OBJECTIVETo evaluate the clinical outcomes of patients with acute myocardial infarction (AMI) complicating cardiogenic shock underwent various treatments.

METHODSFrom January, 2002 to May, 2007, 47 AMI patients with cardiogenic shock were treated in our department by optimal medication (dopamine, epinephrine, norepinephrine, etc.), intra-aortic balloon pump (IABP), mechanical ventilation when indicated, percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). Outcome and factors related to mortality for these patients were analyzed in this retrospective study.

RESULTSBesides optimal medication and IABP in all patients, 31 patients underwent PCI (66.0%), 6 patients received emergency CABG (12.8%). The overall in-hospital mortality rate was 36.2% (17/47), 6 patients (14.9%) died before coronary revascularization and 11 patients (21.3%) died after revascularization. Nine patients died of pump failure and 8 patients died of renal and (or) respiratory failure. Regression analysis showed that acute renal failure (r = 0.734, P = 0.000), acute respiratory failure (r = 0.606, P = 0.000) and diabetes (r = 0.372, P = 0.012) were positively related to in-hospital mortality.

CONCLUSIONDespite improvements in treatment options for AMI patients complicating cardiogenic shock, in-hospital mortality remained high, especially for patients complicating further with acute renal failure and acute respiratory failure.

OBJECTIVETo delineate the clinical features and potential mutation of the ATP7A gene in a family affected with Menkes disease.

METHODSClinical data of a patient and his family members were analyzed. Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA) assays were performed to detect the mutation of the ATP7A gene.

RESULTSThe patient was admitted at the age of 5 months due to severe epilepsy and marked delayed psychomotor development. Significantly light complexion, pudgy cheeks and sparse fuzzy wooly hair were noted. Cranial magnetic resonance imaging and angiography revealed cortical atrophy, leukoencephalopathy and circuitous of intracranial vessels. The plasma ceruloplasmin was decreased. MLPA has identified a deletion spanning exons 8 to 12 of the ATP7A gene. His mother was found to be a heterozygous carrier of the same mutation.

CONCLUSIONThe clinical features and a novel mutation of the ATP7A gene of the family have been delineated.

【Objective】 To explore the effects of massive intraoperative RBC transfusion on multiple clinical test indicators and prognosis of patients, underwent tumor surgery in order to provide evidence for rational blood transfusion and effective intervention of complications caused by massive blood transfusion in tumor patients. 【Methods】 A total of 208 patients who underwent tumor resection in our hospital from January 2019 to December 2020 and received intraoperative RBC transfusion(>10 U) were selected as the study subjects. According to the amount of blood transfusion, they were divided into group A: 10~15 U, 144 patients; Group B: >15~25 U, 48 people; Group C: >25 U, 16 people. Data of liver function, coagulation, electrolyte, platelet count and short-term prognosis were collected and compared among 3 groups before and after surgery. 【Results】 No significant difference was noticed in patient pre-operation variables including ALT (U/L), AST (U/L) and TBIL (μmol/L) among three groups recieved massive blood transfusion (P>0.05), while AST was significantly lower than that after operation (P<0.05) : 105.33±238.18 vs 113.50±185.04 vs 291.25±457.33 (P<0.05). After operation, PT (s) (14.12±2.10, 14.79±2.67 and 16.10±4.06), INR(1.25±0.20, 1.31±0.26 and 1.44±0.38) and APTT (s) (30.52±5.63, 34.57±12.80 and 34.80±10.49) extended significantly than those before operation (P<0.05), while Plt (×10⁹/L) decreased significantly (142.32±70.07, 100.04±57.50 and 85.40±41.10)(P<0.05). After operation, serum K⁺ and Ca²⁺ decreased significantly, Na⁺ and Cl^- increased significantly, and pH value decreased (P < 0.05). Hospital stay of group C (d) was 33.73±34.62 vs 17.74±14.83 vs 20.92±17.69 (P<0.05). The mortality rate was 2.8%(4/44) vs 6.3%(3/48) vs 18.8%(3/16)(P<0.05), and mortality rate of group C was higher than the other two groups. 【Conclusion】 Postoperative dysfunction of liver and coagulation in tumor patients may be related to intraoperative RBC transfusions and consequent acid-base imbalance and electrolyte disturbance. The more the units of RBC transfused, the more abnormal the patients' clinical indicators, also the longer the hospital stay and the worse the short-term prognosis.

