Our study provided the evidence of detecting the specific antigen of M. tuberculosis to be used in diagnosing tuberculosis.

Objective To observe any short-term analgesic effect of using heat stimulation at acupoints for treating migraine headaches without aura.Methods Totally 120 migraine patients were randomly divided into an observation group and a control group,each of 60.Both groups was given 5mg of Sibelium orally each night for 4 weeks.The observation group additionally received heat and pain stimulation at the Feng Chi,Shuai Gu,Yang Ling Quan,Wai Guan,Tai Yang and Yin Tang acupoints.The heat was in 0.3 s pulses at 54.5° with an inter-pulse interval of 10 s.Each acupuncture point was stimulated 5 times in rotation for a total of 20 min daily for 4 weeks.The frequency of headache attacks,their duration,their intensity rated using a visual analogue scale (VAS),accompanying symptoms and responses to a migraine-specific quality of life questionnaire (MSQ) were recorded before and after the treatment.Results After the treatment there was significantly greater improvement in the observation group compared to the control group in terms of headache frequency,headache duration,VAS ratings,and accompanying symptoms.The observation group also improved significantly more in terms of the average limitation dysfunction score,dysfunction score and emotion score on the MSQ.Moreover,the total effectiveness rate of the observation group (95.0％) was significantly higher than that of the control group (80.0％).During the treatment,no adverse reactions were found in terms of heart rate or blood pressure,and no abnormal manifestations such as infection,redness or swelling were observed at the stimulation sites.Conclusion Heat and pain stimulation at acupoints has a significant short-term analgesic effect on migraine without aura.Such treatment is safe and reliable,with few side effects.It provides a new treatment method for migraine patients and is worthy of clinical promotion and application.

Objective:To assess the efficacy and safety of cinepazide maleate injection in the treatment of patients with acute ischemic stroke.Methods:A multicenter, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial, led by Peking Union Medical College Hospital, was conducted in 65 Hospitals in China. The efficacy of cinepazide maleate injection in patients with acute anterior circulation cerebral infarction with onset time of ≤48 hours, 7≤National Institute of Health stroke scale (NIHSS) score ≤25 was assessed from August 2016 to February 2019, using the proportion of modified Rankin scale (mRS) score≤1 and Barthel index (BI) score≤95 on day 14 as efficacy endpoint. The patients were divided into treatment group who were treated with cinepazide maleate injection and control group who were treated with placebo.Results:A total 937 patients were involved in the final efficacy analysis (466 in treatment group and 471 in control group). The proportion of subjects with mRS score≤1 on day 14 after treatment were higher in the treatment group than that in the control group (102/466(21.89%) vs76/471(16.14%)). Logistic regression analysis showed that patients treated with cinepazide maleate were significantly more likely to have a favorable outcome (mRS score≤1) than patients treated with placebo on day 14 ( OR=0.677, 95% CI 0.484-0.948 , P=0.023), and patients treated with cinepazide maleate were more likely to reach independence in activities of daily living (Barthel Index ≥95) than those treated with placebo on day 14 (125/466(26.82%) vs 91/471(19.32%); OR=0.632, 95% CI0.459-0.869, P=0.005). The rate of adverse events was similar between the treatment and control groups. Conclusion:The 14-day treatment with cinepazide maleate injection could reduce the degree of disability whereas did not increase the risk of adverse events.

Objective:To investigate the early and middle term clinical efficacies of 3D-printed metal prostheses in the reconstruction of bone defects after osteotomy in malignant bone tumors.Methods:A total of 34 patients with malignant bone tumors of lower extremity femur and tibia who underwent 3D printing individualized metal prosthesis replacement surgery in the Department of Bone and Soft Tissue of Affiliated Cancer Hospital of Zhengzhou University from March 2019 to March 2022 were retrospectively analyzed. There were 23 males and 11 females, with an average age of 19.1±15.2 years (range, 7-80 years). There were 22 children and adolescents younger than 18 years old. There were 3 cases in the proximal femur, 15 cases in the middle and distal femur, 10 cases in the proximal tibia and 6 cases in the distal tibia. According to the final pathological diagnosis, 24 cases of osteosarcoma, 6 cases of Ewing's sarcoma, 2 cases of undifferentiated sarcoma, 1 case of osteosarcoma, and 1 case of malignant giant cell tumor of bone were enrolled in this study. Postoperative complications, wound healing, periprosthetic fracture and aseptic loosening, tumor outcome (evaluated by tumor control evaluation criteria), and length difference of lower limbs were recorded. Response evaluation criteria in solid tumor (RECIST) was used to evaluate tumor outcomes. Prosthetic-bone interface healing was evaluated postoperatively, and the function was evaluated based on Musculoskeletal Oncology Society (MSTS) 93.Results:The length of lesions was 70-240 mm in 34 patients, with an average of 125.5±35.4 mm. The length of osteotomy was 80-275 mm, with an average of 160.2±33.9 mm. No tumor was found on the osteotomy surface. The customized prosthesis was firmly installed and closely matched with the side of the preserved articular surface. There were 2 patients with local incision fat liquefaction and 4 patients with superficial wound infection, which healed after debridement and antibiotic treatment. One distal tibia osteosarcoma case developed severe periprosthetic infection 2 months after surgery, resulting in prosthesis implantation failure, limb movement pain and poor ankle function. After removal of the prosthesis, infection control and osteogenesis with the Ilizarov technique, the infection was completely controlled and local osteogenesis was possible. The remaining 33 patients had a good prosthetic-bone interface union. One case was found to have localized bone resorption on the contact surface of the prosthesis 7 months after operation, but the metal prosthesis and screws were not loose. The incisions healed well in other patients, without infection, prosthesis loosening, fracture or other complications. All patients survived and were followed up for 13.8±5.6 months (range, 7-27 months). During the follow-up, there was no recurrence of tumor at the osteotomy end in all patients, but 5 patients developed lung metastasis. At the end of the last follow-up, all patients survived. Among them, 16 patients had unequal length of lower limbs, including 10 cases within 2 cm, 3 cases between 2-5 cm, and 3 cases over 5 cm. With the exception of one patient whose prosthesis was removed due to infection, the MSTS 93 of the other patients was 24.9±2.2 (range, 19-28), and were rated as excellent in 26 cases and good in 7 cases. According to the RECIST evaluation criteria, 26 of 34 patients had complete response, 5 had disease progression, and 3 had stable disease.Conclusion:3D printed metal prosthesis is one of the effective methods for the treatment of bone defects after resection of malignant bone tumors in lower limbs, which is safe, reliable and has satisfactory early curative effect.

