Objective To evaluate results of double eyelid operations with different incisions.Methods 100 patientswere selected randomly from out-patients that accepted double eyelid operation.Half of them were objected to double eyelid operation through a palpebral marginal incision.Incision was designed along the palpebral margin,close to boots of eyelashes.Most of the subcutaneous tissues was cut and removed,and then dermis and tarsal plate were fixed with 5 stitches of suture.About 1-3 mm wide of skin along superior margin was removed reasonably.In another 50 cases.double eyelid operation was performed with conventional incision.Incision was designed 6-8 mm far from the palpebral margin.Most of the subcutaneous tissues was removed.and then dermis and tarsal plate were fixed with 5 stitches of suture.Results Postoperative results were evaluated 5 days and 1 month after operation respectively.Postoperative double eyelid shapes were all satisfled in two groups.Swollen eyedids and scar were more inconspicuous in the cases with the palpebral-marginal incision without impairment on eyelashes.Conclusion Compared with double eyelid operation with conventional incision,blepharoplasty with palpebral margin incision has the same results but with lighter impairment,milder hydropsia and more inconspicuous scar.The key point of this procedure is the fixation of dermis and tarsal plate,keeping a good radian of double eyelid line.

Objective To explore the safety of the mobilization of peripheral blood stem cells(PBSC)by granulocyte colony-stimulating factor(G-CSF)in elderly donors.Methods 28 peripheral arteriosclerotic occlusive disease(PAOD)elderly patients(aged≥60 years),and 29 healthy sibling young/adult donors(aged＜60 years)for peripheral allogenic stem cell transplantation were included.Blood samples were collected immediately before starting G-CSF and prior to PBSC collection to analyze the following parameters:the WBC counts,fibrinogen(FIB),D-dimer (D-D),thrombin antithrombin complex(TAT),antithrombin(AT)and yon Willebrand factor antigen(vWF:Ag). Results It had a very significant increase in D-D and vWF:Ag and a very significant decrease of AT(P＜0.01),af- ter mobilization by G-CSF,and a increase in FIB and TAT were also observed(P＜0.05,P＜0.01)in elderly group.In the young/aduh group,the increase in FIB was significant(P＜0.05).The elevating extent of D-D and TAT after G-CSF administration was significantly higher in elderly group than that in young/adult group(P＜0.05).Compared to young/adult group,there was a significant increase in thrombotic events and cerebrovascular ac- cident(P＜0.05).Conclusion In PBCS donorsreceiving G-CSF it reveals activation of both coagulation and en- dothelial cells and inhibition of anticoagulant system that can favor the developing of thrombotic events,which is more remarkable in elderly donors.Therefore a careful monitoring for coagulation system should be considered in those elderly cases.

Objective To understand the current state of community nurses in Jilin Province and its nursing training so as to provide basis for constructing community nursing training system. Methods 583 community nurses from community health care service centers (stations) in three cities of Jilin Province were investigated with cluster random sampling method to acquire their proficiency level of community nursing knowledge and its demand. Results Common basic nursing knowledge was best mastered by community nurses (63.8%), while knowledge about scientific research was worst mastered (13.6%). Community nurses who were young, in low positions, with work experience for 5 to 9 years, mastered the knowledge worse, 42.9% of them did not attend training. The commonest training problem was that the training period was too short (64.6%); the highest demand was common diseases training for the elderly. Conclusions Nursing training is an important way to improve overall quality of community nurses in the light of unbalance status of their quality in our province and training not being put into place.

OBJECTIVETo establish a method for studying efficacious materials of traditional Chinese medicines from an overall perspective.

METHODCarthamus tinctorius was taken the example. Its major components were depleted by preparing liquid chromatography. Afterwards, the samples with major components depleted were evaluated for their antioxidant effect, so as to compare and analyze the major efficacious materials of C. tinctorius with antioxidant activity and the contributions.

RESULTSeven major components were depleted from C. tinctorius samples, and six of them were identified with MS data and control comparison. After all of the samples including depleted materials are compared and evaluated for their antioxidant effect, the findings showed that hydroxysafflor yellow A, anhydrosafflor yellow B and 6-hydroxykaempferol-3, 6-di-O-glucoside-7-O-glucuronide were the major efficacious materials.

CONCLUSIONThis study explored a novel and effective method for studying efficacious materials of traditional Chinese medicines. Through this method, we could explain the direct and indirect contributions of different components to the efficacy of traditional Chinese medicines, and make the efficacious material expression of traditional Chinese medicines clearer.

