Objective To investigate efficacy of citalopram on pathological crying after cerebral infarction.Methods 106 patients with pathological crying after cerebral infarction were randomly divided into two groups,treatment group(54 cases) and control group(52 cases).Control group received conventional treatment of cerebrovascular disease.Treatment group taken citalopraml0-20mg orally one time per day for three months based on conventional treatment.The total response rate,effectual time,and Hasegawa Dementia Scale (HDS) scores were compared between two groups after treatment.Results There were significant differences in total response rates (94.4％ and 38.5％,respectively),effectual time(1.98 ± 1.24 and 78 ± 17.95,respectively) and HDS(8.43 ±2.21 and 6.24 ±2.02,respectively) between treatment group and control group (P ＜ 0.01).Conclusion The study suggests that it is effective to treat pathological crying with citalopram and its effect is quick.Citalopram can not only control patient’s pathological crying,but also improve cognitive function.

Objective To construct the eukaryotic expression plasmid of pEGFPC1uPAR gene and explore the effect on the proliferation and invasion ability of Pam 212 cells. Methods The human uPAR cDNA was cloned by PCR, and inserted into the eukaryotic expression plasmid pEGFPC1. After identification of sequencing, the reconstructive plasmid was transformed transiently into Pam 212 cells, then the cell growth and the invasion ability were evaluated. Results The reconstructive plasmid of pEGFPC1uPAR was validated by sequencing. The reconstructive plasmid can promote the growth of Pam 212 cells and enhance the invasion ability. Conclusion The pEGFPC1uPAR plasmid was constructed successfully and uPAR was confirmed to promote the growth and the invasion ability of Pam 212 cells, which lay the foundation for further studies of uPAR in vivo.

Objective To study the effects of sodium bicarbonate (SB) on resuscitation in swine model of asphyxiation cardiac arrest (CA).Methods Thirty-two healthy miniature pigs were randomized (ramdom number) into two groups,the SB group (n =16) and the control group (n =16).Animals in both groups underwent endotracheal tube clamping to induce CA.Once induced,CA left untreated for a period of 8 minutes.At the beginning of initiation of cardiopulmonary resuscitation (CPR),SB (1.0 mEq/kg,diluted to 40 mL) was injected in central venous in SB group and isopyknic normal saline solution was injected in control group.Two minutes following initiation of CPR,defibrillation was attempted until return of spontaneous circulation (ROSC) was achieved or animals died.To assess the SB effects on myocardial metabolism,positron emission tomography (PET) was performed at baseline and 6 after ROSC.To analyze 18F-FDG myocardial uptake identified in PET,the maximum standardized uptake value (SUV) was measured.Results ROSC was 10/16 successful in SB group and only 8/16 successful in control group.The average survival time of SB group was (3.63 ± 0.76) h and that of control group was (2.45 0.70) h.Myocardial metabolism imaging using PET demonstrated that myocardial metabolism injuries in control group were more severe than in SB group at 6 h after ROSC and SUVmax was more higher in SB group than in control group (6 hrs after ROSC:1.32 ± 0.20 vs.1.10 ± 0.14,P =0.035).Conclusions In swine model of asphyxiation CA,SB improve the myocardial metabolism and might raise the possibility of ROSC and have no hypernatronemia.

ObjectiveTo evaluate the effectivenes of continous passive motion(CPM) on limb function in patients after total knee arthroplasty.MethodsThe Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, PEDro, CNKI and VIP were retrieved from the date of establishment of the databases to July, 2010 to collect randomized controlled trials(RCTs). The quality of RCTs was critically appraised and data were extracted by 4 reviewers independently. Meta-analysis was conducted for the eligible RCTs.Results26 RCTs were included. The result of Meta-analysis showed that CPM improved the range of motion (ROM) in active knee flexion and passive knee flexion, eliminate swelling in short term(＜6 weeks) and alleviate pain in short and medium term (less than 6 months). CPM showed no significant difference in improving the ROM in active and passive knee extention and quadriceps strength, and shortening hospital stay.ConclusionThe patients carried out CPM training after total knee arthroplasty can effectively improve limb flexion function, eliminate joint swelling, and relieve pain in the short term. But more high-quality and large-scale RCTs are needed.

