In recent years, translational medicine, which is characterized by advanced concepts and methods, developes rapidly and playes a strategic role in the development of TCM acupuncture and moxibustion. Therefore, it is worth studying by acupuncturists. Through the background, development, features and research model of translational medicine, the present situation and problems of TCM acupuncture research are analyzed. Several cases of translational Chinese medicine and acupuncture are listed with the consideration of the concept of translational medicine. Studies and thoughts on translational acupuncture are expounded as well. Thus, it is suggested that combined with characteristics of acupuncture, the concept of translational medicine should be utilized to instruct the clinical treatment and research of acupuncture, foster researchers of translational medicine as well as establish the related research teams.

Chemical investigation was carried out to study the alkaloids from stems of Nelumbo nucifera and their cytotoxic activities. The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for their cytotoxic activities by MTr method. Fifteen compounds were isolated from the total alkaloids extract and identified as asimilobine (1), isococlaurine (2), N-acetylnorarmepavine (3), crykonisine (4), velucryptine (5), pycnarrhine (6), liriodenine (7), nuciferine (8), nornuciferine (9), armepavine (10), N-methylasimilobine (11), coclaurine (12), N-norarmepavine (13), N-methylcoclaurine (14) and lysicamine (15). Compounds 1-7 and 12-15 were isolated from stems of this plant for the first time, and compounds 2-6 were firstly isolated from the family Nelumbonaceae. Compounds 7-10, 13 and 14 showed significant cytotoxic activities against HL-60 carcinoma cell line with inhibitory ratios of 51.36%, 59.09%, 52.51%, 53.93%, 51.43%, and 64.31% at concentration of 1 x 10(-5) mol x L(-1), respectively.

Naturally occurring mutations in surface proteins of Hepatitis B virus(HBV)usually result in altered hepatitis B surface antigen(HBsAg)secretion efficiency.In the present study,we reported two conserved residues,M75 and M103 with respect to HBsAg,mutations of which not only attenuated HBsAg secretion(M75 only),but also suppressed HBV genome replication without compromising the overlapping p-gene product.We also found M75 and M103 can initiate truncated surface protein(TSPs)synthesis upon over-expression of full-length surface proteins,which may possibly contribute to HBV genome replication.However,attempts to rescue replicationdefective HBV mutant by co-expression of TSPs initiated from M75 or M103 were unsuccessful,which indicated surface proteins rather than the putative TSPs were involved in regulation of HBV genome replication.

Objective To study the dosimetry for copper compensator in IMRT.Methods 10 patients (3 nasopharyngeal carcinoma,4 esophageal cancer,3 colorectal cancer) from IMRT plans made in Oncentra Planning System enrolled in this study.The fluence matrices of each plan were converted into compensator thickness matrices based on attenuation coefficient of copper under 6 MV radiation ray which was measured with ion chamber.While irradiating the homogenous phantom with the intensity modulated plans performed by copper compensator,film was used to measure the planar dose.In the end,γanalysis was carried out between the measured and calculated planar doses with the criteria of 3％ DD/3 mm DTA.Paired t test to MU differences of MLC plans and copper compensator plans.Results The γanalysis results showed the planar dose pass rates of 10 plans lie between 90.2％ and 98.2％,which means the IMRf technique based on copper compensator can meet the clinical needs.The MU for copper compensator IMRT plans is less than the MLC IMRT plans (873.9 vs.975.1,P =0.005).Conclusions Compared to conventional IMRT based on MLC,copper compensator has the advantage of lower requirement of hardware and lower scattering dose in patient.Copper compensator can meet the needs of clinical practice.

This study was aimed to investigate the efficacy, acceptance, complications / adverse events treated with traditional manipulation and bed rest for patients with acute nonspecific low back pain (ANLBP). A total of 60 ANLBP patients were distributed into the Group A/B randomly and equally. Patients in Group A were treated by bed rest absolutely for one week; meanwhile patients in Group B were treated by traditional manipulation for one week. IBM SPSS20.0 was used to analyze the Visual Analogue Scale (VAS), Chinese Oswestry Disability Index (ODI), acceptance, complications / adverse events and others. The results showed that VAS and ODI reduced after one-week treatment in Group A and B (t = 14.67, 11.55, allP < 0.001 andt = 24.80, 15.35, allP <0.001). Differences of VAS and ODI were with significant difference between Group A and B (t = 3.24, 2.75,P =0.002, 0.009). Scores of acceptance and complications / adverse events were with significant difference between Group A and B (t = 2.65,P = 0.01 andχ2= 10.00,P = 0.002). It was concluded that both manipulation and bed rest can alleviatepain due to ANLBP, promote functional recovery. However, traditional manipulation can better improve symptoms, easier to be accepted by patients with less complications / adverse events.

