Purpose　The aim is to investigate the hemostatic and protective effect of fibrin sealant(FS) on liver trauma in rats.Methods　On the surface of cracked wound(type Ⅰ) and resected wound(type Ⅱ)，spraying of FS or thrombin or direct suturation, was used receptively. Natural hemostasis was used as control.During postoperation the hemostatic time and the state of wound healing on 1st, 4th, 7th,14th, 50th day were observed.Results　Compared with the natural hemostasis,the hemostatical time of the FS group was shorter 86.0%(P＜0.01)in liver trauma type Ⅰ and 79.0%(P＜0.01)in liver trauma type Ⅱ.Compared with the thrombin group,the hemostatical time of the FS group was shorten 45.0%(P＜0.01)in liver trauma type Ⅰ and 84.0%(P＜0.05) in liver trauma type Ⅱ.The wound surface of FS group was healed faster than that of other groups.Conclusion　FS was an effective hemostatic and healing-promoter on liver trauma of rats.

Objective To investigate the relationship and mechanism between the serum level of high mobility group box protein-1(HMGB1)and the mortality rate in patients with sepsis.Methods The serum levels of HMGB1,superoxide dismutase(SOD)and malondialdehyde(MDA)in 48 patients with sepsis were determined.The clinical outcomes in those patients were recorded and anlyzed.Results After the onset of sepsis,the serum HMGB1 levels of both death group and survival group were increased gradually and peaked at 72h after the onset of the disease.The semm HMGB1 levels of death group were much higher than those of survival group except at 24h(t=6.07,6.20,24.43,all P＜0.05).The activity of serum SOD of death group was markedly lower than that of survival group at 12h,24h,48h and 72h(t=10.24,20.61,11.67,33.33,all P＜0.05),and the level of serum MDA of death group was significantly higher than those of survival group at all time points(t=26.06,22.17,23.86,9.49,5.95,all P＜0.05).There was a significantly positive correlation between the serum HMGB1 and MDA level.Conlusioa The increase in serum HMGB1 level may be the important reasoll for the increased mortality rate in patients with sepsis;Oxidant/antioxidant imbalance may be olle reason for the increase in serum HMGB1 level.

Objective To investigate the clinical features of acute traumatic subdural hematomas (SDH) in infants and discuss the treatment methods. Methods The clinical features of 48 infants under three years old with acute traumatic SDH admitted from 2002 to 2008 were retrospectively analyzed.Results There were 31 infants under one year old (65%). The most popular injury cause was accidental fall in 37 patients (77%). Of all patients, 12 patients (25%) had disturbance of consciousness,eight ( 17% ) had convulsion and eight ( 17% ) were combined with skull fractures. The treatment methods included craniotomy and evacuation of the blood clot in 18 patients ( including 13 patients underwent instant operation after admission ), burr hole craniotomy and external drainage of the chronic subdural hematoma in seven and conservative management in 23 with small subdural hematomas. All patients obtained good outcome except that two patients had motor dysfunction and one death. Conclusions The incidence of acute traumatic SDH in infants is high, especially in infants under one year old. It is easy to be disregarded at early stage and may deteriorate to chronic subdural hematoma or hydropsy. Early diagnosis and active surgical treatment may attain sound prognosis.

Objective To investigate the effects of the point-injection combined with neuromuscular facilitation rehabilitation techniques on post-stroke shoulder-hand syndrome. Methods A treatment group, 36 cases, was treated with the point-injection combined with neural facilitation of rehabilitation techniques. And a control group, 30 cases, was treated with massage therapy. Observed the clinical manifestations and used Fugl-Meyer to assess the joint activities, pain degree and motion function of upper limbs before and after therapy. Results Compared with the control group, the treatment group showed better improvement of joint activity scope and degree, and alleviation of pain (P<0.05). Conclusion Point injection and neuromuscular rehabilitation treatment has a better effect ain treating sequelare of brain stroke and it is worth applying.

