Second primary malignancies are more likely to occur in the multiple myeloma patients .Most of them are Acute myeloid leukemia ( AML) or Myelodysplastic syndrome ( MDS) .The incidence in male or those multiple myeloma patients who is less than 60 years old are more than female or those multiple myeloma patients who are bigger than 60 years old.In recent years,studies of multiple myeloma secondary to leukemia and other tumors are gradually increasing ,but the mechanism and treatment are still unclear .These diseases have the follow-ing characteristics such as progress rapidly ,high mortality rate and low complete remission rate after chemothera-py.

Objective; To study estrogen receptor gene Xbal and Pvu Ⅱ polymorphisms in patients with aggressive periodontitis (AgP). Methods; Xbal and Pvu Ⅱ DNA was extracted by Chelex-100 and amplified by PCR from buccal swabs of 48 cases of AgP patients and 60 normal controls. The PCR products were analyzed by polymerase chain reaction linked fragment length polymorphism (PCR-RFLP) assay. Results: There were significant differences of the distribution of Xba I genotype between AgP group and control group, female AgP group and female control group, male AgP group and male control group(P<0.05). There was no difference of Pvu D genotype distribution between patient group and control group (P>0.05). Multivariate Logistic Regression Analysis showed that male group was less susceptible to AgP than female group(OR =0. 352), the older was less susceptible to AgP than the younger(OR =0.950), and the xxXx genotype was less susceptible to AgP than XX genotype [OR(Xx) =0.224, OR(xx) = 0.678). Conclusion: Specific relationship is found between the susceptibility of AgP and the ER gene-Xbal polymorphism. People with XX genotype is more susceptive to AgP than xx, Xx genotypes.

The genotype and allele frequency distribution were in line with Hardy-Weinberg equilibrium. Conclusion; There is no correlation between CRP + 1059G/C single nucleotide polymorphisms and the susceptibility of chronic periodontitis as well as chronic periodontitis with type2 diabetes.

AIM To study the pharmacodynamics of Baijin Granules [Mallotus apelta (lour.) Muell.Arg.,Smilax china L.],Zhuang medicine,on model rats with sequelae of pelvic inflammatory disease.METHODS The rat model for sequelae of pelvic inflammatory disease was built with mixed bacteria (Escherichia coli and Staphylococcus aureus) and mechanical injury.Subsequently,the rats were randomly divided into eight groups,including model,Baijin Granules low-,middle-,high-dose,positive control (dexamethasone and Huahong Granules),blank control and sham operation groups,with ten rats in each group.After 14 days of successive administration,the hemorheology and blood routine in rats' abdominal aorta were measured by collecting blood in 24 hours of last administration.The pathological morphology of uterine tissue was observed.RESULTS The hemorheology indexes,WBC count and neutrophil percentage were significantly decreased in the model rats,and the pathological morphology of uterine tissue was markedly improved.CONCLUSION Baijin Granules have good therapeutic effects on sequelae of pelvic inflammatory disease in rats.

OBJECTIVE: To investigate the change of diabetic cardiomyopathy in patients with impaired glucose tolerance (IGT) and Type 2 diabetes (T2DM) and its influencing factors. METHODS: Patients with IGT and T2DM were divided into an IGT group (n=314), a T2DM group (n=368) and an NC group (400 normal subjects). The left ventricular ejection fractions (LVEF) and the interventricular septal depth (IVSd) were measured by Doppler echocardiography. The general information and blood biochemistry were also collected during the corresponding time period. RESULTS: Compared with the NC group, waist circumference (WC), bodymass index (BMI), premature family history of cardiovascular disease, the serum levels of fasting plasma glucose (FPG), HbA1c, TC, TG, hyperlipidemia, BUN and Cr significantly increased (P<0.01) in the IGT and T2DM groups. Compared with the NC group and the IGT group, the LVEF significantly decreased (P<0.01) and the IVSd significantly increased (P<0.01) in the T2DM group. The LVEF and IVSd did not have obvious difference between the NC group and the IGT group. Pearson correlation analysis showed a negative correlation between LVEF and HbA1c, TC and duration of disease (P<0.01); but a positive correlation between IVSd and WC, BMI, HbA1c and duration of disease, and a negative correlation between IVSd and HDL (P<0.05). In the multiple linear stepwise regression, HbA1c and duration of disease showed a significant association with both LVEF and IVSd (P<0.05). CONCLUSION T2DM has a close association with cardiomyopathy. HbA1c and duration of disease are the independent predictors for LVEF and IVSd.

OBJECTIVETo study the relationship between endothelial nitric oxide synthase (eNOS) Glu298Asp gene polymorphism and chronic periodontitis (CP) with type 2 diabetes mellitus (T2DM).

METHODSDNA from patients' buccal swabs of CP, CP with T2DM, T2DM and health was isolated and extracted. The eNOS Glu298Asp gene polymorphism were assessed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) respectively.

