OBJECTIVE To analyze distribution of the pathogens of catheter-related bloodstream infection ( CRBSI ), and provide doctors with the laboratory evidence of CRBSI diagnosis. METHODS A retrospective analysis of CRBSI pathogens′ distributions from 261 inpatients whose catheter culturing was positive in General Hospital of PLA from Jan 1, 2002 to Aug 31, 2004 was done, and from which true cases of CRBSI were judged and true pathogens or contaminants were identified and counted. RESULTS There were 88 (33.72%) patients diagnosed as CRBSI among 261 cases. They were from intensive care unit (41), surgical department (22), medicine (12), the old patients ward (10), and pediatric ward (3). The first four by rank order of the CRBSI pathogens were Acinetobacter baumannii (15.9%), coagulase-negative staphylococci (14.8%), Pseudomonas aeruginosa ( 11.4% ), and Candida albicans (9.1%). The prominent contaminants were as follows: coagulase-negative staphylococci , Streptococcus pyogenes, Micrococcus and Gram-positive rods. CONCLUSIONS To get a better understanding about distribution of CRBSI pathogens will help its diagnosing as early as possible.

Objective To investigate prophylaxis and therapy of early complications following relatives' partial live small bowel transplantation.Methods Four relatives' partial live small bowel transplantations were carried out.Among the 4 patients,there were 3 cases of short intestine syn- drome and one case of non-function of small bowel caused by the absence of nerve ganglion of small in- testine.More than 4 antigens of HLA were completely matched between donators and receptors.In- testines of donators were got from terminal ileum with the length of (150?10) cm.After operations, tacrolimus (FK506),mycophenolate mofetil (MMF),and methylprednisolone were used to prevent rejections.Measures such as use of anticoagulation,improving microcirculation and albumin infusion, aimed at regulating the function of blood coagulation and preventing bleeding and formation of thrombus at anastomotic stoma;famotidine and omeprazole were used to prevent irritable ulcer;use of the third generation of cephalosporins antibiotics,ganciclovir and fluconazol could prevent bacteria,vi- rus and eumycete infections;disinfection and care of easily-infected organs were emphasized;receptors were encouraged to get out of their beds to move frequently;glutamine and enteral nutrition were used early to promote recovery of intestinal function.Results Three days after operation,one patient's lung was infected with baumanii,and the infection had been under control after being treated with the third generation cephalosporins antibiotics;five days after operation,haematoma was detected on an- other patient and was cleared through the second operations growth of eumycete was found in 2 pa- tients' excretion and secretion from enteron,and their situations were improved with fluconazol;acute rejections of the 4 patients were detected 20 days after operation and reversed by the increased use of FK506 combined with methylprednisolone.Among the 4 patients,2 of them have survived for a long time,and the first patient has survived for 6 years and 8 months till now and the other one for 3 years and 2 months;furthermore,other 2 patients respectively died of infections 5 months and 35 days after the operations.Conclusion Because of special constitution of intestine,early complications of rela- tives' partial live small intestine transplantation are frequent and complicated.Therefore,prophylaxis and therapy of early complications are crucial to the success of the transplantation.
4.Application of Computational Biology to Decode Brain Transcriptomes
Genomics, Proteomics & Bioinformatics 2019;17(4):367-380
The rapid development of high-throughput sequencing technologies has generated massive valuable brain transcriptome atlases, providing great opportunities for systematically investigating gene expression characteristics across various brain regions throughout a series of developmental stages. Recent studies have revealed that the transcriptional architecture is the key to interpreting the molecular mechanisms of brain complexity. However, our knowledge of brain transcriptional characteristics remains very limited. With the immense efforts to generate high-quality brain transcriptome atlases, new computational approaches to analyze these highdimensional multivariate data are greatly needed. In this review, we summarize some public resources for brain transcriptome atlases and discuss the general computational pipelines that are commonly used in this field, which would aid in making new discoveries in brain development and disorders.

The effects of ultrafine grinding on the dissolution rates of the effective components in Sanjie Zhentong capsule (SZC) were studied in this experiment. Fine and ultrafine powder of SZC intermediates were made by ordinary grinding and ultrafine grinding technology, and then granulated by wet granulation. SZC were prepared by fine powder, ultrafine powder and ultrafine granules, respectively. With resveratrol and loureirin B as investigated indexes, dissolution rates of the four intermediates in SZC were determined by cup method and HPLC. The dissolution rates of resveratrol in SZC prepared by fine powder, ultrafine powder and ultrafine granules were 26.11%, 63.27%, 67.49%, respectively; and the dissolution rates of loureirin B were 7.160%, 20.29%, 23.05%, respectively. The dissolution rate of resveratrol and loureirin B in SZC prepared by ultrafine granules was the best. D90 size of ultrafine grinding was 13.221 μm and could improve the dissolution rates of resveratrol and loureirin B in SZC.

OBJECTIVETo observe the impacts on skeletal fluorosis pain, joint motor dysfunction and urine fluoride excretion in the treatment with fire needle therapy, electroacupuncture and calcium carbonate D3.
METHODSThe randomized controlled trial was adopted. Ninety-five patients were randomized into a fire needle group (31 cases), an electroacupuncture group (33 cases) and a calcium carbonate D3 group (31 cases). In the fire needle group and the electroacupuncture group, Ashi points, Dazhui (GV 14), Geshu (BL 17), Quchi (LI 11), Hegu (LI 4), Xuehai (SP 10) points were selected and stimulated with fire needle and electroacupuncture separately, three times a week. In the calcium carbonate D3 group, calcium carbonate D3 tablets was prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months in the electroacupuncture group and calcium carbonate D3 group and 1 month in the fire needle group. VAS score, the range of motion (ROM) and urine fluoride value were compared before and after treatment in the patients of the three groups.
RESULTSAfter treatment, VAS value and ROM were improved significantly in the patients of the three groups (all P < 0.05), the difference was not significant in comparison of the three groups (all P > 0.05). After treatment, the urine fluoride value was increased significantly in the fire needle group [(7.89 +/- 3.61) mg/L vs (9.81 +/- 4.17) mg/L, P < 0.01] and was increased in the electroacupuncture group [(7.53 +/- 3.46) mg/L vs (8.97 +/- 4.21) mg/L, P < 0.05]. The difference was not significant in comparison before and after treatment in the calcium carbonate D3 group (P > 0.05).
CONCLUSIONThe fire needle therapy, electroacupuncture and calcium carbonate D3 all have the clinical value in the prevention and treatment of skeletal fluorosis and the difference in the therapeutic effect has not been discovered among them yet at present. But it has been found that the fire needle therapy and electroacupuncture display the active significance in the promotion of urine fluoride excretion.

OBJECTIVETo observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.
METHODSWe treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.
RESULTSStapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).
CONCLUSIONCircumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.
