To evaluate the efficacy of Yupingfeng droppill and western medicine in treatment of allergic rhinitis, 76 patients from Beijing Shijitan hospital during April 2011 to May 2012 were selected and randomly divided into the treatment group (n = 44) and control group (n = 32). The treatment group was treated with Yupingfeng droppill and cetirizine tablets, the control group was treated with cetirizine tablets, the effect of the two groups was observed after 28 days, after treatment, the symptoms and inferior turbinate volume contrast of the two groups were better than before. The obvious effective rate and total effective rate were 84.09%, 95.45% and 46.87%, 56.25% in the treatment group and and control group. The differences in the obvious effective rate and total effective rate were statistically significant between two groups (P < 0.05), Yupingfeng droppill has the curative effect on allergic rhinitis, which is better than simple oral cetirizine tablets.

OBJECTIVEExpress and purify four single-stranded DNA-binding (SSB) proteins, and evaluate the binding of SSB proteins on HCV RNA.

METHODSThe expression plasmids of four SSB proteins were conducted, termed TTH, SSOB, KOD and BL21, respectively. The BL21 (DE3) was transformed by the expression plasmid of TTH, Transetta (DE3) were transformed by the expression plasmid of SSOB, KOD and BL21, then protein expression was induced with IPTG, the expression products were analysised by SDS-PAGE. To evaluate the binding of SSB on HCV RNA, RNA-SSB protein complexes were applied to a 1.2% TAE agarose gel.

RESULTSSuitable competent cells were transformed with the expression plasmids, induced by IPTG. SSB proteins were purified by affinity chromatography, to visualize their purity all SSB proteins were applied to SDS-PAGE analysis. All four proteins showed single clear bands. We have successfully obtained the SSB protein expression plasmid, expressed and purified SSB protein. TAE agarose gel electrophoresis was used to confirm SSB protein-RNA binding activity. The each of SSB-RNA complex migrated more slowly than the sole RNA, which suggested SSB protein could specifically bind to RNA.

CONCLUSIONSWe have expressed and purified four SSB proteins, and for the first time found that SSB protein can bind HCV RNA. Our results may provide a basis for future studies of the novel functions of SSB proteins on RNA.

Objective To study the clinical and pathologic features,histological criteria and pathologic factors contributing to diagnosis of mixed epithelial and mesenchymal tumors(mixed m?llerian tumors,MMT)of the uterus.Methods A retrospective study of 102 cases of MMT of the uterus (74 adenofibromas including 9 recurrent cases,3 atypical polypoid adenomyomas,2 carcinofibromas,10 adenosareomas and 13 carcinosarcomas)was undertaken.Clinical records,gross features and tissue slices were reviewed.The follow-up data were analysed.Results The most common symptom was vaginal bleeding.Clinical signs included pelvic mass,uterine polyps,and enlarged uterus.Benign MMT usually presented as exophytic polypoid masses extending into the uterine cavity or protruding through the external os,often broad-based,lobulated and papillary.It was hard to distinguish low-grade malignant MMT from the benign ones by gross appearance.High-grade malignant MMT had the common gross features of carcinoma and sarcoma.Histologically,MMT showed a biphasic differentiation of mesenchymal and epithelial components.MMT were classified according to whether these elements were benign or malignant.Nine cases of adenofibroma without unique features for the diagnosis of adenosarcoma recurred at postoperative intervals of 3 to 96 months.Recurrent tumors were almost always confined to the original site.Conclusions Uterine MMT tumors according to WHO diagnostic criteria are not rare.The differential diagnosis depends on a multifactorial analysis.The recurrent adenofibromas may be a kind of borderline tumors with benign appearances and malignant behavior.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

OBJECTIVETo explore the scavenging action of tenuigenin (TEN) on intracerebral amyloid β protein (Aβ) aggregation and the abnormal phosphorylated tau protein and its mechanism in Alzheimer's disease (AD) rats' brain.

METHODSAβ1-40 was injected into the right CA1 region hippocampus to establish the AD model. Successfully modeled rats were divided into the model group, the low, middle, high TEN group. Rats were administered with TEN (18.5, 37.0, 74.0 mg/kg) by gastrogavage. Besides, a sham-operation group was set up. Expression levels of Aβ1-40 and Tau p-Ser262 were detected by immunohistochemistry. Expression levels of ubiquitin (Ub) and Ub-protein ligase E3 were measured by Western blotting.The content of 26S proteasome was detected by ELISA.

RESULTSImmunohistochemical results showed that the number of Aβ and Tau p-Ser262 positively reacted neurons significantly increased in model group, when compared with the sham-operation group (P < 0.01). Results of Western blot showed expression levels of ubiquitinated protein were up-regulated and those of Ub-protein ligase E3 were down-regulated in the model group (P < 0.01). ELISA results showed that the content of 26S proteasome significantly decreased in AD rats' brain (P < 0.01). Compared with the model group, expression levels of Aβ1-40, Tau p-Ser262, and Ub significantly decreased; expression levels of Ub-protein ligase E3 apparently increased; the content of 26S proteasome significantly increased in each TEN treatment group (P < 0.05, P < 0.01). Best effect was shown in 37.0 mg/kg and 74.0 mg/kg TEN groups.

CONCLUSIONSUb proteasome pathway (UPP) participated in the occurrence of AD. TEN could obviously reduce intracere- bral Aβ1-40 accumulation and abnormal tau phosphorylation.

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.

RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).

CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

Objective To study the role of hematopoietic growth factor(HGF)of placenta chorionic villus in fetal hematopoiesis during embryo ontogeny by observation of the appearance time and the content changes with the fetal growth, which was compared with HGF in cord blood. Methods Thirty embryo villus (2 g each) and 30 cord blood (2 mL each) were collected separately from early pregnant stage(6- 8 weeks), middle pregnant stage(16-22 weeks)and late pregnant stage (37-42 weeks). The levels of HGF were detected by enzyme - linked immunosorbent assay. Results HGF were produced on the early pregnant stage and the content of FL-T3,IL-3 increased gradually.There were significantly differences at different stages(P

Purpose To investigate the clinicopathological and immunohistochemical features of primary small cell carcinoma of the cervix ( SCCC) and its prognosis. Methods 18 cases of primary cervical small cell carcinoma were evaluated by histopathology, in si-tu hybridization and immunohistochemistry and relevant literatures were reviewed. Results The age of the patients ranged from 30 to 69 years ( mean age, 40 years) . Major clinical manifestation was irregular colporrhagia. Colposcopy often revealed a cervical mass or cervical erosion. Microscopically, the tumor cells were small and round and arranged in a solid distribution. The cell had little cyto-plasm and increased karyoplasmic ratio with deeply stained granular chromatin and increased pathological mitosis. Immunohistochemi-cally, the tumor cells were often positive for CKpan, variable positive for Syn, NES, CgA, CD56 and p16. HPV 16/18 were positive in 4 cases. Conclusion SCCC is a neuroendocrine tumor of high malignancy and poor prognosis with a possible pathogenesis of HPV 16/18 infection. CKpan, Syn, CgA, NSE and CD56 are useful markers for the diagnosis of SCCC.
