Objective To study the genetic susceptibility in patients with postpartum thyroiditis(PPT)by genotyping their human leukocyte antigen(HLA)-DP and -DQ alleles.Methods The polymerase chain reaction-sequence based typing(PCR-SBP)method was used to analyze the distribution of HLA-DPA1,HLA-DPB1,HLA-DQA1 and HLA-DQB1 alleles among 52 PPT patients(31 clinical patients,21 subclinical patients)and 82 healthy controls.Compare the allele frequencies between various patient groups and the control population.Results There was no significant difference between patient group and control group.Conclusion Perhaps PPT is not associated with HLA-DP and HLA-DQ alleles.

Objective To construct a recombinant interfering RNA(miRNA)plasmid vector targeting annexinA3 and observe its impact on the growth and apoptosis of human gallbladder cancer cell line SGC-996.Methods Four small fragments of miRNA and one negative control were sequenced and cloned into vector pcDNATM 6.2-GW/EmGFPmiR.The recombinant plasmids were then transfected into gallbladder cancer cell line SGC-996 by positive liposomal transfection.The transcription and translation level of annexinA3 expression were detected by RT-PCR and Western Blot.Meanwhile, the proliferation and apoptosis of transfected tumor cells were determined by MTT and flow cytometry.Results The recombinant plasmids containing annexinA3 miRNA were successfully constructed.AnnexinA3 expression was significantly knocked down after miRNA plasmid transfection.Transfection of annexinA3 gene miRNA could effectively inhibit the proliferation of gallbladder cancer cell and promote apoptosis.Conclusion AnnexinA3 gene silenced by miRNA can induce the apoptosis of human gallbladder cancer cell line SGC-996.The process might serve as a potential approach for cancer gene therapy.

Objective To investigate the growth and expression of PDGF of VSMCs in response to stimulation of autologous serum and mechanical injury. Methods An vitro model simulating the condition as possible as that after PTA.PDGF of every medium sample from every group was detected by ELISA,and the values of MTT of every cellular sample was measured by MTT to show the growth and proliferation of every group. Results After stimulation by autologous serum and mechanical injury,SMCs of the experimental group showed the value of MTT increasing,but SMCs in control group reached on 3rd day.At the same time,the expression of PDGF also increased gradually,obtaining peak gradually up to peak on day 4/5 nearly 2.0-fold as much as that of SMCs in the control group. Conclusions After on the 5th day,stimulation with autologous serum and mechanical injury,VSMCs of rabbit showed the stronger ability of growth/proliferation,and autocrine of PDGF also increased gradually,reaching peak on 4-5 d,probobly simulating to those in vivo.

Objective To observe the clinical efficacy of Tiao Shen Ding Zhi (mind-regulating) needling method in treating anxious neurosis. Method Fifty-eight patients with anxious neurosis were randomized into a treatment group and a control group, 29 in each group. The treatment group was intervened by Tiao Shen Ding Zhi needling method, while the control group was by conventional needling. The total effective rates of the two groups were observed. Result The total effective rate was 96.5% (28/29) in the treatment group versus 82.8% (24/29) in the control group, and the difference was statistically significant (P<0.05). Conclusion Tiao Shen Ding Zhi needling method can produce a higher total effective rate than conventional acupuncture in treating anxious neurosis.

Objective To observe the clinical features, phenotypes and genotypes in a Chinese family with choroideremia (CHM). Methods A Chinese four-generation family (15 members) with CHM, including 5 patients (4 males/1 female), 2 female carriers and 8 healthy members, was enrolled in this study. Initially all family members underwent best corrected visual acuity (BCVA), indirect ophthalmoscopy, fundus fluorescein angiography, optical coherence tomography (OCT), visual field and full view electroretinogram (ERG). BCVA was followed up for 3 years. Venous blood samples were collected, and all of the 15 coding exons and flanking intron regions were amplified in the proband by polymerase chain reaction followed by direct sequencing. Protein structure was modeled based on the protein data bank and mutations in DeepView v4.0.1 to predict the effect of the mutations. A total of 180 healthy volunteers were enrolled as control group to matching CHM gene sequences. Results The visual acuity (VA) of 3/4 adult male patients began to decrease at less than 10, 10 and 30 years old, the average BCVA was 0.43. There were characteristic signs and symptoms of CHM including narrow visual field, extinguished rod and cone response in ERG, disappeared junction line and intermediate line of photoreceptor inner segment/outer segment on OCT. After 3 years, the mean BCVA decreased to 0.11. The BCVA of one young male patient was 1.0 in both eyes with minor changes fundus and visual field. The VA of the female patient began to decrease at 50 years old, her BCVA of two eyes were 0.5 and 0.25, respectively. The fundus changes were typical of CHM, with relative scotomas in the peripheral visual field of OD, and big scotomas in the OS. After 3 years, her mean BCVA decreased to 0.2. Of 2 female carriers, one had minor fundus changes (patches of pigmentary deposits, atrophy spots of retinal pigment epithelium cells), and the other was normal. A novel heterozygous c.1837G>A mutation in exon 15 of CHM was detected in the proband, which resulted in the substitution of serine by proline at codon 613 (p.D613N). Based on molecular modeling, the misfolded protein caused by the mutation might destabilize the structure of the helix that potentially could affect the global stability of the Rep-1 protein. Conclusions A novel c.1837G>A (p.D613N) mutation may be the causative mutation for CHM in this family. Female CHM carriers may have some signs and symptoms.

