Objective: To investigate the clinical efficacy of fecal microbiota transplantation (FMT) for treating steroid-refractory gastrointestinal acute graft-versus-host disease (GI-aGVHD) . Methods: This analysis included 29 patients with hematology who developed steroid-refractory GI-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in Huaian Hospital Affiliated to Xuzhou Medical University from March 2017 to March 2022. Among them, 19 patients underwent FMT treatment (the FMT group) and 10 patients did not (the control group). The efficacy and safety of FMT were assessed, as well as the changes in intestinal microbiota abundance, lymphocyte subpopulation ratio, peripheral blood inflammatory cytokines, and GVHD biomarkers before and after FMT treatment. Results: ① Complete remission of clinical symptoms after FMT was achieved by 13 (68.4%) patients and 2 (20.0%) controls, with a statistically significant difference (P<0.05). Intestinal microbiota diversity increased and gradually recovered to normal levels after FMT and FMT-related infections did not occur. ②The proportion of CD3(+) and CD8(+) cells in the FMT group after treatment decreased compared with the control group, and the ratio of CD4(+), regulatory T cells (Treg), and CD4(+)/CD8(+) cells increased (all P< 0.05). The interleukin (IL) -6 concentration in the FMT group was lower than that in the control group [4.15 (1.91-5.71) ng/L vs 6.82 (2.40-8.91) ng/L, P=0.040], and the IL-10 concentration in the FMT group was higher than that in the control group [12.11 (5.69-20.36) ng/L vs 7.51 (4.10-9.58) ng/L, P=0.024]. Islet-derived protein 3α (REG3α) was significantly increased in patients with GI-aGVHD, and the REG3α level in the FMT group was lower than that in the control group after treatment [30.70 (10.50-105.00) μg/L vs 74.35 (33.50-139.50) μg/L, P=0.021]. Conclusion: FMT is a safe and effective method for the treatment of steroid-refractory GI-aGVHD by restoring intestinal microbiota diversity, regulating inflammatory cytokines, and upregulating Treg cells.

Objective: To explore the effects of bicycle ergometer rehabilitation training on quadriceps and walking ability of patients with lower limb dysfunction caused by extensive burns. Methods: A prospective randomized controlled study was conducted. A total of 40 patients with extensive burns who met the inclusion criteria and were admitted to Tongren Hospital of Wuhan University＆Wuhan Third Hospital from December 2017 to December 2020 were selected. According to the random number table, the patients were divided into conventional training group (16 males, 4 females, aged (45±10) years) and combined training group (13 males, 7 females, aged (39±8) years). Patients in conventional training group were given conventional rehabilitation therapy such as joint loosening, lower limb strength training, walking training, and pressure therapy, while patients in combined training group were given additional bicycle ergometer rehabilitation training on the basis of conventional rehabilitation. For patients in the 2 groups before and after a 2-month's treatment, the thickness of quadriceps was measured by ultrasonic diagnostic instrument, the muscle strength of quadriceps was measured by portable muscle strength tester, the walking ability was tested with a 6-min and a 10-meter walk tests, and the patients' satisfaction for treatment effects was assessed using the modified Likert scale. Data were statistically analyzed with independent or paired sample t test, Mann-Whitney U test, Wilcoxon signed rank test, or chi-square test. Results: After 2-month's treatment, the quadriceps thickness of patients in combined training group was (3.76±0.39) cm, which was significantly thicker than (3.45±0.35) cm in conventional training group (t=2.67, P<0.05); quadriceps thickness of patients in conventional training group and combined training group after 2-month's treatment was significantly thicker than that before treatment (with t values of 5.99 and 8.62, respectively, P<0.01). After 2-month's treatment, the quadriceps muscle strength of patients in combined training group was significantly greater than that in conventional training group (Z=2.69, P<0.01); quadriceps muscle strength of patients in conventional training group and combined training group after 2-month's treatment was significantly greater than that before treatment (with Z values of 3.92 and 3.92, respectively, P<0.01). After 2-month's treatment, the 6-min walking distance of patients in combined training group was (488±39) m, which was significantly longer than (429±25) m in conventional training group (t=5.66, P<0.01); the 6-min walking distance of patients after 2-month's treatment in conventional training group and combined training group was significantly longer than that before treatment (with t values of 13.16 and 17.92, respectively, P<0.01). After 2-month's treatment, the 10-meter walking time of patients in combined training group was significantly shorter than that in conventional training group (t=3.20, P<0.01); and the 10-meter walking time in conventional training group and combined training group was significantly shorter than that before treatment (with t values of 7.21 and 13.13, respectively, P<0.01). The patients' satisfaction score for treatment effects in combined training group was significantly higher than that in conventional training group (Z=3.14, P<0.01), and the patients' satisfaction scores for treatment effects in conventional training group and combined training group after 2-month's treatment were significantly greater than those before treatment (with Z values of 3.98 and 4.04, respectively, P<0.01). Conclusions: Bicycle ergometer rehabilitation training can be used to improve quadriceps thickness, muscle strength, and walking ability of patients with lower limb dysfunction caused by extensive burns. It can also improve the satisfaction of patients with the treatment outcome, and therefore is worthy of promotion.

