Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

OBJECTIVETo study the major metabolites of antitumor lead compound T-OA (oleanolic acyl-3, 5, 6-trimethyl pyrazine-2-methyl ester) in rat urine, in order to preliminarily infer its metabolic mode in rats.
METHODRat urines of the blank group, the raw material group (ligustrazine TMP and oleanolic acid OA Moore equivalent) and the T-OA group were collected and freeze-dried; Solids were extracted by ethyl acetate; And then the extracts were re-dissolved with acetonitrile. HPLC-HRMS coupling technique was adopted to find the potential mass spectrum peak under ESI(+) (see symbol) ESI(-) modes. Metabolite-related information was obtained by comparing the three groups of spectra.
RESULTOne metabolite of OA and two metabolites of TMP were identified in the raw material group; none metabolite of T-OA but one phase II metabolite was detected in the T-OA group.
CONCLUSIONIt is the first time to identify one phase II metabolite of T-OA and one phase II metabolite of OA were identified in rat urine. On that basis, the researchers preliminarily inferred that T-OA does not show the efficacy in the form of raw material. The HPLC-HRMS method established could be used to identify metabolites of related derivative structures. This paper could also provide certain reference for designing pro-drugs based on oleanolic acid.

BACKGROUNDAlthough the early clinical outcomes of total knee arthroplasty (TKA) using minimally invasive surgery techniques have been widely described, data on the mid- to long-term outcomes are limited. We designed a retrospective study to compare the two most common TKA techniques - The modified quadriceps-sparing (m-QS) approach and the mini-medial parapatellar (MMP) approach - In terms of the clinical and radiographic parameters, over a minimum follow-up period of 5 years.
METHODSThe m-QS approach was used in 31 knees and the MMP approach, in 36 knees. Knees in both groups were compared for component position and alignment, knee alignment, length of the skin incision, range of motion, Visual Analog Scale score, muscle torques, Knee Society Score, Western Ontario and McMaster Universities Osteoarthritis Index, and number of complications.
RESULTSThere were no major intergroup differences in any of the clinical and radiographic outcomes assessed at the final follow-up examination.
CONCLUSIONSOn the basis of numbers studied, the m-QS group, which requires more technique, showed equivalent results with the MMP group in the postoperative 5 years. Preservation of the extensor mechanism in the m-QS approach could not ensure any improvement in the clinical outcomes during the mid-term follow-up duration.

OBJECTIVETo observe the therapeutic effect of CDglyTK gene mediated by radiation-inducible promoters in the treatment of buccal carcinoma in Golden Hamster.
METHODSAnimal models of buccal carcinoma in golden hamster were established by painting 0.5% dimethyl-benzanthracene. The plasmids pcDNA (+) 3.1/E-CDglyTK were transfected into tumors by lipofectamine. 24 h later, the tumors were exposed to 3 Gy irradiation. Animals were monitored at regular intervals for volume of tumors. CDglyTK mRNA was assayed by RT-PCR. Apoptosis and proliferating cell nuclear antigen were detected respectively by in situ end-labeling and immunohistochemical methods.
RESULTSCompared with control groups, the tumor was suppressed obviously by CDglyTK gene therapy combined with 3 Gy induction radiation. The expression of CDglyTK gene could be detected by RT-PCR in the transfected tumor, and up-regulation of CDglyTK expression was found in tumor exposed to radiation (P < 0.05). There was significant difference in apoptosis index or proliferation index between tumor without irradiation and tumor with irradiation (P < 0.05).
CONCLUSIONSThe radiation-inducible promoter can be served as a molecular switch to regulate the expression of CDglyTK gene in buccal carcinoma in golden hamster, and low dose induction radiation can significantly improve the therapeutic effects.

