Objective To investigate the change of homocysteine (Hcy),high sensitive C-reactive protein (hs-CRP)and Inter-leukin 6 (IL-6)in patients with Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS)complicated by Cerebral Infarction (CI).Methods Chose 55 patients with OSAHS and 56 patients with CI.All patients with OSAHS were divided into mild group,moderate group and severe group by polysomnography,and all patients were divided into simple OSAHS group,sim-ple CI group and OSAHS complicated by CI group.All the patients’sleep apnea hypoventilation index (AHI),the lowest oxygen saturation (LSpO2 ),average blood oxygen saturation (MSpO2 ),sleep apnea the longest (LAT)and the level of Hcy,hs-CRP,IL-6 were determined,and compared with 30 cases of control group.Results The AHI,LAT,Hcy,hs-CRP and IL-6 of simple OSAHS group and simple CI group were obviously higher than that in control group,LSpO2 ,MSpO2 were obviously lower,the differences were statistical significant (P<0.05).The AHI,LAT,Hcy,hs-CRP and IL-6 of OS-AHS complicated by CI group were obviously higher than that in simple groups,but LSpO2 and MSpO2 were obviously low-er,and the differences were statistical significant (P<0.05).With the aggravation of OSAHS,Hcy,hs-CRP and IL-6 were gradually increased.Hcy,hs-CRP and IL-6 were positively correlated with AHI in patients with OSAHS,correlation coeffi-cient were 0.751,0.678 and 0.635,respectively (P<0.001).Conclusion OSAHS was closely related to the occurrence and development of CI,the dynamic monitoring of Hcy,hs-CRP and IL-6 levels has a certain reference value for evaluation of therapeutic effect.

Peliosis hepatis is a rare benign hepatic vascular disease.There is the lack of specific clinical features and preoperative diagnosis.A patient with intermittent liver area pain was admitted to the Third Central Hospital of Tianjin in April 2014.The patient with space-occupying lessions of the right lobe of liver was preliminarily diagnosed as with hepatocellular tumor or vasogenic tumor by computed tomography and B ultrasound examinations and then received liver resection combined with cholecystectomy.The result of postoperative pathological examination confirmed peliosis hepatis with adenomatous hyperplasia of liver cells.The patient was followed up till October 20,2014 without recurrence.

Objective To develop a digital polymerase chain reaction (PCR) ribotyping method and database for Clostridium difficile genotyping.Methods Sequencer based fluorescence capillary gel electrophoresis was used,instead of agarose gel electrophoresis,to establish the digital PCR-ribotyping of Clostridium difficile.Forty Clostridium difficile reference strains,consisting of 10 PCR-ribotypes (RT),were genotyped by the new digital PCR-ribotyping method to set-up the database.Results The sequencer based fluorescence capillary gel electrophoresis correctly detected PCR-ribotyping products of the 40 reference strains,and showed as digital figure;significant differences of these digital figures were found between the 10 RT.High similar digital figures were shown in twenty-one RT027 strains,three RT002 strains and two RT014 strains.However,seven RT001 strains were typed as four subtypes,and two RT014 strains as two subtypes,respectively.Conclusion A digital PCR-ribotyping,and a reference database consisting of 10 RT are successfully established.

Objective To investigate 13 high-risk types of HPV (HR HPV) infection rates in women with different grades of cervical lesions.Methods A total of 350 women, who were hospitalized in the department of gynecology in Bao′an Maternity & Child health hospital, were enrolled for the study.TCT technology was used to evaluate the cervical epithelium.The group were divided according to the cytology results.Multiplex real time PCR (mRT PCR) was used to detect the viral loads.HR HPV infection rate of different groups were analyzed using χ2 test or Fisher exact test.HR HPV viral loads of patients in different grades of cervical lesion groups were compared using Kruskal-Wallis or Wilcoxon test, and the age distribution of HR HPV positive group and negative group was analyzed by using Wilcoxon test.Results The HR HPV infection rates of NILM, ASCUS, LSIL, HSIL were 3.4% (10/295), 20.0% (7/35), 78.6% (11/14) and 100.0% (6/6), respectively.HR HPV positivity in NILM was lower than ASCUS (χ2=14.43,P<0.01) and LSIL (χ2=107.69,P<0.01), HR HPV positivity in ASCUS was lower than LSIL (χ2=14.76,P<0.01). The median of HR HPV viral loads in NILM, ASCUS, LSIL and HSIL were 4.10 (3.38-6.27), 5.33 (3.63-6.66), 5.77 (4.01-7.01) and 5.58 (4.19-5.85) respectively (copies/ml,lg).Combined ASCUS, LSIL and HSIL groups into cervical lesion group, HR HPV viral load of which was higher than that of NILM (U=43.0, P<0.05).The median Ages of HR HPV positive group and negative group were 36 and 33, respectively.No statistical significance was found between them (U=4 544, P>0.05).Conclusions The present study revealed that HR HPV infection was related to cervical lesion, but there was no correlation between viral load and cervical lesion grade. In additional, no difference in age distribution was found between HR HPV positive group and negative group.

