This study was aimed to explore rules of classification and quantitative diagnosis of syndromes of as-thenospermia and oligospermatism on the basis of statistical analysis of the multi-factor. Factor analysis was used to analyze clinical symptoms of 507 patients. Scores were given according to the severity of symptoms. Five repre-sentative factors were extracted from the symptoms of asthenospermia and oligospermatism, which are the downward diffusion of damp-heat, kidney essence insufficiency, kidney yang deficiency, liver qi stagnation and kidney yin deficiency. Syndromes were quantized at the same time. Rules of syndrome sorting and quantitative diagnosis which come from large-scale sample provide evidences for clinical diagnosis of asthenospermia and oligospermatism.

Objective To investigate the expressions of microRNA-21,microRNA-143,and microRNA-145 in the sera of patients with nasopharyngeal carcinoma (NPC),and their assessment vales in the recurrence,metastasis,and prognosis of NPC patients.Methods From January 2012 to January 2014,80 NPC patients in our hospital Department of Internal Medicine and Head and Neck Surgery was used as tumor group,80 cases of healthy volunteers as control.The real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the expression levels of microRNA-21,microRNA-143,and microRNA-145 in the sera.Results Expression of microRNA-21 in NPC patients was significantly higher than that in healthy control group with statistically significant difference (P ＜ 0.05).The expressions of microRNA-143 and microRNA-145 in NPC patients was significantly lower than those in healthy control group with significant difference (P ＜ 0.05).At the same time,those microRNAs were significantly associated with tissue differentiation,invasion,and metastasis.Conclusions Increased microRNA-21 expression level in NPC patients,and decreased expression of microRNA-143 and microRNA-145 in NPC patients play an important role in differentiation,invasion,and metastasis in the development process of NPC.microRNAs can be used as a new index in the auxiliary diagnosis of NPC and the evaluation of recurrence,metastasis,and prognosis evaluation.

A total of 258 cases of elderly patients with herpes zoster were divided into treatment group (n =128) and control group (n =130).The treatment group received a once daily dose of narrowband ultraviolet irradiation plus oral acyclovir 0.8 g,5 times a day.However,the control group received a once daily dose of infrared therapy plus the same oral acyclovir.At Day 9,the effective rates of treatment and control groups were 91.7％ (117/128) vs.74.6％ (97/130) (P＜0.05).Also,in terms of pain relief time (2.56 ± 1.51) vs.(5.44 ±4.06) days,crusting time (4.51 ±0.48) vs.(6.11 ± 1.81) days and healing time (5.65 ±0.56) vs.(9.28 ±0.21) days,the treatment group was better than those of the control group (P ＜0.01).

This study was aimed to observe the effect of Bushen-Huoxue-Tonglin formula (BSHXTLF) on Ki-67 and apoptotic bodies in benign prostatic hyperplasia (BPH) rats. A total of 72 Wistar rats were randomly divided into 6 groups, which were the sham operation group, model group, Proscar group (0.8 mg?kg-1), BSHXTLF groups with low, middle and high dose (7.5, 15, 22.5 g?kg-1). Except the sham operation group, the BPH model was established by injecting testosterone propionate (5 mg?kg-1) for 30 days after removing both testicles in the rats. The drugs were administrated once a day for 30 days at the same time. The immunohistochemical and TUNEL methods were used to determine Ki-67 and apoptotic bodies, respectively. The results showed that compared with the model group , the expression of Ki-67 in treatment groups was decreased ( P < 0 . 05 ) . Compared with Proscar group and low-dose BSHXTLF group, the expression of Ki-67 in the middle- and high-dose BSHXTLF group was decreased ( P < 0 . 05 ) . Compared with the middle-dose BSHXTLF group , the expression of Ki-67 in the high-dose BSHXTLF group was decreased ( P < 0 . 05 ) . Compared with the model group , the expression of apoptot-ic bodies in each treatment group was increased ( P < 0 . 05 ) . Compared with Proscar group , low-dose and middle-dose BSHXTLF group, the expression of apoptotic bodies in the high-dose BSHXTLF group was increased (P <0.05). It was concluded that BSHXTLF may decrease the expression of Ki-67 and increase the expression of apoptotic bodies in BPH rats. These results provided objective evidences for clinical treatment of BPH.

