Muscular dystrophies (MD) comprise a heterogeneous group of hereditary myopathic diseases. In this group, myotonic MD is associated with an increased cancer risk. However, the cancer risk in other types of MD is unclear. To address this gap in knowledge, we assessed data obtained from the Taiwan Health Insurance Program database. A total of 1,272 patients with MD diagnosed between 1997 and 2009 were enrolled. They were followed up for cancer during the same period by record linkage with the cancer certification in Taiwan. Age- and sex-standardized incidence ratios (SIRs) of overall and site-specific cancers were calculated. For congenital and progressive hereditary MD, there were 685 and 505 cases (males: 69.5% and 80.6%), the median ages at diagnosis were 16 and 13 years, and the mean follow-up durations were 7.12 and 5.06 years, respectively. In addition, cancers were developed in 10 patients with congenital MD and 3 patients with progressive hereditary MD. Female MD patients exhibited an increased cancer risk, yielding an SIR of 3.37 [95% confidence interval (CI) = 1.38-8.25] in congenital MD and 2.95 (95% CI = 0.95-9.19) in hereditary progressive MD. Site-specific cancer SIRs were not powered to be significantly different. In conclusion, genetic defects in hereditary MD may increase cancer risks in females and a sex difference should be further investigated.

Background: Health-care providers typically undergo shift work and are subjected to increased stress. Night shift work may induce disturbed sleep cycles and circadian rhythm. The objective of this study was to explore if night shift workers (NSWs) show an increased risk of abnormal thyroid-stimulating hormone (TSH). Methods: We conducted a retrospective cohort study of 574 employees without thyroid disease and abnormal TSH at baseline who underwent annual check-ups between 2007 and 2016 in a medical center. NSWs were defined as those with working time schedules other than daytime hours. We calculated the incidence rate and estimated the adjusted hazard ratio (HR) for incident abnormal TSH and subclinical hypothyroidism compared with non-NSWs using a Cox regression model. Results: A total of 56 incident abnormal TSH cases and 39 subclinical hypothyroidism cases in NSWs were identified during 3000 person-years of follow-up. In models adjusted for age, sex, obesity, and working departments, we found no increased relative risk for incident abnormal TSH (HR: 0.72, 95% confidence interval: 0.33–1.60) or subclinical hypothyroidism (HR: 0.52, 95% confidence interval: 0.19–1.45) when comparing NSWs to non-NSWs; nor were incidence rates significantly different among exclusively medical employees after excluding administrative staff. Conclusion In this hospital-based nine-year follow-up retrospective cohort study, NSWs were not associated with increased relative risk of incident abnormal TSH and subclinical hypothyroidism, in contrast to previous cross-sectional studies.

BACKGROUND/AIMS: With the recent progress in medical treatment, surgery still plays a necessary and important role in treating ulcerative colitis (UC) patients. In this study, we analyzed the surgical results and outcomes of UC in Taiwan in the recent 20 years, via a multi-center study through the collaboration of Taiwan Society of IBD. METHODS: A retrospective analysis of surgery data of UC patients from January 1, 1995, through December 31, 2014, in 6 Taiwan major medical centers was conducted. The patients' demographic data, indications for surgery, and outcome details were recorded and analyzed. RESULTS: The data of 87 UC patients who received surgical treatment were recorded. The median post-operative follow-up duration was 51.1 months and ranged from 0.4 to 300 months. The mean age at UC diagnosis was 45.3±16.0 years and that at operation was 48.5±15.2 years. The 3 leading indications for surgical intervention were uncontrolled bleeding (16.1%), perforation (13.8%), and intractability (12.6%). In total, 27.6% of surgeries were performed in an emergency setting. Total or subtotal colectomy with rectal preservation (41.4%) was the most common operation. There were 6 mortalities, all due to sepsis. Emergency operation and low pre-operative albumin level were significantly associated with poor survival (P=0.013 and 0.034, respectively). CONCLUSIONS: In the past 20 years, there was no significant change in the indications for surgery in UC patients. Emergency surgeries and low pre-operative albumin level were associated with poor survival. Therefore, an optimal timing of elective surgery for people with poorly controlled UC is paramount.

