Rheumatoid arthritis （RA）， as an autoimmune disease， is mainly characterized by persistent synovitis. It often involves multiple joints symmetrically and can lead to joint deformity， joint function loss， and even disability in severe cases. The pathogenesis of RA is complex， and the prevention and treatment are complicated. Therefore， it is difficult to cure the disease completely. Previous studies have validated important targets and mechanisms for the prevention and treatment of RA， including the nuclear factor-κB （NF-κB） signaling pathway that controls the inflammatory process， nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway that regulates oxidative stress， inhibits inflammation， and maintains cell homeostasis， Wnt/β-catenin signaling pathway that plays a key role in cell growth， differentiation， apoptosis， and inflammatory response， anti-inflammatory， anti-oxidation， and silent information regulator 1 （SIRT1） signaling pathway that regulates synovial cells， anti-inflammatory adenylate-activated protein kinase （AMPK） signaling pathway that regulates energy metabolism， and hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF） signaling pathway related to angiogenesis in RA. At the same time， many studies have confirmed that traditional Chinese medicine prevents and treats RA by regulating the above signaling pathways and exerting their related effects， indicating the advantages of traditional Chinese medicine such as multiple regulatory pathways， long-term effects， and less adverse reactions. In this paper， by consulting many research reports， the role of the above-mentioned signaling pathways in RA was clarified， and the latest research results of traditional Chinese medicine intervention in the above-mentioned signaling pathways in the prevention and treatment of RA in recent years were summarized in detail. This paper aims to promote the in-depth study of the pathogenesis of RA and its treatment with traditional Chinese medicine， provide a scientific basis for the rational application of traditional Chinese medicine， and offer useful enlightenment for the development of new drugs and clinical practice for the treatment of RA in the future.

The concept of "holism of body and spirit" originated in the pre-Qin period as a philosophical idea to understand the world,and later became an important theory adopted in traditional Chinese medicine (TCM). Acupuncture,as a traditional TCM treatment modality,can be guided by the theory of "holism of body and spirit" in the clinical treatment of psychosomatic disorders. However,there is no clear and standardized operational model based on this theory currently. The combination of theory and practice is essential for the effective application and development of TCM. Currently,there are numerous schools and methods of acupuncture treatment for psychosomatic disorders,and the analytical perspectives on psychosomatic disorders vary,which leads to the complexity of integrating theory and practice and makes it difficult to conclude and summarize the standardized process. Given that TCM is a classical and time-honored medical science,tracing its historical origins and summarizing the diagnostic and treatment plans of different representative physicians might help in advancing acupuncture treatment for psychosomatic disorders. This paper analyzes and discusses the connection between philosophical ideas and medical theories,the application of theories into practice,and the analysis and summary of medical case literature,and puts forward the specific mode of acupuncture treatment of psychosomatic disorders,so as to provide new ideas and references for clinical practice.

Objective To evaluate the impact of optimizing the stroke green channel on the efficiency of acute ischemic stroke management in a county hospital. Methods A retrospective analysis of the emergency stroke green channel treatment data from Sixian People’s Hospital from May 2020 to April 2021 (before optimization of the green channel) and from May 2021 to April 2022 (after optimization of the green channel) was conducted. The rates of intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) patients, as well as door-to-needle time (DNT), door-to-puncture time (DPT), and the modified Rankin scale (mRS) scores of patients three months post-treatment before and after the optimization of the stroke green channel were compared. Results Within one year before and after optimization of the green channel, the number of acute visits for ischemic stroke was 3 143 and 2 623, respectively. Before optimization, 84 and 51 underwent IVT and MT, respectively. After optimization of the green channel, the ratios of patients underwent IVT (n＝215) and MT (n＝103) significantly increased, and both DNT and DPT were significantly shortened (P＜0.000 1); the proportion of MT patients with an mRS score of 0-2 at 3 months post-discharge significantly increased (46/99 vs 13/46, P＝0.038). Conclusion After optimizing the green channel at Sixian People’s Hospital, the efficiency of stroke treatment has significantly improved, and the patients’ prognosis improved.