BACKGROUNDSeveral reports have shown the progression of articular cartilage degeneration after anterior cruciate ligament (ACL) reconstruction. No report has been published about the cartilage comparing changes after single-bundle (SB) and double-bundle (DB) ACL reconstructions. The purpose of this study was to evaluate the articular cartilage changes after SB and DB ACL reconstructions by second-look arthroscopy.
METHODSNinety-nine patients who received arthroscopic ACL reconstruction were retrospectively reviewed at an average of 14 months after reconstruction, 58 patients underwent SB ACL reconstruction and 41 patients underwent DB ACL reconstruction. Hamstring tendon autografts were used in all patients. Second-look arthroscopy was done in conjunction with the tibial staple fixation removal at least one year after the initial ACL reconstruction. Arthroscopic evaluation and grading of the articular cartilage degeneration for all patients were performed at the initial ACL reconstruction, and at the second-look arthroscopy.
RESULTSThe average cartilage degeneration at the patellofemoral joint (PFJ) was found significantly worsened after both SB and DB ACL reconstructions. This worsening were not seen at medial tibiofemoral joint (TFJ) and lateral TFJ. Grade II cartilage damage was the most common. At second-look arthroscopy, the average patellar cartilage degeneration was 1.14 ± 0.14 (at first look 0.52 ± 0.11) for the SB group, and 1.22 ± 0.15 (at first look 0.56 ± 0.12) for the DB group. The average trochlear cartilage degeneration was 1.05 ± 0.16 (at fist look 0.10 ± 0.06) and 0.66 ± 0.17 (at fist look 0.17 ± 0.09), respectively. The average patellar cartilage degeneration showed no significant difference in both groups. However, the average trochlea cartilage degeneration in DB group was significantly less than in SB group.
CONCLUSIONSPatellofemoral cartilage degeneration continued to aggravate after ACL reconstruction. DB ACL reconstruction could significantly decrease the trochlea cartilage degeneration compared with SB ACL reconstruction.

OBJECTIVETo evaluate the relationship between A46G and C79G polymorphisms in the β2-adrenergic receptor (ADRB2) gene and the incidence of essential hypertension (EH) among the Han Chinese population.
METHODSWe conducted a computer retrieval of PUBMED, EMBASE, CNKI, Wanfang and VIP databases prior to May 2010. Articles investigating the relationship of EH and ADRB2 gene polymorphism of Han group were found through literature search, including 15 articles on A46G and 10 articles on C79G. According to the including and excluding criteria, a Meta-analysis was conducted in EH and ADRB2 gene polymorphism of A46G and C79G. The association was examined by RevMan4.2 software through quantitative analysis.
RESULTSEight articles on A46G polymorphism (including 1078 EH cases and 788 control subjects) and six articles on C79G polymorphism (including 1367 EH cases and 1006 control subjects) were included in the current study. Meta-analysis showed that there was a significant association between A46G polymorphism and EH: genotype GG/(AA + AG) (fixed-effected model, OR = 1.35, 95%CI = 1.04 - 1.74, P = 0.02), genotype GG/AA (fixed-effected model, OR = 1.41, 95%CI = 1.06 - 1.89, P = 0.02). No significant association was found between C79G polymorphism and EH of Han group in China: G/C allele comparison (random-effected model, OR = 0.88, 95%CI = 0.55 - 1.39, P = 0.57).
CONCLUSIONSignificant association was found between A46G polymorphism of ADRB2 gene and EH, whereas no association could be found between C79G polymorphism and EH among Han Chinese population.

