OBJECTIVE:To compare the effectiveness and safety of low-molecular-weight-heparin(LMWH)calcium and rivar-oxaban in preventing lower extremity deep venous thrombosis (DVT) in the elderly patients after surgery of replacement of frac-ture. METHODS:A total of 58 elderly patients underwent hip or artificial femoral head replacement were randomly divided into LMWH group (29 cases) and Rivaroxaban group (29 cases). All patients received basic prevention and physical prevention for DVT after surgery. Based on this,LMWH group was given Heparin calcium injection 4100 IU subcutaneously 10 h after surgery, for 10 d. Rivaroxabar group was given Rivaroxaban tablet 10 mg 10 h after surgery,once a day,for consecutive 10 d. The occur-rence of DVT and positive D-dimer were observed in 2 groups after surgery. The PT,APTT,TT,FIB and platelet counts abnormal-ity were also observed in 2 groups. RESULTS:There was no statistical significance in the incidence of DVT,the occarrence of pos-itive D-dimer,PT,APTT,TT,FIB and platelet counts abnormality 4,10 d after surgery between 2 groups(P>0.05). CONCLU-SIONS:LMWH and rivaroxaban both can be used for lower extremity DVT in the elderly patients after replacement of fracture sur-gery of and have similar therapeutic efficacy and safety.

Objective To investigate the existence of genetic divergence of sympatric populations of Anopheles sinensis of different feeding preferences based on the rDNA-ITS2 sequence differences. Methods A large number of wild anopheles popu-lations were trapped all night by man-baited net and calf-baited net that had been set up between high-density natural villages of An. sinensis populations and vector-breeding sites,from which two groups of An. sinensis were separated by morphological iden-tification and brought back to the lab for conventional breeding. A large closed greenhouse which temperature and humidity was appropriate was selected as research settings of mark-release-recapture methods by female mosquitoes ,in the center of which above An. sinensis populations baited by man and calf and respectively correspondingly marked by red and yellow phosphors were released in together,in each side of which An. sinensis were recaptured simultaneously by man-baited net and calf-baited net. An. sinensis populations trapped by man twice were brought back to the lab and bred with man-blood,correspondingly ones trapped by calf with calf-blood. Man-preferring and calf-preferring strains were screened respectively from An. sinensis which had been baited by man and calf by the mark-release-recapture methods after parent and F1 mosquitoes,and sequencing and aligning of both rDNA-ITS2 were conducted via PCR amplification. Results The recapture ratios of wild parental mosquitoes An. sinensis of man-preferring group by man-baited net and calf-baited net were 54.07%(339/627)and 45.93%(288/627)re-spectively,and ones of calf-preferring group by man-baited net and calf-baited net were 58.01%(409/705)and 41.99%(296/705)respectively. Two groups of parental mosquitoes trended towards selecting the original blood hosts in host-seeking prefer-ence(χ2=19.42,P<0.01). The recapture ratios of F1 mosquitoes An. sinensis of man-preferring group by man-baited net and calf-baited net were 63.43%(765/1 206)and 36.57%(441/1 206),and ones of calf-preferring group by man-baited net and calf-baited net were 68.22%(1 039/1 523)and 31.78%(484/1 523). Two groups of F1 mosquitoes had more significant characteris-tics of selecting the original blood hosts in host-seeking preference(χ2=271.69,P<0.01)and showed the genetic differentia-tion phenomenon,but the results of sequencing and aligning of the rDNA-ITS2 via PCR amplification showed no difference in base sequence between the two strains and both were 469 bp. Conclusions The genetic divergence based on the rDNA-ITS2 se-quence does not happen in An. sinensis sympatric populations of different feeding preferences.

