Objective To evaluate the changes and clinical significance ot the serum levels of homocysteine (Hcy) in gastric cardia cancer patients before and after surgery.Methods Serum Hcy concentrations of 102 patients with gastric cardia cancer (including 69 case of males) and 50 healthy human were measured by enzymatic cycling assay.Results Total Hcy levels were significantly increased in male patient group compared with the levels in control group (t =5.143,P =0.001).Hcy levels were significantly lower in postoperative group compared with preoperative group [(17.08±5.31) μmol/L vs (20.34±9.26) μmol/L,(14.07±4.87) μmol/L vs (20.34±9.26) μmol/L,P ＜ 0.05].Compared with Ⅳ stage group and other TNM stage groups,significantly lower levels of Hcy were detected in patients with gastric cardia cancer (t =2.306,3.285,P =0.030,0.002).Hcy levels in patients with gastric cardia cancer were also significantly higher than those in the tumor length ＜ 3 cm,3-5 cm and ＞ 5 cm groups (t =2.461,2.147,P =0.017,0.038).Multiple logistic regression analysis indicated a statistically significant association between serum Hcy concentration and gastric cardia cancer incidence (OR =1.136,95 ％ CI 1.010-1.278,P =0.033).Increasing serum Hcy levels were significantly associated with a decreasing risk of metastatic lymph node (OR =0.865,P =0.010).Conclusion Serum Hcy levels are directly associated with risk of male patients with gastric cardia cancer,and play important roles in the development of gastric cardia cancer.

Objective To summmrize the clinical characteristics complications,antimicrobial resistance and prognosis in 15 children with streptococcus pneumoniae meningitis so as to improve the diagnosis and treatment of this disease.Methods A systematic retrospective analysis was carried out in the Qilu Children's Hospital of Shandong University from Jan.2010 to Jan.2013,and clinical data from 15 children with streptococcus pneumococcal meningitis were retrospectively analyzed and followed up for 6 months in order to observe the prognosis.Results Eleven cases of streptococcus pneumoniae meningitis occuned in the winter and spring.And it often occuned in children less than 2 years of age who lived in rural areas (13 cases).The clinical manifestations showed diverse characteristics,severe symptoms,obvious changes in symptoms and cerebrospinal fluid were observed.Severe or death cases had low temperature,low leukopenia or low blood platelet.Common complications of streptococcus pneumoniae meningitis included anemia (10 cases),hypoalbuminemia (9 cases),sepsis (8 cases).Multi-drug resistance and complications in streptococcus pneumoniae meningitis led to the therapeutic difficulties.In this study,3 cases were cured,9 cases had varying degrees of sequences,such as left languages,sports,hydrocephalus and cognitive dysfunction,and 3 cases died,and the main cause of death was multiple organ dysfunction syndrome.Conclusions Streptococcus pneumoniae meningitis mainly occurred in the winter and spring.And the children under 2 years of age who lives in rural areas were often attacked.Clinical characteristics and cerebrospinal fluid changes obviously; severe cases are common with low temperature,low leukopenia or blood platelet.And there aye often diverse complications and multi-sequelae; the problem of multi-drug resistant and complications can lead to great difficulties in the clinical treatment.

Objective To investigate the neuroprotective effect of acupuncture combined with a Chinese medicine, Danhong injection, on focal cerebral ischemia/reperfusion injury in rats.Methods Middle cerebral artery ( MCA ) occlusion was prepared by putting a nylon suture in the MCA.The MCA blood flow in the animals was restored at two hours after the MCA occlusion by withdrawing the suture to the external carotid artery (ECA).The acupoints“Baihui”(DU20) and “Zusanli”(ST36) were acupunctured and stimulated by twirling the acupuncture needle after reperfusion, and the rats were also administered with Danhong injection by intravenous injection, once every day for three days.Zea-Longa scores were recorded to assess the changes of neurological function. The rats were sacrificed at 72 h after reperfusion. Triphenyltetrazolium chloride ( TTC) staining was used to measure cerebral infarction size.Western blot was used to test the level of Bcl-2 and Bax in the ischemic penumbra.Results The acupuncture combined with Danhong injection treatment group displayed markedly lower neurologic deficit scores, reduced ischemic infarct surface, increased expression of Bcl-2 protein, and reduced expression of Bax protein, compared with those in the model group and Danhong injection alone group.Conclusions Acupuncture combined with Danhong injection show more significant neuroprotective effect than Danhong injection treatment alone on rat models of cerebral ischemia/reperfusion injury.

Results By using ROC curves to evaluate the NLR in diagnosis,the critical value was 2.75.The susceptibility, specificity,Youden index,correct index were 0.79,0.85,0.65,0.72.The susceptibility,specificity,positive predictive value,negative predictive value,correct index of NLR combined with PSA in diagnosing the prostate carcinoma were 0.85,0.83,5.00,0.18,0.68.Conclusion The application of NLR has higher susceptibility and specificity to diagnose prostate carcinoma.NLR combined with PSA can improve the susceptibility and specificity of early diagnosis of prostate carcinoma.

OBJECTIVETo compare the therapeutic effects between anatomical locked plate combined with coracoclavicular ligament reconstruction and clavicular hook plate for treatment of distal clavicle fracture of Neer type II b.

METHODSFrom August 2010 to August 2013, 42 patients with Neer II b distal clavicle fractures were randomly divided into two groups as group A and group B. In group A, there were 22 cases including 14 males and 8 females with an average age of (44.2±11.6) years old. In group B, there were 20 cases including 11 males and 9 females with an average of (45.6±12.4) years old. The patients of group A were treated with anatomical locked plate combined with coracoclavicular ligament reconstruction,the patients of group B were treated with hook plate. All fractures were fresh, the time between injuries and operation was 24 hours to 7 days (mean,72 h). General information between the two groups was comparable before operation(P>0.05). Postoperative radiographic were followed up to observe the fracture healing,internal fixation and to measure coracoclavicular distance of two groups. Shoulder function after operation was evaluated by Constant-Murley score system.

RESULTSAll patients were followed up with an average of 16.8 months (ranging 12 to 24 months). There was no nonunion,infection and other complications between two groups. The clavicular stress fracture occurred in 1 clavicular hook patient at 6 months after the operation. According to the Constant-Murley score system, that the scores of group A were 90.6±6.2, 91.8±4.8, 94.7±3.6 and 97.8±1.2 at 1st, 3rd, 6 month and last follow-up after operation were higher than those of group B 74.8±3.4, 78.4±4.4, 82.2±2.8 and 94.6±3.6 (P 0.05). The fracture healing time of group A (21.6±2.2) weeks was shorter than that of group B (25.8±2.5) weeks (P 0.05). There were no statistically significant differences between two groups in coracoclavicular distance at last follow-up (P>0.05).

CONCLUSIONThe anatomical locked plate combined with coracoclavicular ligament reconstruction need not expose shoulder and can reduce the incidence of postoperative pain and limited activity of shoulder, with fewer complication, it is advantageous to the shoulder joint function early recovery.
