Objective To investigate the epidemiological characteristics of multiple-injuries of bone and joint in the belief that a better knowledge of such injuries may help their prevention and treatment. Methods A retrospective study was done on the data of 346 patients with multiple-injuries of bone and joint who had been ad- mitted to our department from January 2001 to December 2004. On the basis of CAI's classification, the following data were statistically analyzed: gender, age, cause of injury, injured part, number of injured parts, associated injuries and mortality. Results Of the 346 injured patients, there were 278 males and 68 females, with an av- erage age of 32.8 years (9months to 89 years). Two hundred and twenty-six cases resulted from traffic accidents, 65 from crush by a heavy object, and 52 from falling. There were 159 fractures of shaft of tibia and fibula, 96 fractures of femoral shaft, 87 fractures of shaft of ulna and radius, 58 fractures of ankle and foot, 57 chest injuries, 50 knee injuries, 50 hip injuries, 49 injuries at the pelvis region, 46 wrist and hand injuries, 36 injuries of shoulder, 36 skull fractures, 33 fractures of humeral shaft, 23 spinal fractures, and 17 elbow injuries. Two hundred and forty-two patients had two parts injured, 83 had three parts, 20 had four parts, and one had six parts. The average number of injured parts was 2.3. Two hundred and five patients suffered from close injuries, and 141 from open ones. The associated injuries included skull and brain injury in 51 cases, chest injury in 23, abdomen injury in five, urine system injury in three, nerve and vessel injury in 21, shock in 78, and fat embolism in six. Five patients died. Conclusions Male young people tend to be the majority of victims of multiple-injuries of bone and joint. Traffic accidents result in most of such injuries. Since multiple-injuries mostly involve lower limbs, they are easy to diagnose while the associated close injuries involving brain, chest, abdomen and pelvic are likely to be overlooked or misdiagnosed. Strengthening safety education and technical training of first aid is important to im- provement of treatment and to decrease of disability rate and mortality.

Objective To estimate the value of transrectal ultrasound/magnetic resonance imaging (TRUS/MR) fusion targeted prostate biopsy(targeted biopsy,TB) in the biopsy naive patients.Methods Between September 2015 and September 2016,91 patients with PI-RADS ≥ 3 suspicious regions on the multiparametric magnetic resonance imaging (mpMRI) were retrospectively evaluated.The age of patients was 46-83 years (median 68).Serum PSA level before biopsy was 1.2-85 ng/ml (median 11.2 ng/ ml),in which 36 cases with PSA ＜ 10 ng/ml,30 cases 10-20 ng/ml,and 25 cases ＞ 20 ng/ml.Two-core TB using real-time virtual sonography (RVS) platform for mpMRI-suspicious lesions was followed by 12-core systematic biopsy (SB).The detection rates for any cancer (PCa) and clinically significant prostate cancer (CsPCa) were compared between TB and SB.Results The total detection rate for PCa was 57.1％,with a comparable positive rate between TB (44.0％) and SB (51.7％) groups which did not significantly differ (P =0.14).The proportion of CsPCa in TB group was higher than that in SB group (80.0％ vs.68.1％,P =0.21).In TB group,detection of PCa for grade 5 lesions was significantly higher than that for grade 3 lesions (77.1％ vs.10.3％,P ＜0.001).Detection of PCa was comparable between TB and SB groups in different regions of PSA ＜ 10 ng/ml,10 ～ 20ng/ml and ＞ 20ng/ml (27.8％ vs.36.1％,50％ vs.56.7％,60％ vs.68％,respectively).Conclusions This study revealed a similar rate of prostate cancer detection between 2-core targeted biopsy guided by TRUS/MR fusion and 12-core random biopsy in different PSA regions for no prior biopsy men.TB maybe tend to detect high proportion of CsPCa.PI-RADS is instructive to select appropriate patients for TB.

