The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.

OBJECTIVETo compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.

METHODSForty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures. In group A, there were 15 males and 6 females aged from 17 to 51 years old with an average of (31.60 ± 12.58) years old, preoperative Constant-Murley score was 40.25 ± 9.80, and treated with clavicular hook-plate fixation. In group B, there were 13 males and 7 females aged from 18 to 48 years old with an average of (29.40 ± 11.27) years old, preoperative Constant-Murley score was 41.45 ± 8.81, and treated with modified Weaver-Dunn surgery combined with clavicular hook-plate fixation. Operative time, blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3, 6 and 12 months after operation were evaluated.

RESULTSIn group A, operative time was 40.50 ± 24.36) min, blood loss was (75.30 ± 30.36) ml; In group B, operative time was (60.10 ± 23.55) min, blood loss was (100.70 ± 40.12) ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of (14.8 ± 3.1) months; 20 patients in group B were followed-up from 12 to 14 months with an average of (13.6 ± 1.5) months. There were no significant differences in operative time, blood loss and follow-up time between two groups. Complications were in six patients of group A and 3 patients of group B, and there were no significant meaning between two groups. At 6 months after operation, Constant-Murley score in group A was 88.85 ± 4.23, 92.15 ± 3.82 in group B; and had significant meaning between two groups (t = -2.56, P = 0.022 < 0.05). While there were no differences in Constant-Murley score in other times.

CONCLUSIONBoth of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation are effective operative methods for the treatment of Tossy type III acromioclavicular dislocation. Clavicular hook-plate fixation has advantage of less trauma, while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger, clavicular hook plate could take out earlier, also improve shoulder joint function earlier.

Objective To investigate the effect of hyperacute intensive antihypertensive treatment on the prognosis of intracerebral hemorrhage in basal ganglia region. Methods From January 2013 to December 2015,100 patients with intracerebral hematoma in basal ganglia region (onset ≤3 h)at the Neurological Intensive Care Unit,the First Affiliated Hospital of Dalian Medical University were enrolled prospectively. They all randomly received the intensive antihypertensive or standard antihypertensive treatment voluntarily. They were divided into either an intensive antihypertensive group or a standard antihypertensive group according to the random number table (n = 50 in each group). Within 1 h after beginning to treatment,the target systolic blood pressure was controlled in 130 -140 mmHg in the intensive antihypertensive group,the target systolic blood pressure was controlled in 160 -180 mmHg in the standard antihypertensive group,and the target systolic blood pressure was maintained respectively in the following 7 d. Head CT was performed gain at 24 h after treatment. The intracranial hematoma expansion was evaluated. The National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS)were used to
evaluate their prognoses. The differences of the cumulative mortality in both groups were compared at the same time. Results The incidences of hematoma expansion of the intensive antihypertensive group and the standard antihypertensive group were 12. 0% (6/ 50)and 30. 0% (15/ 50)respectively. There was significant difference between the 2 groups (χ2 = 4. 882,P = 0. 027). There were no significant differences in NIHSS scores within or between both groups at each time points (all P > 0. 05). They were followed up for 90 d,no adverse events occurred in both groups. The favorable prognosis rates of the neurological function were 36. 0% (18 / 50)and 18. 0% (9 / 50)respectively in the intensive antihypertensive group and the standard antihypertensive group. There was significant difference between the 2 groups (χ2 = 0. 411,P =0. 043). Kaplan-Meier curves showed that the cumulative mortality at 24 h,within 7 d and 90 d in the intensive antihypertensive group and the standard antihypertensive group were 4. 0% (2 / 50),6. 0%(3 / 50),and 10. 0% (5 / 50),respectively,those of the standard antihypertensive group were 10. 0%(5 / 50),24. 0%(12 / 50),and 30. 0%(15 / 50),respectively. The results of Log-rank test found that there was significant difference in cumulative mortality between the 2 groups (χ2 =6.280,P =0.012). Conclusions The intensive antihypertensive treatment in the hyperacute cerebral hemorrhage is safe and feasible in basal ganglia region. It contributes to improve prognosis of neurological function,and reduce the incidence of hematoma expansion and the 90 d cumulative mortality.

