Out of the 20 channels in the channel and collateral system, only 5 enter the brain, with unclear circulation pathway in the brain. Electrophysiologic and imaging studies indicate that the signal induced by acupuncture at acupoints can enter the brain no matter whether the channel connecting the acupoint enters the brain. Therefore, the authors put forward the hypothesis of "all the 12 channels enter the brain", i.e., the hypothesis of "channels and collaterals in brain". In the theory system of channels, less channels enter the brain with unclear circulation pathway. This possibly is related with that sensation is main way for descovery of channels. In future, we should adopt modern scientific and technical ways and strengthen the study on circulation of channels in the brain, so as to perfect the channel theory.

OBJECTIVETo explore the clinical significance of serum matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1), and monocyte CD147 in rheumatoid arthritis (RA) patients of damp-heat Bi-syndrome (DHBS) and of cold-damp Bi-syndrome (CDBS).
METHODSThe clinical data of 22 patients from inpatients and outpatients with RA were collected, and their peripheral blood was withdrawal. The disease activity scores [DAS28(4)] were assessed. The serum levels of MMP-3 and TIMP-1 were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA). The mean fluorescence intensity (MFI) and the expression percentage of CD147 on CD14+ monocytes were detected by flow cytometry. The difference of each index between RA patients of DHBS and RA patients of CDBS was analyzed.
RESULTSThe level of serum MMP-3 and the MFI of CD147 on the monocyte surface were obviously higher in RA patients of DHBS than in those of CDBS and the normal control group (P < 0.05). The concentration of serum TIMP-1 was obviously higher in RA patients of DHBS than in those of the normal control group (P < 0.05), while there was no statistical difference between the two syndrome types. The percentage of CD147 expression was obviously lower in DHBS than in those of CDBS and the normal control group (P < 0.05).
CONCLUSIONSIncreased serum MMP-3 level of RA patients of DHBS might result in destroy of joint cartilages and sclerotin. The significant increase of MFI and decreased expression percentage of monocyte CD147 might be the results of increased disease activity of RA and monocyte migration to the synovial membrane tissue.

OBJECTIVETo investigate the value of five-repetition sit-to-stand test (5STS) in clinical evaluation of elderly patients with chronic obstructive pulmonary disease (COPD).
METHODSFifty-one patients with COPD and 20 healthy individuals were enrolled in this study. All the participants underwent 5STS, pulmonary function examination, and 6 min walking test (6MWT) and were evaluated for severity of dyspnea (by mMRC) and BODE index during the tests.
RESULTSAll the participants completed 5STS test with a good reproducibility of the time used for 3 sessions of the test (P<0.001). The mean time used by COPD patients for 5STS was significantly longer than that by healthy individuals (12.93±3.11s vs 0.72±0.71 s, P=0.002). The results of 5STS showed a significant negative correlation with those of 6MWT in the case group and control group with correlation coefficients of -0.611 and -0.682, respectively. The results of 5STS were negatively correlated with FEV1%Pre and body mass index (P<0.05) but positively with mMRC and BODE index in COPD patients (P<0.05).
CONCLUSION5STS is a simple and reproducible test to evaluate the patients' exercise capacity and the severity of COPD, and is well correlated with the current methods for clinical evaluation of COPD.

OBJECTIVESTo summarize the experience of surgical intervention for hepatocellular carcinoma (HCC) with bile duct thrombi (BDT), and to evaluate the influence on prognosis.
METHODSFrom 1994 to 2002, 15 patients with HCC and BDT who underwent surgical intervention were retrospectively analyzed.
RESULTSThe operative procedures included hepatectomy with removal of BDT (n = 7), hepatectomy combined with extrahepatic bile duct resection (n = 4), thrombectomy through choledochotomy (n = 3), and piggy-back orthotopic liver transplantation (n = 1). The 1- and 3-year survival rates were 73.3% and 40%, respectively. Two patients survived over 5 year. The survival rate of patients with portal vein invasion was significantly lower than that of patients without portal vein invasion (P < 0.05).
CONCLUSIONSSurgical intervention was effective for patients with HCC and BDT. Operation after recurrence can prolong the survival time. Liver transplantation is a new operative procedure worthy of study.

