Objective To evaluate the follow-up results of patients with cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)after surgical treatment.Methods A retrospective analysis of consecutive patients with CIN Ⅲ after surgical treatment between Jan 1st,1999 and Jun 30 th,2004 was performed.The follow- ups of the patients after surgical treatment were assessed.Results In the follow-up of patients with CINⅢ after surgical treatment,the rate of abnormal cytology was 9.3%.The rate of follow-up was higher in patients with cervical conization than in patients with initial hysterectomy and in patients of the oncological group than of the non-oncological group.The rate of follow-up was lower in patients over 40 years old.There was no difference in the residential areas of the patients.Conclusions Cytological follow-up of patients with CINⅢ after operation is varied.The rate of follow-up is lower in patients over 40 years old,in patients having initial hysterectomy and in patients of the non-oncological group.The rate of follow-up is associated with the knowledge about CIN of both surgeons and patients.

Objective To quantify the normal range of the ultrasonically measured thickness of the masseter which is related to the variation of the facial morphology in different young individuals. Methods The masseter thickness of 50 young healthy adults (25 men and 25 women) was measured bilaterally under relaxed conditions and with maximal clenching by a real-time ultrasound imaging technique. The relation between masseter thickness and facial morphology was also observed. Results Under relaxed conditions, the mean thickness of the muscle in men was (11.83±1.19)mm, and under contracted conditions, (15.51 ±1.40)mm. In women, the respective measurements were(9. 84 ± 1. 03)mm and(13.02 ± 1.10)mm. In men thethickness of masseter had a negative linear correlation to the indices of FH/FWa (the ratio of the anteriorfacial height to the intergonial width) and FWz/FWa (the ratio of the bizygomatic facial width to the intergonial width). Conclusions The mean thickness of the masseter in men was larger than that in women,and the thickness of the mascle was related to the male facial morphology.

OBJECTIVETo investigate the expression of Caspase-3 and Hsp70 in rabbits after severe traumatic brain injury (TBI) and to explore the feasibility of its application in estimation of injury time in forensic medicine.

METHODSA rabbit model of heavy TBI was developed by high velocity impact on the parietal bone with an iron stick. Totally 8 healthy adult New Zealand white rabbits were randomly divided into control group (n equal to 2) and injury group (n equal to 6). Four hours after injury, tissue specimens from the parietal lobe, temporal lobe, occipital lobe, cerebellum and brainstem were harvested to detect the expression of Hsp70 and Caspase-3 by immunohistochemistry. Besides, the gray values of cells positive for Hsp70 and Caspase-3 were analyzed with an image analyzer.

RESULTSImmunohistochemistry staining demonstrated a low level of Caspase-3 and Hsp70 expression in normal control group. While in injury group, both the Caspase-3 and Hsp70 expression was significantly elevated (P less than 0.05). Positive cells gathered around the lesion focus. Occipital lobe and cerebellum had fewer positive cells while temporal and brainstem had the fewest.

CONCLUSIONThe expression of Caspase-3 and Hsp70 at an early stage following severe TBI is characteristic and can be applied to estimate the time of injury.

Objective To explore the influence of Yoga on the perimenopausal disturbance of middleaged women so as to provide reference for carrying out health promotion programs in community.Methods Totals of 80 middle-aged women of the community in the Lusong of Zhuzhou were divided into Yoga group (n =40) and control group (n =40).The Yoga group received the exercise of Yoga at least sixteen weeks,while the control group kept their life style.And they were investigated with the perimenopausal disturbance symptoms,and physiological indexes such as blood pressure,waist line,body weight,body mass index,muscle tone,balance function were measured after 16 weeks of Yoga exercise.Results After sixteen weeks,except genital system,there were significant differences in total perimenopausal disturbance symptoms score [(49.00 ± 9.290) vs (70.50 ± 17.304) ;t =-4.896,P =0.014] and sympathetic autonomic nerve system and orthopedic system and urinary system and psycholopy spiritual symptom between Yoga group and control group (t =-2.706,-2.013,-2.535,-7.610,respectively; P ＜ 0.05).And the differences of physiologic indexes such as blood pressure,waistline,body weight,body massindex,muscle tone,balance function between Yoga group and control group were statistically significant (P ＜ 0.05).Conclusions Yoga exercise can improve the status of perimenopausal disturbance symptoms of perimenopausal women,and promote their quality of life.

Objective To analyze the effect of probiotics combined with early enteral nutrition on infection and gastrointestinal dysfunction in patients undergoing mechanical ventilation in intensive care unit (ICU).Methods Prospective cohort study was adopted to select patients who admitted to ICU in a hospital from February 2016 to October 2017, they were randomly divided into three groups:A, B, and C.Group A received early enteral nutrition combined with probiotics, group B received early enteral nutrition, and group C received early parenteral nutrition.Infection condition, level of infection indicators (on the 3 rd, 7 th and 14 th day after treatment), occurrence of gastrointestinal dysfunction, acute physiology and chronic health evaluation II (APACHE II) on the 14 th day after treatment were compared among three groups.Results Incidences of infection in group A, B, and C were 6.00％, 20.00％, and 22.00％ respectively, difference among three groups was significant (χ2=8.57, P=0.01).C-reactive protein (CRP) and white blood cell count (WBC) in group A on the 7 th and 14 th day were both lower than those in group B and C;procalcitonin (PCT) in group A and B on the 3 rd day were both lower than that in group C;PCT in group A on the 7 th and 14 th day were both lower than those in group B and C;difference were all statistically significant (all P＜ 0.05).Incidence of abdominal distension (8.00％), diarrhea (4.00％) and gastric retention (4.00％) in group A were the lowest among three groups.APACHE II score in group A on the 14 th day after treatment was lowest.Conclusion Early enteral nutrition combined with probiotics for treatment of ICU patients with mechanical ventilation can effectively reduce the incidence of infection and gastrointestinal dysfunction, promote rehabilitation, which is worth promoting the application.

