Objective To evaluate the significance of selective salpingography(SSG)and fallopian tube recanalization(FTR)in diagnosis and treatment for obstructive infertility.Methods Totally, 268women with infertility caused by obstruction of the fallopian tube were divided randomly into two groups, one (Group A)with a non-operative hysterosalpingeal system by insertion of co-axial cannula and guiding filament made by COOK Corporation in the US and another(Group B)with a self-prepared hysterosalpingeal system modified based on the apparatus of COOK Corporation, for SSG and FTR.Then, efficacy of SSG and FTR for the infertile women was evaluated by one-year cumulative pregnancy rate and reeanalization rate of the fallopian tube.Resnits One hundred and seventy of 198 fallopian tubes were recanalized in Group A, with a recanalization rate of 85.8%, and 290 of 320 tubes in Group B were recanalized.with a recanalization rate of 90.6%.reaching statistically significant difference.Furthermore, recanalization rate varied with different sites of occlusion of the fallopian tube.Pregnancy rate was 35.3%(36/102)in Group A, significantly higher than that in Group B(47.6%, 79/166).As the same, pregnancy rate varied with different sites of occlusion of the fallopian tube.Conclusion Selective salpingography and fallopian tube recanalization with self-prepared hysterosalpingeal system have dual effects on diagnosis and treatment for tubal infertility of women, which are simpler, safer and more reliable, worth to be clinically applied.

Objective To investigate the growth inhibition of human osteosareoma cell line(MG-63) intervened by Hydralazine and 5'-aza-2'-deoxycytidine (5-Aza-CdR),and the effect on the mRNA expression of gene WW domain-containing oxidoreductase (WWOX).Methods Certain volume of 5 × 104/ml of human osteosarcoma cell line MG-63 in logarithmic growth phase were added into 96-well plate.There were Hydralazine group (drug concentration,0.1,1.0,10 μmol/L),5-Aza-CdR group (drug concentration,5,10,20 μmol/L),Hydralazine combined with 5-Aza-CdR group (drug concentration,0.1 μmo/L + 5 μmol/L,1.0 μmol/L + 10 μmol/L,10 μmol/L + 20 μmol/L) and control group (culture medium).Methyl thiazol tetrazolium(MTT) colorimetric methods were used to test the growth inhibition of MG-63 cells intervened by different concentrations of Hydralazine and 5'-aza -2'-deoxycytidine (5-Aza-CdR).Flow cytometry AnnexinV-FITC/PI methods were used to assay the effects of Hydralazine and 5-Aza-CdR inducing apoptosis in osteosarcoma cells in vitro.Real-time polymerase chain reaction (Real-Time PCR)methods were used to detect amplification of WWOX mRNA induced by Hydralazine combined with 5-Aza-CdR or alone.Western-blotting methods were used to examine the expression of WWOX in MG-63 cells.Results Hydralazine and 5-Aza-CdR effectively inhibited the growth of MG-63 cells in a concentration and time-dependent manner.Combined effect was more obvious.Further more the expression levels of WWOX mRNA and protein were increased significantly in combined groups as compared with other groups.Conclusion Hydralazine and 5-Aza-CdR could effectively inhibit the proliferation of MG-63 cells and induce apoptosis which is concurrent with the promotion of the expression of WWOX.The mechanism may be that Hydralazine/5-Aza-CdR effectively cause the demethylated of WWOX gene CpG-rich promoter regions,leading to the high expression of WWOX and inhibit the growth of MG-63 cells.The use of hydralazine in the treatment of osteosarcoma is worthy of further investigation.

