Objective To study the risk factors of obstetrical brachial plexus palsy (OBPP).Methods Forty-six newborn infants with OBPP were recruited between January 1997 and December 2009 from Technical Appraisement Center for Medical Malpractice of Shandong province as OBPP group.In the control group,138 newborn infants delivered in the same time,same hospital and same gender were collected,with a ratio of 1:3.All the cases were analyzed retrospectively.The newborn,maternal,childbirth data and working experience of midwives were analyzed by univariate and multivariate logistic regression analysis.Results ( 1 ) External pelvimetries of the two groups were normal.All were singleton newborns by vaginal deliveries with cephalic presentation.Twenty-two newborns had left unilateral palsies,and the other 24 had right unilateral palsies.The numbers of the whole,upper and fore arm type were 17,26 and 3,respectively.The maternal age,gravidity,parity and gestational weeks were higher in OBPP group than in the control group ( P ＜ 0.05 ).( 2 ) The maternal antepartum body mass index ( BMI ) [ ( 29.5 ± 2.4 ) kg/m2 ],height of the uterus [ (34.9 ± 2.4) cm ] and abdominal circumference [ ( 105 ± 6) cm ] in OBPP group were higher than those in the control group [ ( 26.1 ± 2.5 ) kg/m2,( 33.7 ± 2.2 ) cm and ( 99 ± 5 ) cm,respectively ] ( P ＜ 0.05 ).The newborn birth weight in OBPP group [ ( 4390 ± 489 ) g ] was significantly higher than the control group [ ( 3404 ± 360 ) g] ( P ＜ 0.01 ).The working experience of midwives in OBPP group [ ( 5.2 ± 2.3 ) years ] was less than the control group [ ( 8.9 ± 5.4) years ] ( P ＜ 0.01 ).(3) There was a higher proportion of instrumental delivery ( 28.3％ vs.3.6％ ),uterine atony (28.3％ vs.6.5％ ),prolonged second stage(8.7％ vs.0.7％ ) and fetal malposition( 10.9％ vs.2.9％ ) in the OBPP group than in the control group ( P ＜ 0.05 ).(4) Univariate logistic analysis showed that the P values of maternal age,antepartum BMI,height of uterus,abdominal circumference,newborn birth weight,gravidity,second stage duration,instrumental delivery,fetal malposition,uterine atony and working experience of midwives were all less than 0.10.And the working experience of midwives was a protective factor.(5)The factors listed above were taken as variables,selected stepwise regression for multivariate logistic regression analysis.Boundary value was 0.10.It showed that the antepartum BMI ( OR =1.733 ) and newborn birth weight ( OR =1.004 ) were related to OBPP ( P ＜ 0.10 ).The significance of maternal antepartum BMI was higher than birth weight.Conclusions The maternal antepartum BMI is the most important risk factor for OBPP,and the newborn birth weight is the other risk factor.The working experience of midwives is a protective factor.

Angiotensin (Ang Ⅱ),a main effector peptide of the renin-angiotensin system (RAS),mediates a hormonal action in the maintenance of blood pressure and electrolyte levels,and thus fluid homeostasis.Recent studies have implicated that it correlates with tumor growth,angiogenesis,metastasis and it has drawn more and more attention.Many studies show that Ang Ⅱ-AT1R/AT2R play crucial roles in tumor growth,metastasis,invasion and tumor angiogenesis,which are formed new targets for treating malignant tumors.

