ObjectiveTo observe the clinical efficacy of acupoint injection in treating diabetic gastroparesis.MethodThe eligible subjects with diabetic gastroparesis were randomized into atreatment group and a control group following the random number table. In addition to the conventional managements for diabetes, the treatment group was given acupoint injection, while the control group was prescribed with oral administration of Domperidone tablets. For both groups, 30 d treatment was taken as a treatment course. The clinical symptoms, gastric emptying, and electrogastrogram were observed before and after treatment.Result The total effective rate was 92.3% in the treatment group, significantly superior to 85.3% in the control group (P<0.05); the symptoms including early fullness, abdominal bloating, upper abdominal pain, nausea, and vomiting in the treatment group showed more significant improvements than that in the control group (P<0.05); the amplitudes and frequencies showed on the electrogastrogram before and after dinner were significantly increased after treatment in both groups (P<0.05), and the treatment group was significantly superior to the control group in comparing the amplitude and frequency before and after dinner duringthe same period (P<0.05).ConclusionAcupoint injection can significantly mitigate the symptoms of diabetic gastroparesis, moreover, it can improve the gastric electrical rhythm, and it can produce a better therapeutic efficacy compared to oral medication.

Objective:To study the coronal microleakage of flared root canal teeth restored with computer aided design and computer aided manufacturing (CAD/CAM)fiber post and core.Methods:60 extracted human mandibular premolars with single canal were divided into 3 groups randomly(n =20).The roots of the teeth were restored with CAD/CAM glass fiber post and core(group A), prefabricated glass fiber post(group B)and gold alloy dowel-and-core(group C)respectively.The specimens were immersed in India ink for 4 weeks.Subsequently all teeth were demineralized,dehydrated and rendered transparent.Then coronal microleakage was ob-served with stereomicroscope.Nonparametric data were analyzed.After that,All the specimens was demineralized completely in nitric acid,Then the interface between the post,resin cement and canal wall was observed and recorded.Results:The microleakage was found in all the 3 groups,group A and C showed less microleakage than group B(P <0.05).But no difference was detected between group A and C(P >0.05).Microleakage mostly appeared at the interface between post and resin cement in group A and C,while in group B,it appeared between resin cement and the wall of root canal totally.Conclusion:CAD/CAMfiber post and core demonstrates less coronal microleakage than prefabricated glass fiber post.

Objective To determine the relationship between serum levels of MCAF/MCP-1 (monocyte chemotactic and activating factor/monocyte chemoattractant protein-1), RANTES(regulated on activation, normal T-cell expressed and secreted) and the disease activity of systemic lupus erythematosus(SLE). Methods Serum levels of MCAF and RANTES were measured by ELISA. Results ①Serum level of MCAF but not RANTES, was significantly increased in patients with SLE as compared with controls. ②Serum level of MCAF but not RANTES, was markedly higher in patients with active disease than those with inactive disease. ③No significant differences were found in the serum levels of MCAF and RANTES between patients with renal damage and those without. Conclusions These results suggest that MCAF may be involved in the pathogenesis of SLE, and serum MCAF levels could be an indicator for the disease activity of SLE.

Objective:To evaluate the efficacy and safety of pegylated liposomal doxorubicin (PLD) in CHOP regimen for un-treated elderly patients with advanced diffuse large B-cell lymphoma (DLBCL). Methods:In a prospective phase II study, we analyzed the feasibility of PLD-modified CHOP regimen in elderly patients with advanced stages of DLBCL. PLD was administered at 30 mg/m2 in combination with cyclophosphamide, vincristine, and prednisone at standard doses every 21 d for six cycles. CD20 positive patients were given option for rituximab treatment. Results:From November 2011 to March 2014, 30 patients with a median age of 70 years (range:63 to 80) were enrolled in this study. Up to 24 cases (80.0%) obtained an International Prognostic Index of≥3. The overall re-sponse rate was 86.7%, and the complete remission rate was 66.7%. With a median follow-up of 20.1 months, the 18-month overall and progression-free survival rates were 82.4%and 70.1%, respectively. The main toxicity was neutropenia, reaching grades 3 to 4 in the 24 cases (80.0%). No significant changes existed in patients' left ventricular ejection fraction and serum troponin-T during the study. Four patients (13.3%) showed asymptomatic abnormal changes in electrocardiogram after PLD infusion. Conclusion:CHOP regimen with PLD is an effective alternative for the treatment of DLBCL in elderly patients, exhibiting an acceptable toxicity.

Objective To analyze the practicality of current diagnostic criteria of invasive fungal infection (IFI) in patients with hematologic diseases/malignant tumors,so as to enhance the recognition of characteristics of pulmonary IFI after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods The clinical features of 51 cases with IFI after allo-HSCT were analyzed retrospectively.Results Pulmonary IFI accounted for 42.1％ (51/121) of the whole infectious pneumonia diagnosed among the patients admitted during the study.One (2.0％) case was proven diagnosis ; 24 (47.1％) were probable diagnosis and 26(51.0％) were possible diagnosis.The using of immuno-suppressors and corticosteroids,and the presence of graft-versus-host disease (GVHD) were the main host factors.The patients with two or more host factors simultaneously accounted for 66.7％ (34/51) of all pulmonary IFI patients.Totally 94.1％ (48/51) of the patients with pulmonary IFI presented nodules and/or patches as the main features in high resolution computed tomography (HRCT) scanning.The positive rates of fungal antigen detection were 58.6％ for G test and 33.3％ for GM test,which were relatively high.Twenty patients (39.2％) showed decrease of arterial partial pressure of oxygen and hypoxia in blood-gas analysis.Conclusions For the diagnosis of pulmonary IFI post allo-HSCT,the administration of immuno-suppressors and corticosteroids,and the presence of GVHD were the main host factors.Nodules and/or patches were the main features in HRCT image.Fungus antigen detection is the main tool to support clinical diagnosis.

