Objective To compare the efficacy of sequential therapy combined with probiotics,pure sequen-tial therapy and standard triple therapy for Helicobacter pylori eradication.Methods Selected the clinical data of 240 patients admitted.The 240 patients were randomly divided into 3 groups.Group A received standard triple thera-py,group B received sequential therapy and Group C received sequential therapy in combination with probiotics. Then,we compared the eradication rate,the score of gastrointestinal tract symptoms before and after treatment,and the side effects among 3 groups.Results The eradication rate was 72.5% in groupA,87.5% in group B,and 96.3% in group C.The eradication rate of group C was significantly better than group A and group B (χ2 =18.531,P <0.001).There was no difference in the score of gastrointestinal tract symptoms before treatment(F =0.206,P >0.05),but they all significantly decreased after treatment among 3 groups(P <0.05),with group C a better result(F =25.581,P <0.05).The side effects of 3 groups were 16.3%,13.8%,3.8%,respectively.There were a significantly differencec between group C and the other 2 groups(χ2 =7.011,P =0.030).Conclusion Sequential therapy in combination with probiotics can achieve a higher eradication rate,improve the score of gastrointestinal tract symptoms, and decrease side effects.

Objective To establish an animal model of high-iodine and low-protein in Wistar rats,and to observe the effect of combined excess-iodine and low-protein diet on growth,metabolism and morphological changes in thyroid.Methods According to body weight[(110 ± 10)g] and sex(half male and half female),one hundred and ninety-two Wistar rats,1 month after weaning,were randomly divided into ① normal iodine control group (NI),② 10-fold excess-iodine group (10HI),③ 50-fold excess-iodine group (50HI),④ 100-fold excess-iodine group (100HI),⑤ low-protein control group (LC),⑥ low-protein and l 0-fold excess-iodine group (L10HI),⑦low-protein and 50-fold excess-iodine group (L50HI),⑧ low-protein and 100-fold excess-iodine group(L100HI).Twenty-four rats were in each group,with the experimental period of 6 months.The iodine content of NI and LC groups was 4.65 μg/d; 10HI,50HI and 100HI groups were 46.50,232.50 and 465.00 μg/d,respectively.The animal's body weight,water and feed consumption were recorded weekly.At the end of 60,120,180 days,urine and blood samples were collected from eight rats in each group.Urinary iodine was tested by arseni cerium catalytic spectrophotometry; serum iodine was tested by the method of chloric acid.Histological change of the thyroid gland was observed by transmission electron microscopy and hematoxylin-eosin (HE) staining at the end of 6 months; apoptosis of thyroid was tested by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) method.Results At the end of 4,8,16,18,22 and 24 weeks,the differences of body mass of rats among groups were statistically significant(F =4.26,3.75,4.98,4.09,3.28,3.95,all P ＜ 0.05).At the end of 60,120,180 days,the differences of iodine concentration in urine and blood among groups were statistically significantly (H =5.37,6.03,all P ＜ 0.05).Light microscopy showed that thyroid follicular epithelial cells became flattened,and follicles became distended with colloid following increasing of iodine concentration.Electron microscopy showed increased glial vesicles,condensation of nuclear chromatin,karyopyknosis,and karyolysis with increasing of iodine concentration.The differences of apoptotic indexes among groups were statistically significant (F =4.59,P ＜ 0.01).The apoptotic indexes of L50HI and L100HI groups [(21.50 ± 5.20)‰,(26.70 ± 6.40)‰] were higher than those of 50HI and 100HI groups [(11.20 ± 4.30)‰,(19.40 ± 4.80)‰,P ＜ 0.01 or ＜ 0.05].Conclusion Excessiodine and low-protein can cause growth retardation,abnormal iodine metabolism,and thyroid follicular epithelium damage in Wistar rats.

