OBJECTIVETo observe the intervention effect of acupuncture on early onset of selec- tive serotonin reuptake inhibitors (SSRIs) in treating depressive disorder, and to study its effect on ser- um 5-HT and unbalanced inflammatory cytokines secreted by TH1/TH2.

METHODSTotally 90 patients with depressive disorder were randomly assigned to the drug control group (as the control group, 45 cases) and the acupuncture combined drug treatment group (as the treatment group, 45 cases). All patients were treated for 4 consecutive weeks. Another 45 healthy subjects were recruited as a healthy control group. The effect of acupuncture on early onset of SSRls in treating acute phase depressive disorder pa- tients was evaluated by HAMD score in the control group and the treatment group before treatment,and at weekends of the 1st, 2nd, and 4th week after treatment. Besides, their serum levels of 5-HT, IL-1β and IL-6 (secreted by TH1), and IL-4 and IL-10 (secreted by TH2) were detected before treatment and after treatment at the weekend of the 4th week.

RESULTSCompared with the healthy control group,serum lev- els of 5-HT, IL-4, and IL-10 decreased in the two drug-treated groups before treatment (P < 0.01); serum levels of IL-1β and IL-6 increased (P <0.01). Compared with before treatment in the same group, HAMD score decreased in the control group at weekends of the 2nd and the 4th week after treatment (P < 0.01); HAMD scores decreased in the treatment group at weekends of the 1st, 2nd, 3rd,and 4th week after treatment (P < 0.01); serum levels of 5-HT, IL-4, and IL-10 increased,serum levels of IL-1β and IL- 6 decreased in the two drug-treated groups after treatment (all P < 0.01). Compared with the control group at the same time point,HAMD scores decreased in the treatment group at weekends of the 1st, 2nd,3rd,and 4th week after treatment (P < 0.01),serum levels of 5-HT, IL-4, and IL-10 increased (P < 0.05, P < 0.01), serum levels of IL-6 decreased (P < 0. 01).

CONCLUSIONAcupuncture could accelerate early onset of SSRIs in treating acute phase depressive disorder, and effectively regulate serum 5-HT levels and inflammatory cytokines secreted by TH1/TH2.

Objective To explore the effect of hydrogen sulfide (H2S) on the expression of survivin in PC12 cells and the neuroprotective function of H2S on PC12 cells.Methods Different concentrations of sodium hydrosulfide (NaHS) were used to treat the PC12 cells at different times.Dose-effect (50-800 μmol/L) and time-effect (0-180 min) on the expression of survivin were evaluated by Western blotting.Cell viability was tested by using cell counter kit-8.Results NariS treatment at the concentrations from 50 to 200 μmol/L for 30 min could up-regulate the expression of survivin in a dose dependent manner,however,when the concentration of NariS was above that,the expression of survivin decreased gradually;when the concentration of NariS reached 800 μmoi/L,the expression level of survivin was lower than the normal level.Treatment with 400 μmol/L NariS within the range of 0-60 min could promote the expression of survivin in a time dependent manner,but with the extension of time,the expression of survivin was declined.On the other hand,400 μmol/L NaHS preconditioning could enhance the expression of survivin promoted by CoCl2 and reduce the injuries of PC12 cells induced by CoCl2 to increase the cell viability.Conclusion H2S increases the expression ofsurvivin in a dose and time dependent manners at certain degree,which may be related to the protection of PC12 cells against chemical hypoxic damage.

OBJECTIVETo study the molecular genetic mechanism and genetic diagnosis of pyruvate dehydrogenase complex deficiency (PHD), and to provide a basis for genetic counseling and prenatal genetic diagnosis of PHD.

METHODSPolymerase chain reaction (PCR) was performed to amplify the 11 exons and exon junction of the PDHA1 gene from a child who was diagnosed with PHD based on clinical characteristics and laboratory examination results. The PCR products were sequenced to determine the mutation. An analysis of amino acid conservation and prediction of protein secondary and tertiary structure were performed using bioinformatic approaches to identify the pathogenicity of the novel mutation.

RESULTSOne novel duplication mutation, c.1111_1158dup48bp, was found in the exon 11 of the PDHA1 gene of the patient. No c.1111_1158dup48bp mutation was detected in the sequencing results from 50 normal controls. The results of protein secondary and tertiary structure prediction showed that the novel mutation c.1111 _1158dup48bp led to the duplication of 16 amino acids residues, serine371 to phenylalanine386, which induced a substantial change in protein secondary and tertiary structure. The conformational change was not detected in the normal controls.

CONCLUSIONSThe novel duplication mutation c.1111_1158dup48bp in the PDHA1 gene is not due to gene polymorphisms but a possible novel pathogenic mutation for PHD.

OBJECTIVETo explore the value of adenosine triphosphate-tumor chemosensitivity assay (ATP-TCA) in individualized treatment of recurrent epithelial ovarian cancer (REOC), and to evaluate the correlation between the in vitro chemosensitivity assay and clinical drug sensitivity.

METHODSSixty-nine REOC specimens were tested by ATP-TCA assay retrospectively. The patients were divided into strong sensitive, moderate sensitively and resistant groups according to the ATP-TCA assay results. The clinical results were evaluated according to imaging and serum CA125 analysis. The correlation between in vitro ATP-TCA assay and clinical outcome was statistically analyzed by χ(2) test. The progression free survival (PFS) and overall survival (OS) of each group were analyzed using Kaplan-Meier method.

