Chinese Journal of Nursing 2009;44(8):711-712
This paper introduces the perioperative nursing of 20 cases of branchial cysts in newborn with cyst extraction. The nursing care focused on body position,respiratory care,diet management and wound care,which alleviated the patients' dyspnea,prevented respiratory aspiration and promoted wound healing. All the 20 newborn recovered well without recurrence in the four years after the operation.

BACKGROUND:Ligustrazine can effectively prevent and treat peritoneal adhesion and adhesive ileus after surgical treatment. OBJECTIVE:To prepare Ligustrazine nanoparticle spray which is prepared to achieve sustained release and improve clinical efficacy and to explore its optimal dose for preventing experimental peritoneal adhesions in rats. METHODS:Eighty rats were randomly divided into five groups:model group, sodium hyaluronate group, high-, medium-and low-dose Ligustrazine nanoparticle groups, with 16 rats in each group. After peritoneal adhesion model was established with rasp method, model group was immediately subject to abdomen-closing, while sodium hyaluronate group and Ligustrazine nanoparticle groups received sodium hyaluronate smearing and Ligustrazine nanoparticle spray (2.5, 5, 10 mg/kg), respectively. Al rats were kil ed at 1 and 2 weeks after modeling, to observe adhesions. The adhesion score was recorded. The adhesive tissue sections were stained with hematoxylin-eosin for pathological changes. The level of transformation growth factor-β1 in peritoneal fluid of rats was detected with ELISA assay. RESULTS AND CONCLUSION:Ligustrazine Nanoparticle spray had a sustained release effect, and prolonged the duration of action of drugs, thus achieving a better anti-adhesion effect post-surgery. The medium-and high-dose Ligustrazine nanoparticle sprays exhibited better anti-adhesion effects, and improved the rise of transformation growth factor-β1 level in the peritoneal fluid. As the drug concentration is low, the intraperitoneal administration in a spray manner is preferred. Because the total dose is limited, we define the optimal effective dose as 5 mg/kg.

Objective To assess clinical outcomes of FasT-Fix technique in repair of meniscal injury under arthroscope. Methods A total of 36 cases (37 knees) of mensical tears were repaired with FasF-Fix technique. There were 26 males and 10 females, at mean age of 26 years (14-51 years). Eighteen meniscal tears were located in zone Ⅱ, 16 in zone Ⅲ and 3 in zone Ⅳ. The average length of the tear was 2.2 cm (1.0-3.0 cm). Results There were no any signs of early complications after sur gery. All cases were followed up For 6-26 months (mean 16 months). According to Lysholm scoring scale system ,the average score of operated knees was increased from preoperative 44.13+12.56 to postopera tive 80.24+12.67 (P<0.01). After operation, all the patients could move the knee joint at normal range, except for one case who had a limitation of 20 degree flexion, with no pain or interlocking symptom. All cases returned to original work and/or could continue sports game. Conclusion The FasT-Fix technique is a simple, safe and effective method for repair of properly selected meniscal tears.

Objective To explore the correlation between the levels of liver fibrosis and liver fibrosis biochemical parameters of advanced schistosomiasis patients. Methods A total of 48 advanced schistosomiasis patients were investigated and they were examined by the liver biopsy and B ultrasound imaging. At the same time,the liver fibrosis biochemical parameters,including glu-tamine transpeptidase(GGT),alkaline phosphatase(AKP),procollagenⅢ(PC-Ⅲ),collagen typeⅣ(Ⅳ-C),hyaluronic acid (HA)and laminin(LN),were detected. The liver fibrosis levels were classified by the liver biopsy and B ultrasound imaging,re-spectively,and the correlation between the levels of liver fibrosis and liver fibrosis biochemical parameters were analyzed statisti-cally. Results There was no correlation between the liver fibrosis levels classified by the liver biopsy and all the liver fibrosis bio-chemical parameters;there was a weak correlation between the liver fibrosis levels classified by the B ultrasound imaging and GGT,AKP,LN and PC-Ⅲ,respectively;there was a significant correlation between the liver fibrosis levels classified by the B ul-trasound imaging and HA andⅣ-C,respectively. Conclusions B ultrasound examination is a better,noninvasive fibrosis in-spection method. Liver fibrosis biochemical parameters combined with the B ultrasound examination may better reflect the overall condition of liver fibrosis.

