The postpartum depression outcome and the effect of psychological intervention were studied in order to reduce the occurrence and development of the postpartum depression. A survey of 4000 women within 4-6 weeks postpartum in 80 communities in Shenzhen, China was performed using random cluster sampling method. By employing Edinburgh Postnatal Depression Scale (EPDS) as a screening tool, the positive women (defined as EPDS ≥10) were randomly divided into intervention group and control group at a ratio of 1:2. The women in the intervention group were treated by means of mailing postpartum depression prevention and treatment knowledge manual, face-to-face counseling, and telephone psychological counseling interventions aiming at individual risk factors, while those in the control group were treated with conventional methods. EPDS scores were assessed in these two groups again at 6th month postpartum. Totally, 3907 valid questionnaires were obtained. All the 771 positive women were divided into two groups: 257 in the intervention group, and 514 in the control group. At 6th month postpartum, the EPDS scores in the intervention group were decreased significantly, from baseline stage (12.84±3.02) to end stage (3.05±2.93), while EPDS scores in the control group were reduced from 12.44±2.78 to 6.94±4.02. There were significant differences in the EPDS scores at end stage between the two groups (t=13.059, P<0.001). Psychological intervention can reduce postpartum depression, with better maternal compliance. It is feasible and necessary to establish postpartum depression screening and psychological intervention model in community-hospital and include the postpartum depression screening, intervention, and follow-up into the conventional healthcare.

Objective To investigate the dynamic changes of serum interleukin(IL)-18,IL-1β and copeptin in acute cerebral infarction(ACI),and analyze the relationship with the serious degree of ACI.Methods The levels of serum IL-18,IL-1β and copeptin were measured by Double-antibody sanduicb enzyme-linked immunosorbent assay(ELISA)in 83 patients with ACI who were admitted to the hospital within 24 h,and neurological impairment were evaluated by European stroke scale(ESS)at the 1st,3rd and 7th day respectively after hospitalization.At the same time,the patients with ACI were compared with 32 normal adults.Results The levels of serum IL-18,IL-1β and copeptin at the 1st,3rd and 7th day after hospitalization were(131.30±31.62),(168.30±28.12),(141.26±24.23)ng/L,(0.35±0.04),(0.82±0.10),(0.52±0.21)μ g/L,and(3.64±0.26),(4.18±0.53),(3.26±2.41)μ g/L respectively.There were significant differences among different times respectively(P＜0.05),furthermore they were higher than those in normal adults[(119.12±27.42)ng/L,(0.21±0.08)μ g/L,(2.63±0.23)μ g/L](P＜0.05).Univariate Logistic regression analysis showed that age,copeptin,IL-18,IL-1β and ESS score was the influencing factor in the serious degree of ACI.There was no significant difference in assessing the serious degree of ACI by receiver operating characteristic(ROC)curve between IL-18 and age,copeptin,IL-1 β,ESS score(P＞0.05).Conclusions The serum levels of IL-18,IL-1β and copeptin are increasing after ACI,indicating that the inflammatory and immune factors may be involved in the development process of ACI.The serum levels of IL-18,IL-1β and copeptin can reflect the serious degree of ACI.

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.

OBJECTIVETo investigate the incidence of lymph node metastasis (LNM) in the right para-tracheal triangle (RPT) of esophageal carcinoma patients and the technique of dissection.

METHODSOn the top of double mediastinal and abdominal lymphadenectomy, 333 esophageal carcinoma patients received RPT lymphadenectomy through the right pleural apical approach from 1990 to 2001.

RESULTSIn these 333 patients, the lymph node metastasis (LNM) rate in the RPT was 36.40%. A total of 457 nodes among 2 159 nodes removed gave a metastasis degree of 24.96%. The LNM rates in RPT for cervical, upper third, middle third, and lower third segments of esophagus were 66.67%, 45.45%, 34.19% and 15.79% (P < 0.05), while their respective metastasis degrees were 44.44%, 27.04%, 24.32% and 18.92% (P > 0.05). The frequency of positive nodes in the RPT for PTI, PT1, PT2, PT3 and PT4 was 0, 17.24%, 28.7%, 45.16% and 53.57%, while those of metastasis degree were 0, 8.77%, 17.62%, 33% and 41.17% (P < 0.01). The frequency of LNM in the RPT in papillary, erosive, patch-like and covert type of early tumor was 40%, 3.85%, 0 and 0 (P < 0.05), while those of the metastasis degree were 29.41%, 1.82%, 0 and 0 (P < 0.01). Higher rate of LNM in progressive stenotic esophageal carcinoma was observed compared with those of the other gross types (56.52%, P < 0.05), so was the degree (P < 0.01). The frequency of LNM in the RPT for mono-focal and multi-focal tumor was 34.98% and 70% without significant difference (P > 0.05), while the degree was 24.29% and 53.33% (P < 0.05). Postoperative complications were: leak (0.6%), and recurrent laryngeal nerve injury (1.2%). No injury of vein or infra-clavicular artery, tracheal damage or mortality occurred.

