ObjectiveTo analyze the correlation between the clinical symptoms， signs， syndrome characteristics and laboratory indicators of cough variant asthma （CVA） and deepen the understanding of the treatment of this disease based on the theory of "Fu Feng". MethodsAn observational study was conducted. A total of 207 CVA patients who visited the respiratory department of the Third Affiliated Hospital of Beijing University of Chinese Medicine from September 2022 to November 2023 were included. The information from the four diagnostic methods and the laboratory test results of patients were collected. Factor analysis was conducted on the information obtained through the four diagnostic methods in TCM， and the nature and location of CVA were extracted. Sample cluster analysis （Q clustering） and the K-means method were used for data clustering analysis to determine the syndrome types of CVA and analyze the syndrome characteristics and differences in laboratory indicators among different syndrome types. ResultsThe main symptom of CVA patients was cough， accompanied by symptoms such as itchy throat， foreign body sensation in the throat， dry throat， shortness of breath， dry mouth， chest tightness， hoarseness， bitter mouth， poor appetite， and skin itching. Factor analysis showed that the disease was located in the lung， involving the liver， spleen， and kidney. The pathological factors involved Yin deficiency， Yang deficiency， wind factor， dampness factor， Yin factor， and Qi stagnation. Cluster analysis revealed four syndrome types： Fengfu Yinshang syndrome， Shixie Neiyun syndrome， Tanyin Zufei syndrome， and Ganhuo Fanfei syndrome. Fengfu Yinshang syndrome accounted for the highest proportion， followed by Tanyin Zufei syndrome. There were no significant differences in eosinophil count and percentage， fractional nasal nitric oxide （FnNO） level， and pulmonary function indexes among the four syndromes. The levels of serum total IgE and fractional exhaled nitric oxide （FeNO） in patients with Fengfu Yinshang syndrome were significantly higher than those in patients with Shixie Neiyun syndrome and Tanyin Zufeisyndrome. ConclusionCough is the main symptom of CVA， accompanied by pharyngeal itching， foreign body sensation in the throat， dry throat， shortness of breath， dry mouth， and allergic manifestations. The disease involves the lung， liver， spleen， and kidneys. The essence of the pathogenesis lies in a latent dormant pathogen and a disorder of the pivot mechanism. The four common syndrome types are Fengfu Yinshang syndrome， Shixie Neiyun syndrome， Tanyin Zufei syndrome， and Ganhuo Fanfei syndrome. The TCM syndrome types are correlated with laboratory indexes. The serum total IgE and FeNO of patients with Fengfu Yinshang syndrome are worse.

Objective:The purpose of this study was to investigate the clinical value of CT-guided localization of pulmonary nodules with soft wire hook-wire by trailing technique.Methods:The clinical data of 211 pulmonary nodules of 185 patients from November 2020 to March 2022 in Beijing Aerospace General Hospital were retrospectively analyzed. The pulmonary nodules were localized with soft wire hook-wire by trailing technique before video-assisted thoracic surgery (VATS). The success rate, complications, pathological results and localization operations related data were statistically analyzed.Results:The success rate of localization was 97.63% (206/211), and the success rate of VATS removal was 99.53% (210/211). The average operation time was (7.19 ± 2.62) min, and the average time required for resection of lesions was 27 min (10 to 126 min). During the surgery, the soft wire hook-wire of two patient was found to be dislocated and retracted into the chest wall. The pulmonary nodules were successfully located and removed according traces left by puncture points on the lung surface. It was found that the hook-wire was located in the interlobar fissure in 3 patients. The pulmonary nodules were successfully removed by the hook-wire position and appropriately expanding the resection range. A minor pneumothorax occurred in 49 patients, but no closed drainage was needed; 12 patients developed intrapulmonary hematoma; 15 patients with chest pain were treated with analgesia.Conclusions:For small pulmonary nodules requiring thoracoscopic surgery, the computed tomography-guided pulmonary nodule localization with soft wire hook-wire by trailing technique is more convenient, safe and effective, and is worthy of promotion to use.

Objective:To establish an animal model of acute systemic cold injury in mice.Methods:There were 98 C57BL/6 mice, half male and half female, with body weight of 22-27 g and age of 10 weeks. The mice were randomly divided into 7 groups ( n=14) according to the changes of anal temperature in cold environment, namely, group A (38.5 ± 1) ℃, group B (35 ± 1) ℃, group C (30 ± 1) ℃, group D (25 ± 1) ℃, group E (20 ± 1) ℃, group F (15 ± 1) ℃, and group G (10 ± 1) ℃, among which, group A was the blank control group, and the rest groups were the experimental group. The mice in the blank control group were placed in the normal environment (20 ± 5) ℃, and the mice in the experimental group were placed in the low temperature artificial climate box at - 20℃. The anal temperature of the mice was measured intermittently (as the core temperature), and the time required for the core temperature of the mice to drop to groups B, C, D, E, F and G was recorded. The righting reflex was used to evaluate the consciousness state, the action ability and the general state of each organ of mice were observed, and the blood routine and HE staining of each organ were detected. Results:The lower the core temperature of the experimental group, the longer the time required. The consciousness state, action ability, general state of organs, blood routine, and HE staining of organs in groups B, C, and D were basically the same as those in group A, and there was no acute systemic cold injury. Therefore, the blood routine, general observation of organs, and HE staining of organs in groups B, C, and D were no longer displayed compared with those in group A. Compared with group A, mice in group E began to suffer from disturbance of consciousness and action ability. With the decrease of core body temperature, the damage was aggravated, and mice in group G died. Compared with group A, the indices of blood routine test (WBC, RBC, HGB, PLT) of mice in group E began to decrease, and the univariate variance calculation showed that only WBC changes had statistical significance ( P<0.05). Compared with groups A and E, the indices of blood routine test (WBC, RBC, HGB, PLT) of mice in group F were further reduced, and the changes of each index in univariate variance calculation were statistically significant ( P<0.05). The general observation results showed that compared with group A, the lung, liver and spleen surfaces of mice in group E began to darken, and compared with groups A and E, the lung, liver, spleen, kidney and heart of mice in group F were further deepened and darkened, with irregular edges. HE staining results of various organs showed that compared with group A, the mice in group E began to have partial alveolar structure destruction and a small amount of inflammatory cell infiltration, the central vein of the liver was slightly congested, and the red and white pulp of the spleen were indistinct. Compared with groups A and E, the pathological structure damage of the lung, liver, spleen, kidney, heart and brain tissues of the mice in group F was further aggravated. Conclusions:Detection of consciousness state, action ability, general state of organs, blood routine and HE staining indices of organs in mice under low temperature can simulate the progress of clinical acute cold injury, and the animal model of acute systemic cold injury was successfully prepared.

