Objective To study the role of bone turnover markers in multiple myeloma(MM)bone disease.Methods Thirty-eight MM patients were studied.Serum and urine samples were taken before,after 3 months and 6 months therapy.Serum samples of tartrate resistant acid phosphatage isoform-5b(sTRACP-5b),bonespesific alkaline phosphatase(sBAP),osteocslcin(sOC),urine samples of N-telopeptides of type Ⅰ collagen(NTX)were measured.Results Urine NTX concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in pleateum patients and controls.serum TRACP-5b concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in controls.There were no statistical significance compared with pleateum patients.Serum BAP concentrations were significantly lower than that in pleateum patients and controls.Serum OC concentrations were not statistically significant among the newly diagnosed patients,relapsed or refractory patients,pleateum patients and control.In newly diagnosed patients.urine NTX levels were significantly higher in stage Ⅲ than that in stage Ⅰ/Ⅱ,serum BAP levels were significantly lower in stage Ⅲ than that in stage Ⅰ/Ⅱ.There was a positive relationship between urine NTX and serum TRACP-5b in newly diagnosed patients.Urine NTX levels were significantly decreased,and serum BAP levels were significantly increased after 3 cycles effective therapy.There was no change in serum TRACP-5b and OC.Urine NTX and serum TRACP-5b were significantly diseased,serum BAP and OC were significantly increased after 6 cycles of effective therapy.But bone lesions on X-ray did not diminish at that time.Conclusion There is a closely relationship between bone turnover markers and bone lesions in MM.The bone turnover markers may be useful in monitoring MM progress and therapy.

Objective To investigate the clinical feasibility and value of transumbilical single-port laparoscopic cholecystectomy with intra-operative ultrasonic knife for directly handling the cystic artery.Methods A retrospective analysis was performed on the clinical data of 23 1 patients who underwent laparoscopic cholecystectomy with intraoperative ultrasonic knife for directly handling the cystic artery in our depart-ment from March 201 1 to December 2012.According to the required surgical approaches,the patients were divided into transumbilical single-port laparoscopic group (n=125,group A)and three-port laparoscopic group (n=106,group B).The two groups were compared in terms of operative time,intraoperative blood loss,postoperative analgesia,postoperative food intake,length of postoperative hospital stay, and postoperative complications,as well as the performance of the ultrasonic knife in directly handling the cystic artery.Comparison of con-tinuous data between groups was made by t test,while comparison of categorical data was made by chi-square test.Results Group A had a significantly longer mean operative time than group B (20.21 ±1.86 min vs 18.43 ±1.37 min,P<0.05).There was no significant difference in mean intraoperative blood loss between groups A and B (23.23 ±6.25 ml vs 22.34 ±5.49 ml,P>0.05).Group A had sig-nificantly fewer patients who needed postoperative analgesia than group B (5 vs 21,P<0.05).The time to postoperative food intake showed no significant difference between groups A and B (6.56 ±1.23 h vs 6.67 ±1.45 h,P>0.05).The mean length of postoperative hospital stay was (2.98 ±0.23)d in group A,versus (3.02 ±0.18)d in group B (P>0.05).No indwelling drainage tube was used after opera-tion in either group.There were no postoperative bleeding,bile duct injury,bile leakage,incisional wound infection,and other complica-tions in the two groups.The ultrasonic knife had reliable hemostatic effect when directly sealing the cystic artery,without causing postopera-tive secondary bleeding.All patients were followed up for 2-12 months (mean,6.5 months);they recovered well without incisional herni-a,and the umbilical scar was not obvious,with relatively good cosmetic results.Conclusion Transumbilical single -port laparoscopic cholecystectomy has a comparable clinical effect to three-port laparoscopic cholecystectomy,causing little trauma,postoperative pain,and scar,and it is suitable for patients with a high demand for incision appearance.Directly sealing the cystic artery with the ultrasonic knife can reduce bleeding due to careful separation of the cystic artery and shorten the operative time.Therefore,it is a safe,feasible surgical ap-proach and worthy of clinical application.