Objective To localize the tibial attachment of the posterior cruciate ligament (PCL) on the magnetic resonance imaging (MRI) and provide parameters for clinical PCL reconstruction.Methods We retrospectively analyzed 524 patients with intact tibial PCL attachment who had undergone knee MRI from January 2010 to January 2016.They were 286 men and 238 women with an average age of 35 years (from 20 to 50 years).The size and positions of the tibial PCL attachment were measured on the sagittal and coronal MRI slices.The differences were analyzed between different genders.Results On the sagittal slices,the mean distance from the central tibial PCL attachment to the posterior edge of the tibial plateau was 17.9 ± 3.0 mm and the mean anteroposterior diameter of the tibial PCL attachment was 9.7 ± 2.4 mm,with those for males significantly larger than for females (P ＜ 0.05).The above mean values when expressed as a percentage of the posterior tibial slop were 79.9％ ±4.5％ and 43.7％ ± 9.6％,respectively,showing no significant differences between males and females (P ＞ 0.05).On the coronal slices,the distances from the central tibial PCL attachment to the medial and lateral edges of the tibial plateau were 33.5 ± 3.1 mm and 37.4 ±4.1 mm,respectively,and the mediolateral diameter of the tibial PCL attachment was 12.0 ± 1.6 mm,with those for males significantly larger than for females (P ＜ 0.05).The above mean values when expressed as a percentage of the mediolateral diameter of the tibial PCL attachment were 47.4％ ± 3.2％,52.7％ ±3.1％ and 16.9％ ± 1.7％,respectively,showing no significant differences between males and females (P ＞ 0.05).Conclusions On knee MRI images,the distance from the central tibial PCL attachment to the posterior edge of the tibial plateau is about 17.9 mm,the anteroposterior diameter of the tibial PCL attachment around 9.7 mm,and the mediolateral diameter of the tibial PCL attachment roughly 12.0 mm.These measurements for males are larger than for females.

Objective To investigate and compare the clinical values of serum procalcitonin (PCT)and high sensitivity C-reac-tive protein (hs-CRP)levels for predicting the blood culture positivity in the patients with sepsis.Methods 132 adult patients with sepsis were enrolled in this study.Blood cultures were performed before the antibacterial therapy.The white blood cell (WBC) count,absolute neutrophil count(ANC),levels of PCT and hs-CRP were determined.The application value of PCT and hs-CRP for predicting the positive blood culture results were evaluated.Results The median serum PCT levels in the blood culture positive group and the blood culture negative group were 7.92 ng/mL and 0.95 ng/mL respectively,the difference had statistical signifi-cance(P <0.01).The receiver operating characteristic (ROC)curves showed that PCT had a higher predictive accuracy for blood culture positivity compared with hs-CRP,the area under the curve (AUC)was 0.810(P =0.001)and 0.690(P =0.274),respec-tively.The combined detection of PCT and hs-CRP for predicting the blood culture positive results was similar to the performance of PCT alone,AUC as 0.885 (P =0.001 ).The median cut point of PCT was 0.91 ng/mL,the sensitivity of PCT for predicting blood culture positivity was 90%.This sensitivity remained unchanged when PCT cut point was1.14ng/mL.Using the PCT cut points of 0.91 and 1.14 enabled reducing the submitted blood cultures by 51% and 56% respectively.Conclusion Compared with hs-CRP,serum PCT level could better predict the blood culture positivity in the patients with sepsis.

Objective To compare the protective effect of double dose trimetazidine versus standard dose in patients with unstable angina and received PCI. Methods From September 2014 to June 2015,150 unstable angina pectoris patients who underwent PCI in our hospital were enrolled in this study. All the patients were randomized into two groups:the study group (patients given trimetazidine 40 mg tid 24 hours before operation) and the control group (patients given trimetazidine 20 mg tid 24 hours before operation). All patients received standard secondary prevention therapies of coronary heart disease. Comparison in the rates of angina pectoris attacks, ECG changes after PCI, levels of cardiac troponin I ( cTnI), myoglobin (Mb), creatine kinase isoenzyme ( CK-MB) and hs-CRP before and 12 hours after PCI was investigated between the 2 groups. Results Baseline data were comparable in the 2 groups. Rates of adverse drug reaction were lower in the control group, but the difference was not statistically significant (6. 7% vs. 2. 7% , P = 0. 439). There was no statistical difference between the two groups before PCI in terms of levels of cTNI and hs-CRP but was significantly lowered in the study group after PCI as compared to the control (both P < 0. 05 after PCI). The levels of CK-MB and Mb in the study group were lower than those in the control group after PCI, but the difference was not statistically significant. The rates of angina pectoris attacks and the changes in ST-T were less in the study group as compared to the control group without statistical significance. Conclusions Unstable angina pectoris patients receiving double dose of trimetazidine before PCI may enhance myocardial protection and reduce PCI related myocardial injury.

BACKGROUND: Traditional repair for Achilles tendon rupture has disadvantages of long cast immobilization times, poor outcomes and many complications.OBJECTIVE: To explore the safety and efficacy of early isokinetic rehabilitation training for patients after repair of Achilles tendon ruptures.METHODS: A total of 11 patients with Achilles tendon ruptures received treatments at the Department of Orthopedics, East District of Qingdao Municipal Hospital, from September 2007 to September 2009, were included. Nine of them underwent 8-week isokinetic exercises by using lsomed-2000 at 4 weeks after tendon repair. The evaluative indicators included Arner-Lindholm score, the ankle range of motion, and extensor-flexor peak torque.RESULTS AND CONCLUSION: The follow-up averaged 6 months, ranging from 3 to 12 months. The excellent and good rate of Arner-Lindholm score was 88.9%. The results showed a significant improvement in the ankle range of motion and extensor-flexor peak torque (P < 0.05). There were no infection or re-rupture cases. It is indicated that early isokinetic rehabilitation is safe and effective for patients with Achilles tendon ruptures at 4 weeks postoperatively. It provides evidence for early rehabilitation in patients with Achilles tendon ruptures.
