[Objective] To investigate the occurrence rate, manifestations and influencing factors of emotional disorder in patients after acute stroke. [Methods] Emotional disorder in 107 cases of acute stroke was assessed by 17-item Hamilton Depression Scales (HAMD), 14-item Hamilton Anxiety Scales (KAMA), Mini-Mental State Examination (MMSE) and Barthel index (BI), and the relationship between emotional disorder and influencing factors were also analyzed. [Results] The occurrence rate of emotional disorder after acute stroke was 41.12% , in which depression was 18.69% , anxiety 9.35% and concurrence of depression and anxiety 13.08% . Emotional disorder usually occurred in the dominant hemisphere of young patients with lower BI after repeated attacks of stroke; its manifestations relieved with the cure of primary diseases. Its dominant syndrome pattern was classified as stagnation of liver-Qi. [ Conclusion ] Emotional disorder, possibly being a stress reaction, is the common complications of acute stroke and usually classified as stagnation of liver-Qi; early effective rehabilitation is the best preventive method for emotional disorder acute stroke.

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 explore the impact of intervention of weight management (WM)on readmission rate of patients with congestive heart failure(CHF).Methods sixty-six CHF patients were divided into the control group(34 cases)and the intervention group(32 cases).The patients in the intervention group received the weight management intervention for 6 months after discharge,while the control group was carried on the conventional education and follow-up.The ability of WM and readmission rate of patients due to onset of CHF were compared between the two groups.Results Six months after the intervention,significant differences were found on the scores of weight monitoring,WM related-knowledge,belief and practice in the intervention group,but only WM related-practice was improved in the control group.The readmission rote due to onset of CHF was reduced in the intervention group.Conclusions WM intervention could significantly improve the ability of WM and reduce readmission rate due to CHF onset of CHF patients.

OBJECTIVE:To study the mechanism of Aurantii fructus immaturus(AFI)and its main active ingredients in pro-moting gastrointestinal motility of model rats with spleen deficiency. METHODS:170 rats were randomly divided into blank group (10 rats) and modeling group (160 rats),rats in modeling group was induced models with spleen deficiency by bitter cold diar-rhea+irregular diet. After modeling, rats were randomly divided into model group, naringin (NA) low-dose, medium-lose, high-dose groups(3.267,6.535,13.070 mg/mL),neohesperidin(NE)low-dose,medium-lose,high-dose groups(3.865,7.730, 15.460 mg/mL),synephrine(SY)low-dose,medium-lose,high-dose groups(0.252,0.504,1.008 mg/mL),compatibility groups with 3 monomer ingredients (NA-NE-SY) low-dose,medium-lose,high-dose and AFI water decoction low-dose,medium-lose, high-dose groups(0.104,0.208,0.416 g/mL,calculated by crude drug),ig,once a day,10 mL/kg,for 7 d. After the last admin-istration,gastrin (GAS) in serum,and acetylcholine (ACh),motilin (MTL),substance P (SP),vasoactive intestinal peptide (VIP)levels in plasma were detected. RESULTS:Compared with blank group,GAS level in serum and ACh,MTL,SP levels in plasma in model group were reduced(P<0.01),VIP level in plasma was increased(P<0.05). Compared with model group,ex-cept for the GAS level in serum showed no obvious change in NA high-dose group and SY doses groups,other medicine groups were obviously increased (P<0.05 or P<0.01);the ACh levels in serum were obviouly increased in NE high-dose group,SY high-dose group and AFI water decoction low-dose group(P<0.01). MTL levels in plasma were obviously increased in NE medi-um-dose,high-dose groups,SY high-dose group,compatibility low-dose,medium-dose groups and AFI water decoction medi-um-dose,high-lose groups (P<0.05);SP levels in plasma were obviously increased in NA low-dose,medium-dose groups and NE doses groups(P<0.05 or P<0.01);VIP levels were reduced in NA low-dose group,SY high-dose group and AFI water decoc-tion low-dose,medium-lose groups(P<0.05). CONCLUSIONS:AFI may promote the gastrointestinal motility of model rats with spleen deficiency by promoting the secretion of GAS,ACh,MTL,and inhibiting the secretion of VIP;there are differences be-tween AFI and the 3 monomer ingredients in regulation of gastrointestinal hormones.

Objective To analyze hemolysin and virulence -related genes in incomplete hemolytic Staphylococcus aureus.Methods Fifty strains of incomplete hemolytic Staphylococcus aureus were isolated from patients admitted in the Second Affiliated Hospital of Soochow University during 2013 and 2014, and the isolates with complete hemolytic phenotype were also collected at the same period as the control strains . All the strains were inoculated and subcultured on four kinds of sheep blood agar plates supplied by different manufacturers to compare their hemolytic phenotype .The relative mRNA expressions of hemolysin genes (hla, hlb, hlc, hld) in standard strain, complete and incomplete hemolytic phenotype strains were detected by real-time quantitative polymerase chain reaction (RT-qPCR), and valued by 2 -△△Ct method.t test was used to compare mRNA expressions of hemolysin genes .Western blot was performed to analyze the expression of α-hemolysin.Antibiotic susceptibility test of incomplete hemolytic strains was performed using broth microdilution method.Resistant gene mecA and virulence genes pvl, tst were detected by PCR.Results The steady and hereditary incomplete hemolysis was observed in 50 strains of incomplete hemolytic Staphylococcus aureus on the sheep blood agar plates from different suppliers .Taking mRNA expression of hla, hlb, hlc, hld in standard strain as 1, the relative mRNA expressions of hemolysin genes in incomplete hemolytic strains were 0.02, 7.51, 0.06 and 0.12 respectively, there were statistical differences between standard strain and incomplete hemolytic strains (t =8.46, -56.40, 8.12 and 7.61, all P <0.05).And the expression of α-hemolysin was decreased in incomplete hemolytic strains .All the strains were identified as methicillin resistant Staphylococcus aureus (MRSA).Three strains exhibited different minimum inhibitory concentrations of teicoplanin and linezolid after subcultured , but the differences had no impact on the final results of antibiotic susceptibility test .mecA, pvl and tst genes were positive in incomplete hemolytic strains . Conclusion Staphylococcus aureus with incomplete hemolytic phenotype is methicillin resistant with higher expression of β-hemolysin and lower expressions of α-hemolysin, γ-hemolysin and δ-hemolysin.It carries plv and tst virulence genes and is of high virulence .

