Objective To investigate women's psychological o utcome and its effect factors before and after hysterectomy. Methods In the clinical prospective study, 83 women were investigated for the ir psychiatric status with BDI, HAMD and SCL-90 questionnaires at the time of a dmission and 3 months after hysterectomy. Results The posto perative scales of BDI, HAMD, and SCL-90 were significantly lower than the preo perative ones. The morbidity of depression was decreased from 33.7% to 10.1%. Th e changes of SCL-90 were varied among different age groups. Before hysterectomy , HAMD scales were related negatively to women's educational level, but positiv ely to chief complaints. However, after hysterectomy, HAMD scales were related p ositively to parity, having other physical diseases, but negatively related to p atient's age. Conclusion Hysterectomy is beneficial to wom en's psychiatric and somatic health. Depression occurring before and after hyst erectomy is seen more often in women younger, having more parity, less-educate d, complaining of dysmenorrhea and/or menorrhagia and having other diseases.

Objective To observe the relationship between Toll-like receptor 4 (TLR4) and the sensitivity of PANC1 cells to gemcitabine (GEM),and to analyze the potential mechanism.Methods PANC1 cells were divided into GEM group,lipopolysaccharide (LPS) + GEM group and TLR4-siRNA + GEM group.GEM group was treated by GEM alone.LPS + GEM group was pretreated with 1 mg/L LPS for 4 h and then treated by GEM.TLR4-siRNA + GEM group was transfected with 100 pmol/mL TLR4-siRNA for 4 h and then treated by GEM.The untreated cells were used as the control group.MTT method was used to detect the cell proliferation.Morphological changes and apoptosis rate of the cells were examined by Hoechst33258 staining and flow cytometry,respectively.The protein expression of TLR4,phosphorylated AKT (p-AKT) and activated Caspase-3 were detected by Western blot.Results The median inhibition concentration (ICs0) of GEM in the GEM group,LPS + GEM group and TLR4-siRNA + GEM group was (8.9 ± 0.32),(14.21 ±0.95),(3.96 ± 0.27) mg/L,respectively.The IC50 in LPS + GEM group was significantly higher than that in GEM group (P ＜ 0.01),and the IC50 of GEM in TLR4-siRNA + GEM group was significantly lower than that in GEM group (P ＜0.01).Compared with that in GEM group,the cells with typical apoptotic morphological changes were decreased in LPS + GEM group,which was increased in TLR4-siRNA + GEM group.The apoptotic rate in control group,GEM group,LPS + GEM group,TLR4-siRNA + GEM group was (2.1 ± 0.3) ％,(15.1 ± 2.3) ％,(9.8 ± 1.5) ％,(22.9 ± 3.1) ％,respectively.Compared with that in GEM group,the cells apoptotic rate was significantly reduced in LPS + GEM group (P ＜0.01),which was significantly increased in TLR4-siRNA + GEM group (P ＜0.01).TLR4 protein level in the 4 groups was 0.83 ±0.08,0.81 ±0.07,0.85 ±0.07 and 0.16 ±0.03;p-AKT protein level 0.61 ±0.05,0.36 ±0.03,0.73 ± 0.07 and 0.21 ± 0.02;activated Caspase-3 protein level was 0.66 ± 0.05,0.73 ± 0.07,0.45 ± 0.04 and 0.91 ± 0.07,respectively.The expression of TLR4 and p-AKT in TLR4-siRNA + GEM group was significantly lower than that in GEM group (P ＜0.01),while the expression of activated Caspase-3 protein was increased significantly (P ＜ 0.05).Compared with the GEM group,the expression of p-AKT protein in LPS + GEM group was significantly increased (P＜0.01),and the expression of activated Caspase-3 protein was significantly decreased (P＜0.01).Conclusions TLR4 can inhibit the sensitivity of pancreatic cancer PNAC1 cells to GEM,and the mechanism is related to the activation of PI3K/AKT pathway and downregulation of activated Caspase-3.

Aim To investigate the effects of thrombospondin-1 type Ⅰ repeat antisense RNA on cell proliferation and growth activity of human endothelial cells.Methods The eukaryotic expression vector of pcDNA3.1-/anti-TSP-1-Ⅰ was constructed.Then the vector was transfected into human umbilical vein endothelial cells(HUVECs).The growth activity of endothelial cells after transfection was detected by MTT.The variation of endothelial cell's cycle was determined by flow cytometry.Cell morphological change was observed by transmission electron microscope.Results The eukaryotic expression vector(pcDNA3.1-/anti-TSP-1-Ⅰ)was successfully constructed and transfected into HUVECs.The OD value of pcDNA3.1-/anti-TSP-1-Ⅰ transfective group was promoted compared with that of nontransfective group(P

