Objective To evaluate the effectiveness of using low-frequency repetitive transcranial magnetic stimulation (rTMS) along with donepezil in the rehabilitation of aphasia after cerebral infarction. Methods Fortythree aphasic patients with acute cerebral infarction were assigned into a treatment group or a control group.Both groups received standard basic treatment for acute cerebral infarction.From day 7 on,both groups received oral donepezil hydrochloride (5 mg/d) for 12 consecutive weeks.The treatment group received in addition 2 sessions of low frequency rTMS on the language center of the right hemisphere.The first session started at day 7 after onset,and each session consisted of rTMS on 10 consecutive days (once per day).There was a resting interval of 3 d between the two sessions.The rehabilitation of the aphasia was assessed prior to and after each session,and at the end of the entire 12 weeks of treatment using the western aphasia battery ( WAB ) scoring system and the aphasia quotient (AQ). Results There was no significant difference between the two groups after the first session in terms of the WAB or AQ results.However,the difference in improvement became statistically significant after the second session,as well as at the end of the entire 12 weeks.The average change in AQ was significantly greater in the treatment group. Conclusion Donepezil combined with rTMS early in the acute phase of cerebral infarction is helpful for the rehabilitation of aphasia.

BACKGROUND:The umbilical cord mesenchymal stem cells possess multipotent differentiation capacity, but less research focus on its differentiation into fibroblasts.
OBJECTIVE:To investigate the capacity of human umbilical cord mesenchymal stem cells differentiating into fibroblasts.
METHODS:Using adherent method, human umbilical cord mesenchymal stem cells were isolated, and flow cytometric analysis of the surface antigen was performed. Passage 3 cells were selected for osteogenic and
adipogenic differentiation, and cells differentiated into fibroblasts under the induction of basic fibroblast growth factor. RESULTS AND CONCLUSION:Adherent stem cells were stably isolated from the umbilical cord. Human umbilical cord mesenchymal stem cells lowly expressed CD31, CD45, CD40, HLA-DR, but strongly expressed CD29, CD90, CD44, CD105. Oil red O staining showed red droplets were ful of the cytoplasm after adipogenic induction;alizarin red staining showed red calcium nodules after osteogenic induction. After induced by basic fibroblast growth factor, the type I col agen expression was significantly higher than that in the control group. These findings indicate that the adherent human umbilical cord mesenchymal stem cells are reliably isolated with high purity;basic fibroblast growth factor can induce differentiation of umbilical cord mesenchymal stem cells into fibroblasts.

Freshwater crabs and snails were collected from Ninghai County in Zhejiang Province, and examined respectively for Paragonimus metacercariae and cercariae. Among 97 freshwater crabs found, the prevalence was 11.3% (11/97) with a mean intensity of 1 metacercariae per crab. It was 10.2% (5/49) and 20.2% (4/20) in the groups weighted 5-15 g and 15-25 g respectively, with an average intensity of 1, and no metacercariae were found in weight group of 25-35 g. Two positive crabs were found from 20 crabs with a low weight (

A 36-year old woman was admitted for menolipsis for 71 days and vaginal bleeding for 38 days and aggravation of vaginal bleeding with abdominal distension for 10 days. Gynecological examination revealed marked hysterauxesis without tenderness with a high HCG level. CT examination led to the misdiagnosis of trophoblastic tumor with lymph node metastasis of the left iliac vessels. The patient underwent subsequent laparotomy, and a huge pelvic hematoma with maximum diameter of 20 cm was found, for which left salpingectomy was performed. Pathologic examination of the surgical specimen supported the diagnosis of old tubal pregnancy. This case represents a rare clinical entity of old ectopic pregnancy manifested as a painless huge pelvic mass that can be easily misdiagnosed based on radiographical findings only.

OBJECTIVES: Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare female genital tract malformation, and there are few large sample studies reported at home and abroad. The clinical manifestations of this syndrome are diverse, and insufficient understanding may delay the diagnosis and treatment of the patients. This study aims to analyze the clinical characteristics of different types of HWWS patients, and to improve the diagnosis and treatment of HWWS. METHODS: The clinical data of patients with HWWS who were hospitalized in the Department of Obstetrics and Gynecology, Third Xiangya Hospital of Central South University from October 1, 2009 to April 5, 2022 were retrospectively analyzed. The age, medical history, physical examination, imaging examination and treatment of the patients were collected for statistical analysis. The patients were divided into an imperforate oblique vaginal septum type, a perforate oblique vaginal septum type, and an imperforate oblique vaginal septum and cervical fistula type. The clinical characteristics of different types of HWWS patients were compared. RESULTS: A total of 102 HWWS patients were enrolled, with age of 10-46 years old, including 37 (36.27%) patients with type I, 50 (49.02%) type II, and 15 (14.71%) type III. All patients were diagnosed after menarche, with an average age of (20.5±7.4) years. There were significant differences in the age of diagnosis and course of disease among the 3 types of HWWS patients (both P<0.05). Patients with type I had the youngest age of diagnosis [(18.0±6.0) years] and the shortest course of disease (median course of 6 months), while patients with type III had the oldest age of diagnosis [(22.9±9.8) years] and the longest course of disease (median course of 48 months). The main clinical manifestation of type I was dysmenorrhea, and the main clinical manifestation of type II and type III was abnormal vaginal bleeding. Of the 102 patients, 67 (65.69%) patients had double uterus, 33 (32.35%) had septate uterus, and 2 (1.96%) had bicornuate uterus. The vast majority of patients had renal agenesis on the oblique septum, and only 1 patient had renal dysplasia on the oblique septum. The oblique septum located on the left side in 45 (44.12%) patients and on the right side in 57 (55.88%) patients. There were no significant differences in uterine morphology, urinary system malformation, pelvic mass, and oblique septum among the 3 types of HWWS patients (all P>0.05). Six (5.88%) patients had ovarian chocolate cyst, 4 (3.92%) patients had pelvic abscess, and 5 (4.90%) patients had hydrosalpinx. All patients underwent vaginal oblique septum resection. Among them, 42 patients underwent hysteroscopic incision of the oblique vaginal septum without destroying the intact hymen because they had no sexual life history, and the remaining 60 patients underwent traditional oblique vaginal septum resection. Among the 102 patients, 89 patients were followed up for 1 month to 12 years. The symptoms of vaginal oblique septum in 89 patients such as dysmenorrhea, abnormal vaginal bleeding and vaginal discharge were improved after operation. Among the 42 patients who underwent hysteroscopic incision of the oblique vaginal septum without destroying the intact hymen, 25 patients underwent hysteroscopies again 3 months after operation, and there was no obvious scar formation at the oblique septum incision site. CONCLUSIONS Different types of HWWS have different clinical manifestations, but all can be manifested as dysmenorrhea. The patient's uterine morphology can be manifested as double uterus, septate uterus, or bicornuate uterus. The possibility of HWWS should be considered if uterine malformation is combined with renal agenesis. Vaginal oblique septum resection is an effective treatment.
