Objective To assess the status and severity of bone disease in patients with multiple myeloma (MM) by using chest computerized tomography (CT) and the relationship between clinical prognostic parameters and bone disease.Methods All 46 newly diagnosed MM in-patients received both imaging tests of chest CT and plain X ray.An experienced radiologist reviewed all the imaging data.Clinical laboratory parameters,stages of Durie-Salmon (DS) and International Staging System (ISS) were evaluated.Five cytogenetic abnormalities of bone marrow myeloma cells were tested by fluorescence in situ hybridization (FISH).Results The sensitivity of CT and X ray to determine pathological fractures was comparable,the positive rates of which were 41.3％ (19/46) and 30.4％ (14/46) respectively (P =0.29).Nevertheless,the positive rate of osteolytic lesions ascertained by CT was significantly higher than that by X ray (P ＜ 0.001),60.9％ (28/46) vs 13.0％ (6/46) with diameter 5-10 mm and 50.0％ (23/46) vs 10.9％ (5/ 46) with diameter more than 10 mm.Osteolytic lesion numbers found by CT were more than those by X ray [5(0-21) vs0(0-4) lesions with diameter5-10 mm (P＜0.001),2(0-14) vs0(0-2) lesions with diameter more than 10 mm (P ＜ 0.001),respectively].Patients with positive osteolytic lesions had higher percentage of RB1 gene deletion[46.7％ (14/30) vs 18.8％ (3/16),P ＜0.001],D13s319 deletion [43.3％ (13/30) vs 18.8％ (3/16),P ＜0.001] and high risk cytogenetic abnormalities[50.0％ (15/30) vs 25.0％ (4/16),P ＜ 0.001].Conclusions Chest CT is more sensitive than plain X ray in detecting osteolytic myeloma bone disease.Osteolysis determined by CT is relevant to clinical DS stages and risk stratification of cytogenetic abnormalities.

The regulation of foreign gene expression in Insect-Baculovirus Expression System is very complex. In this report, the effect of 5'-UTR in the expression of hGH gene in cultured Sf9 cells was examined. A 18 bp length in the end of 5'-UTR of hGH (human Growth Hormone, hGH) cDNA including a stem-loop structure was deleted by PCR. The truncated hGH cDNA, delta 1hGH was cloned in pFastBac1, named pFast-Bac-delta 1hGH. After transforming into E. coli. DH10Bac, which have a shuttle vetor-Bacmid, the delta 1hGH was integrated into Bacmid by site-specific transposition, and an expression vector, rBacmid-delta 1hGH DNA was acquired. By transfecting the cultured Sf9 cells with the recombinant expression vector DNA, pure recombinant virus, rAcV-Bac-delta 1hGH was obtained, and hGH gene was expressed. Immuno-blot and Chemiluminescent assay revealed that the expressed hGH had normal immunological activity, the amount of hGH expression level in Sf9 cell supernatant infected with rAcV-Bac-delta 1hGH containing the truncated 5'UTR was four to five times higher than that infected with rAcV-Bac-hGH.

OBJECTIVETo evaluate the exploratory development of bone graft by titanium mesh with bone allograft in treatment of cervical spinal tuberculosis.

METHODSThirty two cases of cervical spinal tuberculosis treated with anterior radical debridement, decompression and inter fixation from January 2002 to January 2007 were included (at least two years follow-up). 18 male and 14 female, age from 18 to 72, mean 41.3 years old. 0.5 - 15.0 months before visit, mean 6.9 months. There were 13 cases in initial treatment group and 19 cases in retreatment group. All cases were divided into two groups (group A and group B) by resource of bone graft. Group A, titanium mesh with bone allograft, 17 cases. Group B, autograft with ilium, 15 cases. Operation time, blood loss, curing conditions, cervical curvature (absolute rotation angle, ARA), function of spinal cord and the rate for bone graft fusions in two groups were compared. The mean follow-up was 3.5 years (range 2 - 5 years).

RESULTSThe primary healing rate of incisions was 93.8% (30/32), and total healing rate was 96.9% (31/32). There were no significant differences in operation time or in blood loss between two groups (P > 0.05). Operation time and blood loss, 72 min/121 ml in group A and 90 min/198 ml in group B, there were significant differences between two groups (P < 0.05). In each group, there were significant differences in the function of spinal cord between preoperative and immediately post operative, between preoperative and follow-up, and between immediately post operative and follow-up (P < 0.05), and there were significant differences in ARA between preoperative and immediately post operative, and between preoperative and follow-up (P < 0.05), and there were no significant differences between immediately post operative and follow-up (P > 0.05). On preoperative, immediately post operative and follow-up, there were no significant differences in the function of spinal cord or in ARA between two groups (P > 0.05).

