OBJECTIVETo study the possible relationship between tumor necrosis factor (TNF)-alpha-238G/A gene polymorphism and the susceptibility to intrauterine HBV infection.

METHODSTwo hundred and fifty-six children, including 130 infants born to HBsAg positive mothers were divided into two groups: forty-five children with intrauterine HBV infection (group I) and 85 children without intrauterine HBV infection (group II), with a control group of 126. TNF-alpha-238G/A gene polymorphism was examined in all 256 children, by means of real-time quantitative fluorescent PCR.

RESULTSA significant difference of TNF-alpha-238A allele frequency was found between group I and group II (x2=6.797, P=0.009), and between group I and the controls group (x2=0.047, P=0.002), but there was no significant difference between group II and the control groups (x2=0.047, p=0.828).

CONCLUSIONThis study found that genetic polymorphism of tumor necrosis factor-a was associated with intrauterine HBV infection

Objective To discuss the treatment of ureteropelvic junction obstruction by laparoscopic pyeloplasty. Methods A retrospective review of consecutive laparoscopic pyeloplasty in 102 patients between September 2001 and December 2007 was performed. The ureterpelvic junction was dissected and the obstruction portion was excised. Anastomosis was then performed through the ureter and the renal pelvis walls with a stent. Results The mean operating time was 120 min and the average blood loss was 80ml. No major complication occurred intraoperative. The drainage was removed in 3-10 days. The average hospital stay was 8.5 days. The stent was kept for 30-60 days. IVU and B ultrasound examination revealed that the hydronephrosis alleviated during the follow-up and no anastomosis stricture occurred. Conclusions Laparoscopic dismembered pyeloplasty could provide lower morbidity, shorter hospital stay, and faster convalescence. It could be an effective treatment for ureteropelvic junction obstruction.

OBJECTIVETo explore the susceptibility of children to develop intrauterine hepatitis B virus (HBV) infection through studying the association between interferon gamma (IFN-gamma) + 874 single nucleotide polymorphism (SNP) and intrauterine HBV infection.

METHODSThe subjects were selected from outpatients who were in our hepatitis B (HB) vaccine following-up clinics. The subjects whose mothers were HBV carriers were inoculated with HB vaccine or HB vaccine and hepatitis B immunoglobulin (HBIg). Intrauterine HBV infection was defined as peripheral blood HBsAg and/or HBV-DNA positive at birth and lasting for six months (group I). Normal immune children were defined as peripheral blood negative for HBV marker since birth and afterwards HBsAb titers were above protective level (group II). The subjects were composed of the following two groups. Group I consisted of 46 children with intrauterine HBV infection. Group II was composed of 73 normal children. A Taqman fluorescence polymerase chain reaction for the IFN-gamma + 874 SNP was performed for both groups.

RESULTSIFN-gamma + 874 SNP was tested successfully for every subject. Frequencies of AA, AT and TT genotype were 67.4%, 19.6% and 13.0% in the intrauterine HBV infection group, and 45.2%, 30.1% and 24.7% in the normal immune children group. A significant difference was found in the frequency distribution of IFN-gamma + 874 genotype between the two groups (chi(2) = 5.102, P = 0.02389). In the intrauterine HBV infection group the AA genotype was more common than in normal immune group.

CONCLUSIONThere is an association between IFN-gamma + 874 SNP and intrauterine HBV infection. This study suggested the possibility that IFN-gamma + 874 SNP might be important in determining an individual's susceptibility to development of intrauterine HBV infection.