Objective To investigate the expression of stathmin and evaluate its influence to anti-microtubule adjuvant chemotherapy in non-small-cell lung cancer(NSCLC).Methods The clinical data and survival status of 78 NSCLC patients were collected,and their paraffin-embedded tissue were detected immunohistochemically with a rabbit anti-human stathmin polyclonal antibody.The clinical significance of stathmin expression and its influence to overall survival rate were analyzed statistically between patients who received paclitaxel or vinblastine adjuvant chemotherapy.Results The positive expression of stathmin could only be observed in the cytoplasm of cancer cells.Among 78 patients,40 (51.3 ％ ) patients were stained stathmin-positive.The positive rate of stathmin was significantly higher in male than female,in central type than peripheral type,in pleura-involved than non-involved,and in dead patients than survival patients ( P ＜ 0.05 ),but showed no significant differences in patients with different age,differentiated grade,pathological type,clinical stage,or lymph-node metastasis status.The expression of stathmin had a significant influence to overall survival rate(x2 =4.348,P ＜0.05 ),and those stathmin-negative patients showed a longer survival time.In stathmin-negative patients,those who received adjuvant chemotherapy with vinblastine exhibited a shorter survival time than those with paclitaxel,but the P =0.06.In stathmin-positive patients,the survival rate or time showed no difference between groups with paclitaxel and vinblastine.The differentiated grade,metastasis to lymph node and expression of stathmin were independent risk factors influencing survival rate.The positive expression of stathmin could only be observed in the cytoplasm of cancer cells.Among 78 patients,40 (51.3 ％ )patients were stained stathminpositive.The positive rate of stathmin was significantly higher in male than female,in central type than peripheral type,in pleura-involved than non-involved,and in dead patients than survival patients ( P ＜ 0.05 ),but showed no significant differences in patients with different age,differentiated grade,pathological type,clinical stage,or lymph-node metastasis status.The expression of stathmin had a significant influence to overall survival rate(x2 =4.348,P ＜ 0.05 ),and those stathmin-negative patients showed a longer survival time.In stathmin-negative patients,those who received adjuvant chemotherapy with vinblastine exhibited a shorter survival time than those with paclitaxel,but the P =0.06.In stathmin-positive patients,the survival rate or time showed no difference between groups with paclitaxel and vinblastine.The differentiated grade,metastasis to lymph node and expression of stathmin were independent risk factors influencing survival rate.Conclusion Our study suggested that the detection of stathmin in resected NSCLC tumor tissues may be helpful for prediction of prognosis,but helpless for making a choice between paclitaxel and vinblastine.NSCLC patients with stathmin-negative,no metastasis to lymph node or good-differentiated grade may have a better prognosis.

Objective To assess the impact of miR-429 on lung adenocarcinoma cell SPC-A1 growth inhibition.Methods Pre-miRTM miR-429 precursor was synthesized and transfected to the SPC-A1 cells by liposome; qRT-PCR assay was used to quantify the miR-429 expression levels; The proliferation of SPC-A1 cells was evaluated by Cell Counting Kit-8 (CCK8).The cell apoptosis was evaluated by Annexin V Assay; The cell cycles of each group were assayed by flow cytometry;Western-blot was used to analyze the expression of cylines.Results The expression level of miR-429 was highly induced after transfection (P ＜ 0.001) ;CCK-8 assay showed the cell proliferation activity of pre-miR-429 group was lower than that of blank and control group 48h and 72 h after transfection(P =0.0167,0.0383,P =0.0320,0.0465),whereas the apoptosis rate had no significant difference between pre-miR-429 and control 24h after transfection by Annexin V Assay(P ＞ 0.05) ; The flow cytometry at 48h after transfection showed that miR-429 decreased the percentage of cells in G1 phase,but increased in S phase,indicating the cell cycle arrest at S phase(P =0.0010,0.0010 ; P =0.0068,0.0133) ; however,the expression level of Cyclin E in pre-miR-429 group had no difference compared with control.Conclusion miR-429 could inhibit cell proliferation and promote cell cycle arrest of lung adenocarcinoma cell SPC-A1.miR-429 may play a potential tumor suppressor role in lung adenocarcinoma cell SPC-A1.