Objective To explore the diagnosis value of X-ray breast imaging reporting and data system (BI-RADS) combined with wire-guided localization biopsy for breast microcalcifications in impalpable breast cancer.Methods 192 palpation negative patients with 205 microcalcification lesions were detected by mammography.All lesions were classified according to BI-RADS descriptors for calcification and were categorized by the BI-RADS.The patients with BI-RADS category 4a and above underwent X-ray positioning guide wire-guided biopsy and pathological diagnosis.Results In 205 microcalcification lesions,74 (36.1％) were malignant lesions,131 (63.9 ％) were less than benign lesions.The positive predictive value of malignant breast lesions in clustered,segmental,regional linear branching calcifications were higher [83.3 ％ (5/6),100.0 ％ (11/11),100.0 ％ (1/1)],followed by clustered,linear,segmental,regional pleomorphic calcifications [55.9 ％ (38/68),50.0 ％ (1/2),40.0 ％ (8/20) and 33.3 ％ (4/12),respectively].The positive predictive values of malignant in linear branching calcifications and pleomorphic calcifications were significantly higher than those of coarse heterogeneous calcifications,amorphous or indistinct calcifications (x2 values were 34.44,51.87,16.71,29.86,all P ＜ 0.05).The linear branching calcification had the highest possibility.The proportions of malignant lesions in four different types of glands were extremely dense 40.5 ％ (30/74),heterogeneously dense 39.2 ％ (29/74),scattered areas of fibroglandular density 10.8 ％ (8/74) and fat 9.5 ％ (7/74),respectively.Conclusions BI-RADS categorization for breast microcalcification lesions can improve the detection rate of impalpable breast cancer.Linear branching calcification has higher predictive value for malignant lesions.Dense breast is the risk factors of breast cancer,which should be attached great importance.

Objective To assess the effects of absorbable biomedical membrane-embedded intrauterine device ( IUD) in prevention of recurrence after hysteroscopic adhesiolysis for severe intrauterine adhesions ( IUA ) .Methods A prospective study was carried out among 125 patients who underwent hysteroscopic adhesiolysis for severe IUA from February 2013 to January 2015.Foley catheter was placed immediately after surgery and removed 7 days later.Then patients were randomly divided into three groups:group A (40 cases) received round IUD insertion after catheter removal;froup B (41 cases) received IUD placement and intrauterine injection of sodium hyaluronate; group C ( 44 cases ) received absorbable biomedical membrane-embedded IUD insertion.All patients received two artificial cycles ( oral estradiol valerate, 9 mg/d) the first day after surgery.Hysteroscopy was carried out two months later to assess the repair of endometrium.Patients who were cured or whose condition was greatly improved received three-dimensional transvaginal ultrasound examination in the first natural cycle.Thickness of endometrium, uterine volume and blood flow index were compared.Results Cure rate and effective rate in group C were significantly higher than that in groups B and A [43%(19/44) vs.22%(9/41) and 20%(8/40), χ2 =6.89,P=0.03, 86%(37/44) vs.56%(26/41) and 65%(23/40), χ2 =9.78, P =0.01].The improvement rate of menstruation was higher in group C compared with groups B and A [84%(37/44) vs. 63%(26/41)and 58%(23/40),χ2 =7.73, P=0.02].Average endometrium thickness, uterine volume and blood flow index were also significantly improved in Group C[(8.4 ±1.1) vs.(7.2 ±1.5) and (7.6 ± 1.1) mm, F=5.42,P=0.01,(4.3 ±0.3) vs.(3.9 ±0.4) and (4.0 ±0.6) cm3 ,F=7.12,P=0.00, 28.0 ±4.0 vs.24.6 ±4.7 and 23.4 ±4.0,F =5.40,P =0.01] .No significantly differences were observed between group B and group A in terms of the above indices.Conclusion Insertion of absorbable biomedical membrane embedded-IUD has a good therapeutic effect and can better prevent adhesion recurrence in patients with severe intrauterine adhesion after adhesiolysis.

