Objective The aim of study is to explore the TORCH infection status on the pre-pregnancy women and analyze the relationship with pregnancy outcome in Hongkou District,Shanghai,and provide the reference for the eugenic and superi-or nurture.Methods Enzyme linked immunosorbent assay (ELISA)was used to detect the specificity antibodies to Toxo-plasma (TOX),Rubelavirus (RUV),Cytomegalovirus (CMV)IgG and IgM in sera of the 3 500 pre-pregnant women in Hongkou District,Shanghai.Chi-square test was used for comparative analysis of the different rates.Results The positive rate of TOX-IgG,TOX-IgM,RV-IgG,CMV-IgG and CMV-IgM in pregnancy women from Hongkou district were 1.37%, 0.34%,89.7%,96.2% and 0.60% respectively.The total positive rate of TOX and (or)CMV IgM was 0.94%.According to age group,the results showed that TORCH infections with three pathogens associated with the pre-pregnancy women’s age,and the difference was statistically significant (χ2=102.9,P<0.01).The abnormal pregnancy rate of TORCH infec-tion-positive pregnancy women (25.0%,3/12)was higher than that of TORCH-negative pregnancy women (6.62%,27/408),and the difference was statistically significant (χ2 =4.43,P=0.04).Conclusion The infection opportunity of TORCH in pregnant women in Shanghai Hongkou district was obviously existent and the TORCH infection status could effect on pregnancy outcome.TORCH testing has important practical significance as a routine examination of the pre-preg-nancy healthy service.

Anatomic hepatic resection not only enables enough tumor-free resection margin,but also guarantee the maximal remnant of normal liver tissue.A 61-year-old male patient with hepatic cancer was admitted to the Affiliated Hospital of Hainan Medical College in February 2012.Multiple space-occupying lesions were found in segment Ⅵ,Ⅶ and Ⅷ by computed tomography (CT).The results of CT volumetry analysis showed that the left hemihepatic volume was lesser than the minimal limit of survival,so anatomic hepatic segmentectomy of Ⅵ,Ⅶ and Ⅷ with preservation of segment Ⅴ was designed to guarantee the maximal remaining of normal liver tissue.Glisson's pedicle transection was used twice to divide the right hemihepatic Glisson's pedicle,segment Ⅵ and Ⅶ Glisson's pedicle,respectivley,then the resection line was determined,and anatomical hepatic segmentectomy of Ⅵ,Ⅶ and Ⅷ was completed.With the procedures adopted,the hepatic ischemia reperfusion injury and hemodynamic instability were maximally reduced during operation.

Objective To study the clinical significance of chromosome karyotyping in pregnant women with a history of abnormal pregnancy. Methods The fetal chromosome karyotypes of 1 193 pregnant women with a history of abnormal pregnancy in Peking University First Hospital from January 4, 2005 to December 31, 2013 were analyzed. According to the etiology of their previous abnormal pregnancy, these women were divided into four groups: 273 women had children with inherited metabolic disorders or single-gene genetic diseases (group A), 81 women had children or fetuses with chromosome abnormalities (group B), eight cases had an abnormal chromosomal karyotype in either husband or wife (group C), and 833 women had abnormal pregnancy of unknown causes(group D). Results Forty-eight [4.0%(48/1 193)] and fetuses were found to have abnormal chromosomal karyotypes, including 26 cases of chromosome polymorphism variations and 22 cases of numerical and structural abnormalities (four cases of trisomy 21, four cases of numerical sex chromosome abnormalities, three cases of trisomy 18, three cases of extra small chromosome mosaicism, three cases of reciprocal translocation, one case of Robertsonian translocation, one case of chromosome six inversion between the arms, one case of chromosome three inversion between the arms, one case of mosaicism of trisomy 14 and one case of structural abnormality of chromosome 14). In group A, four cases (1.5%) of chromosomal abnormalities of clinical significance and four cases of chromosome polymorphism variations were detected. Meanwhile, 61 fetuses with inherited metabolic disorders or single-gene genetic diseases and two cases of gene mutation carriers were detected in group A, but among whom, there were no abnormal chromosome karyotype cases. In group B, two cases (2.5%) of chromosomal abnormalities were found. In group C, two cases (2/8) of reciprocal translocation were found, whose karyotypes were the same as the parents. In group D, three cases of trisomy 21, three cases of trisomy 18, two cases of extra small chromosome mosaicism and two cases of numerical sex chromosome abnormalities were found. All the mothers in this group were of advanced age. Four cases of structural abnormalities and 22 cases of chromosome polymorphism variations were also found in this group, chromosomal analysis was subsequently performed in those couples, and found that the abnormal chromosomal karyotypes in the fetuses were the same as those in the parents. Conclusions Appropriate prenatal cell genetic diagnostic methods should be chosen according to the causes of abnormal pregnancy history.

