OBJECTIVE:To investigate the composition and medication regularities of prescriptions for Treatise on Febrile Dis-eases. METHODS:The prescriptions included in Treatise on Febrile Diseases were collected and inputted into TCM inheritance platform system(V2.5)software,and prescription database was established. The medication and the compatibility regularity of pre-scriptions were excavated using the function of software integration. RESULTS & CONCLUSIONS:83 kinds of TCM involved in 112 prescriptions ranked by frequency,among which 24 ingredients were used more than 4 times. Commonly used TCM groups were summarized to evolve 16 key groups and 8 new prescriptions. Four properties of TCM are mainly the property of“Wen and Han”,and five tastes mostly are“Sweet,Bitter,Spicy”. TCM with the property of“Wen and Sweet”taste are more than those with the property of“Wen and Spicy”,and TCM acting on spleen are more than those acting on lung.

Objective:To study the function of transcription factor 4 (TCF4) and to prepare TCF4 polyclonal antibody.Methods:pET-41/TCF4 was transformed into E.coli BL21(DE3) and induced by IPTG.The purified GST-TCF4 fusion protein was applied to immunize rabbit to produce antiserum. The specificity of the affinity of purified anti-TCF4 antibody was examined by Western blotting analysis of the eukaryotic expressed products of TCF4. Dig-labeled probe and antibody against TCF4 were used to examine the expression of TCF4 in Saos-2 cells under mechanical stretch. Results:Western blotting showed that the antibody could bind to TCF4 specifically. The expression of TCF4 mRNA and protein were significantly increased in Saos-2 cells under mechanical stretch. Conclusion: TCF4 antibody has been prepared successfully.

Time to positivity(TTP) is a new parameter in blood culture field.The article shows us the concepts of TTP,differential time to positivity (DTTP),and introduces their relation with bloodstream infection (BSI),catheter-related bloodstream infection (CRBSI).Besides,it stresses TTP' s clinical application,including determining the severity of disease;identifying the isolates whether pollution or not; identification of isolate strains ; detection of the drug resistance of isolates ; evaluating the effect of antibiotic ; helping to adjust the therapeutic drug; diagnosing or excluding CRBSI by means of DTTP;deciding whether the catheter is the source of infection in patients with candidemia; understanding the epidemiological distribution of strain.At the same time,the article also describes the shortcomings and domestic current status.

Objective To study the expressions of EGFR and VEGF in endometrium after danazol pretreatment and the pathological changes of endometrium. Methods A total of 60 patients with anovulartory functional bleeding were randomly divided into two groups: Danazol group and control group with 30 cases in each group. Danazol group were given transcervical resection of endometrium with danazol pretreatment, and control group without any pretreatment. The endometrium resected from uterus was sent for histological assessment, observation of the grandular quantity and stromal loose degree, and of the expressions of EGFR and VEGF in endometrium. Results The endometrium of patients who took Danazol were almost in proliferative phase(similar to early proliferative phase).The numbers of endometrial glands near the basal layer with Danazol pretreatment were lower than that in the control group; the stromal components (+～) were more compact than the contral group (～). The expression intensity and rates of EGFR and VEGF in glands were higher than those of stromal components. Danazol decreased the expression of EGFR and VEGF in endometrium compared to the control group. Conclusion Pretreatment with Danazol can suppress the prolifieration of endometrial cells, thin the endometrium,and disperse the glands, compact the stromal components, and it can also reduce the expressions of EGFR and VEGF in endometrial glands and stromal components compared with the control group.

Objective To investigate the clinical and endoscopical features of patients suffered from Henoch-Schonlein purpura (HSP). Methods Retrospective analysis of the clinical manifestation in 197 purpura patients, of which 81 cases were HSP, and described the endoscopic features of 19 cases who underwent gastroscopy and/or colonoscopy. The specimens from 15 cases were evaluated histopathologically. Results Eighty-one patients were diagnosed as HSP, 51 (63. 0% ) of them had a history of upper respiratory tract infection 1 -3 weeks before, taking antibiotics or animal protein prior to the onset of the illness. In 21 patients, abdominal symptoms presented firstly, which occurred 1 -40 days prior to the appearance of skin rashes. Seventy- four (91. 4% ) patients experienced abdominal pain, 37(45. 7% ) patients had digestive tract bleeding. Endoscopic features included diffused congestive edema of gastrointestinal mucosa, widespread hemorrhagic spots, erythema, erosion and ulceration. Lesions were relatively severer in small intestine than those in large intestine. Histological manifestations showed massive neutrophilic infiltration in mucosa and submucosa, fibrotic necrosis of small vessels, focal bleeding, erosion and ulceration. There was prominent accordance in the extents of endoscopic and pathologic manifestation with the severity of gastrointestinal symptoms. Conclusions Forty one percent of purpura patients presented as HSP, of them 26% had the abdominal symptoms firstly. Small bowel lesions were severer than those of stomach or colon. The typical features of the illness and endoscopic findings are very helpful to the early diagnosis of HSP.

