Objective: To compare the eradication rates of H. pylori infection between a new sequential treatment regimen and conventional triple therapy in functional dyspepsia patients, and to assess the symptom improvement of functional dyspepsia. Methods: One hundred and thirty functional dyspeptic patients with H. pylori infection were randomly divided into 2 groups. Patients in sequential treatment group received 10-day sequential therapy: omeprazole (40 mg daily) plus amoxicillin (1 g twice daily) for the first 5 days, followed by omeprazole (20 mg), clarithromycin (500 mg) and tinidazole (500 mg) twice daily for the another 5 days; patients in triple therapy group received standard 7-day treatment: omeprazole (20 mg), clarithromycin (500 mg) and amoxicillin (1 g) twice daily for 7 days. H. pylori statuses were assessed by rapid urease test and 14C-urea breath test at base line level 4 weeks and one year after treatment, and symptom scores in various H. pylori statuses were evaluated. Results: The eradication rates of H. pylori in the sequential treatment group was 83.58% (56/67) by intention-to-treat(TTI) analysis and 91.80% (56/61) by per-protocol (PP) analysis, and the numbers in the triple therapy group were 65.08% (41/63) and 69.49% (41/59), respectively, which were significantly lower than those in the sequential treatment group (P<0.05). The symptom scores of patients with H. pylori eradicated after treatment were 4.88±1.76 before treatment and 2.18±0.83 one year after treatment (P<0.05); the scores of patients whose H. pylori was not eradicated after treatment was 4.99±1.66 before treatment and 3.89±1.56 one year later; there was no significant difference between the 2 numbers. Conclusion: Sequential treatment regimen has a better H. pylori eradication effect for functional dyspepsia patients positive of H. pylori than standard triple therapy; the symptom of dyspepsia can be greatly improved after H. pylori eradication.

OBJECTIVETo study the effects of sacral nerve root electrostimulation (SNS) on the colon function and its mechanisms in rats with spinal cord injury (SCI).

METHODSOne hundred and four Wistar rats were divided into three groups: A, B and C. A group ( n = 24) was divided into three subgroups (n = 8) for studying the bioelectricity: Normal group (NG), SCI group (SCI) and SCI group with SNS(SNS); B group( n = 24) was divided into three subgroups( n = 8) for studying the colon motility: NG, SCI and SNS. C group( n = 56) were divided into three groups for studying the change of morphology and neurotransmitters(SP and VIP): NG (n = 8), SCI (n = 24), and SNS (n = 24) . In SCI and SNS, included of three subgroups: 24, 48, 72 h after spinal cord injury (n = 8).

RESULTSIn SCI group, the activity of bioelectricity in proximal and distal colon was reduced; the colon motility was lessened, and colon mucosa appeared different degree of damage; cell-cell connections between intestinal epithelial cells were destroyed. The expressions of substance P(SP) and vasoactive intestinal peptide (VIP) in colon were decreased obviously. SNS was found to activate the bioelectricity, promote the colon motility, improve the intestinal mucosal, and increase the expressions of SP and VIP. Conclusion: SNS can activate the peristalsis, rehabilitate the motility of denervated colon, protection of the intestinal mechanical barrier between intestinal epithelial cells and tight junction, rebuild the colon function through activating the bioelectricity and increase the expressions of SP and VIP.

OBJECTIVETo observe the ultrastructural change of the route of gut bacterial translocation in a rat with spinal cord injury (SCI).

METHODSForty Wistar rats were divided into the following groups: control group and 3 SCI groups (10 in each group). The rats in the SCI groups were established SCI model at 24 h, 48 h, and 72 h after SCI. Small intestine mucous membrane tissue was identified and assayed by transmission electron microscope, scanning electron microscope and immunofluorescence microscopy.

