ABSTRACT

Objective:To investigate the manifestations of liver injury in hospitalized patients with coronavirus disease 2019 (COVID-19), to investigate the prognosis indicators of the disease, and to provide the reference for clinical diagnosis and treatment.Methods:From January 10 to February 14, 2020, at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, the data of 333 hospitalized patients with COVID-19 were collected. The changes of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), direct bilirubin (DBil), indirect bilirubin (IBil) and albumin of the first liver function test after admission and the reexaminations of liver function test during hospitalization period in patients with liver injury were retrospectively analyzed. Student t test and Chi-square test were used for statistical analysis. Results:Liver injury occurred in 39.6% (132/333) of COVID-19 patients. There was no statistically significant difference in the rate of liver injury between patients in intensive care unit (ICU) and in general ward (45.6%, 26/57 vs. 38.4%, 106/276; χ2=1.026, P>0.05). 67.4% (89/132) of COVID-19 patients with liver injury presented with increased ALT or AST level on admission. During hospitalization, the level of ALT was higher than that of the first examination after admission ((60.28±50.44) U/L vs. (42.25±32.21) U/L), and the difference was statistically significant ( t=-3.230, P<0.05). The levels of ALT and AST of 71.2% (94/132) patients were both <80 U/L, which indicated that most of the patients showed mild liver injury. The patients with elevated level of TBil, DBil and IBil accounted for 3.9% (13/333), 5.4% (18/333) and 2.4% (8/333) of the COVID-19 patients, respectively. The albumin level of COVID-19 patients with liver injury during hospitalization was lower than that of the first examination after admission ((31.8±5.1) g/L vs. (33.7±5.4) g/L), and the difference was statistically significant ( t=2.712, P<0.05). The albumin levels at first examination on admission and reexamination during hospitalization of patients in ICU were both significantly lower than those of patients in general ward ((29.3±3.7) g/L vs. (34.8±5.1) g/L and (27.6±2.8) g/L vs. (32.9±5.1) g/L), and the differences were statistically significant ( t=4.928 and 4.783, both P<0.05). Conclusions:The incidence of liver injury in COVID-19 patients is high. A slight increase in aminotransferase levels is particularly common. Bilirubin abnormality is relatively rare and mild. The level of albumin may be one of the indicators for the severity and prognosis of COVID-19.

ABSTRACT

Objective: To explore the effect of differentiation of cardiac stem cells (CSC) mediated by pilose antler polypeptides on the expressions of terminal myocardial differentiation genes atrial natriuretic polypeptide (ANP) and myosin light chain 2v (MLC-2v), and to clarify the mechanism of repairing the damaged myocardium Methods: The healthy male Wistar rats born 2 d were selected to extract the CSC. The surface marker c-Kit and the purity of CSC were identified by immunofluorescence and flow cytometry. The culture dish was used as the experimental unit and the extracted cells were divided into the following four groups: blank control group (the same amount of buffer was added for induction), 5-azacytidine group (induced with 3 jumol · L-1 5-azacytidine), pilose antler polypeptides group (induced with 800 mg · L-1 pilose antler polypeptides) and combined group (induced with 800 mg · L-1 pilose antler polypeptides and 3 μmol · L-1 5-azacytidine); the cells were incubated for 48 h in the condition of 37°C and 5% CO2. The expression levels of ANP and MLC-2v in supernatant of the cells in various groups were detected by ELISA method. The expression levels of ANP and MLC-2v mRNA in the cells in various groups were detected by RT-PCR method. Results: CSC were prepared with the purity0.05). The result of RT-PCR showed that the expression levels of ANP and MLC-2v mRNA in 5-azacytidine, pilose antler polypeptides and combined groups were significantly increased compared with blank control group (P<0.05). Conclusion: Pilose antler polypeptides can induce the differentiation of CSC into cardiac cells by promoting the expressions of ANP and MLC-2v, and they can reduce the cytotoxicity induced by 5-azacytidine in some degrees.

