Objective To determine the levels of serum anterior gradient 2 (AGR2) before and after treatment in nasopharyngeal carcinoma (NPC) patients, and investigate the relationship of AGR2 and clinical pathological characteristics of NPC patients.Methods The serum levels of AGR2 were detected by enzyme linked immunosorbent assay (ELISA) in 55 NPC patients (NPC group) before and after treatment, 30 patients with nasopharyngeal inflammation (inflammation group) and 20 healthy controls (health control group).The correlations between serum AGR2 before and after treatment and clinical pathological characteristics of NPC were analyzed.The NPC patients received radiotherapy and were followed up for 6 months, and the therapeutic effect was evaluated.Results The serum AGR2 levels in NPC group before treatment, inflammation group and health control group were (22.92±5.24)μg/L, (9.50±4.15)μg/L and (8.75±2.18)μg/L respectively, and the difference was statistically significant (F=268.400, P=0.000).The level of serum AGR2 in NPC group was obviously higher than that in inflammation group (t=14.241, P=0.000) and health control group (t=15.254, P=0.000).The level of serum AGR2 in NPC group after treatment was significantly lower than that before treatment [(15.15±10.33)μg/L vs.(22.92±5.24)μg/L, t=12.774, P=0.000].In NPC patients, serum AGR2 levels of clinical Ⅲ-Ⅳ stage group before and after treatment were higher than those of clinical Ⅰ-Ⅱ stage group (t=5.938, P=0.000;t=0.759, P=0.032).Serum AGR2 levels of lymph node metastasis group before and after treatment were higher than those of no lymph node metastasis group (t=6.879, P=0.000;t=2.700, P=0.009).Serum AGR2 levels of carotid sheath and skull base involvement groups before treatment were higher than those of non-involvement groups (t=8.342, P=0.000;t=8.255, P=0.009).Serum AGR2 levels of cranial nerve involvement group before and after treatment were higher than those of non-involvement group (t=7.743, P=0.000;t=3.021, P=0.004).The serum AGR2 level after treatment in complete response patients [(13.86±2.93)μg/L] was significantly lower than that in partial response patients [(15.85±3.24)μg/L, t=2.267, P=0.028] and invalid patients [(20.65±6.59)μg/L, t=4.935, P=0.000].The serum AGR2 level in partial response patients was significantly lower than that in invalid patients (t=3.196, P=0.004).Conclusion The level of serum AGR2 in NPC patients increases obviously.AGR2 plays an important role in the genesis and development of NPC, and can be used as a new marker of NPC for judging the clinical therapeutic efficacy and prognosis.

Objective To evaluate the curative effect of valsartan associated with low-dose amiodarone on the recurrence of atrial fibrillation (AF), the left atrial diameter (LAD), P wave dispersion (Pd) and the maximum P wave duration (Pmax) in patients with paroxysmal AF. Methods 76 patients with paroxysmal atrial fibrillation (PAF) were randomized to valsartan (test group) and placebo (placebo group), both associated with low-dose amiodarone, and were followed up for 18 months. The patients were asked to report any episode of symptomatic atrial fibrillation and to perform an ECG as early as possible. AF load, Pmax, Pd and LAD were measured before and at the 6th, 12th, and 18th month after the treatment. Results At least one ECG-documented episode of AF was reported in 16% of the patients in test group and in 41% in placebo group, the difference was significant (P

Objective To explore the clinical characters and the relationship between prognosis and treatment in childhood acute non-lymphocytic leukemia(ANLL).Method We summarized and analyzed the cases with acute non-lymphocytic leukemia in children patients from our hospital admission between Jan 2003 and Sep 2007.Results ①The M1,M2 subtype of childhood ANLL were about 37.1%;the clinical situation was various;extramedullary infiltration was not uncommon;②A totle complete remission(CR)rate was 68.6% and the CR rate of one course chemotherapy was 40.1%;③The CR rate of acute promyelocytic leukemia(APL)was 87.5% and a average of continues CR(CCR)was 33 months after the treatment of ATRA combined with As2O3;④Among five patients finished all the courses of high dose Ara-c(HDAra-c)intensification therapy,three were CCR over 36 months.Conclusion ①The CR rate of one course chemotherapy was correlated to the intensity of treatment;②The treatment of As2O3 can help to lower the relapse of APL and enhance the event-free survival(EFS);③The treatment of HDAra-c can help to increase the EFS rate of childhood ANLL.

OBJECTIVETo explore the clinical effects of internal fixation with lag screws plus an anti-sliding plate for the treatment of Hoffa fractures of the lateral femoral condyle.