CONCLUSIONFor cervical spinal tuberculosis followed by effective individual chemotherapy, a good effect can be obtained by treated with radical debridement and bone allograft with titanium mesh.

OBJECTIVETo investigate the association of -141C insert/delete polymorphism with schizophrenia in Wuhan of Hubei province.

METHODSA case-control study was conducted to analyze the polymorphism in the D(2) receptor gene promoter region with schizophrenia. A total of 120 cases of schizophrenia diagnosed according to CCMD-II R criteria and 100 normal controls were recruited in the study.

RESULTSIn this sample, the allele and genotype showed statistically significant differences between patients and normal controls (P<0.05).Especially, the frequency of -141C del was 11% in patients and 18% in control(OR 0.55, 95% CI 0.30-0.96; P<0.05). This allele was less common in schizophrenia than in normal controls (P<0.05).

CONCLUSIONThe -141C del polymorphism is associated with schizophrenia.The polymorphism may modify the association with other factors. Possibly -141C del in the DRD(2) promoter region is a strong candidate for a protective factor for this trait.

Objective To evaluate the development level of public health in Zhejiang Province during China's 12th Five-Year Plan period (from 2011 to 2015)for health policy making in the future. Methods Totally 30 indexes were first summarized into 4 components, including the residents' health level, the allocation of public health resource, the level of public health service and public health security. The evaluation index system was developed by Delphi method. The indicators of 2010 were selected as the baseline for comparison with those corresponding indicators from 2011 to 2015. Each index(the comprehensive development index, the developmental speed, as well as the indicator index)calculated during 12th Five-Year Plan period was evaluated after the targeted indicators were weighed. Results Overall, at a provincial level of Zhejiang, the comprehensive development index was increased from 100 in 2010 to 138.44 in 2015, representing an annual average development speed of 6.72%. The annual average development speed of 13 indexes, ranging from 6.72% to 26.18%, were higher than those in the China's 11th Five-Year Plan period(6.72%); while the annual average development speed of another 17 indexes was lower, with 1 index below zero. However, the number of medical staff per 10000 population(5.23), the treatment success rate among new smear-positive cases (90.76%)and the number of annual outpatient visits in primary hospitals(49.45%)in Zhejiang Province were lower than those in China during the same period(6.39, 92.49%, 56.40%). At a prefectural level, the comprehensive development index fluctuated from 128.65 in Quzhou to 156.35 in Jiaxing and the developmental speed was from 3.90% to 11.26%. These results indicated that the coefficient variant(CV)was 5.76 during China's 12 th Five-year Plan period, which had recorded the historically lowest level since 2010. Conclusion During the China's 12th Five-year Plan period, the development of public health in Zhejiang Province was steadily enhanced. Public health variably developed across 11 prefectures with shrinking gaps. Nevertheless, the number of medical staff per 10 000 population, the treatment success rate among new smear-positive cases and the number of annual outpatient visits in primary hospitals should be improved.

Objective: To investigate the effects of preoperative sarcopenia on postoperative clinical outcome in patients with gastric cancer. Methods: A prospective study was performed in 93 patients with gastric cancer and the skeletal muscle mass was examined by bioelectrical impedance. The primary outcome was postoperative complications. The secondary outcomes were postoperative length of stay, overall hospital costs, 60 days re-admission and mortality rate. Results: A significant difference (sarcopenia group vs. non-sarcopenia group) was observed in the rates of overall postoperative complications, incidence of pleural effusion and intra-abdominal infection, overall hospital stay and postoperative hospital stay (P ＜ 0. 05). The rates of 60 days readmission, 60 days mortality and hospital costs in sarcopenia group were not different between the two groups (P ＞ 0. 05). By univariate and multivariate analysis, preoperative sarcopenia and preoperative nutritional risk are the risk factors of postoperative complications. Conclusion: Sarcopenia is an independent risk factor for postoperative complications in patients with gastric cancer; preoperative patients with sarcopenia have a worse prognosis and should be screened and optimized before surgery.

