Objective:To observe the effect of warming needle therapy combined with Tuina(Chinese therapeutic massage)on the clinical symptoms and anxiety state of patients with cervical vertigo accompanied by anxiety. Methods:Seventy patients with cervical vertigo accompanied by anxiety state were divided into an observation group and a control group using the random number table method,with 35 patients in each group.In addition to disease education,the observation group was treated with warming needle therapy and Tuina 3 times a week,and the control group was treated with betahistine mesylate tablets orally 3 times a day.Both groups were treated for 4 weeks.The changes in the scores of the evaluation scale for cervical vertigo(ESCV),self-rating anxiety scale(SAS),and Hamilton anxiety rating scale(HAMA)were compared between the two groups after treatment. Results:One case in the observation group dropped out due to failure to cooperate with the treatment during the study.In the treatment group,the total effective rate and the cured plus markedly effective rate were 94.1%and 50.0%,respectively,and 88.6%and 8.6%in the control group,respectively;the differences between the two groups were statistically significant(P<0.05).After treatment,the ESCV,SAS,and HAMA scores of both groups decreased significantly compared with those before treatment(P<0.01),and the scores of the observation group were lower than those of the control group(P<0.01 or P<0.05). Conclusion:Warming needle therapy combined with Tuina can significantly improve the clinical symptoms of patients with cervical vertigo accompanied by anxiety state.

Objective:To compare the clinical efficacies between arthroscopic anatomic single bundle reconstruction of posterior cruciate ligament (PCL) assisted by internal tension relieving technique combined with rapid rehabilitation and anatomic single bundle reconstruction combined with conventional rehabilitation in the treatment of PCL rupture.Methods:A retrospective cohort study was used to analyze the clinical data of 88 patients with PCL rupture admitted to First Affiliated Hospital of Kunming Medical University from September 2016 to September 2020. The patients included 65 males and 23 females, aged 18-55 years [(39.3±10.8)years]. Forty-four patients underwent arthroscopic anatomic single bundle reconstruction of PCL assisted by internal tension relieving technique combined with rapid rehabilitation therapy (tension-relieving group), and 44 patients underwent arthroscopic routine anatomic single bundle reconstruction of PCL combined with conventional rehabilitation (traditional group). The two groups were compared before and at 3, 12, and 24 months after surgery regarding the following items: International Knee Literature Committee (IKDC) score, Hospital for Special Surgery (HSS) score, Lysholm score, knee motion cycle (maximum stride length, minimum stride length, and stride frequency) and 6 kinematic indicators (angle of forward and back extension, angle of internal and external rotation, angle of internal and external rotation, up and down displacement, internal and external displacement, and forward and back displacement). The Marburger arthroscopy score (MAS) and Professor Ao Yingfang′s improved score by secondary arthroscopy were compared between the two groups at 12 months after surgery. The perioperative complications were observed.Results:All patients were followed for 24-36 months [(25.5±6.3)months]. In tension-relieving group and the traditional group, the values of IKDC score were (71.8±9.8)points and (68.5±6.5)points at 3 months after surgery, (87.6±6.0)points and (87.6±5.5)points at 12 months after surgery, and (95.5±3.1)points and (92.8±11.6)points at 24 months after surgery, respectively. The values were gradually increased, significantly higher than those before surgery [(48.1±16.9)points and (47.1±15.0)points] (all P<0.05). There were no significant differences between the two groups at each time point (all P>0.05). In tension-relieving group and the traditional group, the values of HSS score were (74.2±6.2)points and (68.4±9.5)points at 3 months after surgery, (91.9±5.4)points and (88.4±4.7)points at 12 months after surgery, and (97.1±2.0)points and (96.2±2.8)points at 24 months after surgery, respectively. The values of HSS score gradually increased, significantly higher than those before surgery [(57.5±17.7)points and (56.8±14.3)points] (all P<0.05). At 3 and 12 months after surgery, the values of HSS score in the tension-relieving group were significantly higher than those in the traditional group (all P<0.05), but others were not significantly different between the two groups (all P>0.05). In tension-relieving group and the traditional group, the values of Lysholm score were (74.2±14.9)points and (70.3±7.5)points at 3 months after surgery, (90.9±6.1)points and (88.7±4.7)points at 12 months after surgery, and (96.9±3.0)points and (96.3±2.8)points at 24 months after surgery, respectively. The values of Lysholm score were gradually increased, significantly higher than those before operation [(48.7±20.7)points and (48.2±19.9)points] (all P<0.05). There were no significant differences between the two groups at any time points (all P>0.05). At 3, 12, and 24 months after surgery, the motion cycle (maximum stride length, minimum stride length and stride frequency) and 6 kinematic indicators (angle of forward bending and backward extension, angle of internal and external rotation, angle of internal and external rotation, internal and external displacement, up and down displacement, and forward and backward displacement) of knee joint were significantly improved in both groups compared with those before surgery (all P<0.05). At 3, 12, and 24 months after surgery, the forward and backward displacement in the tension-relieving group was significantly decreased than that in the traditional group (all P<0.05), but others were not significantly different between the two groups (all P>0.05). The MAS was rated as excellent to good in 14 patients and fair to poor in 2, with the excellent and good rate of 87.5% (14/16) in the tension-relieving group, while the score was rated as excellent to good in 11 patients and fair to poor in 3, with the excellent and good rate of 78.6% (11/14) in the traditional group ( P>0.05). The Professor Ao Yingfang′s improved score was (10.6±1.5)points in the tension-relieving group, markedly higher than that in the traditional group [(9.6±2.3)points] ( P<0.05). No perioperative complications were observed. Conclusion:Compared with anatomic single bundle reconstruction combined with conventional rehabilitation, arthroscopic anatomic single bundle reconstruction of PCL assisted by internal tension relieving technique combined with rapid rehabilitation have higher subjective function score, better anteroposteric stability during knee movement, and better results of secondary microscopy.

OBJECTIVE: To investigate the changes of knee joint kinematics after anterior cruciate ligament (ACL) reconstruction assisted by personalized femoral positioner based on the apex of deep cartilage (ADC). METHODS: Between January 2021 and January 2022, a total of 40 patients with initial ACL rupture who met the selection criteria were randomly divided into the study group (using the personalized femoral positioner based on ADC design to assist ACL reconstruction) and the control group (not using the personalized femoral positioner to assist ACL reconstruction), with 20 patients in each group. Another 20 volunteers with normal knee were collected as a healthy group. There was no significant difference in gender, age, body mass index, and affected side between groups ( P>0.05). Gait analysis was performed at 3, 6, and 12 months after operation using Opti _ Knee three-dimensional knee joint motion measurement and analysis system, and the 6 degrees of freedom (flexion and extension angle, varus and valgus angle, internal and external rotation angle, anteroposterior displacement, superior and inferior displacement, internal and external displacement) and motion cycle (maximum step length, minimum step length, and step frequency) of the knee joint were recorded. The patients' data was compared to the data of healthy group. RESULTS: In the healthy group, the flexion and extension angle was (57.80±3.45)°, the varus and valgus angle was (10.54±1.05)°, the internal and external rotation angle was (13.02±1.66)°, and the anteroposterior displacement was (1.44±0.39) cm, the superior and inferior displacement was (0.86±0.20) cm, and the internal and external displacement was (1.38±0.39) cm. The maximum step length was (51.24±1.29) cm, the minimum step length was (45.69±2.28) cm, and the step frequency was (12.45±0.47) step/minute. Compared with the healthy group, the flexion and extension angles and internal and external rotation angles of the patients in the study group and the control group decreased at 3 months after operation, and the flexion and extension angles of the patients in the control group decreased at 6 months after operation, and the differences were significant ( P<0.05); there was no significant difference in the other time points and other indicators when compared with healthy group ( P>0.05). In the study group, the flexion and extension angles and internal and external rotation angles at 6 and 12 months after operation were significantly greater than those at 3 months after operation ( P<0.05), while there was no significant difference in the other indicators at other time points ( P>0.05). There was a significant difference in flexion and extension angle between the study group and the control group at 6 months after operation ( P<0.05), but there was no significant difference of the indicators between the two groups at other time points ( P>0.05). CONCLUSION Compared with conventional surgery, ACL reconstruction assisted by personalized femoral positioner based on ADC design can help patients achieve more satisfactory early postoperative kinematic results, and three-dimensional kinematic analysis can more objectively and dynamically evaluate the postoperative recovery of knee joint.