OBJECTIVETo analyze the epidemiological and etiological characteristics of diarrheal disease among children under 5 years of age in Guangdong province, in 2012.

METHODS64 hospitals in 21 cities were chosen as the diarrheal syndromic surveillance sites, of which 14 hospitals were selected to carry out etiological surveillance among children under 5 years of age, including isolation and culture of both Vibrio cholera and Shigella as well as nucleic acid detection of rotavirus and norovirus by PCR. Descriptive method was used to analyze data from syndromic and etiological surveillance programs on diarrheal, from 1932 parents of the children.

RESULTSIn 2012, the outpatient attendance rate on diarrheal among children under 5 years was 0.8%. The proportion of diarrheal in children under 5-year-olds was 63.5%, among the total number of diarrheal outpatients at the outpatient clinics under surveillance program. The morbidity of infectious diarrhea was 1454.5/10 million in children under 5 years of age. A total number of 1932 specimens were collected from children under 5 years of age, in the outpatient department. Among these specimens,Vibrio cholera appeared all negative but one was Shigella positive and proved to be Sh. sonnei. The positive rates of rotavirus and norovirus were 14.1% (273/1932)and 16.9% (326/1932). Both rotavirus and norovirus were found in 24 specimens, with a positive rate as 1.2% . 112 specimens were successfully gene sequenced for rotavirus, of which 33.9% as G1[P8] genotype, 25.9% as G9[P8], 12.5% as G2[P4] and 9.8% as G3[P8] respectively. 90 specimens were successfully gene-sequenced for norovirus, of which 76.7% as G II.4 genotype. Genetic subtypes of G II. 4/2006b, accounted for 50.0% and could be detected around the year except for June and December. New G II. 4/Sydney Strain_2012 was first detected in August and became the predominant in December. In addition, 5 specimens belonged to G I genotype with other 16 subtypes of G II.

CONCLUSIONResults from our study proved that children under 5 years of age belonged to high-risk group for diarrheal disease in Guangdong province. Rotavirus and norovirus were both diverse in terms of genome.

China Association of Chinese Medicine organized specialists in andrology of Chinese and western medicine to explore the population and treatment stage of benign prostatic hyperplasia （BPH） with Chinese medicine as the leading therapy. Chinese medicine has great advantages in the treatment of benign prostatic hyperplasia. However， it is necessary to make clear the stage when Chinese medicine or modern medical treatment can be used as the leading therapy， and the conditions under which Chinese and western medicine can be combined to achieve the best treatment efficacy. The specialists agreed Chinese medicine as the leading therapy for the treatment of BPH in the following populations or conditions： the elderly and weak patients with basic diseases， BPH symptoms， and cannot tolerate anesthesia and surgery， the patients with BPH symptoms and cannot tolerate the adverse reactions or the possible adverse reactions of western medicine； the patients with mild ［international prostatic symptom score （IPSS） ≤ 7］ or moderate lower urinary tract symptoms （IPSS ≥ 8） and the quality of life not significantly affected， the patients with bladder detrusor hypofunction， bladder dysfunction and cannot be treated surgically， or with incomplete bladder emptying after surgical treatment； the BPH patients with prostatitis as the main clinical manifestation， the patients with non-acute complications after operation. BPH is one of the dominant diseases in urology and andrology of Chinese medicine， and the symptoms， complications， and prognosis of BPH patients need to be fully considered during the clinical treatment. When Chinese medicine is taken as the leading therapy， it is essential to regularly review the serum level of prostate-specific antigen to exclude the possibility of prostate cancer， and apply Chinese medicine for full treatment course and cycle. At the same time， Chinese and western medicine can be combined to achieve the most effective， convenient， economical， and satisfactory treatment， which can carry forward the advantages of Chinese medicine in treating this disease.
