Medical records are an important carrier of clinical medical information. With the technique of the CD mirror, medical records saved in CDs via scanning are stored in the server of the CD mirror, thus enabling realtime visit, retrieval, search, browse and transfer, improving the environment of medical record storage, and enhancing working efficiency and the utilization of the records. At the same time, relevant statistical surveys and analyses can be conducted with the software of medical record control, rendering information control scientific and standardized and finding an effective channel for the further exploration and utilization of the resources of medical information.

Clinical data of 129 young pafienm with lung cancer were analyzed retrospectively.Adenocarcinoma was the main pathologic type of lung cancer(n=62,48.1%),followed by undifferentiated small cell carcinoma(n=35,27.1%),squamous carcinoma(n=20,15.5%).Forty four cases were misdiagnosed at first consultation with a misdiagnosis rate of 34.1%.To avoid misdiagnosis seems to be the key issue for improvement of prognosis in young patients with lung cancer.

Objective To investigate the biological effects of low intensity of pulsed ultrasound (LIPUS) on human periosteal cells and marrow stromal cells in vitro. Methods LIPUS of 30 mW/cm2 was used to stimulate the cultured human periosteal cells and marrow stromal cells for 5 min, 10 and 20 min per day, respectively, followed by the examination of cell proliferation and differentiation potential. Results Thymidine incorporation and total protein assay indicated that LIPUS had no significant effect on DNA and protein synthesis of the periosteal and marrow stromal cells, suggesting that LIPUS did not promote proliferation of these cells. However, ALP activity and osteocalcin secretion of the human periosteal cells were dramatically increased. Conclusion The results suggested that low intensity pulsed ultrasound stimulated periosteal cell proliferation and differentiation toward osteogenic lineage, this might contribute to the curing effect of low intensity pulsed ultrasound for fracture.

Objective To investigate the clinical and imaging features in patients with vertebrobasilar dolichoectasia (VBD) through a comparative study in patients with ischemic stroke with or without VBD.Methods The patients with acute cerebral infarction were divided into either a VBD group or a non-VBD group according to magnetic resonance angiography.The VBD group was further divided into an anterior circulation infarction subgroup and a posterior circulation infarction subgroup.The cardiovascular risk factors,the diameter of basiar artery (BA),bifurcation height,and horizontal displacement were compared in all groups.Results A total of 269 patients with acute cerebral infarction were included,28 had VBD,accounting for 10.41％ of the patients with acute cerebral infarction during the same period.The proportion of male patients (78.6％ vs.66.8％ ;x2 =4.392,P =0.036),age (70.38 ± 10.58 years vs.62.86 ± 12.20 years; t =2.870,P =0.009),and the proportion of hypertension (89.3％ vs.47.7％ ; x2 =17.367,P =0.000) in the VBD group were significantly higher than those in the non-VBD group.The multivariate logistic regression analysis showed that the advanced age (odds ratio [OR] 1.248,95％ confidence interval [CI] 1.137-1.371; P=0.000),hyperglycemia (OR 1.599,95％ CI 1.181-2.164; P =0.002),hypertension (OR 1.251,95％ CI 1.020-1.534; P =0.032) and increased triglyceride level (OR 1.876,95％ CT 1.021-3.445; P =0.043) were the independent risk factors for VBD,while female gender (OR 0.133,95％ CI 0.024-0.735; P =0.021) was the independent protective factor for VBD.Of the 28 cerebral infarction patients with VBD,9 had anterior circulation infarction and 19 had posterior circulation infarction.There were significant differences in BA diameter ([5.40 ± 0.49] cm vs.[6.00 ± 0.77] cm; t =2.046,P =0.041),and the proportions of high score in bifurcation height (x2 =6.768,P =0.037) and horizontal displacement (x2 =5.241,P =0.042) between the 2 groups (all P ＜0.05).The multivafiate logistic regression analysis showed that the BA bifurcation height was an independent risk factor for posterior circulation infarction (OR 1.347,95％ CI 1.069-2.457; P =0.038) in patients with VBD.Conclusions VBD accounted for 10.41％ of the patients with acute cerebral infarction during the same period.Advanced age,hyperglycemia,hypertension and increased triglyceride level were the independent risk factors for VBD.Female gender was the independent protective factors for VBD,and the BA bifurcation height was an independent risk factor for VBD occurring posterior circulation infarction.

