Objective To investigate the protective effects of mild hypothermia on cells in the CA_1 region of the hippocampus in gerbils following global ischemia-reperfusion injury(IRI),and to explore their mechanism. Methods IRI models were established in 75 gerbils.Any changes in TUNEL positive cells and the expression of Bax and Cytochrome C were then observed in normothermic(N) ,hypothermic(H)and sham(S) groups through immu- nohistochemistry methods.Results In the H group(as compared with the N group)apoptotic cells in the CA_1 sub- field of the hippocampus significantly decreased.The expression of Bax and Cyt C at 3 h,6 h and 1 d were de- creased,and the expression fastigium was delayed.Conclusion Mild hypothermia can moderate and delay cell ap- optosis,and its mechanism might be related with reducing and delaying the expression of Bax and Cyt C released by mitochondria.

Objective To assess the relationship between the Chlamydia pneumonia(CPn)infection and coronary heart disease(CHD).Methods Blood samples from 200 CHD patients and 100 heathy controls were col-lected,and Cpn IgM and Cpn IgG were tested by ELISA.Results The Cpn IgM were found in 113 cases (56.5%) and in 24 controls(24.0%).The Cpn IgG positive cases were in 145(72.5%) patients and in 43 controls (43.0%).The positive rate of Cpn IgM and Cpn IgG in CHD group Was higher than that in control group(P<0.05).Conclusion:CPn positive rate is higher in CHD group than that in control group.Cpn is closely related to the pathogenesis of CHD.

Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) has become the standard first-line treatment for advanced non-small cell lung cancer (NSCLC) patients with EGFR-sensitive mutations. However, acquired resistance cannot be avoided during the targeted treatment of EGFR-TKI, which may lead to the progression of NSCLC. Among them, approximately 50% of patients present with primary lung lesions and/or initial metastastic lesion progression. As a major local treatment, radiation therapy plays an irreplaceable role in the management of patients with advanced cancer. Stereotactic body radiation therapy (SBRT), which is implemented with the Cyberknife, is the most advanced radiation therapy technology to better meet clinical needs. In recent years, based on the abovementioned patterns of tumor recurrence, the treatment mode of pulmonary-lesion SBRT combined with EGFR-TKI can improve the tumor-free survival in advanced NSCLC patients, which has attracted widespread attention. In this article, the clinical research progresses on this combined therapeutic strategy were reviewed.

Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing＞50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P＜0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P＜0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.

The prescriptions containing pericarpium citri reticulatae that built by Professor. Yan were collected to build a database based on traditional Chinese medicine (TCM) inheritance assist system. After analyzed by data mining, such as apriori algorithm, the frequency of single medicine, the frequency of drug combination, the association rules between drugs and core drug combinations can be get from the database. Through the analysis of 1 027 prescriptions with pericarpium citri reticulatae, these prescriptions were commonly used to treat stomach aches, cough and other syndromes. The most frequency drug combinations were "Citri Reticulatae Pericarpium-Poria", "Paeoniae Radix Rubra-Citri Reticulatae Pericarpium" and so on. The drug association rules that the confidence was 1 were "Glycyrrhizae Radix ex Rhizoma --> Citri Reticulatae Pericarpium", "Paeoniae Alba Radix-Cyperi Rhizoma --> Citri Reticulatae Pericarpium", "Poria --> Citri Reticulatae Pericarpium", and so on. The drugs in the prescriptions containing pericarpium citri reticulatae that built by Professor Yan mostly had the effects of regulating the flow of Qi and invigorate blood circulation, which reflected the clearly thought when making prescriptions.

