[Clinical observation of acupoint application of Chinese herbal medicine in preventing postoperative nausea and vomiting after orthopaedic surgery under general anesthesia].

OBJECTIVE: To explore clinical effect of acupoint application of Chinese herbal medicine in preventing postoperative nausea and vomiting after orthopaedic surgery under general anesthesia. METHODS: From January 2018 to December 2019, 168 patients who met inclusion criteria and were underwent selective spine surgery, were double-blind divided into two groups according to central random system, 84 patients in each group. In control group, there were 39 males and 45 females aged from 30 to 65 years old with an average of (53.83±9.17) years old, 37 patients were classified to typeⅠand 47 patients were typeⅡ according to American Society of Anesthesiologists (ASA) grading. In experiment group, there were 39 males and 45 females aged from 30 to 65 years old with an average of (54.08±9.00) years old; 32 patients were classified to typeⅠand 52 patients were typeⅡ according to ASA grading. Both of two groups were obtained acupoint application before anesthesia induction, and acupoint application were put on Zhongwan (CV 12) and bilateral Neiguan (PC 6) for 6 h, changed after 24 h, last for 2 d. The drug prescription of plasters in experimental group was consist of Rhizome Pinelliae Preparata, Ginger and Clove. The plasters in control group was consistent with drug plasters in experimental group in appearance and smell to the greatest extent. The ingredients were flour and excipients with 10% of experimental drug concentration. Incidence of nausea vomiting, visual analogue scale (VAS) of narusea degree at 24 h and 24 to 48 h after operation between two groups were compared, SF- 12 simple quality of life score before operation, 24 and 48 h after operation were also compared by using R3.6.1 Rstudio software by the third-party. RESULTS: There were no statistical differences in incidence of nausea vomiting, VAS of narusea degree at 24 h after operation (P>0.05), while there were no differences in incidence of nausea vomiting, VAS of narusea degree at 24 to 48 h after operation (P>0.05) . There were no statistical differences in SF-12 before operation, 24 and 48 h after opertaion (P>0.05). CONCLUSION: The curative effect of acupoint application of traditional Chinese medicine on the prevention and treatment of postoperative nausea and vomiting is not obvious.

Effect of acupuncture method of removing-stasisand resuscitating on the consciousness of patients with severe traumatic brain injury: A randomized clinical trial.

INTRODUCTION: With the development of social economy, transportation and various infrastructures have also developed, but it has objectively increased the number of patients with head injury. Although the current craniocerebral medicine technology continues to advance, long-term bed rest and other complications have led to an insignificant decrease in the mortality rate of coma patients. It is not uncommon for patients with disturbance of consciousness caused by head injury in major hospitals. METHODS/DESIGN: This will be a retrospective, single-blind clinical observational study. We will select 50 cases that meet the subject's selection criteria. According to whether they received acupuncture treatment or not, they will be randomly divided into 2 groups, namely treatment group and control group. The control group will be given conventional Western medicine treatment, and the treatment group will be given acupuncture method of removing-stasis and resuscitating treatment on the basis of the control group. DISCUSSION: Our purpose is to observe the role of acupuncture method of removing-stasis and resuscitating in promoting the recovery of patients with severe head injury. We aim to provide more evidence-based medical evidence for acupuncture treatment of this disease. TRIAL REGISTRATION: ClinicalTrials.gov, ChiCTR2000034732, Registered on 19 July 2020.

Molecular and Hematological Characterization of a Novel Translation Initiation Codon Mutation of the α2-Globin Gene (ATG>ATC or HBA2: c.3G>C).

Although mutations causing α-thalassemia (α-thal) are mainly larger deletions involving one or both of the duplicated α-globin genes, point mutations are not rare. We have identified a novel mutation of the translation initiation codon of the α2-globin gene with DNA sequencing and allele-specific multiplex ligation-dependent probe amplification (MLPA) in a Chinese family. RNA analysis was performed with reverse transcription-MLPA (RT-MLPA). A novel mutation at the translation initiation codon of the α2-globin gene (HBA2: c.3G>C) was identified. The proband and his father, who were both carriers of this mutation, had a hematological phenotype of mild α+-thalassemia (α+-thal) trait with low-normal limit of mean corpuscular volume (MCV) and normal Hb A2. RNA analysis showed markedly decreased levels of α-globin mRNA and the presence of a small amount of mutant mRNA. The HBA2: c.3G>C mutation most likely caused α-thal by lowering levels of wild α-globin chain. Our study increases the mutation spectrum of α-thal.