Objective To study the surgical diagnosis and treatment of renal tuberculosis(TB). Methods The clinical data of 42 cases with renal TB were analyzed retrospectively and the experiences of clinical diagnostic and treatment were summarized. Results Cystic irritation symptoms(78.6% ,33/42)and gross hematuria(64. 3%,27/42)were the most common symptoms in these patients. Abnormal urine were found in 83.3 % cases. Acid-fast stains on urinary sediment were positive in 28.6%(12/42)of cases. The diagnostic accuracy of B-ultrasonicgraphy,IVU,retrograde pyelography and CT examination in these patients were 19.0%(8/42),33.3% (14/42),26.2%(11/42)and 71.4%(30/42)respectively. Among all cases enrolled in the study,6 patients received antiphthisic medicine treatment,3 of them were cured and the other 3 accepted nephrectomy and partial ureterectomy after 6-12 months because of severe renal function impairment 36 cases received surgical treatment. In the 39 cases treated with operation,all of them were proved to carry renal tuberculosis by the postoperative pathological examinations. Conclusions The medical history,urine analysis,image examination should be considered synthetically in the clinical diagnosis of renal tuberculosis. The patients should be followed up closely during antiphthisic treatment period. Seriously damaged or nonfunctioning kidney should be removed promptly.

OBJECTIVE:To evaluate the effects of different doses of flurbiprofen axetil on analgesia effects of patients after laparoscopic cholecystectomy. METHODS:120 patients undergoing laparoscopic cholecystectomy were selected and randomly divid-ed into group A,B and C,with 40 cases in each group. Group A,B and C were given the mixture 100 ml of flurbiprofen axetil 100,150 and 200 mg combined with tramadol 600 mg and ondansetron 4 mg respectively and 0.9% Sodium chloride injection for patient controlled intravenous analgesia(PCIA)at the end of operation. Mean arterial pressure(MAP),heart rate(HR)and static and dynamic visual analogue scale(VAS)scores were observed in 3 groups at the end of operation,4,8,24 and 36 h after sur-gery. The incidence of incision pain,neck-shoulder pain and hypochondrium,the occurrence of ADR were recorded 36 h after oper-ation. RESULTS:After operation,There was no statistical significance in comparison of 3 groups with MAP,HR,static and dynam-ic VAS(P>0.05),4,8,24,and 36 h after operation,MAP,HR,static and dynamic VAS score of group B and C decreased sig-nificantly,there was statistical significance,compared with group A(P<0.05);there was no statistical significance in above indi-cators between group B and group C(P>0.05). After operation,the incidence of incision pain,neck-shoulder pain and hypochon-drium in group A were significantly higher than group B and C,with statistical significance(P<0.05),but there was no statistical significance between group B and group C(P>0.05). After operation,the incidence of ADR in group A and B were significantly lower than in group C,with statistical significance(P<0.05),but there was no statistical significance between group A and group B(P>0.05). CONCLUSIONS:Flurbiprofen axetil 150 mg combined with tramadol 600 mg and ondansetron 4 mg can improve he-modynamics and patient controlled intravenous analgesia in patients underwent laparoscopic cholecystectomy with lower incidence of ADR.

Objective To compare the effect of electro-acupuncture(EA) and warm-needle moxibustion(WNM) on the foot three-dimensional gait time-space parameters and surface electromyography of post-stroke patients with flaccid paralysis. Methods A total of 61 patients were randomly divided into EA group (N=30) and WNM group(N=31). Both groups were given post-stroke conventional treatment, and additionally EA group received EA while WNM group was given WNM. Before treatment and after 2 treatment courses, we detected the foot three-dimensional gait time-space parameters of pace race, stance phase, swing phase, bilateral stance phase, and step length, and surface electromyography parameters of root mean square(RMS), integrated electromyogram (iEMG) and co-contraction ratio(CR) of tibialis anterior muscle and gastrocnemius at the state of maximal isometric voluntary contraction(MIVC). Results(1) After treatment, the foot three-dimensional gait time-space parameters of the two groups were improved in various degrees (P<0.05 or P<0.01 compared with those before treatment) , and the improvement of EA group was superior to that of WNM group (P < 0.05). (2) After treatment, the RMS and iEMG of the gastrocnemius and tibialis anterior muscle as well as CR of dorsal extensor at MIVC state were improved in various degrees (P < 0.05 or P < 0.01 compared with those before treatment) , and the improvement of EA group was superior to that of WNM group(P < 0.05 or P < 0.01). Conclusion WNM exerts better effect on improving the parameters of three-dimensional gait time-space parameters and surface electromyography of post-stroke patients with flaccid paralysis than EA.