Professor YU Ren-cun believes that the responsibility of cough and asthma of lung cancer patients not only lies in the lungs, but also relates with spleen, kidney, heart and liver. Treatment should focus on the whole body and overall conditioning. Syndrome can be divided into 4 types: qi deficiency with phlegm resistance, yin deficiency with toxic heat, qi stagnation with blood stasis, and lung and kidney deficiency. Clinical treatment should pay attention to the combination of disease and syndrome, which can achieve satisfactory efficacy.

This article was aimed to study the mechanism of interaction between human serum albumin (HSA) and zinc ions, in order to provide the information on the secondary structure modification of HSA and the thermodynamics parameters using circular dichroism (CD) and isothermal titration calorimetry (ITC). CD and ITC were applied in the study. The concentration of HSA were 0.025 mmol·L-1, 0.05 mmol·L-1, 0.1 mmol·L-1, and 0.2 mmol·L-1, respectively. The concentration of zinc ion was 5 mmol·L-1. The CD analysis revealed that the secondary structure modification of HSA differed depending on the concentration of HAS. And the content ofα-helix was inversely proportional to the concentration of HSA. When the concentration of HSA was 0.2 mmol·L-1, the content ofα-helix was special. A series of thermodynamics parameters including association constants (Kb), stoichiometry (N), entropy (ΔS) and enthalpy (ΔH) were investigated by ITC analysis. And two types of binding sites were observed when ZnSO4(mmol·L-1)?HSA (mmol·L-1)= 5?0.2. The secondary structure modification of HSA interacting with zinc ions depended on the concentration of HSA, a dramatic reduction ofα-helix was detected when the concentration of HSA attained 0.2 mmol·L-1. And the protein hydrophobicity reduction and peptide chains expansion were equally observed at this concentration. The ITC analysis also revealed endothermic and exothermic binding sites in the ZnSO4-HSA interaction when ZnSO4 (mmol·L-1)?HSA (mmol·L-1)= 5?0.2, indicating that the endothermic sites were specific but not preferential for zinc ions interactions. These results provided theoretical supports for the application of Zn2+ to open the endothermic sites of HSA.

Objective To observe the dynamic serological test results of 28 patients with acute brucellosis,and to investigate the relationship between serological test results and diagnosis,curative effect and prognosis of brucellosis.Methods Twenty eight patients(infected with sheep brucellosis) with acute brucellosis in the Department of Brucellosis in Heilongjiang Provincial Land Reclamation Headquarters General Hospital were selected as research subjects,and their serological changes were tested by means of tube agglutination test (SAT)and clinical outcomes were compared before and after each stage of treatment.In addition,symptoms of fever,weakness,sweating,joint pain,swollen lymph nodes and biochemical parameters [alanine aminotransferase (ALT),lactate dehydrogenase (LDH)] were also tested 3,6 and 9 weeks after the treatment.Results Antibody titer reached the peak at the third week,1 ∶ 400(++),which accounted for 39.29％ (11/28); 2857％(8/28) of the patients became negative at the sixth week; 50.00％ (14/28) became negative at the ninth week.Before the treatment,20(71.43％) patients had the symptom of fever,8 (28.57％) patients had the symptom of hyperhidrosis,28 (100.00％) patients had the symptom of joint pain,7(25.00％) patients had the symptom of lymph node enlargement,28 (100.00％) patients' ALT was elevated,and 26(92.86％) patients' LDH was elevated.After three weeks of treatment,except the three patients (10.71％) who occasionally had fever,the rest of the patient's temperature was returned to normal.Also the numbers of patients with the symptoms of fatigue,sweating and joint pain were significantly reduced,and specifically,the conesponding number was 13(46.43％),2(7.14％),and 21 (75.00％)patients,respectively.ALT and LDH returned to normal(only one patient's ALT was out of the range).At the sixth week,all the patients' symptoms of fever and hyperhidrosis disappeared.The number of patients with the symptoms of joint pain and lymph node enlargement reduced to 12(42.86％) and 3(10.71％),respectively.The results of biochemical tests(ALT and LDT) returned to normal.At the ninth week,most patients' clinical symptoms disappeared.A few patients still had the symptoms of weakness[2(7.14％)] and joint piin[6(21.43％)].Conclusions After effective treatment,antibody titer of patients decreases rapidly,at the same time,the clinical symptoms improve quickly.There is a parallel relationship between the change of antibody titer and clinical symptoms.It is demonstrated that the appearing time of brucellosis specific antibodies,the ampfitude and speed of change of antibody titers can be used in diagnosis,therapeutic evaluation and prognosis of the disease.