Objective:To analyze the law of distant metastasis in patients with small lung adenocarcinoma with different CT findings, and to explore the feasibility of different preoperative examination methods for small lung adenocarcinoma with different imaging characteristics.Methods:Clinicopathological data of cT1a-cN0 lung adenocarcinoma patients admitted to the respiratory center of China-Japan Hospital from January 2017 to December 2018 were retrospectively collected. A total number of 785 patients were included, including 289 males and 496 females. SPSS 22.0 was used for statistical analysis.Results:A total number of 785 patients were included in this study, including 287 pure ground-glass nodule (GGN) patients, 111 GGN predominant patients, 221 solid predominant patients and 166 solid nodule patients. Among the included patients, 8 had distant metastasis, including 6 with bone metastasis, 1 with brain metastasis and 1 with brain and adrenal metastasis. No distant metastasis was observed in the patients with pure GGN and GGN predominant nodule, while 1 solid predominant patients had distant metastasis, and 7 patients with solid nodules had distant metastasis. The probability of distant metastasis was 0.5% for the solid predominant patients and 4.2% for the solid nodule patients. Univariate analysis results showed that CEA level ( P=0.030), the largest diameter of the lung window tumor ( P=0.003), the largest diameter of the solid component of the lung window tumor ( P<0.001), the largest area of the lung window tumor ( P=0.002), mediastinal window tumor maximum area ( P<0.001), CTR ( P<0.001), TDR ( P<0.001), and pleural indentation sign ( P=0.037) were risk factors for distant metastases. Multivariate analysis showed that CEA ( OR=1.019, 95% CI: 1.002-1.037, P=0.028) and TDR ( OR=0.000, 95% CI: 0.000-0.310, P=0.001) were independent risk factors of distant metastasis. Conclusion:For patients with pure GGN and GGN predominant nodule, preoperative examination could not be required, but for pure solid nodules, it is necessary to perform relevant preoperative examination including skull MRI before surgery to exclude distant metastasis.

OBJECTIVETo explore the possible relationship between cytokines (TNF-alpha, IFN-gamma, IL-4 and IL-10), which were expressed abnormal quantity in the peripheral blood to intrauterine HBV infectious children, gene single nucleotide polymorphism (SNP) and susceptibility to HBV intrauterine infection.

METHODSA cross sectional study on molecular epidemiology was carried out. The subjects were selected from outpatients of the hepatitis B vaccine special clinics of our hospital. According to intrant criteria, children under high risk of HBV intrauterine infection were divided into immuno-failure group (group I) and immuno-effective group (group II) while children without high risk were included in the control group. Four gene SNP sites of TNF-alpha-238, IFN-gamma + 874, IL-4-590 and IL-10-1082 region were determined by real-time quantitative fluorescent PCR.

RESULTSSignificant differences of TNF-alpha-238 A allele frequency were found between group I and group II (chi(2) = 6.797, P < 0.05) as well as between group I and control group (chi(2) = 9.513, P < 0.05). No evident difference of TNF-alpha-238 A was found between group II and control group (chi(2) = 0.047, P > 0.05). Significant differences of IFN-gamma + 874 A allele frequency were found between group I and group II (chi(2) = 7.238, P < 0.05), and between group I and the controls (chi(2) = 5.199, P < 0.05) but no significant difference was found between group II and control group (chi(2) = 0.602, P > 0.05). Significant differences of IL-4-590 C/T allele frequency were not found between group I and group II (chi(2) = 0.632, P > 0.05), group I and control group (chi(2) = 0.584, P > 0.05), or between group II and control group (chi(2) = 0.004, P > 0.05) respectively. Significant differences of IL-10-1082 G allele frequency were found between group II and group I (chi(2) = 10.359, P < 0.001), and between group II and the controls (chi(2) = 35.418, P < 0.001), but not found between group I and control group (chi(2) = 1.759, P > 0.05).

CONCLUSIONThis study suggested the possibility that TNF-alpha-238 A allele and IFN-gamma + 874 A allele were associated with HBV intrauterine infection. There was no evident relationship between IL-4-590 C/T allele SNP and susceptibility to HBV intrauterine infection, but the IL-10-1082 G allele seemed to be associated with preventive efficacy to HBV intrauterine infection.

BACKGROUNDThe influences of genomic background are confirmed in more diseases. Immunologic tolerance after intrauterine infection of hepatitis B virus is considered to occur in T cells. Cytokines work effectively in eliminating virus by immune system after hepatitis B virus infection. To explore the relationship between cytokines (tumor necrosis factor-alpha, interferon-gamma, interleukin-4 and interleukin-10), which expressed abnormal quantity in the peripheral blood to intrauterine hepatitis B virus infectious children, gene single nucleotide polymorphism (SNP) and susceptibility to hepatitis B virus intrauterine infection.

METHODSThis is a cross sectional study of molecular clinical epidemiology. The subjects in this study were selected from outpatients of hepatitis B vaccine follow-up special clinics of our hospital in the period. According to intrant criteria, the high risk children of hepatitis B virus (HBV) intrauterine infection were divided into immune failure group (group I); and immune effective group (group II) and non high risk children belonged to the control group. Four gene SNP sites of TNF-alpha -238, IFN-gamma +874, IL-4 -590 and IL-10 -1082 were determined by real-time quantitative fluorescent polymerase chain reaction (PCR).