Objective To investigate the prevalence and incidence of Keshan disease (KD) and the selenium concentration of food and hair in residents of Yongjin Village, Fuyu County, Heilongjiang Province, national monitoring site, in 2007. Methods According to the Standard of Keshan Disease Surveillance and the Standard of Diagnosis of Keshan Disease(GB 17021-1997), the residents living in the monitoring site were surveyed by clinical examination and electrocardiography. For individuals whose hearts showed abnormalities, a chest X-ray photograph was taken. The selenium concentrations of the residents' food (flour) and hair were assayed by flowing injection hydride generation atomic fluoremetric method(FI-HG-AFM). Results Nineteen KD patients were found from 282 residents in 2007 KD surveillance. The prevalence of KD, latent KD and chronic KD were 6.7%(19/282), 2.8%(8/282) and 3.9%(11/282), respectively. Five of the 8 latent KD cases were newly found. In addition, there were 5 the suspected KD cases, including 2 suspected chronic KD cases. No acute KD or sub-acute KD patients were found in Yongjin Village at this monitoring site this year. The average selenium concentration of children hair and residents food were (0.3197±0.0586)mg/kg and (0.0210±0.0062)mg/kg, respectively. Conclusions New cases of KD continued to emerge, indicating that etiological factors still exist. Therefore, the emphasis of monitoring KD in furore is founding the consummate report of infectious disease system and training the personnel to increase the reliability of monitoring.

OBJECTIVETo determine the optimum treatment for viral myocarditis (VMC).

METHODSA total of 126 VMC patients were randomly divided into the control group (42 cases) that was treated with conventional Western medicine, and the intervention group (84 cases) that was treated with a combination of Chinese medicine (CM) and Western medicine intervention termed optimum proposal of integration of disease and syndrome (OPIDS). Before and after 4 weeks of treatment, the integral of CM syndrome, self-rating depression and anxiety scales (SDS and SAS, respectively), echocardiograms (ECGs), heart rate variability and left ventricular systolic function were observed.

RESULTSCompared with the control group, the intervention group showed significant reductions on the SDS and SAS (P <0.05); improvement of premature ventricular beats, atrioventricular blocks, ST-segment abnormalities, and significant T wave changes (P <0.05); greater reductions in standard deviation of NN intervals (SDNN), standard deviation for per 5 min averages NN intervals (SDANN), and root-mean-square of successive difference of NN intervals (rMSSD) (P <0.05); and increases in cardiac output, stroke volume, and ejection fraction, the last of which was statistically significant (P <0.05). Overall, the treatment efficacy rate was significantly better P<0.05) in the intervention group (75.61%) compared with the control group (69.70%).

CONCLUSIONOPIDS is quite effective in treating VMC and improves symptoms such as anxiety and depression, left ventricular systolic dysfunction, premature ventricular contraction, and cardiac autonomic nervous system dysfunction. [

OBJECTIVETo evaluate the effect of laparoscopic surgery in resection of suspected gastrointestinal stromal tumors.

METHODSA retrospective analysis was conducted among 50 patients with suspected gastrointestinal stromal tumors. All the patients underwent laparoscopic tumor resection. Thirty-eight of the patients had a preoperative diagnosis of gastric submucosa tumor by gastroscopy, and 12 had a diagnosis of small intestinal tumor by small intestinal endoscopy. The surgical procedure, operative time, estimated blood loss, time for passage of flatus, time for eating, postoperative hospital stay, operative complications, pathology and the results of follow-up were analyzed.

RESULTSIn these cases, the mean operative time was 90.84-/+26.69 min, with the mean estimated blood loss of 57.80-/+67.48 ml, mean time for passage of flatus of 50.90-/+18.87 h, mean time for eating of 2.94-/+0.79 days, and postoperative hospital stay of 8.62-/+3.56 days. No patient developed surgical complications, and all the lesions showed negative results on the margins of the resection.

CONCLUSIONAs a minimally invasive surgical approach, laparoscopic resection of suspected gastrointestinal stromal tumors reduces the intraoperative blood loss, promotes postoperative recovery of the patients and achieves R0 resection without causing serious complications.

The application potential of rep-PCR in typing beer-spoilage isolates was studied. The effects of different factors, including DNA templates and primers, on the quality and reproducibility of fingerprints were investigated. The CTAB protocol was shown to be the feasible method for DNA extraction. Primers BOXA1R and (GTG)5 were used in rep-PCR, and the PCR products were sequenced to identify strains isolated from two breweries. Rep-PCR fingerprint profiles were obtained by using GelCompar II software. Cluster analysis showed that the isolates belonging to Lactobacillus brevis, L. buchneri, L. casei/paracasei, L. plantarum are divided into 2 or 3 subgroups. In addition, the two rep-PCR fingerprint profiles complemented with each other in typing these isolates. Combining the similarity coefficient cut-off (SCC) of species, 9 unknown isolates were identified rapidly by using both fingerprint databases. The results indicate that rep-PCR is a simple, reliable and promising method for rapid identification of beer-spoilager.