RESULTSSmall intestine mucous membrane tissue in control group was not damaged significantly, but those in SCI groups were damaged significantly. Proliferation bacteria in gut lumen attached on microvilli. The extracellular bacteria torn the intestinal barrier and perforated into the small intestinal mucosal epithelial cell. The bacteria and a lot of particles of the seriously damaged region penetrated into the lymphatic system and the blood system directly. Some bacteria were internalized into the goblet cell through the apical granule. Some bacteria and particles perforated into the submucosa of the M cell running the long axis of M cells through the tight junctions. In the microcirculation of mucosa, the bacteria that had already broken through the microvilli into blood circulation swim accompanying with erythrocytes.

CONCLUSIONThe routes of bacterial translocation interact and format a vicious circle. At early step, the transcellular pathway of bacterial translocation is major. Following with the destroyed small intestine mucous, the routes of bacterial translocation through the lymphatic system and the blood system become direct pathways. The goblet cell-dendritic cell and M cell pathway also play an important role in the bacterial translocation.

Objective To explore the pattern and quantify the heat shock protein HSP)70 and HSP70 mRNA in Vero-E6 cells after infection with Hantann virus(HTNV).Methods The expres- sion of HSP70 and change of its mRNA level were detected by immunocytochemical staining,nucleic acid hybridization in situ and RT-PCR.Results In situ hybridization and RT-PCR were used to eval- uate the level of HSP70 mRNA during Hantaan 76-118 infection.HSP70 mRNA increased 0.5 h after infection,reached its peak by 12 h and gradually declined to steady state level by 72 h(vs.sham infec- ted group,P＜0.05).The expression of HSP70 protein induced by Hantaan 76-118 infection was e- valuated by quantitative immunocytochemical staining.HSP70 increased 0.5 h after infection,reached its peak by 12 h and decreased at 72 h after infection(vs.sham infected group,P＜0.05).Conclu- sions HSP70 can be induced directly by HTNV infection at both mRNA and protein levels,It pro- vides a basis for the further study of the pathogenesis,prevention and treatment of hemorrhagic fever with renal syndrome(HFRS).

The distribution and morphology of supraependymal cells residing within thethird ventricle of the adult rabbit and adult rat have been investigated by means ofscanning electron microscopy.Supraependymal cells can be classified into twofundamental types,those with neuronal characteristics were designated Type Ⅰ incontrast to those that appear to be macrophagic in character,which were termedType Ⅱ.The neuron-like supraependymal cells have oval cell bodies and long slen-der processes.They occurred not only singly along the ventricular surface,but alsotended to occur in clusters which may be named as neuronal complex.Usually theneuronlike structures possessed varicose fibers of various calibers,runing among thecilia,microvilli,and bulbous protrusions of the ependymal surface.The morphologyof macrophage-like ependymal cells are variable.In general,they had one or severalbroad pseudopodia.According to the number of processes,the macrophage-likesupraependymal cells may be divided into three main types.The morphology of supraependymal cells within the third ventricle of the rabbitand rat is quite similar.The role of supraependymal cells were discussed.

Hypoxia inducible factor (HIF-1α) is a hypoxia response regulator,which is highly expressed in malignant tumors.Researches have shown that HIF-1α plays an important role in epithelial mesenchymal transformation.It can regulate epithelial mesenchymal transition through a series of signal pathways and mechanisms at many levels,to participate in the invasion and metastasis of tumors.To explore the mechanism of HIF-lα controlling epithelial mesenchymal transformation has important significance for the development of new,effective tumor treatment methods.