0.05),while hyperlactacidemia existed in 21 patients(4.62%).LA levels increased with the creatinine levels,especially in those with Cr more than 90 ?mol/L.However,LA levels increased with the reduction of GFR,especially in those with GFR less than 80 mL/min.It was revealed by correlation analysis that LA level was positively correlated with Cr,ALT and BMI.The optimal cutoff of Cr inducing the lactic acidemia was 95.35 ?mol/L.Conclusion The baseline LA levels of patients with T2DM are similar to those of healthy adults,and LA levels are mainly influenced by BMI and renal and hepatic function.Hyperlactacidemia may be induced when Cr reaches a level more than 95 ?mol/L.

BACKGROUNDAlthough neurologic manifestations often complicate the course of patients with multiple myeloma, direct central nervous system invasion is rare. This study explored the neurologic symptoms, signs, clinical features, therapy and prognosis of Chinese patients with central nervous system myeloma invasion.

METHODSThe diagnosis, therapy and prognosis were analyzed retrospectively in 11 Chinese multiple myeloma patients with central nervous system infiltration from a total of 625 patients who have been treated at Changzheng Hospital (Shanghai, China) between January 1993 and May 2009. Survival curve was constructed with the use of Kaplan-Meier estimates.

RESULTSThere were 11 patients with central nervous system involvement from 625 multiple myeloma patients. The occurrence rate was 1.8%. Ten of the 11 patients had other extramedullary diseases. Symptoms included cerebral symptoms, cranial nerve palsies, and spinal cord or spinal nerve roots symptoms. Cerebrospinal fluid was abnormal in 7 patients, usually exhibiting pleocytosis and elevated protein content, plus positive cytologic findings. Specific magnetic resonance imaging findings suggestive of central nervous system invasion were found in 9 patients. After a median follow-up of 19 months, 3 patients were alive. The median overall survival for all patients was 23 months, while the median overall survival for patients after central nervous system invasion was merely 6 months.

CONCLUSIONSIt is exceedingly rare for there to be central nervous system infiltration in multiple myeloma patients. When it occurs, the prognosis is extremely poor despite the use of aggressive local and systemic treatment including stem cell transplantation.

BACKGROUNDVaspin is a newly-identified adipocytokine related to obesity and insulin sensitivity. However, its pathophysiologic role in humans remains largely unknown. The aim of our study was to investigate the relationship between serum vaspin level and glucose metabolism or obesity in Chinese adults.

METHODSA total of 123 subjects, including 84 subjects with normal glucose tolerance (NGT) and 39 subjects with diabetes, were enrolled in this study. Anthropometric parameters, abdominal fat areas, plasma glucose concentration, serum insulin, lipids, and vaspin level were measured in each participant.

RESULTSSerum vaspin concentration was significantly higher in diabetic patients than that in NGT subjects (592 (438 - 695) pg/ml vs 380 (294 - 517) pg/ml, P = 0.020) in women. In all participants, age, fasting plasma glucose concentration (FPG), 2-hour post-load plasma glucose (PG2h), hemoglobin A1c (HbA1c) and high-density lipoprotein cholesterol (HDL-c) significantly increased from the lower tertile to the higher tertile of vaspin. Univariate linear regression analyses revealed that vaspin level was only positively correlated with age (beta = 0.340, P = 0.002) in NGT subjects. And vaspin was positively associated with FPG (beta = 0.365, P = 0.023), PG2h (beta = 0.526, P = 0.001), HbA1c (beta = 0.388, P = 0.016), and HDL-c (beta = 0.353, P = 0.027), while negatively with homeostasis model assessment of beta cell function (HOMA-beta) (beta = -0.361, P = 0.024) in diabetic patients. In stepwise multivariate regression analyses, age was independently associated with circulating vaspin in NGT subjects, whereas PG2h was an independent predictor of vaspin in diabetic patients. In addition, there was no significant difference of serum vaspin level between men and women. And no significant correlations between vaspin and body fat indexes were detected.

CONCLUSIONSSerum vaspin level is higher in diabetic patients than that in NGT subjects in women. Age predicts serum vaspin level in NGT subjects, while PG2h is independently associated with vaspin in diabetic patients.

