Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.

AlM: To study an approach to visual acuity correction after intracapsular cataract extraction by phase - ll intraocular lens implantation through the individualized arcuate keratotomy.
METHODS: For demonstration, 48 postoperative patients ( 50 eyes ) receiving the intracapsular cataract extraction were gathered up. Each patient received a scleral tunnel major incision along the radial line of the maximum corneal refractive power determined by a cornea curvimeter, and a arcuate keratotomy was made opposite to the major one; through the major incision an iris-claw intraocular lens is implanted. Each patient was measured for their corneal astigmatism and uncorrected visual acuity before and after the surgery.
RESULTS: The results suggested the average corneal astigmatism before the surgery and that 3d, 1, 3, 6 and 12mo after the surgery as+3. 18±0. 68,-1. 56±0. 73,+0. 87± 0. 51, + 1. 21 ± 0. 70, + 1. 33 ± 0. 68 and + 1. 48 ± 0. 48 respectively. The uncorrected visual acuities 3d, 1, 3, 6 and 12mo after the surgery are 0. 5±0. 38, 0. 56±0. 23, 0. 55± 0. 24, 0. 52±0. 28 and 0. 51±0. 25 respectively.

OBJECTIVETo observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.

METHODSWe treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.

RESULTSStapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).

CONCLUSIONCircumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.

OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.

METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.

RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.

CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

To study the metabolite excretion of theophylline, a rapid and specific method by liquid chromatography with heated electrospray ionization tandem mass spectrometry (LC-HESI/MS/MS) method for simultaneous determination of theophylline, 1, 3-dimethyluric acid (1,3-DMU), 3-methylxanthine (3-MX) and 1-methyluric acid (1-MU) in human urine was developed using theophylline-d6 and 5-fluorouracil as internal standards. Selected reaction monitoring (SRM) with heated electrospray ionization (HESI) was used in the negative mode for mass spectrometric detection. After diluted with methanol and centrifuged, the analytes and ISs were separated on a XDB-Phenyl (150 mm x 4.6 mm, 5 microm) column with a mixture of water-methanol-formic acid (30 : 70 : 0.15) as mobile phase at a flow rate of 0.6 mL x min(-1). The linear calibration curves for theophylline, 1, 3-DMU, 3-MX and 1-MU were obtained in the concentration range of 1.0-250 microg x mL(-1), separately. The method herein described is effective and convenient, and can be used for determination of theophylline and its three metabolites. The results showed that urinary excretion ratio of theophylline, 1,3-DMU, 3-MX and 1-MU is approximately 1 : 3 : 1 : 2 in Chinese subjects, which is similar to the reported excretion pattern in Caucasian.

Objective To analyze the clinical characteristics , diagnosis, therapy and prognosis of new diagnosed pri-mary gastric diffuse large B cell lymphoma ( PGDLBCL) and to discuss the efficacy of rituximab .Methods Between Jan 2005 and May 2012 , twenty-six new-diagnosed PGDLBCL patients were reviewed retrospectively .The clinical characteris-tics, diagnosis, therapy, results and prognostic factors were analyzed .Results There were 14 males and 12 females.Their age ranged from 25 to 82 (median, 50.1) years old.The most common symptom was stomachache .Treatment strategies were chemotherapy alone ( n=9) [ scheduled as cyclophosphamide , doxorubicin , vincristine and prednisone ( CHOP) and CHOP-like] and chemotherapy combined with rituximab (n=17), followed by radiotherapy of the stomach with or without regional nodes .All clinical and pathological features were similar between the two groups .The median follow-up time was 40 months.The overall response rate was 100%(9/9)in CHOP group, including 55.56%(5/9) CR, and 93.75%(15/16) in RCHOP group including 50%(8/16) CR (P>0.05).The total PFS and OS of 5 years were 60.3%and 74.4%respectively.The PFS in CHOP group and RCHOP group was 66.7% and 58.9%, respectively,and the OS was 66.7%and 84.6%, respectively.Although the OS of RCHOP group was much better than that of CHOP group , there was no sta-tistically significant difference.Univariate analysis showed that IPI (P<0.05) and Lugano staging (P<0.05) were inde-pendent factors of survival in patients with PGDLBCL .Conclusion Chemotherapy could be the first-line therapy of PGDL-BCL.The overall survival rate might be increased by adding rituximab to chemotherapy .The Lugano stage and IPI are im-portant prognostic factors .

Objective To investigate the therapeutic effect and adverse effects of the teniposide-based regimen in patients with primary central nervous system lymphoma (PCNSL). Methods Between March 2011 and July 2013, 16 patients with PCNSL were diagnosed and treated. The clinical characteristics, diagnosis,therapy, results and adverse effects were analyzed. Results Totally 16 patients were enrolled and diagnosed as primary central nervous system diffuse large B-cell lymphoma. All patients received teniposide-based regimen chemotherapy and 9 patients received teniposide plus rituximab. The overall response rate was 87.5 % (14/16), including 10 cases of CR and 4 cases of PR. With a median follow-up of 13.5 months, the progression-free survival (PFS) and overall survival (OS) rates of 2 years were 29.9 % and 66.7 %, respectively. The mainly hematological adverse events were neutropenia, including grade 3 in 4 cases (25 %) and grade 4 just in one case. There was one case of treatment related death. Conclusions The response rate of teniposide-based regimen for PCNSL is promising. The 2 year PFS and OS rates are even higher than results of traditional high-dose methotrexate regimen. The teniposide-based regimen is well tolerated, and the adverse events are acceptable.