Objective To investigate the value and clinical significance of congenital heart diseases (CHD)detection in twins.Methods A total of 1103 twins were included in this study(127 twins were at high risk for CHD).The fetal hearts were scanned by ultrasound using Yagel's heart examination method. Autopsies were done when the pregnancy was terminated.And blood samples from fetal hearts or umbilical veins were used to evaluate fetal chromosomes.A close follow-up was conducted for normal heart cases and another heart examination was done within three months after birth.Results(1)12 twins(1.09%,12/ 1103)had CHD.Among them,4 cases were from the high risk for CHD group(33.3%,4/12),and 8 cases(66.7%,8/12)were from the low risk pregnancy group.(2)Two twins suffered from the same CHD (one pair were both TOF,and the other pair were both rhabdomyoma).One pair of twins had different abnormalities(one baby was TOF,and the other was duodenal atresia with a normal heart).All three pairs of twins chose termination and autopsies were conducted.Unanimous conclusions between prenatal ultrasound and autopsy were obtained.Nine twins were CHD in one baby and a normal heart in the other baby.Seven of them had the same conclusion after delivery.(3)Two twins with CHD were found with fetal abnormal chromosome.(4)1091 cases were not found having any abnormality,however,one fetus from one twin pair was diagnosed with ventricular septal defect(VSD)with abnormal chromosome after birth,and one fetus from another twin pair had patency of ductus arteriosus after birth.(5)The sensitivity of Yagel's heart examination was 82.4% and specificity was 100% in twins.Conclusion Yagel's heart examination is an effective and time-saving method to scan fetal hearts in twins.

Objective To analyze the complications of coronary rotational atherectomy and to evaluate the safety of the procedure. Methods We evaluated the procedural and angiographic outcomes of 248 consecutive procedures to rotational atherectomy between January 2000 and October 2016. Results 27 cases(10.9％)were found to have rotational atherectomy related complications. Among these 27 cases,coronary spasm occurred in 2 cases(0.8％),no reflow in 8 cases(3.2％), coronary dissection in 5 cases(2.0％),burr entrapment in 6 cases(2.4％),wire breakage in 3 cases(1.2％), and coronary perforation in 3 cases(1.2％). There were no death,acute myocardial infarction and emergent coronary bypass graft.14 case(5.6％)had PCI-related myocardial infarction during hospital stay.In-hospital major adverse cardiaccerebral event(MACCE)rate was 5.6％. Conclusions Coronary rotational atherectomy can be performed with high success rates and procedure-related complications are rare.

Endoplasmic reticulum (ER) stress occurs in macrophage-rich areas of advanced atherosclerotic lesions and contributes to macrophage apoptosis and subsequent plaque necrosis. The purpose of the present study was to investigate the effects of caveolin-1 (Cav-1) on ER stress-induced apoptosis in cultured macrophages and the underlying mechanisms. RAW264.7 cells were incubated with thapsigargin (TG) to establish ER stress model. And Cav-1 expression was detected by Western blot. After being pretreated with filipin(III), a caveolae inhibitor, RAW264.7 cells were assayed with flow cytometry and confocal laser scanning microscopy to detect cell apoptosis. Moreover, p38 mitogen-activated protein kinase (MAPK) phosphorylation and C/EBP homologous protein (CHOP) expression were detected with Western blot. The results showed that Cav-1 expression was markedly increased at early stage of TG treatment (P < 0.05) and then decreased with prolonged or high dose TG treatments. The increasing of Cav-1 expression induced by TG in RAW264.7 cells was abolished under inhibition of caveolae by filipin(III) (P < 0.05). The effect of TG on apoptosis of RAW264.7 cells was further augmented after pretreatment with filipin(III) (P < 0.05). Western blotting showed that MAPK phosphorylation induced by TG was inhibited by filipin(III) in RAW264.7 cells (P < 0.05), whereas CHOP remained unchanged (P > 0.05). These results suggest that Cav-1 may play a critical role in suppressing ER stress-induced macrophages apoptosis in vitro, and one of the mechanisms may be correlated with the activation of p38 MAPK prosurvival pathway.

OBJECTIVETo study the pathogenic bacteria of lower respiratory tract infection (LRTI), and age and gender distribution and drug resistance of the pathogenic bacteria in children.

METHODSSputum specimens for bacterial cultures were collected in sterile tubes from all of the children with LRTI who had been admitted to the Children's Hospital of Zhejiang University between August 2001 and July 2002. Antibiotic susceptibility tests were performed using the Vitek system, the Kirby-Bauer diffuse method and the Etest method after bacteria were identified.