Objective To explore the factors associated with the complications of cranioplasty, infection and local epidural hematoma, such as age, sex, primary disease, skull defect and concomitant hydrocephalus. Methods 211 patients after cranioplasty were reviewed. Results 8 cases (3.8%) complicated one of them, in which 6 cases with local epidural hematoma and 2 cases with infection. The infection was more likely related with the areas of skull defect (P=0.003). No factor was found related with the local epidural hematoma. Conclusion It is necessary to focus the size of the frontal sinus when repairing the the frontal bone, to avoid the screw into the frontal sinus caused infection.

OBJECTIVETo search for an effective therapy for functional anejaculation (AE).

METHODSFifty-five AE patients were randomized into a treatment group (n = 30) and a control group (n = 25), the former treated with Yangjing Capsule (once 5 pills, tid) and low-dose tadalafil (5 mg, qd alt, 1 h before bedtime), while the latter with oral ephedrine (25 mg before bedtime). Meanwhile, the patients were advised to expose themselves to sexual stimulation, reduce the frequency of sexual intercourses and quit masturbation. The medication lasted 1-3 months, followed by observation of the therapeutic effects.

RESULTSThe total effectiveness rate was 83.34% in the treatment group, 11 cases cured, 8 obviously improved, 6 improved and 5 unimproved, significantly higher than 40.00% in the control group, 4 cases cured, 3 obviously improved, 3 improved and 15 unimproved (P < 0.05).

Suvivin is a novel member of the inhibitor of apoptosis protein (IAP) family, which is known to be over-expressed in various carcinomas and associated with their biologically aggressive characteristics. The aim of this study was to investigate survivin expression in human medullary thyroid carcinoma (MTC) and a MTC cell line TT, correlate suvivin expression with clinicopathologic features of MTC, and test effects of antisurvivin oligonucleotides (ASODNs) on growth and apoptosis of TT cells. Survivin expression was immunohistochemically determined in formalin-fixed and paraffin-embedded specimens obtained from 10 cases of normal thyroid (NT) and 10 cases of MTC, and in TT cells. In TT cells, we confirmed survivin expression and its down-regulation by ASODNs using RT-PCR and Western blot analyses, and investigated effects of ASODNs on viability and growth by MTT assay and apoptosis by apoptotic analyses including DNA laddering assay, acridine orange/ethidium bromide staining and flow cytometric cell cycle analysis. Immunohistochemical analysis showed high survivin expression in MTC and TT cells, whereas no immunoreactivity was detectable in NT. Statistical analyses revealed no significant correlation of survivin expression with the clinicopathologic features of MTC. In TT cells, survivin expression at both mRNA and protein levels was confirmed and could be down-regulated by ASODNs concomitant with decrease in viability and growth, and increase in apoptosis. Our results suggest that survivin plays an important role in MTC independent of the conventional clinicopathologic factors, and ASODNs is a promising survivin-targeted gene therapy for MTC.

OBJECTIVETo analyze the status of HLA-DPA1 and DPB1 matching for unrelated donor-recipient pairs matched at high-resolution allele level for HLA-A, B, C, DRB1 and DQB1 loci.

METHODSA total of 76 unrelated donor-recipient pairs matching at allele level for HLA-A, B, C, DRB1 and DQB1 loci were subjected to HLA-DPA1 and DPB1 sequence-based typing (SBT). HLA-DPA1and DPB1 matching status at high-resolution allelic level was also analyzed.

RESULTSThe allelic identity ratio for single HLA-DPA1 and DPB1 were 17.1% and 9.2%, respectively. HLA-DPA1 and DPB1 allelic identity ratio were both very low. The majority of unrelated donor-recipient pairs (73.7%) had an incompatibility at 1 HLA-DPA1 allele, 9.2% of pairs had an incompatibility at 2 DPA1 alleles. As for the high-polymorphic HLA-DPB1 gene, 57.9% of studied donor-recipient pairs had an incompatibility at 1 HLA-DPB1 allele, almost 1/3 (32.9%) of them were completely incompatible. When HLA-DPA1 and DPB1 genes were analyzed together, the donor-recipient pairs matched at 2/4 was the most common (51.4%), 4/4 allelic complete matched pairs accounted for 5.6%, and 0/4 matched pairs accounted for 8.3%.

CONCLUSIONOur results indicated that the ratio of HLA-DPA1 and DPB1 complete match in the unrelated donor-recipient pairs matching at allelic level for HLA-A, B, C, DRB1 and DQB1 loci were very low. The effect of HLA-DPA1 and DPB1 matching status on clinical unrelated stem cell transplantation still needs to be elucidated.
