Objective To investigate the clinical efficacy of point Neiguan thumbtack needles in preventing and treating gastroscopy-induced nausea and vomiting.Methods Two hundred patients meeting the inclusion criteria were randomly allocated to treatment and control groups, 100 cases each. Before gastroscopy, both groups took lidocaine mucilage and the treatment group received point Neiguan thumbtack needle therapy additionally. Nausea and vomiting were observed in both groups of patients during gastroscopy.Results There were statistically significant post-treatment differences in nausea and vomiting severity and patients’ satisfaction between the two groups (P<0.05).Conclusions Point Neiguan thumbtack needle therapy can relieve gastroscopy-induced nausea and vomiting and raise patients’ satisfaction.

Extracorporeal membrane oxygenation (ECMO) is a novel mechanical system that provides respiratory and/or hemodynamic support to patients with severe respiratory or cardiac failure.These patients generally develop a state of increased metabolic activity accompanied by elevated catabolism of protein and negative nitrogen balance.Moreover,provision of adequate nutritional therapy is hard to achieve due to various factors.Nutrition support for these patients is hence a critical issue.This article provides a brief overview of the current literature regarding nutritional support during ECMO in adult patients,as no current guidelines address this issue.

A total of 17 cases with pelvic limb hyperhidrosis were selected for lumbar sympathetic nerve modulation.The puncture of lumbar sympathetic nerve was guided by computed tomography (CT) through the gap of L2-3 until the needle tip reached the lateral of the second or third lumbar vertebra body and outside of psoas major.A mixture of 1％ lidocaine 3 ml and 30％ Iohexol injection 0.3 ml was injected.If the diffusion of lidocaine was observed between lumbar vertebra body and psoas major.After 15 min,5 ml of absolute alcohol was injected to modulate the lumbar sympathetic nerve.After 5 min,oximetry-derived perfusion index of toe and sole temperature increased (5.9 ± 1.4) folds and (4.16± 0.89) ℃ on average respectively.Pelvic limb hyperhidrosis was all cured within 6 months and one case recurred after a year.There were no occurrences of complications.Lumbar sympathetic nerve modulation guided by CT may be used for treating female pelvic limbs hyperhidrosis.

BACKGROUND:Nano-calcium titanate, prepared with different modifiers, have properties of good osteogenesis, bone conductibility and biocompatibility.
OBJECTIVE:To observe the influence of nano-calcium titanate materials on the proliferation and differentiation of osteoblasts.
METHODS:Nano-calcium titanate was prepared with modifiers such as polyethylene glycol, acetyl trim ethyl ammonium bromide and sodium citrate. Meanwhile, nano-calcium titanate without modifier was prepared. Al the four kinds of nano-calcium titanate materials were used to prepare nano-calcium titanate extracts under the concentration of 0.1, 1.0, 10 g/L, respectively. The proliferation of osteoblasts was observed through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and alkaline phosphatase activity of osteoblasts was observed. Osteoblasts cultured in normal condition served as contrast.
RESULTS AND CONCLUSION:The proliferation of osteoblasts cultured in the calcium titanate extracts prepared with polyethylene glycol, acetyl trim ethyl ammonium bromide and sodium citrate and without modifier was obviously improved under the concentration of 1.0 and 10 g/L. Absorbance value of the cells cultured in the above-mentioned four kinds of calcium titanate extracts 1.0 and 10 g/L) for 3, 6, 9 days exceeded the contrast (P<0.05, P<0.01), as wel as the alkaline phosphatase activity (P<0.05, P<0.01). Calcium titanate prepared with polyethylene glycol, acetyl trim ethyl ammonium bromide and sodium citrate and without modifier has no cytotoxicity effect on osteoblasts, and can promote the proliferation and differentiation of osteoblasts.

Objective To observe the infiuence of recombinant human thyroid stimulating hormone(rhTSH)-aided 131I treatment for patients with differentiated thyroid carcinoma (DTC)and its efficacy on thyroid hormone level.Methods 20 cases with DTC admitted from Nov.2010 to Jun.2014 were divided into 2 groups.11 cases received rhTSH-aided 131I treatment (rhTSH-aided group)and the other 9 cases received 131I treatment after thyroid hormone withdrawal (THs withdrawal group).The influence of the 2 treatment methods on the serum TSH,FT3,FT4,Tg was evaluated,and the therapeutic effects were assessed according to 131I whole body scintigraphy (WBS)and Tg-negative rate.Results The serum TSH was significantly higher in rhTSH-aided group than that before treatment(t=27.70,P＜ 0.001)and in THs withdrawal group (t=7.18,P＜0.001).TSH levels of all patients were＞30 mU/L.WBS displayed that the thyroid remnant clearance rate was 72.73％(8 cases)nd 66.67％(6 cases)respectively in rhTSH-aided group and THs with-drawal group and there was no statistical difference between the 2 groups(x2=0.178,0.673).Conclusion The rhTsH treatment can help to accomplish the preparation of 131I treatment for DTC and acquire satisfactory ablation efficacy.