To compare the diagnostic value between the thyroid imaging reporting and data system ( TIRADS) and ultrasound ( US ) patterns of 2015 American Thyroid Association ( ATA ) guidelines in the differentiation of benign and malignant thyroid nodules. 639 patients in Jiangsu province who were scheduled for ultrasound-guided fine-needle aspiration biopsy or thyroidectomy were recruited for the retrospective study. All of them were categorized based on TIRADS and ultrasound patterns of ATA ( 2015 ) guidelines. The receiver operating characteristic curve was established to assess and compare the diagnostic value of the two models. Results:( 1 ) 639 patients with 847 thyroid nodules were included in this study, 510 females and 129 males. The mean age was (46. 77 ±12.98)yearsold. (2)818nodulescouldbeclassifiedaccordingtoTIRADS. ThemalignancyratesofTIRADS2,3, 4A, 4B, 5 were 0, 15. 9%, 49. 1%, 78. 8% ,and 100%, respectively. (3) Ultrasound patterns of ATA could be assigned to 793 nodules. The malignancy rates of nodules with very low, low, intermediate, high suspicion for malignancy were 6. 2%, 10. 3%, 24. 9% and 70. 1%, respectively. (4) Ultrasound patterns of ATA had higher specificity (77. 9%) compared to TIRADS. The sensitivity and area under curve of ultrasound patterns of ATA were lower than those of TIRADS, though, not significant. Ultrasound patterns of ATA(2015) guidelines may yield higher specificity in the differential diagnosis of benign and malignant thyroid nodules, while TIRADS classification may offer a relatively higher sensitivity and area under curve.

OBJECTIVETo evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of complex anal fistula.

METHODSThe preoperative digital examination and MRI with the phased-array coil were implemented for 28 patients who were clinically suspected with complex anal fistula. The final diagnosis were based on surgical findings. Outcomes of MRI and digital examination were compared with surgical results.

RESULTSTwenty-five patients were diagnosed as complex anal fistula, 1 presacral cyst and 2 chronic anorectal fistula combined with perianal mucinous adenocarcinoma. All the patients were correctly diagnosed by MRI,while the patients with presacral cyst and perianal mucinous adenocarcinoma could not be diagnosed correctly by digital examination. According to the Parks classification, 3 patients were suffered from trans-sphincteric fistula, 10 intersphincteric, 5 supra- sphincteric and 7 extra-sphincteric. The diagnosis rates of the internal opening with digital examination and MRI were 48% and 84%, the rates of the primary tract were 76% and 100%, and the rates of the secondary extensions were 57.9% and 94.7% respectively. The differences in detection of internal opening, primary tract and secondary extensions between MRI and digital examination were significant (P<0.01).

CONCLUSIONMRI with the phased-array coil can correctly orient the internal opening and direction of the complex anal fistula, and find the relationship between anorectal sphincters and the complex fistula.

OBJECTIVETo evaluate the technique and clinical outcomes of modified transperitoneal laparoscopic radical prostatectomy.

METHODSA total of 105 patients received the operation with age ranging from 51 to 73 years from January 2008 to June 2010. Mean level of serum prostate specific antigen was 13.6 µg/L and mean prostatic volume was 45 ml. Pathological studies of biopsy confirmed the prostate carcinoma with Gleason score 6-8. Radionuclide bone scan revealed no metastasis. Based on previously retroperitoneal radical prostatectomy, modified technique was applied involving surgical approach, bladder neck dissection and vesicourethral anastomosis.

RESULTSMean operative time was 93 min (65 - 150 min). Intraoperative blood loss was 115 ml (50 - 400 ml). No complication of bowl injury occurred. Positive surgical margin was present in 24 patients. Normal continence were seen in 64 patients after catheter removed. Recovery of incontinence within 3 months was seen in 33 patients and 3 to 12 months in 5 patients respectively. Three patients with incontinence were still in the follow-up.

CONCLUSIONSTransperitoneal laparoscopic radical prostatectomy provides large working space and clear anatomic exposure. Higher efficiency and lower complication rate are obtained through modified laparoscopic technique involving seminal vesicle isolation, bladder neck dissection and vesicourethral anastomosis.
