OBJECTIVETo observe the effects of moxibustion with different temperatures on cholesterol and skin around "Shenque" (CV 8) in mice with acute hyperlipidemia, and to explore the correlation between moxibustion effect and transient receptor potential vanilloid 1 (TRPV1).

METHODSEight mice among 32 mice of C57BL/6J wild type (WT) were selected into a blank group, and the remaining 24 mice were made into the acute hyperlipidemia model by injection of egg yolk. After model establishment, the mice were randomly divided into a model group, a 38 °C moxibustion group and a 46 °C moxibustion group, 8 mice in each group. The temperature was (38 ± 1) °C in the 38 °C moxibustion group and (46 ± 1) °C in the 46 °C moxibustion group. "Shenque" (CV 8) and "Zusanli" (ST 36) were selected in the two groups; moxibustion was given for 10 min per time, once a day for 2 times. Mice in the blank group and model group were treated with immobilization and moxibustion was not given. After treatment, the level of serum cholesterol was tested by oxidase method; the morphology of skin around "Shenque" (CV 8) was observed by HE staining; the expression of TRPV1 in skin was measured by immunohistochemistry.

RESULTS(1) Compared with the blank group, the level of serum cholesterol was increased in the model group (P < 0.001); compared with the model group, the level of serum cholesterol was reduced in the 46 °C moxibustion group (P < 0.001); compared with the 38 °C moxibustion group, the level of serum cholesterol was reduced in the 46 °C moxibustion group (P < 0.01). (2) There was slight change of morphology and structure in skin tissue in the 38 °C moxibustion group, while obvious change was observed in the 46 °C moxibustion group, indicating specific change. (3) The difference of the expression of TRPV1 in skin was significantly different between 46 °C moxibustion group and blank group, model group (both P < 0.01); it was also different from the 38 °C moxibustion group (P < 0.05).

CONCLUSIONMoxibustion temperature is one of the important factors affecting the cholesterol and acupoint skin. The effects of moxibustion are related to TRPV1.

Objective To compare the clinical effects of palpation, ultrasound and electromyography (EMG) guided injection of botuli-num toxin type A (BTX-A) on spastic equinovarus in stroke patients. Methods Stroke patients with equinovarus were randomly assigned to palpation-guided group (n=19), ultrasound-guided group (n=21) and EMG-guided group (n=19). All of the patients received injection of BTX-A 300 U in gastrocnemius, soleus and tibialis posterior, guided in their own ways. They were measured with modified Ashworth Scale (MAS), Physician Rating Scale (PRS), speed of gait, passive range of motion (PROM) of ankle dorsiflexion and eversion before and 2 weeks, 4 weeks, 8 weeks, and 12 weeks after injection. Results Compared with the baseline, all the indexes significantly improved after in-jection in all the groups (P<0.05). Compared with the EMG-guided group, the ultrasound-guided group improved significantly MAS at 4 weeks, PROM of ankle eversion at 4 and 12 weeks (P=0.046, P=0.008, P=0.038). Compared with the palpation-guided group, the ultra-sound-guided group improved significantly in MAS (P=0.015), PRS (P=0.01), PROM of ankle dorsiflexion and eversion (P=0.003, P=0.011) at 4 weeks, in MAS (P=0.002) and PROM of ankle dorsiflexion (P=0.022) at 8 weeks, in MAS (P=0.011) and PROM of ankle ever-sion (P=0.018) at 12 weeks. Compared with the palpation-guided group, the EMG-guided group improved significantly in PRS at 4weeks, PROM of ankle dorsiflexion at 4 and 8 weeks (P=0.048, P=0.08, P=0.026). There was no significantly difference in the variations with the time among 3 groups. Conclusion The correction of equinovarus in stroke patients can be obtained by BTX-A injection with any type of guidance technique. Ultrasound-guided technique is considered a valid alternative, which has a slight advantage over EMG-guided tech-nique. Both the EMG-and ultrasound-guided techniques obtained superior results to palpation-guided technique.

OBJECTIVETo study the correlation of 1-deoxynojirimycin (DNJ) between Taxilli Herba parasitized in mulberry and its host-plants.

METHODThe contents of DNJ of Taxilli Herba parasitized in mulberry and non-mulberry were determined by RP-HPLC. DNJ was extracted with 0.05 mol x L(-1) HCl, and then detected by fluorescence detector after derivatized with FMOC-Cl at pH 8.0 with borate buffer. The separation was performed on an Agilent C18 (4.6 mm x 250 mm, 5 microm) column with a mobile phase of acetonitrile-0.1% aqueous acetic acid (51: 49) at a flow rate of 1.0 mL x min(-1). The wavelength of fluorescence detector was operated at lambda(EX) = 254 nm and lambda(EM) = 322 nm.

RESULTThe linear range of DNJ was 3.72-37.2 mg x L(-1) (r = 0.999 9). The average recovery was 96.42%. The contents of DNJ in mulberry and Taxilli Herba parasitized in mulberry were 1.39-10.16 mg x g(-1) and 0.46-2.72 mg x g(-1), respectively. However, the contents of DNJ could not be detected in Taxilli Herba parasitized in non mulberry and its host-plants.

CONCLUSIONAs the characteristic constituent of mulberry, DNJ was accumulated in Taxilli Herba This method can be applied to the quality control of Taxilli Herba from mulberry.

