Objective To investigate the usefulness of 99Tcm-MDP whole body bone scintigraphy (WBBS) in patients with synovitis,acne,pustulosis,hyperostosis,osteitis (SAPHO) syndrome.Methods 99Tcm- MDP WBBS was performed in 25 patients (6 males,19 females,mean age =(55.1 ±9.8) years)with SAPHO syndrome.Bone lesions were classified into five categories:anterior chest wall,spine,mandible,sacroiliac joint,and limbs.The typical scintigraphic manifestations of SAPHO syndrome were summarized and compared to other radiological imaging data.Results Among 25 patients,32％ of cases (8/25)were associated with skin lesion; 48％ ( 12/25 ) were pathologically diagnosed with chronic nonspecific bone inflammation by bone biopsy.On 99Tcm-MDP WBBS,abnormal metabolic foci at anterior chest wall were found in all cases,most of which located in the sternocostoclavicular region (96％,24/25 ),including sternoclavicular joints (60％,15/25),first costosternal junctions (48％,12/25),and manubriosternal junctions (44％,11/25 ).Only 20％ of the patients (5/25) demonstrated the typical scintigraphic characteristic:“bull's head” sign.The second most frequent part was spine (44％,11/25).Appendicular skeleton was affected in 16％ (4/25) patients.WBBS also demonstrated additional skeletal lesions in 68％ (17/25 ) of the patients,mainly in first costosternal junctions (7 patients),sternoclavicular joints (6 patients),manubriosternal junctions (5 patients) and spine (4 patients).Conclusions Abnormal metabolic foci in sternocostoclavicular region and other imaging manifestations on 99Tcm- MDP WBBS can be used to diagnose,differentiate,and localize the insidious lesion and evaluate the lesion activity in patients with SAPHO syndrome.

This study aimed to analyze the etiology of the encephalitis outbreak in Longyan, Fujian Province, China in 2010, in order to provide valuable information for this prevention and control of this disease. Pathogens were confirmed from cerebrospinal fluid samples with fluorescent RT-PCR, virus isolation (RD cells), and neutralization tests. Then, the VP1 fragments or whole genome nucleotide sequences were determined for four virus strains using PCR. Homology was assessed using the MegAlign software, and a phylogenetic evolutionary tree was drawn using Mega 4.0 software. The results confirmed that the etiology of the outbreak was the ECHO6 intestinal virus, and the nucleotide sequence of the VP1 segment indicated that the C2 subtype was responsible. The genome sequence consisted of 7407 nucleotides, and resembled the genome of other ECHO and CoxB viruses with homology levels of 78.5%-87.3%. The encephalitis outbreak in Longyan in 2010 was caused by the ECHO6 C2 subtype intestinal virus, and its complete genome sequence length is similar to the standard strain (U16283) with a sequence homology of 80.4%.

Objective:To explore the association between interleukin(IL)-28B single nucleotide polymorphisms and natural outcome of hepatitis C virus.Methods:The IL-28B rs12979860 locus was genotyped in 266 HCV infected volunteer blood donors(107 spontaneous cleared and 159 chronic infection) and 97 healthy controls using Sanger sequencing assay.The difference in rs12979860 genotypes and allele frequencies between the six groups(107 spontaneous cleared and 159 chronic infection,266 HCV infection and 97 healthy controls,159 chronic infection and 97 healthy controls) were analyzed by statistics.Results:159 HCV chronic infection,107 spontaneous cleared and 97 healthy controls,were shown more CC genotype,accounting for 83.6%,95.3%and 86.6%,respectively, while the CT genotype accounted for 16.4%,4.7%and 13.4%respectively.No TT genotype was found.The CC/CT genotype was not significant difference between HCV infection and healthy controls,chronic infection and healthy controls(χ2=0.204,P=0.652;χ2=0.406,P=0.524),but between chronic infections and spontaneous clearance had statistically significant(χ2=8.474,P=0.004),the frequence of C allele in spontaneous cleared was higher than HCV chronic infection(χ2=7.949,P=0.005).Conclusion: The gene polymorphism of IL-28B rs12979860 is not related to HCV susceptibility,but there are differences in chronic infection and spontaneous cleared,showing the C allelic in favor of HCV spontaneous cleaed.

