Xiatianwu tablet is based on the theory of traditional Chinese medicine (TCM), combined with modern TCM pharmacology and selected 33 famous traditional Chinese crude drugs to compose. Its recipe helps cure rheumatism, relax tendons, promote blood circulation to relieve pain, et al. Although Xiatianwu tablets are widely applied to clinical remedy such as rheumatic arthritis, lumbar disc hernia, osteoarthritis and so on, there is no report about its application in fracture. This article is to observe the efficacy of compound Xiatianwu tablets in elderly patients with osteoporotic distal radius fractures and its impact on the wrist function and complications. 180 elderly patients with osteoporotic distal radius fractures, from January 2011 to June 2014, were divided into observation group and control group by the method of random number table, each group had 90 cases. The control group were gave Caltrate D after manipulative reduction and plaster immobilization, observation group were treated with compound Xiatianwu tablets in the basis of the control group. Efficacy, wrist function and complication rates were observed in two groups after treatment. The excellent and good rate was 95.56% in observation group better than 77.78% in control group, the difference was statistically significant (χ2 = 4.712, P < 0.05). The complication rate in observation group was significantly lower compared with the control group (P < 0.05). This study shows that compound Xiatianwu tablets can improve the efficacy in elderly patients with osteoporotic distal radius fractures, reduce the incidence of complications and relieve the pain of patients which plays a significant role in improving the quality of life.

OBJECTIVETo investigate the expression of cyclooxygenase-2 (COX-2) in bladder transitional cell carcinoma tissues, and understand its clinical significance.

METHODSReversal transcription polymerase chain reaction (RT-PCR) was used to assess the expression of COX-2 mRNA in 52 cases of bladder transitional cell carcinoma tissues and 17 cases of normal bladder tissues far from neoplasm; Western blot was used to assess the expression of COX-2 protein in 49 cases of bladder cancerous tissues and 17 cases of normal tissues.

RESULTSPositive expression of COX-2 mRNA was detected in 83% (43/52) of bladder cancer tissues and in 29% (5/17) of normal tissues by RT-PCR and there was significant difference in expression of COX-2 mRNA between cancer tissues and normal tissues. Western blot analysis showed that expression of COX-2 protein was correlation with the stage and grade of cancer.

CONCLUSIONCOX-2 is overexpressed in bladder transitional cell carcinoma. COX-2 maybe play a certain role in carcinogenesis and progression of bladder cancer and turn into a useful target of chemoprevention of bladder cancer.

BACKGROUNDLiver transplantation is the most effective treatment for patients with end-stage liver failure, however infection after transplantation is a serious clinical complication. The purpose of this research was to investigate the molecular epidemiology and the influence of multidrug-resistant Gram-positive infection in patients, following liver transplantation, to provide reference for clinical treatment and prevention of Gram-positive bacterial infection.

METHODSWe isolated and detected bacteria from phlegm, throat swabs, urine, wound or wound secretions, blood, and fecal samples from 221 liver transplant patients in our hospital from January 2007 to April 2010. All isolated bacterial strains were identified and tested by minimal inhibitory concentration (MIC) drug-sensitive detection using the BioMerieux ATB bacterial identification instrument and repetitive extragenic palindromic-polymerase chain reaction (REP-PCR) detection of bacterial homology. Risk factors were calculated by multivariate Logistic regression analysis.

RESULTSWe collected 250 specimens from 221 patients hospitalized following liver transplantation surgery, of which 29 patients developed multiple infections. Sixty-five Gram-positive bacterial strains were isolated from different specimens from 53 infectious patients. We detected 29 multidrug-resistant Gram-positive strains from 29 patients (44.62%), including 20 Staphylococcus aureus (S. aureus) strains (68.97%) and nine Enterococcus strains (31.03%). All 20 S. aureus strains were highly resistant to aminoglycosides (gentamicin), cephalosporins (cefoxitin), quinolones (ciprofloxacin and levofloxacin), lincomycins (clindamycin), penicillin, and erythromycin. The resistance rate reached 100% in some cases. The S. aureus strains were highly sensitive to vancomycin and oxazolidinone (linezolid), with MIC50 < 2 µg/ml for both. The nine Enterococci strains were also highly resistant to aminoglycosides, quinolones, and penicillins, and highly sensitive to vancomycin (MIC50 < 2 µg/ml) and oxazolidinone (MIC50 < 1 µg/ml). Using REP-PCR detection, S. aureus was divided into five genotypes with 14 B-type strains. Enterococcus was divided into 11 genotypes, with two D-type strains, two G-type strains, and two K-type strains. The risk factors for Gram-positive bacterial infection in patients following liver transplantation were preoperative use of antibiotics (OR = 3.949, P = 0.004), high intra-operative blood input (OR = 1.071, P = 0.005), and postoperative renal failure (OR = 5.427, P = 0.043).