Objective To explore the clinical characteristics of posttraumatic cerebral massive infarction in children. Methods 68 cases were reviewed. Results There were 43 cases complicated with subarachnoid hemorrhage, 37 with brain contusion, 48 with fracture of skull,and the hematoma was subdural in 29 cases, epidural in 16 cases, and intracerebral in 14 cases. Other complications included fracture of limbs (24/68), thoracic or abdominal injury (15/68), and hemorrhagic shock (30/68). The infarction were found mostly in the first 7 d (range 2 h~13 d), and 32 cases within 4~7 d after the trauma. The outcome when discharged (according to the Glasgow outcome scale) was good recovery in 32 cases, moderate disability in 15 cases, severe disability in 9 cases, vegetative state in 4 cases, and 8 cases died. Conclusion The feature of the posttraumatic cerebral massive infarction in children is usually concealed by primary injury. CT and MRI are the bases for diagnosis.The outcome may be better than in the adults when early diagnosis and intervention has been produced.

Objective To retrospectively analyze echocardiography findings and left hearst function in patients with patent ductus arteriosus (PDA) after transcatheter closure. Methods 28 patients admitted between January 2012 and December 2012 in our hospital for PDA transcatheter closure were included. Assessment of cardiac structure, hemodynamics and cardiac function parameters during preoperation and in postoperation 3 days, 1 month and 6 months were studied. Results Statistical significant difference was found at 3 days, 1 month and 6 months postoperation when compared with pre-operation in terms of left atrial diameter, left ventricular end-diastolic diameter, left ventricular end systolic diameter and other doppler measurements ( all P < 0. 05 ) . Six-minute walk test ( 6MWT) tolerance improved when compared to preoperation level (P < 0. 05). Better improvement in LVEF and LVES was observed in patients age ≤14 years old when compared to patients > 14 years old after operation ( P < 0. 05 ) . Conclusions Transcatheter closure of PDA can improve cardiac function and correct early hemodynamic abnormalities patients in younger age group show more benefit from the procedure.

OBJECTIVETo explore the management of obstructive hydrocephalus caused by posterior fossa tumors before tumor resection in children.

METHODSThe clinical data were reviewed of 162 pediatric patients of posterior fossa tumors with obstructive hydrocephalus undergoing surgical tumor removal between January 2008 and June 2012. Ninety children received preoperative Ommaya external drainage (group A) and 72 underwent preoperative ventriculo-peritoneal shunting (V-Ps) (group B). The therapeutic effects were evaluated and compared between the two groups.

RESULTSPostoperative complications found in a total of 67 cases including infection (27), shunt blockage (19), subdural hematoma or effusion (16), ventricle fissure syndrome (5), and tumor hernia (4). Significant differences were found in the incidences of shunt blockage (P=0.047) and subdural hematoma or effusion (P=0.039) but not in the incidences of intracranial infection (P=0.478) or tumor hernia (P=0.462) between the two groups.

CONCLUSIONOmmaya reservoir can produce good results through simple surgical procedures for treatment of acute hydrocephalus in children with posterior fossa tumors and is associated less trauma and complications.

Objective: To learn the human resource development of provincial,municipal and county-level centers for disease control and prevention（CDCs）in Zhejiang Province from 2010 to 2017,and to provide evidence for optimizing human resource allocation . Methods: We obtained the human resource data of CDCs in Zhejiang Province from national information system for disease control and prevention,and analyzed the changes in the number of permanent staffs,the number of permanent staffs per ten thousand permanent residents as well as the composition of the age,education level,professional background and title in provincial,municipal and county-level CDCs from 2010 to 2017 . Results: The number of the permanent staffs of CDCs in Zhejiang Province increased from 4 592 to 4 835 from 2010 to 2017. In 2017,the number of permanent staffs in overall,provincial,municipal and county-level CDCs per ten thousand permanent residents were 0.855,0.068,0.186 and 0.600,respectively,all of which did not meet the standard. The main age group of CDC staffs changed from 25-34 years old in 2010 to 35-44 years old in 2017. The staffs of overall,provincial,municipal and county-level CDCs mainly had Bachelor's degrees in 2010,while the staffs of provincial CDCs mainly had Master's degrees and above in 2017. The percentages of staffs who had Bachelor's degrees and above in overall,provincial,municipal and county-level CDCs in 2017 increased to 75.12%,90.36%,80.76% and 71.65%,respectively. The CDC staffs were mainly public health professionals,and the percentage increased from 2010 to 2017. The percentages of public health and laboratory medicine professionals in overall,provincial,municipal and county-level CDCs in 2017 increased to 71.56%,79.17%,70.14% and 71.15%,respectively. The CDC staffs mainly had intermediate title,and the percentage of senior title in overall,provincial,municipal and county-level CDCs in 2017 increased to 25.58%,38.80%,32.99% and 21.79%,respectively . Conclusion From 2010 to 2017,the structure of education level,professional background and title of CDC staffs in Zhejiang Province were further optimized,but there was a lack of permanent staffs and a decrease in the staffs under 35 years old.