CONCLUSION1. The lymph node metastasis from esophageal carcinoma has a tendency of wide spread and right para-tracheal triangle is an important region to be doomed. 2. With location, depth of tumor invasion and differentiation of tumor as major factors affecting LNM of esophageal carcinoma, dissection of this region should be paid more emphasis. 3. In early lesions, higher frequency of LNM in the RPT is found in papillary and erosive lesions than in the other macroscopic types. 4. Exposing the RPT, lymph node by dissection through a right pleural apical approach is very important and significant.

Objective: To explore the levels of IL-22 in thymus damaged by γ-ray total body irradiation (TBI), and to study the role of IL-22 in T cell reconstitution after thymic injury induced by TBI. Methods: To induce thymic injury, mice were treated by sub-lethal TBI. Levels of intra-thymic and circulatory IL-22 were detected by using ELISA assay. Untreated mice were used as control. After receiving sub-lethal TBI, mice were intraperitoneally injected with PBS or recombinant mouse IL-22, which were marked as TBI+PBS or TBI+IL-22, respectively. Mice were monitored for counts of total thymic cells and circulatory white blood cells. Flow cytometry was applied to analyze percentages of thymic epithelial cells (TEC), thymocyte subsets and circulatory T cells. Real-time PCR assay was applied to analyze the mRNA expression levels of Foxn1, Ccl25, Aire and Dll4 in thymus. Results: ①Sub-lethal TBI treated mice expressed higher levels of intra-thymic and circulatory IL-22, compared with untreated ones (all P<0.05). ②After injection of recombinant IL-22, TBI+IL-22 mice had higher levels of intra-thymic IL-22 than TBI+PBS mice (all P<0.05). ③On day 14 after irradiation, real-time PCR assay showed that TBI+IL-22 mice had higher mRNA levels of Foxn1, Ccl25, Aire and Dll4 in thymus compared with TBI+PBS ones. Meanwhile, the TBI+IL-22 mice had higher counts of total thymic cells[(5.93±3.19)×10(6)/ml vs (1.42±0.46)×10(6)/ml, t=3.128, P=0.033] and circulatory white blood cells[(3.08±0.94)×10(6)/ml vs (1.43±0.30)×10(6)/ml, t=3.730, P=0.015] than those of TBI+PBS mice. Flow cytometry analysis indicated that TBI+IL-22 mice had higher counts of TEC and thymocytes than TBI+PBS mice on day 14 after irradiation (all P<0.05). On days 7 and 14 after irradiation, TBI+IL-22 mice had higher counts of circulatory white blood cells and T cells than TBI+PBS mice (all P<0.05). Conclusion: Sub-lethal TBI induces upregulation of intra-thymic IL-22, and injecting of recombinant IL-22 increases level of IL-22 in thymus. Injecting of recombinant IL-22 improves recovery of TEC and increases numbers of thymocyte subsets and circulatory T cell after thymic injury.

The purpose of this study is to investigate the preparation of hydroxycamptothecine (HCPT)-loaded cubic crystal liquid embolic precursor solution, and evaluate its in vitro embolic efficiency. Phytantriol was used as cubic crystal liquid embolic material, and the optimal formulation was selected according to ternary phase diagram. Polarized light microscopy, differential scanning calorimetry, and small angle X-ray scattering (SAXS) were used to characterize the cubic crystal structure. High performance liquid chromatography and X-ray diffraction analysis were used to investigate the lactone ring of HCPT. In vitro dissolution was preliminary evaluated, and the simulation embolic model was constructed to evaluate the embolic efficiency of precursor solution. Meanwhile, the gelation time and adhesion force were investigated. The results showed that HCPT-loaded precursor solution for embolization had been successfully prepared with low viscosity which was injectable. The precursor solution could transform into Pn3m structure liquid crystal phase gel rapidly when contracting with excess water. The formed HPCT gel remained its lactone form as the same in precursor solution, and expressed the good ability to block the saline flow, and HCPT could keep sustained releasing drug over 30 days. The prepared drug-loaded embolic precursor solution showed a promising potential for vascular embolization and application in clinical treatment of tumor.