Objective To investigate the significance of neutrophil gelatinase associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) in the patients of primary nephmpathy syndrome (PNS) complicated with acute kidney injury (AKI) by detecting urinary level of NGAL and KIM-1.Methods Senventy-two patients of PNS were selected as our subjects including 34 case with minimal change disease (MCD),23 cases with membranous nephropathy(MN),15 cases with mesangial proliferative glomerulonephritis (MsPGN).Fifteen cases of healthy physical examination were selected as control group.Meanwhile subjects were also divided into PNS with ATN group (15 cases) and PNS without ATN group (57 cases) according to their pathology check.ELISA was applied to detect the urinary level of NGAL and KIM-1,whose correlation with pathological type and clinical index were analyzed.Results The urinary level of NGAL and KIM-1 in patients with PNS were (42.37 ± 28.24) μg/L,(2.76 ± 1.11) μg/L respectively,higher than that of control group (P ＜0.01).The urinary level of NGAL in the MCD group,MN group,MsPGN group were higher than that of control group (46.81 ± 15.75) μg/L,(22.09 ± 7.69) μg/L,(15.31 ± 3.74) μg/L,(8.03 ± 0.35) μg/L respectively,P ＜ 0.05).The urinary level of NGAL in MCD group was significantly highest than that in the other groups (P ＜ 0.05).The urinary level of KIM-1 in the MCD group,MN group,MsPGN group were higher than that of control group(2.41 ±0.58) μg/L,(2.54 ±0.67) μg/L,(2.87 ±0.50) μg/L,(0.73 ±0.35) μg/L respectively,P ＜0.05).But there was no significant difference among MCD,MN,MsPGN groups(P ＞ 0.05).The urinary level of NGAL and KIM-1 in patients PNS were (42.37 ± 28.34) μg/L and (2.76 ± 1.11) μg/L,significantly higher than that of control group (t =4.668,12.665,P ＜ 0.05).The urinary level of NGAL and KIM-1 in patients PNS with ATN were significantly higher than patient without ATN (NGAL:(74.98 ±9.52) μg/L vs.(31.31 ±2.34) μg/L;KIM-1:(3.60 ±0.92) μg/L vs.(2.54 ±0.81) μg/L,P ＜0.05).The correlation analysis showed that the urinary level of NGAL and KIM-1 was positively correlated with serum β2-MG,serum creatinine,serum blood urea nitrogen and 24-hour urine protein.(r =0.432,0.299,0.234,0.254,0.434,0.650,0.276,0.301 respectively,P ＜ 0.05).Conclusion The urinary level of NGAL and KIM-1 could be considered as the early,non-invasive biologic factors to reflect in patients of PNS with ATN.

Objective To observe the blood flow changes of left ventricular cavity and quantify the energy loss (EL) and circulation of left ventricular during systole and diastole in patients with dilated cardiomyopathy(DCM) via vector flow mapping(VFM).Methods Thirty-six healthy volunteers and 32DCM patients were enrolled.According to the severity of mitral regurgitation(MR),DCM patients were divided into two groups.The quantitative parameters,including average energy loss(EL-base,EL mid,EL-apex) and circulation (vortex quantity,vortex area,circulation) were measured in the different periods of VFM imaging mode in apical four-chamber view,apical three-chamber view and apical two-chamber view respectively.The difference of parameters was evaluated between different groups during the different periods.The early transmitral valve blood flow velocity E,the late transmitral valve blood flow velocity A,the ratio of early transmitral valve blood flow velocity to the early diastolic mitral valve velocity E/e,the ratio of early transmitral valve blood flow velocity to the late transmitral valve blood flow velocity E/A and Tei index were derived via dual-Doppler imaging technology.Meanwhile,the correlation between VFM parameters with E,A,E/A,E/e or Tei index was also analyzed.Results ①The level of EL were decreased significantly among EL-mid and EL-apex during early diastole,EL-mid during mid-systole,EL-mid and EL-apex during late-systole (P ＜0.05),when compared with the control group.The vortex quantity,vortex area and circulation during early diastole and the vortex area and circulation during atrial contraction period were significantly different between two groups (all P ＜ 0.05).As for mid-diastole,only vortex area showed significant difference (P ＜0).01).(②) When compared with different grades of MR in DCM patients,the level of all segments EL during diastole and EL-base during systole increased with severity of MR(P ＜0.05).The circulation during diastole also increased with the severity of MR(P ＜0.05).③The vortex area and circulation had positive correlation with E/e during diastole in all subjects(all P ＜0.05).The vortex area during atrial contraction period and early diastole had positive correlation with E/A and Tei index in all subjects(r =0.630,0.345,0.468,0.316,0.663,0.264,respectively,allP ＜0.01).EL-mid during late-systole were negatively correlated with LV end diastolic volume,end systolic volume,but positively correlated with ejection fraction in all subjects(r =0.335,-0.312,0.340,respectively,all P ＜0.05).While,there was positive correlation between E/A with the basal segment of mid-diastole(r =0.376,P ＜0.01).Conclusions The visualization of hydromechanics inside the heart of DCM patients could be directly accomplished by VFM,which can provide a new method for diagnosis and evaluation of DCM.

