Objective To investigate in vitro activity of antimicrobial agents against Enterococcus spp . isolated from clinic specimens in a hospital.Methods 188 Enterococcus spp . isolates from specimens sent by clinic depart-ments in June 2013-July 2014 were identified and performed antimicrobial susceptibility testing.Results Of 188 En-terococcus spp . isolates,119 were Enterococcus faecium (E.faecium),60 were E.faecalis ,and 9 were E.avium, these strains were mainly isolated from urine (34.57%)and blood specimens (19.15% ).No daptomycin and linezolid-resistant strain was detected;resistant rates of E.faecium to vancomycin was 1 .68%,to penicillin, ampicillin,high concentration gentamycin,erythromycin,and levofloxacin were all > 70%;except tetracycline, resistant rates of E.faecalis to the other antimicrobial agents were all lower than E.faecium,resistant rates of E. faecalis to penicillin and ampicillin were 16.67% and 13.33% respectively.Conclusion Daptomycin has high activity against Enterococcus spp . in this hospital.

Objective To explore the relationship between different types of female reproductive system dysplasia and age of visit, clinical manifestations, common types of combined malformations and endometriosis. Methods The patient′s medical records in the Second Hospital of Hebei Medical University from December 2002 to June 2016 were collected and retrospectively analyzed. Results Among 924 cases of genital tract dysplasia, uterine dysplasia (65.3%, 824/1 261) was the most common, followed by vaginal dysplasia (28.3%, 357/1 261), hymen atresia and urogenital fistula (3.7%, 47/1 261), and cervical dysplasia (2.6%, 33/1 261). (1) The youngest age was in patients with hymen atresia and urogenital fistula, with a median of 14.5 years old, while the older age were in patients with uterine, vaginal and cervical dysplasia, with median age of 25.0, 24.0 and 23.0 years old, respectively. (2) The clinical manifestations were lack of specificity, mainly abnormal findings of physical examination or accessory examination, primary amenorrhea, lower abdominal pain, infertility, adverse pregnancy history. (3) About other systemic malformations, urological malformations were the most common (4.8%, 44/924), followed by spinal malformations (0.5%, 5/924), inguinal hernia (0.4%, 4/924), heart malformations (0.2%, 2/924), cleft lip and palate (0.2%, 2/924). Oblique vaginal septal syndrome and MRKH syndrome were the most likely to be associated with other system malformations. (4) About combination with endometriosis, there was no significant difference between obstructive genital tract malformations (2.3%, 9/385) and non obstructive genital tract malformations (1.7%, 9/539; P=0.469). Conclusions Female reproductive system dysplasia is the most common in uterine dysplasia, followed by vaginal dysplasia, hymen atresia and urogenital fistula, and cervical dysplasia. The age of visit is generally older, often found by abnormal findings of physical examination or accessory examination, primary amenorrhea, lower abdominal pain, infertility, adverse pregnancy history;and could be combined with a variety of other system malformations, most seen by urinary system malformations,there is also the risk of endometriosis.

BACKGROUND:
Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a severe congenital disorder characterized by vaginal hypoplasia caused by dysplasia of the Müllerian duct. Patients with MRKH syndrome often require nonsurgical or surgical treatment to achieve satisfactory vaginal length and sexual outcomes. The extracellular matrix has been successfully used for vaginal reconstruction.
METHODS:
In this study, we developed a new biological material derived from porcine vagina (acellular vaginal matrix, AVM) to reconstruct the vagina in Bama miniature pigs. The histological characteristics and efficacy of acellularization of AVM were evaluated, and AVM was subsequently transplanted into Bama miniature pigs to reconstruct the vaginas.
RESULTS:
Macroscopic analysis showed that the neovaginas functioned well in all Bama miniature pigs with AVM implants. Histological analysis and electrophysiological evidence indicated that morphological and functional recovery was restored in normal vaginal tissues. Scanning electron microscopy showed that the neovaginas had mucosal folds characteristics of normal vagina. No significant differences were observed in the expression of CK14, HSP47, and a-actin between the neovaginas and normal vaginal tissues. However, the expression of estrogen receptor (ER) was significantly lower in the neovaginas than in normal vaginal tissues. In addition, AVM promoted the expression of b-catenin, c-Myc, and cyclin D1. These results suggest that AVM might promotes vaginal regeneration by activating the b-catenin/cMyc/cyclin D1 pathway.
CONCLUSION
This study reveals that porcine-derived AVM has potential application for vaginal regeneration.

OBJECTIVE:To shar e the experienc e of pharmaceutical care in Wuhan Jinyintan Hospital (herein after refers to “our hospital ”)under the condition of novel coronavirus pneumonia (COVID-19)epidemic,and to provide reference for other hospitals to deal with public health emergencies. METHODS :The situation of pharmaceutical care in our hospital under the condition of COVID- 19 epidemic was summarized and shared ,including the epidemic prevention and control management (regional division ,disinfection management ,pharmacy personnel training ),supply of drugs and disinfection products ,the monitoring and education of rational drug use by information technology. RESULTS :The pharmacy department of our hospital divided the activity scope into clean area ,potential pollution risk area ,semi pollution area ,and implement different disinfection management. All pharmacists received training ,involving personal health protection ,prevention and control knowledge of COVID-19,health status monitoring ,etc. For supply and guarantee of drugs and disinfectants ,the epidemic drug list of our hospital was formulated ,drugs and disinfectants were purchased accurately and stored in a standardized way. 24 h response telephone was set up in the clinical pharmacy room to receive consultation from clinicians on drug use at any time. The drugs mentioned in the COVID- 19 diagnosis scheme were compared in terms of the mechanism of action and the medication of special populations to form a tablet ,so as to help clinical rational choice treatment drug. CONCLUSIONS :The pharmaceutical care in the designated hospital of COVID- 19 is a professional and complicated work ,involving a wide range of aspects. Pharmacy department must respond actively and adjust the strategy in time so as to play an important role in improving the ability of medical treatment.