【Objective】 To explore the mutation type, clinical characteristics, molecular genetics and the two-hit type of a patient with familial Von Hippel Lindau (VHL) syndrome. 【Methods】 The data of the patient were collected. DNA was extracted from the peripheral blood and renal cell carcinoma sample. The VHL gene germline mutation site was detected with high throughput sequencing next generation sequencing (NGS). The two-hit site was identified with UCSCXena database, methylation-specific PCR (MSP) and microsatellite stability detection. 【Results】 The mutation site of the embryo line was located in c.500G>A R167Q mutation. The patient had single nucleotide polymorphism, but no clear loss of heterozygosity, methylation or system mutation. 【Conclusion】 The germline mutation in exon 3 is the basis for the clinical features of this familial renal cell carcinoma proband. The identification of the two-hit site is key to the occurrence of the disease, which is significant for the diagnosis and treatment. The use of the databases can guide the screening of mutations and methylation sites in familial renal cell carcinoma.

Objective : Viral load is becoming more and more important in prevention of HIV/AIDS. Understanding the baseline of viral load before treatment in newly reported HIV/AIDS patients can provide a basis for AIDS prevention. Methods : The viral load of newly reported HIV/AIDS patients in Jiangsu province in 2019 was detected by fluorescence quantitative PCR , the differences of viral load under different demographic characteristics were compared , and the factors of high viral load were analyzed. Results : he mean viral load of 3098 newly reported HIV/AIDS patients in Jiangsu province was 4. 33 ± 1. 05 log/mL , and the proportion of patients with viral load < 5000 copies/mL was 20. 85% (646/3 098) . There were statistically significant differences in viral load among different genders (P < 0. 05) , and male patients had higher viral load. The difference of viral load between HIV⁃infected and AIDS patients was statistically significant (P < 0. 05) , and the viral load value of AIDS patients diagnosed with disease status was relatively high. Unmarried and married spouses were more likely to have higher viral load than divorced or widowed spouses. Higher baseline viral load level was associated with higher rates of virologic failure after antiviral therapy. Conclusion The overall viral load of HIV infected /AIDS patients is high , but there is a certain proportion of low viral load , suggesting that follow⁃up of low viral load should be strengthened in AIDS prevention and treatment. Strengthen interventions aimed at men and unmarried or married people with spouses to reduce the risk of transmission.

Objective:To investigate the construction and application value of a nomogram predictive model for the prognosis of rectal cancer liver metastases based on Surveillance, Epidemio-logy, and End Results (SEER) database.Methods:The retrospective cohort study was conducted. The clinicopathological data of 6 192 patients with rectal cancer liver metastases in the SEER database ( http://seer.cancer.gov/) and 312 patients who were admitted to The Second Affiliated Hospital of Naval Medical University January 2010 to December 2016 were collected. Of 6 192 patients, there were 3 592 males and 2 600 cases. There were 1 076 cases with age lower than 50 years, 2 862 cases with age as 50-69 years, 2 254 cases with age equal to or more than 70 years, respectively. Of 312 pati-ents, there were 177 males and 135 cases. There were 51 cases with age lower than 50 years, 155 cases with age as 50-69 years, 109 cases with age equal to or more than 70 years, respectively. Patients of the SEER database were set as the training set, and patients in The Second Affiliated Hospital of Naval Medical University were set as the validation set. Univariate and multivariate COX proportional hazards regression models were used to analyze risk factors associated with prognosis, and construct and verify the accuracy of nomogram predictive model for the prognosis of rectal cancer liver metas-tasis. The training set were used to construct the nomogram prediction model, and the validation set were used to verify its performance. Observation indicators: (1) prognostic factors analysis in patients with rectal cancer liver metastases; (2) construction and verificative of the predictive model for the prognosis of rectal cancer liver metastasis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was analyzed using the rank sum test. The COX regression model was used for univariate and multivariate analyses. Kaplan-Meier method was used to calculate survival rates, and Log-Rank test was used for survival analysis. Results:(1) Prognostic factors analysis in patients with rectal cancer liver metastases. Results of multivariate analysis showed that age >50 years, TNM Ⅱ-Ⅳ stage, stage T3-T4, stage N1-N2, the number of lymph nodes dissected <12, tumor diameter >5.1 cm, positive carcinoembryonic antigen, peripheral nerve infiltration, radiotherapy and adjuvant chemotherapy, poorly differentiated or undifferented tumor were independent prognostic factors of patients ( P<0.05). (2) Construction and verification of the predictive model for the prognosis of rectal cancer liver metastasis. A nomogram predictive model for the prognosis of rectal cancer liver metastasis was constructed based in the multivariate analysis. The C-index of the nomogram predictive model was 0.91, with area under the curve as 0.726, indicating a good discriminant ability. Results of the calibration curve in validation dataset showed that the colorectal cancer survival rate predicted by the nomogram predictive model was consistent with the actual survival rate. Conclusion:The nomogram predictive model can accurately predict the survival probability of patients with rectal cancer liver metastases.