OBJECTIVE To investigate the feasibility of determining the maximum comfortabl level by using the acoustically evoked stapedius reflex threshold via cochlear implant. METHODS Eleve cases of Nucleus C124 cochlear implant recipients operated in our hospital were selected(8-39 years old, who can decide TIC value by themselves with the postoperative time ranging from device initiation to 1 year after operation),of those four cases were diagnosed as bilateral large vestibular aqueduct syndrome,1 case as common cavity dysplasia,.neural response telemetry of these five patients with inner ear dysplasia were very high or barely measurable.Real-MCL level and acoustically evoked stapedius reflex threshold under activated condition were measured respectively. The stimulating sound was 110dB of white noise.RESULTS The two group values of ASRT and real-MCL were found to be consistant .There is no significant difference statistically (P＞0.05). The thresholds of ASR increase with the increasing of real-MCL at the beginning of device initiation. CONCLUSION The acoustically evoked stapedius reflex threshold may reflect (ASRT) the maximum comfortable stimulation level under activated conditions in patients with cochlear implants.it is simple, reliable and may be used to determine the MCL of child cochlear implanted patients.

Cassiae Semen is a common traditional Chinese medicine, and contents of anthraquinones of Cassiae Semen different significantly from area to area. According to Chinese Pharmacopoeia (2010 edition), only contents of aurantio obtusin and chrysophanol were used to evaluate the quality of Cassiae Semen, another data could be added later. Ten batches of Cassiae Semen from different areas were determined, and total anthraquinones, total free anthraquinones and total combined anthraquinones contents were assessed by ultraviolet visible spectrophotometer, contents of aurantio obtusin, rhein, aloe emodin, emodin, chrysophanol and physcion were determined by HPLC. After that, principal components analysis was used to evaluate these data determined previous by dimension reduction analysis. At last, the result suggests that three main components were found out, it shows that content of aloe emodin could be used to evaluate the quality of Cassiae Semen as well as contents of aurantio obtusin and chrysophanol. And Cassiae Semen from Hebei province posseses higher quality than Cassiae Semen from other different areas. All these results can provide a good reference for quality evaluating of Cassiae Semen medicinal materials at a certain extent.

OBJECTIVETo investigate the clinical effects of close reduction and minimally invasive percutaneous plate osteosynthesis in treating proximal humerus fractures in the aged.

METHODSFrom February 2012 to December 2013,39 patients with proximal humerus fractures were treated with minimally invasive percutaneous plate osteosynthesis (MIPPO group, 21 cases) and open reduction internal fixation (ORIF group, 18 cases). Including 17 males and 22 females in the study, and aged from 67 to 88 years old with an average of (71.8 ± 5.2) years old. In MIPPO group, there were 11 males and 10 females with an average age of (70.0 ± 5.3) years old;and in ORIF group, there were 10 males and 8 females with an average age of (72.0 ± 4.2) years old. Operation time, blood loss during operation, fracture healing time and postoperative complications were recorded. The functions of the shoulder joints were assessed according to Constant-Murley score at final follow-up.

RESULTSAll the patients were followed up from 11 to 27 months with an average of 18.1 months. The mean blood loss of the MIPPO group was (176.0 ± 57.4) ml,while the ORIF group was (356.0 ± 66.9) ml (t = 7.22,P = 0.01). The operation time of the MIPPO group was (47.4 ± 14.9) min, while the ORIF group was (92.7 ± 15.8) min (t = 0.79, P = 0.03). Fracture healing time in the MIPPO group and ORIF group was (17.6 ± 5.8), ( 21.7 ± 4.9) weeks, respectively (P < 0.05). The mean Constant-Murley score at final follow-up was 89.7 ± 14.5 in MIPPO group, and 81.8 ± 13.2 in ORIF group (P < 0.05).

CONCLUSIONMIPPO has advantages of little trauma, less blood loss, rapid recovery, less vascular damage and so on and can effectively treat the proximal humerus fracture in the aged.

Objective To investigate the expression of Phosphorylated-signal transduction and activators of transcription 3 (P-STAT3) proteins in human prostate tissue from patients received re-peated biopsies. And consider the usefulness of detecting expression of P-STAT3 in early diagnosis of prostate cancer (PCA). Methods Fifty-eight patients (29 cases of PCA, and 29 cases of benign prostatic hyperplasia (BPH)) who had received repeated biopsies were involved in this study. Immu-nolabelling has been carried out on PCa patients' samples of cores from initially negative biopsies, typ-ical cores from cancer field, and other cores of the same batch biopsies showing no sign of prostate cancer. BPH patients' samples of cores from initial biopsies were set as control. All specimens were done immunohistochemistry stain with anti-P-STAT3 monoclonai antibody. The association of P-STAT3 expression in prostate tissues with the pathology result was evaluated. Results Compared with 10.3% in specimens of patients free of prostate cancer, the positive rate of anti-P-STAT3 stained in typical cores from cancer field, other cores of the same batch biopsies showing no sign of prostate cancer, and cores from initially negative biopsies, was 93.1 % (27/29), 82.8 % (24/29) and 86.2 % (25/29), respectively. There were significant differences of these values between former and laters' (X2=60.123,P=0.000). If P-STAT3 positive in tissue of initially biopsies was considered as the di-agnostic standard of prostate cancer, then it would show a relatively high sensitivity (86.2%) and specificity (89.7%). Conclusion IHC stain for P-STAT3 in prostate biopsy samples could be served as an adjunct to the current diagnostic approach to prostate biopsy for early diagnosis of pros-tate cancer.