OBJECTIVE: To investigate the effectiveness of anterior cruciate ligament (ACL) reconstruction assisted by personalized femoral locator based on the apex of deep cartilage (ADC) combined with patient imaging data. METHODS: Between January 2021 and January 2022, a total of 40 patients with primary ACL rupture were selected and randomly divided into study group (ACL reconstruction assisted by personalized femoral locator based on ADC) and control group (ACL reconstruction assisted by intraoperative fluoroscopy and traditional femoral locator), with 20 cases in each group. There was no significant difference in gender, age, body mass index, affected side, cause of injury, and preoperative International Knee Documentation Committee (IKDC) score, Lyshlom score, and Tegner score between the two groups ( P>0.05). IKDC score, Lyshlom score, and Tegner score were used to evaluate the functional recovery of the affected knee before operation and at 3, 6, and 12 months after operation. CT scan and three-dimensional reconstruction were performed before and after operation to measure the horizontal distance from ADC to the anterior cartilage margin (L) and the horizontal distance from ADC to the center of the femoral canal (I), and the anteroposterior position of the bone canal (R) was calculated by I/L; the distance from the center to the distal cartilage margin (D) was measured on the two-dimensional cross section; the R value and D value were compared between the two groups. RESULTS: The operation time of the study group was significantly less than that of the control group [ MD=-6.90 (-8.78, -5.03), P<0.001]. The incisions of the two groups healed by first intention, and no complication such as intra-articular infection, nerve injury, and deep vein thrombosis of lower limbs occurred. There was no significant difference in the R value and D value between the preoperative simulated positioning and the actual intraoperative positioning in the study group [ MD=0.52 (-2.85, 3.88), P=0.758; MD=0.36 (-0.39, 1.11), P=0.351]. There was no significant difference in the actual intraoperative positioning R value and D value between the study group and the control group [ MD=1.01 (-2.57, 4.58), P=0.573; MD=0.24 (-0.34, 0.82), P=0.411]. The patients in both groups were followed up 12-13 months (mean, 12.4 months). The IKDC score, Lysholm score, and Tegner score of the two groups increased gradually with time, and there were significant differences between pre- and post-operation ( P<0.05). There was no significant difference in the scores between the two groups at each time point after operation ( P>0.05). CONCLUSION The personalized femoral locator based on ADC can accurately assist the femoral tunnel positioning in ACL reconstruction, which can shorten the operation time when compared with traditional surgical methods, and achieve satisfactory early effectiveness.

OBJECTIVE To investigate the inhibitory effect and the possible mechanism of hydrogen sulfide （H2S） on the proliferation of cardiac fibroblasts. METHODS The heart of neonatal SD rats was collected， and cardiac fibroblasts were separated with differential centrifugation. Using sodium hydrosulfide as the donor of H2S， the effects of H2S on the proliferation of cardiac fibroblasts induced by angiotensin Ⅱ （Ang Ⅱ）， hydroxyproline content and the expression of sirtuin 3 （SIRT3） protein were detected. After SIRT3 knockdown with siRNA technology， the effects of H2S on the proliferation of cardiac fibroblasts induced by Ang Ⅱ， hydroxyproline content， the expressions of collagen Ⅰ （Col Ⅰ）， collagen Ⅲ （Col Ⅲ ） and optic atrophy protein 1 （OPA1） were detected. RESULTS H2S could inhibit the proliferation of Ang Ⅱ-induced cardiac fibroblasts， reduce the content of hydroxyproline and increase the expression of SIRT3 （P＜0.05）. After down-regulating the expression of SIRT3 with siRNA technology， the inhibition of H2S on the proliferation of Ang Ⅱ-induced cardiac fibroblasts and the reduction of hydroxyproline content were both inhibited， and the effect of H2S on reducing the expression of Col Ⅰ and Col Ⅲ and enhancing the expression of OPA1 was also significantly weakened. CONCLUSIONS H2S inhibits the proliferation of Ang Ⅱ -induced cardiac fibroblasts through increasing the expression of SIRT3.