CONCLUSIONSS. aureus and Enterococcus were the main pathogens causing infection following liver transplantation in patients with drug-resistant Gram-positive bacterial infection. The isolated strains were resistant to multiple antibiotics. B-type S. aureus strains were predominant. Reasonable use of antibiotics, decreasing intra-operative blood input, and preventing post-operative renal failure may reduce Gram-positive bacterial infections and the appearance of drug-resistant strains following liver transplantation.

To improve the targeting of adenovirus vector for gene therapy, a fusion gene sCAR-EGF, in which epidermal growth factor gene was fused to the 3' end of extracellular Coxsackie virus-adenovirus receptor gene, was constructed and cloned into shuttle plasmid pDC315 to obtain a recombinant plasmid pDC315-sCAR-EGF. With the AdMax system, AD-293 cells were co-transfected with pDC315-sCAR-EGF and adenovirus genomic plasmid pBHGloxdeltaE13cre. Through high efficiency site specific recombination, a replication-defective adenovirus Ad5-CMV-sCAR-EGF was constructed. The recombinant adenovirus was analyzed by PCR and Western blotting, the results indicated that Ad5-CMV-sCAR-EGF contained the fusion gene sCAR-EGF, and the adenovirus infected cells was induced to produce and secrete the fusion protein into the supernatant. We have demonstrated that the fusion protein sCAR-EGF is helpful for elevating the infection efficiency of Ad5-CMV-luc with the reporter gene in vitro, which providing a new approach to the gene therapy for tumors overexpressing EGFR.

Objective To investigate the magnetic resonance multimodal function imaging characteristics of small hepa-tocellular carcinoma and evaluate its diagnostic value in small liver cancer. Methods Thirty-nine patients with small hepato-cellular carcinoma were selected in the First Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2018. The magnetic resonance plain scan data,dynamic enhance data and diffusion imaging data of all patients were analyzed. Results Forty-five lesions were found by plain scan,and 48 lesions(37 lesions were rapid rise and rapid descent type,6 le-sions were flatbed type,3 lesions were slow ascent and rapid descent type,2 lesions were not obvious strengthening type)were found by dynamic enhancement. The lesions were hyperintense or slightly hyperintense on the diffusion weighted imaging (DWI)image. The lesions were hyperintense or slightly hyperintense on the DWI. The main shape of lesions was round,irregu-lar ring and nodositas. The apparent diffusion coefficient(ADC)value of cancer tissue and normal liver tissue gradually de-creased with the increase of b value. Under the same b value,the ADC values of small hepatocellular carcinoma was significant-ly lower than that in the normal liver tissue(P < 0. 05). Conclusion Magnetic resonance multimodality functional imaging (magnetic resonance imaging dynamic enhanced combine with multi-b value DWI)can effectively improve the diagnostic effi-cacy of small hepatocellular carcinoma.

BACKGROUNDAutoimmune encephalitis associated with antibodies against γ-aminobutyric acid B receptor (GABA B R) in patients with limbic encephalitis (LE) was first described in 2010. We present a series of Han Chinese patients for further clinical refinement.

METHODSSerum and cerebrospinal fluid (CSF) samples from patients referred to the program of encephalitis and paraneoplastic syndrome of Peking Union Medical College Hospital were tested with indirect immunofluorescence. Clinical information of patients with anti-GABA B R antibody positivity was retrospectively reviewed, and descriptive statistical analysis was performed.

RESULTSAll eighteen anti-GABA B R antibody-positive cases had limbic syndromes, and electroencephalogram (EEG) or neuroimaging evidence fulfilled the diagnostic criteria of LE. Four patients had additional antibodies against Hu in serum and one had anti-N-methyl-d-aspartate receptor antibody in both sera and CSF. Seventeen (17/18) patients presented with new-onset refractory seizure or status epileptics. Twelve (12/18) patients had memory deficits, 11 (11/18) patients had personality change, 7 (7/18) patients had disturbance of consciousness, and 3 (3/18) patients showed cerebellar dysfunction. One patient with LE had progressive motor and sensory polyneuropathy. Lung cancer was detected in 6 (6/18) patients. Ten (10/18) patients showed abnormality in bilateral or unilateral mediotemporal region on magnetic resonance imaging. Ten (10/18) patients had temporal lobe epileptic activity with or without general slowing on EEG. Seventeen patients received immunotherapy and 15 of them showed neurological improvement. Four patients with lung cancer died within 1-12 months due to neoplastic complications.

