Matrix metalloproteinase (MMP)-9 is closely correlated with the pathophysiological processes of cerebral edema,inflammatory reaction and apoptosis after intracerebral hemorrhage.As a specific brain-derived protein,the different levels of S100B may present different physiological and pathological effects.Its concentration can reflect the degree of central nervous system damage.This article reviews the action mechanisms of MMP-9 and S100B in intracerebrai hemorrhage.

In-stent restenosis after interventional treatment remains an unsolved and important clinical problem. The proliferation and migration of arterial smooth muscle cells are key events frequently followed by vascular restenosis after angioplasty and continuous inflammation may also be the other important factor for the restenosis after stenting. Study of the pathogenesis of restenosis may find some potentially novel therapeutic pathways for attenuating in-stent restenosis.

Objective · To explore the clinical application value of hysteroscopic transcervical resection of endometrium (TCRE) combined with levonorgestrel-releasing intrauterine system (Mirena) in the treatment of adenomyosis. Methods · A total of 112 cases of adenomyosis patients were divided randomly into the combination group and Mirena group. The combination group (56 cases) was treated by TCRE endometrium endometrial resection, assisted Mirena treatment after operation. Mirena group (56 cases) was treated by Mirena only. The follow-up lasted 36 months after treatment, including measures of the volumes of menstrual bleeding, hemoglobin levels, dysmenorrhea scores, uterine volume, serum CA125 levels and incidences of complications.Results · The median follow-up duration was 42 months, and the three-year follow-up rate was 73.21% for the combination group and 50% for the Mirena group. After surgery, the volumes of menstrual bleeding of patients in 3-36 months decreased significantly, with an increase in hemoglobin level and a decrease in serum CA215 level and dysmenorrhea scores. Compared with their situations before surgery, the difference was significant (P<0.05). A comparison of uterine volume before and after surgery showed that there is a significant decrease in the uterine volume in both groups in6-12 months after surgery (P<0.05).Twenty-four months after surgery, it shows thatthe combination group has a much more significant decrease in uterine volume [(171.3±34.8) mm3] than Mirena group [(213.7±38.6) mm3] (P<0.05). The hysterectomy rate in Mirena group was significantly higher than that in the combination group (12.50% vs 5.36%); the ring expulsion rate was 16.07% in Mirena group and 5.36% in the combination group, and the break through bleeding happeningrate was 8.93% in Mirena group and 3.57% in the combination group. After 36 months an irregular small amount of vaginal bleeding rate was 62.25% in Mirena group, while it was only 12.50% in the combination group. There was significant differencewhen comparing above indices between two groups (P<0.05). There was no obvious differences in most common side effects of both groups. Conclusion · HysteroscopicTCRE combined with Mirena reduces significantly the irregular menstrual bleeding caused by merely applying Mirena. It has a prominent clinical efficacy and can be an effective approach in treatment of adenomyosis.

Objective To study the effect of eicetaxin combined with psychological intervention on early cognitive function in the patients with hip arthroplasty.Methods From January 2015 to December 2016 in our hospital, 80 cases with hip arthroplasty were selected as the research object, which were divided into two groups (the control group and the observation group) according to intervention methods, 40 cases in each groups.The control group were given dicetaxin, the observation group were received dicetaxin combined with psychological intervention.The clinical data in the two groups were compared.Results After intervention, the cognitive function in the observation group was better than that in the control group;the clinical intervention effect in the observation group (95.0%) was better than that in the control group (72.5%);The incidence of adverse reactions (7.5%) in the observation group is lower than that in the control group (40.0%).The difference of the above data in the two groups was statistically significant(P< 0.05).Conclusion The clinical effect is significant that dezocine combined with psychological intervention were used on patients with hip arthroplasty, which can improve the early cognitive function in the patients, is worthy of clinical application.

OBJECTIVE: To study the feasibility and the generalizability of the Remote fitting models of hearing AIDS from primary hospitals. METHOD: we comparative analyzed the speech recognition scores and satisfaction of 45 cases with traditional hearing AID fitting and with a hearing aid remote test respectively. RESULT: 45 cases were analyzed in each group, including traditional hearing AID fitting model and remote test, and 35 recovered in traditional fitting model group, and the recovery rate was 77.8%; Remote fitting model rehabilitation 42 cases, recovery rate was 93.3%, the difference was statistically significant (P < 0.05). In 6 weekend wear hearing AIDS, traditional fitting model of speech recognition rate increased by 19.40% on average, the average distance fitting model speech recognition rate increases by 27.47%, the average distance fitting model than traditional fitting the speech recognition rate increased significantly more (8.07%). Effect of hearing aid international questionnaire results suggest: 45 cases using traditional model fitting hearing AIDS patients, 33 cases (73.3%) satisfaction, 12 cases (26.7%) patients after use. Remote and 45 cases of using hearing AIDS fitting model, satisfied with 40 cases (88.9%), 5 cases (11.1%) patients after use. CONCLUSION the curative effect and the satisfaction of remote fitting models of hearing AIDS on hearing impairment are better than that in patients with traditional fitting models. Therefore it is more worthy of clinical application especially in basic level hospitals.