METHODSFrom May 2006 to May 2014, 17 patients with Hoffa fractures of the lateral femoral condyle were treated with lag screws plus an anti-sliding plate. There were 13 males and 4 females, ranging in age from 27 to 59 years, with a mean of 32.5 years. All the fractures were fresh and closed fractures. According to the Letenneur's classification, 8 cases were type I, 4 cases were type II, 5 cases were type III. All the patients had no injuries of the cruciate ligament and the another part of the knee. Operative incision and fracture healing time were observed, knee joint function was evaluated by Letenneur system and HSS standard.

RESULTSThe patients were followed up from 10 to 24 months with a mean of 14.6 months. All incisions achieved primary healing, and no internal fixation breakage, malunion, femoral candyle necrosis, deep vein thrombosis of lower extremity were found. Fracture healing time was from 4 to 9 months with an average of 4.7 months. According to Letenneur's functional assessment, 10 patients got an excellent results, 4 good, 3 fair. Total HSS score was 91.1 +/- 4.7 on average,15 cases obtained excellent results, 2 good.

CONCLUSIONInternal fixation with lag screws and an anti-sliding plate can result in excellent effects for Hoffa fractures of the lateral femoral condyle. The key to a successful surgery is an anatomic reduction and rigid fixation of the fracture.

Objective To explore the the analytical method for the quality difference of Radix Salviae Mihiorrhizae (RSM) injection. Methods Parallel intercomparison experiment was carried out in different batches of RSM injection samples which had different degrees of adverse drug reaction. The samples were analyzed by gel size exclusion chromatog-zraphy and C18 HPLC fingerprint. Subtractive analysis was used to reveal the information of the non-low molecular weight phenolic acids. Results There were obvious differences between the results of size exclusion chromatography. The amount of the non-low molecular weight phenolic acids from different batches of the samples was also different, which was correlated with the degrees of acute toxicity in guinea pigs. Conclusion The amount of the non-low molecular weight phenolic acids varies with different batches of Radix Salviae Mihiorrhizae injection. It is suggested that non-low molecular weight phenolic acids can be used for the quality control of Radix Salviae Mihiorrhizae injection. For the first time, the perspective that the corresponding relationship between the fingerprint and their toxicities of Traditional Chinese medicine injection may be one of the most important fields is put forward.

Objective To analyze clinical features and sum up experience for the treatment of ischemic bowel disease. Methods Clinical data of 73 patients with the diagnosis of ischemic bowel disease were retrospectively analyzed. ResultsTwenty-eight patients were male and 45 patients were female. The median of age was 65 years (range of 38 to 89 years). Forty-eight patients were associated with hypertension, 23%(17/73) patients had a history of coronary disease and 15% (11/73) had diabetes. Seventy patients presented symptom of abdominal pain and 93% (68/73) had hematochezia. Symptoms relieved by conservative treatment in 96% (63/66) patients. Nine patients underwent a surgery. One patient died of sepsis postoperatively. One suffered from colostomy necrosis and leakage of the rectum segment. Conclusion 1. Elder patients presenting symptoms of abdominal pain and hematochezia, especially with a history of cardio-cerebrovascular disease and diabetes should be considered for the possibility of ischemic bowel disease. 2. Most patients with ischemic bowel disease could be successfully treated by conservative therapy. 3. Surgery for patients with chronic relapsing and nonresponsible symptoms was difficult and patients often suffer from high postoperative complications.

Objective To evaluate the relationship between echocardiographic epicardial adipose tissue thickness(EAT) and the presence and severity of coronary artery disease(CAD). Methods One hundredand forty-seven patients (101 patients with CAD and 46 patients with normal coronary arteries by diagnostic coronary angiography) were enrolled. EAT thickness was measured using 2-D echocardiographic parasternal long-and short-axis views. EAT thickness measurements were compared with angiographic findings. Results EAT was significantly higher in CAD group comparison to control group [(7.41 ± 1.63)mm vs (4.41±1.60) mm, P ＜0.01 ]. Furthermore, EAT increased with the severity of CAD [(8.53 ± 1.00)mm vs (6.36 ±1.73)mm, P ＜0.01]. Gensini's score significantly correlated with EAT (r = 0.71, P ＜0.01 ). EAT thickness ≥5.35 mm had 87.13% sensitivity and 80.42% specificity (ROC area 0. 89, P = 0.01,95% CI [0.84 - 0.9;]) for predicting CAD. Conclusions EAT thickness, which is easily and non-invasively evaluated by transthoracic echocardiography, can be an adjunctive marker to classical risk factors for the prediction of CAD, it was significantly correlated with the severity of coronary artery disease.
