Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

Objective To observe the clinical efficacy of stage-based treatment of peripheral facial paralysis with Yifeng (TE 17) selected as the major point treated by different acupuncture methods.Method A total of 102 patients with peripheral facial paralysis were randomized into a treatment group and a control group, 51 cases each. The treatment group was intervened by selecting Yifeng (TE 17) as the major point, treated with centro-square needling in the acute stage, triple needling in the resting stage, and proximal needling in the remission stage; the control group was intervened by ordinary acupuncture. The two groups were treated once a day, 5 d as a course of treatment. Before and after 3 treatment courses, the House Brackmann (HB) facial nerve grading scale and Visual Analogue Scale (VAS) in those patients complicated with pain were observed, and the clinical efficacies were compared.Result The total effective rate and recovery rate were respectively 100.0％ and 82.3％ in the treatment group versus 86.3％ and 60.8％ in the control group, and the between-group differences were statistically significant (P<0.05). The HB scores were significantly changed respectively after 1, 2 and 3 treatment courses in the two groups compared with the pre-treatment scores (P<0.05). The HB scores in the treatment group were significantly different from those in the control group respectively after 1, 2 and 3 treatment courses (P<0.05). The patients complicated with facial pain or headache presented significant differences in VAS score respectively after 1, 2 and 3 treatment courses in the two groups (P<0.05). In comparing the VAS score in the patients complicated with facial pain or headache, there were significant differences between the two groups respectively after 1, 2 and 3 treatment courses (P<0.05).Conclusion Stage- based treatment with Yifeng (TE 17) selected as the major point treated with different acupuncture methods can produce valid efficacy in treating peripheral facial paralysis.

Objective To investigate the clinical efficacy of staging treatment with various acupuncture therapies mainly on Yifeng (TE17) point for the treatment of peripheral facial paralysis. Methods One hundred and two peripheral facial paralysis patients were randomly divided into trial group and control group, 51 patients in each group. The trial group was given acupuncture mainly on Yifeng point, by Yang needling(plum-blossom needling) for acute stage, Qi needling(concentrated triple-needling) for resting stage and Bang needling(lateral needling) for recovery stage. The control group was given conventional acupuncture. The treatment for the two groups was performed once a day, 5 continuous days constituted a course, and the treatment lasted 3 courses. Before treatment and after treatment for 1, 2, 3 course (s), facial nerve function scores were evaluated with House-Brackmann Grading Scale (HB) and the scores of pain in head and face were evaluated with Visual Analogue Scale (VAS). And the clinical efficacy of the two groups was assessed after treatment. Results (1) After treatment for 3 courses, the cure rate and total effective rate of the trial group were 82.35％, 100.00％, and those of the control group were 60.78％, 86.27％, respectively. The differences between the two groups were significant (P <0.05). (2) After treatment, HB scores and VSA scores of patients with facial pain and headache in the two groups were improved after treatment (P < 0.05 compared with those before treatment), and the improvement in the trial group was superior to that in the control group (P < 0.05). Conclusion Staging treatment with various acupuncture therapies mainly on Yifeng point is more effective for the treatment of peripheral facial paralysis than conventional acupuncture.

BACKGROUNDThe benefits and safety of sirolimus-eluting stent (SES) have not been systematically quantified in different trials in ST-segment elevation myocardial infarction (STEMI) patients with primary or rescue percutaneous coronary intervention (PCI). A meta-analysis of randomised trials comparing SES and bare-metal stent (BMS) was performed.

METHODSA systematic literature search was conducted to identify all randomized clinical trials. The primary outcome was the rate of major adverse cardiac events (MACEs). The secondary outcomes included death, recurrent myocardial infarction, recurrent revascularization, and stent thrombosis.

RESULTSTotally, 1973 STEMI patients were enrolled in seven eligible randomized trials comparing SES with BMS. The pooled rate of major adverse cardiac events was significantly lower in the SES group than in the BMS group (9.7% vs 20.3%, OR 2.45, 95% CI 1.88-3.19, P < 0.00001). No significant difference in all causes of death was found between the SES and BMS groups, as well as in the pooled recurrent myocardial infarction rates. The pooled recurrent revascularization rate was significantly lower in the SES group than in the BMS group (5.1% vs 14.8%, OR 3.30, 95% CI 2.37-4.60, P < 0.00001). No significant difference was found between the pooled rates of stent thrombosis (1.2% in the SES group and 2.0% in the BMS group, OR 1.61, 95% CI 0.79-3.26, P = 0.19).