Colorectal tumors often create an immunosuppressive microenvironment that prevents them from responding to immunotherapy.Cannabidiol(CBD)is a non-psychoactive natural active ingredient from the cannabis plant that has various pharmacological effects,including neuroprotective,antiemetic,anti-inflammatory,and antineoplastic activities.This study aimed to elucidate the specific anticancer mechanism of CBD by single-cell RNA sequencing(scRNA-seq)and single-cell ATAC sequencing(scATAC-seq)technologies.Here,we report that CBD inhibits colorectal cancer progression by modulating the suppressive tumor microenvironment(TME).Our single-cell transcriptome and ATAC sequencing results showed that CBD suppressed M2-like macrophages and promoted M1-like macrophages in tumors both in strength and quantity.Furthermore,CBD significantly enhanced the interaction between M1-like macrophages and tumor cells and restored the intrinsic anti-tumor properties of macrophages,thereby preventing tumor progression.Mechanistically,CBD altered the metabolic pattern of macro-phages and related anti-tumor signaling pathways.We found that CBD inhibited the alternative acti-vation of macrophages and shifted the metabolic process from oxidative phosphorylation and fatty acid oxidation to glycolysis by inhibiting the phosphatidylinositol 3-kinase-protein kinase B signaling pathway and related downstream target genes.Furthermore,CBD-mediated macrophage plasticity enhanced the response to anti-programmed cell death protein-1(PD-1)immunotherapy in xenografted mice.Taken together,we provide new insights into the anti-tumor effects of CBD.

Objective:To study the protective effect of neoeriocitrin on PC12 cell injury induced by amyloid β protein fragment 25-35 (Aβ 25-35), and explore its role in preventing and treating AD. Methods:The MTT method was used to detect the effect of Neoeriocitrin on the proliferation of normal PC12 cells and Aβ 25-35 damaged PC12 cells, and the intervention concentration of neoeriocitrin solution was screened. The PC12 cells were divided into the normal control group, model group, estradiol group and neoeriocitrin group according to the random number table method. The normal control group and model group were cultured with DMEM for 24 h; DMEM and 1×10 -3 μmol/L estradiol solution were added to the estradiol group; DMEM and 6×10 4 μmol/L neoeriocitrin solution were added to the neoeriocitrin group. After 2 hours of culture, except for the normal control group, the remaining groups were added with 20 μmol/L Aβ 25-35 stock solution, and the culture was continued for 22 h. AnnexinV-FITC/PI double labeling was used to detect apoptosis rate, Western blot method was used to detect estrogen receptor β (estrogen receptor β, ERβ) and p-P38/P38 protein expression. The content of acetylcholine (ACh) was detected, and the activity of Choline acetyl transferase (ChAT) and Acetylcholin esterase (AChE) in the supernatant of PC12 cells were detected. Results:Compared with the model group, the cell apoptosis rate [(8.080 ± 0.578)% vs. (18.500 ± 0.870)%] significantly decreased ( P<0.01), the expression of ERβ protein (0.348 ± 0.042 vs. 0.273 ± 0.006) significantly increased ( P<0.01), p-P38/P38 protein expression (0.372 ± 0.058 vs. 0.571 ± 0.063) significantly decreased ( P<0.01), the content of ACh [(14.319 ± 1.039) μg/mg vs. (9.157 ± 1.605) μg/mg], ChAT activity [(0.715 ± 0.053) U/mg vs. (0.280 ± 0.093) U/mg] significantly increased ( P<0.01), AChE activity [(2.607 ± 2.048) U/mg vs. (6.038 ± 1.867) U/mg] significantly reduced ( P<0.01). Conclusions:Neoeriocitrin can promote the proliferation of PC12 cells damaged by Aβ25-35, inhibit cell apoptosis, and has a certain cytoprotective effect. Its mechanism may be related to the regulation of ERβ expression and inhibition of P38 protein phosphorylation, thereby improving the function of the cholinergic system related.