Objective To understand the schedule and effectiveness of water-improving defluoridation projects comprehensively of control of fluorosis in drinking-water-borne endemic fluorosis areas in Shandong Province,and to provide a scientific basis for making strategies for prevention and control of the disease.Methods In accordance with the requirements of Shandong Provincial Survey Scheme for Implementation of Prevention and Control Measures of Endemic Fluorosis,the progress of water-improving defluoridation projects was investigated in Shandong Province.The types of water source,scale and operating conditions for water-improving defluoridation projects in 17 cities of the province were investigated.Water fluoride contents of the normal operating projects were detected by F-ion selective electrode.Results ① By the end of 2012,a total of 3 539 water-improving defluoridation projects were built that covered 9 856 fluorosis villages,113 counties,17 cities in the province,and the water-improving rate was 91.01％ (9 856/10 830).The type of water source of water-improving project was mainly groundwater,accounted for 93.78％ (3 319/3 539) of the total projects.As for the scale of the water-improving projects,small centralized water supply projects were the main projects,accounted for 92.96％(3 290/3 539) of the total projects.\)Of all the water-improving defluoridation projects,normal operating projects accounted for 89.12％(3 154/3 539),intermittent and scrapped projects accounted for 3.25％(115/3 539) and 7.63％ (270/3 539),respectively.③Among normal operating projects,the number of projects with water fluoride content ≤ 1.20 mg/L was 1 925,accounted for 72.40％(1 925/2 659).The number of projects with water fluoride content ＞ 1.20 mg/L was 734,accounted for 27.60％ (734/2 659); among them water fluoride contents between 2.01-4.00 mg/L and ＞ 4.00 mg/L were 233 and 65,respectively,and the highest water fluoride value was 9.71 mg/L.Conclusions The progress of water-improving projects in some cities (counties) of Shandong Province is still slow.Some of the water-improving projects can not be operated normally or have been scrapped,and water fluoride content has exceeded the standard seriously.So the prevention and control measures need to be further strengthened,funding should be increased,and the operating conditions and water quality of the water-improving defluoridation projects in Shandong need to be further improved.

OBJECTIVE To find the best way to evaluate the hearing threshold with the objectivethresholds of auditory brainstem response(ABR) and 40Hz auditory event related potential(40Hz AERP) . METHODS Pure tone audiometry,ABR and 40Hz AERP detection were performed in 120 recipients from whom 86 ears were available to be analyzed. According to the styles of configuration of hearing,we divided the 86 ears into 3 groups. There were 37 ears in flat style group,29 ears in descent style group,20 ears in ascent style group. The values were statistically analyzed with SPSS software. Correlations and multiple linear regression analysis were used in each group separately and three kind of mathematic models were established to estimate the subjective auditory thresholds. Then the models were simplified and tested. At last the models were checked out in 10 new recipients separately. RESULTS The pure tone audiometric threshold had good liner correlations with ABR and 40Hz AERP in three groups(R2=0.932,0.944,0.934) . In the flat style group,the subjective average auditory threshold can be estimated by ABR threshold. The predict mathematic model of the descent style group was 1/3(40HzAERP) +2/3ABR and the model of the ascent style group was 2/3(40HzAERP) +1/3ABR. Mean square deviation test showed equation manners were better than ABR means. CONCLUSION We can predict the subjective average auditory threshold more accurately than ABR only from ABR threshold and 40Hz AERP values with the predict mathematic models in young child and patients difficult to be test with subjective audiometry.
