sevoflurane-anesthetized rats.

Objective To investigate the clinical value of extracellular volume(ECV)based on CT delayed phase in combination with pathologic indicators in predicting early recurrence of gastric mesenchymal tumors after surgery.Methods A retrospective case-control trial was conducted on the imaging,clinical and pathological data of 110 patients with gastric mesenchymal tumors who were surgically resected at the First Affiliated Hospital of Army Medical University from January 2011 to August 2022.They were 60 males and 50 females,at a mean age of 58±10 years.All of them received preoperative multiphase dynamic CT enhancement examination of the abdomen,and ECV value was calculated with the formula:ECV=(1-hematocrit)×(△HU tumor/△HU aorta).According to the postoperative recurrence within 24 months after surgery,they were divided into early recurrence group and non early recurrence group.Statistical indexes:① Consistency analysis.② The factors affecting early recurrence after resection of gastric mesenchymal stromal tumors were analyzed and a prediction model was conducted.Delong test was used to assess the predictive value of the model.Then a nomogram was plotted based on the combines model,and calibration curves were drawn to assess the efficacy of the column charts,and decision curve analysis(DCA)was adopted to assess the value of the model for clinical application.Results ① Consistency analysis.After 2 radiologists outlined the region of interest and obtained ECV value according to the above formula,The intraclass correlation coefficient(ICC)was 0.806.② For the 110 subjected patients,21 cases of them had early recurrence,and 89 one did not.Multivariate analysis showed that ECV value,risk degree,and tumor length were independent influencing factors for predicting early recurrence.Receiver operating characteristic(ROC)curve analysis indicated that the area under the curve(AUC)value of ECV,hazard degree,and tumor length diameter in predicting early recurrence was 0.838(95％CI 0.758～0.918),0.774(95％CI 0.656～0.892),and 0.700(95％CI 0.589～0.810),respectively,and the value of their combined model was 0.899(95％CI 0.811～0.987),which was higher than that of each independent model.The sensitivity and specificity of the combined model was 85.71％and 86.52％,respectively,and the optimal cutoff value was 0.19.Delong test revealed that there was statistical difference between the combined model and the clinical model established by the hazard level(Z=6.548,P＜0.001,95％CI 0.140～0.259).Calibration curve analysis suggested that the combined model had a better fit,and DCA displayed that the combined model had a better net benefit.Conclusion The model established by ECV combined with pathological indicators has good predictive performance and can be used as a more effective predictor of early recurrence of gastric mesenchymal tumors after surgery.

【Objective】 To evaluate the clinical efficacy and safety of platelet-rich plasma(PRP) in acute achilles tendon injury by meta-analysis. 【Methods】 Literature on clinical randomized controlled trial of PRP in the treatment of acute achilles tendon injury from Wanfang database, CNKI, VIP database, The Chinese Biological Literature Database, The Chinese Clinical Trials Registry, PubMed, Embase, Cochrane and The US Clinical Trials Registry as of August 2023 were retrieved. The control group received conventional treatment for acute achilles tendon injury, while PRP treatment group received additional PRP treatment. The primary outcome measure was visual analogue pain scale, and the secondary outcome measures were the achilles tendon fracture score, maximum heel rise height, calf circumference and ankle range of motion. The quality of the literature was assessed using the Cochrane manual, and a meta-analysis of qualified literature was performed using RevMan 5.3 software. 【Results】 Seven articles were finally included, involving 421 patients with acute achilles tendon injury, including 212 patients in the PRP treatment group, and 209 patients in the conventional treatment group. The results of meta-analysis showed that there was no difference between the conventional treatment group and the PRP treatment group in terms of the visual analogue pain scale(SMD=-0.44, 95%CI: -0.94~0.06, P>0.05), calf circumference (MD=1.14, 95% CI: -1.56-3.84, P>0.05), ankle joint toe flexion range of motion (SMD=1.85, 95%CI: -1.38-5.09, P>0.05), ankle dorsiflexion range of motion(SMD=2.61, 95%CI: -0.95-6.17, P>0.05), achilles tendon fracture score (MD=-5.60, 95%CI: -15.36-4.16, P>0.05) and the maximum heel rise height (MD=-2.48, 95%CI: -5.30-0.33, P>0.05). And there was no difference in the incidence of adverse reactions between the two groups (X²=2. 455, P>0.05). 【Conclusion】 PRP injection for acute achilles tendon injury does not improve the biomechanical and clinical outcomes of patients, and the use of PRP does not increase the occurrence of adverse reactions.

