Characteristics of Traditional Chinese Medicine Syndromes and Treatments of COVID-19 Patients from Two Hospitals Based on “Treatment of Disease in Accordance with Three Conditions” / 中国实验方剂学杂志

ObjectiveTo explore the guidance value of “treatment of disease in accordance with three conditions” theory in the prevention and treatment of corona virus disease 2019（COVID-19） based on the differences of syndromes and traditional Chinese medicine（TCM） treatments in COVID-19 patients from Xingtai Hospital of Chinese Medicine of Hebei province and Ruili Hospital of Chinese Medicine and Dai Medicine of Yunnan province and discuss its significance in the prevention and treatment of the unexpected acute infectious diseases. MethodDemographics data and clinical characteristics of COVID-19 patients from the two hospitals were collected retrospectively and analyzed by SPSS 18.0. The information on formulas was obtained from the hospital information system （HIS） of the two hospitals and analyzed by the big data intelligent processing and knowledge service system of Guangdong Hospital of Chinese Medicine for frequency statistics and association rules analysis. Heat map-hierarchical clustering analysis was used to explore the correlation between clinical characteristics and formulas. ResultA total of 175 patients with COVID-19 were included in this study. The 70 patients in Xingtai，dominated by young and middle-aged males，had clinical symptoms of fever， abnormal sweating，and fatigue. The main pathogenesis is stagnant cold-dampness in the exterior and impaired yin by depressed heat， with manifest cold， dampness， and deficiency syndromes. The therapeutic methods highlight relieving exterior syndrome and resolving dampness， accompanied by draining depressed heat. The core Chinese medicines used are Poria，Armeniacae Semen Amarum，Gypsum Fibrosum，Citri Reticulatae Pericarpium，and Pogostemonis Herba. By contrast，the 105 patients in Ruili， dominated by young females， had atypical clinical symptoms， and most of them were asymptomatic patients or mild cases. The main pathogenesis is dampness obstructing the lung and the stomach， with obvious dampness and heat syndromes. The therapeutic methods are mainly invigorating the spleen， resolving dampness， and dispersing Qi with light drugs. The core Chinese medicines used are Poria，Atractylodis Macrocephalae Rhizoma，Glycyrrhizae Radix et Rhizoma，Coicis Semen，Platycodonis Radix，Lonicerae Japonicae Flos， and Pogostemonis Herba. ConclusionThe differences in clinical characteristics， TCM syndromes， and medication of COVID-19 patients from the two places may result from different regions，population characteristics， and the time point of the COVID-19 outbreak. The “treatment of disease in accordance with three conditions” theory can help to understand the internal correlation and guide the treatments.

Mechanical analysis of the single microparticle motion in blood vessel / 医用生物力学

Objective To analyze the force condition of a single microparticle in blood vessel and the factors that influencing its motion. Method The microparticles in blood vessel during targeted drug delivery were studied, and the fluid flow in blood vessel was simplified as the Poiseuille flow in parallel plate flow chamber. Specific methods for calculating each force subjected on the single microparticle in the flow field were analyzed. The motion equations of the single microparticle were determined through calculation of its force balance and torque balance. The relationship between the force subjected on the single microparticle and the particle diameter/flow rate as well as the critical motion conditions of the particle diameter and flow rate were obtained by numerical calculation. Results The single microparticle was more subjected to the motion of rolling, sliding and ascending with the increase of flow rate and particle diameter. In flow rate and particle diameter diagrams, the critical curve of ascending motion located above that of sliding motion, while the rolling curve was located at the bottom.Conclusions The microparticle will not do the ascending motion under the condition of blood flow rate in human. As the blood flow rate reduces, the motion of microparticle with given diameter will be transfered from sliding to rolling, and will be entirely still under the condition of elastic deformation. Therefore, the proper selection of mircoparticle diameter and its surface adhesivity is critical for the drug particle to transport to the target location.

Inhibitory effect of 4-chlorobenzoyl berbamine on imatinib-resistant K562 cells in vitro and in vivo / 南方医科大学学报