The craniospinal radiotherapy method was studied by using the whole body positioning frame and base dose plan compensation (BDPC) technique.11 patients with central nervous system malignancies in our hospital were studied. Use whole body positioning frame with the head - neck shoulder and body membrane to immobilize posture, then use BDPC for the intensity-modulated radiotherapy. Target area conformability index(CI), homogeneity index (HI), dose of endangerment organ (OAR) and beam connecting dose distribution are evaluated. The use of base-dose-compensation intensity-modulated plan combined with whole-body positioning technology improves the target area conformability and target uniformity, simplifies the design of craniospinal radiotherapy, improves the placement accuracy and ensure good placement repeatability. We measure beam connecting dose distribution. Cold and hot spots do not appear, and calculated values are basically identical. The application of whole-body positioning technique combined with BDPC optimization method in the treatment of the craniospinal radiotherapy meets the clinical requirements of dosimetry. Moreover, it is simple and can improve the treatment planning efficiency.

Objective To explore the CTV to PTV external expansion boundary and the effect of the dose of normal lung tissue under different fixed modes by a comparative analysis of combined body position and thermoplastic film fixed set-up error of radiation therapy for lung cancer. Methods From October 2016 to March 2018, the patients who received chest radiology at the Tangshan people's hospital were enrolled as subjects retrospectively divided into two groups, including 50 patients with lung cancer radiotherapy with combined body position fixation, and 40 patients with lung cancer with thermoplastic film fixation. The two groups of patients drew the target areas in accordance with the unified standard, and the set-up error of left and right, up and down, front and rear ( x, y, z axis) were recorded respectively after 1 time/week cone CT( CBCT) matched with the planned CT image and analyzed by t test. According to the MPTV =2. 5Σ+0. 7δ, CTV to PTV external expansion boundary in the combined body position group were calculated. And the V5、V20 and V30 of two groups of patients were calculated and analyzed by TPS system. Results The set-up error of the combined body position group and thermoplastic film group were respectively (1. 00 ± 0. 58) mm and (3. 28 ± 0. 43) mm on the x axis, (1. 42 ± 0. 28) mm on the y axis and (4. 03 ± 0. 41) mm, (1. 06 ± 0. 44) mm and (3. 18 ± 0. 34) mm on the z axis. The set-up errors of the two groups were statistically significant on x, y and z axis( t= -20. 740, -35. 596, -25. 015,P<0. 05). There was no significant difference in set-up errors between the central and peripheral lung cancer patients and between left and right lung cancer patients(P>0. 05). Through the MPTV =2. 5Σ+0. 7δ, CTV to PTV external expansion boundary in the combined body position fixation group was 2. 906 , 3. 746 and 2. 958 mm on x, y and z axis respectively. The comparison between group A and B showed that the mean values of V5 , V20 and V30 in group B were reduced by 1. 5％, 3. 1％ and 4. 8％ respectively compared with group A. Conclusions The combined body position technique can improve the accuracy of lung cancer patients after radiation therapy,and further reduce the boundary of CTV to PTV, which is of certain value to reduce the occurrence of radiation pneumonitis.

OBJECTIVE: To assess the value of next generation sequencing (NGS) for the prevention and control of thalassemia. METHODS: NGS was used to sequence 3083 clinical blood samples suspected for thalassemia during initial screening. Retrospective analysis was conducted on blood samples detected with rare genotypes of thalassemia and abnormal hemoglobin. RESULTS: NGS analysis of the 3083 samples has found 1089 subjects with thalassemia genotypes (alpha-thelassemia genotype: 26.01%, beta-thalassemia genotype: 6.71%, and alpha-compound-beta genotype: 2.59%), which yielded a positive detection rate of 35.32%. Rare alpha-thalassemia genotypes including HBA2 c.123delG, HBA1 c.354_355insATC and Fusion gene, and rare beta-thalassemia genotypes including HBB c.-100G>A and HBB c.316-90A>G, were discovered. In addition, 19 patients were found to have abnormal hemoglobin, mainly including Hb Hamilton, Hb Hekinan II, Hb Shizuoka, Hb Owari, Hb New York, Hb J-Bangkok and Hb Port Phillip. CONCLUSION NGS can play a crucial role for improving of the prevention and control of thalassemia and formulating a screening system with better efficacy.