Objective To observe the clinical features of brucellosis spondylitis and analyse the reasons for its misdiagnosis,and improve the level of diagnosis and differential diagnosis.Methods Forty-two clinically diagnosed patients with brucellosis spondylitis were studied retrospectively,and these patients were diagnosed and hospitalized in the General Hospital of Heilongjiang Land Reclamation Bureau.Their medical records were analyzed,which included the general information,medical history,clinical symptoms,results of magnetic resonance imaging(MRI) and serum tube agglutination test(SAT) and so on.Results Main clinical symptoms and signs were severe persistent neck,back and leg pain.They also had plate shape low back but without kyphosis.In addition,patients had to keep in one posture because their spinal activity was limited.Also,scoliosis or pelvic tilt and lameness may occur when standing,which were typical symptoms of nerve root compression.Thirteen cases were diagnosed as tuberculosis,accounting for 30.95％(13/42); 6 cases were diagnosed as lumbar disc herniation,accounting for 14.28％ (6/42); 2 cases were diagnosed as ankylosing spondylitis,accounting for 4.76％ (2/42).Therefore,the total rate of misdiagnosis was 50％ (21/42).Abnormal MRI signal intensity can be seen in the pathological vertebrae.Specifically,T1-weighted images (T1WI) showed low signal,T2-weighted images (T2WI) showed high signal,or mixed high and low signal intensity was observed.Vertebral showed wedge deformation without collapse and sequestrum; strip and sheet abnormal signal can also be found within the intervertebral disc.Normal structure disappeared and disc space became narrow.Accordingly,the plane dural sac was compressed to form visible abscess near the spine,but psoas abscess was not found.Patients with positive SAT result accounted for 92.85％ (39/42).Conclusion Reasons for misdiagnosis include lack of detailed medical records,atypical clinical symptoms and similar imaging changes and so on.

Objective To investigate clinical features and therapeutic protocols of vulvovaginal-gingival syndrome(VVGS). Methods Clinical data were collected from 11 female patients with VVGS and analyzed. Results Among the 11 patients, the mean and median ages at a definite diagnosis of VVGS were both 46 years, and the average disease duration was 4 years. Painful erosive erythema was found on the vaginal vestibule in 7 patients, on the gingiva in 10, as well as on the bilateral buccal mucosa in 5. Additionally, 8 and 4 patients reported dyspareunia and vaginal hemorrhage, respectively. Seven patients were treated with low-dose oral methylprednisolone combined with hydroxychloroquine or colchicine, and the other 4 were treated with oral hydroxychloroquine alone. Furthermore, all of the 11 patients applied topical tacrolimus 0.1%ointment. Finally, 8 patients were cured or markedly improved. No obvious adverse reactions were observed in any of the patients. Conclusions VVGS mostly occurs in middle-aged women, with the vaginal vestibule and gingiva as predilection sites of painful erythema and dyspareunia as common symptoms. Patients have good responses to methylprednisolone combined with hydroxychloroquine, and hydroxychloroquine alone also shows good efficacy in patients with mild VVGS. Tacrolimus 0.1%ointment can be one of drugs for topical maintenance treatment of VVGS.