Objective To investigate the specific pathogenesis of O-antigen polysaccharide(OPS) which is a subunit component of lipopolysaccharide(LPS) from enteroinvasive Escherichia coli. Methods The OPS was extracted and purified from Escherichia coli O29(enteroinvasive E.coli) strain. Effects of OPS, contrasted with the whole LPS molecule, were observed by in vitro experiments (HeLa cell culture) and in vivo experiments (rabbit ileal loop assay). Results It was revealed that the purified EIEC OPS alone cause cytopathic effect to HeLa cell, and that the OPS caused mucosal hemorrhage, but no fluid accumulation in ileal loop of rabbits. The scanning electron microscope and transmission electron microscope demonstrated the fine structures of cytopathic HeLa cell were damaged. Conclusion Escherichia coli O29 OPS might be one of the factors causing diarrhea and its mechanism was different from endotoxin reaction of LPS. Escherichia coli O29(pathogen) OPS showed a marked serious toxicity as compared with Escherichia coli HB101(nonpathogen) OPS.

This study was aimed to observe the effect of Bu-Shen Huo-Xue Tong-Lin (BSHXTL) formula on gene expression of Caspase-3 in benign prostatic hyperplasia (BPH) rats. A total of 72 rats were randomly divided into the sham operation group, model group, proscar group, low-dose BSHXTL group, middle-dose BSHXTL group and high-dose BSHXTL group. The rat model was established by injecting testosterone propionate for 30 days after removing testis except the sham operation group. The drugs were administered once a day at the same time of the model establishment. Immunohistochemical method was used to measure positive average gray. And RT-PCR was used to measure the gene expression of Caspase-3.The results showed that compared with the model group, the expression of Caspase-3 and mRNA in each treatment groups were increased (P < 0.05). And the high-dose BSHXTL group was higher than the proscar group and low-dose BSHXTL group (P< 0.05). It was concluded that BSHXTL formula may upregulate gene expression of Caspase-3, which may be the mechanism of BPH treatment.

Objective To evaluate the diagnostic value of puncture feeling combined with fine-needle aspiration cytology (FNAC) for thyroid nodules.Methods One thousand and fourteen thyroid nodules were retrospectively analyzed.Eighty-six thyroid nodules were performed repeat FNAC.All nodules were confirmed by pathology,the agreement of puncture feeling at different time was evaluated by Kappa test.Results There were 751 malignant nodules and 263 benign nodules.Sensitivity and accuracy of FNAC combined with puncture feeling were higher than those of single FNAC or single puncture feeling (x2 =11.609,4.433 and P =0.00,0.04;x2 =19.369,6.697 and P =0.00,0.01,respectively).There were no statistically differences in the sensitively and accuracy between single FNAC and puncture feeling (x2 =1.230,0.242 and P =0.27,0.62,respetively).The Kappa values of inter-observer and intra-observer were 0.829(P =0.00) and 0.885(P =0.00) respectively with statistically significance.Conclusions Puncture feeling combined with FNAC can improve the sensitivity and accuracy in the diagnosis of thyroid nodules,the reproducibility of puncture feeling is excellent.

Objective To evaluate the efficacy of sniffing position in alleviating glossoptosis during the emergence from anesthesia in children. Methods Two hundred pediatric patients who developed glos?soptosis during the emergence from anesthesia, aged 2-8 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, were randomly divided into 4 groups ( n=50 each) using a random number table:head extension position group ( group A ) , head tilted position group ( group B ) , oropharyngeal airway group ( group C) and sniffing position group ( group D) . Alleviation of glossoptosis, and occurrence of la?ryngospasm, agitation, vomiting and oral hemorrhage were recorded. Alleviation rate was calculated. Re?sults Compared with group A, the alleviation rate was significantly increased in C and D groups, the alle?viation rate was decreased in group B, and the incidence of laryngospasm, agitation and oral hemorrhage was increased in group C ( P<0?05 ) . Conclusion Sniffing position can effectively alleviate glossoptosis during the emergence from anesthesia in children with good safety.

