Objective To evaluate the therapeutic effect of ESWL combined with urinary stone decoction and ear acupoint pressure for the patients with renal and ureteral calculi.Methods A total of 110 patients with renal and ureteral calculi were randomly divided into the Chinese medicine (CM) and conventional groups, 55 in each group. Both groups were given ESWL treatment as basic treatment. Chinese medicine group were given the urinary stone decoction and auricular acupressure, and the conventional group used stone granules. Both groups were treated for 2 weeks. According to the photography of ultrasound, the changes of calculi, time of lithagogue, pain relief after operation and the effect rates of pain relief on abdomen and waist, of remission of haematuria, and of urinate pain. ResultsAfter treatment, the successful rates of operation in the CM group was 90.9% (50/55), and conventional group was 76.4% (42/55). There was significant difference between 2 groups (χ2=4.251,P=0.009). The time of stone removal in CM group was significantly shorter than that in the conventional group (7.3 ± 3.8 dvs. 11.2 ± 4.3 d,t=4.032,P<0.001). After 1st, 3rd, 5th, 7th days, the VAS pain scores in the CM group were significantly lower than those in the conventional group (4.1 ± 0.8vs. 5 ± 1.2,t=4.783;4.5 ± 0.9vs. 5.3 ± 1.3,t=4.492; 3.8 ± 0.8vs. 4.5 ± 0.8,t=4.503; 2.2 ± 0.8vs. 2.9 ± 0.9,t=3.691; allP<0.01). After 7th day, the rates of abdominal pain relief was 60% (33/55), pain relief was 79.1% (34/43), the remission of hematuria was 81% (17/21) in the CM group, and the control group were 40% (22/55), 59.6% (28/47), 52% (13/25). There were significant differences between 2 groups on these indices (χ2 values were 4.400, 3.982, 4.217,P values were 0.036, 0.046, 0.040).Conclusions The ESWL combined with urinary stone decoction and ear acupoint pressure could improve the symptoms of patients with kidney ureteral stones.

Background The assessment of total corneal power is essential to both the prediction of intraocular lens power before cataract surgery and the diagnosis of corneal ectasia.Objective This study was to access the repeatability of corneal power measurements in post-laser assisted in-situ keratomileusis (LASIK) eyes with GalileiⅡ dual Scheimpflug analyzer.Methods In this cross-sectional study,68 eyes of 36 subjects who received LASIK surgery more than 3 months in Eye Hospital of Wenzhou Medical University were recruited from July to September in 2011.The mean preoperative spherical equivalent diopter was (-4.95±2.08) D in the subjects with the diopter range from-1.75 D to-10.00 D.The parameters of corneal power were measured by Galilei Ⅱ dual Scheimpflug analyzer,including SimK,Ka,Kp,KG and Kray.Three-time consecutive measurements were completed in every examined eye to obtain the data of SimK,Ka,Kp,KG and Kray,respectively.The coefficient of variation (CV),standard deviation (SD),Cronbach α coefficient and intra-class correlation coefficient (ICC) were calculated to evaluate the repeatability.Concordance between the different measurements was assessed using Bland-Altman agreement analysis.This study followed the Helsinki Declaration,all subjects signed informed consent.Results The CVs of three-time measured SimK,Ka,Kp,KG and Kray were 0.24％,0.28％,-0.37％,0.31％ and 0.32％,respectively,and the Cronbach α values were ＞0.9 and the ICCs were ＞0.982.The Bland-Altman analysis between different measurements showed that the maximum 95％ limits of agreement (LoA) were 0.37 D for SimK,0.46 D for Ka,0.09 D for Kp,0.45 D for KG and 0.49 D for Kray,respectively.Conclusions The Galilei Ⅱ dual Scheimpflug analyzer performed high repeatability and concordance on corneal power measurements in post-LASIK eyes.The differences between measuring results are clinically acceptable.