OBJECTIVE:
To compare the clinical efficacy differences between WANG Ju-yi 's meridian diagnosis method combined with Bobath rehabilitation training and Bobath rehabilitation training alone for post-stroke shoulder-hand syndrome (SHS) typeⅠ.
METHODS:
A total of 106 patients with post-stroke SHS typeⅠwere randomly divided into an observation group (53 cases, 2 cases dropped off ) and a control group (53 cases, 3 cases dropped off ). The patients in the both groups were treated with medications for basic diseases and conventional acupuncture at Waiguan (TE 5), Shousanli (LI 10) and Jianyu (LI 15) on the affected side. In addition, the patients in the control group were treated with Bobath rehabilitation training, 20 minutes each time; on the basis of the control group, the patients in the observation group were treated with WANG Ju-yi's meridian diagnosis method to adjust the abnormal parts in meridians of the hand taiyin and hand yangming on the affected side, 20 minutes each time. Both groups were treated once a day, 5 times a week for 8 weeks. The scores of visual analogue scale (VAS), upper-limb Fugl-Meyer assessment (FMA) and Barthel index (BI) were recorded before and after treatment as well as 6 weeks after treatment (follow-up), and the clinical efficacy of the two groups was evaluated after treatment.
RESULTS:
Compared before treatment, the VAS scores were reduced and the scores of upper-limb FMA and BI were increased in the two groups after treatment and in the follow-up (P<0.05). The VAS score in the observation group was lower than that in the control group (P<0.05), and the scores of upper-limb FMA and BI in the observation group were higher than those of the control group (P<0.05). The total effective rate in the observation group was 82.4% (42/51), which was higher than 62.0% (31/50) in the control group (P<0.05).
CONCLUSION
WANG Ju-yi 's meridian diagnosis method combined with Bobath rehabilitation training could effectively treat post-stroke SHS typeⅠ, reduce pain symptoms and improve joint motor dysfunction, and improve the quality of life. Its curative effect is better than Bobath rehabilitation training alone.

Chlorophyll content,leaf mass to per area,net photosynthetic rate and bioactive ingredients of Asarum heterotropoides var. mandshuricum,a skiophyte grown in four levels of solar irradiance were measured and analyzed in order to investigate the response of photosynthetic capability to light irradiance and other environmental factors. It suggested that the leaf mass to per area of plant was greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in the decrease of leaf mass to per area at every phenological stage. At expanding leaf stage,the rate of Chla and Chlb was 3. 11 when A. heterotropoides var. mandshuricum grew in full light irradiance which is similar to the rate of heliophytes,however,the rate of Chla and Chlb was below to 3. 0 when they grew in shading environment. The content of Chla,Chlb and Chl( a+b) was the greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in its decreasing remarkably( P<0. 05). The rate of Chla and Chlb decreased but the content of Chla,Chlb and Chl( a+b) increased gradually with continued shading. The maximum value of photosynthetically active radiation appeared at 10: 00-12: 00 am in a day. The maximum value of net photosynthetic rate appeared at 8: 30-9: 00 am and the minimum value appeared at 14: 00-14: 30 pm at each phenological stage if plants grew in full sunlight. However,when plants grew in shading,the maximum value of net photosynthetic rate appeared at about 10: 30 am and the minimum value appeared at 12: 20-12: 50 pm at each phenological stage. At expanding leaf stage and flowering stage,the average of net photosynthetic rate of leaves in full sunlight was remarkably higher than those in shading and it decreased greatly with decreasing of irradiance gradually( P < 0. 05). However,at fruiting stage,the average of net photosynthetic rate of leaves in full sunlight was lower than those in 50% and 28% full sunlight but higher than those in 12% full sunlight. All photosynthetic diurnal variation parameters of plants measured in four kinds of different irradiance at three stages were used in correlation analysis. The results suggested that no significant correlation was observed between net photosynthetic rate and photosynthetically active radiation,and significant negative correlation was observed between net photosynthetic rate and environmental temperature as well as vapor pressure deficit expect for 12% full sunlight. Positive correlation was observed between net photosynthestic rate and relative humidity expect for 12% full sunlight. Significant positive correlation was observed between net photosynthetic rate and stomatal conductance in the four light treatments. Only,in 12% full sunlight,the net photosynthetic rate was significantly related to photosynthetically active radiation rather than related to environmental temperature,vapor pressure deficit and relative humidity. In each light treatment,a significant positive correlation was observed between environmental temperature and vapor pressure deficit,relative humidity as well as stomatal conductance. Volatile oil content was 1. 46%,2. 16%,1. 56%,1. 30% respectively. ethanol extracts was 23. 44%,22. 45%,22. 18%,21. 12% respectively. Asarinin content was 0. 281%,0. 291%,0. 279% and 0. 252% respectively. The characteristic components of Asarum volatile oil of plant in different light treatments did not change significantly among different groups.