Objective To establish a quality traceability evaluation method for the whole honeysuckle oral solution process by identifying and screening its anti-inflammatory quality markers.Methods UPLC/-TOF-MS was used to analyze the iridoids and phenolic acids in oral solution,and the correlations were constructed by molecular network technology.The HPLC fingerprints of multiple batches of oral solution were established,and similarity analyses were performed to identify key pharmacodynamic molecules.The key anti-inflammatory quality markers were confirmed by the NF-κB dual luciferase assay system.Further,the quantification of 12 quality markers of iridoids and phenolic acids in oral solution was established separately based on the dual-wavelength HPLC technique.The quality of the oral solution was evaluated by examining the extraction and transfer rate of quality markers during the processing of raw materials and preparations and thermal stability.Results A total of 9 iridoids and 6 phenolic acids were identified in the oral solution,and the possible conversion relationships between their components were depicted.Fingerprint analysis of 11 batches of oral liquids showed that the composition of their main peaks was the same,with a similarity of more than 90%.Among them,6 iridoids(loganic acid,secologanoside,secologanic acid,sweroside,secoxyloganin,secologanin)and 6 phenolic acids(neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,isochlorogenic B,isochlorogenic A,isochlorogenic C)exhibited NF-κB inhibitory activity,which were the main pharmacological components and could be used as quality markers.The traceability of the above 12 quality markers was investigated in a multi-batch process based on the dual-wavelength HPLC method.The thermal stability studies of the raw materials revealed that the contents of their total iridoids and phenolic acids remained stable.Still,some of them would be transformed between components.The production process of the oral solution was stable,and the transfer rates of the iridoids and phenolic acids during the extraction,concentration and preparation were over 76%and 63%,respectively.Conclusion The method is stable,reliable,easy to operate and can evaluate the full honeysuckle oral solution process,which provides an effective means for the quality control of honeysuckle herbs and preparations.

Dental caries detector is a kind of diagnostic tool specifically designed for dental professionals to detect and monitor the early occurrence and development of dental caries. They are widely used in the clinic because of their advantages of rapid detection, flexible applications, ease of carrying, intuitive detection results and lack of pain for the patient. However, due to the different types and principles of the instruments produced by various instrument manufacturers, the clinical application range, sensitivity and specificity of test results also show significant differences. In terms of the current clinical application effects, although the DIAGNOdent caries detector has the widest range of clinical use, the accuracy of its detection results needs to be improved because it is affected by factors such as pigments and dental materials. The Canary System caries detector can effectively avoid the interference of the above factors, but its classification of the degree of caries is not clear. The DIAGNOcam caries detector can effectively detect early caries, but it has low reliability for occlusal caries detection. The existing dental caries detectors on the market can be used only as clinical auxiliary tools, and the accuracy of the detection results and comprehensiveness of the detection range need further improvement. With the application of the new multispectral near-infrared scanning fiber endoscope (NIR-SFE) and high-frequency ultrasound imaging (HFUS) in the detection of dental caries, a more efficient and accurate diagnosis of dental caries is possible in the future. To this end, we still need to continue exploring new technology to help clinicians complete the early diagnosis and treatment of dental caries to improve the quality of life of their patients.

OBJECTIVETo evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on the quality of recovery during the early period after laparoscopic cholecystectomy and the dosage of anesthetic and analgesic.

METHODSOne hundred patients who received laparoscopic cholecystectomy with gradeⅠand Ⅱ of American Society of Anesthesiologists (ASA) criteria were randomly assigned into an observation group and a control group according to random number table, 50 cases in each group. The patients in the two groups were treated with conventional endotracheal intubation anesthesia, anesthesia induction and maintenance. The patients in the observation group were treated with TEAS (2 Hz/100 Hz, 8 to 12 mA) at bilateral Hegu (LI 4) and Neiguan (PC 6), as well as Zusanli (ST 36) and the non-acupoint 2 outboard from Zusanli (ST 36) from 30 min before anesthesia induction to the end of operation. The patients in the control group were applied by stimulation electrode in the corresponding points without electrical stimulation. The dosage of intraoperative remifentanil and the analgesic dosage of dezocine for postoperation were recorded. The recovery time, extubation time, the changes of heart rate (HR) and mean arterial pressure (MAP) during extubation were recorded. The quality of recovery was assessed by the quality of recovery-40 questionnaire (QoR-40) 1 day before surgery (T)，and 4 h (T), 8 h (T), 24 h (T), 48 h (T) after surgery. The patient's cognitive function was assessed by mini-mental state examination (MMSE) scale at the 5 time points. The incidences of postoperative nausea and vomiting were recorded at T through T.

RESULTSThe dosages of intraoperative remifentanil and dezocine in the observation group were less than those in the control group; the recovery time and extubation time were shorter than those in the control group; the HR of extubation was lower than that in the control group (all <0.05). There was no statistic difference about MAP between the two groups (>0.05). Compared with T, the total scores of QoR-40 decreased in the two groups at T, T, T (all <0.05), and the total scores in the observation group were higher than those in the control group (all <0.05). The emotional state, physical comfort, psychological support, self-care ability, pain scores at T in the observation group and at T, T, T in the control group were lower than those at T (all <0.05). The emotional state, physical comfort, psychological support, self-care ability, pain scores in the observation group were higher than those in the control group at T, T, T (all <0.05). Compared with T, the MMSE scores in the two groups decreased at T and T (all <0.05). At T, T, T, the MMSE scores in the observation group were higher than those in the control group (all <0.05). At T and T, the incidence rates of nausea and vomiting were 22.0% (11/50), 12.0% (6/50) respectively in the observation group, which were lower than 32.0% (16/50) and 24.0% (12/50) in the control group (both <0.05). At T and T, the incidence rates of nausea and vomiting were 6.0% (3/50), 2.0% (1/50) respectively in the observation group, which were not significantly different from 8.0% (4/50) and 4.0% (2/50) in the control group (both >0.05).

CONCLUSIONTEAS can improve the quality of recovery during the early period after laparoscopic cholecystectomy and reduce the dosage of anesthetic and analgesic.
