ABSTRACT
Objective:To evaluate the clinical efficacy of Xuanfei Huazhuo prescription in the treatment of coronavirus disease-2019 (COVID-19). Method:A total of 40 patients with COVID-19 were selected and treated with Xuanfei Huazhuo prescription. The changes of body temperature, clinical symptoms, computed tomography (CT), blood routine and biochemical indexes were observed before and after treatment. Result:The 40 patients included 15 males and 25 females, with a male to female ratio of 1∶1.7. They were aged between 20-94 years old, with the average age of （43.9±16.3） years old. The course of disease was 8-23 days, with the average of （14±4.4） days. Compared with before administration, the patients' clinical symptoms, such as cough, fever, sputum, diarrhea, loss of appetite and fatigue, were all improved (P<0.05). Before treatment the traditional Chinese medicine (TCM) syndromes of patients were mainly cold dampness lung (57.5%) and cold dampness Lung (42.5%), and the tongue coating was mainly white greasy coating (52.9%). After adjuvant treatment with Xuanfei Huazhuo prescription, the fever removal time was (2.48±2.56) days; white blood cell (WBC), lymphocyte percentage (LYM%), neutrophil percentage (NEUT%), absolute value of lymphocytes (LYM #) indexes of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total bilirubin (TBIL), ratio of glutamic oxaloacetic transaminase to glutamic pyruvic transaminase (AST/ALT) and lactate dehydrogenase (LDH) were basically restored to the normal range (P<0.05) compared with before administration. After adjuvant treatment with Xuanfei Huazhuo prescription, the results of three pharyngeal test virus nucleic acid tests were negative, and the lung CT showed that infected lesions were absorbed and all met the discharge criteria. All 40 patients met the discharge criteria and were all cured and discharged, with a cure rate of 100%. There has been no case of recurrence with a positive result of nucleic acid detection so far. The score of symptom and clinical index of patients after administration was （1.62±1.90）, which was significantly lower than that before administration (7.65±4.08, P<0.05). Conclusion:In the adjuvant treatment of COVID-19, Xuanfei Huazhuo prescription can reduce body temperature, promote the absorption of pulmonary inflammation, and improve clinical symptoms, such as fever and cough.
ABSTRACT
Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.
ABSTRACT
Objective To evaluate the clinical efficacy of endoscopic transnasal palatal nerve block for persistent allergic rhinitis.Methods 123 patients with heavy persistent allergic rhinitis who aged over 17 years old in Longhua central hospital affiliated to Guangdong medical university from October 2013 to February 2015 were divided into observation group and control group.The patients in the observation group(72 cases) were blocked with endoscopic sphenopalatine,the control group (51 cases) treated with medicine.The rhinoconjunctivitis quality of life questionnaire (RQLQ) and VAS were assessed before and after treatment for 6 months,1 year and 2 year survival.Results 106 patients were followed up for 2 years.In observation group,the average score of RQLQ and VAS before treatment were (2.39 ± 0.43),(7.45 ±1.24) respectively;6 months after treatment,the average scores of RQLQ and VAS were (0.82 ± 0.38),(2.47 ± 1.42) respectively;1 years (0.93 ± 0.41) and (2.53 ± 1.54);2 years (1.05 ± 0.47) and (2.67 ± 1.69);the differences were statistically significant (P ＜ 0.05).The control group showed no obvious difference in RQLQ and VAS before and after treatment.Conclusion Endoscopic sphenopalatine nerve block can effectively improve the quality of life of patients with persistent rhinitis allergic,which is safe and effective in the treatment of severe persistent allergic rhinitis.
ABSTRACT
Objective To investigate the use situation of sunscreen agent in the sunblock cosmetics.Methods Statistic analysis was performed in the kinds,frequencies,dosages of sunsereen agents and the mark dosage coincidence in 414 cosmetics from Sep.2004 to Aug.2007.Results Fourteen kinds of sunscreen agents including phenylbenzimidazole sulphonic acid and its potassium,sodium and triethanolamine salts,benzophenone-4,benzophenone-5,benzophenone-3,isopentyl p-methoxycirmamate, 4-methylbenzylidene camphor,ethylhexyl dimethyl PABA,butyl methoxydibenzoylmethane,octocrylene,ethylhexyl methoxycinnamate,ethylhexyl salicylate,ethylhexyl triazone,methylene bis-benzotriazolyl tetramethylbutylphenol,bis- ethylhexyloxyphenol methoxyphenyl triazine were detected in 414 cosmetics.The use frequency of ethylhexyl methoxycinnamate was above 90%,butyl methoxydibenzoylmethane was 30%,benzophenone-3 and ethylhexyl salicylate were 15% and 11% respectively,and others were less than 10%.The rate of exceed standard limit of ethylhexyl methoxycinnamate,octocrylene, ethylhexyl salicylate,4-methylbenzylidene camphor ethylhexyl dimethyl PABA were 0.24%,0.97%,1.21%,0.48% and 0.24% respectively.The mark dosage coincidence rate of 14 kinds of sunscreen agents were from 42.9% to 89.5%.Conclusion The many kinds of sunscreen agents were used in the sunblock cosmetics,so the special attention should be paid to the cosmetics safety.

ABSTRACT
<p><b>OBJECTIVE</b>Matrix metalloproteinase 1 (MMP1) plays an important role in the development of lung cancer. This study was to investigate the relation to associate the single nucleotide polymorphism(SNP)in MMP1 gene with the susceptibility to lung cancer in Northwestern Chinese population of Han nationality.</p><p><b>METHODS</b>By using the methods of polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP), MMP1 -1607(1G>2G) polymorphisms in 150 patients with lung cancer, and 200 healthy controls were detected to evaluate the relationship between different genotypes and susceptibility of lung cancer.</p><p><b>RESULTS</b>Individuals with 2G/2G genotype had 1.77 fold risk suffering from lung cancer, when compared with ones with 1G/2G and 1G/1G genotypes. Smokers with 2G/2G genotype exhibited 3.20 fold elevated risk for lung cancer (OR 3.20; 95% CI 1.50-6.82).</p><p><b>CONCLUSION</b>The -1607(1G>2G) in promoter region of MMP1 is associated with susceptibility to lung cancer in Northwestern Chinese population of Han nationality. The genotype 2G/2G enhances the susceptibility to lung cancer.</p>
