The paper introduced the practice of family doctor′s contracted service in Zhenjiang,Jiangsu province over the past six years.By exploring the tiered family doctor′s contracted services,namely 3+X teamwork responsible for household health,health insurance contracting with chronic disease patients,and personalized contracts,the city highlights the cornerstone role of primary care in the Healthy Zhenjiang 2015 Campaign.The campaign aims at providing fair,accessible,systematic and uninterrupted health services.Outcomes of the campaign have proved that the 3+X teamwork model helps building acquaintances relationship with residents by means of contracting,hence motivating both the sector and individuals in the health promotion and building a healthy Zhenjiang.

Objective To conduct a hiomechanical comparison of the four common internal fixation methods for the anterior eruciate ligament(ACL)avulsion fractures of displaced tibial eminence.Methods Sixteen fresh cadaver knee joints were used and randomized into four equal groups of four fixation methods:antegrade wiring group, retrograde wiring group,suturation group,and intramedullary screw group.The knee joint specimens were fixed at flexion of 30?and subject to continuous stretch stresses of 30 N,60 N and 90 N respectively on a material testing machine(MTS 858 Bionix test system,USA)which conducted a simulated Lachman test.The specimens were scanned at different angles by a three dimensional laser scanner.Data were recorded and processed by image software to es- tablish three-dimensional structure models of femur,tibia and knee joint.The test results were analyzed statistically on a computer.Results There were no obvious differences between each fixation group in the length change of ACL when the stresses were 30 N and 60 N(P＞0.05).Under 90 N stress,however,the mean length change between the femoral and tibial attachments of ACL was the smallest(4.8?1.7)mm(2.5 to 6.2 mm)in the suturation group(P＜0.05). There were no distinct differences between the intramedullary screw group and the retrograde wiring group in the changes of A CL shift(P=0.214).The average front shift in the retrograde wiring group was(6.2?1.2)mm(4.8 to 8.2 mm) and significantly smaller than that in the antegrade wiring group(P＜0.05).The antegrade wiring group made the largest average front shift under different stresses and its average front shift was(7.2?1.3)mm(5.6 to 8.7 mm). Conclusions The knee joint stability provided by the suturation fixation is distinctly better than that by the other three fixation methods.The antegrade wire fixation provides the poorest knee joint stability.There is hardly any difference between intramedullary screw fixation and retrograde wiring fixation.

Parathyroid carcinoma is a rare sporadic disease.Clinical manifestations include hypercalcemia,increased urinary calcium and urinary calculus,osteoporosis,and pathologic fracture.While this patient complained of pollakiuria,urgency,and painful urination,thus might lead to misdiagnosis or missing of diagnosis of parathyroid carcinoma.This article is herewith presented to call attention to discovery,diagnosis,and treatment of parathyroid carcinoma.

The drugs such as sildenafil adulterated in herbal products and dietary supplements may endanger human health. The number of the new modified derivatives is increasing recently. Based on Q-TOF-MS, a new sildenafil analogue was found. It was isolated and purified by preparative liquid chromatography. Its structure was determined by NMR, as 1-[4-propoxy-3-(6, 7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4, 3-d] pyrimidin-5-yl)phenylsulfonyl]-4-methylpiperazine. Compared with sildenafil, the ethoxy group of the benzene ring moiety was moved to the propoxy group, which had not been reported in China. The mass spectrometric behavior pattern of the structure type was summarized, which can greatly accelerate the structural analysis of novel analogues.

AIM:To study the mechanism of the unique export of one of human basic fibroblast growth factor (hbFGF) forms lacking the N-terminal nuclear localization signal (NLS),we high expressed and purified this hbFGF form in E.coli strain BL21(DE3).METHODS:The cDNA fragment of the hbFGF amplified by polymerase chain reaction (PCR) was cloned into the expression vector pET3c and expressed in BL21(DE3) by IPTG induction.The expressed hbFGF was purified by ionic exchange and heparin affinity chromatography from the supernatant of bacteria lysate.The mitogenic activity was measured by MTT.RESULTS:The expression level of hbFGF in E.coli was about 20% of the total cellular protein.The appreciable mitogenic activity of the purified hbFGF was comparable to that of hbFGF standard.CONCLUSION:The BL21(DE3)/ pET3c expression system could be used to high express hbFGF lacking NLS.The purified recombinant hbFGF was prepared and sufficient for further study.

Objective:To investigate the whole genome characteristics of coxsackievirus A4 (CVA4) circulating in Qingdao city.Methods:Four CVA4 isolates circulating in Qingdao city during 2013 to 2015 were selected. Whole genome sequences of these strains were amplified by one-step reverse transcription-polymerase chain reaction (RT-PCR). Sequence alignment and phylogenetic analysis were performed using MEGA7.0 software package. Genetic recombination analysis was performed using similarity plots 3.5.1 software package.Results:Phylogenetic analysis showed that based on the sequences of the whole genome and P1, P2 and P3 regions, HS312/QD/CHN/2013 and HS605/QD/CHN/2014 strains together with the early domestic isolates belonged to the same clade, while FY218/QD/CHN/2015 strain and CV-A4/P1033/2013/China strain collected in Wenzhou in 2013 formed another clade in each phylogenetic tree. HS144/QD/CHN/2014 strain belonged to the same clade as HS312/QD/CHN/2014, HS605/QD/CHN/2014 and the early domestic CVA4 isolates in the phylogenetic tree based on the P1 region, but formed a separate clade in the phylogenetic trees based on the whole genome, P2 region and P3 region. Genetic recombination analysis revealed that there was genetic recombination between HS144/QD/CHN/2014 strain and the CVA2 strain of CV-A2/P373/2013/China isolated in mainland China in 2013 in the region of 2C-3D (5 081-7 301); FY218/QD/CHN/2015 and CV-A4/P1033/2013/China strains were highly homologous and recombination signal sequences were detected in the region of 2A-2B (3 821-4 161) between the two strains and the CVA2 strain of CV-A2/P373/2013/China.Conclusions:The CVA4 isolates circulating in Qingdao city presented obvious genetic diversity at the genome-wide level.

OBJECTIVETo evaluate the role of undermining orbicularis oculi muscle from Orbital rim for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.

METHODS56 cases of lower eye baggy deformity with tear trough deformity and palabromalar groove were treated with the procedure of stripping eye orbicularis oculi muscle from orbital rim by a transcutaneous approach in lower blepharoplasty. The orbital septum was opened along the arcus marginalis for releasing the orbital fat. Some orbital fat was removed if necessary. Then the inferior edge of the orbital septum fat was reset over the orbital rim so as to smooth the infraorbital groove.

RESULTS56 patients were available for 6 to 18 month's follow-up. 54 patients were quite satisfied with the cosmetic result. One developed lower eyelid retraction and another one showed asymmetrical subcutaneous local uneven after 1 month's. They were all corrected by the second operation after 3 months.

CONCLUSIONSStripping orbicularis oculi muscle from orbital rim plays an important role for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.
