OBJECTIVETo explore effective approaches of treating elderly patients with distal tibiofibular fractures.

METHODSFrom August 2008 to October 2012,175 elderly patients with distal tibiofibular fractures were treated with locking compression plate (LCP) through anterior tibial. There were 112 males and 63 females with an average of 71.3 (ranged 60 to 83) years old. Of them,89 cases were treated by anterior tibial tension reduced incision with LCP,including 62 males and 27 females with a mean age of (71.8 +/- 6.4) years old. Eighty-six patients were treated by distal tibial incision with LCP,including 58 males and 28 females with a mean age of (70.3 +/- 6.7) years old. Swelling time, operation time, intraoperative blood loss, hospital stay, healing time, complications and AOFAS scores were compared between two groups after operation.

RESULTSSwelling time in anterior tension reduced incision with LCP and distal tibial incision with LCP was (5.6 +/- 1.3) and (9.7 +/- 2.1) days, healing time was (4.2 +/- 1.4) and (5.4 +/- 1.9) months,and complications were found 3 in tension reduced incision and 10 in distak tibial incision respectively;and all data shown statistically significant differences between two groups (P < 0.05). At 12 months after operation,AOFAS score was 89.0 +/- 9.7, 87.9 +/- 9.4; and there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONTension reduced incision through anterior tibial combined with locking compression plate fixation in treating elderly patients with distal tibiofibular fractures can provide good clinical effects with quick fracture healing and low complications.

Objective To evaluate the feasibility of 3-(4-~(18)F-fluorobenzyl)-8,9-dimethoxy-1,2,3,4-tetrahydrochromeno [3,4-c]pyridin-5-one ( is F-FDTP) as a potential dopamine D4 receptor PET imaging agent.Methods ~(18)F-FDTP solution in ethanol-physiological saline was incubated with calf serum to test its in vitro stability through the determination of radiochemical purity.Normal rats were injected intravenously with ~(18)F-FDTP and then sacrificed at 2,5,10,15,30,60 and 120 min after anesthesia.Blood,organs and brain tissue samples were collected.All samples were weighed and measured for radioactivity.The uptake of samples was expressed as percentage activity of injection dose per gram of tissue ( % ID/g).Results The stability of ~(18)F-FDTP was satisfactory and its radiochemical purity was above 95% after incubation 120 min at 37℃ in calf serum.The biodistribution showed that ~(18)F-FDTP could penetrate through the blood-brain barrier and selectively accumulate in striatum,hypothalamus,frontal certex,hippocampus,cerebellum,where the D_4 receptor was reportedly located.The radioactivities in hippocampus,hypothalamus,striatum,frontal cortex,cerebellum,pons were (0.42±0.03),(0.46±0.05),(0.54±0.04),(0.39±0.04),(0.45±0.06),(0.35±0.04) %ID/g,respectively,2 min post injection.And there was difference between the normal biodistribution results and the blocking experimental results:(0.36 ±0.05),( 0.33±0.05 ),(0.55±0.05 ),(0.30±0.07 ),(0.34±0.07 ) and (0.32±0.04) % ID/g in hippocampus,hypothalamus,striatum,frontal cortex,cerebellum and pons,respectively.Conclusions ~(18)F-FDTP can penetrate through the blood-brain barrier and selectively accumulate in striatum,hypothalamus,frontal cortex,hippocampus,cerebellum,where the D_4 receptor was known to concentrate.These preliminary results suggest that ~(18)F-FDTP is a potential dopamine D_4 receptor imaging agent and further studies are needed.

OBJECTIVETo identify the differentially expressed microRNAs (miRNAs) between esophageal squamous carcinoma (ESC) and adjacent non-tumorous tissue (NT).

METHODSThe expression levels of the miRNAs were detected in 3 fresh ESC and NT samples by hybridization with miRNAs microarray chip. Real-time quantitative RT-PCR was performed to confirm the results of the microarray analysis. The expressions of hsa-miR-126 and hsa-miR-518b in ESC were validated by real-time quantitative RT-PCR in another independent 15 matched samples.

RESULTSA total of 11 miRNAs exhibited differential expressions in ESC samples as compared to their expressions in the NT samples, including a 1 up-regulated miRNA and 10 down-regulated miRNAs. Compared with normal esophageal samples, the ESC tissues showed up-regulated hsa-miR-126 and down-regulated hsa-miR-518b expression.

CONCLUSIONhsa-miR-126 and hsa-miR-518b are differentially expressed in ESC, and they might play important roles in the carcinogenesis and progression of ESC.