Objective:To analyze the clinical epidemiological characteristics and the prognostic risk factors of patients with hemorrhagic fever with renal syndrome (HFRS).Methods:A total of 2 245 HFRS patients who were admitted to the Second Affiliated Hospital of Air Force Medical University from September 2008 to December 2021 were enrolled. Clinical epidemiological data (including gender, age, onset season, onset region, case fatality rate, et al) of HFRS patients were analyzed. The clinical epidemiological characteristics of patients with HFRS in the 2008 to 2012, 2013 to 2017, and 2018 to 2021 groups were compared. Statistical comparisons were performed using chi-square test. The Bonferroni adjusted P-value method was used for pairwise comparisons between groups, and logistic regression analysis was used to screen and evaluate the risk factors associated with the prognosis of HFRS patients. Results:The age of 2 245 HFRS patients was (42.3±15.9) years old. Most of them were male (79.24%(1 779/2 245)), and the main incidence area was Xi′an City (69.53%(1 561/2 245)). There were 132 deaths with an overall case fatality rate of 5.88%. There were 1 088 patients (48.46%) from 2008 to 2012, 647 patients (28.82%) from 2013 to 2017, and 510 patients (22.72%) from 2018 to 2021, with a mortality rate of 7.17%(78/1 088), 5.10%(33/647) and 4.12%(21/510), respectively. From 2008 to 2021, both the number of HFRS cases and the case fatality rate had shown a fluctuating downward trend. There were significant differences in case fatality rate, age distribution, onset season, and onset region among patients in the different year groups ( χ2=6.84, 49.22, 83.47 and 19.29, respectively, all P<0.05). The results of pairwise comparisons showed that the proportion of patients aged >60 years in the 2018 to 2021 group (23.33%(119/510)) was higher than those in the 2008 to 2012 group (12.13%(132/1 088)) and the 2013 to 2017 group (12.36%(80/647)), and the differences were statistically significant (both P<0.05). The proportions of patients at large peak (October to December) were 62.35%(318/510) in the 2018 to 2021 group and 56.26%(364/647) in the 2013 to 2017 group, which were both lower than that in the 2008 to 2012 group (75.18%(818/1 088)), and the differences were both statistically significant (both P<0.05). The case fatality rate of patients aged >60 years was 9.67%(32/331), which was higher than those of patients aged <30 years (2.86%(16/559)) and patients aged 30 to 60 years (6.20%(84/1 355)), with statistically significant differences (both P<0.05). Univariate analysis showed that age 30 to 60 years, age >60 years, smoking, complicated with hypertension, hypotensive shock and hypoxemia were significantly correlated with the prognosis of HFRS patients (odds ratio ( OR)=2.243, 3.632, 1.484, 3.532, 79.422 and 143.955, respectively, all P<0.05). The results of multivariate logistic regression analysis indicated that complicated with hypertension ( OR=2.467, P=0.004), hypotensive shock ( OR=11.658, P=0.001), and hypoxemia ( OR=67.767, P<0.001) were the independent risk factors affecting the prognosis of HFRS patients. Conclusions:The prevalence of HFRS has shown new changing characteristics from 2008 to 2021. The numbers of HFRS patients and the case fatality rates show a downward trend, and the proportion of HFRS patients aged >60 years increases. Complicated with hypertension, hypotensive shock and development with hypoxemia are the independent risk factors for the prognosis of HFRS.

Objective:To analyze the correlation between peripheral blood eosinophil (EOS) level and clinical characteristics of patients with pneumoconiosis complicated with chronic obstructive pulmonary disease (COPD) .Methods:From January 2007 to November 2020, newly diagnosed patients with pneumoconiosis complicated with COPD in Beijing Chaoyang Hospital, were retrospectively analyzed. These patients were stratified into EOS<100 cells/μl group and EOS≥100 cells/μl group, taking 100 cells/μl as the cut-off value. Demographic characteristics, clinical symptoms, lung function and laboratory indexes were compared between the two groups.Results:The median EOS count of patients with pneumoconiosis complicated with COPD was 100 (40, 180) cells/μl. 50.2% (160/319) had blood eosinophil counts ≥100 cells/μl, and 11.0% (35/319) had blood eosinophil counts ≥300 cells/μl. In comparison with EOS<100 cells/μl group, EOS≥100 cells/μl group were older ( P=0.035), had higher body mass index ( P=0.008), and had lower forced respiratory volume in the first second ( P=0.017), had higher the ratio of residual volume to total lung volume ( P=0.010), and had lower diffusing capacity of the lung for carbon monoxide ( P=0.008). Arterial partial pressure of oxygen was significantly reduced in EOS≥100 cells/μl group ( P=0.039). The peripheral blood EOS count was negatively correlated with forced vital capacity, forced breathing volume in the first second, carbon monoxide diffusion, peak expiratory flow, and maximum mid expiratory flow as a percentage of expected values ( rs=-0.22, -0.18, -0.19, -0.19, -0.19, P=0.000, 0.001, 0.003, 0.008, 0.002), and positively correlated with the ratio of residual air volume to total lung volume ( rs=0.17, P=0.002) . Conclusion:There was a correlation between blood EOS count and pulmonary function parameters, can proide reference for the diagnosis and treatment of chnoric obstuctive pulmmory disease in clinical practice.