ABSTRACT

Objective To investigate the rate of termination of pregnancy (TOP) in gravidas with prenatally diagnosed fetal malformation and to analyze the influences of medical and non-medical factors on decision making.Methods This was a prospective cohort study. Gravidas who took part in a multidisciplinary consultation due to fetal malformation and finished a questionnaire after consulting from September 12, 2012 to May 2, 2013 were recruited. Exclusion criteria were chromosomal disorders and isolated abnormal ultrasound soft markers. The questionnaire survey was conducted to understand the patient's backgrounds and to collect their feedbacks on the consultation. Decisions of the gravidas on TOP were followed up by phone in 2014 and 2016. If a gravida chose to continue her pregnancy, her baby's outcome was also recorded.T test,Chi-square test or Fisher's exact test, or rank-sum tests (Mann-Whitney or Wilcoxon) or Logistic regression was used for statistical analysis.Results (1) Altogether 229 gravidas were recruited and 10 of them were lost to follow-up, so 219 cases were finally analyzed. Among the 219 cases, 35.6% (78/219) chose to terminate their pregnancies. (2) Neonatal prognosis was predicted based on the type and severity of the disease and was divided into four levels including good prognosis (122 cases, 55.7%), medium prognosis (20 cases, 9.1%), poor prognosis (17 cases, 7.8%) and unsure prognosis (60 cases, 27.4%). (3) Gravidas who chose to terminate their pregnancies were younger than their counterparts choosing to continue to term (average age: 27.8±4.1 vs 29.0±3.9,t=2.257,P<0.05). Gravidas who went to the consultation before the 24th gestational week carried double risk of TOP than those after the 24th gestational week [termination rate: 52.5% (31/59) vs 29.4% (47/160),χ2=10.089,P<0.01). (4) Gravidas with fetal growth restriction (FGR) were at triple risk of TOP than those without (OR=2.850, 95%CI: 1.323-6.140) after adjusting for maternal age, gestational age at consultation and prognostic evaluation. Comparing with the good prognosis group, in which the rate of TOP was 19%, the unsure (OR=2.354, 95%CI: 1.108-5.004), medium (OR=16.188, 95%CI: 4.732-55.372) and poor (OR=14.515, 95%CI: 3.61-58.359) prognosis groups had higher risk of TOP. (5) There were 63 women informed us their reasons for TOP (multiple choices), among which 57 (90.5%) were due to unsure neonatal outcomes, and 10 (15.9%) were due to emotional factors. (6) Maternal satisfaction with neonatal prognosis was 2 to 5 points (medium score, ten-point system) lower in gravidas choosing to TOP than in those choosing to continue pregnancy regardless of good, unsure, or medium neonatal prognosis. No significant difference in maternal satisfaction was found among gravidas with poor neonatal prognosis.Conclusions The rate of TOP in gravidas with prenatally diagnosed fetal malformation remains high in China. Factors that can negatively influence the rate of TOP are consultation after the 24th gestational week, better perceived neonatal prognosis and higher maternal satisfaction with neonatal prognosis. Uncertainty of the neonatal prognosis is the leading cause of maternal dissatisfaction.

ABSTRACT

BACKGROUND: Cardiac stem cells can differentiate into cardiomyocytes in vitro under induction of pilose antlerpolypeptides, which provides a new therapeutic idea for myocardial injury.OBJECTIVE: To explore the effect of pilose antler polypeptides on the apoptosis rate and membrane stability ofmitochondria in cardiac stem cells.METHODS: We chose healthy male Wistar rats born 2 days to extract cardiac stem cells. The culture dish was used asthe experimental unit, and extracted cells were divided into the following four groups (n=12). Blank control group: Thesame amount of buffer was added for induction; 5-azacytidine group: induced with 5-azacytidine (3 μmol/L); pilose antlerpolypeptides group: induced with pilose antler polypeptides (800 mg/L); combined group: induced with pilose antlerpolypeptides (800 mg/L) and 5-azacytidine (3 μmol/L). After 48 hours induction, apoptosis rate of cardiac stem cells ineach group was detected with flow cytometry. The membrane potential of mitochondria in cardiac stem cells wasdetected with immunofluorescence. The expression level of Nkx 2.5, GATA4, ATF-2, and MEF-2C in cardiac stem cellswas detected using western blot assay.RESULTS AND CONCLUSION: There were small, round and bright cells after 2 weeks culture, and cell colonies ofcardiac stem cells formed. The apoptosis rate of cardiac stem cells in the 5-azacytidine group increased significantly (P 0.05). The expression level of MEF-2C in each group was at a middle level, and there were no significantdifferences among groups (P > 0.05). To conclude, our experimental findings indicate that pilose antler polypeptidescould decrease the apoptosis rate and improve membrane stability of mitochondria in cardiac stem cells. Themechanism may be related to the increased expression of Nkx 2.5, but whether the mechanism is related to GATA4,ATF-2 and MEF-2C needs to be further studied.

