BACKGROUND:Umbilical cord blood transplantation can ameliorate hepatic and immunologic function,repair hepatic injury,and promote hepatic regeneration,however,the differentiation mechanism and biological characteristics remain poorly understood,and the long-term efficiency need to be explored.OBJECTIVE:To investigate the long-term therapeutic efficacy of infusing umbilical cord blood and blood plasma in treating chronic severe hepatitis B patients.METHODS:Totally 50 chronic severe hepatitis B patients received treatment at the Second Xiangya Hospital,Central South University from January 2003 to January 2004 were randomly divided into the treatment and control groups,with 25 cases in each group.All patient were accepted an ordinary synthetic treatment,and the differences between age,pathogenetic condition,medication had no significance.The umbilical cord blood was obtained from healthy full-term spontaneous delivery parturient,centrifugated,remained karyotes and cord plasma,and used within 24 hours.Patients in the treatment group were received umbilical cord blood infusion,200 mL once,1 2 times per week,totally,each patients infused 4-8 times(mean 5 times);those in the control group were infused with adult fresh blood plasma.The changes of hemogram and hepatic function were measured.RESULTS AND CONCLUSION:All the patients were followed-up for 1 year.The hemogram and hepatic function indexes were similar in the 2 groups before treatment(P ＞ 0.05).The hemogram index had no obviously difference at 1 year after treatment (P ＞ 0.05),but the alanine aminotransferase and total bilirubin levels were decreased in the treatment compared with the control group(P ＜ 0.05),but the albumin was significantly increased(P ＜ 0.05).Compared with before treatment,the platelet level had no significant changes at 1 year after treatment,but the alanine aminotransferase and total bilirubin levels were deeply decreased(P＜ 0.05),albumin was significantly increased(P ＜ 0.05);the platelet and albumin levels were dramatically decreased in the control group(P ＜ 0.05).It suggested that umbilical cord blood infusion can improve the hepatic function and hemogram;therefore,it can be served as supplementary therapeutic measure for severe hepatitis.

Defecography was performed in 110 patients without any anorectal symptoms which included 57 male and 53 female with an average age of 43. 15. Normal defecography was found in 82 cases and abnormal one in 28. The normal features of defecography in 82 patients were as follows;1.There was an increase of anorectal angle during defecation. The increase was 21. 27 degrees measured-with precise axis method and 36. 72 degrees with approximate axis method.2. Reduction or obliteration of the impression of the puborectal muscle.3. There was a shortening of the anal canal by 1. 20 cm and a widening of the caliber of the anal canal to an average of 2. 23 cm.4. The resistance of the pelvic floor was good and the decending of the perineum was smaller than 3 cm during straining. The rectovaginal septum of female subjects was not deformed during straining.5. The barium paste in the distal rectum was largely or totally evacuated with an average e-vacuation rate of 90. 55%.

Objective To analyze the safety and effect of non-invasive pressure support ventilation in 32 patients by using a helmet and to give the appropriate way of patients who need non-invasive ventilation ( NIV) support after congenital heart disease surgery. Methods Patients over one year old after congential heart disease surgery were admitted in our Department of Cardiovascular Thoracic Surgery from July 2015 to December 2015. Patients who get clinically improved within one hour were divided into the early improved group( Group-E) ,otherwise they were classified to non-early improved group( Group-NE) . The general infor-mation,diagnosis, indication of NIV, ICU and hospital stay, complications, and mortality were collected. Results Thirty-two patients were engaged in this study,including 18 patients(56. 25%) in Group-E and 14 patients(43. 75%) in Group-NE. Patients who got improved in the first hour might have a higher incidence of avoiding reintubation[83. 33%(15/18) vs. 42. 86%(6/14),P=0. 02]. The heart rate,respiratory rate, pH,PaO2/FiO2 and lactate were improved in Group-E compared with Group-NE after the first hour by using helmet. At the end of NIV,the oxygenation showed no difference but the PaCO2 was lower in Group-E. In Group-E,the values showed a trend of improvement,while the values in Group-NE showed not only no statis-tical significance in different time points but also seemed to have a tendency of hypercapnia and reduced com-fort behavior scale in the end of NIV. There were 6 cases in Group-E and 10 cases in Group-NE developed ventilation associated pneumonia with the incidence of 33. 33%(6/18) and 71. 43%(10/14),respectively, which was significant difference (χ2 =4. 571,P =0. 03). The total duration of mechanical ventilation of Group-E was shorter than that of Group-NE [ ( 136. 72 ± 151. 49 ) h vs. ( 252. 79 ± 155. 33 ) h, P <0. 05 ] . Conclusion NIV through a helmet in children could be well tolerated and avoid re-intubation. Patients who get improved earlier may have more clinical advantages,such as less time of mechanical ventilation and lower incidence of postoperative complications. Early improvement can be considered as a valuable indicator wheth-er the patient needs to use NIV continuously.

