Objective To evaluate the uniformity of different diagnosis criteria of metabolic syn-drome in patients with type 2 diabetes, especially the criteria that suit for metabolic syndrome in type 2 dia-betes patients.Methods The patients with type 2 diabetes, aged from 20~74 years, who were treated at Department of Endocrinology , the Third Affiliated Hospital , Qiqihar Medical University from January 2008 to November 2009 were enrolled.Four hundred and twenty one patients with integral data were analyzed . Waistline, hip line, height, body mass, blood pressure and so on were surveyed , and according to waistline and hip line the waist-to-hip ratio was calculated .On the basis of body mase/height body mass index ( kg/m2 ) was calculated .The blood sugar was detected with the hexokinase method .The blood cholesterol , tria-cylglycerol , the high density lipoprotein cholesterol were determined with the biochemistry method .Urinates the micro albumin level was determined with chemistry to try the belt technology .Diagnosis standards of WHO (1999), NCEP-ATPⅢ(2001),ACCE(2003),EGIR(1999),the Chinese CDS(2007) suggestion metabolism synthesis drafts , the triacylglycerol-waistline standard of Blackburn P forecast cardiovascular e-vent(2003) were applied to calculate prevalence rate of metabolism synthesis .Results The 421 enrolled testees were involved in the result analysis .⑴Prevalence rates of type 2diabetes and metabolism synthesis in various single component: In the investigation population the differences in body of obesity , hypertension and hypertriacylglycerolemia , the low and high density lipoprotein cholesterol blood sickness between the men and women were insignificant , but the overload (66.1%) in males was remarkably higher than that in females (49.7%).The prevalence rate in abdomen obese in males (74.0%) was remarkably higher than that in females(59.9%).⑵Abnormal distribution of metabolism in patients with type 2 diabetes: Preva-lence rate of one kind of abnormal metabolism was 27.2%.Prevalence rate of two kinds of or above two kinds of above abnormal metabolism was 61.0%.Prevalence rate of three kinds of above abnormal metabo-lism was 26.1%,and the prevalence rate in females was not higher than that of males ( P >0.05 ) .⑶After age and sex lamination ,prevalence rates of metabolism synthesis and it's the correlated disease:The preva-lence rates of the high hypertriacylglycerolemia , hypertension , metabolism synthesis had the tendency of in-creasing along with the age .Prevalence rates of abdominal obesity and the low and high density lipoprotein cholesterol blood sickness had the increased tendency in females , but it was not obvious in males .Except that 35~44 years old of age group prevalence rate of the high hypertriacylglycerolemia in males ( 62.1%) was remarkably higher than that in females ( 29.2%) ( P <0.005 ) , and the 20~35 years old age group prevalence rates of metabolism synthesis in males (41.2%)were remarkably higher than outside the females (20.0%)( P <0.05).In other various age groups ,there was insignificant difference in prevalence rate between males and females .⑷The prevalence rate of WHO diagnosis standard for metabolism synthesis (62.9%) had good concordance with the prevalence rate of the Chinese CDS diagnosis standard for metabo -lism-synthesis ( 66.7%) .The prevalence rate of ACCE diagnosis standard for metabolism synthesis (88.8%) had good concordance with the prevalence rate of the EGIR diagnosis standard for metabolism synthesis (86.6%).The prevalence rate of Blackburn P forecast cardiovascular event (20.9%),which was distanced from the result of the diagnosis standards ( P <0.005 ) .Conclusion ⑴Patients with type 2 di-abetes have high metabolism syndrome proportion rate , and the abnormal metabolism proportion rate in sin-gle group is also higher.⑵WHO (1999) metabolism syndrome diagnosis standard and CDS (2007)sugges-tion standard are suitable for Chinese metabolism -synthesis in type 2 diabetic patients .⑶The metabolism syndrome diagnostic standards of EGIR and ACCE are similar in proportion rate in Chinese patients with type 2 diabetes , which is accorded with the findings of former literatures .Whether that can be used widely deserves further study .⑷The diagnostic criteria of triacylglycerol waistline is not suitable for Chinese type 2diabetic patients.