Schizophrenia has various obstacles in cognition， thinking， emotion， behavior and other aspects； it belongs to the category of “madness” in traditional Chinese medicine （TCM）. Once schizophrenia occurs， multiple factors are often intertwined， and a single therapy is difficult to be effective. At present， TCM compounds and active ingredients have significant effects in the clinical treatment of schizophrenia， which is an important direction for the development of new drugs for schizophrenia. This article summarizes the molecular mechanism of TCM compounds and active ingredients in the treatment of schizophrenia. It is found that Wendan decoction and Yudian decoction can inhibit the apoptosis of hippocampal cells by activating BDNF/TrKB/CREB signaling pathway； quercetin and icariin can promote neural development and regeneration by activating NMDA/ERK signaling pathway； Wendan decoction and icariin can maintain neural cell homeostasis by activating PI3K/AKT signaling pathway； Bushen zhuangyang capsule can enhance learning and memory abilities by activating CaMKⅡ signaling pathway； formulas such as Huatan huoxue tongzhi formula can enhance intercellular information transmission by inhibiting PKC signaling pathway； α-humulene and others can restore nerve cell function by inhibiting NRG1/ErbB4 signaling pathway. TCM compounds and active ingredients can improve schizophrenia by intervening in the above-mentioned signaling pathways.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

ObjectiveTo observe the effects of Yuejuwan in the treatment of psychological and heart diseases （PHD） and explore its mechanism. MethodThirty 6-week-old healthy male SPF AopE^-/- mice and 10 homologous C57BL/6J mice were selected for the experiment. The 30 AopE^-/- mice were divided into a model group， low-dose （7.58 g·kg^-1·d^-1） and high-dose （30.32 g·kg^-1·d^-1） Yuejuwan groups， with 10 mice in each group， and 10 C57BL/6J mice were assigned to the blank control group. Intragastrical administration lasted 12 weeks. During feeding， the PHD model was induced by chronic unpredictable mild stress （CUMS） combined with high-fat diet in mice. After intragastric administration， the behavioral results ［open field test （OFT） and sucrose preference test （SPT）］ of mice in each group， the content of aspartic transaminase （AST）， alanine aminotransferase （ALT）， 5-hydroxytryptamine （5-HT）， noradrenaline （NE）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， total cholesterol （TC）， and triglyceride （TG） in serum of mice detected by the automatic biochemical analyzer， the oil red O staining and HE staining of aorta and liver and Masson staining of myocardial tissues were used for model evaluation. Finally， liver TMT-labeled quantitative proteomics was used to explore the mechanism of action. ResultThe model mice showed obvious manifestations of depression， anxiety， loss of interest， and despair， manifest lipid deposition in the aorta and liver by pathological observation， and increased myocardial fibrosis in myocardial tissues. After intragastric administration of Yuejuwan， the above symptoms and indexes of the PHD model mice were improved. Compared with the blank control group， the model group showed decreased standing times， cumulative time in the central area， total moving distance， moving speed， and sucrose preference at week 12 （P<0.01）. Compared with the model group， the Yuejuwan groups showed decreased indexes mentioned above （P<0.01）. After sample collection， AST， ALT， and TG levels in the model group were higher （P<0.01） and the levels of 5-HT， NE， and HDL-C were lower than those in the blank control group （P<0.01）. The results of liver TMT labeled quantitative proteomics suggested that the PHD model mainly caused the changes in protein expression levels such as ApoE， UGT1A5， and FASN in mice，involving acetyl CoA metabolism，response to bacteria，cellular amino acid catabolism， and other processes，which were related to the abnormal metabolic function of the liver. The efficacy of Yuejuwan against PHD was achieved mainly through the regulation of high mobility group nucleosomal-binding domain 2 （HMGN2）， CALD1， and Mup7 protein expression levels and correcting the biological processes and abnormal pathways related to the pathogenesis of PHD，including muscle contraction，tight junction pathway，myocardial contraction pathway，and focal adhesion pathway. ConclusionCUMS combined with high-fat diet is reasonable in the induction of the PHD model in AopE^-/- mice. Yuejuwan can correct the depression and anxiety conditions of PHD model mice，reduce the aortic plaque， and recover the abnormal blood lipid and liver function levels. Furthermore， Yuejuwan can correct abnormal biological processes and pathways of PHD model mice. The differential proteins screened throughout the experiment and the involved physiological and pathological changes are the focus of the next experiment.