OBJECTIVESTo compare short-term and long-term change of paraspinal muscle between percutaneous and open pedicle screw fixation in the treatment of thoracolumbar fractures.

METHODSThirty-three patients were divided into four groups: short-term percutaneous pedicle screw fixation group, short-term open pedicle screw fixation group, long-term percutaneous pedicle screw fixation group, and long-term open pedicle screw fixation group. Paraspinal muscle were studied by needle electromyography and CT. Cross-sectional area and color grade information of paraspinal muscle were measured using CT image.

RESULTSThe area and color grade of paraspinal muscle changed significantly after surgery. The color grade of paraspinal muscle showed significant change while the muscle area observed no significant change in the two short-term groups; There was significant change in paraspinal muscle area, however no significant change was found in muscle color grade of the two long-term groups. In electromyography study the results showed that there was significant difference in the two short-term groups, however no significant difference existed in the long-term groups. There was no significant difference of patients treated by the two surgical technique in long-term function evaluation.

CONCLUSIONBoth percutaneous and open pedicle screw fixation damage paraspinal muscle, however the muscle showed less injury treated by percutaneous pedicle fixation.

OBJECTIVETo study the effect of lycopene on red blood cell and the level of blood lipid.

METHODSAccording to the level of serum total cholesterol and weight, forty-eight adult male SD rats were divided randomly into six groups: normal control (group A), fed by normal feed; hyperlipidemia group (group B): fed by high fat diet; positive control group (group C): fed by high fat diet plus 10 mg * kg(-1) * d(-1) fluvastatin sodium; lycopene groups: fed by high fat diet plus 11 (group D), 22 (group E), 44 mg * kg(-1) * d(-1) (group F) lycopene through gavage, respectively. For all six groups, the level of serum total cholesterol (TC) and total triglyceride (TG) were measured at the end of 0, 1, 3 weeks of the study by taking samples from tail vein. At the end of the experiment, RBC and HGB were measured.

RESULTSAfter the rats were fed with high-fat feed for a week, models of hyperlipidemia rats were established. At the end of 3 weeks, TC of group A, B, C, D, E and F were (1.31 +/- 0.05), (19.40 +/- 0.54), (4.66 +/- 0.07), (7.18 +/- 0.06), (5.30 +/- 0.28), (4.49 +/- 0.23) mmol/L (F = 4395.72, P = 0.00), respectively;and TG were (0.42 +/- 0.01), (2.29 +/- 0.42), (0.69 +/- 0.03), (1.10 +/- 0.05), (0.63 +/- 0.02), (0.62 +/- 0.04) mmol/L (F = 127.26, P = 0.00), respectively; HGB were (143.13 +/- 6.33), (112.63 +/- 2.56), (124.75 +/- 3.62), (124.63 +/- 7.78), (132.38 +/- 6.41), (142.13 +/- 5.54) g/L (F = 34.14, P = 0.00), respectively; RBC were (6.75 +/- 0.60) x 10(12)/L, (5.08 +/- 0.75) x 10(12)/L, (7.14 +/- 0.82) x 10(12)/L, (5.94 +/- 1.09) x 10(12)/L, (6.18 +/- 0.36) x 10(12)/L and (7.31 +/- 0.58) x 10(12)/L (F = 10.35, P = 0.00), respectively.

CONCLUSIONLycopene have some protective effects on red blood cells of the hyperlipidemic rats by regulating the blood lipid and antioxidant.

In view of the increasing number of patients undergoing kidney dialysis or transplant every year, a survey of the literature on renal protective medicinal plants was undertaken. Most of them are from traditional Chinese medicine (TCM). Although many of the medicinal herbs reported have not been investigated in terms of active chemical ingredients, some do have compounds well characterized. They fall into a wide range of structures. Several groups of compounds with well established activities are discussed. These include: antioxidant phenolic compounds like tannins, flavonoids, isoflavonoids, unsaturated organic acids and lignans; circulation enhancing compounds like saponins, and basic alkaloids with multiple targets (G-protein coupled receptors). Also presented are proinflammatory and antiinflammatory fatty acids like linoleic (n-6) and α-linolenic (n-3) acids, respectively. Attention is also drawn to the plants containing nephrotoxic aristolochic acid. Different directions of future research are also presented. We hope that this review may provide some leads for new drug discovery and development, and more rational application of TCM.

