Sub-health status in the occupational population showed high incidence. Thus, it is necessary to improve the occupational groups of sub-health status, improve the health level of occupational groups. Shanghai university of traditional Chinese medicine Shuguang hospital treatment center (hereinafter referred to as disease prevention center), based on traditional Chinese medicine disease theory, did a lot of practices on occupational sub-health groups with Chinese medicine prevention and health care. Since 2014, three-year commitment to the Shanghai action plan project, the hospital has constructed a sub-health platform. This article discussed the experience of construction of sub-health platform for the construction of sub-health management system with Chinese characteristics and provided reference for the construction of sub-health management model.

Objective To study the inductive effect of Cortex Periplocae extract(CPE) on apoptosis of human gastric cancer cells BGC-823 and its mechanism.Methods The cell morphology and super-microstructural changes of apoptosis were analysed by Giemsa staining and electric microscope,respectively.The BGC-823 apoptosis ratio,cell cycles,and changes of apoptosis in DNA level were studied by Flow Cytometry and agarose gel electrophoresis.The genes mRNA and protein expression of apoptosis-related genes bcl-2,bax,and survivin were studied by RT-PCR and immunology cell chemistry method.Results After treatment with CPE,BGC-823 cells showed some typical morphologic features and super-microstructural changes of apoptosis.DNA agarose gel electrophoresis showed characteristic "DNA ladder" pattern.Most BGC-823 cells were arrested at G_2/M phase.Some typical subdiploid peaks before G_0/G_1 phase were observed.The apoptotic rate of BGC-823 was 18.9% after 250 ?g/mL CPE treated for 48 h.The gene mRNA and protein expression of bcl-2 and survivin were inhibited by CPE,whereas that of bax was up-regulated.CPE could enhance the life span of S_(180) bearing mice in a dose-dependent manner.Conclusion(CPE can) inhibit the tumor growth by arresting the BGC-823 cell cycle at G_2/M phase and inducing BGC-823 apoptosis.Its mechanism is related to the inhibition on gene mRNA and protein expression of bcl-2 and survivin,and enhancement of those of bax.

Objective To study the outcomes of nasopharyngeal carcinoma treated by late-course 3-dimentional conformal radiotherapy(3DCRT). Methods 37 primary nasopharyngeal carcinomas were involved into the CRT group. A total dose of 70 Gy to 74 Gy was delivered by using the conventional method (36 Gy) and late-course 3DCRT technique (34 ~ 38 Gy). This group was matched with a same number of patients who were treated with conventional method alone (Routing group). The treatment results and acute toxicity between the two groups were analyzed. Results The complete response (CR) rate of primary tumor was achieved 100 % in CRT group and 86 % in routing group, respectively. The CRT group had severe mucositis and peripheral neuropathy, but the difference was not statistically significant. There was no difference in the overall survival between the two groups. Conclusion Late-course 3DCRT is an effective method in the treatment of primary nasopharyngeal carcinoma.

Objective To scrutinize the positioning accuracy and reproducibility of the cone-beam computed tomography system in combination with the six-degree couch table (Hexapod Robot Treatment Table, HRTT). Methods The mechanical stability of the X-ray volume imaging (XVI) system was tested,in terms of the reproducibility. And the influence of the moveable parts, including the KV panel and the source arm, on the accuracy of the XVI image registration was analyzed. The accuracy between the bone and grey value registration was compared using a head-and-neck phantom. The accuracy of the HRTT for translational, rotational, and a combination of translational and rotational corrections was investigated in consecutive measurements. Results The performance of XVI system itself was stable with translational and rotational error of below 0. 4 mm and below 0. 3°, respectively. The mean position accuracy of the XVI system in combination with the HRTT summarized over all measurements was below 0. 6 mm and below 0. 4° for translational and rotational corrections, respectively. The grey value match was more accurate than the bone match. Conclusions The XVI image acquisition and registration procedure were highly reproducible.Both translational and rotational positioning errors can be corrected very precisely with the HRTT. The HRTT is therefore well suited to complement CBCT to take full advantage of position correction in six degrees of freedom for image guided radiotherapy.

ObjectiveTo investigate whether the T1-weighted dynamic contrast-enhanced perfusion magnetic resonance imaging (DCEPMRI) technique can help to delineate the clinical target volume of brain glioma patients.MethodsThe DCE T1-weighted images from 28 glioma patients were collected after GdDTPA was injected.After the acquired images were processed and analyzed using modified Tofts-Kermode'two compartment analysis model and de-convolution method,the value and its pseudo mapping of quantitative parameter Ktrans related to microvascular permeability were obtained.The tumor size in the largest diameter slice measured both in routine enhanced MRI and Ktrans mapping of T1-weighted DCEPMRI were compared.ResultsThe vascular permeability and tumor infiltration was lower in low grade glioma,the difference of the tumor size between T1-weighted DCEPMRI and routine enhanced MRI reached 0.2％ -0.3％ there was significant difference of tumor size between T1 -weighted DCEPMRI and routine enhanced MRI ( grade Ⅰ and Ⅱ grade with 2.93 cm2∶2.46 cm2(t=6.90,P=0.000) and 4.18 cm2∶3.21 cm2(t=10.22,P=0.000) ).While in high grade glioma,the vascular permeability and the tumor infiltration were higher,the difference of the tumor size between T1-weighted DCEPMRI and routine enhanced MRI reached 25％ - 26％( the size of grade Ⅲ and Ⅳ were 6.46 cm2 vs 5.48 cm2 ( t =10.83,P =0.000) and 8.26 cm2 vs 6.52 cm2(t =18.53,P =0.000) ).ConclusionsThe pseudo mapping of quantitative parameter Ktrans related to microvascular permeability acquired by T1-weighted DCEPMRI reflect the infiltrating circumscription in glioma,T1-weighted DCEPMRI can provide more information in delineation the clinical target volume,and it can be used as a new method for tumor volume evaluation.

Chronic neck pain is a common chronic musculoskeletal disorder. Research on neck muscle fatigue contributed to the understanding the pathogenesis of chronic neck pain. The influences caused by the neck muscle fatigue, such as the change of cervical proprioception and balance, could easily lead to chronic injury. Changes in morphology and recruitment strategy of cervical muscle could decrease muscle endurance, which bring about further damage. Targeted therapy and training can relieve muscle fatigue, improve muscle function, and reduce the recurrence rate. Surface electromyography has unique advantages in the evaluation of cervical muscle fatigue. The assessment of muscle fatigue could provide for assistance to the treatment and curative effect of chronic neck pain.

Objective To explore the clinical diagnostic value of high frequency ultrasound on finger parenchyma tumor. Methods Twenty-two patients with finger parenchyma tumor were analyzed retrospectively by clinical and ultrasonographic characteristics including location, size, shape, echo, and color flow signals of tumors. Those findings were compared with pathological data after surgery. Results Out of 22 parenchyma tumor patients, tendosynovial giant cell tumor were present in 7 patients, fibrous tumor in 3 patients,glomus tumor in 5 patients, and ganglia in 7 patients. Differences between ultrasonographic appearances and pathologic features were found in parenchyma tumor. The tendosynovial giant cell tumors were demonstrated plentiful color flow signals and heterogeneous echoic mass without capsules. There was not found color flow signal but an intact membrane in tendosynovial fibrous tumors. Glomus tumors were hypoechoic with an intact membrane, abundant color Doppler signals, and Ⅲ level was classified by Alder. Ganglia were expressed in cystic structure. Conclusions Characteristic features of ultrasonographic appearance were found in different kind of parenchyma tumors. High frequency ultrasound is an effective method to diagnosis finger parenchyma tumor.