CONCLUSIONSSES is associated with a decreased risk of major adverse cardiac events compared with BMS by the greater reduction in repeat revascularization in STEMI patients. Larger trials with longer follow up are warranted to better define the role of SES in STEMI.

OBJECTIVETo study the effect of DPC4 gene expression on the growth of colon cancer cells and its mechanism.

METHODSExpression plasmid pcDNA3.1-DPC4 was constructed and transfected into the colon cancer cell line SW620 by use of lipofectamine gene transfer technique. DPC4 protein expression was detected by Western blot and immunocytochemistry. The effect of DPC4 gene on the growth of SW620 cells was monitored by population doubling time (PDT) and cloning efficiency. The influence of DPC4 expression on p21WAF1 transcription was investigated by RT-PCR to detect p21WAF1 mRNA.

RESULTSSuccessful expression of DPC4 protein was detected in the transfected SW620 cells. Compared with the control cells, PDT (74 h) of the DPC4 expressing cells was prolonged and the cloning efficiency (21%) decreased. In addition, the mRNA level of p21(WAF1) in DPC4 transfected cells was increased.

CONCLUSIONSOverexpression of DPC4 gene inhibits the growth of colon cancer in vitro, and induction of p21(WAF1) expression may be an important functional aspect of DPC4.

BACKGROUNDThe efficacy and safety evidence of bortezomib in multiple myeloma (MM) patients with hepatitis B is vacant. This study aimed to investigate the efficacy and safety of bortezomib in MM patients with hepatitis B in China.

METHODSFrom 2006 to 2011, 739 newly diagnosed MM patients were screened for serum hepatitis B virus (HBV) biomarkers. HBV-infected patients were followed for HBV reactivation by monitoring of serum alanine transaminase (ALT) and HBV DNA load. The pattern of HBV reactivation in relation to bortezomib was evaluated. Seven hundred thirty-nine MM patients were included in this study.

RESULTSThe prevalence of MM patients infected with HBV was 3.4% (n = 25), of which 17 cases were treated with bortezomib. Bortezomib had no significant influence on liver function (ALT before and after treatment: 36.69 ± 8.90 U/L vs. 11.31 ± 2.74 U/L, P = 0.19) and HBV DNA of MM patients with HBV (detectable HBV DNA percentage: 5.9% vs. 11.8%, P = 0.12).

CONCLUSIONSBortezomib can be used safely and effectively in MM patients with hepatitis B. HBV prophylaxis and surveillance are recommended during the MM treatment.

OBJECTIVEThis study is aimed to observe the natural draining state of maxillary sinus, to search for the key draining location (KDL) in the natural ostium, to investigate the relation between maxillary sinus draining and sinus inflammation, and to guide the treatment of maxillary sinus opening in endoscopic sinus surgery (ESS).

METHODSMethylene blue was used as tracer agent in this study. Fifteen cases with or without light maxillary sinus inflammation (without any treatment) were selected to observe the natural draining state and the key draining location in maxillary sinus fontanel. Eighty-nine cases with chronic rhinosinusitis, but without nasal polyp, were selected, of which the maxillary sinus mucosa restored well 6 months after ESS, to observe the draining state and modes in maxillary sinus. All patients were followed up for 12 months to evaluate the inflammation state of mucosa, and to analyze the relations between the draining mode and mucosa inflammation.

RESULTSThe KDL for maxillary sinus was located in the posterior-inferior portion of the natural ostium, close to the attachment of caudal end of the uncinate process. The draining flowed along it from maxillary sinus to nasopharynx. After conventional transnasal endoscopic operation, 15 cases showed relatively normal drainage, others displayed abnormal state and mode,including reverse draining (maxillary sinus-ethmoid sinus) , multiphase draining (outflow from front, back and lower wall of natural ostium), draining failure (with cilia transporting function of maxillary epithelium mucosae), cistern like change (maxillary sinus and ethmoid sinus formed one operation cavity, secretion accumulated in maxillary sinus) and mucosa disfunction (loss of cilia transporting function of maxillary epithelium mucosae). Inflammation was observed in 33.7% of the patients 12 months after ESS, especially in those with mucosa disfunction, draining failure and reverse draining.