OBJECTIVETo introduce the technique of minimally invasive percutaneous pedicle screws osteosynthesis (MIPPSO) and compare the preliminary clinical outcomes of the treatment of thoraco-lumbar vertebra fracture with traditional open pedicle screws osteosynthesis (TOPSO).

METHODSUsing the "C" arm fluoroscopic guidance, the pedicle screws were put through new-designed instrumentation and inserted percutaneously with fifty cases of thoraco-lumbar vertebra fracture. Semi-Laminectomy were made in the heavy-occupation side through the incision of 4 cm. Vertebroplasty were made through pedicle of disease vertebrae. perioperative parameter and the index of image were compared with the treatment of traditional open pedicle screws osteosynthesis in other fifty cases.

RESULTSThe consumed time of operation in the MIPPSO group and the TOPSO group made no significant difference (P >0.05), but the length of incision, injury of paraspinal muscles, bleeding of operation, drain of postoperation, pain of postoperation, spending time of hospitalization were all significantly different between the two group (P <0.05). Each group compared to itself between preoperation and postoperation, the vertebral height, the height of intervertebral disk, Cobb's angle and the occupation index of vertebral canal were all significantly different (P <0.05). however compared to each other, whether preoperation or postoperation, there were not significant different in the index of image (P >0.05).

CONCLUSIONSThe technique of minimally invasive percutaneous pedicle screws osteosynthesis (MIPPSO) has the advantages of simple manipulation, safety, small trauma, less bleeding, light pain, quickly recovery and short hospitalization time.

Objective To establish the feasibility of performing an endoscopic anterior approach for upper cervical spine in a clinical setting.Methods Application of this method on 13 Chinese cadavers was conducted to verify the practicability of this technique.Anatomic data were obtained by measuring the anterior cervical specimens,and anatomic observation was conducted in the neighboring structure through below the su- perior thyroid artery.Results The superior thyroid vascular-nerve plexus was neighbor to the puncture can- nula.But there has a quite large distance between the hypoglossal,the glossopharyngeal,the lingual artery, the external branch of the superior laryngeal nerve and the puncture cannula.There has enough space between the posterior wall of the pharynx and the prevertebral fascia to put the MDE canuula.Conclusion This ca- daver and clinical study demonstrates that an endoscopic anterior approach to the upper cervical spine is safe and feasible,and can be a valid alternative to the conventional transoral approach.

Objective: To understand the epidemiological characteristics and antibiotic resistance profiles of Campylobacter spp. in Shanghai from 2013 to 2016. Methods: Stool samples collected from diarrhea outpatients were cultured for Campylobacter spp., using the membrane filter method in 23 hospitals under the sentinel programs, from 2013 to 2016. All the strains were identified by biochemical tests and PCR. Broth microdilution method was used to investigate the antibiotic resistance of 179 Campylobacter spp. strains that including azithromycin, ciprofloxacin, erythromycin, gentamicin, tetracycline, nalidixic acid, telycin, klinthromycin and flurbenicol. Results: A total of 179 Campylobacter spp. strains were isolated from 10 444 stool samples (1.7%). Campylobacter jejuni and Campylobacter coli appeared as the predominant ones (94.4% and 5.6%). The incidence rate was higher in children than that in adults, with peaks of infections mainly from April to June and October to December. Campylobacter jejuni strains seemed highly resistant to ciprofloxacin (96.4%), tetracycline (83.4%) and nalidixic acid (81.7%). The resistant rates appeared higher on Campylobacter coli strains that isolated from patients. Some strains were resistant to multi-drugs. Conclusions Campylobacter spp. seemed one of the important pathogens that isolated from outpatients with diarrhea, in Shanghai. Both age and season related characteristics of Campylobacter spp. were seen. Campylobacter spp. isolated from patients was highly resistant to ciprofloxacin, tetracycline and nalidixic acid.