Objective To develop an in vitro model for cranial suture of neonatal SD rat. Methods The parietal hones with the sagittal suture were removed from SD rats (19-days old) for organ culture. In the experimental group, tensile force 3.92×10~(-3) N (0.4 g) was applied by helical springs, whereas no tension (0 N) was set in control group. These explants were observed under inverted microscope. At the end of the incubation period for 24 hours, general conditions were observed under inverted microscope and histological conditions were observed after hematoxylin and eosin stain. Results Under inverted micro-scope, sutures had no obvious changes in control group, whereas sutures were enlarged gradually in the experimental group. With histological observation, sutures developed normally in control group, but in experimental group, osteohlasts and capillary vessels proliferated actively in the suture. Conclusions In vitro model of cranial suture can be cultured and grown successively.

Objective To observe the analgesic effects of dexmedetomidine combined with dif-ferent-doses of sufentanil in patients undergoing spine surgery.Methods Sixty patients(ASA grade Ⅰor Ⅱ degree,age 18-70 years)undergoing spine surgery were randomly assigned into three groups ac-cording to PCA formulation(n =20):3 μg/kg sufentanil group (group S1),1.5 μg/kg dexmedetomi-dine+ 2 μg/kg sufentanil group (group S2 )and 1.5 μg/kg dexmedetomidine + 1 μg/kg sufentanil group (group S3).The same anesthesia method was applied among three groups.Patient-controlled intravenous analgesia pump was applied before 30 minutes prior to the end of surgery.The drugs in each group were diluted to 1 50 ml and infused by a pump at a rate of 3 ml/h with a patient-controlled analgesia (PCA)bolus of 0.5 ml and lock time of 30 minutes.VAS and Ramsay scores at 2 h(T0 ),4 h (T1 ),8 h(T2 ),12 h(T3 ),24 h(T4 )and 48 h(T5 )after surgery were estimated.Postoperative nausea and vomiting,bradyrhythmia and hypersomnia were also recorded.Results Compared with group S1, VAS of groups S2 and S3 was significantly decreased at T1-T5 (P <0.05).There were also no signifi-cant difference in the incidence of postoperative nausea and vomiting,bradyrhythmia and hypersomnia among three groups.Conclusion Dexmedetomidine of 1.5 μg/kg can significantly reduce the dosage of sufentanil on postoperative analgesia in patients undergoing spine surgery,and decrease the rate of postoperative nausea and vomiting without any bradyrhythmia and hypersomnia.

Objective To analyze the clinical features of 35 patients with Silver-Russell syndrome (SRS) in Beijing Children's Hospital in recent 6 years,and to recognize the clinical manifestations and improve the diagnosis of the disease.Methods The diagnostic criteria of SRS were studied retrospectively,the differences among 3 different diagnostic criteria were compared.Results Thirty-five SRS patients were diagnosed by means of 3 criteria,over a period from 2006 to 2012.There were 23 males and 12 females,with age range 0.08 ～ 12.15 yr.77 ％ of cases met the three criteria,97％ met two of the three criteria.There were dwarfism in 33 cases (94.2％),genital abnormalities in 1 case (2.9％),and asymmetry of limbs in 1 case (2.9％).The clinical characteristics with the frequencies accounting for over 80％ included short stature (average height-3.61 SDS),leanness (body mass index ＜-2.11SDS),bone dysmorphism including triangular face,irregular teeth,asymmetry of limbs,clinodactyly of fifth finger,and bone age obviously lagged behind.60％ of the cases showed bone age lagging behind more than 1 year.Height lagging behind was more obviously then bone age.Conclusions The diagnosis of SRS is mainly based on Clinical manifestation,laboratory and biochemical examinations are of no avail.There is a high coincidence with the 3 different diagnostic criteria.Clinical features in more than 80％ patients with SRS are short stature,craniofacial triangular dysmorphism,irregular teeth,limbs asymmetry and fifth finger clinodactyly,and mild lagging behind of bone age.