Objective To investigate iodine nutrition and thyroid health status among residents in Zhoushan archipelago, and to analyse their relationship.Methods A total of 3 284 residents in Zhoushan archipelago were surveyed by questionnaire and their thyroids were examined by B-mode ultrasound.The levels of urinary iodine and thyroid function were detected.Results The median level of urinary iodine in 3 284 residents was 226.0 μg/L, being 320.7 μg/L in citizens, 188.9 μg/L in farmers, 122.2 μg/L in salt-makers, 193.6 μg/L in fishers, and 271.7 μg/L in buddhist.The prevalence of diffuse goiter, nodular goiter, colloid goiter, thyroid adenoma, thyroid carcinoma, hyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, and positve rate of TPOAb were 1.7% ,25.3% ,8.7% ,0.2% ,0.4% ,0.5% ,0.8% ,0.03%,1.0% ,and 9.5% repectively.The prevalence of thyroid diseases was increasing with aging, and higher in women than in men (P＜0.05).There was no significant relationship of the thyroid diseases with seafood, smoking,drinking, and tea (P＞0.05).Conclusions The citizens of Zhoushan archipelago have adequate iodine intake.It is pertinent to discuss Universal Salt Iodization.Excessive iodine intake may contribute to the high prevalence rate of thyroid diseases in Zhoushan.

Objective:To evaluate efficacy and safety of multiple-dose tropisetron plus dexamethasone (DXM) versus palonosetron plus DXM for chemotherapy-induced nausea and vomiting. (CINV) in patients received multiple day-based highly emetogenic chemotherapy. Methods:Cancer patients who were receiving multiday-based highly emetogenic chemotherapy were randomly assigned to AB or BA groups. A randomized, cross self-control ed method was applied. Patients in AB group received palonosetron (0.25 mg) 30 min before chemotherapy on day 1 and 3 or additional day 5 in the first cycle;and with tropisetron (5 mg) 30 min before chemotherapy on day 1, 2, and 3, or sup-plementary days (day 4 and 5) in the second cycle. Patients in BA group were treated with tropisetron in the first cycle and with palonosetron in the second cycle. Tropisetron and palonosetron were administered with DXM (10 mg) on day 1, followed by additional doses (5 mg) on days 2 to 5. Palonosetron group comprised patients in the AB group in the first cycle and BA group in the second cycle, whereas tropisetron group included patients in the AB group in the second cycle and BA group in the first cycle. Efficacy and safety of tropisetron versus palonosetron in preventing CINV were evaluated. Results:Ninety-one patients were included in analyses. At day 3, 4, and 5, incidence rates of nausea in the palonosetron group reached 28.6%, 30.8%, and 24.2%, respectively, and those of the tropisetron group totaled 42.8%, 47.3%, and 39.6%, respectively (P<0.05). At day 4, 5, and 6, incidence rates of vomiting in the palonosetron group measured 28.6%, 18.7%, and 5.5%, respectively, and those of the tropisetron group reached 42.9%, 34.1%, and 14.3%, respectively (P<0.05). From day 4 to day 5, day 6 to day 7, and day 1 to day 7, the palonosetron group yielded significantly lower incidence rates of nausea and vomiting than tropisetron group (P<0.05). Rate of rescue treatment in the palonosetron group was lower than that in tropisetron group (13.2%vs. 24.2%, P=0.057). No statistical difference in toxicities was observed between the two groups. Conclusion:Palonosetron plus DXM features better efficacy than that of tropisetron plus DXM against delayed CINV induced by multiple day-based highly emetogenic chemotherapy, which was well tolerated in the two treatments.

Objective Through detecting the expression of triggering receptor expressed on myeloid cells-1 (TREM-1) in pancreas and lung of rats with severe acute panereatitis,to approach the role of TREM-1 in severe actute pancreatitis pathogenesis,and provid a new molecular target for SAP.Methods Thirty healthy male Wistar rat were randomly divided into two groups:control group(group A),n =15 ; severe acute pancreatitis group (group B),n =15.The model of severe acute pancreatitis of rats was induced by retrograde injection of 5％ sodium taurocholate into the pancreatic duct.Results TREM-1 in pancreatic tissues and lung tissues was significantly higher in group B than group A in three time points(6 h,12 h,24 h) and had significant changes(P ＜ 0.05),and had a positive correlation with pancreatic pathology.Conclusion TREM-1 was significantly expressed in severe acute pancreatitis,and aggravated pancreas damage and systemic inflammatory response syndrome.