Objective To observe the temporomandibular joint spaces changes after the plastic surgery of combined zygoma with mandibular angel.Methods We randomly selected 59 patients with prominent zygoma and mandibular angle,screening periodontal disease,TMJ pain and partial jaw.Bilateral zygomatic arch coarctation,jaw edge of the mandibular angle ostectomy and the mandibular body outer panel split were used.All patients accepted CT scan and three-dimensional reconstruction before operation,10 days after operation and 6 months after operation,and then image analysis softwares were used to measure the line distance of corresponding angle (0°,60°,120°,and 180°)at the TMJ sagittal plane.The 0° (EE 'pitch) and 60° (AA'pitch) represented for pre-space,the 60° and 120° (PP'pitch) was upper-space,the 120° and 180° (SS'pitch) was posterior-space.Results 0° and 60° had the same change trend,which slightly increased at 10 days after operation.The difference before operation and 10 days,6 months after operation were not statistically significant (P ＞ 0.05);120° and 180° had the same change trend,which increased at 10 days after operation.The difference between before operation and 10 days after operation was statistically significant (P ＜ 0.05),but the difference between before operation and 6 months after operation was not statistically significant (P＞ 0.05).Conclusions In the short term after plastic surgery of zygoma combined with mandibular angel,the TMJ upper and posterior spaces are changed,and the interspace reduced.This may indicate that the TMJ has compensatory ability,and short-term changes can return to normal.

Objective To analyze the sequence of microsatellite and the flanking sequence from four populations of Oncomelania hupensis. Methods We cloned 159 SSR-PCR amplification products of a commonly used primer, (CA)8RY, using O. hupensis genomie DNA as template, and sequenced 82 products Results The sequences obtained were novel O. hupensis genomic sequences but not repeat simple sequence. It was observed that 36 out of 82 clones contained microsatellites between priming sites.The flanking sequences of certain microsatellite were invariant. Both (GA/CT). and (TTAGGG/CCCAA)n were found in four populations of O. hupensis. However, (CAA)n were found only in O. hupensis from Fuqing,Fujian province and (TCTCTG), were found only in O. hupensis from Guichi,Anhui province and (GAA/TTC)n, (CAA/TTG)n, (CAT), were found only in O.hupensis from Puge,Sichuan province. Conclusion The results obtained by SSR-PCR should not be interpreted as the amplification of microsatellite loci, and analytical rules similar to those for Random Amplified Polymorphic DNA should be used. SSR-PCR could not make the most of the priority of microsatellite. It seems better to amplify the microsatellites with the primers designed on the basis of the flanking sequence.

The index components contents of different time and different stubbles in honeysuckle were measured by HPLC, and were analysis by using the method of SPSS. Results showed that the content of index ingredients of different time had differences, and firstly decreased, then increased with time. The content of index ingredients of different stubbles had significantly differences, and firstly decreased, then increased with time. The chlorogenic acid contents were 2.059%-3.593%. The luteolosid contents were 0.110%-0.171%. Results indicated that the best picking buds time is before seven o'clock in the morning and evening at before and after seven o'clock, the index component content is higher. Picking buds in spring and at autumn index component content is higher; Picking buds in summer index component content is low. The experiment provides theoretical support for quality control in the whole process of the honeysuckle harvested and comprehensive utilization of honeysuckle.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.

OBJECTIVETo observe the therapeutic angiogenesis effect of naotai recipe (NR) on local ischemia/reperfusion (I/R) injury of rats by observing signaling pathway of hypoxia-inducible factor-lα (HIF-1α) and vascular endothelial growth factor (VEGF).