OBJECTIVE: To analyze the correlation between bone cement cortical leakage and injury degree of osteoporotic vertebral compression fracture (OVCF) after percutaneous kyphoplasty (PKP), and to provide guidance for reducing clinical complications. METHODS: A clinical data of 125 patients with OVCF who received PKP between November 2019 and December 2021 and met the selection criteria was selected and analyzed. There were 20 males and 105 females. The median age was 72 years (range, 55-96 years). There were 108 single-segment fractures, 16 two-segment fractures, and 1 three-segment fracture. The disease duration ranged from 1 to 20 days (mean, 7.2 days). The amount of bone cement injected during operation was 2.5-8.0 mL, with an average of 6.04 mL. Based on the preoperative CT images, the standard S/H ratio of the injured vertebra was measured (S: the standard maximum rectangular area of the cross-section of the injured vertebral body, H: the standard minimum height of the sagittal position of the injured vertebral body). Based on postoperative X-ray films and CT images, the occurrence of bone cement leakage after operation and the cortical rupture at the cortical leakage site before operation were recorded. The correlation between the standard S/H ratio of the injured vertebra and the number of cortical leakage was analyzed. RESULTS: Vascular leakage occurred in 67 patients at 123 sites of injured vertebrae, and cortical leakage in 97 patients at 299 sites. Preoperative CT image analysis showed that there were 287 sites (95.99%, 287/299) of cortical leakage had cortical rupture before operation. Thirteen patients were excluded because of vertebral compression of adjacent vertebrae. The standard S/H ratio of 112 injured vertebrae was 1.12-3.17 (mean, 1.67), of which 87 cases (268 sites) had cortical leakage. The Spearman correlation analysis showed a positive correlation between the number of cortical leakage of injured vertebra and the standard S/H ratio of injured vertebra ( r=0.493, P<0.001). CONCLUSION The incidence of cortical leakage of bone cement after PKP in OVCF patients is high, and cortical rupture is the basis of cortical leakage. The more severe the vertebral injury, the greater the probability of cortical leakage.

OBJECTIVE: To investigate the feasibility of predicting proximal junctional kyphosis (PJK) in adults after spinal deformity surgery based on back-forward Bending CT localization images and related predictive indicators. METHODS: A retrospective analysis was performed for 31 adult patients with spinal deformity who underwent posterior osteotomy and long-segment fusion fixation between March 2017 and March 2020. There were 5 males and 26 females with an average age of 62.5 years (range, 30-77 years). The upper instrumented vertebrae (UIV) located at T ₅ in 1 case, T ₆ in 1 case, T ₉ in 13 cases, T ₁₀ in 12 cases, and T ₁₁ in 4 cases. The lowest instrumented vertebrae (LIV) located at L ₁ in 3 cases, L ₂ in 3 cases, L ₃ in 10 cases, L ₄ in 7 cases, L ₅ in 5 cases, and S ₁ in 3 cases. Based on the full-length lateral X-ray film of the spine in the standing position before and after operation and back-forward Bending CT localization images before operation, the sagittal sequence of the spine was obtained, and the relevant indexes were measured, including thoracic kyphosis (TK), lumbar lordosis (LL), local kyphosis Cobb angle (LKCA) [the difference between the different positions before operation (recovery value) was calculated], kyphosis flexibility, hyperextension sagittal vertical axis (hSVA), T ₂-L ₅ hyperextension C ₇-vertebral sagittal offset (hC ₇-VSO), and pre- and post-operative proximal junctional angle (PJA). At last follow-up, the patients were divided into PJK and non-PJK groups based on PJA to determine whether they had PJK. The gender, age, body mass index (BMI), number of fusion segments, number of cases with coronal plane deformity, bone mineral density (T value), UIV position, LIV position, operation time, intraoperative blood loss, osteotomy grading, and related imaging indicators were compared between the two groups. The hC ₇-VSO of the vertebral body with significant differences between groups was taken, and the receiver operating characteristic curve (ROC) was used to evaluate its accuracy in predicting the occurrence of PJK. RESULTS: All 31 patients were followed up 13-52 months, with an average of 30.0 months. The patient's PJA was 1.4°-29.0° at last follow-up, with an average of 10.4°; PJK occurred in 8 cases (25.8%). There was no significant difference in gender, age, BMI, number of fusion segments, number of cases with coronal plane deformity, bone mineral density (T value), UIV position, LIV position, operation time, intraoperative blood loss, and osteotomy grading between the two groups ( P>0.05). Imaging measurements showed that the LL recovery value and T ₈-L ₃ vertebral hC ₇-VSO in the PJK group were significantly higher than those in the non-PJK group ( P>0.05). There was no significant difference in hyperextension TK, hyperextension LL, hyperextension LKCA, TK recovery value, LL recovery value, kyphosis flexibility, hSVA, and T ₂-T ₇, L ₄, L ₅ vertebral hC ₇-VSO ( P>0.05). T ₈-L ₃ vertebral hC ₇-VSO was analyzed for ROC curve, and combined with the area under curve and the comprehensive evaluation of sensitivity and specificity, the best predictive index was hC ₇-L ₂, the cut-off value was 2.54 cm, the sensitivity was 100%, and the specificity was 60.9%. CONCLUSION Preoperative back-forward Bending CT localization image can be used to predict the occurrence of PJK after posterior osteotomy and long-segment fusion fixation in adult spinal deformity. If the patient's T ₈-L ₂ vertebral hC ₇-VSO is too large, it indicates a higher risk of postoperative PJK. The best predictive index is hC ₇-L ₂, and the cut-off value is 2.54 cm.