CONCLUSIONSThe KDL for maxillary sinus may be located in the posterior-inferior portion of the natural ostium, close to the attachment of caudal end of the uncinate process, and the drainage mode is not affected by gravity and posture. The KDL lesion after ESS results in abnormal draining of maxillary sinus, and excessively large maxillary sinus opening may aggravate mucosa inflammation of maxillary sinus. The abnormal draining state and mode may be related with the incidence of mucosa inflammation after operation. Preserving caudal end of uncinate process and avoiding injury of KDL would be beneficial to the restoration of mucosa and lessen the incidence of inflammation recurrence.

OBJECTIVETo study molecular epidemiology of norovirus (NV) infections, stool specimens collected from children with acute diarrhea were tested by TaqMan real-time reverse transcription polymerase chain reaction (RT-PCR) for the viral specific nucleic acid segments.

METHODSFecal samples from a total of 1260 children who had watery diarrhea seen from December 2006 to December 2007 in Guangzhou were analyzed by real-time RT-PCR. The primers and probes used for rapid detection and typing of NV strain target NV sequences were at the ORF1-ORF2 junction, a highly conserved region of the NoV genome. The positive specimens were determined by nested PCR and sequenced.

RESULTSTotally 257 specimens were positive for NV with a positive rate of 20.40%. Shedding of NV type GI was detected in 6.90%, type GII in 16.98% respectively, while the positive number of mixed infection with GI and GII was 44. Of the NV strains that were cloned and sequenced, GI was GI-3, GI-2 and GI-4 detected in positive specimens respectively; meanwhile, GII-4 was most commonly seen in genome II, followed by GII-3 and GII-7. In addition, the average age of children infected with NV was less than 2 years. An epidemic occurred during the winter and early spring (December through the next March).

CONCLUSIONNV was one of the important pathogens for acute diarrhea among children in Guangzhou, which suggested GII-4 was the prevalent strain.

Bletilla striata has been used as traditional Chinese medicine for several centuries. In recent years, the quality and quantity of wild B. striata plants have declined sharply due to habitat deterioration and human over-exploitation. Therefore, it is of great urgency to evaluate and protect B. striata wild plant resource. In this study, sequence-related amplified polymorphism (SRAP) markers were applied to assess the level and pattern of genetic diversity in twelve populations of B. striata. The results showed a high level of genetic diversity (PPB = 90.48%, H = 0.349 4, I = 0.509 6) and moderate genetic differentiation among populations (G(st) = 0.260 9). Based on the unweighted pair-group method with arithmetic average (UPGMA), twelve populations gathered in three clusters. The cluster 1 included four populations. There are Nanjing, Zhenjiang, Xuancheng and Hangzhou. The seven populations which come from Hubei Province, Hunan Province, Jiangxi Province and Guizhou Province belonged to the cluster 2. The cluster 3 only contained Wenshan population. Moreover, Mantel test revealed significant positive correlation between genetic distances and geographic distances (r = 0.632 9; P < 0.000 1). According to the results, we proposed a series of conservation consideration for B. striata.

OBJECTIVETo establish a culture method for a large amount of highly purified osteoclast-like cells in vitro. To investigate the gene expression of some osteoclast marker enzymes. To lay the foundation for the further study of the signal path on the differentiation and formation of osteoclast-like cells.

METHODSThe bone marrow mononuclear cells of rat were treated with 30 ng/mL macrophagecolony-stimulating factor (M-CSF) and 50 ng/mL receptor activator of NF-kappaB ligand (RANKL) and cultured for 6 days. After culturing, cells were evaluated by morphology observation, tartrate-resistant acid phosphatase (TRAP) staining, Giemsa staining, pit staining, and the gene expression of some osteoclast marker enzymes.

RESULTSThe TRAP-positive mononuclear cells were more frequently observed than the multinucleated cells and pit staining could be seen on the dentine slice. The transcription expression of TRAP, matrix metalloproteinase-9 (MMP-9), membrane-type1-matrix metalloproteinase (MT1-MMP) and cathepsin K were detected by RT-PCR.

CONCLUSIONThe cooperation of M-CSF and RANKL could induce a large amount of highly purified osteoclast-like cells formation in rat bone marrow culture. The typical characteristics of osteoclast-like cells were demonstrated and the enriched osteoclast-like cells expressed TRAP, MMP-9, MT1-MMP and cathepsin K.
