Objective:To analyze the clinical features and laboratory indicators in patients with solid malignant tumor-associated venous thromboembolism(Ta-VTE),and to study the risk factors for Ta-VTE.Methods:The hospitalized patients with VTE in Guizhou Provincial People's Hospital from January to December 2020 were enrolled,and they were divided into Ta-VTE group and pure VTE group based on the presence or absence of solid malignant tumor.The differences in clinical data and laboratory indicators between the two groups were analyzed,and the indicators with significant differences were included in logistic regression model to analyze the risk factors of Ta-VTE.Results:A total of 288 patients with VTE were included in this study,including 64 cases in Ta-VTE group and 224 cases in pure VTE group,respectively.There were significant differences in the following indexes between the two groups,including the hospitalization time(14.20±15.29 d vs 10.05±6.90 d,t=3.112,P=0.002),pain(35.94％vs 65.18％,x2=17.554,P=0.000),recent surgery(75.00％vs 37.50％,X2=28.196,P=0.000),D-dimer[2.8(0.92,7.55)μg/ml vs 5.69(2.25,13.91)μg/ml,Z=-2.710,P=0.007],PLR[198.59(139.54,312.16)vs 149.76(114.08,233.66),Z=-2.924,P=0.003]and TBIL[10.90(7.63,15.68)μmol/Lvs 12.90(9.33,18.28)μmol/L,Z=-2.066,P=0.039].There was no significant difference in the other indicators(P＞0.05).The result of multivariate logistic regression analysis showed that elevated PLR(OR=1.003,95％CI:1.000-1.006,P=0.027),recent surgery(OR=4.312,95％CI:2.093-8.885,P=0.000)and prolonged hospitalization(OR=1.037,95％CI:1.002-1.074,P=0.038)were independent risk factors for Ta-VTE.However,pain(OR=0.274,95％CI:0.133-0.564,P=0.000)was a protective factor.Conclusion:Elevated PLR level,recent surgery and prolonged hospital stay are independent risk factors for Ta-VTE patients,and rational use of these indicators is helpful for the clinical diagnosis and treatment of Ta-VTE patients.

OBJECTIVE: To retrospectively study medium term follow up outcomes effects of effect of bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients. METHODS: Total of 32 elderly patients with the osteoporotic intertrochanteric fractures were treated with bio-lengthend stem hemiarthroplasty from Jan. 2016 to Jan. 2019 including 14 males and 22 females, aged from 85 to 95 years old with an average of (89.5±4.5) years old. According to classification of Evans, there were 12 cases with type Ⅲ, 11 with type Ⅳ and 9 with type Ⅳ. The time from injury to operation ranged from 0.5 to 9 days with an average of (4.5±3.9) days. The operation time, blood loss and postoperative complications were analyzed. Functional outcome was assessed by Parker Palmer mobility score(PPMS) and Harris hip score. RESULTS: Four patients died within one year after operation, and the mortality was 12.5%. The follow up time for the rest 28 patients ranged from 24 to 60 months with an average of (28.5±4.5) months. The mean operative time was (54.2±22.5) min;the mean blood loss (hidden blood loss+obvious blood loss) was (450±140) ml;the first weight bearing was (3.35±1.35) days. No perioperative death occurred. PPMS were(6.63±1.25), (6.94±1.18), (7.11±0.83), (7.32±1.11) and Harris scores were(67.85±6.19), (71.42±5.57), (73.41±5.62), (77.32±5.24) respectively at 1, 3, 6 months and the final follow-up after operation. There were no significant difference in PPMS and Harris score at 1, 3, 6 months after operation and the final follow-up(P>0.05). There were no complications such as joint dislocation and prosthesis loosening occure at the final follow-up. CONCLUSION On the premise of strictly mastering the case selection criteria, the bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients has a satisfied medium term follow-up outcomes. It can restore hip function in the early stage and improve the quality of life of patients.