Objective:To evaluate the early efficacy and safety of transnasal endoscopic decompression in the annulus of zinn (AZ) region for refractory dysthyroid optic neuropathy (DON) and to preliminarily analyze the correlated factors of postoperative visual function outcome.Methods:From July 2021 to January 2023, 35 patients (56 eyes) with DON who received AZ area decompression in Peking University Third Hospital were included retrospectively, including 9 males (13 eyes) and 26 females (43 eyes), aging (52.2±12.0) years. Among them, 35 eyes underwent two-wall (medial and inferior) orbital decompression using an endonasal endoscopic approach, while 21 eyes received three-wall (medial, lateral, and inferior) orbital decompression through a combined approach. Key parameters such as best corrected visual acuity (BCVA), visual field (MD value), eyeball prominence, intraocular pressure, and complications were recorded. Postoperative data were collected one month after surgery. The statistical analysis was performed using paired t-test and Spearman correlation analysis. Results:Significant outcomes were observed post surgery in BCVA, visual field, intraocular pressure and proptosis ( t value was 8.37, 6.17, 4.50, and 9.20, respectively, all P<0.001). The reduction in proptosis was statistically significant between the 2-wall and 3-wall orbital decompression groups ( t=-2.82, P=0.007). Changes in BCVA, visual field, and intraocular pressure before and after surgery was greater in the 3-wall orbital decompression group compared to 2-wall orbital decompression group, although the difference was not statistically significant (all P>0.05). Change in postoperative visual acuity and visual field was significantly positively correlated with preoperative visual acuity and preoperative visual field (all P<0.001). Similarly, change in intraocular pressure and proptosis was positively correlated with preoperative intraocular pressure and preoperative protrusion (all P<0.001). Preoperative diplopia was reported in seven patients (20.0%), and two new cases (5.7%) were noted post-operation, which resolved within 3 months after surgery. Conclusions:Endoscopic endonasal decompression of the AZ area is a safe and effective surgical treatment for DON, with notable improvements in BCVA. Furthermore, three-orbital wall decompression seems to yield better outcomes in terms of eye retraction.

Objective To study the effects of integrated orthopedic rehabilitation pathway on motor function in six months after total knee arthroplasty (TKA), including pain, stiffness, range of motion and muscle strength, etc. Methods From March, 2016 to March, 2019, 180 patients who underwent TKA and treated with integrated orthopedic rehabilitation pathway were enrolled. Age, gender, operation time, time of follow-up, the scores of Hospital for Special Surgery-Knee Scale (HSS-KS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC) at preoperative/postoperative/one-month after operation/three-month after operation/six-month after operation time points were collected. The sub items, such as muscle strength, range of motion, flexion deformity, pain, stiffness, functional difficulty were primarily focused on. Results A total of 42 patients were followed up for three months and 22 patients were followed up for six months. There was no significant difference in the scores of HSS-KS and WOMAC before and after operation (P > 0.05). Within three months after operation, the HSS-KS scores gradually increased (P < 0.05) and the WOMAC scores gradually decreased (P < 0.05). The active knee flexion range of motion and knee extensor muscle strength scores of HSS-KS significantly decreased after operation (P < 0.05), and gradually recovered one month and three months after operation (P < 0.05). The flexion deformity scores of HSS-KS increased after operation (P < 0.05), decreased one month after operation (P < 0.05), and got a trend of incensement again three months after operation. The pain score of WOMAC decreased continuously within three months after operation (P < 0.05); the stiffness score of WOMAC did not change after operation (P > 0.05), decreased significantly one month after operation (P < 0.05), and did not change three months after operation (P > 0.05). The degree of functional difficulty of WOMAC decreased after operation (P < 0.05), and improved continuously within six months after operation (P < 0.05). Conclusion The overall function after TKA shows a trend of improvement within three months, and there is no obvious improvement from three to six months after operation. The flexion deformity score showed a downward trend in one month after operation, and it could be improved again after strengthening rehabilitation, which needs more attention in the postoperative rehabilitation.
