ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong （BL 40）" on neuropathic pain in a rat model of chronic constriction injury （CCI） of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups （8 rats in each group）， sham-operated group， model group， Tuina group， and blockade group. The CCI model was established in the model group， Tuina group， and the blockade group by ligating the sciatic nerve with catgut， while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14， rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong （BL 40）" using a dynamic pressure distribution measurement system （5 N pressure， 2 Hz frequency， 10 min per session， once daily）. The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline （10 mg/kg） once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold （MWT） and paw withdrawal latency （PWL） were measured before surgery and on day 3， 7， 10， and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair， measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 （Iba-1）， CD206， CD68， interleukin-10 （IL-10）， and β-endorphin （β-EP） precursor pro-opiomelanocortin （POMC） in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group， the model group showed significantly reduced MWT and PWL on day 3， 7， 10， and 14 （P＜0.01）. Compared with the model group， the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 （P＜0.05）. Compared with the Tuina group， the blockade group exhibited higher MWT on day 7， 10， and 14， and higher PWL on day 10 （P＜0.05）. Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group， while the model group exhibited myelin collapse， distortion， and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse， whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group， the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn （P＜0.05 or P＜0.01）. Compared with the model group， the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally， the Tuina group showed elevated levels of CD206， IL-10， and POMC， whereas the blockade group had decreased CD206 levels （P＜0.05）. ConclusionTuina at "Weizhong （BL 40）" alleviates neuropathic pain in CCI rats， potentially by regulating microglial activation in the spinal cord， inhibiting M1 polarization while promoting M2 polarization， and activating the IL-10/β-EP pathway to exert analgesic effects.

OBJECTIVE To explore the protective effect and mechanism of Longshengzhi capsules on cerebral ischemia- reperfusion injury in rats. METHODS The model of middle cerebral artery occlusion （MCAO） was established by using the improved thread occlusion method. The experiment was divided into six groups： sham surgery group （only separating blood vessels without inserting thread plugs， given the same volume of normal saline）， model group （modeling， given the same volume of normal saline）， nimodipine group （positive control， modeling， dose of 20 mg/kg）， and low-dose， medium-dose， and high-dose groups of Longshengzhi capsules （modeling， doses of 0.72， 1.44 and 2.88 g/kg， respectively）， with 10 mice in each group. Each group was given corresponding medication solution/normal saline by gavage， once a day， for 7 consecutive days. One hour after the last administration， the Zea Longa scoring method was used to score the neurological deficits in each group of rats， and the ABC enzyme-linked immunosorbent assay was used to detect the serum levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in rats； TTC staining was used to observe the volume of cerebral infarction in rats and calculate the cerebral infarction volume ratio. Hematoxylin eosin staining was used to observe the pathological changes in the brain tissue of rats. Immunohistochemical staining was used to detect the positive expression of NLRP3 protein in the brain tissue of rats. Real-time fluorescence quantitative PCR was used to detect mRNA relative expressions of Toll-like receptor 4 （TLR4） and nuclear factor-κB （NF-κB） in the brain tissue of rats. Western blot assay was adopted to detect the relative expressions of TLR4， NLRP3 and phosphorylated NF-κB （p-NF-κB） protein in the brain tissue of rats and its intracellular NF-κB protein. RESULTS Compared with the sham surgery group， the neural dysfunction score， serum levels of TNF-α and IL-6， cerebral infarction volume ratio， relative expression levels of NF-κB and TLR4 mRNA， as well as protein relative expressions of TLR4， NLRP3 and p-NF-κB in the brain tissue， and relative protein expression of intracellular NF-κB were increased significantly in the model group （P＜0.01）； the enlarged gap and significant edema were observed in cortical nerve cells of brain tissue in rats， with a large amount of inflammatory cell infiltration； the positive expression of NLRP3 protein in brain tissue of rats obviously increased. Compared with the model group， the levels of the above indicators in the medium-dose and high-dose groups of Longshengzhi capsules， as well as the Nimodipine group， were reversed to varying degrees， and most differences were statistically significant （P＜0.05 or P＜0.01）； the pathological morphology observation showed a significant improvement， and the positive expression of NLRP3 protein in the brain tissue of rats was obviously reduced. CONCLUSIONS Longshengzhi capsules may inhibit TLR4/NF-κB/NLRP3 signaling pathway and neuroinflammatory response， thereby achieving a protective effect against cerebral ischemia-reperfusion injury in rats.