<p><b>OBJECTIVE</b>To observe the inhibitory effect of 4-chlorobenzoyl berbamine (BBD9) on imatinib-resistant cell line K562 (K562/IR) in vitro and in vivo and explore the mechanisms.</p><p><b>METHODS</b>The IC50 of BBD9 and berbamine (BBM) was determined by MTT assay. The expressions of p210(Bcr-Abl), IKKa, cytoplasmic and nuclear NF-κBp65 were determined using Western blotting in K562/IR cells following a 48-h exposure to 0.5 µg/ml BBD9 or 8 µg/ml BBM. Flow cytometry was used to analyze the cell viability, apoptosis and necrosis; Western blotting was employed to determine the expressions of PARP, caspase-3, caspase-9 and LC3II in K562/IR cells exposed to different concentrations of BBD9 for 48 h. In nude mouse models bearing K562/IR cell xenograft, the tumor weight, tumor regression, and body weight changes of the mice were measured after treatments with 15 mg/kg and 30 mg/kg BBD9 and 100 mg/kg imatinib.</p><p><b>RESULTS</b>The IC50 of BBD9 and BBM was 0.73 µg/ml and 5.43 µg/ml, respectively. In K562/IR cell cultures, the expressions of p210(Bcr-Abl), IKKa and nuclear NF-κB p65 were all decreased following BBD9 and BBM treatments, but BBD9 produced more potent effect; cytoplasmic NF-κB p65 showed no obvious changes after the treatments. The cell apoptosis and necrosis increased with the concentrations of BBD9, which also dose-dependently increased the levels of cleaved caspase-3, csapase-9, PARP, and LC3II expression. In the tumor-bearing mouse model, BBD9 showed stronger effects than imatinib in reducing the tumor weight, promoting tumor regression, and increasing the body weight.</p><p><b>CONCLUSION</b>BBD9 can effectively inhibit the growth of K562/IR cells in vitro and in vivo by activating cell apoptosis, necrosis and autophage pathways, down-regulating expressions of p210(Bcr-Abl) and IKKa and suppressing the cytoplasm-to- nucleus translocation of NF-κBp65.</p>

Epidemiological surveillance of norovirus and rotavirus diarrhea among outpatient children in five metropolitan cities / 中华儿科杂志

<p><b>OBJECTIVE</b>To survey the clinical epidemiological features of norovirus and rotavirus diarrhea among children living in 5 cities.</p><p><b>METHOD</b>A prospective epidemiological investigation was conducted among outpatient children with acute diarrhea between August 2008 and July 2009 in Shanghai, Hangzhou, Guangzhou, Chongqing and Tianjin. The stool samples were randomly collected from children with non-dysentery diarrhea. Group A rotavirus antigen was tested by the kit that applies colloidal gold method in all specimens. GI and GII genogroups of norovirus were detected by one-step real-time reverse-transcription polymerase chain reaction (RT-PCR). The detection rates, seasonality and susceptible age of both viruses-associated diarrhea were analyzed.</p><p><b>RESULT</b>During the one-year period, 5091 fecal samples were obtained, of which 1563 (30.7%) were rotavirus-positive. The detection rates of rotavirus were 29.5% (268/916) in Shanghai, 36.1% (334/926) in Hangzhou, 26.3% (254/968) in Guangzhou, 34.1% (359/1054) in Chongqing and 28.2% (348/1233) in Tianjin, respectively. Among the remaining 3528 rotavirus-negative samples, 1049 (29.7%) were identified to be norovirus-positive. The detection rates of norovirus were 21.2%(136/642) in Shanghai, 31.3% (185/592) in Hangzhou, 24.2% (173/714) in Guangzhou, 31.8% (221/695) in Chongqing and 37.7% (334/885) in Tianjin, respectively. It is estimated that the infection rate of norovirus among outpatients with acute diarrhea is at least more than 20.6% (1049/5092). Of 1049 norovirus strains, 1036 (98.7%) were GII genogroup and 16 (1.5%) were GI genogroup, 3 were mixed with GI and GII genogroups. The 1049 children with norovirus diarrhea aged between 1 month and 14 years with the median age of 10 months (mean: 13.9 ± 16.9 months) and 91.8% were 2 years old or younger. The 1563 children with rotavirus diarrhea aged between 1 month and 11.3 years with the median age of 10 months (mean: 12.9 ± 13.7 months) and 92.5% were 2 years old or younger. The median ages between norovirus-infected children and rotavirus-infected children were significantly different (P < 0.05). The peak seasons of rotavirus diarrhea spanned autumn and winter (from October to February). The peak seasons of norovirus diarrhea presented in the winter and spring (from November to April) in Tianjin. Norovirus became active in April and usually predominantly prevalent in the summer and autumn (from July to October) in Shanghai, Hangzhou and Chongqing. However, norovirus was sporadically prevalent in the spring and detected more commonly in the other seasons in Guangzhou.</p><p><b>CONCLUSION</b>Both rotavirus and norovirus are the major causative agents for childhood diarrhea. The seasonality of rotavirus diarrhea was similar among the 5 cities. Nevertheless, the seasonality of norovirus diarrhea was diverse in the different areas. In Tianjin located in the north of China, norovirus was quite prevalent in the cold season. In the east (Shanghai and Hangzhou) and south-west (Chongqing), norovirus prevailed dominantly in the summer and autumn. In the south (Guangzhou), the activity of norovirus was more obvious in the summer, autumn and winter.</p>