Objective To explore the effect of arsenic trioxide maintenance therapy on the long-term recur-rence rate in patients with acute promyelocytic leukemia ( APL ) . Methods From December 2011 to December 2013,60 patients with APL in the First People's Hospital of Huzhou were selected and divided into control group and observation group according to random number table, with 30 cases in each group. All patients received the same induction therapy and consolidation therapy. During the maintenance treatment period, all - trans retinoic acid ( ATRA) was given to the control group,and arsenic trioxide was used in the observation group. The serum levels and incidence of adverse reactions in the two groups were detected and compared after two cycles of the maintenance therapy. Three years of follow - up was conducted after treatment to record and compare the recurrence rate and survival rate in the two groups. Results The levels of TC and TG after 1 and 2 cycles of treatment were higher than those before treatment in both two groups(all P<0. 05),but the levels of lipid indicators in the observation group were lower than those in the control group,and the differences were statistically significant (t=2. 044,2. 175,all P<0. 05). The incidence rates of retinoic acid syndrome,elevated intracranial pressure and other adverse reactions in the observation group during the treatment were lower than those in the control group(6. 67％ vs. 26. 67％,6. 67％ vs. 30. 00％,6. 67％ vs. 26. 67％),and the differences were statistically significant(χ2 =0. 043,0. 023,0. 043,all P<0. 05). The survival rates after 2 and 3 years of treatment in the observation group were higher than those in the control group(90. 00％ vs. 66. 67％,83. 33％ vs. 60. 00％),and the differences were statistically significant(χ2 =4. 812,4. 812,all P<0. 05). The recurrence rate after 3 years of treatment in the observation group was lower than that in the control group(10. 00％ vs. 33. 33％),and the difference was statistically significant(χ2 =4. 812,P <0. 05). Conclusion For patients with APL, the application of arsenic trioxide in the maintenance therapy can produce no significant effect on their lipid metabolism, and at a certain extent, can help reduce the incidence of adverse reactions and recurrence rate,and improve the survival rate.

BACKGROUND:Brain natriuretic peptide, an important serum marker for diagnosis of cardiovascular diseases, is crucial for risk factor analysis of cardiovascular diseases.
OBJECTIVE: To analyze the relationship between brain natriuretic peptide and hemodynamic parameters before and after coronary artery bypass grafting.
METHODS:Thirty patients with coronary heart disease undergoing coronary artery bypass grafting were selected, including 13 patients with left ventricular ejection fraction≥ 50% (normal heart function) and 17 patients with left ventricular ejection fraction < 50% (cardiac insufficiency). Levels of plasma brain natriuretic peptides were detected at 1 day before transplantation, 7 hours, 1, 3, 5, 7 days after transplantation, and then the correlation between plasma brain natriuretic peptide levels and hemodynamic parameters was analyzed before and after coronary artery bypass grafting.
RESULTS AND CONCLUSION: Preoperative and postoperative levels of plasma brain natriuretic peptides were significantly lower in the patients with left ventricular ejection fraction≥ 50% than those with left ventricular ejection fraction < 50%; while in each group, the level of brain natriuretic peptides was remarkably increased after coronary artery bypass grafting (P < 0.05 orP< 0.001). Preoperative brain natriuretic peptide levels were positively correlated with New York Heart Association classification grading, left atrial diameter and left ventricular diameter (r=0.61;r=0.34;r=0.67), but negatively correlated with echocardiographic left ventricular ejection fraction and cardiac output (r=-0.75;r=-0.70). The postoperative peak level of brain natriuretic peptides was positively correlated with New York Heart Association classification grading, echocardiographic left ventricular end diastolic diameter and pulmonary artery pressure (r=0.72;r=0.70;r=0.45). These findings indicate that the plasma level of brain natriuretic peptides before coronary artery bypass grafting shows a good correlation with left ventricular ejection fraction and left ventricular end diastolic diameter, which accurately reflect the state of cardiac function before coronary artery bypass grafting.
