Objective To investigate the clinical efficacy of Dahuang Xiaozhi Suppository combined with tetracycline in treating type Ⅲ prostatitis infected with nano-bacteria. Methods Totally 120 patients of type Ⅲprostatitis infected with nano-bacteria were randomly divided into treatment group and control group, with 60 cases in each group. Both groups were disabled anti-infective drugs and other preparations for diet and life intervention. Both groups received tetracycline, once a tablet, twice a day, orally. The treatment group received Dahuang Xiaozhi Suppository, once a capsule, once a day, placing in the anus 3-4 cm. 10 d was a treatment course, for 3 courses. The clinical efficacy, major symptoms improving time, NIH-CPSI, leukocyte count and ecithin corpuscles in expressed prostatic secretion (EPS), urinary flow rate, and cytokine content of TNF-α, IL-6, IL-8, were evaluated. Results The total effective rate was 100.0% (60/60) in treatment group and 83.3% (50/60) in the control group, and treatment group was higher than the control group (P<0.05). Pelvic pain, urinary symptom, and scrotum wet improvement time of treatment group were lower than the control group (P<0.05). Compared with before the treatment, the NIH-CPSI pain scores, urinary symptom scores, life quality score, leukocyte count and TNF-α, IL-6, IL-8 content of EPS in both groups were significantly lower after treatment (P<0.05), and the cases with lecithin corpuscles +++ - ++++ in both groups significantly increased after treatment (P<0.05). The urinary peak flow rate and mean flow rate in both groups were higher after treatment (P<0.05). There was statistical significance in the scores of NIH-CPSI pain, urinary symptom and life quality, leukocyte count and TNF-α, IL-6, IL-8 content of EPS, and the cases with lecithin corpuscles ++++ between the two groups (P<0.05). Conclusion Dahuang Xiaozhi Suppository can improve the efficacy of treating type Ⅲ prostatitis infected with nano-bacteria. Combining Dahuang Xiaozhi Suppository with tetracycline can reduce prostate inflammation, with obvious efficacy.

Objective To investigate the clinical efficacy of Dahuang Xiaozhi Suppository in treating chronic abacterial prostatitis/chronic pelvic pain syndrome (CABP/CPPS) of moist heat and blood stasis syndrome. Methods Two hundred patients of CABP/CPPS were randomly divided into control group and observation group, 100 cases in each group. 2 groups were disabled anti-infective meidicne and other preparations, and received diet and life intervention. The control group received the treatment of Qianliean Suppository, and the observation group received the treatment of Dahuang Xiaozhi Suppository, one capsule each time, once a day, into the anus depth of about 3–4 cm. Ten days were a treatment course with two day interval between each course of treatment. The treatment lasted for three courses. The clinical efficacy of the two groups was observed and compared. The indexes including the scores of NIH-CPSI, leukocyte count and lecithin corpuscles in prostatic fluid, and urinary flow rate were evaluated. Results The total effective rate was 100% (100/100) in the observation group and 78% (78/100) in the control group, and the observation group was much higher than control group (P<0.05). The scores of NIH-CPSI and leukocyte count in both groups were significantly lower after treatment (P<0.01), and those in observation group weresignificantly lower than those in control group (P<0.01). The cases with lecithin corpuscles++++in both groups were significantly more after treatment (P<0.01), and those in observation group were significantly more than those in control group (P<0.01). The peak flow rate and mean flow rate in both groups were higher after treatment (P<0.01), and it was higher in observation group (P<0.01). Conclusion The efficacy of Dahuang Xiaozhi Suppository in treating CABP/CPPS of moist heat and blood stasis syndrome is remarkable, and it is better than Qianliean Suppository.

Objective To investigate the effect of Lumbricus protein on the phenotypic transformation of corporal cavernosum smooth muscle cells(CCSMC)and erectile function in diabetic erectile dysfunction(DMED)rats.Methods Sixty male SD rats with normal erectile function were randomly divided into a blank group,a model group,a Sildelafil group(5 mg·kg-1),and a Lumbricus protein low-,medium-,and high-dose group(45,90,and 180 mg·kg-1),with 10 rats in each group.The diabetic rat model was established by intraperitoneal injection of Streptozotocin(STZ,50 mg·kg-1)combined with high-fat feed feeding;after 8 weeks,the DMED rat model was prepared by neck injection of Apomorphine(APO,100 μg·kg-1).After successful modeling,the rats were administered with a dose of Apomorphine by gavage once a day for 4 weeks.The blood glucose levels and body mass of rats in each group were measured before modeling,on the third day of modeling,and after 4 weeks of drug administration.The intracavernous pressure(ICP)and carotid artery pressure(MAP)were measured by multi-channel physiological recorder,and the ICP/MAP ratio was calculated.The expressions of contractile markers α-smooth muscle actin(α-SMA),smooth muscle myosin heavy chain(SMMHC)and synthetic markers Collagen I and osteopontin(OPN)in corpus cavernosum were detected by immunohistochemistry.The mRNA expression levels of α-SMA,SMMHC and Collagen I in corpus cavernosum were detected by RT-PCR.The protein expression levels of α-SMA,Desmin,Collagen I and OPN in corpus cavernosum were detected by Western Blot.Results Compared with the blank group,the blood glucose levels of the rats in the model group were significantly increased on the third day of modeling and after 4 weeks of administration(P＜0.01),and the body mass was significantly decreased after 4 weeks of administration(P＜0.01).ICP and ICP/MAP ratio were significantly decreased(P＜0.01).The protein expression levels of α-SMA,SMMHC and Desmin in penile corpus cavernosum were significantly decreased(P＜0.01),and the protein expression levels of Collagen I and OPN were significantly increased(P＜0.01).The mRNA expression levels of α-SMA and SMMHC in corpus cavernosum were significantly decreased(P＜0.01),and the mRNA expression level of Collagen I was significantly increased(P＜0.01).Compared with the model group,there was no significant change in blood glucose and body mass of rats in the administration group(P＞0.05).ICP and ICP/MAP ratio were significantly increased(P＜0.01).The expression levels of α-SMA,SMMHC and Desmin in corpus cavernosum were significantly increased(P＜0.01),while the expression levels of Collagen I and OPN were significantly decreased(P＜0.01).The mRNA expression levels of α-SMA and SMMHC in corpus cavernosum were significantly increased(P＜0.01),and the mRNA expression level of Collagen I was significantly decreased(P＜0.01).Conclusion Lumbricus protein can improve the erectile function of DMED rats,and its mechanism may be related to the inhibition of CCSMC from'contractile'to'synthetic(proliferative)'transformation.