AIM: To investigate the influences of native and oxidized lipoprotein(a) on human arterial smooth muscle cell (SMC) proliferation, change of intracellular free calcium concentration ([Ca 2+ ] i) and the protective effect of sodium ferulate(SF). METHODS: Lp(a) was oxidized by Cu 2+ and the extent of oxidation was assessed by the MDA content.Human SMC were incubated in culture media with SF for 12 h, then exposed to Lp(a) and oxidized-Lp(a), respectively. MTT colorimetry and flow cytometry were used to evaluated the proliferation of SMC and flurorescent indicator Fura-2/AM was used to determined [Ca 2+ ] i. RESULTS: ox-Lp(a) significantly promoted proliferation of SMC and increased[Ca 2+ ] i compared with Lp(a). SF(40,80 mg/L) remarkedly inhibited SMC proliferation and decreased the rising of [Ca 2+ ] i induced by ox-Lp(a) in a dose-dependent manner, but no effect on SMC proliferation and the increase in [Ca 2+ ] i induced by Lp(a).CONCLUSION: ox-Lp(a) induces the strong growth-promoting effect in SMC through increasing in [Ca 2+ ] i, which might be one of the cellular mechanisms responsible for the higher atherogenic potential of ox-Lp(a) compared with Lp(a), and this process can be prevented by inhibiting of oxidation by SF.

Objective To investigate the risk factors which indicate behavior problems and degree of conflict function defects in different subtypes of attention deficit hyperactivity disorder( ADHD),and to compare behavioral problems,family environment and conflict function in children with and without ADHD.Methods 87children with ADHD and 38 matched controls performed Simon-Stroop task while questionnaires (Parent Symptom Questionnaire and Family environment Scale)were acquired from their parents.Results Questionnaire indicated that children with ADHD-combined(ADHD-C) had the highest score of conduct problem( 1.05 ± 0.44),learning problem ( 1.97 ± 0.52 ),hyperactivity-impulsion ( 1.56 ± 0.60) and hyperactivity index ( 1.45 ± 0.40 ) than ADHDⅠ(0.65±0.32,1.58 ±0.58,1.06 ±0.46,1.01 ±0.31) and matched controls ( 0.42 ±0.24,0.77 ±0.49,0.58±0.40,0.55 ±0.34) in PSQ.ADHD-Ⅰ and ADHD-C had higher score of contradiction(3.28 ± 1.70,4.61 ±2.56 ) and lower score of family cohesion (6.75 ± 2.27,6.61 ± 2.03 ),emotional expression (5.03 ± 1.54,5.06 ±1.91 ),knowledge (3.83 ± 2.30,3.61 ± 1.81 ) and entertainment (3.70 ± 2.12,3.47 ± 2.32 ) than matched controls (2.36 ± 1.44,8.06 ± 1.71,6.03 ± 1.54,4.86 ± 1.91,4.83 ± 2.29) in FES-CV.Behavior data indicated that the correct rate of children with ADHD-Ⅰ and ADHD-C in Simon-incongruent trials( Siin:0.76 ± 0.13,0.69 ±0.13 ) and Stroop-inconsistent trials( Stin:0.82 ± 0.10,0.78 ± 0.08 )were lower and reaction time of children with ADHD-Ⅰ and ADHD-C in the Siin ( (876.4 ± 97.34) ms,( 893.8 ± 130.1 ) ms) and Stin ( ( 864.4 ± 91.82 ) ms,(860.2 ± 125.0) ms) were longer than matched controls ( (Siin (0.81 ± 0.11 ) ms,(810.4 ± 136.1 ) ms; Stin (0.87 ± 0.08 ) ms,(797.4 ± 136.1 ) ms).Pearson correlation analysis suggested that some factors in the FES-CV had correlation with behavioral problems.Conclusion This finding indicates that poor family environment is the risk factor that indicate behavioral problems in children with ADHD and behavioral problems,conflict function defeet of ADHD-C are more serious than ADHD-Ⅰ and matched controls.

Objective To study whether physiological and psychological stresses during parachuting jumps may result in biochemical changes of plasma in parachutists. Method Differences in the levels of hormones (cortisol, growth hormone, insulin, pancreatic glucagon, endothelin, angiotonin I and II, aldosterone), activities of enzymes (superoxide dismutase, glutathione peroxidase, glutathione S transferase), levels of the free radical damage indicator malondialdehyde (MDA), tumor necrosis factor alpha (TNF-α), and the main heat stress protein, HSP70,in the plasma and serum were investigated in control (non-parachuting) and parachuting paratroops. Result Significantly higher levels of serum hormones such as growth hormone, insulin, angiotonin I, renin activities, as well as MDA and plasma TNF-α and HSP70 were observed in the parachuting group. Conclusion Whether these changes can potentially serve as useful biomarkers to assess possible abnormal stress in parachutists and to evaluate the health condition and to select parachutists remains to be further studied.