OBJECTIVETo determine if multi-detector CT (MDCT) characterization of plaque is correlated with the classification of acute coronary syndrome (ACS).

METHODSAltogether 1900 patients were examined by MDCT from December 2007 to May 2009, of whom 95 patients fulfilled the criteria of ACS. Those patients were divided into the discrete plaque group ( n=61) and diffuse plaque group ( n=34) based on the findings in MDCT. The clinical diagnosis of ACS and CT results were analyzed, including segment stenosis score, segment involvement score, 3-vessel plaque score, left main score, calcification score, and remodeling index. The incidences of major adverse cardiac events in follow-up period were also recorded.

RESULTSThe patients of the diffuse plaque group were older than those of the discrete plaque group ( Pü0.0001). The diffuse plaque group presented more cases of hypertension, peripheral artery disease, diabetes, and heart failure than discrete plaque group (all P<0.05). All the 5 patients with ST-segment elevation myocardial infarction were found in discrete plaque group. The segment stenosis score of the discrete plaque group was lower than that of the diffuse plaque group(5.15±3.55 vs. 14.91±5.37, Pü0.001). The other four scores demonstrated significant inter-group difference as well (all P<0.05). The remodeling index of thediscrete plaque group was higher (1.12±0.16 vs.0.97±0.20, Pü0.05). Follow-up data showed that major adverse cardiac events occurred more frequently in diffuse plaque group than in discrete group (29.41% vs. 11.48%, P=0.0288).

CONCLUSIONSCharacteristics of discrete and diffuse plaques may be significantly different among different classes of ACS. The diffuse plaque may present higher risk, correlated to higher mortality. The diagnosis of discrete and diffuse plaques by MDCT would provide a new insight into the prognosis and treatment of ACS.

OBJECTIVETo assess the feasibility and accuracy of CT coronary angiography (CTCA) combined with adenosine stress myocardial perfusion scintigraphy (MPS) for diagnosis of flow-limiting coronary stenosis.

METHODSA total of 105 patients with suspected or established coronary artery disease (CAD) underwent CTCA and MPS within 4 weeks before invasive coronary angiography. The accuracy of CTCA/MPS in the diagnosis of flow-limiting coronary stenosis was evaluated in comparison with the results of quantitative coronary angiography and MPS.

RESULTSThe sensitivity, specificity, positive predictive value and negative predictive value of CTCA/MPS as a combined approach for detection of flow-limiting coronary stenosis were all 100%. In 16% (9/55) of the patients, revascularization procedures were performed and no flow-limiting stenosis was found.

CONCLUSIONCombination of CTCA and MPS has an excellent accuracy for detecting flow-limiting coronary stenosis as compared with quantitative coronary angiography/MPI, and can be a useful gatekeeper for revascularization procedures.

In this paper, we studied the relationship between the prostaglandin F(2alpha) (PGF(2alpha))-induced cardiac hypertrophy and calcineurin (CaN) signal transduction pathway in vivo and in vitro. Male Sprague-Dawley rats were given a single i.p. injection with monocrotaline (MCT) (60 mg/kg) and then given orally with celecoxib (20 mg/kg) or vehicle once a day for 14 d before (from d 1 to d 14) or after (from d 15 to d 28) right ventricular hypertrophy (RVH) was formed. Body weight (BW), right ventricular weight (RV), left ventricular with septum weight (LV), as well as lung weight were determined. RVH index (RVHI=RV/LV), RV/BW, and lung weight/BW were calculated and histological changes were observed with transmission electron microscope. PGF(2alpha) level, atrial natriuretic peptide (ANP) and CaN mRNA expressions, expression of CaN and its downstream effectors, NFAT(3) and GATA(4) protein were assayed by EIA kit, RT-PCR, and Western blotting, respectively. The cardiomyocyte hypertrophy in primary culture induced by PGF(2alpha) (0.1 micromol/L) was evaluated by measuring the cell diameter, protein content, and ANP mRNA as well as CaN mRNA expressions. It was found that 14 d or 28 d after MCT was given, the RVHI, RV/BW, and lung weight/BW were significantly increased by 47%, 53% and 118%, and by 64%, 94% and 156%, respectively; at the same time PGF(2alpha) levels in RV tissue were increased by 44% and by 51% with increasing RVHI, and elevated expressions of ANP and CaN mRNA, as well as CaN, NFAT(3) and GATA(4) proteins in a positive correlation manner. Furthermore, some histological injuries were found in RV tissue. Celecoxib, a cyclooxygenase inhibitor, obviously blunted the elevation of RVHI, RV/BW, and lung weight/BW no matter it was given before or after RVH. In vitro experiments showed that 0.1 micromol/L PGF(2alpha) significantly increased the cardiomyocyte diameter and protein content, and promoted ANP and CaN mRNA expressions, which was blocked by cyclosporin A, a CaN inhibitor. Our results indicate that PGF(2alpha) may be involved in cardiac hypertrophy induced by MCT in rats through CaN signal transduction pathway.
