Objective To investigate the changes of interleukin(IL)-2 and interferon(IFN)-γin serum and synovial fluid of patients with joint injure with Kashin-Beck disease(KBD), and study the roles of IL-2 and IFN-γ in KBD joint injure. Methods In accordance with the "Diagnostic Criteria of Kashin-Beck disease"(GB16003-1995),48 cases of KBD patients and 26 healthy people(control group) from KBD endemic area in Long county Shaanxi province were enrolled in the study. KBD patient were 24 males and 24 females, respectively, aged 40 to 65 years (mean age 51 years). Forty-eight serum specimens and 28 synovial fluid specimens of patients(14 males and 14 females,respectively) were collected. Healthy control group were 13 males and 13 females, respectively. Twenty-six serum specimens of healthy controls were collected. Serum and synovial fluid IL-2 and IFN-γ levels were determined by enzyme-linked immunosorbent assay(ELISA). Results In healthy controls and KBD patients, the midian of serum IL-2 were 46.8 ng/L and 55.7 ng/L, respectively, and IFN-γ were 52.3 ng/L and 48.8 ng/L, respectively. The difference was not statistically significant between healthy controls and KBD patients(t = 0.62, 0.70, all P ＞ 0.05).In synovial fluid of KBD patient, the midian of IL-2 and IFN-γwere 48.3 ng/L and 44.1 ng/L, respectively. The difference was not statistically significant between serum and synovial fluid in KBD patients(t = 0.69, 1.72, all P ＞0.05). Conclusion Serum and synovial fluid IL-2 and IFN-γare not significantly increased in KBD patients with articular damage, indicating that IL-2 and IFN-γare not involved in KBD joint injury.

Objective To explore the effects of cluster scalp acupuncture on the behavior and expression of bcl-2 in rats after acute cerebral infarction. Methods 72 male Wistar rats were randomly divided into sham operation group (A), model group (B) and cluster scalp acupuncture group (C), 24 rats in each group. According to time after cerebral infarction, each group was reassigned to 6 h, 24 h and 3 d subgroups, 8 rats in each subgroup. The acute cerebral infarction model was established with the middle cerebral artery occlusion. The effects of cluster scalp acupuncture on the behavior and expression of apoptosis-related gene bcl-2 in the rat brain tissues with acute cerebral infarction were tested at different time. Results 3 d after cerebral infarction, the score of neuronal function in group C was significantly lower than that of group B (P<0.01). The expression of bcl-2 in brain ischemic penumbra increased in group C at different time and reached its peak at 24 h. Compared with group B, there was a statistical difference (P<0.01). Conclusion Cluster scalp acupuncture can significantly reduce the neuronal function score of rats after acute cerebral infarction and then promote the recovery of movement function. The therapy can inhibit the apoptosis by increasing the expression of bcl-2 in penumbra zone of cerebral infarction.

Objective To assess the clinical efficacy of minimally invasive internal fixation combined with percutaneous kyphoplasty (PKP) in treatment of thoracolumbar burst fractures in the elderly.Methods Twenty-one cases of neurologically intact thoracolumbar burst fractures treated by PKP between January 2007 and December 2008 were included in this study.There were 8 males and 13 females at age of 65-78 years (means,70.6 years).Mean period from injury to operation was (3.7 ± 1.1) days (range,3-7 days).The injured segments included Ti1 in two cases,T12 in six,L1 in eight and L2 in five.Kphosis Cobb' s angle,correction degree of kyphosis angle,correction loss of kyphosis,perioperative indicators,visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated after operation.Results All the cases were followed up for a period of 26-56 months (mean 34.2 months).Operation averaged 98.7 minutes (range,80-120 minutes) and showed mean blood loss of 32.8 ml (range,30-85 ml).Ambulation started at mean 18.2 hours after operation (range,8-19 hours).VAS averaged (0.9 ± 0.6) points at postoperative one week.Postoperative X-ray films revealed mean 10.4° correction of kyphotic Cobb angle,followed by mean 1.8 °of loss in the follow-up longer than 24 months.According to hyperextension and hyperflexion radiographies,there was no abnormal activity of fixed segments,implant loosening and breakage or adjacent vertebral fractures.Conclusion Minimally invasive internal fixation combined with PKP can relieve pain and restore function in a short time and is thought to be a preferable treatment option for thoracolumbar burst fractures in the elderly.

