Objective To investigate the treatment of Navicular bone fracture with Herbert screw.Methods Twenty-three patients with Navicular bone fracture were collected.They were all conducted with CT scan diagnosis and type,the small incision and targeting wire was used in operation.The Herbert screw was used to fix with pressure,plaster was also used to fix.After operation,the activity training was executed gradually.Results We conducted follow-up of 6-18 months in 23 patients,with an average of 12 months.All patients got bone-healing,the healing time ranges from 7 to 10 weeks,with an average of 9 weeks.There was one case of screw penetrating cortical bone,and one case of mild deformity healing,among the other 23 cases there were no complications including infection,nonunion,necrosis,osteoarthritis'etc.Conclusion The treatment of Navicular bone fracture with Herbert screw fixation can get firm fixation,function training and healing early,and it's worth of clinical promotion.

OBJECTIVETo study the clinical effect of combination of kurarinone (KR) and interferon a-lb (IFNalpha-1b) in treating chronic hepatitis B.

METHODSOne hundred and forty-six patients with chronic hepatitis B were randomized into four groups. Under the basic conventional treatment, additional KR combined IFNa-lb was given to Group A, IFNa-lb to Group B and KR to Group C while none was given to Group D. The therapeutic course for them was 6 months and succeeded with 6 months of follow-up. Changes in liver histology, expression of transforming growth factor beta (TGF-beta) in liver tissue, and serum levels of TGF-beta, hyaluronic acid (HA), laminin (LN), collagen type IV (IVC), precollagen III (PCIII), as well as the negative conversion rate of HBeAg and HBV DNA, and normalization rate of alanine transaminase (ALT) before and after treatment were observed by immuno chemical method, RIA and ELISA.

RESULTSAfter treatment, in Group A, the scores of liver fibrosis and all the above-mentioned indexes significantly lowered, as compared with those in Group B and C, the difference was significant (P<0.05 or P<0.01). The negative conversion rate of TGF-beta in liver tissue was in accordance with the dynamic change of liver fibrosis. Comparison between Group B and C in those aspects showed insignificant difference (P >0.05).

CONCLUSIONKR combined with IFNalpha-1b shows better effect in treating chronic hepatitis B than that of using either of the two alone.

Objective: To explore the short and mid-term efficacy of device closure of patent foramen ovale (PFO) for treating the patients with PFO combining cryptogenic stroke (CS) and transient ischemic attack (TIA). Methods: A total of 56 PFO patients with CS and TIA receiving device closure in our hospital from 2009-05 to 2015-12 were retrospectively studied. Transthoracic echocardiography (TTE), electrocardiogram (ECG), chest X-ray were examined at 24h, 1 month, 3 and 6 months after theoperation; telephone visit was conducted every 6 months thereafter. Results: There were 54/56 PFO patients combining CS and 2 combining TIA; 53 (94.6%)patients received PFO occluder from Starway medical technology. Aspirin was used for 6 months after the operation. The patients were followed-up for the average of (34.67±23.24) months. No body suffered from post-operative stroke and TIA; no residual shunt was observed. Conclusion: The short and mid-term efficacy of device closure has been satisfactory for treating the patients with PFO combining CS and TIA; its overall clinical value should be further investigated in large population and long-term study.

The present study aimed to clarify the smoking cessation motivations,challenges and coping strategies among pregnant couples.A qualitative design using a grounded theory approach was applied.Data were collected by individual semi-structured interviews with 39 married individuals (21 non-smoking pregnant women and 18 smoking or ever-smoking men with a pregnant wife) and 3 imams in an ethnically diverse region of far westem China.The most common theme for smoking cessation motivation was "embryo quality" (i.e.,a healthier baby),followed by family's health.Most interviewees reported that husband's withdrawal symptoms were the greatest challenge to smoking cessation,followed by the Chinese tobacco culture.Coping strategies given by the pregnant women typically involved combining emotional,behavioral and social interventions.Social interventions showed advantages in helping to quit smoking.Pregnancy appears to be a positive stimulus for pregnant couples' smoking cessation.Our results suggest that pregnancy,a highly important life event,may help to reduce barriers to smoking cessation at the social level (e.g.,limiting access to cigarettes,avoiding temptation to smoke),but does little to help with the withdrawal symptoms.Professional guidance for smoking cessation is still necessary.

OBJECTIVETo investigate the involvement of E-cadherin-catenin adhesion system in Bowen's disease (BD) and cutaneous squamous cell carcinoma (SCC).

METHODSFifteen normal skin, 28 BD and 18 SCC specimens were stained with monoclonal antibodies against E-cadherin and beta-catenin. Evaluation of the staining results was performed with semi-quantification of the pattern and intensity of staining, percentage of positive cells, and cytoplasmic staining.

RESULTNormal skins strongly expressed membranous E-cadherin and beta-catenin, but their expression was remarkably reduced in BD and SCC. Abnormal staining of beta-catenin was observed in the cytoplasm or cell nuclei of BD and SCC.

CONCLUSIONAbnormal expression of the E-cadherin/catenin complex is common in SCC and BD.

In this paper, the MRI manifestations of 15 patients with benzene toxic encephalopathy were analyzed, and the lesion location, shape, scope and signal were observed. The clinical manifestations of 15 patients were mainly central nervous system damage, and the MRI manifestations were characteristic, with a wide range of lesions, and the shapes were "sunflower-like", "flame-like", "bracket-like" and "butterfly-like", and the MRI signal was sheet-like long T(1), long T(2), fluid attenuated inversion recovery (FLAIR) sequence and diffusion weighted imaging (DWI) high signal, apparent diffusion coeffecient (ADC) map low, equal or high signals. When the patient's diagnosis is unclear, MRI examination may provide clinical basis for diagnosis.

Oridonin, which is an ent-kaurene diterpenoid isolated from traditional Chinese medicine Rabdosia rubescens, displays various bioactivities, including anti-inflammation, anti-bacteria and anti-tumor. This study aimed to investigate the effect of oridonin on apoptosis of triple-negative breast cancer MDA-MB-231 cells and its underlying mechanisms. The inhibitory effect of oridonin on proliferation of MDA-MB-231 cells was measured by MTT assay; Apoptosis was analyzed by flow cytometry with PI staining and Annexin V-FITC/PI staining; Intracellular reactive oxygen species (ROS) level was determined by ROS detection kit, and expressions of PARP, Bcl-2, caspase-3 were analyzed by Western blot. The results showed that oridonin exhibited a significant effect in inducing apoptosis of MDA-MB-231 cells, enhancing intracellular ROS level, down-regulating expression of Bcl-2 protein, and promoting cleavage of caspase-3 and its substrate PARP. These results indicated that the apoptosis-inducing effect of oridonin on MDA-MB-231 cells might be correlated with increase of intracellular ROS level, down-regulation of Bcl-2 protein and activation of caspase-3.
