ABSTRACT
Objective:To assess the efficacy of the newly constructed system for screening, managing and monitoring congenital heart disease (CHD) in neonates of Hainan Province, thus providing references for a further promotion.Methods:Clinical data of neonatal CHD in Hainan Province from January 1, 2019 to December 31, 2021 were retrospectively analyzed, including screening, diagnosis and treatment, prognosis and follow-up.Relying on Hainan Women and Children′s Medical Center as the leading unit, a neonatal CHD screening, diagnosis, treatment, and monitoring system was established.A dual-indicator method was adopted, that was, screening staffs in Hainan Province performed CHD screening in living neonates by cardiac auscultation and pulse oximetry (POX) within 6-72 h after birth.Echocardiographic examinations for the screened living neonates were performed in the 31 authorized diagnosis institutions.Evaluations, interventions and treatment of living neonates with CHD were performed in 6 authorized tertiary hospitals.Data of screening, diagnosis, evaluation and treatment were filled in, uploaded and managed online through the neonatal CHD screening information management system.The research team of our hospital was responsible for the data management and monitoring.Results:From January 1 st, 2019 to December 31 st, 2021, there were 329 387 living neonates in Hainan Province, and 321 447 (97.59%) were screened for CHD, and the annual screening rate increased year by year.The positive rate of CHD screening was 2.50%(8 032/321 447). The rate of cardiac ultrasound examination within 1 week of CHD positive screening was 94.66%(7 603/8 032). The referral rate of severe CHD was 100.00%(154/154). The overall prevalence of CHD in neonates of Hainan Province was 3.419‰ (1 099/321 447). Atrial septal defect was the most common CHD lesion, with a proportion of 38.40%(422/1 099). The sensitivity of cardiac auscultation, POX and their combination for CHD detection were 69.15%, 33.49% and 91.90%, respectively, and the specificity were 98.36%, 99.43% and 97.81%, respectively.At the initial screening, the ratio of dual-positive of cardiac auscultation and POX in neonates with severe CHD (serious and critical CHD) was significantly higher than that of a single positive indicator ( χ2=36.502, 46.214, respectively; all P<0.001). All neonates with CHD were evaluated.Fifteen neonates with severe CHD died.From 2019 to 2021, the standardized mortality rate of children aged 0-1 years with CHD in Hainan province was 4.67/100 000 (15/321 447). Conclusions:Dual-indicator screening for CHD (cardiac auscultation plus POX) is reliable, non-invasive, and simple, which is conducive to be clinically promoted.Introducing and promoting an appropriate technology for screening, diagnosis, and evaluation of neonatal CHD are extremely significant since they may have contributed to the timely diagnosis and treatment of CHD, especially severe CHD, thus lowering the mortality.
ABSTRACT
Objective:To investigate the key points of diagnosis and treatment of glycogen storage disease type Ⅱ(GSD Ⅱ).Methods:The clinical data of one child patient with GSD Ⅱ who received treatment in Hainan Children's Hospital on May 7, 2017 were retrospectively analyzed.Results:The child presented with atypical clinical manifestations, including pneumonia first, accompanied by muscle weakness and elevated muscle enzymes. Whole-genome sequencing showed that there were two heterozygous mutations in the acid alpha-glucosidase (GAA) gene, c.871C > T and c.1447G > A. The child was diagnosed with GSD Ⅱ.Conclusion:GSD Ⅱ has atypical clinical manifestations. It is easily misdiagnosed. Early whole-genome sequencing is helpful for the diagnosis of GSD Ⅱ.
ABSTRACT
OBJECTIVE:To investigate the clinical efficacy and safety of recombinant human epidermal growth factor(rhEGF) combined with lipoic acid in the treatment of diabetic foot. METHODS:A total of 68 patients with diabetic foot were randomly divid-ed into observation group and control group with 34 cases in each group. Both groups were given conventional therapy and Lipolic acid injection 0.6 ml added into Sodium chloride injection 250 ml. ivgtt(protecting form light),qd;observation group was additionally giv-en rhEGF for external use 1 ml and vaseline on the wounds,gauze dressing,qd. Treatment course of 2 groups lasted for 7 d. Clinical efficacy,ulcer area,the expression of Bcl-2 and Bax were compared between 2 groups as well as the occurrence of ADR. RESULTS:The total effective rate of observation group(94.1%)was significantly higher than that of control group(67.6%),with statistical sig-nificance (P0.05). After treatment,ulcer area decreased significantly, the level of Bcl-2 increased significantly in 2 groups,while the level of Bax decreased significantly;the improvement of observation group was more significant than that of control group,with statis-tical significance(P0.05). CONCLU-SIONS:rhEGF combined with lipoic acid is effective for diabetic foot with good safety.
ABSTRACT
Objective To investigate the protective effect and mechanism of recombinant hirudin on avulsed flap and to explore the application of recombinant hirudin in clinical treating avulsed flap.Methods 108 Sprague-Dawley rats were randomly divided into three groups:local injecting recombinant hirudin (group A),local injecting low molecular heparin (group B),and local injecting physiological saline (group C).The far ends were sutured after forming dorsal avulsed flap with local freeing.The levels of P-selectin and VEGF were detected,and the inflammatory cell aggregation and formation of microthrombus were observed in pathological section.On 14th postsurgery day the survival rate of flap was calculated.Results The content of P-selectin in group A was lower than that of groups B and C,with a statistical difference (P＜0.05).The content of VEFG in group A was higher than that of groups B and C,with a statistical difference (P＜0.05).On 14th postsurgery day,group A was higher than that in groups B (P＜0.05)and C (P＜0.01) in the survival rate of flap.Conclusions Locally injected recombinant hirudin can actively suppress the production of P-selectin,reduce accumulation of inflammatory cells,prevent information of microthrombus,improve ischemia and anoxia of avulsed flaps,decrease injuries of endotheliocyte,enhance the expression of VEGF,and stimulate hyperplasia of neogenesis capillaries that elevate survival rate of avulsed flaps.
ABSTRACT
ObjectiveTo explore the value of CT virtual endoscopy in the treatment strategies in low rectal cancer surgery.MethodsFifty- seven cases of rectal cancer in Jining First Hospital were collected,preoperative rectum CT virtual endoscopy,detailed records of patients with rectal invasion and the circumstances surrounding lymph nodes were investigated.Differences were compared in patients after routine pathological examination.And the distance of the tumor from the anal margin was compared with the preoperative rectum on rectal examination and rectal CT virtual endoscopy.ResultsPreoperative rectum CT virtual endoscopy had no significant difference in evaluation of metastases of the surrounding lymph nodes.Compared with postoperative pathological examination( x2 =2.5,P ＞ 0.05 ),while had significant difference in evaluation in perirectal infiltration( x2 =4.44,P ＜ 0.05 ).Rectal examination and rectum CT virtual endoscopy had no significant difference judgement of the tumor from the anal margin ( P ＞ 0.05 ).ConclusionsCT virtual endoscopy has a great significance in the preoperative evaluation of rectal cancer surgical treatment strategies,which should be further studied.
