Objective To investigate the usefulness of Utstein template to guide the assessment and study of cardiopulmonary resuscitation (CPR) in our medical practice because it has been popularized in many countries since 1991.Methods A prospective observational study using Utstein CPR registry form to evaluate the epidemiological features and outcomes of 511 patients resuscitated in the emergency department.Results Of 511 CPR patients registered,higher cardiac arrest rates were observed in the group of patients aged 40- 70 years. In 511 CPR patients registered,preexisting chronic diseases were common including cardiovascular diseases ( 190,37.2％ ) cerebrovascular diseases (48,9.4％ ) and respiratory diseases (39,7.6％ ).Of them,173 cardiac arrest patients (33.9％) had underlying cardiac causes,such as acute myocardial infarction (AMI) found in 109 (21.3％) patients,and ventricular fibrillation witnessed during first cardiac monitoring in eighty ( 15.7％ ) patients.The restoration of spontaneous circulation (ROSC) rate and survival rate at discharge of in - hospital cardiac arrest (IHCA) patients were 47.0％ and 13.5％respectively,but 16.7％ and 4.7％ respectively in the out - hospital cardiac arrest (OHCA) patients (P ＜0.01,both ). Conclusions This study indicated that the cardiovascular diseases, cerebrovascular diseases,and respiratory diseases were the most common preexisting chronic diseases found in cardiac arrest patients.Myocardial infarct,stroke and trauma were the most common precipitation causes of cardiac arrest in the recruited patients.The rates of ROSC and survival at discharge were significantly higher in statistics in patients with IHCA than those in ones with OHCA.

Objective To provide anatomical basis for preventing paresthesia that appear in the lateral thoracic wall ,the arm‐pit and the inside of the upper arm during axillary lymph node dissection for breast cancer .Methods The intercostobrachial nerve (ICBN) and its contiguous relationship were observed ,besides the origin ,ramus and branch were measured and recorded by anato‐mizing 30 adult embalmed cadavers (60 sides) .Results Three intercostals nerve (50 sides) and the ICBN (29 sides) were the mainly nerves in lateral thoracic wall ,the medical brachial cutaneous nerve(MBCN) was not observed .Three intercostals nerve , ICBN(42 sides)and MBCN(44 sides) were found in armpit ,but mainly was intercostobrachial nerve (42 sides) .ICBN and the MB‐CN equally distributed in the dorsal and medical of the upper arm ,but the three intercostals nerve was not observed .81 .7% (49 sides) of intercostal nerve and all of the brachial plexus presenced filament .They existenced blood vessel accompanied when the ICBN pierced the chest wall (63 .3% ,38 sides) .Conclusion Identify and intactly preserve the ICBN and relevant nerves and their filament during axillary lymph node dissection of the breast cancer may benefit to prevent paresthesia .

Objective To evaluate the adjuvant analgesia effect of the addition of dexamethasone to ropiva-caine in a transversus abdominis plane(TAP)block after inguinal herniorrhaphy. Methods 100 adult male pa-tients who underwent open tension-free inguinal herniorrhaphy from August 2015 to June 2017,randomized into two groups equally. TAP block with ropivacaine with additional dexamethasone was experiment group(group D) and with ropivacaine was control group(group C). Before the operation,all the patients were performed TAP block by the same group of surgeons. Celecoxib(200mg,Q12h,po)was prescribed to all patients in 48 hours after oper-ation. VAS and clinical symptoms were recorded. The sum and time of celecoxib consumption were also recorded af-ter 72 hours postoperatively. The surveys about the Carolinas comfort scale(CCS)of all the patients one week after operation were collected. Results The averaged pain score in 48 hours after operation has no statistical signifi-cance. The occurrence of postoperative nausea and vomiting of group D is lower than group C,neither of them were statistically significant. The averaged CCS of group D was lower than group C;the difference was significant. Con-clusions Compared to single usage of ropivacaine in the single-shot TAP as a preemptive analgesia method for in-guinal herniorrhaphy,adding dexamethasone to ropivacaine didn′t show significance in analgesic intensity after in-guinal herniorrhaphy,though the adjuvant usage of dexamethasone reduced the sum and duration of other analgesic medications and enhanced the comfort of the patients after mesh-used herniorrhaphy.

Objective To look into the effect of ubiquitin (Ub) in muscles of gastric cancer patients on their nutritional status and prognosis.Methods Abdominal rectus muscles of 102 patients with gastric cancer and 53 patients with benign abdominal diseases were studied.The expressions of Ub mRNA and protein were assessed through real time-PCR and Western blot.Results The relative expression of Ub mRNA in rectus abdominis muscles of gastric cancer patients (4.10± 1.04) was significantly upregulated compared with the control group (3.17±0.32) (t =7.386,P=0.000).The expression of Ub protein in rectus abdominis muscles of patients with gastric cancer was upregulated compared with the controls (0.151 ±0.058 vs.0.084±0.046,t =7.275,P =0.000).The high expression of Ub mRNA in rectus abdominis muscles of gastric cancer patients was significantly associated with decreases in weight,body mass index,prognostic nutritional index,serum albumin and hemoglobin (x2 =11.780,6.557,11.849,15.742,8.360;P=0.001,0.010,0.001,0.000,0.004).The high expression of Ub mRNA in rectus abdominis muscles of gastric cancer patients was not correlated with the patients'sex,age,tumor size or Borrmann type (x2 =0.038,1.978,0.486,1.483;P=0.774,0.160,0.486,0.223),but it was related to the pathologic type,lymph node metastasis and TNM staging of gastric carcinoma (x2 =11.260,9.362,20.517;P=0.004,0.002,0.000).The survival rate of gastric cancer patients with high expression of Ub mRNA was lower than those with low expression (x2 =5.775,P =0.016).Conclusions Ub mRNA and protein were upregulated in rectus abdominis muscles of gastric cancer patients.The high expression of Ub mRNA in these patients was related to their nutritional status and prognosis,which might play an important role in the development of cachexia.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