Objective To evaluate graft isometry after anatomic single bundle reconstruction of anterior cruciate ligament (ACL) using dynamic computed tomography (CT).Methods A retrospective study was conducted of the 14 patients who had undergone single bundle ACL reconstruction from June to August 2015.They were all men,with an average age of 28.6 years (range,from 18 to 39 years).At 6 months after operation,they received dynamic CT scanning during a cycle of knee extension to flexion.3D bone models representing the knee at different flexion positions (0°,30°,60°,90°,and 120°) in each patient were reconstructed from the CT images.The grid method was used to locate the positions of the central footprints of the tibial and femoral tunnels.The lengths between the entries of the femoral and tibial tunnels were measured from each tunnel entry to reflect the graft length change.Furthermore,we measured the isometry at the over-the-top position of the femur and at the anatomic tibial position.Results All the tunnel entries were located at the central area of the ACL anatomic attachment.The reconstructed ACL was the longest when the knee was in full extension.The length was gradually shortened between the femoral and tibial tunnels during flexion of the knee from 0° to 90°.The anatomic position showed an average of 4.82 mm shortening and the over-the-top position an average of 3.28 mm shortening.The length excursion increased in early flexion from 0° to 30° (2.91 ±0.91 mm on average) and reduced in later flexion from 90° to 120° (2.98 ± 1.41 mm on average).Conclusions None of the reconstructed ACL was isometric.A graft length may be the longest when the knee is in full extension and decrease gradually during the flexion from 0° to 90° and increase gradually during the flexion of 90° to 120°.The graft should be fixed when the knee is in the flexion of 30°.

Objective To investigate the clinical characteristics,diagnosis and therapeutic prognosis of Pneumocystis pneumonia(PCP)in patients with acquired immunodeficiency syndrome (AIDS).Methods AIDS patients with PCP were searched through computer medical record information system,clinical data were analyzed retrospectively,patients were divided into respiratory failure group (n= 1 1 )and non-respiratory failure group (n= 1 2 ),partial pressure of oxygen in arterial blood(PaO2 ),degree of blood oxygen saturation(SaO2 ),CD4+T lymphocyte,and lactate dehydrogenase(LDH) between two groups were compared. Results 23 patients generally had the symptoms of weight loss,oral leukoplakia, shortness of breath,dyspnea,fever,cough,and expectoration. PaO2 value in 23 patients was (78.65±30.85)mmHg,partial pressure of carbon dioxide(PaCO2)was (24.42±5.60)mmHg,pH value was(7.43±0.79),SaO2 was (91.16±9.55)% ;SaO2 and PaO2 in respiratory failure group was lower than non-respiratory failure group,the difference was significant (both P<0.05).Lung computed tomography (CT)scans showed bilateral pulmonary ground-glass-like change. 21 patients used compound sulfamethoxazole tablets,1 patient used compound sulfamethoxazole tablets plus clindamycin,1 patient used only clindamycin,17 patients used glucocorticoid in addition to compound sulfamethoxazole;after treatment,20 patients improved,2 died,and 1 gave up treatment.Conclusion Subacute progressive dyspnea,fever,dry cough,and lung ground-glass-like shadow are common symptoms of PCP in AIDS patients,compound sulfamethoxazole or compound sulfamethoxazole with clindamycin can be used for treatment,glucocorticoid can obviously alleviate the symptoms of patients.

OBJECTIVETo observe the effect of Angong Niuhuang Pill (ANP) on Thl/Th2 in cerebral infarction patients and to explore the mechanism of phlegm-heat obstructing orifices.

METHODSRe- cruited were 30 cerebral infarction patients of phlegm-heat obstructing orifices syndrome (PHOOS) both in China and Indonesia. They were assigned to 4 groups according to the use of ANP, the Chinese treatment group, the Indonesia treatment group, the Chinese control group, and the Indonesia control group. Patients in the two control groups received conventional treatment, while those in the two treatment group additionally took ANP for 30 successive days. Their adverse reactions were observe, and levels of INF-γ and IL-4 were detected.

RESULTSThe INF-γ level and the INF-γ/IL-4 ratio significantly decreased, and the IL-4 level increased after treatment in the four groups with statistical difference (P < 0.05). Compared with the control group after treatment in the same country, the INF-γ level and the INF-γ/IL-4 ratio were lower, and the IL-4 level was higher in the two treatment groups (P < 0.05). Compared with the two Chinese groups, the INF-γ level and the INF-γ/IL-4 ratio were higher, and the IL-4 level was lower in the two Indonesian groups (P < 0.05). There was no statistical difference in the post-treatment indices between the two treatment groups.

CONCLUSIONSANP had moderating effect on Th1/Th2 in cerebral infarction pa- tients. Cerebral infarction patients of PHOOS might exist certain relation with Th1/Th2.
