Objective To evaluate the efficacy of arthroscopic one-stage reconstruction of anterior and posterior cruciate ligaments with LARS artificial ligaments. Methods From October 2009 to December 2011, 8 patients with combined injury to anterior and posterior cruciate ligaments received arthroscopic one-stage reconstruction with LARS artificial ligaments. They were 7 men and one woman, aged from 26 to 52 years ( average, 35. 3 years ) . The time from injury to operation ranged from 17 to 21 days, averaging 19 days. Pre-operative and intraoperative inspections showed complete tear of both anterior and posterior cruciate ligaments. Inter national Knee Documentation Committee ( IKDC ) scoring was used at 6 months postoperation to grade the knee movement of the patients; Lysholm scoring was used at final follow-ups to evaluate the knee function. Results The operating time for this series ranged from 85 to 102 minutes ( average, 93 minutes ) . All the patients were followed up for 6 to 24 months ( average, 12 months ) . Wound infection at upper tibia occurred in one patient, which responded to debridement and screwing 4 weeks after operation. All the patients got rid of instability of the knee joint, and gained normal knee extension and fine functional recovery. At final follow-ups, the range of motion of the knee ranged from 100° to 125° ( average, 108. 4°) . Follow-ups revealed no breakage or loosening of the ligaments. By the IKDC scoring, of the 8 patients who had been graded all as D before opera-tion, one was improved into A and 7 into B. The Lysholm scores at final follow-ups averaged 86. 1+4. 8, sig-nificantly higher than the postoperative value ( 18. 7+3. 1 ) ( P < 0. 05 ) . Conclusion Arthroscopic one-stage reconstruction of anterior and posterior cruciate ligaments with LARS artificial ligaments can restore the stability of knee joint and obtain satisfactory short-term results.

Objective To optimize the temporal bone scanning parameters, upgrade the picture quality, shorten the scanner time, and decrease the radiographic exposure during the scanning. Methods The scanning was performed on 20 volunteers using 16 spiral CT in the same position and range with optimizer parameters and general parameters respectively, and then the volume data were collected. Results Through comparision and analysis of the images of the 20 volunteers, 17 of them using the optimizer parameters were better than those using general ones, 2 of them showed no obvious difference, and 1 was not as good as the general one. Conclusions Through the experiment and the statistics of 1000 cases using optimizer parameters, the picture quality using optimizer parameters is better, the scanner time is 1/7 of the general scanning, and the radiographic exposure is decreased. Optimizer parameters are better than the general ones and worth popularizing.

The initiation and development of gastric cancer is due to the effects from both external and internal factors.Recent researches show that external environment factors regulate and control the key genes expression during the process of cell's growth and development through epigenetic modification such as DNA methylation or demethylation,histone modification and small RNA,thus playing an important role in gastric cancer's occurrence and development.

Objective To explore the clinical value of testing LDH and IL-2 in the serum of the patients with the acute leukemia. Methods The LDH and IL-2 in the serum of 15 patients with the acute leukemia were tested,who consist of the patients with first treatment,recurrence and remission,compared with these of the normal people in control group.Results The LDH of the patients with first treatment and recurrence was obvious higher than tllat of the patients with remission;the IL-2 of the patients with first treatment and recurrence was obvious lower than that of the patients with remission.The LDH descent and IL-2 ascent were found in the patients with remission.Conclusion The cell load of the patients with the acute leukemia can depress the expression of IL-2 in the patients with the acute leukemia.