Objective To explore the diagnostic value of three-dimensional ultrasound parameters-vascularity index (VI) and the volume of kidney in chronic kidney disease (CKD). Methods A total of 80 CKD patients at different stages and 30 healthy adults were enrolled in the study. VI and the renal volume were calculated with three-dimensional ultrasound, while resistance index (RI), cortical thickness (CT) and the volume of kidney were calculated with two-dimensional ultrasound, and the correlation of those parameters were analyzed statistically. Results VI of CKD2 patients reduced significantly compared with the control group, and RI of CKD3 patients increased significantly, CT of CKD3 patients reduced significantly. The diagnostic sensitivity, specificity and diagnostic value of VI in patients with early and late CKD were all higher than thpse of RI. Compared with the control group, three-dimensional ultrasound of renal volume and two-dimensional ultrasound volume of CKD 1 patients increased significantly, three-dimensional ultrasound volume of CKD2 patients reduced significantly, and two-dimensional ultrasound volume of CKD4 patients reduced significantly. There was significant negative correlation among VI, three-dimensional ultrasound volume, CT, two-dimensional ultrasound volume and pathological change scoring (r=-0.67, -0.52, -0.43, -0.52). Conclusion VI and three-dimensional ultrasound volume can detect renal function damage more earlier and sensitively than RI and two-dimensional ultrasound volume.

Objective To investigate the possibility that procalcitonin (PCT) can predict the outcome of ventilator weaning in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods The AECOPD patients caused by bacteria who received mechanical ventilation in intensive care unit (ICU)of the General Hospital of China National Petroleum Corporation in Jilin from January 2010 to March 2014 were retrospectively selected,and their venous blood PCT levels were monitored daily. When they had passed the spontaneous breathing trial(SBT),their breathing machine and trachea cannula were removed. Afterwards they were closely observed for 48 hours and divided into two groups:success and failure groups according to the outcome of the first weaning,and then the analysis of the PCT difference between the two groups was made. Results In the 52 patients enrolled,there were 38 patients in the success group and 14 patients in the failure group. The baseline information as age,sex,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score between the two groups showed no significant difference(all P>0.05). There was no statistical significant difference in PCT level(μg/L) between success and failure groups when they were admitted(5.33±1.35 and 5.37±1.34,respectively). When they were weaning,the PCT levels of both groups had reduced to some extent(1.37±0.39 and 1.74±0.42,respectively), and the success group was lower than that in the failure group(t=2.971,P=0.005). Conclusion PCT level can be used as a predictive index to guide the time for ventilator weaning in patients with AECOPD.

BACKGROUND: Basic fibroblast growth factor (bFGF) has significant promotion effects on repair in trauma, but local application cannot play a role for a long time.OBJECTIVE: To observe expression of bFGF gene in rabbit bone marrow mesenchymai stem cells (BMSCs) following transfection.DESIGN, TIME AND SETTING: The cytogene in vitro observation was performed at the College of Life Science, Yunnan University from March to August 2009.MATERIALS: One Japan flap-eared rabbit was purchased from the Department of Animal, Kunming Medical College. pCDNA3.1plasmid (Invitrogen, USA) was used in this study.METHODS: Bone marrow was extracted from rabbit anterior superior iliac spine. BMSCs were harvested by the adherent method.Cells were digested and subcultured when 80% confluent. According to GeneBank bFGF cDNA sequence, gene was designed and synthesized. Following electropherosis, the gel was retrieved using xhol I, BamH I enzyme digestion. Restriction enzyme was used to perform enzyme digestion, electropherosis and gene recovery in PcDNA Vector plasmid. bFGF DNA was connected with PcDNA Vector plasmid. PcDNA-bFGF eukaryotic expression vector was constructed. Recombinant was transfected into rabbit BMSCs using liposome infection protocol, and stable transfected line was screened.MAIN OUTCOME MEASURES: BMSC surface antigen expression was measured. Western blot was utilized to determine the expression of target protein.RESULTS: Results of flow cytometry showed that cultured cells were positive for CD90 and CD44, but negative for CD45.Results of immunohistochemistry demonstrated that vessel-derived BMSCs were negative for CD34, but positive for CD44. In cell disruption liquid of bFGF-transfected BMSCs, a significant positive zone of hybridization was visible at M, 23 000. However, no positive band was found in protein from pCDNA3.1(-) blank vector-transfected BMSCs.CONCLUSION: The bFGF gene was successfully transfected into BMSCs, and this target gene can stably express.

