Objective To isolate and culture sweat gland epithelial cells in vitro,and to study the effects of acetylcholine (ACh) on intracellular flee calcium concentration ([Ca~(2+)]i) of cultured sweat gland epithelial cells.Methods Sweat glands epithelial cells were collected by enzymatic digestion.After ACh was added to the primary and first passage cells,[Ca~(2+)]i was examined using confocal laser scanning microscopy (CLSM) and the Ca~(2+) sensitive dye Fura 3/AM.Results The primary and first passage epithe- lial cells grew well.After ACh was added,opening of the calcium channel and significant [Ca~(2+)]i increase were observed when the primary and first passage cells were incubated with high concentration of calcium (2 mmol/L);no significant [Ca~(2+)]i increase was observed in those cultured without calcium.Conclusion Upon stimulation with ACh,calcium channels of cultured primary and first passage sweat gland epithelial cells would open,influx of extracellular Ca~(2+) occurred,which resulted in an increase of [Ca~(2+)]i.Extracellular bound calcium was therefore converted into intracellular free calcium.

Objective: The integrity of the corresponding dorsal root is important in the research of the effects of acupuncture Zusanli (ST 36) on gastric smooth muscle. Investigate the communicate channels of central control on the effect of acupuncture Zusanli (ST 36). Method: Selected 30 healthy adult SD rats and using veniua-glacial acid to made gastric mucosa ulcer model. Divided them into three groups, model group, cutting L1-S1group and transecting T10-T11group after the models have been made successfully, each group 10 rats. Implanted diameter in 0.2 mm Platinum Circle electrode into subserous of the ulcer place and recorded the myoelectricity activity of gastric smooth muscle before and after acupuncture Zusanli (ST 36). Acupuncture parameters, 2-100 Hz, lasting 20 mill. Results: Model group before acupuncture, (5.73±0.51) cycle per minitue (cpm), (2.28±0.57) mV; model group after acupuncture, (5.34±0.34) cpm, (1.06±0.13). Group that before cutting dorsal L4-S1, (5.65±0.26) cpm, (1.66±0.15) mV; group that after cutting dorsal L4-S1(5.40±0.23) cpm, (1.17±0.23), group that after cutting dorsal L4-S1and acupuncture, (5.26±0.18) cpm, (2.45±0.23). Group that before transecting dorsal T10-T11, (5.69±0.36) cpm, (1.91±0.25) mV, group that after transecting dorsal T10-T11, (4.98±0.53) cpm, (1.05±0.18) mV, group that after transecting dorsal T10-T11and acupuncture, (4.60±0.44) cpm, (2.52±0.38) mV. Conclusion: Acupunture Zusanli (ST 36) can inhibit the myoelectricity activity of gastric smooth muscle, cutting L4-S1 can strengthen the myoelectricity activity, but the effect of transect T10-T11 is better. So it can be said that the integrity of Dorsal root is important to the effect of acupuncture. The two-way regulation of Acupuncture has a close relationship with the higher centre above spinal cord.

Objective: To discovery the central mechanism of acupuncture Heart Meridian precondition myocardial ischemia in gene expression pattern, the authors applied gene chip tech to filter variably expressed genes in hypothalamus. Methods: Rats were seperated into normal, model, acupuncture Heart Meridian group and acup Lung Meridian group randomly. Acute myocardial ischemia rat model was made with ligation left anterior descending branch of the coronary artery. After model succeed, select hypothalamus seperately and mixed the same group together of 3 rats. Then applied Rats U230A genechip refered by Affymetrix Co. to compare the variations between these groups. Results: To compare with normal group, differential expression genes and expression sequence tags (ESTs) in model group were 73 with signal log ratio ≤ 1 and 92 with signal log ratio ≤-1 , mainly included ion channel, calcium/ calmodulin-dependent protein kinase Ⅱ inhibitor, antigen and so on. Similarly, compared with model group, differential expression genes and expression sequence tags (ESTs) were 190 with signal log ratio ≥ 1 and 34 with signal log ratio ≤-1 in acupuncture Heart Meridian group, mainly included 5-hydroxytryptamine receptor, cellular metabolism, fatty, immuno reaction, G-protein coupled receptors, ion transport, signal transductions and so on, while in acupucnture Lung Meridian, the number is 57 and 26 correspondly. Conclusion: There were exactly variations in hypothalamus mechanism that relate to acupuncture Heart and Lung Meridians.

Background and purpose:When the patients with nasopharyngeal carcinoma (NPC) receive radiotherapy, their thyroids are inevitably involved. As a result, thyroid damage occurs. This study aimed to explore the effects of intensity modulated radiation therapy (IMRT) on dynamics of thyroid blood flow in patients with NPC.Methods:A total number of 68 patients with NPC were enrolled in the study who received primary treatment of radical radiation and chemotherapy from Jul. 2012 to Oct. 2013. And the TMN stage was fromⅡ toⅣc according to UICC 2010. The treatment method consisted of 2 cycles of TPF induction treatment, concurrent radiation therapy (IMRT) with 2 cycles of DDP and 2 cycles of adjuvant therapy sequentially. Before radiotherapy, at the end of radiotherapy, 3 and 6 months after radiotherapy, serum free triiodothyronine (FT3), free thyroxin (FT4) and thyroid-stimulating hormone (TSH) concentrations of all cases were detected by electrochemiluminescence. The highest systolic velocity, mean velocity, minimum diastolic velocity, resistance index, and the value of all thyroid diameter lines were measured by type-B ultrasound.Results:All the patients were followed up for 6 months. Hypothyroidism: the incidence of immediate clinical hypothyroidism after radiotherapy was 5.9%; 3 months later, the incidence was 13.2%; and 6 months later, the incidence was 26.5%. The difference in volume change between before radiotherapy and at the end of radiotherapy had no statistical signiifcance (P>0.05). The difference in volume change between 3 and 6 months after radiotherapy had statistical signiifcance (P<0.05). The difference in FT3, FT4 and FSH between the end of radiotherapy and before radiotherapy had no statistical signiifcance, while there was statistically signiifcant difference between at the end of radiotherapy and 3 months after radiotherapy. The thyroid volume correlated with the average dose at the end of radiotherapy, 3 and 6 months after radiotherapy as shown by the single factor correlation analysis (P<0.05). The results of sinlge factor correlation analysis also showed that the occurrence of hypothyroidism correlated with thyroid dose-volume parameter V40 at the end of radiotherapy (P<0.05). The correlation between hypothyroidism and the average dose on thyroid 6 months after radiotherapy was demonstrated by independentt test (P<0.05). Hypothyroidism had no correlation with thyroid artery systolic maximum velocity and resistance index at the end of radiotherapy, 3 and 6 months after radiotherapy (P>0.05).Conclusion:The incidence of hypothyroidism may increase with time after radiotherapy. The volume may decrease with the increased dose of radiotherapy and the follow-up time. The patients with NPC after radiotherapy should be tested for thyroid lesions routinely. The thyroid dose-volume parameter V40 may be a predictor for acute radioactive thyroid lesions. The study did not reveal temporarily that hypothyroidism was associated with thyroid ultrasound blood lfow velocity.
