[Objective]To investigate the treatment of fractuees of distal end of humerus with open reduction and internal fixation with anatomical plate.[Method]From February 2001 to April 2006,open reduction and anatomical plate internal fixation were performed in 22 cases with distal end of humerus fracture,of which olecranon osteotomy approach was carried out in 11 while musculus triceps brachii linguiform flap approach in other 11.All the patients received combined therapy including fumigation and rinsing with Chinese herbs,CPM(continuous passive motion) and manipulation.[Result]All the cases were followed up for 13 to 22 months.All the fractures got union.The postoperative elbow functions were excellent in 9 cases,good in 7 cases according to Mayo standards.The satisfactory rate was 72.71%.[Conclusion]Open reduction and internal fixation with anatomical plate can provide stable fixation and allow early postoperative elbow functional training in treatment of distal humerua fracture.Good clinical results can be achieved using fumigation and rinsing with Chinese herbs,CPM and manipulation after operation.

Enhanced green fluorescent protein( EGFP), myc epitope and polyhistidine metal-binding tag are often used as a marker for recombinant fusion protein in many gene expression vectors, each marker has its own function, EGFP emits green fluorescence for direct detection, myc epitope facilitates recombinant fusion protein detection using its antibodies, polyhistidine tag allows purification of recombinant fusion protein using resin.Hitherto, no a plasmid vector can integrate all of these functions. In this study we constructed a novel eukaryotic expressive plasmid, designated as pcDNA6/myc-his-EGFP B, which integrated the functions of EGFP, myc epitope and polyhistidine tag. Importantly, a linker octo - peptide in N terminal of EGFP was designed using LINKER program. A DNA fragment encoding a putative protein containing a signal peptide of human interleukin 2(IL-2) in N terminal was cloned into pcDNA6/myc-his-EGFP B in frame with the C-terminal peptide to construct pMHES. 2.2.15 Cells were transfected with pcDNA6/myc-his-EGFP B and pMHES, and Balb/c mice were intravenously injected with pcDNA6/myc-his-EGFP B by tails, results revealed that both of the plasmids worked in 2.2.15 Cells and livers of Balb/c mice. Assuming gene of the IL-2 was inserted into pcDNA6/myc-his -EGFP B in frame with EGFP, myc and 6 × His, three-dimensional structure for this putative expression product was simulated using Modeller8V2, results revealed that IL-2, EGFP, myc and 6 × his did not interfere each other and octo- peptide linker owned certain flexibility. The results suggest that pcDNA6/myc-his-EGFP B may be useful as a genetic tool for mammalian cells and a vector for gene therapy.

Objective To develop a real-time QRS complex detection algorithm of dynamic ECG signals for the GPRS mobile telemonitoring system. Methods Before the first and second derivatives of ambulatory ECG signals were processed by moving average method, the signals sampled from CM5 monitoring lead were filtered with the average of continuous four ECG sample signal points. The R waves could be detected precisely by local minima of second derivatives and Q & S waves were located correctly by cross-zero points of first derivatives of ambulatory ECG signals in a short-time searching windows. The QRS recognition thresholds, which could revise themselves according to the detected values and vary with the analyzing signals, were designed in this paper. Results With a polynomial computation complexity, the novel algorithm insensitive to baseline draft and noise caused by mobile communication filtered power-line interference and most of muscle noise and reduced the search time below 0.02 s during detecting each Q wave, R wave and S wave. For the normal and clinical patients, this algorithm correctly detected up to 99.8% of the QRS complex of ambulatory ECG signals. Conclusion The algorithm can meet the need of real-time QRS complex detection and analysis for the GRRS mobile ECG telemonitoring system.

Objective: To explore the effect of Dahuang-Zhidan decoction on postoperative peripheral inflammatory factors and prognosis in patients with hypertensive cerebral hemorrhage. Methods: A total of 103 patients with hypertensive cerebral hemorrhage in our hospital from May 2015 to January 2017 were divided into two groups according to the randomly number tables method. The control group (n=51) were treated by conventional treatment of western medicine, and the observation group (n=52) were treated with Dahuang-Zhidan decoction based on the treatment of the control group.The inflammatory factors, including interleukin-6 (IL-6), tumor necrosis factor (TNF-α), highly sensitive C-reactive protein (hs-CRP), interleukin-1β (IL-1β) in hematoma lesions after treatment for 1st, 7th day between two groups were measured. The comparisons of awake rate after treatment for the 7th, 14th, 30th day between two groups was conducted. The National Institute of Health Stroke Scale (NIHSS) scores after treatment for 30th, 90th day between two groups was launched. The Glasgow Prognosis Score (GOS) between two groups was compared at the 90th day. Results: After treatment for 7 d,the postoperative peripheral inflammatory factors IL-6 (90.55 ± 18.89 pg/ml vs. 122.71 ± 19.62 pg/ml, t=-6.892), TNF-α (172.26 ± 29.85 pg/ml vs. 229.02 ± 30.34 pg/ml, t=-10.332), hs-CRP (137.55 ± 24.60 pg/ml vs. 162.14 ± 23.98 pg/ml, t=-8.615), IL-1β (95.57 ± 18.92 pg/ml vs. 110.65 ± 17.38 pg/ml, t=-3.594) in the observation group was significantly lower than those in the control group (P<0.05). After treatment for 7, 14, 30 d, the awake rate was 44.23% (23/52), 69.23% (36/52), 90.38% (47/52) in the observation group, which was significantly higher than those in the control group (χ²=3.977, 4.355, 4.499, P<0.05). After treatment for 30, 90 d, the NIHSS scores (12.24 ± 6.38 vs. 16.27 ± 7.69, t=-2.906), (5.39 ± 6.24 vs. 9.94 ± 8.11 , t=-3.198) in the observation group were significantly lower than those in the control group (P<0.05). After treatment for 90 d, the distribution of GOS scores in the observation group was significantly different from the control group (Z=-2.400, P=0.016). Conclusions The Dahuang-Zhidan decoction in the treatment of patients with hypertensive cerebral hemorrhage significantly inhibit postoperative the inflammatory response around hematoma lesions, and improve the neurological function, the awake rate and the qualify of life.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.