Objective To investigate the incidence and clinical characteristics and look for assay or examination indexes or indicators with higher sensitivity and specificity of heart damage induced by exhaustive exercise in order to establish its preliminary clinical classification and diagnostic criteria. Methods In a military region for training staff,the clinical data of 88 soldiers who were admitted to the departments of cardiology in 6 general or central hospitals because of exhaustive exercise from January 2000 to December 2010 were analyzed. The myocardial enzyme, electrocardiogram(ECG),echocardiography and other related examination indexes or indicators were observed,and the changes of symptoms,signs and other relevant assay and examination indexes before and after treatment were recorded. Results Exhaustive exercise could cause the symptoms such as chest tightness,palpitations,chest pain, dizziness,shortness of breath,fatigue,syncope and other symptoms,as well as cardiac auscultation abnormalities. After treatment, aspartate aminotransferase〔AST(U/L):20.34±6.33 vs. 35.43±25.25〕,α-hydroxybutyrate dehydrogenase〔α-HBDH(U/L):130.47±9.04 vs. 168.93±62.69〕,lactate dehydrogenase〔LDH(μmol?s-1?L-1):2.48±0.62 vs. 3.58±1.34〕,creatine kinase〔CK(U/L):125.58±67.56 vs. 556.42±381.89〕,creatine kinase isoenzyme〔CK-MB(U/L):11.20±4.08 vs. 23.09±15.61〕were significantly lower than those before treatment(P<0.05 or P<0.01);cardiac troponin T(cTnT)was detected in 5 patients,its level after treatment was significantly lower than that before treatment(μg/L:0.07±0.05 vs. 1.26±0.78,P<0.05). The ECG abnormalities included primarily sinus bradycardia (16 cases),sinus arrhythmia (13 cases) and premature ventricular contractions (11 cases). Echocardiographic abnormalities appeared in 18 cases,they were chiefly as follows:valvular regurgitation, cardiac dysfunction,cardiac enlargement,etc,among which the most common one was valvular regurgitation(all the refluxes were of small amount). Based on the above clinical manifestations and examination results,the exhaustive cardiac injuries were preliminarily divided into common type(20 cases),arrhythmia type(56 cases),heart failure type(2 cases)and sudden death(10 cases). Conclusions The clinical manifestations of exhaustive heart damage may appear in different types. Abnormal changes of myocardial enzymes,ECG and echocardiography are the strong evidences for the damage. Clinicians should pay attention to its prevention and treatment.

Objective To study the effect of morin on LPS induced acute lung injury mouse model and its mechanism .Meth‐ods Thirty male C57B/L mice were randomly divided into control group ,LPS group and LPS+ morin group ,with 10 in each group .5 mg/kg LPS was instilled into the lung from an trachea intubation in LPS group and LPS+morin group .Then the mice in LPS+morin group received an intraperitoneal injection of morin (40 mg/kg) every day for the next 3 d .Others received an equal a‐mount of saline .After 72 h ,the mice were sacrificed .The bronchoalveolar lavage fluid (BALF) was collected and centrifuged;the sediments were stained with Wright‐Giemsa for total cell and neutrophil count and the supernates were prepared for ELISA .The wet and dry weight of lung was weighed to calculate the wet/dry weight ratio .HE staining was performed to examine the pathologi‐cal change of lung .Western blot was used to determined the expression of TLR4 ,IKK and NF‐κB .Results Intratracheal instillation of LPS successfully established ALI model in mouse .LPS caused significant pathological changes including inflammatory cells infil‐tration ,alveolar septa thickness ,hemorrhage and edema .The wet/dry weight ratio ,the total cell count ,neutrophil count ,TNF and IL‐1βlevel in BALF ,and the expression of TLR4 ,NF‐κB ,and IKK were all increased significantly (P<0 .05) ,which were allevia‐ted by intraperitoneal injection of morin .Conclusion Morin can dampen the inflammatory response during LPS induced ALI in mouse ,which is potentially attributed to its inhibitory effect on the activation of NF‐κB .