Objective To explore the clinical value of enhanced recovery after surgery (ERAS) in the perioperative period of biliary surgery.Methods The prospective study was adopted.The clinical data of 800 patients diagnosed as benign biliary tract diseases who were admitted to the Cangzhou's Central Hospital from March 2011 to January 2015 were collected.Patients were randomly divided into the case and control groups by random sequence method.The patients of case group received the ERAS management and patients of the control group received traditional perioperative management.(1) Stress state evaluation:the insulin resistance (IR) index and level of serum C-reactive protein (CRP) were calculated.(2) Levels of inflammatory cytokines:levels of IL-6 and TNF-α in the 2 groups were detected by enzyme-linked immunosorbent assay (ELISA).(3)Nutritional status:level of serum prealbumin (PA) was detected.(4) Postoperative status:time to anal exsufflation,time of defecation,duration of hospital stay and treatment expenses were recorded.(5) Postoperative complications were observed.Measurement data with normal distribution were represented as x ± s and comparison between groups was analyzed using t test.Repeated measurement data were analyzed by the repeated measures ANOVA.Count data were represented as ratio and analyzed using the chi-square test.Results The 800 patients were screened for eligibility,including 400 in each group.(1) Stress state evaluation:the levels of IR and CRP from pre-operation to 7 days after operation were from 3.8 ± 0.8 to 3.7 ± 0.7 and from (18 ± 5) μg/L to (27 ±8) μg/L in the case group,from 3.9 ±0.9 to 3.8 ±1.0 and from (18 ±5) μg/L to (38 ±9) μg/L in the control group,respectively,with statistically significant differences in the changing trends (F =12.38,17.85,P ＜0.05).(2) Comparisons of levels of inflammatory cytokines:levels of IL-6 and TNF-α from pre-operation to 7 days after operation were from (9.3 ± 3.1) ng/L to (12.5 ± 2.8) ng/L and from (10.2 ± 3.5) ng/L to (12.8 ±3.3)ng/L in the case group,from (8.9 ±3.3)ng/L to (17.3 ±6.5)ng/L and from (9.9 ±2.8) ng/L to (14.3 ±4.2)ng/L in the control group,with statistically significant differences in the changing trends (F =19.93,15.74,P ＜ 0.05).(3) Comparison of nutritional status:level of PA from pre-operation to 7 days after operation was from (335 ± 53)mg/L to (332 ±50)mg/L in the case group and from (330 ± 49)mg/L to (331 ± 45)mg/L in the control group,with a statistically significant difference in the changing trends (F =4.46,P ＜ 0.05).(4)Comparisons of postoperative status:time to anal exsufflation,time of defecation,duration of hospital stay and treatment expenses were (30 ± 10)hours,(51 ± 13) hours,(7.7 ± 2.5) days,(10.2 ±2.3) × 103 yuan in the case group and (54 ± 8) hours,(70 ± 16) hours,(15.4 ± 3.1) days,(15.6 ± 4.7) × 103 yuan in the control group,with statistically significant differences (t =37.73,18.62,38.67,20.64,P ＜0.05).(5) Comparisons of postoperative complications:incidence of complications was 15.00％ (60/400)in the case group and 22.50％(90/400) in the control group,and the numbers of patients with incision infection,nausea and vomiting,abdominal infection,intra-abdominal infection,urinary tract infection,intro-abdominal hemorrhage and bile leakage were 23,15,8,5,4,3,2 in the case group and 30,20,13,10,7,5,5 in the control group,respectively,showing statistically significant differences in the incidence of complications (x2=7.39,P ＜ 0.05).Conclusion ERAS management in the perioperative period of biliary surgery is beneficial to postoperative recovery of patients,and it can also relieve postoperative stress state and inflammatory response,reduce the duration of hospital stay,treatment expenses and incidence of postoperative complications.

P2 X7 receptor is a member of ATP-gated non-selective cation channels;and is one subtype family of the P2X purinergic receptor.Signaling pathways of P2X7 receptor couple with several key inflammatory molecules including IL-1β;IL-6 and COX-2;which suggests that P2 X7 receptor plays a key role in the development of dis-eases via increased inflammation;indicating its potential as a novel therapeutic target.Recent studies show that P2 X7 receptor has a relationship with renal diseases.This article reviews the effect of P2 X7 receptor on renal diseases and its mechanism.P2 X7 receptor may be a new drug target;and its selectivity antagonist may be a new therapeutic agent for the treatment of renal diseases.