ABSTRACT

BACKGROUND: Compared with the metal screws, absorbable screws have more obvious advantages, such as does not have to conduct internal fixation removal, non-metal ic components, no influence on the magnetic resonance imaging of patients after implantation, relatively simple operations, namely dril ing-tapping-screws fixation, more in line with the principles of minimal y invasive in orthopedics. OBJECTIVE: To investigate the biomechanical characteristics of absorbable screw fixation in repair of simple lateral mal eolus fractures by means of finite element technology. METHODS: The three-dimensional model of simple lateral mal eolus fractures and absorbable screw model were established, and then fixed according to standard orthopedic surgical techniques. The reference load when the load bearing of fibulotalar joint reaching the peak value in a normal adult gait cycle was loaded. The stress distribution and displacement of fibula and absorbable screws were analyzed. RESULTS AND CONCLUSION: There were total y 38 542 units, 8 790 nodes in the single screw fixation model. When the articular facet of lateral mal eolus loading 300 N, the maximum stress of screws was 89.35 MPa, the maximum displacement was 0.5 mm, the maximum displacement of the distal fracture was 0.5 mm. When the articular facet of lateral mal eolus loading 450 N, the maximum stress of screws was 152.58 MPa, the maximum displacement was 0.59 mm, the maximum displacement of the distal fracture was 0.77 mm. There were total y 43 115 units, 9 496 nodes in the double screws fixation model. When the articular facet of lateral mal eolus loading 300 N, the maximum stress of screws was 38 MPa, the maximum displacement was 0.44 mm, the maximum displacement of the distal fracture was 0.44 mm. When the articular facet of lateral mal eolus loading 450 N, the maximum stress of screws was 66.68 MPa, the maximum displacement was 0.48 mm, the maximum displacement of the distal fracture was 0.49 mm. The experiment verified the biomechanical feasibility of absorbable screw fixation in repair of simple lateral mal eolus fractures. For simple involving only the lower lateral fibular fracture, absorbable screw fixation is entirely feasible, and usual y requires at least two screws to maintain the stability of the articular surface of the reset.

ABSTRACT

BACKGROUND:For unstable intertrochanteric fracture repair, there are two views:extramedul ary fixation or intramedul ary fixation. Theoretical y, intramedul ary fixation is in line with the principles of minimal y invasive, more mechanical and biological advantages. However, evidence-based medicine and related studies have shown that compared with the extramedul ary fixation, intramedul ary fixation did not reflect the proper theoretical advantage. OBJECTIVE:To compare the biomechanical performance of two kinds of internal fixation systems:dynamic hip screw and Gamma nail which commonly used in repair of intertrochanteric fractures by finite element method, and to evaluate the advantages and disadvantages of dynamic hip screw and Gamma nail in treatment of unstable intertrochanteric fracture. METHODS:Three-dimensional finite element model of human femur unstable intertrochanteric fractures (31-A2;AO fracture classification), and the three-dimensional finite element models of dynamic hip screw and Gamma nail were established respectively, and were fixed according to the requirement of orthopedic surgery. The reference load which the joint bearing was at the peak time in adult step state period with the body mass of 700 N was stimulated. The stress distribution of bone, bone-internal fixation model, nail or screw, the strain and deformation of fracture location on the surface of the bone and bone-internal fixation model, the stress distribution along the femur and the loading transfer condition along the internal fixator and the like were analyzed. RESULTS AND CONCLUSION:Dynamic hip screw and Gamma nail have good sliding compression features which could make the continuous and dynamical y axial compression of the fractured section. Under the load conditions, the displacement value of dynamic hip screw was larger. In the treatment of unstable intertrochanteric fracture, Gamma nail was stronger than dynamic hip screw. Two kinds of internal fixations al make the bearing load of the proximal femur reduce. In the treatment of 31-A2 type unstable intertrochanteric fractures, we should choose dynamic hip screw for fixation if the femoral calcar was not seriously crushed, little defect or no defects and can immediately rebuild the stability of femoral calcar during operation, otherwise, stronger internal fixation, namely Gamma nail fixation should be chosen.