Objective To investigate the therapeutic effect of acupoint massage combined with moxibustion on urinary retention after spinal cord injury. Methods A total of 81 cases with urinary retention after spinal cord injury hospitalized in the Second Affiliated Hospital of Heilongjiang University of Chinese Medicine from February 2016 to February 2017 were recruited in the study using random sampling method. Patients were randomly divided into the control group (42 cases) and the intervention group (39 cases). Both groups were given routine rehabilitation therapy and nursing care, and the intervention group received additional acupoint massage combined with moxibustion therapy. The clinical efficacy, the autonomous urination time and the incidence of complications of patients were compared between two groups. Results After the treatment, the clinical efficacy in the intervention group and the control group were 92.3% and 68.2% respectively, with statistically significant difference between two groups (χ2=9.42, P=0.01). The autonomous urination time of patients in the intervention group was (23.10±2.92) d, which was significantly shorter than that in the control group (P<0.001). The number of urinary tract infection cases in the intervention group was lower than that in the control group; there was no statistically significant difference between two groups (P>0.05). Conclusions The application of acupoint massage combined with moxibustion in patients with urinary retention after spinal cord injury has good effects and is worthy of clinical promotion.

Objective To explore the clinical effects of warming needle moxibustion on lower limbs arteriosclerosis obliterans of blood stasis type. Methods From September 2015 to September 2017, we selected 60 patients from the First Affiliated Hospital and the Second Affiliated Hospital, Heilongjiang University of Chinese Medicine. All of the patients were divided into control group and intervention group with the randomized control method, 30 cases in each group. Patients of control group were treated with Huo Xue Tong Mai Yin decoction. Patients of intervention group accepted warming needle moxibustion and Huo Xue Tong Mai Yin decoction. We compared the clinical effects, diameter and blood flow parameters of lower extremity artery, the expression of nitric oxide (NO) and endothelin (ET) between two groups before and after treatment. Results Clinlcal symptoms of patients between two groups all relieved in different degrees. For example, pain eased; the temperature of lower limb got warm again; the dull-red and pale colour weakened; the number of walk and qi-blood increased; the improvements of the symptoms in intervention group were better than those in control group with significant differences (P<0.05). The improvements of diameter and blood flow parameters of lower extremity artery in intervention group were significantly better than those in control group (P< 0.05). After treatment, the expression of NO and ET of intervention group was (39.30±3.10) ng/L and (28.14±3.10) μmol/L respectively better than those of control group with significant differences (t=3.277, 2.716; P< 0.05). Conclusions Warming needle moxibustion has a remarkable clinical effect on lower limbs arteriosclerosis obliterans of blood stasis type. It is worth to be generalized.

BACKGROUND:Genetic studies have shown that there may be association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women, but there are some differences in the conclusions.
OBJECTIVE:To study the association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women through Meta-analysis.
METHODS:The PubMed database, Embase database, CNKI database and Wanfang database were searched for the observational studies about the association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women. The standardized mean difference was considered as the effect indicator and calculated with random or fixed effect models according to the significance of heterogeneity.
RESULTS AND CONCLUSION:A total of 9 articles were included with a total of 8 799 and 9 365 participants for which vertebral and spine bone mineral density had been measured, respectively. The analysis results showed that the bone mineral density of the postmenopausal women with the G al ele of G1181C was significantly lower than that of the postmenopausal women with the C al ele. Similar results were obtained in Caucasian population subgroup analysis. The Caucasian population subgroup analysis showed that the bone mineral density of the postmenopausal women with GG genotype of G1181C was lower than that of the postmenopausal women with GC and CC genotype. The results indicate that there is association between osteoprotegerin gene G1181C polymorphism and bone mineral density in postmenopausal women, and G al ele is a risk factor for lower bone mineral density.

Objective To develop autosomal SNP fluorescent-multiplex PCR system,and investigate the allele frequencies of these 13 SNP loci in Southern Liaoning Han population.Methods After selected 13 autosomal SNP loci,SNP fluorescent-multiplex system was developed based on the principle of fragment length discrepant allele specific PCR,and the allele frequencies of these SNP loci in Southern Liaoning Han population were investigated using the established system.Results For the same SNP locus,the homozygote showed a single product peak,and the heterozygote showed two product peaks with different length.For the different SNP loci,the lengths of their PCR products were different.Therefore,we could genotype the 13 SNP loci simultaneously according to the length of products and the amount of product peaks,and the results were in accordance with that of direct sequencing.In the meanwhile,the allelic frequencies of these 13 SNP loci in Southern Liaoning Han population were obtained.Conclusion The SNP fluorescent-multiplex system based on the fragment length discrepant allele specific PCR strategy is simple and economical,and is of a high application value in forensic medicine.