Objective To analyze the current status of neonatal resuscitation in medical institutions in China.Methods With the number of obstetric beds as the inclusion criteria,the survey was conducted in 163 medical institutions randomly selected in 11 provinces (including 51 tertiary hospitals,88 secondary hospitals and 24 primary hospitals) from October 1 to December 31 in 2011.The mail-questionnaire was sent to collect information about system establishment,personnel training,neonatal resuscitation equipment etc.Statistical data was analyzed by t-test,variance analysis and Chi-square test.Results The incidence of neonatal asphyxia among live birth babies was 2.15％ (3328/154 853) in tertiary hospitals,1.41％ (2829/200 731) in secondary hospitals and 1.50％ (701/46 695) in primary hospitals (x2=298.559,P＜0.01).The mortality rate during delivery was 0.41‰ (63/154 853),0.24‰ (48/200 731) and 0.60‰ (28/46 695) at the three different level hospitals,respectively (x2=16.993,P＜0.01).The mortality rate within 24 hours after delivery was 0.42‰ (65/154 853) in tertiary hospitals,0.24‰ (49/200 731) in secondary hospitals and 0.62‰ (29/46 695) in primary hospitals (x2 18.075,P＜0.01).About 86.5％ (141/163) of the included hospitals maintained routine neonatal resuscitation trainings,but only 73.0％ (119/163) applied resuscitation training equipments during the trainings.The outfit rate of basic neonatal resuscitation equipments (such as neonatal laryngoscope,radiant heater) was high in most hospitals,but the outfit rate of equipments recommended by the new guideline (such as umbilical venous catheter,T piece and oxygen saturation meter) was low.For example,the outfit rate of umbilical venous catheter was 23.5％ (12/51),10.2％ (9/88) and 4.2％ (1/24) in tertiary,secondary and primary hospitals respectively (x2 =6.992,P ＜ 0.05).47.9％ (78/163) of the hospitals had set up neonatal intensive care unit,with the proportion in tertiary,secondary and primary hospitals being 80.4％ (41/51),34.1％ (30/88) and 27.2％ (7/24),respectively (x2=31.677,P＜0.01).Most of the hospitals (80.4％,131/163) could ensure the pediatricians being presented in the delivery room for high risk women,and the proportion was 94.1％ (48/51),79.5％ (70/88) and 54.2％ (13/24) in tertiary,secondary and primary hospitals,respectively (x2 =16.591,P＜0.01).There were 88.3％ (144/163) of the hospitals had routine neonatal resuscitation case audit,with the proportion in the three different level hospitals being 94.1％ (48/51),92.0％ (81/88) and 62.5％ (15/24),respectively (x2 =18.388,P＜0.01).Conclusions Strengthen the training,equipment and system establishment in primary medical institutions is conducive to promote neonatal resuscitation.

ObjectiveTo evaluate the mid-term clinical effect of nano-hydroxyapatite and polyamide 66 (n-HA/PA66) intervertebral fusion cage in treatment of thoracolumbar burst fractures.Methods A total of 87 patients with thoracolumbar burst fractures were managed by thoracolumbar body resection combined with n-HA/PA66 intervertebral fusion cage from December 2007 to September 2008.The clinical effect, safety and radiographic outcomes were evaluated.Results No nerve damage was deteriorated in all the patients.The neural function was improved for 1-2 grade except for four patients at Frankel grade A.The patients were followed up for mean 21.3 months (17-24 months).The kyphosis was (14.4 ± 12.6)° preoperatively, (3.7 ± 8.7) ° immediately after surgery and (4.0 ± 8.3)° at final follow-up.The distance between the upper and lower vertebral bodies was (96.9 ± 17.2) mm preoperatively, (109.5 ± 17.1) mm immediately after surgery and (108.3 ± 16.4) mm at final follow-up.No cage replacement, internal fixation breakage or neurologic impairment were observed during follow-up period.There were 58 patients with grade E fusion, 22 with grade D fusion and 7 with grade C fusion.ConclusionsAnterior decompression combined with n-HA/PA66 intervertebral fusion cage is an effective method for treatment of thoracolumbar burst fracture.The kyphosis is rectified and the intervertebral distance is corrected, with a high rate of fusion.

Objective To investigate the clinical application of anti-β2 glyeoprotein Ⅰ antibodies (IgG, IgM, IgA)in systemic lupus erythematosus(SLE). Methods The anti-β2-GP Ⅰ antibodies and anti-cardiolipin antibodies(ACL) level were measured by ELISA in 100 SLE patients, 39 other rheumatoid arthri-tis patients and 30 healthy control people. Their clinical application was analyzed in SLE diagnose and thera-py. Results The level of anti-β2-GP Ⅰ (IgG, IgM, IgA)were significantly higher in SLE than that in healthy (P < 0. 01 ). Sensitivity, specificity, positive predictive value and negative predictive value were 17.2%, 95.7%, 85.0% and 44. 6%, respectively. There was a significant and positive correlation be-tween anti-β2-GP Ⅰ antibodies and ACL antibodies ( IgG, IgM, IgA) (r = 0.418, 0. 624, 0.518, 0. 583, P <0.01). In multivariate analysis the factors(anti-β2-GP Ⅰ antibodies, ACL antibodies, dsDAN, u1-RNP, Sm, SSA, SSB, Jo-1, Scl-70, P-protein, PT, APTT) associated with SLE disease activity index(SLEDAI) were anti-β2-GP Ⅰ (IgG) and dsDNA. Conclusion anti-β2-GP Ⅰ antibody has high specificity and positive predict value, also is associated with SLE's thrombosis. It has some values in the clinical application.