Objective To investigate the application value of solution focused brief therapy in the caring of patients with ulcerative colitis (UC). Methods A total of 180 active UC patients were assigned into control group (90 cases) and observation group (90 cases) using random number table. The two groups were given continuous nursing. For the observation group, the patients received the intervention of solution-focused brief therapy. SF-36 Health Survey (SF-36), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and treatment efficacy rate before and after the interventions were compared between the two groups. Univariate analysis was used to determine the related factors of effective treatment of UC. Results Before the intervention, there was no significant difference in the eight scales of SF-36 between the two groups (P>0.05). After the intervention, the eight scales of SF-36, ie, physical functioning, role limitations due to physical health problems, bodily pain, vitality, general health, social functioning, role limitations due to emotional health problems, and mental health were (70.0±20.9), (72.2± 16.3), (71.9 ± 21.7), (68.7 ± 18.2), (70.4 ± 19.3), (69.5 ± 20.4), (68.9 ± 19.3), (72.6 ± 19.7) points in the observation group, and (62.2 ± 18.7), (66.3 ± 18.8), (65.7 ± 15.2), (62.6 ± 17.4), (62.9 ± 14.9), (63.5 ± 14.6), (61.9±15.2), (64.1±14.5) points in the control group, and there was significant difference between the two groups (t=2.220-3.291, P<0.01). Before the intervention, there was no significant difference in SAS and SDS between the two groups(P>0.05). After the intervention, SASand SDS was (37.3±10.8), (36.8±10.6) points in the observation group and (41.0 ± 11.6), (41.3 ± 12.7) points in the control group, and there was significant difference between the two groups (t=2.215, 2.581, P<0.05) . The efficacy rate was 88.9％(80/90) in the observation group, and 73.3％(66/90) in the control group, and there was significant difference between the two groups (χ2=7.420, P=0.024). Solution focused brief therapy was the related factor of effective treatment in UC patients (χ2=7.107, P=0.008). Conclusions Solution focused brief therapy could improve the quality of life, reduce anxiety and depression, and increase the treatment efficacy in patients with UC, which was an effective intervention method with clinical application value.

Objective To establish cell strain expressing the genes of HIV vpr and mutant HIV vpr-FS, and to explore cell apoptosis ability by HIV Vpr and Vpr-FS. Methods The recombinant plasmids were constructed by cloning HIV vpr and HIV vpr-FS genes into the eukaryotic expression vector pcDNA3.1respectively. To determine the primary structures of HIV vpr and HIV vpr-FS, plasmids were cleaved by restriction enzymes. After the plasmids were transfected into HeLa cells by liposome, the HeLa cells were selected with G418 selective medium, mRNA expression of HIV vpr or HIV vpr-FS of transfected cells was detected by RT-PCR, and Vpr and Vpr-FS protein expression were detected by Western blot assay respectively. The DNA content and the percentage of apoptosis in HeLa HIV vpr cell, HeLa HIV vpr-FS cell and HeLa pcDNA3.1 cell were monitored by flow cytometry and the DNA fragmentation was analyzed by agarose gel electrophoresis. Results BamH Ⅰ and Hind Ⅲ cleavaged products of pcDNA3.1-vpr and pcDNA3.1-vpr-Fincluded 342 bp length fragments suggesting that the length of DNA sequence containing HIV vpr (HIV vpr-FS) within pcDNA3.1 was the same as theoretical length. The HeLa cells transfected by pcDNA3.1-vpr or pcDNA3, l-vpr-FS and selected with G418 could express HIV vpr or HIV vpr-FS by RT-PCR, and express HIV Vpr or HIV Vpr-FS protein by Western blot. The results of flow cytometry and DNA fragmentation showed that there was significant different in the number of apoptotic cells between HeLa HIV vpr cell and HeLa HIV vpr-FS cell, but the difference between HeLa HIV vpr-FS cell and control group was not obvious. Conclusion Recombinant plasmids pcDNA3.1-vpr and pcDNA3. 1-vpr-FS were constructed successfully, and the cell strain expressing HIV Vpr and HIV Vpr-FS proteins was established. The HIV Vpr could induce host cell apoptosis, while the mutant of Vpr did not or weakened this ability. This study provides foundation for further study on HIV vpr gene.