ABSTRACT

Objective To investigate the clinical features and mechanism and feasibility of plasma exchange (PE) in treating systemic lupus erythematosus (SLE) complicated with acute pancreatitis (AP). Methods A retrospective analysis of SLE associated with AP was done based on the HIS in Tongji Hospital. Totally 24 SLEAP patients were admitted to Tongji hospital from March 2006 to May 2014. Patientsˊ serum amylase, lipase and interleukin (IL)-6 concentration were measured before and after plasma exchange. According to different therapy strategy, patients were divided into two groups. Fifteen patients treated with plasma exchange combination with glucocorticosteroid (GC) were classified as Group A, the other 9 patients who were treated with GC only were classified as group B. At baseline and after treatment, the serum lipid concentration, average daily glucocorticosteroid dosage between group A and B were compared with ANOVA and serum IL-6 concentration between roup A and B were compared with Wilcoxon rank test. Results SLEDAI score in group A patients at baseline (16 ±5) was no statistically different from that in group B (18 ±4) (t=1.31, P=0.320). Average daily GC dosage in group A 31.0 (20.50, 30.08)mg/d was significantly less than that in group B 47.85 (45.58, 59.23) mg/d (Z=35.50, P= 0.002). Serum IL-6 levels in group A and B at baseline was not significantly different 13.14 (11.12,16.57) mg/L vs 14.63 (11.37, 16.37) mg/L (Z=12.20, P=0.300), after 2 weeks treatment, IL-6 level, which was 9.16 (7.93, 10.75) mg/L, decreased significantly in group A while it didnˊt show tendency of decrease in group B, which was 13.62(9.29, 17.63) mg/L (Z=28.50, P=0.039). Serum lipid concentration after 2 weeks therapy in Group A [TC=(5.02 ±0.53) mmol/L, TG=(1.46 ±0.44) mmol/L] decreased significantly compared to baseline [TC=(6.11±0.50) mmol/L, TG=(2.14±0.65) mmol/L] (F=4.46, P=0.010; F=6.09, P=0.002), while similar tendency wasnˊt observed in group B (F=1.57, P>0.05). Conclusion PE combined with GC could lower serum IL-6 levels, reduce the amount of GC and lower serum lipid to improve prognosis. Therefore it might be a safe and effective way and is worthy of continuing to explore its feasibility.

ABSTRACT

Objective:To establish the quality standard for Chuipencao tablets. Methods:Sedum sarmentosum Bunge was identi-fied by TLC. Quercetin, kaempferol and isorhamnetin were determined by HPLC. Results: The method of TLC was highly specific. The linearity was obtained within the range of 4.94-98.82 μg·ml-1(r =0.999 9) for quercetion, 4.94-98.82 μg·ml-1(r =0.999 9) for kaempferol and 1.07-21.36 μg·ml-1(r=0.999 9) for isorhamnetion. The average recovery was 103.1%(RSD =2. 2%,n=6), 100. 6%(RSD=2. 0%,n=6) and 100. 1%(RSD=2. 0%,n=6), respectively. Conclusion: The method is accu-rate with good reproducibility, which can be used as the quality control for Chuipencao tablets.

ABSTRACT

Background and purpose:More than 70 percent of ovarian cancer patients were diagnosed in the advanced stage. Currently the 5-year disease free survival (DFS) of stageⅢC-Ⅳovarian cancer patients wsa about 10 percent after first line chemotherapy. This study aimed to improve the 5-year DFS by three-step chemotherapy according to the mechanisms of ovarian cancer biological characteristics, cytodynamics and pharmacology. Methods:In arm A, the patients received three-step chemotherapy after primary debulking surgery, step one with paclitaxel plus carboplatin (TC regimen), every 3 weeks for 6 to 8 cycles;step two with etoposide plus cyclophosphamide, every 4 weeks for 6 cycles;step three wit carboplatin plus cyclophosphamide every eight weeks for six cycles. In control arm B, we retrospectively analysed 51 cases withⅢC-Ⅳstage ovarian cancer, who had completely response after standard chemotherapy with six to eight cycles of TC after primary surgery during 2007. We compared the 5-year DFS between the two arms. Results:The 5-year DFS of 15 cases in arm A was 80%(12/15), which was signiifcantly higher than that of arm B (5.9%, 3/51, P<0.01). Conclusion: The three-step chemotherapy after optimal debulking surgery in stageⅢC-Ⅳ can improve the 5-year DFS. This regimen is high efficacy, mild side-effect witn low cost, which deserves further exploration.

ABSTRACT

Objective To establish the reference ranges for fetal cardiac axis in the mid-second trimester and to evaluate the use of fetal cardiac axis in prenatal diagnosis.Methods 6744 unselected singleton pregnancies were enrolled from September 2008 to October 2010.Routine screening scan of second trimester and fetal echocardiography were performed at 18- 23+6 weeks gestation.Fetal cardiac axis was measured on the four-chamber view of the heart.Results The 6744 fetuses had a mean cardiac axis of (37.03 ± 6.10)°,ranging from 9.80° to 102.41°. Using above or below 95% range of population (26.63° -49.40°) as a cut-off,there were significant difference of cardiac axis between normal group [(36.96 ± 5.91)°,P <0.01] and the group with heart defects [(43.12 ± 15.67)°,P <0.01],the group with intrathoricic anomalies or abdominal wall defect [(51.74 ± 15.97)°].ConclusionsThe reference ranges of fetal cardiac axis for local population in mid-second trimester may helpful for detecting congenital defects.Presence of an abnormal cardiac axis in the fetuses is associated with a substantial risk of congenital heart disease and/or other extra cardiac defects.