Heat-labile enterotoxin (LT) from Escherichia coli is a bacterial protein toxin with an AB5 hexamer structure. LT is a powerful mucosal adjuvant when co-administered with soluble antigens. However, its use in mucosal immunity is inconvenient because of its low yield and depolymerization during long-term storage under normal condition. In this study, we report an efficient expression system and optimized purification and storage strategy of LT. A gene encoding LT was cloned into the vector pET11c and transformed in E. coli BL21(DE3). By growing this strain on modified M9-CAA medium, LT was expressed efficiently. About 46mg/L LT could be purified from the supernatant of bacteria lysate. Using D(+)-Immobilized galactose column, LT could be purified at a wide pH range with various elution buffers. The optimized elution buffers are TEAN (pH 7.3) containing 0.3mol/L galactose and carbonate buffer (pH 10.4) containing 0.3mol/L galactose. After dried by freeze and placed in 4 degrees C, LT dissolved in TEAN (pH 7.3) and carbonate buffer (pH 10.4) were assayed by HPLC. The results indicated that the integrity of AB5 hexamer was kept well. LT could undergo long-term storage under this condition. This was proved to be an optimized strategy of LT storage. The results of GM1 binding assay and toxicity assay showed that the purified recombinant LT has normal biological character.

Parkinson′s disease (PD) is the second most common neurodegenerative disease in middle-aged and elderly people. In addition to motor symptoms, PD also has many non motor symptoms, such as dysosmia, constipation, cognitive impairment, etc. Among them, dysosmia is a common non motor symptom of early Parkinson′s disease. Research has confirmed that olfactory dysfunction (OD) can appear before the typical clinical symptoms of PD, which is of great significance to the diagnosis and treatment of diseases. However, at present, the pathogenesis of OD is still unclear, and the inspection methods have not been unified, and there is no complete cure. This article reviews the latest research progress of dysosmia in Parkinson′s disease.

OBJECTIVETo explore relationship between HBeAg seroconversion with HBV genotypes and HBV specific CTL in patients with chronic hepatitis B (CHB) treated with Adefovir dipivoxil.

METHODSSeventy CHB patients had positive HBV DNA (HBV DNA > or = 1 x 10(4) copy/ml), 45 cases had positive HBeAg, of whom 23 cases (51. 11%) had genotype B, 22 cases (48.89%) had genotype C. ALT > 2 x upper limit of normal value (ULN), human leukocyte antigen (HLA)-A(n) positive, patients were treated with Adefovir dipivoxil (commercial name is Mingzheng, Zhengda Tianjing Pharmaceutical Company), 10 mg, orally, once a day. After treatment for 12 months, observe relationship between HBeAg seroconversion with HBV genotypes and HBV specific CTL.

RESULTSAfter treatment with Adefovir dipivoxil for 12 months, HBV specific CTL (0.68% +/- 0.11%) was higher than that before treatment (0.33% +/- 0.11%), t = 8.36 P < 0.001, HBV DNA (3.01 +/- 0.2) log10 copy/ml was lower than that before treatment (6.27 +/- 0.70) log10 copy/ml, t = 12.63 P < 0.001, HBV DNA turned negative (< 500 copy/ml) 43 cases (61.43%), in 45 cases with positive HBeAg, HBeAg turned negative in 13 cases (28.89%), 8 cases had HBeAg seroconversion (17.78%), HBV specific CTL (0.86% +/- 0.05%) of patients with HBeAg seroconversion is higher than (0.61% +/- 0.07%) of patients without HBeAg seroconversion (37 cases, 82.22%) t = 7.88, P < 0.001. In 8 cases with HBeAg seroconversion, 7 cases had genotype B (30.43% of genotype B), 1 cases had genotype C (4.55% of genotype C), chi2 = 5.15, P < 0.05.

CONCLUSIONAdefovir dipivoxil can enhance HBV specific cellular immunity of CHB patients. After treatment, occurrence of HBeAg seroconversion is related to increase of HBV specific CTL level and may be related to genotypes.

OBJECTIVETo investigate the effect of inversion-table in the treatment of lower pole renal stones.

METHODSFrom March 2006 to September 2008, 36 patients with lower pole renal calculi were treated by inversion-table, 13 cases with stone diameter from 4 mm to 20 mm received extracorporeal shock wave lithotripsy (ESWL) combined with inversion-table treatment and other 23 cases with stone diameter from 2 mm to 4mm received inversion-table treatment alone.

RESULTSAll of 36 cases underwent inversion-table treatment successfully and no one had cardio-cerebral accident. After following up 3 months, the radiologically documented complete stone clearance rate at 3 months group was 83.3%.

CONCLUSIONInversion-table treatment is a safe and valuable adjunct in assisting passage of lower pole renal stone fragments after mini-invasive treatment of stone and can improve stone-free rate.