Objective: To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD. Methods: The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD. Results: There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ). Conclusion The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.

OBJECTIVETo determine whether additional Chinese medicine (CM) could prolong survival and improve the quality of life (QOL) in patients with advanced non-small cell lung cancer (NSCLC) compared with Western medicine (WM) alone.

METHODSThis was a multicenter, prospective cohort study. A total of 474 hospitalized patients with stage III-IV NSCLC were recruited and divided into 2 groups. Patients in the WM group received radiotherapy, chemotherapy, and optimal supportive therapy according to the National Comprehensive Cancer Network (NCCN) guidelines. In the integrative medicine (IM) group, individualized CM (Chinese patent medicines and injections) and WM were administered. The primary end point was overall survival, and the secondary end points were time to disease progression, adverse events, and QOL. Follow-up clinical examinations and chest radiography were performed every 2 months.

RESULTSThe median survival was 16.60 months in the IM group and 13.13 months in the WM group (P<0.01). The incidences of loss of appetite, nausea, and vomiting in the IM group were significantly lower than those in the WM group (P<0.05). The QOL based on Functional Assessment of Cancer Therapy-Lung in the IM group was markedly higher than that in the WM group at the fourth course (P<0.05).

CONCLUSIONSAdditional CM may prolong survival and improve the QOL patients with NSCLC. The adverse effects of radio- and chemotherapy may be attenuated as CM is used in combination with conventional treatments.

Objective:To evaluate the clinical efficiency and prognostic factors of autologous peripheral blood stem cell trans-plantation (APBSCT) in 30 cases of multiple myeloma (MM). Methods:Two of the 30 patients received the second treatment of APB-SCT because of relapse after the first treatment. Thus, a total of 32 case-times of APBSCT were studied. Combination chemotherapy was inducted regularly before APBSCT (11 patients used bortezomib as an induction drug), and chemotherapy combined with the G-CSF regimen was used to mobilize peripheral blood stem cells. Preconditioning was based on melphalan. Results:Mononuclear cells in harvest were 6.41 × 108/kg, and CD34+cells in harvest were 4.75 × 106/kg. The median times of neutrophil and platelet engraftment were 9.5 and 11 d, respectively. The complete remission (CR) and very good partial remission (VGPR) rates were 37.5%and 34.4%af-ter APBSCT, respectively. The median overall survival (OS) was 67.27 months in all patients, and the median progression-free survival (PFS) was 29.77 months. The median PFS rates were 29 and 20 months in the patients who achieved CR and PR, respectively, and the median PFS was not observed in the patients who achieved VGPR. Statistical differences in PFS were detected between the CR+VGPR and PR groups (P=0.025). The CR rates were 63.6%and 23.8%in the bortezomib (bortezomib-based chemotherapy) and non-bortezo-mib groups (P=0.034), respectively. The median OS and PFS were not obtained in the bortezomib group, whereas the median PFS was 22 months in the non-bortezomib group (P=0.045). Conclusion: MM patients treated with bortezomib-based chemotherapy followed by APBSCT had prolonged PFS. APBSCT can improve the response and survival of MM patients.