OBJECTIVETo investigate the reasonable proposal of prophylactic antibiotics use in selective colorectal operation.

METHODSOne hundred and sixty-five patients underwent colorectal surgery were randomized to Treatment 1 (55 cases), Treatment 2 (50 cases) and Control (60 cases) group. The Treatment 1 group was given oral MgSO4 solution at the night before operation, and Cefradine 2.0 g (I.V.) during the induction of anesthesia, continued with tow times of intravenous Cefradine 2.0 g and 0.5% Metronidazole 100 ml at an interval of 12 hours in 24 hours after the operation. The Treatment 2 group was given the same treatment as Treatment 1, but the antibiotics would not be withdrawn until 3-5 d after operation. On the basis of the treatment of Treatment 2 group, the Control group was given oral antibiotics 2-3 days before operation. Postoperative complications including surgical site infection, stoma leakage, dysbacteriosis, and WBC, body temperature, days of hospitalization and antibiotic expenses in the three groups were observed and compared.

RESULTSThere was no significant differences in surgical site infection, stoma leakage, WBC counting and its change, body temperature and hospital stay among the three groups (P > 0.05). The incidence rate of dysbacteriosis in Control group was significantly higher than that in Treatment 1 group (P < 0.05). The antibiotic expenses in the Treatment 1 group was significantly lower than those of the other two groups (P < 0.05).

CONCLUSIONSProphylactic antibiotic use during the induction of anesthesia and 24 hours after operation was reasonable in selective colorectal operation, it can prevent the surgical site infection effectively with good social-economic effects and fewer side effects.

Objective:To investigate the role of pleiotrophin (PTN) gene in carcino genesis using cDNA microarray and in situ hybridization. Methods:The expression of PTN gene in 5 cases of glioma, 10 laryngeal squamous cell carcinoma, 6 cases of hepatocarcinoma, and normal controls were detected by BioDoor 4096 type cDNA microarray and in situ hybridization. Results: The expression of PTN gene in carcinoma samples were significantly higher than in normal controls by cDNA microarray, the results was the same as by in situ hybridization. Conclusion: cDNA microarray is an effective technique in analysis of functional study of associated genes in carcinoma. High expression of PTN gene might be correlated with mechanism of multiple carcinoma. [

AIM: To observe the clinical efficacy of 25G lens resection combined with anterior vitrectomy in the treatment of congenital cataract.

METHODS: This retrospective case series study included 55 eyes of 38 children with congenital cataract, age from 3mo to 5 years old, who were recruited between May 2013 and August 2017. The children were divided into two groups according to the different surgical methods. Group A(25 eyes of 17 children)received a 25G sutureless lensectomy combined with capsulotomy and anterior vitrectomy, and group B(30 eyes of 21 children)received a cataract phacoemulsification combined with capsulotomy and anterior vitrectomy. The mean follow-up time was 43.4(range: 36-74)mo. The postoperative best corrected visual acuity(BCVA), axial length, and complications were compared.

RESULTS: The age, sex distribution, duration, preoperative BCVA, and preoperative axial lengths were not significantly different between the two groups(P>0.05). The BCVA improved significantly at postoperative compared with BCVA at baseline in both gorups(Group A: P<0.001; Group B: P<0.001). The BCVA was better in Group A than Group B at 6mo postoperatively(P=0.043). No statistically significant difference was found in BCVA between the two groups at 12, 24 and 36mo after initial treatment(P=0.727, P=0.286, P=0.889). No statistically significant difference was found in axial lengths between 6mo of postoperation and preoperation in both groups(Group A: P=0.206, Group B: P=0.082). The mean postoperative axial lengths at 12, 24 and 36mo were longer than that at baseline in both group(Group A: P=0.023, P=0.015, P<0.01, Group B: P=0.018, P<0.01, P<0.01). There were no significantly different in mean axial length after operation between the two groups(6mo: P=0.195, 12mo: P=0.313, 24mo: P=0.485, 36mo: P=0.089). The rate of postoperative complications was lower in Group A than Group B(P=0.042).