Objective To detect the genotypes of human papillomaviral infection(HPV)in 970 women who were suspicious as HPV infection, and to investigate its clinical significance. Methods Cervical cast-off cells were acquired with the special cervix brush. DNA hybridization technique was applied to detecting HPV genotypes in 970 clinical specimens. Results Totally 390 case(40.2%) were HPV positive among 970 clinical specimens. A total of 12 subtypes were detected. In 390 cases of HPV infection,260 cases (26.8%) were infected with single HPV subtype, and while 130 cases(13.4%) were with infection of two or above HPV subtypes. HPV6 and 11 were the most frequent low-risk sub-types,and in the high-risk subtypes,HPV16,33,52,58 and 18 were dominant. Conclusion The cervix HPV infection rate is considerable in women in Wuxi area. HPV6 and 11 are the most frequent sub-types. The determination of HPV genotypes plays all important role in early discovery, prevention and treatment of gential tract and cervical cancer.

Objective To evaluate liver protection provided by ulinastatin in rats with liver fibrosis.Methods Fifty pathogen-free male Sprague-Dawley rats,weighing 180-220 g,aged 6-8 weeks,were randomly divided into 5 groups (n =10 each) using a random number table:control group (group C),carbon tetrachloride (CCl4) group,low-dose ulinastatin group (group L),medium-dose ulinastatin group (group M),and high-dose ulinastatin group (group H).Hepatic fibrosis was produced by subcutaneous injection of 50％ CCl4 peanut oil solution two times a week for 8 weeks.After hepatic fibrosis was produced (at 9th week),ulinastatin 2.5× 104,5.0× 104 and 10.0× 104 U/kg were injected via the caudal vein in L,M and H groups,respectively,once a day for 7 days.Blood samples were collected after 24 h of fast on 8th day for determination of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations by ELISA.The rats were then sacrificed and livers were removed for microscopic examination of pathologic changes with light microscope.The expression of interleukin-1β (IL-1β),IL-2,IL-6,IL-8,Toll-like receptor 4 (TLR4),and tumor necrosis factor-alpha (TNF-α) mRNA and protein was detected by RT-PCR and Western blot.Results Compared with group C,the serum AST and ALT concentrations were significantly increased in CCl4,L and M groups,the expression of IL-1β,IL-2,IL-6,IL-8,TLR4 and TNF-α mRNA and protein was up-regulated in CCl4 group,and no significant change was found in the parameters mentioned above in group H.Compared with group CCl4,the serum AST and ALT concentrations were significantly decreased in M and H groups,no significant change was found in the serum AST and ALT conccntrations in group L,and the expression of IL-1β,IL-2,IL-6,IL-8,TLR4 and TNF-α mRNA and protein was down-regulated in group H.The pathologic changes of hepatic tissues were attenuated in M and H groups as compared with group CCl4.The pathologic changes of hepatic tissues were almost recovered to the normal structure in group H.Conclusion Ulinastatin can produce liver protection in rats with liver fibrosis.

0.05).The stimulative index(SI)tested by MTT in MLR at stimulator-to-reactor cell ratio 1∶1,1∶10,1∶20,1∶40 and 1∶80 was 2.7,4.1,3.1,2.5 and 1.6,respectively.The proliferation of T cells stimulated by DCs could be detected at all stimulator-to-reactor ratio.Conclusion DCs could be successfully induced from peripheral blood monocyte in the patients with colorectal cancer by AIM-V serum-free media or by traditional FBS-contained media.AIM-V is more suitable for clinical immunotherapy because it can avoid the risk of allergic reaction for clinical purpose.AIM-V might take the place of serum-contained media to culture DCs.According to the results of MLR,DCs could stimulate allogenetic T cells proliferation at all stimulator-to-effector ratio,furthmore the optimal ratio is 1∶10 .