Coptidis Rhizoma and Aconiti Kusnezoffii Radix represent hot Chinese medicine and cold Chinese medicine respectively. The purpose of this study is to observe the differentiation effect of Coptidis Rhizoma and Aconiti Kusnezoffii Radix on lewis lung cancer and compare effect of hot Chinese medicine and cold Chinese medicine on tumor progression. In this study, the rat serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix was prepared to treat lewis lung cancer cells in vitro, and effects of the serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix on cell differentiation, proliferation, adhesion, succinic dehydrogenase (SDH) activity and gap-junction intercellular communication (GJIC) were investigated. In vivo, the subcutaneous implant model and pulmonary metastasis model of lewis lung cancer were established. Tumor bearing mice were taken water decoction of coptis chinensis or aconite by intragastric administration bid for four weeks, and the influences of coptis chinensis and aconite on tumor progression were evaluated by body temperature, blood oxygen saturation, red cell ATPase, blood rheology, intratumor hypoxia, capillary permeability and GJIC. The results showed that the serum containing aconite could induce cell differentiation, inhibit cell proliferation and migration, promote SDH activity and GJIC in lewis lung cancer cells. The serum containing Coptidis Rhizoma increased cell adhesion and decreased SDH activity and GJIC without cell differentiation although it also suppressed cell proliferation. Aconiti Kusnezoffii Radix water decoction could keep body temperature, blood oxygen saturation, red cell ATPase and blood rheology, and improve intratumor hypoxia, capillary permeability and GJIC in tumor bearing mice, which led to slower tumor growth and less metastasis. Coptidis Rhizoma water decoction decreased body temperature, blood oxygen saturation, red cell ATPase, blood rheology and GJIC, and promoted intratumor hypoxia and capillary permeability, which resulted to more tumor metastasis although it also prevented tumor growth. These results suggested that the hot Chinese medicine could induce tumor cell differentiation and prevent tumor poison invagination, which is better for tumor treatment than cold Chinese medicine.

OBJECTIVETo investigate the relationship between the clinical features, pathogenesis, immunophenotype, different classification models and prognosis in Chinese patients with diffuse large B-cell lymphoma (DLBCL).

METHODSA total of 147 patients with DLBCL who were treated with CHOP-like or R-CHOP were subjected to analysis. Standard two-step Envision method of immunohistochemical staining was used to assess the expression of CD10, Bcl-6, MUM1, FOXP1, GCET1, CD5, Bcl-2, Ki-67, then according to Hans algorithm, Choi algorithm and Molecular markers, we compared the differences of their prognoses.

RESULTS(1) Kaplan-Meier univariate analysis of the clinical data of 147 DLBCL patients found that the 3-year overall survival (OS) rates were better in early stage (P=0.032), low IPI score (P=0.001), less than one extranodal involvement (P=0.014), and complete remission (P<0.01). The prognoses had no significant difference in terms of gender, age, LDH, B symptoms and treatment options (P value> 0.05). (2 )For Hans model, GCB group had 42 cases, the ABC group 85 cases; GCB were 47 cases, ABC 80 cases (according to Choi model). Choi model suggested GCB subtype showed much better prognosis than ABC subtype (P=0.047), while Hans model shed no statistically significant difference (P=0.285). (3) Ki-67 of 75% was found to significantly discriminate patients with good or bad prognosis. In R-CHOP group at the same time, low Ki-67 (P=0.017) and CD5-negative groups (P=0.012) were better. Cox proportional hazards regression model showed that IPI score (P=0.002) and Ki-67 (P=0.019) were independent adverse prognostic factors.

CONCLUSIONThe Ann Arbor stage, IPI score, extranodal involvement status and Ki-67 were significantly associated with prognosis .Compared to Hans algorithm, Choi had an advantage to predict the different prognosis between subtypes, and ABC group had poor outcome. Finally, both Ki-67 and IPI score were independent adverse prognostic factors.
