Objective To investigate the effect of Mepilex on pressure sores in patients at lateral position after craniocerebral surgery.Methods Toally 60 patients lying at lateral position after craniocerebral surgery were randomized into two groups in equal number with random digit table:the control group and experiment group.In the control group,Gel pad was used to prevent and treat the pressure sores and in the experiment group Mepilex was used between the compressed skin and operation table before setting the position.The skin conditions of the two groups were observed after operation.Result The prophylactic effect of pressure sore in the experiment group was significantly better than that in the control group (P＜0.05).Conclusion Mepilex can prevent the skin pressure sores in the patients at lateral position after cerebral surgery.

OBJECTIVE:To provide suggestions for the improvement of eye drops specifications(EDS)so as to promote safe and effective use of eye drops.METHOD:123kinds of EDS in18categories in our hospital pharmacy were investigated and analyzed.RESULTS:Several important contents in the specifications like pharmacology and toxicology,pharmacokinetics,ad-verse reactions,contraindications,precautions,medications for pregnant and nursing women,and that for children and senile patients,drug interactions and overdose failed to fully meet the national criteria.The quality of the imported EDS was superior to that of the domestic EDS.CONCLUSIONS:The EDS were still far from being perfect and improvement of which is neces-sary so that more detailed drug information is available for physicians,pharmacists and patients,which is conducive to safe and effective use of drugs.

Objective To evaluate the role of multiple dorsal midline plication (MDMP) procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient.Methods From September 2010 to July 2013,33 postpubertal patients with Donnahoo type Ⅲ chordee (＞ 20°) were treated with MDMP procedure.The age ranged from 18 to 37 years with an average of 29 years.Primary surgery was indicated in 18 patients including type Ⅲ chordee in 11 and type Ⅲ/Ⅳ in 7,with associated hypospadias in 12.Redo surgery was warranted in 15 patients including type Ⅲ chordee in 13 and type Ⅲ/Ⅳ in 2,with associated urethral defects necessitating repair in 12.Intraoperative artificial erection was induced to confirm the degree and length of chordee.Longitudinal plication sutures,4 dots each,were applied close to the midline in a parallel fashion on each apex of curvature,to achieve satisfactory orthoplasty with 16-dot to 64-dot plication according to the chordee status,and the urethral repair indicated was achieved simultaneously.Results Satisfactory orthoplasty was achieved with 16-dot plication in 16 patients,24-dot in 10,32-dot in 6,and 64-dot in 1 patient whose penile curvature was severe and long.Followup was obtained from 35 to 69 months with an average of 46 months.Three patients lost of followup.Urethroplasty-related complications were noted in 5 patients including urethrocutaneous fistula in 2,urethral dehiscence in 1,urethral diverticulum in 1,and urethral stricture in 1.Mild cicatrical curvature (less than 15 degree) was noted in 2 patients.No postoperative priapism,erectile dysfunction,and paraesthesia was noted,nor chordee recurrence.Conclusions When applied appropriately,MDMP is an effective procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient with good and long-standing orthoplasty.

Objective:To investigate the response of mandibular condylar chondroprogenitors to flow fluid shear stress(FFSS).Methods:Chondroprogenitors were in vitro cultured and stimulated with FFSS that can cause cell degeneration,and treated with sec-ond-generation high-throughput RNA sequencing.Differential gene expression was screened using DESeq2 software for gene ontology(GO)functional enrichment analysis,kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis and protein-protein interaction(PPI)network analysis.qRT-PCR was performed to validate the core genes screened by PPI.Results:A total of 1996 differentially expressed genes were obtained,mainly including inflammatory response and cell cycle related molecules.Among them,Actal,Atf3,Ccl2,116,Nfkbia,Ret and Vcaml were identified as the core genes.Conclusion:FFSS stimulation affects chondroprogenitor function by acting on inflammatory responses and cell cycle-related signaling pathways in chondroprogenitors.

OBJECTIVE：To study the improvement eff ects and its mech anism of Guiyuan decoction formula granules （GDFG） on model mice with decreased ovarian reserve （DOR）. METHODS ：Totally 42 female ICR mice whith with normal estrous cycle were randomly divided into control group ，model group ，estradiol valerate group （positive control ，0.15 mg/kg）and GDFG low-dose，medium-dose and high-dose groups （0.75，1.49，2.98 g/kg），with 7 mice in each group. Except for control group ，other groups were given cisplatin （3 mg/kg）intraperitoneally to establish DOR model. After modeling ，administration groups were given relevant medicine intragastrically；model group and control group were given normal saline intragastrically ，once a day ，for consecutive 4 weeks. After last administration ，ELISA assay was used to measure the serum levels of anti-Müllerian hormone （AMH）and follicle-stimulating hormone （FSH）in mice. Histopathological morphology of ovarian was observed by HE staining. Protein distribution of AMH receptor Ⅱ（AMHRⅡ）and Smad 4 in ovarian tissue were observed by immunohistochemistry. Protein expression of AMHR Ⅱ and Smad 4 were detected by Western blot assay. RESULTS ：Compared with control group ，theserum level of AMH ，the expression of AMHR Ⅱ and Smad 4 protein in ovarian tissue in model group were significantly decreased （P＜0.01），while the FSH level in serum was significantly increased （P＜0.01）；follicles were crumpled and lost nucleus ，ovarian interstitial were fibrosis ，luteum were loose ； AMHRⅡ and Smad 4 protein in ovarian tissue were mainly distributed in the follicle membrane and ovarian interstitial. Compared with model group ，the serum level of AMH ，the expression of AMHR Ⅱ and Smad 4 protein in ovarian tissue was increased significantly in GDFG groups （P＜0.01），while the serum level of FSH was decreased significantly （P＜0.05 or P＜0.01）；in ovarian tissue ，follicles at all levels could be found and follicle morphology was improved ，and no obvious nuclear loss and cumulus formation were found ；AMHRⅡ and Smad 4 protein were mainly distributed in the follicular nucleus （except for GDFG high-dose group) and the granular cell membrane （mainly distributed in the sinus follicles of GDFG medium-dose group ）；they were slightly distributed around the mature follicular nucleus or in corpus luteum. CONCLUSIONS ：GDFG can improve ovarian function of DOR model mice. The mechanism may be related with promoting serum level of AMH ，protein expression of AMHR Ⅱ and Smad 4，improving the distribution of AMHR Ⅱ and Smad 4 protein in ovarian granulosa cell membrane and follicular nucleus ， reducing FSH levels.