Objective:To understand the oral health status of urban and rural residents in China,the Fourth National Oral Health Epidemiological Survey (FNOHES) was conducted in 2015.Materials and methods:Based on the principles of multi-stage,stratified,equal capacity,and random sampling,the subjects included five groups of residents aged 3-5,12-15,35-44,55-64,and 65-74 years in all 31 provinces,municipalities,and autonomous regions except Hong Kong,Macao,and Taiwan.The total sample size was 172,425.The survey covered two areas,namely oral health status and knowledge,attitude and oral health behavior.Results:Residents in China had serious caries and poor periodontal condition.The prevalence of caries was above 50％ in all age groups,subjects without periodontal disease accounted for ＜50％,and fewer than 50％ of subjects brushed their teeth twice a day.Based on the results of the FNOHES,the following suggestions were proposed for improving the oral health in China in the future:to establish and improve the comprehensive prevention and control system for oral diseases,implement a comprehensive prevention and control strategy for priority groups,strengthen the oral health education for all people to improve oral health literacy,enhance dynamic monitoring to scientifically evaluate oral health status,and coordinate multi-party resources to establish and improve the oral health service security system.Conclusion:The oral health status of Chinese residents and their oral health behavior habits need to be improved.With the support of the administrative departments of the government and unremitting efforts of the oral health staff,all sectors of society must be coordinated to strengthen oral health education for the whole population.Furthermore,comprehensive prevention and control measures must be implemented for priority groups.

OBJECTIVETo study the relationship between polymorphism of inducible Nitric Oxide Synthase (iNOS) gene and the susceptibility of intestinal type stomach cancer and stomach cardia cancer in Chinese people.

METHODSA community-based case-control study was designed. Ninety-three intestinal type of stomach cancer and 50 stomach cardia cancer patients with endoscopy and pathology diagnosis were identified as cases. Two hundred and forty-six controls served as controls.

RESULTSC-->T polymorphism was found in exon 16 of iNOS gene, which changed the coding amino acid from serine to leucine, and formed a recognition site identified by Tsp 509 I restriction enzyme (we called it C-->T polymorphism). The T allele gene frequency in the control group was 13.21%. No statistically significant difference was found between C-->T polymorphism alone and the increased susceptibility to intestinal stomach cancer or stomach cardia cancer. A significant type 2 multiplicative interaction was found in increasing both the risk of intestinal stomach cancer and stomach cardia cancer when both C-->T polymorphism and tobacco smoking exposure existed. An additive interaction model, which showed statistically significant difference, was found to increase only the risk of stomach cardia cancer when CagA antibody shared negative but C-->T polymorphism occurred.

CONCLUSIONC-->T polymorphism of iNOS gene was considered as one of the possible susceptible genes, which specifically increased the risk of tobacco-related but CagA negative types of intestinal stomach cancer and stomach cardia cancer.

OBJECTIVETo find out the distributive features of some metabolic genes polymorphisms in Han population of south area of China.

METHODSStudy population was obtained from the controls of a community based case-control study, which included 290 blood relatives (inner control) and 404 non-blood relatives (outer control).

RESULTSFrequencies of CYP1A1, GSTM1 and GSTT1 polymorphisms had no significant difference among confounding factors, such as sex, living areas, stomach cancer family history and history of tobacco smoking etc. Some controls showed significant difference in age group and alcohol drinking which would be adjusted in analysis of the relationship between polymorphisms and cancers. CYP1A1 Ile/Val and Val/Val genotypes were 33.43% and 5.62% respectively, which were similar to other results from Chinese and Japanese, but higher than those from Caucasians in American, Europe and African-Americans. GSTM1 null allele frequency was 53.48% in our population, which showed difference even among Chinese in different areas. GSTT1 null allele frequency was 45.78%, which was significantly higher than that in Caucasians and African-American.

CONCLUSIONThe frequencies of CYP1A1 Ile/Val, Val/Val and GSTT1 null in Han population in south area of China are significantly higher than those in other races, while the ethnic difference of frequency of GSTM1 null is less.