CONCLUSIONSOur study demonstrates that most Han Chinese patients with anti-GABA B R antibody-associated LE have prominent refractory epilepsy and show neurological improvement on immunotherapy. Patients with underlying lung tumor have a relatively poor prognosis. Testing for anti-GABA B R antibodies is necessary for patients with possible LE or new-onset epilepsy with unknown etiology.

BACKGROUNDLong-term use of steroid with large dosage might cause many adverse effects in kidney transplant patients; reducing steroid dosage to a low level for maintenance is helpful in avoiding the side-effects, but meanwhile, acute rejection may rise to be a main concern. The present research monitored the immune function changes and the incidence of acute rejection and infection after rapid steroid reduction to investigate the safety of this strategy.

METHODSA prospective trial was conducted, using tacrolimus and mycophenolate mofetil as the basic immunosuppressive regimen, in addition to antibody induction with basiliximab. Corticosteroid dosage was rapidly reduced to 10 mg/d seven days post-transplantation in the experimental group, and the standard corticosteroid therapy was employed in the control group. Patient immunity was monitored by the Immune Cell Function Assay pre- and two weeks post-transplantation. The incidence of acute rejection and infection were compared between the experimental and control group.

RESULTSComparison of intracellular adenosine triphosphate (iATP) values detected two weeks post-transplantation for the control group ((324 ± 45) ng/ml) and the experimental group ((345 ± 91) ng/ml) did not reveal a significant difference (P > 0.05). The incidence of acute rejection was analogous between groups (P > 0.05), while an increased incidence of infection was observed in the control group (53% (n = 16)) versus the experimental group (22% (n = 6), P < 0.05). Overall, recipients in the control group had longer and more recurrent infections than those in the experimental group (P < 0.05). Patients in the control group had a lower immune response ((235 ± 35) ng/ml) than those in the experimental group ((286 ± 16) ng/ml) when infection occurred (P < 0.05).

CONCLUSIONRapid reduction of steroid early after kidney transplantation does not lead to a significant rise in patient immunity. It is a safe and effective therapy for kidney transplant patients.

OBJECTIVETo investigate the incidence and prognosis of 1q21 amplification, 13q14 deletion, TP53 gene deletion and IgH translocation in patients with multiple myeloma (MM).

METHODSInterphase fluorescence in situ hybridization (I-FISH) with four different specific probes for the regions containing 1q21, 13q14.3 (D13S319), 14q32 and TP53 gene were performed in 43 MM patients.

RESULTSAmong the 43 MM patients, 1q21 amplification was observed in 28 (65.1%) cases, 13q14 deletion in 30 (69.7%) cases, TP53 gene deletion in 8 (18.6%) cases, and IgH translocation in 29 (67.4%) cases. The mortality of MM patients with 1q21 amplification, 13q14 deletion or TP53 gene deletion was higher than those without them.

CONCLUSIONThere is high frequency of 1q21 amplification, 13q14 deletion, TP53 gene deletion and IgH translocation in multiple myeloma, and 1q21 amplification, 13q14 deletion and TP53 gene deletion are poor prognosis factors for MM patients.

OBJECTIVETo study the effect of cigarette smoke on the sexual function of male rats.

METHODSBased on Ozyurt's smoking model, we equally divided 30 male adult Sprague-Dawley rats into a control and a smoking group, and exposed the latter to cigarette smoke for 60 days. A week before the end of the experiment, we added 5 female rats to each group and observed their mating through 24-hour video surveillance. Sixty days later, all the rats were killed for the determination of the level of testosterone (T) in the plasma and the activity of nitric oxide synthase (NOS) in the corpus cavernosum, and Masson-dyeing image analysis of the penile tissue.

RESULTSCompared with the controls, the rats in the smoking group showed a significant reduction in the times of mating, the level of plasma T (P < 0.05) and the activity of NOS in the penile cavernous tissue (P < 0.05), but a slight increase in the collagen fibers and obvious changes in the blood sinuses.

CONCLUSIONCigarette smoke seriously affected penile erection in the experimental rats. The decrease in plasma T, NOS activity and the area of smooth muscle may be an important mechanism underlying their erectile dysfunction.