Objective:To evaluate the clinical performance of anti-peptidylarginine deiminase 2 (PAD2) and anti-PAD4 antibodies combined testing in a Chinese rheumatoid arthritis (RA) cohort.Methods:A total of 148 RA inpatients and 35 patients with non-RA arthritis as controls (DC) were recruited from November, 2018 to November, 2019 in Peking University People′s Hospital. In addition, a total of 44 healthy controls (HC) who went to Peking University People′s Hospital for annual physical examination were collected from June 2019 to July 2019. The α-PAD2 and α-PAD4 level in clinical specimens were determined by ELISA. Statistical analysis was performed by the Mann-Whitney U test, the Kruskal-Wallis (KW) test, the χ 2 test or the Fisher′s Exact Test, as necessary. Correlation analysis were performed by logistic regression. Results:α-PAD2 and α-PAD4 were present in 26.4% (39/148) and 20.9% (31/148) patients with RA, 5.7% (2/35) and 5.7% DC (2/35) and 4.5% (2/44) and 2.3% HC (2/44), respectively. α-PAD4-positive RA patients displayed significantly longer disease duration compared to α-PAD4-negative RA patients (17.3±13.2 years vs 8.6±10.2 years, P<0.001). α-PAD4-positive RA patients showed a significantly higher incidence of interstitial lung disease (ILD) compared to those without α-PAD4 (54.8% vs 25.6%, P=0.002). No associations between α-PAD2 and ILD were found ( OR: 0.797, P=0.579). In contrast, significant associations between α-PAD4 and ILD were found ( OR: 3.521, P=0.002). In seropositive RA, α-PAD4 displayed a weak correlation with ILD ( OR: 2.324, P=0.046), but this association was greatly enhanced when combined with α-PAD2 [anti-PAD2 (-)] ( OR: 4.059, P=0.007). Conclusions:The findings delineate the clinical relevance of α-PAD2 and α-PAD4 in RA and suggest that the combined testing for α-PAD2 and α-PAD4 may provide additional diagnostic value to the current clinically available assays in RA, in particular in identifying patients at risk of RA-ILD.

Objective:To investigate whether intestinal rehabilitation therapy (IRT)could optimize the effectiveness of IRT in patients with short bowel syndrome (SBS) caused by acute mesenteric ischemia (AMI) with chronic multivessel lesions.Methods:Clinical data of 18 hospitalized patients diagnosed with AMI leading to SBS and undergoing IRT at the Eastern Theater General Hospital of the People's Liberation Army from Jan 2012 to Oct 2023 was retrospectively analyzed.Result:Following IRT, the revascularization group showed significantly greater increases in ASMI and grip strength compared to the control group [(0.28±0.26) kg/m 2vs. (0.02±0.21) kg/m 2, P=0.033, and (0.97±0.33) kg vs. (0.48±0.34) kg, P=0.007, respectively]. Similarly, the increase in EN intake was significantly higher in the revascularization group compared to the control group [(572.5±93.6) ml/d vs. (375.2±176.3) ml/d, P=0.012], accompanied by a greater improvement in intestinal nitrogen absorption rate [(25.06±14.06)% vs. (13.84±4.62)%, P=0.034] and a more substantial decrease in GSRS scores [(-15.88±3.94) vs. (-6.33±5.13), P=0.030]. Moreover, there were significant differences in the composition of EN formulations between the two groups after IRT ( P=0.046). Additionally, SF-36 scores at discharge were significantly higher in the revascularization group than that in the control group for five indicators including BP, GH, VT, SF, and MH ( P<0.05). Conclusions:For patients with SBS resulting from AMI by chronic multivessel lesions, revascularization therapy may not leading to higher growth in weight and hematological nutritional indicators during IRT, but it is beneficial for improving muscle function, improving EN absorption, increasing the likelihood of PN independence, relieving gastrointestinal symptoms, and enhancing overall quality of life.