Objective To investigate the transcription and expression of DNA methyltransferase 1 (DNMT1) mRNA in endemic arsenism patients by burning coal usage,to probe its effects on the development and carcinogenesis of arsenism. Methods In 2008,68 arsenism patients(including 24 mild cases,28 moderate cases and 16 severe cases) were selected in the areas with endemic arsenism according to Standarding of Diagnosis for Endemic Arsenism from Xingren county,Guizhou province. Among the subjects,40 cases were diagnosed by pathological methods,and they were divided into general pathological changes(20),precancerous(14) and cancerous group(6). Tweleve kilometer away from the endemic arsenism area,23 controls were selected in Daguoduo village (non-arsenism exposure). Under the principle of informed consent,blood samples were collected from individuals. The mRNA expression of DNMTI was detected by real-time quantitative reverse transcription polymerase chain reaction(FQ-PCR). At the same time,skin tissue samples were collected from the voluntary surgical treatment patients with endemic arsenism (total 61 cases,including 34 general pathological changes cases,21 precancerous cases and 6 cancerous cases) and from the control(15 cases). DNMT1 protein was detected by immunohistochemical method.Results Average level of DNMT1 mRNA were 0.221 83±0.595 09,0.246 11±0.509 79 and 0.389 27±0.411 33 respectively among mild,moderate and severe arsenism group. DNMT1 mRNA level of mild and moderate group were obviously lower than the control group(0.695 95±0.463 98,all P < 0.01). The mRNA average level of DNMT1 were 0.320 64±0.547 46,0.313 09±0.529 13 and 0.159 07±0.342 56 individually among general pathological changes,precancerous and cancerous group,which were obviously lower than the control group(0.695 95±0.463 98,all P < 0.05). The expression rates of DNMT1 protein in skin were 88.24%(30/34),100%(21/21) and 100% (6/6) among general pathological changes,precancerous and cancerous group were higher than the control group [0(0/15),all P < 0.01],and the extent of expression gradually increased with the aggravation of skin damage(r,= 0.740,P < 0.01). Conclusions DNMT1 participated in the development of the arsenism. High expression of its protein was an early event during the process of the arsenism. DNMT1 may be the new target markers for early diagnosis and treatment of arsenism.

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.

Epigenetics comprises the modifications made in gene expressions without changing the DNA sequence itself. Significant epigenetic changes take place during spermatogenesis and fertilization and exert direct influences on embryogenesis. This article provides an overview of the latest researches on epigenetics of male germ cells and a brief discussion on the correlation of sperm with embryogenesis in four aspects: DNA methylation, histone modification, regulation of non-coding RNAs, and genomic imprinting.

One influenza H3N2 virus, A/swine/Shandong/3/2005 (Sw/SD/3/2005), was isolated from pigs with respiratory disease on a farm in eastern China. Genetic analysis revealed that Sw/SD/3/2005 was a triple-reassortant virus with a PB2 gene from human-like HIN1, NS from classical swine H1NI, and the remaining genes from human-like H3N2 virus. These findings further support the concept that swine can serve as reservoir or mixing vessels of influenza virus strains and maintain genetic and antigenic stability of viruses. Furthermore, we have successfully established a reverse genetics system based on eight plasmids and rescued Sw/SD/3/2005 through cell transfection. HI tests and RT-PCR confirmed that the rescued virus maintained the biological properties of the wild type Sw/SD/3/2005. The successful establishment of the reverse genetics system of Sw/SD/3/2005 will enable us to conduct extensive studies of the molecular evolution of H3N2 influenza viruses in swine.

Objective To explore the efficacy of catheter-directed thrombolysis (CDT) for acute deep venous thrombosis (DVT) of lower limbs.Methods The clinical data of 36 patients with acute DVT of lower limbs treated by CDT form September 2009 to September 2013 were analyzed respectively.Efficacy were assessed through observation of the circumferences,venous patency score and venous patency rate before and after thrombolysis.Results After treated by CDT,the effect of only 1 case with left lower limb DVT associated with inferior vena cava thrombosis was not obvious.The effects of 22 cases were excellence,and 13 cases were good.The total efficiency was 97.2％(35/36).The venous patency scores before and after CDT were (11.85 ± 1.12),(3.6 ± 1.53) points,and there had significant difference (P ＜ 0.01).After CDT,the venous patency rate was (69.6 ± 14.8)％.Conclusion Multi-channel CDT with small saphenous vein for acute DVT of lower limbs is safe and effective,with less invasion and quicker recovery.It is worthy of promotion in clinic.