BACKGROUND: Researches on the pathogenesis and pathological changes of rheumatoid arthritis(RA) have achieved significant progress in recent years. But traditional Chinese medicine(TCM) has unique advantage in RA therapy.OBJECTIVE: To study effects of overall alkali in tongbiling(TBL) on the proliferation of lymphocytes and the transferrin receptor of T lymphocytes (CD71) to explore the mechanism of TBL on the modulation of cell immunity.DESIGN: A completely randomized grouping design and an explorative study by employing cells as subjects.SETTING: Sixth internal medicine department of a TCM university,center of tissue transplantation and immunology college of life science of a university PARTICIPANTS: The study was conducted in the central laboratory (tertiary laboratory of National TCM Administrator) of the first affiliated hospital of Guangzhou TCM medical university between July 2002 and August 2003. Ten clean male SD rats were selected.METHODS: Lymphocyte was separated from rat inguinal lymph node for culture. Concanavalin(ConA) was used for 72-hour stimulation. The impacts of overall alkali TBL on lymphocyte proliferation were tested by MTT.The expression of T lymphocyte CD71 was tested by flow cytometer after 48-hour stimulation of phorbol 12,13 -dibutyrate(PDB) or ConA.MAIN OUTCOME MEASURES: The impacts of overall alkali TBL on lymphocyte proliferation and T cell activation.RESULTS: Different concentration of overall alkali TBL could significantly inhibit the proliferation of lymphocytes under ConA stimulation. PDB and ConA-activated T lymphocyte CD71 + expressions were significantly higher than that of blank control group(P<0.01) . CD3+ CD71 + expressions [(62.03±1.51) %,(25.28±1.57) %,(20. 29±1.72)%] activated by ConA under different concentration of overall alkali TBL(50,100,200 mg/L)were significantly lower than(72.03±1.28)% of BPS-positive control group (P<0. 05). CD3 + CD71 + expressions activated by PDB under 100 mg/Land 200 mg/L of overall alkali TBL were significantly lower than that of phosphate buffer solution (PBS-)positive control group(P<0.05). Different concentration of overall alkali TBL had significant down-regulated effects on CD71 expression in T lymphocyte activated by PDB or ConA and there was also a significant dose-effect relationship(P<0. 05). The inhibition on ConA-activated CD71 expression was stronger than that of PDB.CONCLUSION: Overall alkali TBL can inhibit the abnormal proliferation of T lymphocyte and its mechanism might be realized through its inhibition on transferrin receptor.

Objective To introduce the experience of improved posterolateral mini-incision total hip urthroplasty(THA)in treatment of femoral neck fractures.Methods Of 199 patients(207 hips)treated with preliminary THA from October2002 to January 2005,them were46 patients(46 hips)with femoral neck fractures including31 fresh fractures and 15 old ones,which were then treated with posterolateral mini-incision THA.An observation was done on length of incision,operation time,volume of blood loss,drainage volume,hospital stays,postoperative complications,functional recovery and Harris score.Results All patients were followed up for 14-26 months(mean 17.2 months).The final Harris score during follow-up was(84.1±8.6)points in the fresh fracture group and(85.8±7.6)points in the old fracture group.Pestoperative X-ray showed sound position of the prosthesis.There was no statistical difference upon length of incision,operation time,blood loss,drainage volume and hospital stays between fresh fracture group and old fracture group(P＞0.05).Dislocation occurred in one patient in each group.Conclusion Posterolateral mini-incision THA is proved to be successful in reducing surgical trauma,accelerating rehabilitation and decreasing blood loss and complications for patients with femoral neck fractures.