Objective To explore the association between mammalian sterile 20-like kinase 1(MST1)gene poly-morphism and haplotype and the risk of colorectal cancer,rectal cancer,and colon cancer in the Han population in Baotou area by case-control association study.Methods A total of 390 patients with colorectal cancer diagnosed by pathology and 413 normal physical examination population were collected,and 2 ml of peripheral blood was taken for subsequent gene genotyping.Single nucleotide polymorphisms(SNPs)of MST1 gene were screened according to the genetic polymorphism data of Chinese Han population provided by the National Center for Biotechnology In-formation-Haplotype Mapping database.Gene genotyping was performed by Taqman method.Logistic regression was used to calculate the association between each SNP and the risk of colorectal cancer,colon cancer,and rectal cancer under codominant,dominant,overdominant,and recessive genetic models.Results Four SNPs of MST1 gene were screened,namely rs8000,rs2234197,rs2267853,and rs6073629.Among them,SNP rs2234197 was associated with the risk of rectal cancer.Compared with the GG+AA genotype,the AG genotype could reduce the risk of rectal cancer,OR[95%confidence interval(CI)]=0.657(0.442-0.976).SNP rs8000 was associated with the risk of colon cancer.Compared with the TT+GT genotype,the GG genotype could reduce the risk of colon cancer[OR(95%CI)=0.425(0.182-0.992)].Conclusion MST1 gene SNP rs2234197 AG genotype and SNP rs8000 GG genotype may be protective factors for rectal cancer and colon cancer,respectively.

Objective To investigate the associations of the single nucleotide polymorphism (SNP) rs2304733 in TEA domain transcription factor 1 (TEAD1) , rs7135838 and rs1990330 in TEA domain transcription factor 4 (TEAD4) genes with the risk of non-cardia gastric carcinogenesis.Methods Enzyme linked immunosorbent assay (ELISA) was used to detect specific antibodies against Helicobacter pylori(Hp) in serum samples of the normal con-trol group.470 normal controls were divided into Hp infection negative group (n=223) and positive group (n=247) based on antibody titers.In the 450 non-cardia gastric cancer cases and 470 controls, polymerase chain reac-tion-restriction fragment length polymorphism (PCR-RFLP) was used to genotype the each SNP locus.The uncon-ditional Logistic regression method was used to evaluate the associations between each SNP locus and the risk of non-cardia gastric carcinogenesis.Results The SNPs of TEAD1 and TEAD4 were not associated with Hp infec-tion.TEAD1 rs2304733 was associated with the risk of non-cardia gastric cancer.Compared with the carriers of TT genotype, the carries of CT and CC genotypes had an increased risk of non-cardia gastric cancer (CT vs TT:OR=2.321 , 95％CI:1.690-3.188;CC vs TT:OR=5.140 , 95％CI:1.080-24.463) .TEAD4 rs1990330 was as-sociated with the risk of non-cardia gastric cancer.Compared with the carriers of GG genotype, those with GT geno-type had an increased risk of non-cardia gastric cancer (OR = 2.405 , 95％ CI: 1.480 - 3.908) .TEAD4 rs7135838 was not associated with the risk of non-cardia gastric cancer.TEAD1 rs2304733, TEAD4 rs7135838 and rs1990330 had interaction effects on the risk of non-cardia gastric cancer (P<0.05).Conclusion In Baotou Han population, TEAD1 rs2304733 and TEAD4 rs1990330 do not play a major role in Hp infection, but may play a role in the risk of non-cardia gastric cancer.TEAD4 rs7135838 may not play a major role in the risk of Hp infec-tion and non-cardia gastric cancer.TEAD1 rs2304733 and TEAD4 rs1990330 have the strongest synergistic effect on the risk of non-cardia gastric cancer, which is the best interaction model.

