Clinical Research on Treatment of Benign Prostatic Hyperplasia with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Benign prostatic hyperplasia （BPH）， a common disease in urology and andrology， is mainly manifested as enlarged prostate glands， bladder outlet obstruction， and lower urinary tract symptoms（LUTS）， which seriously affects the quality of life of middle-aged and elderly men. This disease falls into the categories of "retention of urine" and "prostatic hypertrophy" in traditional Chinese medicine （TCM）. In recent years，many doctors have put forward their understandings of BPH based on academic classics and their clinical experience. Clinical research on the treatment of BPH with TCM has become increasingly abundant. The basic pathogenesis of BPH lies in the disturbance of Qi transformation in the bladder and poor blood circulation due to kidney Qi deficiency in the aged. The disease is located in the kidney and the bladder and is related to the dysfunction of the lung and the kidney. It is basically characterized by deficiency in origin and excess in superficiality. A large number of clinical research reports have proved that TCM is efficient in alleviating the clinical symptoms of BPH patients， improving their quality of life， reducing the volume of the prostate， and decreasing postoperative complications. In addition， the external treatment methods of TCM， such as acupuncture therapy， moxibustion， hot water bathing， acupoint application， anal suppository， and enema therapy， are also widely used in clinical practice， demonstrating the diverse ways of TCM in treating BPH. TCM and western medicine complement each other's advantages in the treatment of BPH， thus enhancing the clinical efficacy and reducing the occurrence of long-term complications. This study reviewed the etiology， pathogenesis， and treatment progress of BPH with TCM in recent years， and summarized the current research status. From three aspects of producing high-quality clinical research， standardizing the clinical diagnosis and treatment of TCM， and combining cutting-edge research to explore the mechanism of TCM， it provided suggestions for clinical research on the treatment of BPH with TCM to promote the development and application of TCM in the treatment of this disease.

Genetic polymorphism and antibody screening of RhD negative Chinese Han population in Jiayuguan / 中国输血杂志

【Objective】 To investigate and analyze the polymorphism of RHD gene in RhD-negative population in Jiayuguan using molecular biological technique, so as to accurately identify RhD-negative individuals, and formulate individualized transfusion strategies. 【Methods】 The RhD negative voluntary blood donors and patients (mainly pregnant women) were recruited. After informed consent, history of blood transfusion and pregnancy of them were investigated, and samples were collected for negative D confirmation, gene sequencing as well as antibody screening and identification. 【Results】 Among the 96 samples, 73 cases were RHD gene deletion, 18 RHD*01EL.01(17 RHD1227A homozygous type and 1 RHD1227A heterozygous type), 2 weak RHD*15 type (845G/A), 1 partial D type, i. e. RHD-CE(7) -D heterozygous allele, and 2 RHD*01N.16 variant. Antibody was detected out in 4 cases, among which 2 were positive for anti-D, 1 anti-D plus anti-E, and 1 anti-Dia. 【Conclusion】 The proportion of DEL gene in RhD negative Chinese Han population in Jiayuguan is slightly lower than that in general Chinese Han population. No anti-D or RHD-HDN was observed in DEL type women due to multiple pregnancy or delivery of D positive newborns.