Objective To study the vascular anatomy for laparoscopic anterior lumbar interbody fusion(LALIF),and to evaluate the feasibility of the surgical approach.Methods Vascular anatomy of 36 adult human bodies were studied by infusing red latex into the arteries.They were classified according to the percentage of the exposed lumbosacral disc in the interiliac triangle.Results The mean height of the aortic bifurcation(AB)was(41.81?13.82)mm,and the height of the confluence of the common iliac vein(CCIV)was(20.22?14.20)mm.The angles of the AB and CCIV were(51.88?12.09)? and(77.08?20.98)? respectively.The width of the median sacral artery(MSA)were(1.57?0.42)mm and(1.33?0.50)mm respectively at the top and bottom of the lumbosacral disc.While the distance from the right iliac vessel(RIV)to MSA at the top and bottom of the lumbosacral disc were(20.83?7.73)mm and(27.60?7.80)mm.The average width of the exposed disc was(36.78?13.06)mm,which accounts for(72.29?25.64)% of that of the disc.According to our morphological classification,22 specimens(61.1%)belong to type Ⅰ(Standard type,being exposed by more than 65%),9(25.0%)type Ⅱ(Narrow type,being exposed by 45% to 65%),and 5(13.9%)type Ⅲ(Barrier type,being exposed by less than 45%).The height of CCIV was negatively,but not significantly,correlate to its angle(r=-0.287,P=0.089).Conclusions In 86.1% of our patients,anterior approach is a safe and effective way for laparoscopic interbody fusion.Moreover,in 61.1% of the patients,the procedure can be carried out without managing the iliac vessels arround the interiliac triangle.

Objective To explore the clinical value of lymphocyte sub-population and NK levels in patients with primary lung malignant tumor and patients with chronic obstructive pulmonary disease (COPD). Methods The percentage of CD3 +,CD4 +, CD8 +, CD19 + and NK cells were measured in 60 COPD patients and 50 primary lung malignant tumor patients and 40 normal control subjects using alkaline phosphatase antialkaline phosphatase (APAAP) assay, and CD4 +/CD8 + ratio was calculated. Results The levels of CD3 +,CD4 +,CD4 +/CD8 + and CD19 + cells were significantly lower in the patients with primary lung malignant tumor or COPD than those in the normal control subjects, which CD8 level was significantly higher (P0.05). No difference in the levels of CD3 +, CD4 + and CD8 + cells was found between the primary lung malignant tumor and COPD patients, but NK and CD19 + cells levels had significant difference(P

BACKGROUND:Comparative study results between the efficacies of traditional Chinese medicine (TCM) therapy with Western medicine therapy in the treatment of knee osteoarthritis remain controversial. Currently, meta-analysis studies mainly focuson comparison of the efficacy between TCM and Western medicine,butlack investigations among TCM therapies. Itmakes usdifficult tofulyunderstand the efficacy of TCM therapy for knee osteoarthritis.
OBJECTIVE:To compare the efficacies of TCM therapy with intra-articular injection of hyaluronic acid for knee osteoarthritis using a networkMeta-analysis method.
METHODS:PubMed, The Cochrane Library (tissue 10, 2015), EMbase, CNKI, CBM, VIP, Wangfang databaseswere searchedup to October 20, 2015forrelevantrandomized controled trialsaddressingthe efficacies of TCM therapyversusintra-articular injection of hyaluronic acid for knee osteoarthritis. Two reviewers independently selected the studies, extracted information, and assessed the quality of included trials. Data extraction from eligible studies was pooled and meta-analyzed using Stata12.0 and WinBUGS1.4.3softwares. Odd ratios with their 95% confidence interval were estimated as effect size between treatments.
RESULTS AND CONCLUSION:A total of 59 randomized controled trials involving 6 155 patients with knee osteoarthritis and 12 treatment strategies were included. The results of network meta-analysis showed that TCM comprehensive therapy wassuperior to the TCM monotherapy and intra-articular injection of hyaluronic acid. Among thesetherapies, the efficacy of needle scalpel combined with acupuncture is optimal. TCM comprehensive therapies may be the best choice to treat patients with knee osteoarthritisofKelgren-LawrenceII-III. Morelarge-scaleand wel-designedrandomized controled trials are stil warranted due to the limitation of the present study.