BACKGROUNDThe decrease of glomerular filtration rate has been theoretically supposed to be the result of low perfusion in renal artery stenosis (RAS). But the gap between artery stenosis and the glomerular filtration ability is still unclear.
METHODSPatients with selective renal artery angiogram were divided by the degree of renal artery narrowing, level of estimated glomerular filtration rate (eGFR), respectively. The different levels of eGFR, renal microcirculation markers, and RAS severity were compared with each other, to determine the relationships among them.
RESULTSA total of 215 consecutive patients were enrolled in the prospective cohort study. Concentrations of microcirculation markers had no significant difference between RAS group (RAS ≥ 50%) and no RAS group (RAS < 50%) or did not change correspondingly to RAS severity. The value of eGFR in RAS group was lower than that in the no RAS group, but it did not decline parallel to the progressive severity of RAS. The microcirculation markers presented integral difference if grouped by different eGFR level with negative tendency, especially that plasma cystatin C (cysC) and urinary microalbumin to creatinine ratio (mACR) increased with the deterioration of eGFR, with strong (r = -0.713, P < 0.001) and moderate (r = -0.580, P < 0.001) correlations. In the subgroup analysis of severe RAS (RAS ≥ 80%), the levels of plasma cysC and urinary mACR demonstrated stronger negative associations with eGFR, (r = -0.827, P < 0.001) and (r = -0.672, P < 0.001) correlations, respectively.
CONCLUSIONSSeverity of RAS could not accurately predict the value of eGFR, whereas microcirculation impairment may substantially contribute to the glomerular filtration loss in patients with RAS.

OBJECTIVETo explore distribution of the Liver and Lung Channels in the brain so as to provide imaging basis for construction of channel theory in the brain.
METHODSSixty healthy student volunteers were randomly divided into a Liver Channel group (I) and a Lung Channel group (II), and the each group was further divided into five subgroups with 6 volunteers in each subgroup, based on five-shu-point principles which, were Dadun (LR 1, I 1), Xingjian (LR 2, I 2), Taichong (LR 3, I 3), Zhongfeng (LR 4, I 4), Ququan (LR 8, I 5), Shaoshang (LU 11, II 1), Yuji (LU 10, II 2), Taiyuan (LU 9, II 3), Jingqu (LU 8, II 4), and Chize (LU 5, II 5), respectively. In order to observe the brain activating patterns during acupuncture at the different acupoints, functional magnetic resonance imaging (fMRI) technique was adopted. All image data were then analyzed with SPM 2 software. The statistical parameter gram was composed of the pixel P < 0.01, and anatomic location was made according to Talairach coordinate, attaining experimentally activated areas, and the commonly activated area of five-shu-point of each channel was considered as the brain distribution of the Liver and Lung Channels.
RESULTSThe common areas activated by the five-shu-points of the Liver Channel were homolateral Brodmann area (BA) 34, BA 47, red nucleus, contralateral BA 19, BA 30, BA 39, the superior parietal lobule, cerebellum decline, and bilateral BA 3 and culmen. The common areas activated by the five-shu-points of the Lung Channels included homolateral BA 2, BA 18, BA 35, and contralateral BA 9 and substania nigra.
CONCLUSIONThere are relatively specific corresponding brain areas for the Liver and Lung Channels, indicating that there is possible relatively specific connection between channels and the brain.

Acupuncture manipulations on Fengchi (GB 20) of famous doctors were taken through force feedback device, then the data was input into a digitized virtual human. Virtual Fengchi (GB 20) acupuncture force feedback simulation system was built through the virtual reality technology to achieve one-to-one high simulative manipulation effect for acupuncture students. The interaction force of the needle body and human tissues was analyzed during the acupuncture process on the 3D digital human integrated with information of Fengchi (GB 20) according to the physical characteristics of the tissues under this point. The mechanical model which is used to imitate the stress received by the body of the needle was established, and transmitted truly to the operator by the force feedback device. Thus, Fengchi (GB 20) virtual acupuncture force feedback simulation was preliminary established, and the sense of touch could be reproduced lively on the visualized virtual acupuncture human. It is held that Fengchi (GB 20) acupuncture force feedback research is a preliminary exploration for virtual acupuncture that integrated with the information of visual, tactile and force feedback. And it also provided a dynamic one-to-one simulation approach for acupuncture teaching.