Objective To analyse the expression and significance of CD44 variant (CD44v17) in the process of cervical intraepithelial neoplasia (CIN) to cervical cancer,and to explore the relationship of CD44v17 with CIN and cervical cancer.Methods The expressions of CD44v17,matrix metalloproteinase 9 (MMP9) and Ki67 in normal cervical tissue,CIN Ⅰ,Ⅱ,Ⅲ and cervical carcinoma tissues were detected by real-time quantitative RCR.The expressions of CD44v17,MMP9 and Ki67 in human cervical cancer cell lines HeLa and SiHa after transfecting with CD44v17 siRNA were detected,as well.The tumor-bearing nude mice were treated with lentivirus particles of CD44v17,and the influence of CD44v17 siRNA on tumorigenicity in nude mice was analysed.Results The expression level of CD44v17 increased gradually from CIN Ⅰ,Ⅱ,Ⅲ to cervical carcinoma tissues.Compared with normal cervical tissue,the expression levels of CD44v1 7,MMP9 and Ki67 were significantly increased in CIN Ⅱ,Ⅲ and cervical carcinoma tissues (P<0.05),while no significant difference was found between normal cervical tissue and CIN Ⅰ tissue (P>0.05).The expression levels of MMP9 and Ki67 in human cervical cancer cell lines HeLa and SiHa were decreased significantly after transfecting with CD44v17 siRNA (P<0.01).The tumor volume and weight were decreased by treatment with CD44v17 siRNA transfection (P<0.01),and the tumorigenicity in nude mice was decreased.Conclusion CD44v17 may promote the development of CIN to cervical cancer.It is expected to be an indicator in predicting malignant potential of CIN.

OBJECTIVE:
To explore the genetic basis for a girl featuring epilepsy, developmental delay and regression.
METHODS:
Clinical data of the patient was collected. Activities of hexosaminidase A (Hex A) and hexosaminidase A&B (Hex A&B) in blood leukocytes were determined by using a fluorometric assay. Peripheral blood samples were collected from the proband and six members from her pedigree. Following extraction of genomic DNA, whole exome sequencing was carried out. Candidate variants were verified by Sanger sequencing.
RESULTS:
Enzymatic studies of the proband have shown reduced plasma Hex A and Hex A&B activities. Genetic testing revealed that she has carried c.1260_1263del and c.1601G>C heterozygous compound variants of the HEXB gene. Her mother, brother and sister were heterozygous carriers of c.1260_1263del, while her father, mother, three brothers and sister did not carry the c.1601G>C variant, suggesting that it has a de novo origin. Increased eosinophils were discovered upon cytological examination of peripheral blood and bone marrow samples.
CONCLUSION
The compound heterozygous variants of c.1260_1263del and c.1601G>C of the HEXB gene probably underlay the Sandhoff disease in this child. Eosinophilia may be noted in infantile Sandhoff disease.

Methods:
Retrospectively analyze the clinical characteristics and prognostic factors of 89 patients with BCR-ABL positive ALL from April 2012 to June 2018 in our hospital, the clinical efficacy of first-generation and second-generation TKI was compared.
Results:
60 patients were classified into the first-generation TKI (imatinib) group, and 29 patients were in the second-generation TKI (dasatinib) group. There were no significant differences in gender, age, WBC, hemoglobin concentration, PLT, chromosomal karyotype, the types of fusion genes, allogeneic hematopoietic stem cell transplantation (allo-HSCT) and TKI initiation time between the two groups. The first-generation and second-generation TKI groups, for which the complete remission (CR) rate at the fourth week of induction therapy was 83.3% and 89.7% (