Objective To describe the effects of surgical intervention on the prognosis in non-small-cell lung cancer patients with pleural carcinomatosis detected at thoracotomy.Methods Retrospectively analyzed clinical data from 54 patients who have unexpected malignant pleural nodules and/or malignant pleural effusions first detected at thoracotomy from January 2009 and December 2013.The effects of surgical intervention on the prognosis were also discussed.Results Sixteen cases had only biopsy,whereas 38 (70.4％) cases had primary tumor resection.The median survival time of 54 patients with pleural carcinomatosis were 23 months.The overall 1 and 5-year survival rates were 64％ and 18％,respectively.Primary tumor resection had significantly better outcome compared with biopsy(MST:respectively,24 vs 15 months,5-year survival rate 39％ vs 6％,P ＜0.05).Univariate analysis showed that primary tumor resection,no smoking history,lower T and N stage has favorable survival(P ＜ 0.05).Multivariate analysis showed that the best N stage(P =0.002) and adenocarcinoma(P =0.035) were favorable prognostic factors in these patients.Conclusion For patients with pleural careinomatosis first detected at thoracotomy,limited primary tumor resection may have survival benefits,lower T and N stage for them was associated with better survival.

Objective:To explore the molecular basis for an individual with Bel subtype of the ABO blood type due to a novel c. 620T>C variant gene, and assess its impact on the structure of GTB transferase.Methods:An individual who had visited the First Affiliated Hospital of Zhengzhou University on February 11, 2023 was selected as the study subject. ABO phenotyping was initially conducted with serological methods, which was followed by direct sequencing of 7 exons of the ABO gene. Subsequently, single-strand sequencing was carried out by using allele-specific primers, and the variant in the B transferase was homology-modeled using the Modeller software. The impact of the variant on the transferase′s spatial structure was analyzed with the PyMOL software. Results:The serological phenotype of the patient was identified as the Bel subtype. Direct sequencing revealed that she has harbored a novel c. 620T>C variant, resulting in a p. Leu207Pro substitution in the polypeptide chain. Combined with single-strand sequencing, her genotype was ultimately determined as ABO* BELnew/ ABO* O.01.02. Three-dimensional protein structure modeling showed that, compared with the wild type, the distance of one hydrogen bond between Proline and Glycine at position 272 has increased, along with disappearance of another hydrogen bond. Conclusion:The novel c. 620T>C (p.Leu207Pro) variant of B allele may affect the structural stability of the glycosyltransferase. The weakened enzyme activity in turn may lead to reduced B antigen expression, manifesting as the Bel subtype by serological analysis.

OBJECTIVETo investigate the feasibility of no nasogastric intubation and early oral feeding at will after thoracolaparoscopic esophagectomy for patients with esophageal cancer.

METHODSBetween January 2013 and January 2014, the feasibility of no nasogastric intubation and early oral feeding at postoperative day(POD) 1 after thoracolaparoscopic esophagectomy was prospectively investigated in 156 patients (trial group) with esophageal cancer in the Henan Cancer Hospital. One hundred and sixty patients previously managed in the same unit who were treated routinely after thoracolaparoscopic esophagectomy were served as control group.

RESULTSOf 156 patients of trial group, 6(3.8%) patients could not take food early as planned because of postoperative complications. The overall complication rate in trial group was 19.2%(30/156), which was 25.0%(30/160) in control group (P=0.217). The anastomotic leakage in trial group and control group was 2.6%(4/156) and 4.3%(7/160) respectively (P=0.380). Compared with control group, time to first flatus [(2.1±0.9) d vs. (3.3±1.1) d, P<0.001], bowel movement [(4.4±1.3) d vs. (6.6±1.0) d, P<0.001] and postoperative hospital stay [(8.3±3.2) d vs. (10.4±3.6) d, P<0.001] were significantly shorter in trial group.

CONCLUSIONSNo nasogastric intubation and early oral feeding postoperatively in patients with thoracolaparoscopic esophagectomy is feasible and safe. This management can shorten postoperative hospital stay and fasten postoperative bowel function recovery.