OBJECTIVETo explore the clinical characteristics and prognostic value of monosomal karyotype (MK) patients in adult acute myeloid leukemia (AML).

METHODSWe retrospectively studied 45 patients of MK⁺ in newly-diagnosed adult AML in our center from Oct 2000 to Dec 2012. Clinical characteristics, cytogenetic data and prognostic features were analyzed in the cohort of MK⁺ patients.

RESULTSMK was found in 45 patients (19.0%) of 237 newly-diagnosed adult AML with cytogenetic data available at diagnoses. Among these 45 cases, there were 28 male (62.2%) and 17 female (37.8%). Median age of MK⁺ patients at diagnose was 58(18-91) years old. The presence of -5(31.1%) and -7(17.8%) were the most common chromatid among MK⁺ AML patients. MK was much more prevalent among elderly patients. Among AML patients, the proportions of MK⁺ patients younger than 30, 30 to 59 and older than 60 years old groups were 11.5%, 17.7% and 22.4%, respectively. There was no difference between MK⁺ and MK⁻ patients in gender distribution (P=0.545). There was also no difference between MK⁺ and MK⁻ patients in the distribution of FAB castigation (P=0.239). Median survival of MK⁺ AML patients was 6.5 months. Cumulative 5-year overall survival (OS) of was 5.2%. Forty-three MK⁺ patients (43/45, 95.6%) also had a complex karyotype (CK). Two cases that did not meet the CK had not achieved complete remission (CR), and died within 6 months. There were 12 patients who were CK⁺ in 192 MK⁻ patients. The differences of OS and CR rates between MK⁺CK⁺ patients and MK⁻CK⁺ were statistically significant (P<0.05).

CONCLUSIONThe increased detection rate of MK with age was associated with lower CR and OS in AML patients.

Objective To evaluate the outcome and safety of portable 3D head computed tomography (CT) navigation-guided keyhole microsurgery in patients with hypertensive intracranial hematomas (HICH).Methods Thirty-five consecutive unconscious patients with a volume of HICH at 24-90 mL,admitted to our hospital from January 2010 to December 2012,were treated with 3D image-guided keyhole microsurgery.The preoperative and postoperative neurological status determined by Glasgow Coma Scale (GCS) and modified Rankin Scale (mRS).Outcome at six months was assessed by Glasgow Outcome Scale (GOS).Results Average time from admission to the operation room,time for CT scan,and average operation time were (11.22±6.37) h and (19±13.11) min and (108.49±26.61)min,respectively.The total and near total (＞90％) hematoma evacuation rate was 96.9％.The mRS and GCS scores were significantly improved at discharge as compared with those before surgery (F=6.487,P＜0.05).Six months after the surgery,57.1％ patients achieved good recovery (GOS scores 4-5),and two patients died.Conclusion Keyhole minimally invasive hematoma with the help of portable head 3D reconstructed CT scan is highly effective in obtaining immediate and complete hematoma evacuation;portable CT is reliably and effective for preoperative navigation,and is very helpful for surgical management of patients with HICH.

OBJECTIVETo realize the influence of climatic changes on the transmission of hemorrhagic fever with renal syndrome (HFRS), and to explore the adoption of climatic factors in warning HFRS.