Objective To investigate the clinical characteristics and treatment strategies of arachnoid cyst combined with chronic subdural hematoma.Methods Seventeen patients with arachnoid cyst combined with chronic subdural hematoma,who received treatment in our hospital from February 2008 to March 2016,were chosen in our study;13 of them were performed burr hole irrigation and drainage,2 received craniotomy for removing hematoma and cystectomy,and 2 received endoscopic cyst excision and hematoma removal surgery.A retrospectively analysis of clinical characteristics and treatment strategies of these patients was performed.Results Follow up for 0.5-2 years was performed in the 13 patients performed burr hole irrigation and drainage,and no hematoma relapse was noted;one was found rebleeding in the cyst associated with a small amount of subdural hematoma on the 5th d of surgery,and the subdural hematoma was absorbed during the follow-up observation;one was found that the cyst and subdural hematoma both disappeared in the postoperative check,while the cyst reappeared 40 days after surgery,and during the follow-up observation,the cyst was not enlarged and the chronic subdural hematoma was not relapsed.Two patients recovered after receiving the craniotomy for removing hematoma and cystectomy;two patients recovered after receiving the endoscopic cyst excision andhematoma removal surgery.Conclusion For patients with arachnoid cyst associated with chronic subdural haematoma,burr-hole irrigation and drainage are generally selected;for patients with reappeared cyst or hematoma,there is no need to burr hole again or perform the surgery aiming at the cyst in a haste,and follow-up observation is suggested;for patients whose symptoms in the cyst have appeared before hemorrhage or whose hemorrhage appeared recurrently in the cyst,surgery of hematoma removal and cyst excision can be chosen at the same time.

AIM:We investigated how AT 1-R stimulated by mechanical stresses induces cardiac fibrosis .METHODS:We produced in vivo cardiac pressure overload model in angiotensinogen knockout ( ATG-/-) mice and in vitro mechanically-stretched cell model in cultured neonatal cardiac cells of ATG-/-mice both lack the participation of Ang II .RESULTS: Pressure overload for 4 weeks in ATG-/-mice induced myocardial hypertrophy accompanied by the significant interstitial fibrosis , however , the TGF-β, a key regulatory factor of fibrosis, was not significantly increased in these ATG-/-mice.Meanwhile, the inhibitor for AT1-R significantly inhibited mechani-cal stress-induced cardiac fibrosis in these ATG-/-models whereas inhibition of TGF-βdid not.CONCLUSION:The results showed that mechanical stress-induced fibrotic responses through AT 1-R required the phosphorylation of Smad 2 but not the involvement of TGF-β.

Objective To investigate the correlation between carotid intima-media thickness (CIMT) and left atrial and left ventricular enlargement in patients with acute cerebral infarction. Methods A total of 224 patients with acute cerebral infarction were included. Based on the thickness of CIMT, it was divided into three groups which were normal CIMT group, thickening CIMT group, and carotid plaque (CP) group, with 57, 97, and 70 patients included respectively. Clinical data were collected, and carotid artery color Doppler ultrasound, cardiac color Doppler ultrasound and other examinations were determined to carry out relevant statistical analysis.Results The left anterior-posterior diameter (LAD) , left atrial diameter index (LADI) , left ventricular end-diastolic septal thickness (IVSD) , and left ventricular mass index (LVMI) in the CP group were all higher than those in the normal CIMT group and thickening CIMT group (P < 0.05). The percentage of the left ventricular end-diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) took in the thickening CIMT group were both higher than those in the CP group (P < 0.05). Multi-factor logistic regression analysis indicated that there were statistically significant differences in age, homocysteine and left LVMI (P < 0.05). In the Pearson correlation analysis, CIMT and LADI were positively correlated (r= 0.184, P < 0.01) , and there was a positive correlation between CIMT and LVMI (r = 0.236, P < 0.01). Conclusions Left ventricular enlargement is one of the highrisk factors for CIMT abnormalities in patients with acute cerebral infarction. Left atrial and left ventricular enlargement are closely correlated to the severity of CIMT in patients with acute cerebral infarction, indicating that abnormal CIMT in patients with acute cerebral infarction has a certain predictive effect on left atrial and left ventricular enlargement.

OBJECTIVETo explore the application value of texture analysis of magnetic resonance images (MRI) in predicting the efficacy of neoadjuvant chemoradiotherapy(nCRT) for rectal cancer.