AIMTo compare the influences of wood-cultured Ganoderma lucidum polysaccharides (Gl-PS-WC) and bag-cultured Ganoderma lucidum polysaccharides (Gl-PS-BC) on the proliferation activities of murine spleen lymphocytes in vitro, and investigate whether Gl-PS-BC can be substituted for Gl-PS-WC.

METHODSMixed lymphocyte culture (MLC) reaction, lymphocyte proliferation induced by concanavalin A (Con A, 1 mg.L-1) or lipopolysaccharide (LPS, 5 mg.L-1), MLC reactions inhibited by immunosuppressive drugs, cyclosporine A (CsA, 0.1 mg.L-1), mitomycin (Mit C, 0.1 mg.L-1), or antitumor drug, etoposide (VP-16, 0.1 mg.L-1), were detected in the presence or absence of Gl-PS-WC and Gl-PS-BC in the concentration range of 0.2-12.8 mg.L-1.

RESULTSTwo kinds of polysaccharides were shown to promote MLC in the range of 0.2-12.8 mg.L-1, increase lymphocyte proliferation induced by Con A or LPS and antagonize the inhibitory effects of CsA, Mit C or VP-16 on MLC. No significant difference was observed between these two kinds of polysaccharides in selected concentrations.

CONCLUSIONGl-PS-WC and Gl-PS-BC showed similar effects on the proliferation activities of murine spleen lymphocytes in vitro.

AIM:To explore the changes of plasma levels of soluble vascular endothelial growth factor receptor 2 ( sVEGFR2) and superoxide dismutase ( SOD) in hypertensive patients and hypertensive diabetic patients.METHODS:In this cross-sectional study, 88 cases were enrolled, which were divided into hypertensive group (n=31), hypertensive diabetic group ( n=31 ) and control group ( n=26 ) .Blood pressure was obtained from each participant with mercury sphygmomanometer.The levels of sVEGFR2 and SOD were measured by ELISA.Meanwhile, the levels of plasma glucose, glycosylated hemoglobin A1c ( GHbA1c) and lipid profile were detected.RESULTS:The levels of total cholesterol ( TC) and body mass index (BMI) were significantly higher in hypertensive group than those in control group (P<0.05).The levels of TC, low-density lipoprotein cholesterol ( LDL-C) , triglyceride ( TG) , BMI, waist circumference were significantly higher in hypertensive diabetic group than those in control group (P<0.05).The plasma levels of sVEGFR2 and SOD in both hypertensive diabetic group and hypertensive group were significantly decreased compared with control group ( P<0.05), while the mean plasma levels of sVEGFR2 and SOD in hypertensive diabetic group were significantly decreased compared to the hypertensive group ( P<0.05 ) .A significantly positive correlation between sVEGFR2 and SOD in the whole study population (P<0.05) was observed.CONCLUSION: The plasma level of sVEGFR2 is decreased in both hypertensive and hypertensive diabetic patients, and more significantly decreased in hypertensive diabetic patients.De-creased SOD level may be associated with to the reduction of sVEGFR2.

Objective: : To evaluate the safety and efficacy of an overlapped stenting-assisted coiling technique in treating vertebral artery dissecting aneurysm (VADA) via Low-profile Visualized Intraluminal Support (LVIS) stent-within-Neuroform EZ stent. Methods: : From January 2017 to June 2019, 18 consecutive patients with VADAs (ruptured : unruptured=5 : 13) were treated with the overlapping stents assisted-coiling technique in our center. The overlapping manner was a Neuroform EZ stent being deployed first, followed by LVIS stents placement using the ‘shelf’ technique. The patients’ clinical characteristics, technical feasibility and safety, and immediate and follow-up angiographic results were retrospectively reviewed. Results: : Seventeen (94.4%) procedures were technically successful with an exact deployment of the stents and patent parent or perforator arteries. The immediate angiographies after procedure confirmed Raymond class I, II, and III occlusion of VADAs were in 12 (66.7%), two (11.1%), and four cases (22.2%), respectively. Post-procedural complications developed in one patient (5.6%) with minor brainstem infarctions, which resulted from an in-stent thrombosis during the procedure. Angiographic follow-up at 5.7 months (range 3 to 9 months) demonstrated Raymond class I and II occlusion were in all cases (100%). The modified Rankin Scale scores at 21.3 months (range 15 to 42 months) 0–2 in 17 cases (94.4%) and three in one case (5.6%). Conclusion : Overlapping stents via LVIS stent-within-Neuroform EZ stent combined with coiling is safe and effective for patients with VADA in the midterm results.