METHODSA total of 2171 cases of HFRS and the synchronous climatic data in Changsha from 2000 to 2009 were collected to a climate-based forecasting model for HFRS transmission. The Cochran-Armitage trend test was employed to explore the variation trend of the annual incidence of HFRS. Cross-correlations analysis was then adopted to assess the time-lag period between the climatic factors, including monthly average temperature, relative humidity, rainfall and Multivariate Elño-Southern Oscillation Index (MEI) and the monthly HFRS cases. Finally the time-series Poisson regression model was constructed to analyze the influence of different climatic factors on the HFRS transmission.

RESULTSThe annual incidence of HFRS in Changsha between 2000 - 2009 was 13.09/100 000 (755 cases), 9.92/100 000 (578 cases), 5.02/100 000 (294 cases), 2.55/100 000 (150 cases), 1.13/100 000 (67 cases), 1.16/100 000 (70 cases), 0.95/100 000 (58 cases), 1.40/100 000 (87 cases), 0.75/100 000 (47 cases) and 1.02/100 000 (65 cases), respectively. The incidence showed a decline during these years (Z = -5.78, P < 0.01). The results of Poisson regression model indicated that the monthly average temperature (18.00°C, r = 0.26, P < 0.01, 1-month lag period; IRR = 1.02, 95%CI: 1.00 - 1.03, P < 0.01), relative humidity (75.50%, r = 0.62, P < 0.01, 3-month lag period; IRR = 1.03, 95%CI: 1.02 - 1.04, P < 0.01), rainfall (112.40 mm, r = 0.25, P < 0.01, 6-month lag period; IRR = 1.01, 95CI: 1.01 - 1.02, P = 0.02), and MEI (r = 0.31, P < 0.01, 3-month lag period; IRR = 0.77, 95CI: 0.67 - 0.88, P < 0.01) were closely associated with monthly HFRS cases (18.10 cases).

CONCLUSIONClimate factors significantly influence the incidence of HFRS. If the influence of variable-autocorrelation, seasonality, and long-term trend were controlled, the accuracy of forecasting by the time-series Poisson regression model in Changsha would be comparatively high, and we could forecast the incidence of HFRS in advance.

Objective To analyze the spatio-temporal process on 2009 influenza A (HlNl) pandemic in Changsha and the influencing factors during the diffusion process. Methods Data were from the following 5 sources, influenza A (HlNl) pandemic gathered in 2009, Geographic Information System (GIS) of Changsha, the broad range of theorems and techniques of hot spot analysis, spatio-temporal process analysis and Spearman correlation analysis. Results Hot spot areas appeared to be more in the economically developed areas, such as cities and townships. The cluster of spatial-temporal distribution of influenza A (HlNl) pandemic was most likely appearing in Liuyang city (RR=22.70,P<0.01). The secondary cluster would include districts as Yuelu (RR=6A9,P< 0.01) , Yuhua (RR=81.63, P<0.01). Xingsha township appeared as the center in the Changsha county (RR=2.90, P<0.01) while townships as Yutangping (RR=19.31, P<0.01) , Chengjiao (RR=73.14,P<0.01) and Longtian appeared as the center in the west of Ningxiang county (RR= 14.43,P<0.01) and Wushan as the center in the Wangcheng county (RR= 13.84,P<0.01). As time went on, the epidemic moved towards the eastern and more developed regions. Regarding factor analysis, population, the amount of students, geographic relationship and business activities etc. appeared to be the key elements influencing the transmission of influenza A (H1N1) pandemic. At the beginning of the epidemic, population density served as the main factor (r=0.477, P<0.05) but during the initial and fast growing stages, it was replaced by the size of students to serve as the important indicator (r=0.831, P<0.01; r=0.518, P<0.01). However, during the peak of the epidemics, the business activities played an important role (r=-0.676, P<0.01). Conclusion Groups under high risk and districts with high incidence rates were shifting, along with the temporal process of influenza A(H1N1) pandemic, suggesting that the protection measures need to be adjusted, according to the significance of influencing factors at different stages.