Objective To observe the influence of local-anaesthetic combined with dezocine on brachial plexus block and postoperative analgesia.Methods 60 patients scheduled for unilateral upper limb operation were randomly divided into two groups of C group and D group with 30 cases in each group.The brachial plexus block was performed under ultrasound guiding.Two groups received a bolus injection of local anesthetic 30ml,but the local bolus injection of D group consisted of Dezocine 10mg.The tine of sensory blocked producing effect,anesthesia effect,sensory blocked duration were observed.Two hours after sensory nerve recovered,the scores of VAS pain and Ramsay Sedation were recorded.Adverse reactions of perioperation were also observed(nausea,vomiting,dizzy,respiratory,urine retention,pruritus).Results The sensory blocked duration in D group was(7.1±1.1)h,which was significantly longer than that of C group[(4.5±0.8)h](t=10.47,P＜0.01);Two hours after sensory nerve recovered,the score of VAS pain in D group was(1.7±0.7)points,and significantly lower than that of C group[(3.9±1.0)points](t=9.87,P＜0.01).Both two groups had no adverse reactions.Conclusion Addition dezocine 10mg to local anesthetic solutions for interscalene brachial plexus block,it could prolong the sensory block duration,provide satisfactory postoperative analgesia,have no adverse reactions.

Objective To investigate the possibility of anti-liver fibrosis of 13-estradiol nanoparticle prepared by interfacial polymeri-zation method with butylcyanoacylate as carrier material (E2-PBCA-NP) and its effect on the expression of transforming growth factor β1 and connective tissue growth factor in pig serum induced animal fibrotic model. Methods Male Sprague-Dawley (SD) rats were random divided into five groups. Except normal control group, other four groups were all given intraperitoneal injection with pig serum. Therapeutic drugs were administered to rats from the ninth week after injection of pig serum. All rats were killed at the end of the twelfth week. Several experi-ments were done as below, the tissues of liver were observed by Masson staining, and the mRNA of TGF-β1 and CTGF of liver samples were detected by RT-PCR. Meanwhile, the expression of TGF-β1 and CTGF protein were detected by immunohistochemistry. Results It showed that both E2 and E2-PBCA-NP treatment groups had lower stage of liver fibrosis, according to the observation of pathology by Masson staining (P < 0.05). The anti-liver fibrosis effect of E2-PBCA-NP treatment group was better than that of E2 treatment group (P < 0.05). The mRNA and protein level of TGF-β1 and CTGF were markedly reduced by E2 and E2-PBCA-NP treatment, compared with liver fibrotic model groups (P <0.01). There was no statistical difference between E2-PBCA-NP and E2 treatment (P >0. 05), while no significant change was observed in blank nano -particle group (P > 0.05). Conclusion Both E2-PBCA-NP and E2 had anti-liver fibrosis activity. E2-PB-CA-NP has stronger anti - liver fibrosis activity than E2, which could be resulted from the inhibition of TGF-β1 and CTGF expression.

BACKGROUND:Posterior hip dislocation combined with femoral head fractures easily induced femoral head necrosis, ectopic ossification, osteoarthritis and deep vein thrombosis. Different therapeutic methods should be utilized according to the type of fracture.
OBJECTIVE:To investigate the factors affecting the therapeutic effects and complications fol owing surgery of posterior hip dislocation combined with femoral head fractures.
METHODS:Twenty-eight patients, who had been diagnosed as posterior hip dislocation combined with femoral head fractures in the 101 Hospital of Chinese PLA from September 2004 to May 2010, were enrol ed in this study. According to Pipkin typing, operative approach and the time from injury to surgery, therapeutic effects were evaluated using radiographs and the recovery conditions of hip function (Epstein method), and the occurrence of complications was recorded.
RESULTS AND CONCLUSION:A total of 28 patients were fol owed up from 1 to 5 years, averagely 2.8 years. Using the Epstein method, there were excellent in 6 cases, good in 12 cases, average in 7 cases, and poor in 3 cases, with an excellent and good rate of 64%. The therapeutic effects in patients with Pipkin I and II were good, with excellent and good rates of 100%and 78%, respectively. Moreover, the complications were less, with a rate of 17%and 22%, respectively. The therapeutic effects of patients with Pipkin III and IV were poor, especial y, Pipkin IV patients, whose excellent and good rate was only 20%and the incidence of complications was 80%. No significant difference in the incidence of complications was detected in patients undergoing Smith-Peterson anterior approach and K-L posterior approach (P>0.05). No significant difference in the incidence of complications was detectable among patients from three groups (the time from fracture to operation<12 hours, 12-48 hours, and>48 hours) (P>0.05). Results indicated that the choice of treatment method should be determined by the type of fracture. The prognosis depends on the patient’s age, time of treatment, types of fracture and dislocation, methods of treatment and related measures of prevention of complications.
