OBJECTIVE: To explore the characteristics and rules of the locations of acupoints selected in weight loss after syndrome differentiation of acupuncture and moxibustion, and provide quantitative evidence for the location specificity of acupoint selection in weight loss. METHODS: Clinical research articles on acupoint selection based on syndrome differentiation of acupuncture and moxibustion in weight loss were retrieved in China National Knowledge Infrastructure (CNKI), from the inception to September 20th, 2024, and the data about acupoints and differentiated syndromes were extracted. Based on graph theory, the acupoint-syndrome network was established and its topological parameters such as node degree, value of betweenness centrality, description length and number of community were calculated. RESULTS: ①The description length of the limbs was 4 255.592, and that of the trunk was 3 274.312. The information contained in the acupoint-syndrome network for the acupoints on the limbs was greater than that for those on the trunk. ②The value of betweenness centrality and node degree showed a nonlinear relationship, with R²of 0.812 1 for the trunk and 0.321 8 for the limbs. The values of betweenness centrality for the acupoints on the trunk were uniformly distributed, and the difference among these values was much smaller than that for the acupoints on the limbs. It suggested that the distance from each trunk acupoint to network center was similar, and the importance among these acupoints to network was similar, while the importance among acupoints located on the limbs was different significantly. ③The frequency proportion of acupoints on the trunk showed uniform distribution among different syndromes, while that of some acupoints located on the limbs such as Taichong (LR3), Neiting (ST44) and Taixi (KI3) presented a correlation with the syndromes. CONCLUSION In weight loss with acupuncture and moxibustion, the correlation between the limb acupoints and syndromes is more diverse and specific than that between the trunk acupoints and syndromes. The differences in acupoint selection for simple obesity treated with acupuncture and moxibustion are mostly reflected in the acupoints on the four limbs rather than those on the trunk. It provides an approach to acupoint selection for "local weight loss" and "general regulation" in treatment with acupuncture and moxibustion.

OBJECTIVETo explore the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative analgesia of ureteroscopic holmium laser lithotripsy.

METHODSOne hundred and twenty adult patients, American Association of Anesthesiologists (ASA) Class Ⅰ or Ⅱ, scheduled to ureteroscopic holmium laser lithotripsy, were randomly assigned into an observation group and a control group, 60 cases in each one. The patients in the observation group were treated with TEAS for postoperative analgesia. TEAS was implemented at bilateral Shenshu (BL 23) and Yinlingquan (SP 9) at the time of back ward and postoperative 4 h, 8 h, 12 h. TEAS at 7:00, 11:00 and 15:00 at the above acupoints were used on the second and third days; while placebo (twice a day, 100 mg a time) was used. Tramadol hydrochloride tablets for postoperative analgesia were applied in the contnol group, twice a day, 100 mg a time, and electrode sheets without stimulation were put on Shenshu (BL 23) and Yinlingquan (SP 9). When analgesia was insufficient with the score of visual analogue scale (VAS)≥3, the patients were treated with tramadol tablets for remedy analgesia. The VAS score, the concentrations of serotonin (5-HT) and substance P (SP) in 3 mL venous blood at the time of back ward (T), postoperative 4 h (T), 12 h (T), 24 h (T), and 48 h (T) were detected respectively. The total amount of medication for remedy analgesia and the incidence of adverse reactions, such as nausea and vomiting within postoperative 48 h were compared between the two groups.

RESULTSThe VAS scores at T through T were lower than those at T in the two groups (all <0.05). Compared with the control group, the VAS scores at T through T in the observation group were lower (all <0.05). The total dose of remedy analgesic medicine within 48 h after operation in the observation group was lower than that in the control group (<0.05). Compared with the control group, the concentrations of 5-HT at T, T, T and SP at T through T were lower (all <0.05). The numbers of constipation, nausea and vomiting in the observation group were less than those in the control group (both <0.05).

CONCLUSIONTEAS can relieve the pain and reduce the total amount of analgesic medicine, the levels of substance causing pain and the incidence of adverse reactions after ureteroscopic holmium laser lithotripsy.

OBJECTIVE:To prepare Carbinoxamine maleate sustained-release suspension,and evaluate its quality. METH-ODS:Using carbinoxamine maleate as raw material,drug-loaded resin was prepared by cation exchange resin;surface coating method was used to finally prepare sustained-release suspension,using Eudragit RS100 as sustained-release coating material to pre-pare sustained-release microparticles. HPLC was conducted to determine the content of carbinoxamine maleate,release degree of original preparations and self-made suspensions was compared,drug-loading capacity was calculated. RESULTS:The drug amount in preparing drug-loaded resin was 2%,reaction temperature was 25 ℃,and reaction time was 4 h;the drug-loading capacity in surface coating was 35%,amount of coating material was 10%,and reaction temperature was 40 ℃. The drug-loading capacities of sustained particles before and after coating were 35.23%,32.72%,respectively;the yield was 96.82%. The carbinoxamine ma-leate in prepared sustained-release suspension accounted for 98.76% of the labeled amount;release degree in 10 h reached about 80%,f2 was 65.73. CONCLUSIONS:Carbinoxamine maleate sustained-release suspension is prepared successfully,and its release is similar to the original preparation.

Objective The aim of this study was to investigate the differences of the cell ultrastucture of normal mouse hatched blastocysts and their dormant ones cultured in vitro after freezing-thawing, and to explore whether the dor-mant embryos have a better anti-freezing shock property than the normal hatched mouse embryos .Methods By transmis-sion electron microscopy , the ultrastructure of these two types of mouse embryos was observed and analyzed .Results By comparative analysis of their ultrastructure , the results showed that the dormant embryos before freezing are being austerity and with lower energy metabolism at a ‘ground state ’ .After freezing-thawing and culture , their cellular structure seemed to be similar to that of the normal embryos cultured in vitro before freezing.However, after freezing-thawing and culture, the number of mitochondria decreased , the nuclei were loose , and their heterochromatin also increased .Conclusions From the ultrastructural observation , compared with the normal mouse hatched embryos , the cellular state of dormant mouse em-bryos after freezing-thawing is more favorable for material storage and energy metabolism , thus, indicating that they have a better anti-freezing property than normal hatched embryos .