We designed a locator for puncture under CT examination.Thirty-three patients of both sexesaged 16-76 yr weighing 46-80 kg undergoing bilateral thoracic or lumber sympathetic nerve block under CT examination were enrolled in this study.One side was punctured under the guidance of the locator,while the other side was punctured by conventional technique.The time consumed during puncture,CT scan adjusting time,the deviation of the needle from the targets and the incidence of puncture complications were recorded.The results showed that compared with the conventional technique,with the locator the time consumed during puncture was significantly shorter,the number of attempts and the deviation of the needle from the target were significantly reduced.The procedure was successfully performed on both side in all patients without serious complications such as hemothorax and pneumothorax.

OBJECTIVETo explore the clinical effects of acupressure at Neiguan (PC 6) combined with press needles for prevention of gastroscopy-induced nausea and vomiting.

METHODSOne hundred and twenty patients who were scheduled to gastroscopy for the first time were randomly assigned into an acupressure group and a combined treatment group, 60 cases in each one.The patients in the two groups were treated with acupressure at Neiguan (PC 6) 15 min before gastroscopy; moreover, the patients in the combined treatment group were additionally treated with press needles at Neiguan (PC 6) until the end of gastroscopy. The time of gastroscopy-induced nausea and vomiting, VAS-based nausea and vomiting scale and the state-trait anxiety inventory were compared between the two groups.

RESULTSThe time of gastroscopy-induced nausea and vomiting in the combined treatment group was lower than that in the acupressure group (<0.05); the score of VAS-based nausea and vomiting scale in the combined treatment group was lower than that in the acupressure group (<0.05); the state-trait anxiety inventory was not significantly different between the two groups, before and after gastroscopy (all>0.05).

CONCLUSIONSAcupressure at Neiguan (PC 6) combined with press needles can relieve gastroscopy-induced nausea and vomiting without increasing anxiety.

Objective:To investigate the effectiveness and safety of soothing moisturizing repair cream on acne depressed scar exfoliative fractional laser wound repair.Methods:From October 2018 to June 2020, the Department of Dermatology, Qingdao Haici Hospital Affiliated to Qingdao University took 33 patients with acne depressed scars as the research object, including 8 males and 25 females, aged from 20 to 36 years (29.6±8.6) years. The left and right face comparison method was adopted. After laser operation, the trial side was given a soothing moisturizing repair cream, and the control side was given a placebo. By collecting the patient's facial pictures and objective skin data before and after the laser operation, 1 h, 1 d, 3 d, 7 d, 21 d, and combined with the researcher's semi-subjective evaluation and patient's subjective evaluation the wound skin reaction and wound healing were observed.Results:At 1, 3, 7, 21 days after laser operation, the skin water content of the test side was higher than that of the control side ( P<0.05), and the skin water loss was lower than the control side ( P<0.05); at 3, 7, 21 days, the skin pigment of the test side was lower than the control side ( P<0.05); at 3, 7 d, the test side skin erythema index was lower than the control side ( P<0.05); at 1, 3, 7 d, the test side wound skin erythema, edema, dryness and tightness, etc. were better than the control side ( P<0.05). The duration of pain, crusting time, scab removal time, and complete healing time of the wound on the test side were shorter than those on the control side ( P<0.05). The patient's satisfaction with the moisturization and comfort of the nursing products on the trial side was better than that on the control side ( P<0.05).

BACKGROUND: Regenerative medicine by using stem cells from dental pulp is promising for treating patients with critical limb ischemic (CLI). Here, we investigated the difference in the angiogenetic ability of stem cells from human exfoliated deciduous teeth (SHED) and human dental pulp stem cells (DPSC). METHODS: SHED and DPSC were harvested from dental pulp and analyzed in flow- cytometry for detecting the expression of surface markers. Levels of angiogenetic marker were examined by RT-PCR and Western-blot. Eighteen immunodeficient mice of critical limb ischemic model were divided into three groups: SHED, DPSC and saline, which was administered with SHED, DPSC or saline intramuscularly. Histological examination was performed to detect the regenerative results. RESULTS: A highly expression of CD146 was detected in SHED. Moreover, cells with negative expression of both CD146 and CD31 in SHED were more in comparison with those in DPSC. Expression of angiogenesis factors including CXCL12, CXCR4, Hif-1a, CD31, VEGF and bFGF were significant higher in SHED than DPSC by the RT-PCR and Western-Blot results. SHED induced more CD31 expression and less fibrous tissue formation in the critical limb ischemic model as compare with DPSC and saline. CONCLUSION Both SHED and DPSC possessed the ability of repairing CLI. With expressing more proangiogenesis factors, SHED may have the advantage of repairing CLI.