Objective:To investigate the diagnosis of dual-energy X-ray absorptiometry(DXA)for osteoporosis(OP)of postmenopausal patients with rheumatoid arthritis(RA)in Qinghai region and the risk factors of them.Methods:A total of 200 postmenopausal female RA patients who admitted to Qinghai Hospital of Traditional Chinese Medicine from May 2022 to April 2023 were selected.All patients were tested for bone mineral density(BMD)after admission,and lumbar spines L1-L4,whole lumbar,large trochanter,Ward's triangle area,whole body and whole forearm were measured by DXA.According to the results of BMD test,patients whose BMD T values of all body parts-2.5 SD were less or equal to-2.5 were included in the OP group(121 cases),and patients whose BMD T value of all body parts were larger than-2.5 SD were included in the non-OP group(79 cases).The BMD T value of different body parts between two groups of RA patients were compared and analyzed.The area under curve(AUC)of receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficiency of BMD T value for OP.The logistic regression method was adopted to analyze the risk factors that postmenopausal RA patients of Qinghai region occurred OP.Results:The BMD T values of L1,L2,L3,L4,whole lumbar,large trochanter,Ward's triangular area,whole body and whole forearm of OP group were obviously lower than those of the non-OP group.In analysis of ROC curve,the sensitivities of BMD T values of L1,L2,L3,L4,whole lumbar,large trochanter,Ward's triangle area,whole body and forearm were respectively 96.20%,95.22%,90.16%,96.03%,92.01%,89.36%,99.26%,90.02% and 96.03% in diagnosing OP,and the specificities of them were respectively 81.00%,82.19%,85.22%,83.06%,83.06%,90.22%,80.06%,86.23%,83.09%,and the AUC values of them were respectively 0.908,0.905,0.896,0.906,0.903,0.879,0.918,0.901 and 0.906.The results of the logistic-regression analysis showed that advanced age,long disease course,rheumatic activity scores of 28 joints,erythrocyte sedimentation rate and Calcium supplementation were the risk factors of occurring OP in postmenopausal RA patients in Qinghai region.Conclusion:The DXA method that detects BMD of RA patients who occur OP can be used as gold standard to assess OP,and there are many risk factors that affect the occurrence of OP in postmenopausal RA patients of Qinghai region.The clinical work should combine with relative factors to formulate reasonable measure so as to reduce the incidence of OP.

Objective: To analyze the clinical application of manual therapy (MT) to tumor-related adverse reactions via summarizing the research at home and abroad, in order to provide more theoretical evidence for the clinical promotion of MT. Methods: We searched 7 Chinese and English databases, including China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed, Excerpta Medica Database (EMBASE), Ovid and EBSCO. The publication date was between the establishment date of the database and December 31, 2020. We screened the literature according to the inclusion and exclusion criteria, and then sorted and analyzed the selected information. Results: A total of 46 papers were analyzed. Most studies focused on the adverse reactions in breast cancer patients. MT interventions demonstrated the best efficacy for fatigue, followed by pain, depression and anxiety. In different MT interventions, Tuina (Chinese therapeutic massage) was mainly adopted for fatigue, pain, anxiety, depression, and limb dysfunctions. Acupoint pressing was mainly adopted for gastrointestinal and psychological problems such as abdominal bloating, insomnia, depression and anxiety. The application of reflexotherapy was similar to that of Tuina. Conclusion: MT can alleviate various adverse reactions by effectively relieving patients' somatic symptoms and improving their psychological states and overall functions. It can be popularized as a significant non-drug therapy. Currently, however, the clinical application of MT is neither extensive nor has sufficient basic research. Consequently, we should attach importance to this application.

Objective To study changes in kinematics and joint coordination of the waist and hips during sit-to-stand and stand-to-sit tasks in patients with lumbar disc herniation (LDH). Methods The Vicon 3D motion capture system was used to collect the kinematics data from 20 healthy controls and 20 LDH subjects, and differences in movement patterns of the lumbar spine and hip joints during sitting and standing tasks were compared between two groups through statistical parametric mapping (SPM). Results During sit-to-stand task, the lumbar spine flexion and extension range and hip joint abduction angle of LDH subjects were significantly limited, and the hip flexion angle increased. SPM analysis showed that for both groups at initial stage of sit-to-stand (10%-13%), there was a statistically significant difference in flexion angle of the lumbar spine, and lumbar flexion angle of LDH subjects was significantly reduced, while hip flexion angle at 2%-14% phase was significantly increased. During stand-to-sit phase (65%-69%), LDH subjects showed increased hip abduction angle. Conclusions LDH subjects have limited lumbar flexion and hip abduction functions during sitting and standing, and they need to be compensated with increased hip flexion activities to complete functional tasks. In clinical evaluation, changes in motor function of the spine and hips should be focused on.