Objective To compare patellar ring,Kirschner wire tension band and patellar ring plus Kirschner wire in fixation for treatment of patella fractures.Methods A retrospective analysis was conducted on the 285 patients with patellar fracture who had been treated between September 2009 and January 2016.They were 155 men and 130 women,with an average age of 45.5 years (from 18 to 70 years).Their fractures included 176 transverse,28 longitudinal split and 81 comminuted ones.They were divided into 3 groups according to their different internal fixation methods:patellar ring fixation (98 cases),Kirschner wire tension band (92 cases),patellar ring plus Kirschner wire fixation (95 cases).The 3 groups were compared in terms of operative time,intraoperative bleeding,fracture healing time,knee function by B(o)stman score at the last follow-up and postoperative complications.Results The operative time in the patellar ring group(58.9 ±6.4 min) was significantly shorter than in the Kirschner wire group (71.8 ± 7.8 min) and in the patellar ring plus Kirschner wire group (74.4 ± 8.0 min) (P ＜ 0.05).There were no statistical significant differences between the 3 groups in fracture healing time and intraoperative bleeding (P ＞ 0.05).The good to excellent rate of knee function at the last follow-up in the Kirschner wire tension band group was 100.0％ (92/92),significantly higher than in the patellar ring group (90.8％,89/98) and in the patellar ring plus Kirschner wire group (91.6％,87/95) (P ＜ 0.017).There was no significant difference in postoperative complication rate between the patellar ring fixation group (2.0％,2/98),Kirschner wire tension band fixation group (1.1％,1/92) and the patellar ring plus Kirschner wire group (2.1％,2/95) (P ＞ 0.05).Conclusion Internal fixation with Kirschner wire tension band has definite curative effect on patellar fractures,showing the advantages of less operative invasion,fewer postoperative complications,better functional recovery of the affected knee joint,and lower price over the other 2 internal fixation methods.

Chinese medicine pairs (CMP) are specific compatibility with traditional Chinese medicine (TCM) theory as principle, which was formed on basis of effect and treatment theory of TCM. The compatibility of CMP can enhance the effect, or reduce the toxicity. So, compatibility effects of CMP were studied from different pharmacology levels including animals, tissues and organs, cell and molecular levels, their synergy and compatibility attenuation were also evaluated with monomer component-component (group) compatibility-single herb-CMP-formulae as the main line, and the action mechanisms were investigated, all of which can provide scientific basis for the clinical applications of CMP and creation of TCM new drugs.

OBJECTIVETo study the expression of phosphatase and tensin homology deleted on chromosometen ten (PTEN) protein, a tumor suppressor gene in breast cancer and its correlation with p27(kip1) and cyclin D1 expression.

METHODSPTEN protein expression, p27(kip1) and cyclin D1 protein expression were detected by immunohistochemical method in paraffin sections from 61 women with primary breast cancer. PTEN protein expression was compared with clinico-pathologic parameters as related to p27(kip1) and cyclin D1.

RESULTSPTEN, being shown in the cytoplasm, was negative in 6.6% (4/61), reduced in 41.0% (25/61) and positive in 52.5% (32/61) samples. PTEN expression level was correlated with axillary lymph node status, loss of estrogen receptor stain, recurrence and metastasis. On univariate analysis, the disease-free survival rate of patients with higher PTEN expression (> 50% cells stained) was better than those with lower expression (P = 0.0101). However, there was no correlation between p27(kip1), cyclin D1 expression or PTEN expression.

CONCLUSIONPTEN, its lower expression being correlated with poor outcome of breast cancer patients, plays a prominent role in breast cancer. p27(kip1) or cyclin D1 may not be the primary downstream genes of PTEN in breast cancer.

Objective To report the clinical effect of free transplanting for soft tissue defects pedieled with high site cutaneous branches of the transverse branch of lateral cirumflex femoral artery.Methods Cu- taneous branches of the descending branch of lateral circumflex femoral artery were found small or abscent in 7 patients.The anterolateral femoral skin flap was pedicled with high site cutaneous branches of the transverse branch to repair the soft tissue defects of the arm,hand,leg and foot,rather than with the descending ones. The size of the flap ranged from 15 cm?6 cm to 28 cm?13 cm,with part muscle valve,iliotibal tract and lat- eral femoral cutaneous nerve.The fractures were performed with internal or external fixation.Results All of the anterolateral femoral skin flap survived well postoperatively in the 7 cases and had good appearance and sensation at one stage.The function of the repaired extremities recovered well.Conclusion The anterolat- eral femoral skin flap pedicled with high site cutaneous branches of the transuvrse branch of lateral circumflex femoral artery has many advantages of good blood supply and large size.The flap was secluding,and can be taken with some muscle and lateral femoral cutaneous nerve.When cutaneous branches of the descending branch of lateral circumflex femoral artery is small or abscent,the anterolateral femoral skin flap with high site cutaneous branches of the transverse branch of lateral circumflex femoral artery is an optimal alternative.

Objective To investigate the current prevailing status of endemic fluorosis in the Yellow River basin of Shandong Province and to provide the scientific evidence for making strategies in prevention and control.Methods Nine counties were chosen to carry out the epidemiological investigation.The content of fluoride in drinking water was determined by F-ion selective electrode and dental fluorosis of children aged 8～12 years old was diagnosed by Deans method.Results Water fluoride content was determined in 1761 fluorosis villages,among which 606 villages had water fluoride content≤1.00 mg/L,accounting for 34.41%(606/1761);1155 villages had water fluoride content＞1.00 mg/L,which accounted for 65.59%(1155/1761).The highest water fluoride content was 11.33 mg/L.Water fluoride content of 618 water-improving and defluoridation projects had been determined,among which 449 projects had water fluoride content≤1.00 mg/L and accounted for 72.65%(449/618),169 projects had water fluoride content＞1.00 mg/L and accounted for 27.35%(169/618),the highest water fluoride content was 5.85 mg/L.The total rate of dental fluorosis of children aged 8～12 years old was 45.03%(25 579/56 804) and the index of dental fluorosis was 0.80. Conclusions In the Yellow River basin in Shandong Province,up to 50.00%in the villages the water fluoride content exceeds the county standard(≤1.00 mg/L).The prevalence of endemic fluorosis in the basin hasn't been effectively controlled.So the counterrneasures for endemic fluorosis should be carried out as soon as possible.