METHODSA total of 34 rectal cancer patients who were hospitalized at Zhejiang Provincial People's Hospital from February 2015 to April 2017 were prospectively enrolled and received 3.0T MRI examination at pre-nCRT (1 day before nCRT), early stage (at 10-day after nCRT) and middle stage (at 20-day after nCRT).

INCLUSION CRITERIAdistance from tumor lower margin to anal edge was less than 12 cm under rectoscope; rectal cancer was confirmed by preoperative pathology; clinical stage was T3 or above; lymph node metastasis existed but without distant metastasis; functions of liver, kidney and heart present no contraindications of operation.

EXCLUSION CRITERIAunfinished nCRT, surgery and three examinations of MRI; image motion artifacts; lack of postoperative pathological results. All the patients underwent rectal cancer long-term three-dimensional radiotherapy and chemotherapy combined with nCRT (oxaliplatin plus capecitabine). The tumor regression grading (TRG) was divided into TRG 0 to 4 grade after nCRT, and TRG 4 was classified as pathological complete remission (pCR); TRG 2 to 3 was classified as partial remission (PR); the rest was no remission (NR). Extraction and analysis of texture features in T2-weighted MR-defined tumor region were performed using Omni Kinetics texture software. The texture values of each time point were statistically analyzed, and the differences of texture values and change differences between pCR and PR+NR, and NR and pCR+PR were compared respectively. Statistically significant texture values were screened and were used in receiver operating characteristic (ROC) curve to assess the prediction of the efficacy of nCRT.

RESULTSOf 34 patients, 21 were males and 13 were females with median age of 49.3 years. Nineteen (55.9%) patients were low rectal adenocarcinoma and 15 (44.1%) patients were middle rectal adenocarcinoma. Nine (26.5%) cases belonged to pCR, 13 (38.2%) belonged to PR, and 12 (35.3%) belonged to NR. Before nCRT, the entropy of tumor area in pCR patients was significantly higher than that in PR+NR patients (7.164±0.272 vs. 6.823±0.309, t=2.925, P=0.006). At the middle stage of nCRT, as compared with PR+NR patients for the texture features of tumor region, the variance (1566±281 vs. 2883±867, t=-4.435, P=0.000) and entropy(5.436±0.934 vs. 6.803±0.577, t=-4.118,P=0.002) of pCR patients were significantly lower; kurtosis(4.800±1.288 vs. 3.206±1.211, t=3.333, P=0.002) and energy (0.016±0.005 vs. 0.010±0.004, t=3.240, P=0.003) of pCR patients were significantly higher. As compared to pCR+PR patients, the kurtosis(2.461±0.931 vs. 4.264±1.205, t=-4.493, P=0.000) and energy (0.011±0.004 vs. 0.014±0.004, t=-3.453, P=0.000) of the NR patients were significantly lower. As for texture change values between early stage and middle stage, the entropy difference was significant between pCR and PR+NR, NR and pCR+PR (1.344±0.819 vs. 0.489±0.319, t=3.047, P=0.014; 0.446±0.213 vs. 0.917±0.677, t=-3.638, P=0.001, respectively). As for texture change values between pre-nCRT and middle stage, variance and entropy differences between pCR and PR+NR (1759±1226 vs. 977±842, t=2.113, P=0.042; 1.728±0.918 vs. 0.524±0.355, t=3.832, P=0.004), and the change values of entropy between NR and pCR+PR (0.475±0.349 vs. 1.044±0.860, t=-2.722, P=0.011) were statistically significant. The above indicators were included in the ROC curve. The results revealed that at the middle stage, entropy value >5.983 indicated the best efficacy for the diagnosis of pCR, with the area under the ROC curve (AUC) of 0.885, the sensitivity of 100%, and the specificity of 66.7%; the energy <0.010 indicated the best AUC for diagnosis of NR was 0.902, with the sensitivity of 91.7% and specificity of 81.8%.

CONCLUSIONSTexture analysis based on T2 weighted images can predict the efficacy of nCRT for rectal cancer. The middle stage of nCRT is the best time of prediction. The entropy and energy of this period are texture parameters having higher predictive ability.