Objective:To evaluate arthrography-assisted reduction in minimally invasive treatment of tibial plateau fractures.Methods:From January to May 2019, 9 patients with tibial plateau fracture were treated by arthrography-assisted minimally invasive surgery at Department of Orthopaedics and Traumatology, Hong-Hui Hospital. They were 6 males and 3 females with an average age of 45.5 years (from 27 to 63 years). According to the Schatzker classification, there were 6 cases of type Ⅱ, one of type Ⅲ and 2 cases of type Ⅳ. Arthrography was used to determine the lowest filling point of contrast medium after intra-articular injection and to ensure satisfactory reduction of articular surface after fracture reduction and bone grafting, followed by minimally invasive percutaneous plate implantation. Comparisons were made between preoperation and 6 months postoperation in the range of knee motion and knee scores of The Hospital for Special Surgery (HSS). Knee X-ray films were evaluated by the Rasmussen imaging system at 6 months postoperation. Collapse of articular surface was recorded pre- and post-operation as well as postoperative complications.Results:All the 9 patients were followed up for 6 to 9 months (average, 7 months). All patients achieved bony union within 12 weeks postoperation. The preoperative knee flexion (60.7°±13.1°) and HSS (51.9±5.7) were significantly improved to 122.4°±10.8° and 84.9±5.3 at 6 months postoperation ( P<0.05), but there was no significant difference between preoperation and 6 months postoperation in knee extension (4.4°±2.5° versus 4.6°±2.9°) ( P>0.05). The collapse of articular surface was improved from preoperative 9.5 mm (from 5 to 15 mm) to postoperative 1.3 mm (from 0 to 3 mm). The Rasmussen imaging scores at 6 months postoperation showed 6 excellent and 3 good. No such postoperative complications occurred as incision infection, joint stiffness, loosening or breakage of implants. Conclusion:Arthrography helps minimally invasive treatment of tibial plateau fracture because it can better display fracture collapse during operation and accurately judge indirect reduction of articular surface.

Objective To understand the molecular aberration at whole genomic level,CGH (comparative genomic hybridization) was used to investigate genetic abnormality in lung cancer.Methods Comparative genomic hybridization was performed in 17 cases to detect the global genomic aberration in cancer tissue cells.Results All of 17 cases detected by CGH showed chromosomal aberrations.The average numbers of chromosomal gains and losses in each case were 7.0 and 4.8 in NSCLC and 8.4 and 9.6 in SCLC,respectively.The frequency of gains and losses on chromosome had no significant differences between NSCLC and SCLC.The frequencies of gains on chromosomal arms 3q24 -28 and 11q13(58.3％ and 58.3％ ) in NSCLC were significantly higher than that in SCLC(0％ and 0％ ) ( P ＜0.05 and ＜0.05,respectively).Conclusions The cytogenetic aberration generally existed in lung cancer cells.Several regions ( more than one) of chromosomal aberration were involved in the carcinogenesis of NSCLC and SCLC.The regions and frequencies of chromosomal aberration in NSCLC were somewhat different from that in SCLC,which might result in the different biological behavior of the two types of lung cancer.The chromosomal aberration might be served as a marker to differentiate the two types of lung cancer.

Objective To assess the value of color Doppler ultrasonogarphy in the diagnosis of subacute thyroiditis (SAT). Methods Sixty-eight patients of SAT and 30 patients with thyroid papillary carcinoma were included, and their imaging features were retrospectively reviewed. Results All the patients with SAT had either focal or diffuse hypoechogenicity of the thyroid lobes with rich blood supplying in the diseased region, among them 52 patients (76.47%, 52/68) had tenderness on palpation. Diffuse and focal lesions were found in 40 (58.82%, 40/68) and 28 patients (41.18%, 28/68). The boundary and shape of focal lesions had no diagnostic characteristics compared with those of thyroid papillary carcinoma. Punctate calcification and resistance index (RI) in the nodule were significant different between the SAT and thyroid papillary carcinoma (P＜0.05). Conclusion Color Doppler ultrasonography can display the features of SAT and is an effective method for the diagnosis of SAT.