Objective To evaluate the effects of electroacupuncture (EA) at Zusanli and Chize on sepsisinduced acute lung injury (ALI) in patients.Methods Sixty patients with sepsis-induced ALI/respiratory distress syndrome,aged 43-78 yr,weighing 49-89 kg,with their APACHE-Ⅱ scores of 16-23 and oxygenation index of 125-256 mm Hg,were randomly divided into 3 groups (n =20 each):conventional therapy group (group S),conventional therapy + acupuncture at non-acupoint group (group SNE) and conventional therapy + acupuncture at acupoint group (group SE).Bilateral Huantiao and Chize points were stimulated with electric stimulator (frequency 2/50 Hz,wave length 300μs,starting at a voltage of 0 and increasing by 0.1 mA every time until the maximal tolerance level was reached) for 30 min once a day for 5 days based on the conventional therapy in group SE.In group SNE,EA was performed at the non-acupoint based on the conventional therapy and the parameters of EA were same as those previously mentioned in group SE.Before EA stimulation (T1) and at 3 and 5 days after the end of EA stimulation (T2-3),arterial blood samples were taken for blood gas analysis,oxygenation index (OI) was calculated,and APACHE-Ⅱ] scores were assessed.Venous blood samples were collected at T1 and T3 for detection of TNF-α and IL-10 concentrations in the broncho-alveolar lavage fluid (BALF) and serum (by ELISA).Results Compared with the baseline value at T1,OI was significantly increased and APACHE-Ⅱ scores were decreased at T2 and T3,and TNF-α concentrations in the BALF and serum were decreased and IL-10 concentrations in the BALF and serum were increased at T3 in the three groups (P ＜ 0.05 or 0.01).The OI was significantly higher and APACHE-Ⅱ scores were lower at T3 than at T2 in the three groups (P ＜ 0.05).Compared with group S,the OI was significantly increased at T2 and T3,APACHE-Ⅱ scores and TNF-α concentrations in the BALF and serum were decreased at T3,and IL-10 concentrations in the BALF and serum were increased at T3 in group SE (P ＜0.05 or 0.01),and no significant changes were found in the parameters mentioned above in group SNE (P ＞0.05).There were no significant differences in the incidence and survival rate of multiple organ dysfunction syndrome among the three groups (P ＞ 0.05).Conclusion EA at Zusanli and Chize is helpful in mitigating sepsisinduced ALI in patients,and regulation of the balance between proinflammatory factors and anti-inflammatory factors and inhibition of inflammatory responses may be involved in the mechanism.

AIM:To observe the changes of macular thickness in patients after cataract operation.
METHODS: A total of 126 patients ( 133 eyes ) were divided into two groups that were included in this study. The group (68 eyes of 64 case) with phacoemulsification combined intraocular lens implantation and ( 65 eyes of 62 cases ) with manual small incision cataract surgery ( MSICS) . There was no complication before and during the surgery. Optical coherence tomography ( OCT) was examined 1, 3mo before and after surgery. The visual acuity and macular thickness were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test was used before and after surgery. Independent-samples t test was used in two groups before and after surgery,α=0. 05.
RESULTS: The cataract phacoemulsification group:preoperative and 1mo after surgery, the mean macular thickness was 241. 3±10. 9μm and 279. 7±16. 5μm, with significant difference ( P < 0. 01 ). The mean macular thickness was 245. 6±12. 6μm 3mo after surgery without statistical difference compared with preoperative ( P>0-05). The mean macular thickness was 279. 7±16. 5μm 1mo after surgery and 245. 6±12. 6μm 3mo after surgery with statistical difference(P<0. 05). Three eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes of them was resolved 3mo after surgery. The group of MSICS: preoperative and 1mo after surgery, the mean macular thickness was 240-5±11. 9μm and 280. 7±16. 8μm, with significant difference (P<0. 01). The mean macular thickness was 246. 6±13. 2μm 3mo after surgery without statistical difference compared with preoperative ( P >0-05). One month after surgery and 3mo after surgery, the mean macular thickness were 280. 7±16. 8μm and 246-6±13. 2μm, with statistical difference (P<0. 05). Two eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes were resolved 3mo after surgery. Between the two groups pre-operation or after operation for 1, 3mo respectively P values were without statistical difference (P>0. 05).
CONCLUSION: The macular thickness and macular edema can be found 1mo after cataract phacoemulsification and MSICS. Three months post-operatively, macular edema disappears and does not show statistical difference compared with preoperative. The increase of macular thickness has no obvious relationship with the choice of surgery.
