Objective To discuss the methods and clinical effects of phased treatment of ankylosing spondylitis (AS) combined with severe hip flexion contracture.Methods The study enrolled 8 cases (12 hips) of AS combined with severe hip flexion contracture hospitalized from September 2011 to November 2012.Phased treatments included lateral hip arthrolysis,articular capsulectomy,stripping of the reflected head of rectus femoris,femoral neck osteotomy,traction and stage Ⅱ biotype total hip arthroplasty (THA).Preoperative and postoperative Harris score,hip range of motion,and complication of femoral nerve injury were detected.Results Period of follow-up was 6-12 months (mean 10 months).One case developed heterotopic ossification,which affected postoperative hip activity and received resection one year later.One case sustained fissure fracture of calcar femorale during implantation of the prosthetic femoral stem,but no special handling was provided.Of all cases,active flexion and extension of the hip were both 0° before operation,but increased to (96.25 ± 4.33) ° and (24.17 ± 4.69)° respectively after operation ; mean Harris score was improved from (26.67 ± 2.39) points preoperatively to (90.92 ± 5.66) points postoperatively (P ＜ 0.01).Besides,no femoral nerve injury was observed.Conclusion Phased treatment of AS combined with severe hip flexion contracture restores hip function and minimizes femoral nerve injury following THA.

Objective To investigate the clinical significance of CD14+HLA-G+ monocytes in pe-ripheral blood and the soluble form of HLA-G ( sHLA-G ) in plasma among patients with gastric cancer ( GC) . Methods Blood samples were collected from 135 patients with gastric cancer ( GC group) , 150 pa-tients with chronic gastritis ( CG group) and 80 healthy controls ( HC group) . Flow cytometry analysis and ELISA were used to detect the percentages of CD14+HLA-G+ monocytes in peripheral blood samples, the concentrations of sHLA-G in plasma samples and the levels of alpha fetoprotein (AFP), cacino-embryonic antigen ( CEA) , CA19-9 and CA125 in serum samples. Mann-Whitney U test was performed to analyze the differences between different groups. The feasibility of using CD14+HLA-G+ monocytes, sHLA-G, AFP, CEA, CA19-9 and CA125 as potential biomarkers to differentiate patients with GC from those with CG or healthy subjects was assessed by using receiver operating characteristic ( ROC ) curve analysis. Results The median percentages of CD14+HLA-G+ monocytes in subjects from GC, CG and HC groups were 18. 6% (12. 1%-26. 7%), 7. 3% (4. 2%-11. 0%) and 4. 6% (3. 6%-6. 3%), respectively. The percentages of CD14+HLA-G+monocytes in the peripheral blood of patients with GC were significantly higher than those in patients with CG and healthy subjects (P<0. 001). The concentrations of sHLA-G in plasma samples collected from patients with GC [(100. 6±61. 3) U/ml) were significantly higher than those in pa-tients with CG [(59.5±19. 9) U/ml) and healthy subjects [(45. 8±23. 3) U/ml] (P<0. 001). ROC curve analysis showed that in terms of GC diagnosis, the area under ROC curve ( AUC) , cutoff value, sensi-tivity and specificity for CD14+HLA-G+monocytes and sHLA-G in plasma were 0. 893 and 0. 720, 12% and 85 U/mL, 75. 8% and 50. 5%, 86. 7% and 95. 9% (P<0. 001), respectively, which indicated that CD14+HLA-G+ monocytes and sHLA-G were better than AFP, CEA, CA19-9 and CA125 in differentiating GC from CG and HC. Moreover, the multivariate logistic regression analysis revealed that the CD14+HLA-G+ monocytes, sHLA-G in plasma as well as CA19-9 and CA125 in serum were positively correlated with the risk of GC after excluding the differences caused by age and gender factors. Conclusion The levels of CD14+HLA-G+ monocytes in peripheral blood and sHLA-G in plasma increased dramatically in patients with gastric cancer, which suggested that CD14+HLA-G+monocytes and sHLA-G might be risk factors for GC and could be used as potential biomarkers for the diagnosis of GC.

OBJECTIVETo observe the effect of Panax notoginseng saponins (PNS) on serum content of neuronal specific enolase (NSE) and function recovery in patients with cerebral hemorrhage (CH) for exploring the therapeutic action of PNS in treating CH.

METHODSFifty CH patients with their course of disease not more than 5 days were randomly assigned to two groups, 27 in the PNS group and 23 in the control group, all were treated with conventional treatment, while PNS was given additionally to the PNS group. The serum levels of NSE before and after treatment were determined by electrochemiluminescence, and the recovery of patients, including their neuro-function deficit and daily living activity, was assessed according to scoring by the National Institute of Health Stroke Scale (NIHSS) and Barthel Index (BI) respectively.

RESULTSBefore treatment, the difference between the two groups in serum NSE content and scores of NIHSS and BI was insignificant (P > 0.05). However, after 3 weeks of treatment, the level of NSE and score of NIHSS were significantly lower, while score of BI was significantly higher in the PNS group than those in the control group respectively (all P < 0.01). In the PNS group, the level of NSE showed a positive correlation with the score of NIHSS (r = 0.757, P < 0.05), and a negative correlation with the score of BI (r = - 0.803, P < 0.05).

CONCLUSIONPNS can effectively protect the neuron and promote functional rehabilitation in patients after CH.

OBJECTIVETo investigate the status of genital infection as well as distribution of types of human papillomavirus (HPV) in women in Shenzhen and provide population data for the future vaccine intervention on cervical cancer.

METHODSWomen with age between 15 and 59 years were selected in cluster stratified sampling from Huaqiaocheng community, Nanshan district, Shenzhen and received a population-based cervical cancer screening. After consent, every woman was interviewed by using questionnaire and tested by liquid-based cytology and HPV DNA (hybrid capture 2 and gene chips typing) separately.

RESULTSTotally 1 137 women were screened. The rate of high risk HPV of hybrid capture 2 test (14. 0% ) was higher than gene chips typing test (9. 8%) (chi(2) = 27. 198, P < 0. 001) ; the consistency of the two tests was acceptable ( kappa = 0. 498, P < 0. 001). The rates of low risk HPV types and other types of gene chips typing test in this population were 1. 9% and 0. 2% respectively. The percentages of HPV 16, 18 and 58 in HPV positive women were 29. 7% , 18. 9% and 18. 9%. The rates of different age group of low risk HPV were 1. 4% (17-34), 1. 7% (35-44) and 3. 2% (45-59) , respectively.

CONCLUSIONSHPV 16, 18, and 58 are the most popular types in the study population. The differences of infection rates of high risk HPV are due primarily to the variation of HPV16 distribution among age-specific population. The chances of being affected by low risk HPV will increase with age.