Objective To study the relationship between homocysteine (Hcy)and carotid atherosclerosis in patients with cer-ebral infarction.Methods During January and November 2013,281 patients with cerebral infarction from Affiliated Hospital of Yan’an University were provided the blood samples as cerebral infarction group,140 healthy volunteers served as control group.Serum Hcy was detected by enzymatic cycle assay.According to the results of carotid artery ultrasonography,cerebral infarction group was divided into five groups:artery normal group,intimal thickening group,soft plaque group,mixed plaque group and hard plaque group.The statistically significance was analyzed by SPSS 19.0.Results The serum Hcy level of cer-ebral infarction group was 19.78 ± 5.21 μmol/L,significantly higher than the control group 10.24 ± 3.33 μmol/L (P <0.001).The serum Hcy levels of control group,artery normal group,intimal thickening group,soft plaque group,mixed plaque group and hard plaque group were 10.24±3.33,15.20±2.99,17.03±1.85,25.44±4.24,19.65±4.74 and 18.31 ±3.67 μmol/L respectively.The differences between groups were statistically significant in addition to intimal thickening group and hard plaque group (P =1.106).The positive rates were 16.4%,53.7%,87.1%,95.7%,83.1% and 77.3% re-spectively,the groups which in cerebral infarction group compared with control group,the differences were statistically sig-nificant (P <0.001).Conclusion Hcy played an important role in the occurrence and development of cerebral infarction. Lower serum Hcy concentration,may be an effective way to prevent carotid atherosclerosis and cerebral infarction.

[Objective]To observe the effects of total alkaloids (TA) of Tongbiling (TBL) prescription on proliferation of T lymphocytes and transferring receptor of T lymphocytes (CD71) in rats and to explore the mechanism of TBL in regulating cellular immunity. [Methods]Isolated lymphocytes from mesenteric lymph node were cultured with various concentrations of TBL TA and canavaline A (ConA) for 72 hours; the proliferation of T lymphocytes was observed by MTT method and CD71 expression rate of T lymphocyte activated by phorbol 12,13-dibutyrate (PDB) or ConA for 48 hours was detected by flow cytometry.[Results]Various concentrations of TBL TA inhibited the proliferation of T lymphocytes activated by ConA and decreased CD71 expression rate of T lymphocyte activated by ConA or PDB in a dose-effect manner. Inhibitory effect of TBL TA on CD71 expression rate of T lymphocyte activated by ConA was superior to that activated by PDB. [Conclusion]TBL TA can inhibit the abnormal proliferation of T lymphocytes and its mechanism may be related to the expression of CD71.

Objective:To study deeply on the effects of sinomenine on Th1 type cytokines expression of T lymphocytes.Methods:The authors isolated and cultured the mesenteric lymph nodes of mice in vitro.The lymphocytes were stimulated with PDB and inomycin after added sinomenine in different concentrations for 1 hour.After 4 hours stimulation,cells were collected and stained intracellular cytokines with the dying regents,then the expression of Th1 type cytokine IFN-?,pro-inflammatory cytokine TNF-? of T lymphocytes were analyzed by flow cytometry.And also observed the effects of drugs on the expression of CD69,an early marker of T cell activation.Results:1 000 ?mol/L(329.4 ?g/ml)sinomenine can downregulate CD69 expression of T lymphocytes while 200 ?mol/L sinomenie show no effect on it.200,1 000,2 000 ?mol/L sinomenine can obviously reduce the expression of intracellular cytokines such as IFN-?,TNF-? in dose-dependent manner.Conclusion:One of the immunological mechanisms of sinomenine to treat rheumatoid arthritis may due to the inhibitory effects on abnormal T lymphoctytes activation.The inhibitory effects of sinomenine may mainly be relative to the inhibitory effects on Ca 2+ -dependant signal pathway of T lymphocytes activation but not PKC pathway.

OBJECTIVE: To evaluate the immediate effect of moxibustion at Shenshu (BL 23) on renal hemodynamics in patients with chronic kidney disease(CKD)．. METHODS: Thirty-two non-dialysis patients with CKD were recruited in this study. Moxibustion was applied at bilateral BL 23 for 30 min. The peak systolic velocity (PSV), end diastolic velocity (EDV) of the interlobar renal artery were measured by Doppler ultrasonography (US) before, and 0 and 15 min after moxibustion. The renal resistance index (RI) was equal to (PSV－EDV)/PSV. The body temperature (T), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) were also monitored at the same time points. RESULTS: After moxibustion, the EVD level at 15 min after moxibustion was significantly increased (P<0.05), and the renal RI levels at 0 and 15 min after moxibustion were significantly down-regulated in comparison with their own pre-treatment (P<0.01). No significant changes were found in the levels of PSV, T, SBP, DBP and HR after moxibustion (P>0.05). CONCLUSION: Moxibustion at BL 23 can increase EDV and reduce renal RI of the interlobar renal artery in patients with CKD, which may be useful in relieving kidney disorders by improving renal blood flow.