Aim To study the therapeutic effect of Balanophora polysaccharide(BPS)on gastric ulcer(GU)induced by acetic acid in rats and to investigateits mechanisms. Methods Sixty male SD rats were randomly divided into sham-operated group, GU model group, omeprazole positive group(3.6 mg·kg-1), and low, medium and high dose of BPS treatment groups(100, 200 and 400 mg·kg-1). The GU model group was prepared by acetic acid cautery method, and the morphology and pathological changes of ulcers were observed by visual observation combined with HE staining, and the ulcer area and inhibition rate were measured and calculated; superoxide dismutase(SOD)activity, malondialdehyde(MDA)content and glutathione peroxidase(GSH-PX)activity were measured by enzymatic assay; tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)content were detected by ELISA. The expression levels of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)were measured by immunohistochemistry staining and Western blot. Results Compared with the sham-operated group, obvious ulcer damage was seen in the model group. Compared with the model group, the BPS-treated group showed a significant reduction in ulcer area, an increase in SOD and GSH-PX activity and EGF and EGFR expression levels, and a significant decrease in MDA, TNF-α and IL-6 content. Conclusions BPS has a therapeutic effect on GU in rats, and its mechanism may be related to the inhibition of oxidative stress, suppression of inflammatory stimuli and promotion of regenerative repair of gastric mucosa.

Objective: To evaluate the safety and efficacy of transcatheter aortic valve replacement (TAVR) with domestic prostheses in patients with severely stenotic bicuspid aortic valve (BAV). Methods: This study was a prospective single-center non-randomized controlled study. Patients with symptomatic severe aortic stenosis (AS), who underwent TAVR with domestic prostheses at the First Affiliated Hospital of Air Force Medical University from January 2016 to April 2020 were consecutively included in our study. Patients were divided into BAV group and tricuspid aortic valve (TAV) group according to the aortic valve morphology. Baseline characteristics, procedural outcomes were compared between the two groups, and the primary endpoint was one-month all-cause mortality. Results: A total of 100 patients aged (69.8±8.9) years were enrolled, including 71 (71%) males. There were 51 cases in BAV group and 49 cases in TAV group. Compared with TAV group, patient in the BAV group was younger ((67.1±8.6) years vs. (72.7±8.4) years, P=0.002) and had larger ascending aortic diameter at proximal part ((39.7±5.7) mm vs. (36.0±4.2) mm, P<0.001), lower Society of Thoracic Surgeons-Predicted Risk of Mortality (STS-PROM) score (3.1 (1.9, 5.4) % vs. 5.9 (2.6, 12.3) %, P=0.002). In BAV group and TAV group, the incidence of 2nd prosthesis implantation was 15.7% (8/51) and 18.4% (9/49) (P=0.721), the incidence of moderate or severe paravalvular regurgitation was 2.0% (1/51) and 0 (P=1.000), the rate of device success was 82.4% (42/51) and 81.6% (40/49) (P=0.925), respectively. One-month all-cause mortality was 2.0% (1/51) and 10.2% (5/49) (P=0.108), respectively. Echocardiography showed that postprocedural mean pressure gradient (PGmean) was higher in the BAV group (13.0 (10.0, 16.0) mmHg vs. 9.0 (7.0, 14.0) mmHg, P=0.003) (1 mmHg=0.133 kPa), but the PGmean decrease post procedure as compared with that before TAVR was similar between the two groups ((36.7±16.6) mmHg vs. (36.2±17.5) mmHg, P=0.893). Conclusion: Favorable safety and efficacy are evidenced in patients with severely stenotic BAV undergoing TAVR with domestic prostheses.