Objective To investigate the effects of (?)doxazosin [(?)DOX] and its enantiomers on the myocardial morphology,cell cycle and cell apoptosis in rabbits fed with high fat diet. Methods Male New Zealand white rabbits were fed with high fat diet for 4 weeks. Forty such rabbits with hyperlipemia were then divided into atherogenic diet group (model),model + (-)doxazosin [(-)DOX] group,model + (+)doxazosin [(+)DOX] group and model + (?)DOX group (10 each). Another 10 rabbits were included as normal control group. In those drug-treated groups,1.0mg/kg of doxazosin or its enantiomers were intraperitoneally administered for 9 weeks; rabbits in normal control group and atherogenic diet group were given sterile distilled water. Percentages of myocardial cells in G0/G1 phase and in S phase,proliferation index (PI) and apoptotic rate of myocardial cells were compared among the groups,and the effects of doxazosin and its enantiomers were evaluated. Results Of the animals in atherogenic diet group,the proportion of myocardial cells in G0/G1 phase increased significantly (P0.05). No histomorphological alterations were observed in myocardial cells of the rabbits in normal control group. Pathological changes in myocardial cells were observed in the rabbits of atherogenic diet group,such as vacuolar degeneration,fatty degeneration,focal myocardial necrosis,myocardial fibrosis and focal lymphocyte infiltration. The pathological changes in myocardial cells were significantly ameliorated in the animals in (-)DOX and (?)DOX group,but aggravated in the rabbits of (+)DOX group. Conclusions A long term treatment with (-)DOX in the rabbits may improve the histopathological changes in myocardial cells caused by high fat diet. (-)DOX and (+)DOX may have a optical selective effect.

OBJECTIVE:To observe the clinical efficacy and ADR of ultrasound debridement combined with Huangma tinc-ture in the treatment of diabetic foot ulcer. METHODS:90 diabetic foot ulcer patients were randomly divided into combination treatment group(ultrasound debridement combined with Huangma tincture wet compress),Huangma tincture group(Huangma tinc-ture wet compress) and control group (vaseline) with 30 cases in each group. 3 months after treatment,Ulcer healing rate,cure time,effective time,recovery time,cure rate and ADR were observed in each group. RESULTS:The ulcer healing rate of combi-nation treatment group was significantly higher than that of Huangma tincture group and control group,with statistical significance (P<0.05);there was statistical significance between Huangma tincture group and control group(P<0.05). Mean cure time,effec-tive time and recovery time of combination treatment group were all significantly lower than Huangma tincture group and control group,with statistical significance(P<0.05);there was statistical significance between Huangma tincture group and control group (P<0.05). Cure rate of combination treatment group was higher than that of Huangma tincture group and control group,with statis-tical significance (P<0.05);there was statistical significance between Huangma tincture group and control group (P<0.05). No ADR was found in combination treatment group and Huangma tincture group. CONCLUSIONS:The ultrasound debridement com-bined with Huangma tincture in the treatment of diabetic foot ulcer improve healing rate and shorten healing time significantly with-out obvious ADR. It has good clinical efficacy.

Objective To investigate the effects of glucocorticoid on the changes of serum cortisol and 24-hour urinary cortisol in patients undergoing rheumatic valve replacement.Methods 86 patients undergoing rheumatic valve replacement were respectively given 1000 mg methylprednisolone during extracorporeal circulation and intravenously injected 10 mg dexamethasone on the first three days after operation.The enzyme-linked immunosorbent assay (ELISA) was taken to detect the serum cortisol concentration and 24-hour urinary cortisol on the day before operation,the 1st,3rd,5th,and 7th day after surgery.The postoperative complications such as the surgical incision and pulmonary infection were observed during the recovery days.Results Serum cortisol concentrations for patients with different preoperative cardiac function classifications had no significant difference at each observation point during the perioperative period (P＞0.05).Serum cortisol concentration showed a downward trend during the first 3 days after surgery.The serum cortisol level on the 3rd day after surgery was lower compared with that before surgery (P＜0.05),whereas 3 days later the serum cortisol concentration increased gradually and got back to the preoperative levels on the 5th day after surgery.The 24-hour urinary cortisol rose to the peak level on the 1st day after surgery,then decreased to the preoperative level on the 3rd day after surgery (P＞0.05).All the patients recovered.No one died or had complications such as pulmonary infection or incisions healing problems.Conclusions The effects of corticosteroids on perioperative serum cortisol levels in patients with rheumatic heart disease were not clearly correlated with preoperative cardiac function classification.Using glucocorticoid in the first three days after surgery reveals transient inhibitory effect on serum cortisol secreting,however,the cortisol level can quickly go back to the preoperative level after stopping giving glucocorticoid.
