Transcatheter arterial chemoembolization (TACE) is the main treatment method for advanced hepatocellular carcinoma (HCC). As a non-invasive functional MR imaging, diffusion weighted imaging (DWI) can relfect the functional changes in tumor before morphologic changes. In the follow-up of HCC after TACE, DWI can detect new lesions and distinguish necrotic neoplastic tissue and residual neoplastic tissue timely and accurately.

The content of SO2 in Paeoniae Radix Alba (RPA) was determined by the method documented in Chinese Pharmacopoeia (CP) 2010 edition to validate the repeatability of the method for evaluating RPA, and the contents of paeoniflorin sulfonate in both the residual material and distilled solution of RPA were determined by HPLC to study the transformation of paeoniflorin sulfonate to SO2 by HCl. It was found that the repeatability of the method in CP for evaluating RPA is unacceptable, and paeoniflorin sulfonate was detectable in both the residual material and distilled solution of RPA even at "the end point" of SO2 determination, merely about 50% of paeoniflorin sulfonate was transformed to SO2 by HCl, indicating that the current SO2 determination method in CP is not able to accurately quantify SO2 in RPA. It is recommended that more special method for determining SO2 content in RPA should be developed regarding the chemical characteristics of sulfur-fumigated RPA.

To investigate the curative effect of minimally invasive sclera buckling on single retinal detachment.METHODS:Totally, 100 cases of patients with retinal detachment ( 106 eyes ) enrolled in our hospital were randomly divided into observation group and control group, 53 eyes in each group. Patients in observation group were treated with minimally invasive sclera buckling, while patients in control group received traditional limbal conjunctival incision. After surgery, patients were all followed up for 6 ~18mo, during which the retinal recurrence situation, degree of vision enhancement and compliance occurrence rate was recorded. RESULTS: The retinal reattachment rate once of observation group (96. 22%) was significantly higher than that of control group (88. 68%), there was statistically significance (P<0. 05). The vision enhancement rate of observation group (84. 90%) was significantly higher than that of control group (71. 70%), there was statistically significance (P<0. 05). The compliance occurrence rate of observation group (11. 32%) was significantly lower than that of control group (32. 08%), there was statistically significance (P<0. 05).CONCLUSlON: The improved minimally invasive sclera buckling can significantly enhance the curative effect for retinal detachment, decrease the compliance occurrence rate, improve vision function, and is a scientific, practical and rigorous tool for retinal detachment treatment.

Objective To investigate the clinical characteristics, diagnosis and treatment of placenta increta.Methods A retrospective analysis was carried out on 13 admitted cases of placenta increta from 1989～2006. Results Among the 13 cases analysed, 5 cases with a history of Caesarian section had a 0% success rate of treatment with conservative care (0/5), 100% less than that of cases with no history of Caesarian section (8/8), P＜0.05; the success rate of treatment of partial placenta increta with methotrexate with Jia Wei Sheng Hua Tang was 100%. Conclusion Caesarian section is a risk factor of placenta increta, and its prognosis is poor; however, Jia Wei Sheng Hua Tang has proven satisfactory as a supplementary treatment for placenta inereta.

This study was aimed to investigate the distribution of tumor necrosis factor-alpha (TNF-alpha)-308 gene polymorphism and its correlation with asthma in TCM syndromes between Han and Uyghur People in Xin-jiang. The polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) method was applied in the detection of TNF-alpha-308 gene polymorphism among 160 bronchial asthma cases and 40 healthy con-trols. Traditional Chinese medicine (TCM) syndrome differentiation standard on bronchial asthma was applied in the syndrome differentiation of 160 bronchial asthma cases. And gene distributions of TCM syndrome differentia-tion were compared. The results showed that there was no significant difference between the genotypes (wild-type and mutant) and allele distribution between the asthma group and the normal control group, the Uyghur asthma group and Uyghur normal control group, the Han asthma group and Han normal control group, Uyghur normal control group and Han normal control group (P > 0.05). There was no significant difference on the TNF-alpha-308 genotype distribution among different TCM syndromes. There was no significant difference on TCM syndrome distribution between Han asthma patients and Uyghur asthma patients. It was concluded that bronchial asthma in Xinjiang may be nothing to do with ethnic group, TNF-alpha-308 gene polymorphism. And the bronchial asthma syndrome differentiation type may be nothing to do with the TNF-alpha-308 genotype distribution.

Objective To determine the inhibitive effect of interferon-a on hepatic metastasis of colon cancer. Methods Metastatic model of human colon cancer was established by orthotopic implantation of histologically intact human tumor tissue into the colon wall of nude mice.The mice were randomly divided into 4 groups:(1)Control group(receiving saline solution only);(2)5-FU treatment group;(3) IFN-?-2b treatment group;and(4)5-FU combined with IFN-?-2b treatment group(combined group). 5-FU and IFN-?-2b were given via peritoneum injection 1 time/2 days for eight weeks.The mice were killed at nine weeks.The tumors were weighed,the microvessel density(MVD) was detected,and the liver was examined histologically in order to discover the micrometastasis. Results In control group, 5-FU group,IFN-2b group and combined group,the tumor weight was(1.53?0.78)g,(0.87?0.59)g,(0.81?0.43)g and ( 0.23?0.09)g, respectively;the tumor inhibition rate was 0,43.1%,47.1% and 84.9%, respectively;the hepatic metastasis rate was 85.7%,78.6%,21.4% and 0 respectively.MVD in IFN-? group and combined group was significant lower than that in control group and 5-FU group. Conclusions IFN-? can inhibit the growth and hepatic metastasis of orthotopic implanted human colon cancer by inhibiting the tumor angiogenesis.It may be more effective when INF-? combined with cyotoxic agents.

Objective To investigate the prenatal or intrapartum risk factors,resuscitation and its outcomes among full term but dying newborns after severe asphyxia (Apgar score was 0～1 at 1 min after birth).Methods Totally,39 dying full-term newborns,who were admitted to the neonatal intensive care unit of Shenzhen Maternity&Child Healthcare Hospital,Southern Medical University from January,2003 to June,2014 were analyzed retrospectively.Information on perinatal influencing factors and outcomes of resuscitation were collected and analyzed with Chi-square test.Results All of the babies were divided into died (n=7,18％,one refused to further treatment) and survived group [n=32,among which 15 suffered from hypoxic-ischemic encephalopathy(HIE) (seven mild,seven moderate and one severe case)].Fetal heart beat was undetectable in more babies in the died group than in the survived group [2/7 vs 0％(0/32),x2=4.695,P=0.028].There were 19 infants with Apgar score ≤ 5 at 5 min,and seven of them died (7/19).The other 12 survived with HIE occurred in eight cases (four mild,three moderate and one severe case) and the rest four babies did not report any neurological complications.Among the ten infants with Apgar score ≤ 5 at 10 min,seven died or refused to treatment and the other three survived with moderate HIE.Conclusions Most of the dying term babies may have promising outcomes after effective resuscitation,especially for those with Apgar score over 5 at 5 min.However,for those dying term babies with Apgar score remains ≤ 5 at 5 min,management after resuscitation should be strengthened to reduce the occurrence of any sequelae or complications.