Objective: To compare the efifcacy between emergent and delayed stent implantation in patients with ST-elevation myocardial infarction (STEMI) after thrombus extraction.
Methods: A total of 82 STEMI patients who received thrombus extraction and intracoronary injection of tiroifban, sodium nitroprusside, nitroglycerin via thrombus extraction catheter and with recovered TIMI 3 lfow from 2012-11 to 2014-01 were retrospectively studied. The patients were randomized into 2 groups by SAS software: Emergent group, the patients received stent implantation immediately upon diagnosis and Delayed group, the patients were treated by anti-platelet and anticoagulant medication for 10-14 days, and then received stent implantation. n=41 in each group. The primary and secondary indicators were compared between 2 groups which including ST-segment resolution (STR), the occurrence rate of no-relfow/slow-relfow, myocardial blush grade (MBG) 3, parameters of stent, ventricular remodeling condition, the incidence of major adverse cardiac events (MACE).
Results: ①Delayed group had the post PCI STR at (68.2 ± 9.2)%, TIMI 3 grade at 97.5%, MBG 3 at 69.0%and corrected TIMI frame count (CTFC) at (19.5 ± 5.2), compared with Emergent group, P<0.05. The occurrence rate of no-relfow/slow-relfow in Delayed group and Emergent group were 2.5% and 31.0%, P<0.01. ②The parameters of stents in Delayed group and Emergent group were as the number at (1.21 ± 0.32) vs. (1.76 ± 0.76), the mean length at (28.3 ± 11.7) mm vs. (33.7 ± 12.9) mm, the mean diameter at (3.17 ± 0.76) mm vs. (2.82 ± 0.87) mm, all P<0.01. Delayed group had the higher dilating pressure than that in Emergent group, (18.5 ± 6.2) atm vs (13.6 ± 7.1) atm, P<0.01, and more patients in Delayed group receive high-pressure non-compliant balloon dilation 75% vs 23.8%, P<0.01. ③With 6 months of follow-up study, there were slightly declining trend for LVEF and LVSF in both groups than that at 1 week condition, P>0.05, while LVEDV and LVEDD increased than 1 week, P<0.05, the changes were more obvious in Emergent group, P<0.05. Delayed group had less MACE occurrence, P<0.05.
Conclusion: Delayed stent implantation in STEMI patients after thrombus extraction had reduced incidence of post PCI no-relfow/slow-relfow phenomenon, improved myocardial reperfusion and less MACE occurrence.

Objective To establish normally immortalized porcine hepatocyte lines by ectopic expression of simian virus 40 large T (SV40LT) antigen and the human telomerase reverse transcriptase(hTERT). Methods Primary porcine Hepatoeyte cells were transfeeted with recombinant retrovirus containing SV40LT or hTERT respectively. Subsequently drug resistant cell clones were screened and expanded for further studies. Immortalized porcine hepatocyte was confirmed by examination. Results The morphological phenotype of the transfected cells was similar to the primary porcine hepatocyte. One clone, HepLP, has been maintained in cultue for half year, and expanded by more than 60 passages. SV40 LT and hTERT could be detected in transfected porcine hepatocyte. Pig albumin mRNA was also detected by RT-PCR. No tumor formation occurred when HepLP cells were injected into Balb/c nude mice. Conclusions The immortalized, nontumorigenic, porcine hepatoeytes maintained the properties of porcine primary hepatocytes such as the albumin secretion. This generation of immortalized porcine hepatocyte may be helpful for bioartifical liver support system, hepatocytes transplantation, drug/toxicological studies, and liver biologic studies.