Objective:To investigate the influencing factors of anastomotic leakage after laparoscopic intersphincter resection (ISR) for extremely low rectal cancer and construction of nomogram prediction model.Methods:The retrospective case-control study was conducted. The clinicopathological data of 812 patients who underwent laparoscopic ISR for extremely low rectal cancer in the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) from February 2012 to February 2022 were collected. There were 459 males and 353 females, aged (51±11)years. Observation indicators: (1) surgical situations; (2) follow-up; (3) influencing factors of postoperative anastomotic leakage; (4) construction and evaluation of nomogram prediction model for postoperative anastomotic leakage. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. The COX proportional hazard model was used for univariate and multivariate analyses. The R software(3.5.1 version) was used to construct nomogram prediction model. The receiver operating characteristic (ROC) curve was drawn and the area under curve (AUC) was used to evaluate the efficacy of the nomogram prediction model. The Bootstrap method was used for internal verification and to calculate the average consistency index (C-index). Results:(1) Surgical situations. All 812 patients underwent laparoscopic ISR for extremely low rectal cancer, including 388 cases undergoing partial ISR, 218 cases undergoing subtotal ISR and 206 cases undergoing complete ISR. All 812 patients underwent ileal protective ostomy, and there were 306 cases with double anastomosis and 203 cases with left colic artery preserved, respectively. The operation time and volume of intraoperative blood loss of 812 patients was (179±33)minutes and (33±13)mL, respectively. (2) Follow-up. All 812 patients were followed up for (13.5±0.9)months. Of the 812 patients, there were 62 cases with postoperative anastomotic leakage and the healing time of these cases was (33±6)days. (3) Influencing factors of postoperative anastomotic leakage. Results of multivariate analysis showed that male, neoadjuvant chemoradiotherapy, failure of reser-ving left colic artery were independent risk factors of anastomotic leakage after laparoscopic ISR for extremely low rectal cancer ( hazard ratio=5.98, 4.00, 16.26, 95% confidence interval as 1.66-24.12, 1.30-12.42, 3.00-90.89, P<0.05). (4) Construction and evaluation of nomogram prediction model for postoperative anastomotic leakage. According to the results of multivariate analysis, male, neoadju-vant chemoradiotherapy and failure of reserving left colic artery were used to construct the nomogram prediction model for anastomotic leakage after laparoscopic ISR for extremely low rectal cancer, and the score of these indexes in the nomogram prediction model was 50, 49, 93, respectively. The total score of these index corresponded to the incidence rate of anastomotic leakage. Results of ROC curve showed that the AUC of nomogram prediction model of anastomotic leakage after laparoscopic ISR for extremely low rectal cancer was 0.87 (95% confidence interval as 0.80-0.93, P<0.05), with sensi-tivity and specificity 0.96 and 0.60, respectively. Results of internal verification showed that the C-index of nomogram prediction model was 0.87. Conclusion:Male, neoadjuvant chemoradiotherapy, failure of reserving left colic artery are independent risk factors of anastomotic leakage after laparo-scopic ISR for extremely low rectal cancer, and the nomogram prediction model based on these indexes can predict the incidence rate of postoperative anastomotic leakage.