Erectile dysfunction and psychological status in infertile males / 中华男科学杂志

Objective@#To investigate the relationship of erectile dysfunction (ED) with psychological factors in male patients with infertility.@*METHODS@#We conducted a questionnaire investigation among 252 male patients with infertility, which involved the general condition, results of semen routine examination, sexual life, and scores in IIEF-5, self-reported 9-item patient health questionnaire (PHQ-9) and 7-item generalized anxiety disorder scale (GAD-7). We analyzed the prevalence of ED, depression, and anxiety and their correlations among the patients in comparison with 100 fertile male controls.@*RESULTS@#In 245 of the infertility patients, the most common symptoms of depression and anxiety were "feeling tired or no vitality" and "easily getting worried or impatient", 20.4% of them with depression disorder and 42.9% with anxiety disorder. The PHQ-9 and GAD-7 scores were significantly higher in the infertile males than in the normal fertile controls (P <0.05), and so was the incidence of ED (28.6% vs 12.4%, P <0.05), while the IIEF-5 scores were markedly lower in the former than in the latter group (P <0.01), and so were sex frequency and sexual satisfaction (P <0.05). The PHQ-9 and GAD-7 scores were remarkably higher in the infertility patients with ED than in those without (P <0.01). Logistic regression analysis showed that the level of libido and results of semen routine examination were the risk factors for depression disorder, while age, education level, disease course and experience of assisted reproduction were those for anxiety disorder.@*CONCLUSIONS@#Male infertility patients have a poorer mental health and a higher incidence of ED than normal fertile men, and there is some interaction between psychological status and ED prevalence.

Unsupervised data mining for prescription and medication regularity for treatment of cervical vertigo / 中国中药杂志

Vertebral artery type cervical spondylosis is a common type of cervical spondylosis, also known as cervical vertigo. In recent years, with the increase of people's life pace and the number of office staff, the incidence rate has been rising year by year, with a trend of younger age. Because traditional Chinese medicine has unique advantages in treating cervical vertigo, it is necessary to study the regularity of the Chinese medicine for cervical vertigo. But at present, the research is mainly based on the statistics for frequency and proportion of herbs. In addition, in the process of diagnosis and treatment of Chinese medicine, personal experience also caused differences in prescription compatibility and drug dosage, which makes difficult guarantee for the safety and effectiveness of drug treatment. So, this paper is based on literatures about the traditional Chinese medicine in treatment of cervical vertigo in the past 5 years, by using association rules algorithm, complex system entropy clustering and other non supervised data mining methods. Analysis was made for the use of various drugs in the frequency, the association rules, the core drug combination and the new prescriptions. The traditional Chinese medicine inheritance support system(TCMISS) was utilized to analyze 154 drugs from the 101 prescriptions, determine the use frequency of drugs, analyze the characteristics and the compatibility of core drugs, and dig out 14 core drug combinations and 7 new prescription combinations. The prescription and medication regularities illustrates the drugs for treatment of cervical vertigo, including those for flating liver and suppressing yang, invigorating the circulation of blood to remove blood stasis, reducing water and permeating dampness, increasing qi and activating blood, and nourishing the liver and kidney mainly. Treatment rules are nourishing liver and kidney, invigorating the circulation of blood stasis Tongqiao, reducing phlegm and dampness, flating liver and suppressing yan, dredging collaterals, supplementing qi and nourishing blood. This study aims to summarize frequently used single herbs for vertebral artery type cervical spondylosis, combinations of frequently used herbs and dosage of frequently used herbs with significant efficacy, define the current prescription and medication regularities for treating cervical vertigo and give guidances for clinical mediation.

The expression of P-selectin in rats with hepatic ischemia reperfusion injury / 中国基层医药

Objective To explore the express of P-selectin in liver-tissue,on the model of HIRI in rats,we explored the pathogenesy of HIRI. Methods 32 female Sprague-Dawley rats were divided into four groups randomly ( n = 8 in each group): sham operation group ( group SO ), ischemia 30 min without repe- rfusion group ( group Ⅰ),30 min reperfusion following ischemia 30 min group ( group IR30 min), one hour reperfusion following ischemia 30min group( group IR1h). The model of HIRI was maded by Pringle's hepatic vascular occlusion. The contents of P-selectin in hepatic tissue were measured by kit of SP. Results After ischemia 30 min,the content of P-selectin in hepatic tissue increased less obviously than group SO; After 1 h reperfusion, the content of P-selectin in hepatic tissue vascular endothelial and hepatocyte express more broadly than group SO. Conclusion The content of P-selectin in hepatic tissue was increased gradually in the process of hepatic ischemia reperfusion injury(HIRI) in rats.