Objective To investigate the effect of posterior operation for thoracolumbar burst fractures combined with dislocation. Methods The study involved 22 patients with thoracolumbar burst fractures combined with dislocation admitted into our hospital from October 2005 to March 2008. There were 17 males and 5 females at age range of 18-56 years. The fractures were located at T12-L2. The fractured vertebrae lost its height by 1/4 to 3/4 of the normal height. The upper vertebral dislocation ex-tent was from 25% to 50%. All operations were accomplished within two weeks after injury. The patients were randomly divided into two groups, ie, Group Ⅰ (implanted with 4 pedicle screws in upper and lower vertebrae adjacent to the fractured vertebrae) and Group Ⅱ (implanted with 6 pedicle screws in 2 upper and 1 lower vertebrae adjacent to the fractured vertebrae). The operation time, volume of blood loss, ky-photic angle, neurological function and Low Back Outcome Score (LBOS) were compared between two groups. Results All patients were followed up for 12-36 months. The duration of operation in Group Ⅱ was longer than Group Ⅰ (P < 0.05), with no increase of intraoperative blood loss. Group ⅡI was su-perior to Group Ⅰ in aspects of correction rate, correction loss and implant failure rate (P < 0.05). There was no statistical difference in aspects of neurological function recovery and low back outcome score be-tween two groups. Conclusion Fixation with three vertebrae and six pedicle screws through posterior approach is an effective, feasible and safe procedure for treatment of thoracolumbar burst fractures com-bined with dislocation.

Objective To investigate the risk and value of the dissection of bursectomy in T2 gastric cancer. Methods A total of 86 T2 gastric cancer patients were divided into dissection of bursectomy group (46 cases) and non-dissection of bursectomy group (40 cases) according to the random number table method. The age, Borrman type, tumor location, degree of differentiation, vascular tumor thrombus, operation type, lymph nodes metastasis, number of dissected lymph nodes, tumor size, blood loss during operation, operation time and postoperative complications were observed. The patients were followed up for 1 year, and the local recurrence, metastasis and survive were compared between 2 groups. Results There were no statistical differences in age, Borrman type, tumor location, degree of differentiation, vascular tumor thrombus, operation type, lymph nodes metastasis, number of dissected lymph nodes, tumor size, blood loss during operation and postoperative complications (P>0.05). No metastasis was found in anterior layer of transverse colon and pancreatic capsule in 2 groups. The operation time in dissection of bursectomy group was significantly longer than that in non- dissection of bursectomy group: (169.13 ± 37.94) min vs. (147.45 ± 30.27) min, and there was statistical difference (P<0.05). The patients were followed up for 1 year, and there was no local recurrence in 2 groups. There was 1 case with liver metastasis in dissection of bursectomy group, and 1 case with bony metastasis in non- dissection of bursectomy group. There was no death in 2 groups. Conclusions The dissection of bursectomy in T2 gastric cancer could be abandoned, in order to reduce the operation time, blood loss during operation, and postoperative complications.

Objective According to the fine artery anatomy of the lower lip, we developed an innovative partial-thickness myocutaneous flap based on the vascular network of the submucosal and subcutaneous layers of the lower lip.We attempted to treat the secondary bilateral cleft lip deformities using this innovative cross-lip flap.Methods From July 2009 to June 2015, this new technique was used in 98 patients with secondary bilateral cleft lip deformities.The central defects usually occurred in these patients.The defects were reconstructed partially or completely according to the severities of the defects.The operative procedures were as follows: The split flap was elevated from the posterior portion of the oris orbicularis muscle after the inferior labial arteries were divided.Then the partial-thickness flap was rotated 180 degrees horizontally and inverted 180 degrees upward to the upper lip defect.Results All 98 musculomucosal pedicle flaps were viable.The upper lips were reconstructed according to the severities.Conclusions This myocutaneous cross-lip flap with musculomucosal-pedicle has a more reliable blood supply, better flexibility and plasticity.It is an effective method for aesthetic reconstruction for the secondary bilateral cleft lip deformities.