Objective:To evaluate the hemostatic effects of our self-designed pelvic band with inflatable balloon in a swine model of hemodynamically unstable pelvic fracture.Methods:"Open-book like" fractures were created with the external iliac blood vessels exposed in 24 12-month-old female Bama miniature pigs which were randomly divided into 4 groups ( n=6). Group C (the control group) was subjected to no treatment other than exposure of the external iliac blood vessels, group D to no treatment following destruction of the external iliac blood vessels, group T1 to fixation with simple pelvic band after destruction of the external iliac blood vessels, and group T2 to fixation with our self-designed pelvic band with inflatable balloon after destruction of the external iliac blood vessels. The 4 groups were compared in terms of 40-min survival rate, bladder pressure, peak lactate value, total blood loss, bleeding rate, infusion rate, and angiographic images. Results:There was no significant difference in the baseline indexes among the 4 groups before experiment, showing comparability ( P>0.05). The 40-min survival rate in group T2 was 83.3% (5/6), significantly higher than that in groups D and T1 [0% (0/6) and 0% (0/6)] ( P<0.05). There were no significant differences among groups C, D, T1 and T2 in bladder pressure [(6.67±1.03) mmHg, (5.83±1.94) mmHg, (6.00±1.55) mmHg, and (6.00±1.10) mmHg] or in total blood loss among groups D, T1 and T2[(1,198.0±182.9) mL, (1,252.0±148.4) mL, and (1,150.0±125.7) mL] (all P>0.05). The peak lactate value in group T2 [(2.26±0.24) mmol/L] was significantly lower than that in group D [(5.00±0.60) mmol/L] and group T1 [(3.86±0.57) mmol/L], and the bleeding rate and infusion rate in group T2 [(25.83±5.49) mL/min and (26.00±4.69) mL/min] were also significantly lower than those in group D [(83.50±19.85) mL/min and (71.50±29.11) mL/min] and group T1 [(54.17±15.59) mL/min and (54.17±8.98) mL/min] (all P<0.05). Angiography showed contrast agent extravasation in group T2, especially from the artery, but the extravasation speed in group T2 was significantly slower than that in group D. Conclusion:In a swine model of hemodynamically unstable pelvic fracture, our self-designed pelvic band with inflatable balloon has a definite hemostatic effect on vascular injury which is better than that of a simple pelvic band.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

BACKGROUND: Self-healing ability of the posterior cruciate ligament is poor, and the degradation and synthesis of extracellular matrix often follow the ligament repair. The matrix metalloproteinase family plays a critical role in the dynamic equilibrium between the matrix degradation and synthesis. OBJECTIVE: To investigate the effect of arthroscopic reconstruction of the posterior cruciate ligament, and to study its correlation with matrix metalloproteinase 2 level. METHODS: Sixty patients with posterior cruciate ligament rupture were studied, including 37 cases of autologous reconstruction and 13 cases of allogeneic reconstruction. Ligament and synovial cells from traumatic amputation patients with no ligament injury in the corresponding period were collected. Lysholm and Tegner scores were detected before and after operation. The results of postoperative drawer test were analyzed. The tibial displacement of the posterior cruciate ligament after autologous reconstruction and allogeneic reconstruction was compared. The posterior cruciate ligament cells were cultured alone or co-cultured with synovial cells, and then the level of matrix metalloproteinase 2 protein was detected. In addition, operation time, incision length, postoperative fever time and gender differences were also detected and compared.RESULTS AND CONCLUSION: Tibial displacement, irrespective of genders, was higher in the allogeneic reconstruction group than the autologous reconstruction group, while there were no significant differences in the posterior drawer test between the two reconstruction groups as well as between males and females. Postoperative Lysholm and Tegner scores were both improved significantly (P < 0.01). As time went by, the level of matrix metalloproteinase 2 had an increasing trend in the posterior cruciate ligament cells cultured alone or co-cultured with synovial cells, but the level in the co-culture group was higher than that in the single culture group. For both male and female, the autologous reconstruction group showed a longer operative time (P < 0.05 or 0.01) and a longer incision length (P < 0.01), as compared with the allogeneic reconstruction group, while the time of fever was significantly longer in the allogeneic reconstruction group (P < 0.01). Results from the last follow-up show that the autologous reconstruction is better than the allogeneic reconstruction to restore the stability of posterior cruciate ligament and shorten fever time, but longer operative time and surgical incision as well as increased level of matrix metalloproteinase 2 cannot be ignored.

Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG).However,the dynamic process and mechanism of fluorescenceIOC have not been elucidated in previous publications.Herein,the optical properties of the complex of ICG and bile,dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated.The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration.Extrahepatic bile ducts could fluoresce 2 min after intravenous injection,and the fluorescence intensity reached a peak at 8 min.Inaddition,biliary dynamics were observed owing to ICG excretion from the bile ducts into the duodenum.Quantitative analysis indicated that ICG-guided fluorescence IOC possessed a high signal to noise ratio compared to the surrounding peripheral tissue and the portal vein.Fluorescence IOC was based on rapid uptake of circulating ICG in plasma by hepatic cells,excretion of ICG into the bile and then its interaction with protein molecules in the bile.Moreover,fluorescence IOC was sensitive to detect bile duct ligation and acute bile duct perforation using ICG in rat models.All of the results indicated that fluorescence IOC using ICG is a valid alternative for the cholangiography of extrahepatic bile ducts and has potential for measurement of biliary dynamics.