METHODSTotally 120 Sprague-Dawley (SD) rats were randomly divided into 4 groups, namely, the normal control group (n =12), the sham-operation group (n =12), the I/R model group (n =48), and the NR group (n =48). Cerebral I/R injury models were established using thread suture method. Rats in the I/R model group and the NR group were sub-divided into 4 sub-groups according to the 1st, 3rd, 5th, and 7th I/R day (n =12). The phenomenon of neovasculization was observed by immunofluorescence staining. The protein and mRNA expression levels of HIF-la, VEGF-A, and VEGFR II receptor were detected by RT-PCR.

RESULTSThere were a large amount of labels for neovasculization in the ischemic area of the NR group. Double-immunofluorescence labeling [vWF (red) and BrdU (green)] was observed in the NR group. Compared with the model group, the HIF-1α protein expression was obviously enhanced on the 1 st day of I/R (P <0.01), and the VEGF protein expression started to enhance on the 3rd day in the NR group (P <0.01). The VEGFR protein expression level was the highest in the NR group on the 5th day of I/R (P <0.01). The protein expression of VEGF and HIF-1α started to decrease on the 7th day of I/R.

CONCLUSIONNR could strengthen angiogenesis after I/R by elevating the expression of HIF-lα and activating HIF-lα/VEGF signaling pathway.

OBJECTIVE: Anti-Ro52 antibodies are frequently co-occur with other myositis-specific and myositis-associated autoantibodies, we here to study this phenomenon in Chinese patients suspected with inflammatory myopathies. METHODS: In the study, 1 509 patients clinically suspected with inflammatory myopathies were tested for 11 kinds of myositis-specific and myositis-associated autoantibodies (including: anti-Jo-1, PL-7, PL-12, EJ, OJ, Mi-2, SRP, Ku, PM-Scl 75, PM-Scl 100, and Ro52 antibo-dies) by line-blot immunoassay from 2010 to 2016 in Peking University First Hospital. This retrospective study was to analyze these results to reveal the characteristics of anti-Ro52 antibodies co-occuring with other myositis autoantibodies. The data were analyzed using SPSS 17.0 and Graph Pad PRISM for Chi-square test, independent t-test, Pearson's correlation analysis, and drawing statistical graphs. Significance level was set at P < 0.05. RESULTS: The positive rate of anti-Ro52 antibodies was 18.3% (276/1 509 cases), which was the most frequently detected myositis antibodies in our center. 51.8% (143/276) of the patients with anti-Ro52 antibodies were combined with the other myositis antibodies, and the most common co-occurred antibodies were anti-SRP antibodies (18.8%, 52/276), and the second common co-occurred antibodies were anti-Jo-1 antibodies (13.0%, 36/276). Anti-Ro52 antibodies were the most common antibodies that co-occurred in other myositis antibodies positive patients except in anti-OJ antibodies positive group. The co-positive rate with anti-Ro52 antibodies was the lowest in anti-PM-Scl 75 positive group (30.4%, 31/102), and the highest in anti-EJ positive group (80.0%, 12/15). The positive rate of anti-Ro52 antibodies in anti-synthase antibodies (including anti-Jo-1, EJ, OJ, PL-7, and PL-12 antibodies) positive group was 57.3% (75/131), which was significantly higher than that in the other antibodies (including: anti-Mi-2, SRP, Ku, PM-Scl 75, and PM-Scl 100 antibodies) positive group with 35.2% (119/338) (χ²=18.916, P < 0.001). The intensity of anti-Jo-1, EJ, and SRP antibodies in the group of the patients that co-occurred with anti-Ro52 antibodies was significantly higher than that in the other group without anti-Ro52 antibodies respectively (P < 0.05). The intensity of anti-SRP antibodies was significantly correlated with that of anti-Ro52 antibodies (r=0.44, P=0.001). CONCLUSION Anti-Ro52 antibodies were commonly associated with other myositis-specific and myositis-associated autoantibodies, especially with anti-synthase antibodies, and the co-presence of anti-Ro52 antibodies may be correlated with the myositis antibody intensity.