CONCLUSION: 25G sutureless lensectomy combined with capsulotomy and anterior vitrectomy is an effective and safe treatment method for congenital cataract, the visual acuity after treatment was improved significantly.

OBJECTIVETo observe voice characteristic of pre-lingual cochlear implant adults for cochlear implantation and phoniatrics.

METHODS3s-sustained voice of vowel [ a: ] of 28 pre-lingual cochlear implant adults, 18 pre-lingual deafness adults and 10 adults with normal hearing were analyzed. Specifically, the Voice analyses include fundamental frequency, first formant, second formant, frequency perturbation quotient (FPQ), amplitude perturbation quotient (APQ) and harmonic noise ratio (HNR). The outcomes of 3 groups were compared.

RESULTSThe fundamental frequency was lower in cochlear implant group [(175.42+/-25. 31) Hz] than that in deafness group [(210.84+/-54.300) Hz] (P = 0.02). The position of formant of cochlear implant group [F2 = (1264. 64 +/- 152.19) Hz] was more access to normal than that of normal hearing group[ F2 = (1422.44 +/- 232. 37) Hz, P = 0. 02]. FPQ of cochlear implant group (2.09 +/- 1.15) was more access to normal than that of deafness group (5.32+/-4.29, P=0.006). The voice of cochlear implanted and deafness adults were much more different individually.

CONCLUSIONSIn the aspect of acoustic characteristic of voice, pre-lingual cochlear implant adults could benefit cochlear implantation finitely. As speech perception of pre-lingual cochlear implant adults was far worse than that of children and post-lingual cochlear implant adults, the general outcome of pre-lingual cochlear implant adults was very limited. Cochlear implant of those candidate should be cautious.

The study was aimed to investigate the effects of bortezomib (BTZ) on the expression of ERK, JNK and P38 in daunorubicin (DNR)-resistant K562 cells (K562/DNR) and to clarify the molecular mechanism of BTZ in reversing the drug-resistance in leukemic cells. The K562/DNR cells and the cellular toxicity of BTZ was determined by MTT, then 4 µg/L of BTZ was chosen to do the experiment. The expression of ERK, JNK, p38 and P-gp of K562/DNR cells treated with DNR only or DNR combined with BTZ for 12, 24 and 36 hours was detected by Western blot. The apoptosis rate in each group was assayed by flow cytometry. The results showed that as compared with DNR group, the expression of P-ERK, P-P38 and P-gp was significantly suppressed (p < 0.05) and the expression of P-JNK was significantly enhanced (p < 0.05) in the cells treated with DNR combined with BTZ. There was no change in the expression of total ERK, P38 and JNK. The effect increased with the prolonging of time. Meanwhile, the apoptosis rate in cells treated with DNR combined with BTZ increased compared with DNR only. It is concluded that the BTZ can reverse the drug resistance in K562/DNR cells by MAPK signaling pathway and increase the apoptosis of leukemic cells. The effect shows the characteristics of time-dependent manner.

The complete genomic sequence of a watermelon isolate of Cucumber green mottle mosaic virus (CGMMV-LN) in Liaoning province was determined and compared with other cucurbit-infecting tobamoviruses. The genomic RNA of CGMMV-LN comprised 6422 nt, and 5'- and 3'- noncoding regions consisted of 59 nt and 175 nt, respectively. The encoded four proteins were two replicase proteins of 186 kD and 129 kD, move protein of 29 kD and coat protein of 17.4 kD. The alignment results of complete nucleotide sequence showed that CGMMV-LN shared identities of 97.6%-99.3% with four other CGMMV isolates, but only shared identities of 61.7%-62.8% with three other tobamoviruses. Homology trees generated from replicase proteins of 186 kD and coat proteins suggested that cucurbit-infecting tobamoviruses could be separated into two subgroups: subgroup I comprising all the isolates of CGMMV and subgroup II comprising Cucumber fruit mottle mosaic virus, Kyuri green mottle mosaic virus and Zucchini green mottle mosaic virus.