Objective To explore the correlation of the throid function and malnutrition in maintenance hemodialysis(MHD) patients.Methods Fifty-four MHD patients and 16 normal controls were enrolled as our subjects and named as MHD group and control group.Serum concentrations of total triiodothyronine (TT3),total thyroxine (TT4),free thyroine (FT4),free triiodothyronine (FT3),and thyroid-stimulating hormone (TSH) were measured by enhanced chemiluminescence immunoassay.Their anthropometry,biochemical assays,malnutrition-inflammation score (MlS) and micro-inflammation parameters such as high sensitivity C-reactiveprotein(hs-CRP) were also measured.Results Serum T3,FT3,T4,FT4 concentration in MHD patients were (1.18 ±0.31) nmol/L,(2.61 ±0.62) pmol/L,(100.00 ± 19.96) nmol/L,(8.56 ±0.85) pmol/L respectively,lower than that of control group ((2.95 ± 0.27) nmol/L,(7.12 ± 0.94) pmol/L,(136.25 ± 19.68) nmol/L,(8.89 ± 0.56) pmol/L respectively,P ＜ 0.01).while there was no significant change on TSH (P =0.058).According to albumin nutrient grading standard:the morbidity of malnutrition was 75％ (39/54).The morbidity of malnutrition was 100％ based on the criteria of MIS.Of which,mild malnutrition rate was 29.63％ (16/54),moderate rate for 37.04％ (20/54) and sever rate for 33％ (18/54).The levels of serum creatinine,hemoglobin,serum iron,upper arm circumference,body mass index(BMI),deltoid skinfold,hs-CRP,T3,FT3,T4,FT4,TSH in MHD patients with mild,moderate and serve rate MIS were significant different(P ＜ 0.01).Of 54 MHD patients,32 cases were with micro inflammatory state,accounting for 59.26％ (32/54).There was a positive correlation between FT3 and albumin (P ＜0.01).T3 was related to serum creatinine(P ＜ 0.05).Thyroid function parameters showed a negative correlation with hs-CRP,MIS(P ＜ 0.01).And a negative correlation was seen between nutrition indices and hs-CRP and MIS (P ＜ 0.01).Conclusion Thyroid function can reflect the nutrition status of MHD patients to some degree,and both relate with miro-inflammation.Furthermore,MIS is a useful index for the estimation of malnutrition inflammation status.

Objective:To count and analyze the residue of narcotics for injection after the use in operation rooms in order to find the possibility of risk avoiding and management standardization. Methods:A retrospective research method was adopted to count and analyze 10268 prescriptions including narcotics for injection in operation rooms from June to August in 2014. Results:Ketamine hydro-chloride injection had the largest residue and its remaining amount also occupied the largest proportion of medication. The second one was pethidine hydrochloride injection and the third one was remifentanil hydrochloride for injection. The highest ratio of remaining a-mount in each prescription was ketamine hydrochloride injection, and the second one was morphine hydrochloride injection and pethi-dine hydrochloride injection ranked the third. Conclusion:It is suggested to reduce the specification of medication with the highest ra-tio of remaining amount in each prescription such as ketamine hydrochloride injection, and improve the management efficiency for the use of narcotics in operation rooms.

BACKGROUND: Cervical rotation manipulation is a non-surgical method of cervical spondylosis, showing significant treatment efficacy. But the safety for patients with carotid artery atherosclerosis remains obscure. OBJECTIVE: To analyze the hemodynamic changes of atherosclerotic carotid arteries treated by cervical rotatory manipulation, and to explore the effect of cervical rotatory manipulation on the hemodynamics of atherosclerotic plaque. METHODS: Eight cases of stenosis of ramification of the carotid artery with plaque on MRI. The hemodynamic model of carotid artery atherosclerosis was established, assigned with general boundary conditions and simulated the cervical stretch during cervical rotatory manipulation. All models were grouped and stretched into 0％ (control group), 7％ and 16％ stretch to simulate the hemodynamic changes of atherosclerotic plaque. The hemodynamic parameters, including average wall shear stress, the maximum wall shear stress, the average maximum wall shear stress, the blood velocity of the plaque, and blood flow vectorgraph were compared among groups. RESULTS AND CONCLUSION: (1) All hemodynamic parameters had no significant differences between 7％ stretch and control groups (P＞ 0.05). Compared with the control group, the wall shear stress, the maximum wall shear stress, and the maximum wall shear stress in the 16％ stretch group were significantly increased (P ＜ 0.05), and other indexes showed no significant differences. (2) In summary, different stretches by cervical rotatory manipulation possess different effects on plaque, and a 16％ stretch may affect the hemodynamics of plaque.