Objective To evaluate the diagnostic value of TSSC1 in glioma patients and its influence on cell biologi-cal behavior of glioma U87 cells. Methods RT-PCR and Western blot were used to examine the expression of TSSC1 in glioma samples, including 80 normal paraneoplastic tissues and 80 primary tumors. MTT and transwell were used to analyze the effect of TSSC1 knockout on proliferation, migration, and invasion in U87 cells. Results TSSC1 is down-regulated in glioma compared to its paraneoplastic counterparts and negatively related to higher grade. Furthermore, knockdown of TSSC1 expression results in increased proliferation, migration and invasion in U87 cells in vitro. Conclusion Our results may worked as a marker for early diagnosis and prognosis of glioma.

Objective To investigate the scintigraphic features of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) and to explore the clinical significance of 99Tcm-EHIDA hepatobiliary scintigraphy.Methods Hepatobiliary scintigraphy with 99Tcm-EHIDA was performed in 28 genetic confirmed NICCD cases (16 males,12 females,1-8 months).Normal dynamics (i.e.,time-activity curve) of the tracer in heart,liver and kidneys was defined as normal hepatic uptake function.Decreased liver uptake of the tracer and/or prolonged heart and kidneys radioactivity retention was defined as impaired hepatic uptake function.Normal or delayed biliary excretion was defined as radioactivity appearing in the bowel within 60 min or after 60 min.Occluded biliary excretion was defined as absent bowel radioactivity within 24 h.The characteristics of hepatobiliary scintigraphy and their relationship with levels of serum total bilirubin (TB),direct bilirubin(DB),ALT,total bile acid (TBA) were retrospectively analyzed.Statistical analysis was performed using Kruskal-Wallis rank sum test.Results Of 28 NICCD patients,20 showed normal uptake while 8 had impaired hepatic uptake.Ten of twenty patients with normal uptake function showed normal biliary excretion and the others showed delayed biliary excretion.Four of eight cases who presented impaired hepatic uptake function were with delayed biliary and the rest displayed biliary excretion occlusion.Compared with the patients with normal hepatic uptake function,patients with impaired hepatic uptake had significantly higher levels of TB and DB (TB:183.6(128.7-280.9) mmol/L vs 105.5(80.0-141.7) mmol/L,Z=-2.25;DB:135.6 (95.7-212.6) mmol/L vs 73.1(53.9-97.9) mmol/L,Z=-2.73; both P＜0.05).Compared with the cases with normal biliary excretion function,patients with delayed biliary excretion had significantly higher levels of TB,DB and TBA (TB:137.5 (122.0-170.9) mmol/L vs 81.7(65.7-93.5) mmol/L,Z=-3.92;DB:96.5 (81.1-108.0) mrrol/L vs 54.1(45.3-72.6) mmol/L,Z=-3.74; TBA:245.6(183.9-299.2) mmol/L vs 136.0(73.5-163.2) mmol/L,Z=-2.57; all P＜0.05).The levels of TB (262.0(152.1-542.8) mmol/L) and DB (192.7(118.1-407.2) mmol/L; both Z=-2.82; both P＜0.05) were the highest in patients with occluded biliary excretion.Compared with the patients with delayed excretion,the occluded excretion subgroup had significantly higher levels of ALT (71.5 (48.5-144.8) U/L vs 20.0(16.5-27.7) U/L,Z=-2.66,P＜0.05).Conclusion 99Tcm-EHIDA hepatobiliary scintigraphy may evaluate hepatic uptake and excretion function of the NICCD infants.When the hepatic uptake is remarkably decreased,the occluded biliary excretion can be shown.