RESULTSAmong the 4,238 patients with LRTI during the study period, 1,181 patients were bacteria-positive, with a positive rate of 27.9%. Streptococcus pneumoniae (S. pneumoniae) was the most common (222 strains), followed by Haemophilus influenzae (H. influenzae) (216 strains), Klebsiella pneumoniae (K. pneumoniae) (216 strains), Escherichia coil (E. coli) (169 strains) and Staphylococcus aureus (S. aureus) (89 strains). The isolation rate of S. pneumoniae in females was significantly higher than in males (6.2% vs 4.7%; P < 0.05). However, the isolation rates of K. pneumoniae and S. aureus in males were higher than in females (5.1% vs 4.1% and 2.5% vs 1.5%, respectively; P < 0.05). A higher incidence of LRTI due to S. pneumoniae and H. influenzae was found in the 1-3 years group, while the incidence of LRTI due to K. pneumoniae, E. coli, S. aureus and E. cloacae was higher in patients under 1 year of age. Antibiotic susceptibility tests showed that rates of penicillin non-susceptible S. pneumoniae, ampicillin resistant H. influenzae, oxacillin-resistant S. aureus and ESBL-positive K. pneumoniae and E. coli were 55.0%, 16.5%, 41.2%, 42.6% and 4.5%, respectively.

CONCLUSIONSS. pneumoniae, H. influenzae, K. pneumoniae, E. coli and S. aureus were common pathogens of LRTI in children. The infection rate varied with age and gender. Antibiotics for treating LRTI should be selected based on the drug susceptibility test.

The rice water weevil, Lissorhoptrus oryzophilus Kuschel, has two generations in southern Zhejiang, China. To determine oogenesis in first-generation females (summer females) and its relations to temperature, females were collected from a rice field in early and mid-July and reared on young rice plants at 28, 31 and 34 degrees C in the laboratory. Percentage of females having oocytes, number of oocytes of different stages (stage-I, from early previtellogenesis to middle vitellogenesis; stage-II, late vitellogenesis; and mature-oocyte stage), and length of ovarioles were determined every 10 d of feeding. At each temperature, oogenesis took place in over 40% of females after 20~40 d of feeding, but only 0.0~3.3 stage-I, 0.0~0.8 stage-II and 0.0~1.1 mature oocytes were observed at each observation date. Temperature had significant effect on number of stage-I oocytes but not on number of stage-II and mature oocytes in early July females; temperature had no significant effect on number of oocytes of either stage in mid-July females. Conclusively, in southern Zhejiang, summer L. oryzophilus females have great potential to become reproductive on rice, but their oogenesis activity is very low, with the overall procedures little affected by temperature.

OBJECTIVEFibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant inherited disease caused by mutations of ACVR1 gene and can be inherited from either mother or father. FOP is characterized by the presence of malformations of the big toes and of progressive extra-skeletal ossification. Direct sequence analyses of genomic DNA have demonstrated that there is an identical single nucleotide substitution (c617G-->A, R206H) in the glycine-serine (GS) activation domain of ACVR1 gene, responsible for all affected individuals reported so far. We report a Chinese girl with typical FOP characteristics, in whom the same mutation in ACVR1 was identified.

METHODSClinical diagnosis was based on physical examination, radiological findings, and biochemical tests. For mutation detection, peripheral blood was obtained with informed consent from the patient and the parents. Genomic DNA was extracted from peripheral blood using standard method. Exon 4 of ACVR1 was amplified by polymerase chain reaction (PCR), and the PCR products were subjected to automatic DNA sequencing.

RESULTSThe affected girl is 3-year-old and showed typical clinical manifestations of FOP. She had malformations of the halluces at birth and subsequently progressive extra-skeletal ossification developed at the age of 8 - 9 months. Then, she gradually developed stiffness of the knee joint and neck but remained ambulant. Radiographic changes were observable, e.g., the extra-skeletal ossification was found at cervical spine. Her mother has congenital malformations of the halluces, but had no postnatal progressive extra-skeletal ossification. Her father and other family members are normal. With direct sequencing of the PCR products, a G to A substitution at c617 of ACVR1 (R206H) was detected in the patient only but not in her parents. Paternity analysis suggested that it is a de novo mutation.

CONCLUSIONThis is the first case reported in a Chinese patient with FOP in the mainland of China, which was confirmed by direct sequencing. Although sporadic cases of FOP have been reported in diverse geographic and ethnic group, the mutations of ACVR1 c617 (R206H) are identical up to now. The presence of mutation hot spot facilitates molecular diagnosis in clinical practice. Genetic detection is important for FOP patients to avoid misdiagnosis and further damages, including those from medical intervention.