RESULTSThe distribution of eNOS Glu298Asp genotype in CP group, T2DM group, CP with T2DM group and health group showed statistical differences (chi2 = 18.503, P = 0.005), and the gene frequency showed statistical differences (chi2 = 8.243, P = 0.041). Compared health group to CP with T2DM group, OR value of the genetype T was 0.962, 95% confidence interval lay in between 0.737 to 1.256, which showed T maybe a protective factor. While OR value of the genetype G was 1.043, 95% confidence interval lay in between 0.781 to 1.391, which showed G maybe a risk factor. However, neither T nor G was statistically significant.

CONCLUSIONBased on these findings, there are some association between eNOS Glu298Asp polymorphism and the risk of CP group, T2DM group, CP with T2DM group.

Objectives:To study the feasibility of using ultrasound to evaluate diaphragm function in patients with invasive mechanical ventilation.Methods:From March to December 2017, 40 adult patients with acute respiratory distress syndrome who were admitted to the Department of Critical Care Medicine, Xiangya Hospital, Central South University for more than 48 hours were included. Diaphragmatic excursion and thickness of bilateral anterior, middle and posterior parts were measured by ultrasound for 5 consecutive days.Results:(1) Compared with the diaphragmatic excursion of the right [anterior: (11.05±3.04) mm; middle: (12.08±2.71) mm; posterior: (11.51±3.33) mm] and left [anterior: (13.63±7.52) mm; middle: (15.44±7.52) mm; posterior: (14.76±6.93) mm] sides on day 1, the diaphragmatic excursion of the right [anterior: (8.90±3.65) mm; middle: (10.02±4.24) mm; posterior: (10.25±4.38) mm] and left [anterior: (9.82±1.96) mm; middle: (11.60±1.13) mm; posterior: (11.52±1.98) mm] sides decreased significantly on day 3 ( P<0.05). Bilateral anterior, middle and posterior diaphragmatic excursion recovered on day 5, and was higher than the baseline levels on day 1, with the left middle and posterior diaphragmatic excursion changing most significantly. (2) Compared with day 1, 2, 3, the thickening fraction of bilateral anterior, middle and posterior diaphragm were significantly decreased on day 4, with the left middle part [day 1: (33.87±14.34)%; day 2: (37.26±13.91)%; day 3: (30.56±14.27)%; day 4: (15.53±5.68)%] and the left posterior part [day 1: (35.50±15.69)%; day 2: (39.84±15.32)%; day 3: (29.06±14.96)%; day 4: (13.30±5.79)%] changing most significantly ( P<0.05). The thickening fractions of left anterior, middle and posterior diaphragm recovered on day 5 compared with that on day 4, but still lower than those on day 1 ( P<0.05). Conclusions:It is feasible to evaluate the diaphragm function in patients with invasive mechanical ventilation by ultrasound, which can provide guidance for preventing diaphragmatic atrophy and withdrawing from mechanical ventilation.

BACKGROUNDOver the past two decades, the clinical presentation of renal masses has evolved, where the rising incidence of small renal masses (SRMs) and concomitant minimal invasive treatments have led to noteworthy changes in paradigm of kidney cancer. This study was to perform a proportional meta-analysis of observational studies on perioperative complications and oncological outcomes of partial nephrectomy (PN) and radiofrequency ablation (RFA).

METHODSThe US National Library of Medicine's life science database (Medline) and the Web of Science were exhaustly searched before August 1, 2013. Clinical stage 1 SRMs that were treated with PN or RFA were included, and perioperative complications and oncological outcomes of a total of 9 565 patients were analyzed.

RESULTSPatients who underwent RFA were significantly older (P < 0.001). In the subanalysis of stage T1 tumors, the major complication rate of PN was greater than that of RFA (laparoscopic partial nephrectomy (LPN)/robotic partial nephrectomy (RPN): 7.2%, open partial nephrectomy (OPN): 7.9%, RFA: 3.1%, both P < 0.001). Minor complications occurred more frequently after RFA (RFA: 13.8%, LPN/RPN: 7.5%, OPN: 9.5%, both P < 0.001). By multivariate analysis, the relative risks for minor complications of RFA, compared with LPN and OPN, were 1.7-fold and 1.5-fold greater (both P < 0.01), respectively. Patients treated with RFA had a greater local progression rate than those treated by PN (RFA: 4.6%, LPN/RPN: 1.2%, OPN: 1.9%, both P < 0.001). By multivariate analysis, the local tumor progression for RFA versus LPN/RPN and OPN were 4.5-fold and 3.1-fold greater, respectively (both P < 0.001).

CONCLUSIONSThe current data illustrate that both PN and RFA are viable strategies for the treatment of SRMs. Compared with PN, RFA showed a greater risk of local tumor progression but a lower major complication rate, which is considered better for poor candidates. PN is with no doubt the golden treatment for SRMs, and LPN has been widely accepted as the first option for nephron-sparing surgery by experienced urologists. RFA may be the best option for select patients with significant comorbidity.
