[Methods]Thirty patients with tuberculosis of the lower cervical spine underwent anterior decompression and fusion.There were 22 male and 8 female with the age from 24 to 58 years(mean age,37 years).The involved area included 2 vertebral bodies in 21 patients,3 vertebral bodies in 9 patients.Combined chemotherapy was delivered to each patient for at least three weeks preoperatively.There were 5 patients with Frankel Grade B,5 with Grade C,13 with Grade D and 7 with Grade E.The mean kyphosis angle were 12?.[Results]The patiets stood surgery well.The operation time was 70～100 min and the bleeding during operation was 50～150ml.There was no postoperative complication.All patients were followed up for 24～36 months.At the last follow-up visit,5 cases with Frankel Grade B improved to Grade D,3 cases with Grade C improved to Grade D,2 cases with Grade C improved to Grade E,13 cases with Grade D improved to Grade E.There was no breakage of nails or failure of the internal fixation during the follow up.Stable bone union was observed in all cases and the average time required for fusion were 6.5 months.[Conclusion]Anterior debridement and autograft with internal fixation is a safe and effective method for treatment of the lower cervical tuberculosis.

Objective: TO evaluate the effect of custom-made artificial total knee prosthesis replacement on pathological fracture of distal femur caused by giant cell tumor of bone. Methods." A total of 12 knees of 12 patients with pathological fracture of distal femur caused by giant cell tumor of bone were treated with cus-tom-made artificial total knee prosthesis replacement. There were 5 males and 7 females aged from 23 to 40 years (34.2 years on average). Results: All patients tolerated surgery very well. The surgical duration was 120～ 180 rain and the intraoperative bleeding was 500 ～ 900mL. The drainage tube was taken out in 5 days after surgery. The postoperative drainage volume was 300 ～ 700mL. There were no postoperative complica-tions. The postoperative X-ray examination showed that all of the prosthesises were in the right position. Lo-cal pain disappeared in all patients after surgery. The pathological examination identified all the patients with giant cell tumor of bone. All patients were followed up for 18 ～ 30 months (24 months on average). No recur-rence was observed after surgery. No infection or implant loosening occurred during the follow up. According to the Enneking assessment system of function after limb salvage surgery, the mean Enneking scale was 23.8 points (ranged from 15 to 28 points) at the last follow-up visit. Conclusion: Custom-made artificial total knee prosthesis replacement can achieve a high satisfactory rate in clearance of lesion and restoring function of the knee in patients with pathological fracture of distal femur caused by giant cell tumor of bone, improving patients' quality of life.

Objective To evaluate impacts of Community Health Reform Pilot in Bao'an District,Shenzhen,on the staff satisfaction in community health centers.Methods Guanlan and Xixiang Street were chosen as treatment group and Songgang Street as comparison group.Date that one year before and after community reform was retrieved from Electronic Information System both from two groups.Double Differences was employed to estimate the impacts of intervention on the staff satisfaction.Results Community Health Reform program resulted in relieving staff financial stress and occupational stress by 42.4％(P＜0.001)and 46.4％ (P＜0.001)respectively and increasing the sense of equity,the sense of achievement,job satisfaction by 67.7 ％ ( P ＜ 0.001 ),54.5 ％ ( P ＜ 0.001 ) and 14.4 ％ ( P ＜ 0.05 )respectively.Conclusion The community reform in Bao 'an district has impact on increasing job satisfaction in treatment group.

The system of first contact in community health institutions, as the core element of hierarchical di-agnosis and treatment system, is of great importance for reforming successfully China’ health service system. The sys-tem of first contact in community health institutions implemented among labor workers in Shenzhen City plays an im-portant role in patients ’ distribution and the interested parties can accept this mandatory system. Campared with Shenzhen City, the level of services is enough to meet patients’ primary health demands in some cities which the com-munity health service develops well, and it should be thought highly of the mandatory in the process of policy imple-mentation in order to ensure the implementation effect.

We investigated the molecular characteristics of the full-length genome of 14 dengue serotype 1 virus (DENV-1)strains isolated in Sino-Myanmar border region in Yunnan Province,China during 2013-2015.Isolation of dengue virus was using C6/36 cell culture method.Viral RNA was extracted from virus isolates,and then the full-length genome was amplified by RT-PCR.The homology and phylogenetic analysis was made on the nucleotide and deduced amino acid sequences by bioinformatics software including ClastalX1.83 and MEGA6 etc.Results showed that fourteen strains of DENV-1 isolated from dengue fever cases,of these,9 strains from Ruili City of Dehong Prefecture,3 from Lincang Prefecture,2 from Kunming City.RT-PCR and sequencing indicated that the full-length genes (10 735 nt) of 14 DENV-1 strains were obtained,and their open reading frame (95-10 271) were coded 3 392 amino acid residues.The genotypes of DENV-1 were revealed by homology and phylogenetic analysis based on structural and non-structural proteins.Thirteen were genotype Ⅰ (G-Ⅰ) (7 from indigenous cases in Ruili and Lincang and 6 from imported case from Myanmar to Ruili,Lincang and Kunming),and 1 G-Ⅲ from imported case from India to Kunming.The phylogenic analysis indicated that the 13 isolates from Yunnan divided into 2 phylogenic subgroups,and they had a closer genetic relationship with the strains isolated from Southeast Asia.The gene sequences of the 13 G-Ⅰ strains have been acquired,the rate of their nucleotide homology and amino acid homology were 97.02 ％-100 ％ and 98.78 ％100 ％ respectively.Compared with 6 strains from Southeast Asia,nucleotide homology and amino acid homology were 96.53％-99.53％ and 97.33％-100％ respectively.Compared with prototype strain (US_Hawaii) of DENV-1,nucleotide homology and amino acid homology were 93.76％-94.45 ％ and 95.86 ％-96.91％ respectively.Compared with US_Hawaii strain,there were 44 and 150 different sites in amino acid of structural and non-structural proteins,respectively.The G-1 of DENV-1 have been popular in Sino-Myanmar border region in Yunnan,2013-2015.They have genetic diversity but multiple transmission sources were from Myanmar,and should strengthen control cross-border spread of dengue fever in this region.It is necessary to further study that change of the amino acid sites of Yunnan strains of DENV-1 is related to its antigenicity and pathogenicity.

This paper reviews the clinical research on the treatment of chronic prostatitis with traditional Chinese medicine in recent years. It is believed that the core of the etiology and pathogenesis of this disease lies in the deficiency of spleen and kidney, dampness heat, phlegm turbid and blood stasis toxin. If the disease lasts for a long time, the spleen and kidney become to the deficiency from excess. The internal treatment of traditional Chinese medicine includes syndrome differentiation, disease differentiation or single prescription, while the external treatment mainly includes herbal bathing, enema, anal administration and acupuncture. Traditional Chinese medicine has advantages in the treatment of this disease. We should continue to study the the mechanism of traditional Chinese medicine for this disease, standardize the syndrome differentiation and treatment and outocmes evaluation, and carry out research on famous prescriptions on prostatitis.