RESULTSThe results of ATP-TCA assay had significant correlation with clinical outcome. The clinical chemotherapy outcome became better with increased drug sensitivity in vitro (χ(2) = 9.066, P = 0.004). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate for ATP-TCA method to predict the clinical chemotherapy sensitivity of REOC were 87.5%, 45.9%, 58.3%, 80.9% and 65.2%, respectively. The mean PFS of strong sensitive group, moderately sensitive group and resistant group were 187.1 days, 195.0 days and 60.3 days, respectively. The mean OS were 476.7, 335.7 and 237.5 days, respectively, following the start of TCA-directed therapy. The PFS and OS of the two sensitivity groups in vitro were significantly longer than that of the in vitro-resistant group (P < 0.01).

CONCLUSIONThe results of ATP-TCA assay are well correlated with clinical treatment responses. The assay may be an important and useful method for individualized chemotherapy for recurrent ovarian cancer.

OBJECTIVETo evaluate the expression of BRCA1, ERCC1, TUBB3 and PRR13 mRNA and their relationship with clinical chemosensitivity in primary ovarian cancer, and to assess the predictive value of joint detection of both BRCA1 and ERCC1 genes for the treatment of primary ovarian cancer.

METHODSPrimary epithelial ovarian tumor samples were collected from 46 patients who underwent cytoreductive surgery. Real-time quantitative PCR was used to analyze the relative expression of BRCA1, ERCC1, TUBB3 and PRR13 mRNA in those cases. The correlation of clinical chemosensitivity and the test results was statistically analyzed. The efficacy of the joint prediction of clinical chemosensitivity by combining the two drug resistance gene detection was evaluated.

RESULTSThe BRCA1 mRNA relative expression logarithm in the clinical-resistant group was 0.673±2.143, and clinical-sensitive group -1.436±2.594 (P=0.008). The ERCC1 mRNA relative expression logarithm in the clinical-resistant group was -0.529±1.982 and clinical-sensitive group -3.188±2.601 (P=0.001). BRCA1 and ERCC1 expression level is negatively correlated with platinum-based chemosensitivity. The PRR13 expressions in the two groups were not significantly different (P=0.074), and the TUBB3 expressions between the two groups were also not significantly different (P=0.619). When the intercept point value BRCA1 mRNA expression logarithm was -0.6, the predictive sensitivity, specificity, positive predictive value and negative predictive value were 73.3%, 75.0%, 84.6% and 60.0%, respectively, with the best comprehensive assessment. When the intercept point value of ERCC1 mRNA expression logarithm was -1, the predictive sensitivity, specificity, positive predictive value and negative predictive value were 80.0%, 68.8%, 82.8% and 64.7%, respectively, with the best comprehensive assessment. The combination detection of BRCA1 and ERCC1 can improve the chemotherapeutic sensitivity, specificity, positive predictive value and negative predictive value to 86.7%, 68.8%, 83.9% and 73.3%, respectively.

CONCLUSIONSBRCA1 and ERCC1 mRNA expression has a negative correlation with the clinical sensitivity of platinum-based chemotherapy. Combination detection of the two drug-resistance associated genes can improve the predictive efficacy of ovarian cancer chemosensitivity and beneficial to individual treatment of ovarian cancer.

BACKGROUND: Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure. METHODS: Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively. RESULTS: A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed. CONCLUSION Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.

Objective:To explore the effect of anemarrhena asphodeloside BⅡ (TBⅡ) on the expressions of nuclear transcription factor-κB receptor activator factor ligand （RANKL）, RANK and C-FOS genes during osteoclast differentiation. Method:Molecular docking software LeDock was used to score the docking of TBⅡ with RANKL, RANK and C-FOS. RAW264.7 was treated with soluble RANKL（sRANKL） and divided into control group, sRANKL group (model group), Icariin (Ica) group, low-dose TBIⅡ group (2 μmol·L^-1), medium-dose TBⅡ group (4 μmol·L^-1), and high-dose TBⅡ group (8 μmol·L^-1). The corresponding kit was used to detect iconic enzyme (TRAP) of osteoclast differentiation. Total RNA was extracted by trizol method, Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the expressions of C-FOS, upstream RANKL/RANK and downstream nuclear factor of activated T-cells cytoplasmic 1 (NFATC1), and osteoprotegerin OPG. Result:The molecular docking score were -11.86, -11.38, -12.34 kcal·mol^-1, and there might be multiple binding sites between TBII as well as RANKL, RANK and C-FOS. Compared with the control group, the content of TRAP in model group increased significantly (P<0.01), and compared with model group, the content of TRAP in each administration group decreased significantly (P<0.01), and TBⅡ decreased the content of TRAP in a dose-dependent manner. Compared with the control group, the expressions of RANKL, RANK, C-FOS and NFATC1 increased (P<0.01), whereas the expression of OPG decreased (P<0.01) in model group. Compared with model group, the expressions of RANKL, RANK, C-FOS and NFATC1 decreased (P<0.01), while the expression of OPG increased (P<0.01) in each administration group. Conclusion:TBⅡ may inhibit the differentiation of osteoclast precursors into osteoclasts, inhibit osteoclast activity, reduce bone resorption and improve osteoporosis by regulating RANKL/RANK/C-FOS signal pathway.