Objective:To study the relationship between graduate students'personalities, life events and psychic symptom.Methods:828 graduate students in Tianjin were investigated, their psychosomatic symptoms were rated with SCL-90 and psychosocial factors were assessed with Cattell 16 Personality Factors Questionnaire and Life Event Scale.Result:The first three factors in the psychosomatic symptoms were displayed in order: Obsession-compulsion(0.67?0.55), Interpersonal sensitivity (0.61?0.56), and Depression(0.50?0.51).The personalities were revealed as follows: E (6.23?1.69) , F(6.23?1.80) and Q 4(6.12?1.10), these factors were higher than Chinese norm, L (3.82?1.62), O (4.64?1.70) and I (4.86?1.62) were lower than norm.Conclusion:Male, having siblings, engineer and negative scores of work and study are risk factors for psychosomatic symptoms, whereas medical staff is a protective one.

BACKGROUND: Traditional acoustic examination is to make subjective descriptions of abnormal acoustic features, or carry out quantitative analysis of vowels with sensitive consonant utterance only subjected to qualitative analysis.OBJECTIVE: To make quantitative analysis of the acoustic features of sensitive consonants before and after restoration with complete denture. DESIGN: Randomized controlled experiment.SETTING: Department of Prosthodontics; Department of Oral & Maxillofacial Surgery, Ninth People's Hospital of Shanghai Second Medical University.PARTICIPANTS: Totally 30 edentulous patients who received treatment in the Department of Prosthodontics, Ninth People's Hospital of Shanghai Second Medical University, between November 2001 and March 2003-03were enrolled in this study. They were divided into plastic base group and metal base group with 15 patients in each group according to the denture base; the two groups of patients were matched in baseline data such as sex and age. Inclusion criteria: had no history of denture repairing, aged 45-75years, had received certain years of education, could speak Mandarin with out obvious dialect, had no obvious dysaudia (≤ 20dB), and had not received acoustic therapeutic training.METHODS: Plastic base group: the plastic base was 2.0-2.5 mm thick,with smooth anterior palate polished surface. Metal base group: the metal base was 1.0-1.5 mm thick, covering entire palate and forming palatal rugae, which transformed to net base at alveolar ridge side, and cheek base was plastic. The scope of base, the posterior bank of denture, overbite of anterior teeth, coverage degree, occlusal surface and 1/3 vertical range beneath surface were designed conventionally. Utterance of/zi/ and/ji/ by edentulous patients was detected before restoration, at the beginning and after restoration 1, 2, 4, 8 weeks respectively, with the results analyzed with the assistance of computer acoustic analysis system, the linear forecast technology and fast Fourier transformation were used to record the 1st and 3rdformants, the computer acoustic analytic sampling frequency was 10 000 Hz and he step number of linear forecast technology was 12.MAIN OUTCOME MEASURES: The differences in acoustic parameters between the detected utterances/zi/and/ji/.RESULTS: According to the intention-to-treat analysis, 30 patients were enrolled in this experiment and all of them entered the result analysis. ①When utterance/zi/was detected, most of 1st formants were found gradually reduced in plastic base group and metal base group after restoration compared to that before restoration, most obviously at week 8 [(353.67±35.65),(322.60±44.03); (332.27±37.10), (302.20±40.39); P ＜ 0.05]. However,the 3rd formant variance was different between the two groups, presented by gradually ascending in plastic base group and gradually descending in metal base group. ② When the detected utterance was/ci/, changes of the 1st formants in two groups were basically the same as /zi/; moreover the changes of the 3rd formants also displayed different tendency in the two groups.CONCLUSION: Reducing the basal thickness of complete denture and reconstructing palatal rugae will be helpful for the acoustic functional restoration in patients with dentition defects. The computer acoustic analysis system can be used for quantitative analysis of acoustic features of patients before and after restoration with complete denture.