BACKGROUND:Autologous bone marrow mesenchymal stem cels (BMSCs) transplantation has been used for clinical treatment of dilated cardiomyopathy. But the efficacy and safety of autologous BMSCs transplantation remains controversial. OBJECTIVE: To systematicaly assess the efficacy and safety of autologous BMSCs transplantation for treatment of dilated cardiomyopathy by using meta-analysis approach. METHODS:PubMed, Cochrane Library (Issue 2, 2016), Embase, CNKI, CBM, VIP, WanFang were systemicaly searched for relevant randomized controled trials (RCTs) about autologous BMSCs transplantation and conventional drugs for the treatment of dilated cardiomyopathy. After information extracting and quality assessing, Meta-analysis of left ventricular ejection fraction, left ventricular end-diastolic diameter, 6-minute walking distance, percentage of myocardial perfusion defect, mortality, incidence of malignant arrhythmia events and heart transplantation rate during treatment and folow-up was performed using R3.1.0 software. RESULTS AND CONCLUSION:A total of 7 RCTs involving 341 patients were included. Meta-analysis results showed that for efficacy, compared with the conventional drugs, BMSCs can increase the left ventricular ejection fraction [1 month post-treatment: mean difference (MD)=3.02, 95% confidence interval (CI) (1.55, 4.49); 3 months post-treatment:MD=4.38, 95%CI(3.55, 5.52); 6 months post-treatment:MD=6.47, 95%CI(4.78, 8.15);≥ 12 months post-treatment:MD=8.23, 95%CI(5.15, 9.19)]; decrease the left ventricular end-diastolic diameter after 3 months [3 months post-treatment:MD=-0.65, 95%CI(-0.72,-0.59); 6 months post-treatment:MD=-0.12, 95%CI(-0.21,-0.03);≥ 12 months post-treatment:MD=-0.19, 95%CI(-0.24,-0.13)]; increase 6-minute walking distance after 6 months [6 months post-treatment:MD=87.70, 95%CI(51.55, 123.85);≥ 12 months post-treatment:MD=143.83, 95%CI(122.73, 164.93)]; and decrease percentage of myocardial perfusion defect at 3 months [MD=-3.56, 95%CI(-5.57,-1.55)]. For safety, BMSCs can decrease the mortality [risk ratio=0.46, 95%CI(0.24, 0.89)], but there is no significant difference in the incidence of malignant arrhythmia events and heart transplantation rate between two treatment groups. To conclude, these results indicate that BMSCs transplantation for dilated cardiomyopathy is one of effective and safe treatments.

Background and purpose:The role of urine N-telopeptides of type Ⅰ collagen(uNTX) and serum bone spesifi c alkaline phosphatase(sBAP)was confi rmed in osseous metastasis of solid tumors. The aim of this article was to study their role in multiple myeloma (MM). Methods:Thirty eight MM patients (22 new diagnosed, 12 relapsed or refractory, 4 plateau patients ) were examined. Ten age-matched healthy volunteers were used as controls. Urine and serum samples were taken from all patients and controls before therapy, after 3 months and 6 months chemotherapy. Urine samples of NTX, serum samples of BAP were measured with enzyme-linked immunosorbent assays (ELISA). Results:Urine NTX concentrations were signifi cantly higher in newly diagnosed and relapsed or refractory patients than that in plateau patients and controls. Serum BAP concentrations were signifi cantly lower than that in plateau patients and controls. In newly diagnosed patients, urine NTX values were signifi cantly higher in stage Ⅲ disease than in stage Ⅰ/Ⅱdisease, serum BAP values were signifi cantly higher in stage Ⅰ/Ⅱ disease than stage Ⅲ disease. At the third month, urine NTX were signifi cantly lower and serum BAP were signifi cantly higher as well as at the sixth month. But osteolytic lesions in X–ray had no change at the sixth month. Conclusions:Bone turnover markers uNTX, sBAP and bone destruction are closely interrelated in multiple myeloma, they change much earlier than X-ray. They are useful in monitoring progression and the therapeutic effect of myeloma.