Correlation of cyclooxygenase 2 expression with microlymphatic density and its clinical significance / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To study the expression of cyclooxygenase-2 (COX-2) in esophageal carcinoma and its correlation with microlymphatic density (MLD), and to investigate the clinicopathological and prognostic significance of COX-2 and MLD in patients with esophageal cancer.</p><p><b>METHODS</b>COX-2 expression and MLD were detected by immunohistochemistry in 100 cases of esophageal squamous cell carcinoma. Follow up was available in 76 patients. Multivariable Cox regression was used to analyze the association between the laboratory indices and overall survival of patients with esophageal carcinoma.</p><p><b>RESULTS</b>COX-2 expression was present in 73% of patients. MLD in patients with high COX-2 expression (99.71±39.62) was significantly higher than that in those with low or no COX-2 expression (80.22±30.36) (P<0.05). No correlations were observed between the over expression of COX-2 and clinicopathologic parameters including tumor size and lymphatic metastasis (P<0.05). However, MLD was associated with lymphatic metastasis and the depth of invasion (P<0.05, P<0.01). In the 76 patients with followed up, the median survival was 25.5 months. Cox regression showed that the COX-2 expression, histological grade of the tumor and MLD were risk factors of overall survival of esophageal carcinoma.</p><p><b>CONCLUSIONS</b>COX-2 may contribute to the lymphangiogenesis in the tumor. COX-2 may be a new target point for the treatment of esophageal carcinoma. COX-2 expression and microlymphatic vessel density are of significant prognostic value for esophageal carcinoma.</p>

<p><b>OBJECTIVE</b>To investigate whether green tea consumption can reduce the risk of adult leukemia.</p><p><b>METHODS</b>A hospital-based matched case-control study was conducted in 2005 - 2006. We recruited 107 confirmed leukemia cases and 110 inpatient controls with orthopedic disease without leukemia or other malignancy matched on gender, age and hospitals that patients stayed. Related information were gathered on quantity, duration and frequency of tea consumption, demographic characteristics, exposure to radiation and occupational hazards, medications, using a validated questionnaire by face-to-face interview. Univariate and multivariate unconditional logistic regression analysis were used to estimate odds ratios (ORs) and associated 95% confidence intervals (CIs) with SPSS 11.5 software.</p><p><b>RESULTS</b>Compared with non-tea-drinkers, the OR of those who consumed green tea was 0.58 (95% CI:0.34-1.00, P< 0.05) under univariate statistical analysis. The OR was 0.52 ( 95% CI: 0.28- 0.98, P = 0.04), using logistic regression to count for age, gender, residential area, smoking, level of education, exposure to radiation, benzene and organo-phosphorus. Compared with non-drinkers, the risk of adult leukemia declined with increasing quantity, duration, and frequency of green tea consumption. Tests for trend on dose-response was statistically significant (P < 0.01).</p><p><b>CONCLUSION</b>A higher consumption of green tea seemed to be associated with a declined risk of adult leukemia. Tea consumption might be of help to human health planning projects.</p>

Novel distribution pattern of fibrinolytic components in rabbit tissues extract: a preliminary study / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVE</b>The purpose of this work was to investigate the distribution pattern of fibrinolytic factors and their inhibitors in rabbit tissues.</p><p><b>METHODS</b>The components of the fibrinolytic system in extracts from a variety of rabbit tissues, including tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), plasminogen (Plg), plasmin (Pl) and alpha(2) plasmin inhibitor (alpha(2)PI), were determined by colorimetric assay.</p><p><b>RESULTS</b>The tissue extracts in renal, small intestine, lung, brain and spleen demonstrated strong fibrinolytic function, in which high activity of tPA, Plg and Pl was manifested; whereas in skeletal muscle, tongue and stomach, higher activity of PAI-1 and alpha(2)PI showed obviously. Also excellent linear correlations were found between levels of tPA and PAI-1, Pl and alpha(2)PI, Plg and Pl. In related tissues, renal cortex and renal marrow showed distinctly higher activity of tPA and lower activity of PAI-1, with the levels of Plg and Pl in renal cortex being higher than those in renal marrow, where the alpha(2)PI level was higher than that in renal cortex. Similarly, the levels of tPA, Plg and Pl in small intestine were higher than those in large intestine, but with respect to PAI-1 and alpha(2)PI, the matter was reverse. In addition, the fibrinolytic activity in muscle tissue was lower, however, the levels of tPA, Plg, and Pl in cardiac muscle were obviously higher than those in skeletal muscles, and the levels of PAI-1 and alpha(2)PI were significantly lower than those in skeletal muscle.</p><p><b>CONCLUSION</b>Our data demonstrate that a remarkable difference of the fibrinolytic patterns exists in rabbit tissues, which has probable profound significance in understanding the relationship between the function of haemostasis or thrombosis and the physiologic function in tissues.</p>

<p><b>OBJECTIVE</b>To determine the therapeutic effectiveness and safety of polyethylene glycol 4000 (forlax) in the treatment of constipation in children over 8 years old.</p><p><b>METHODS</b>This study was designed as a randomized, positive medicine (lactulose) controlled multicenter trial. A total of 216 children with constipation from 8-18 years old from 7 hospitals across China who were matched with a uniform entry criteria were enrolled in this study. The 216 patients were randomized to receive either oral forlax (20 g/d, n=105) or lactulose (15 mL/d, n=111) for 2 weeks. The therapeutic effects, including bowel movement frequency, stool consistency, clinical complete remission rate of constipation and abdominal symptoms, and the safety of forlax and lactulose were evaluated at 1 and 2 weeks of treatment.</p><p><b>RESULTS</b>The median weekly frequency of bowel movement in the forlax group increased by 4 and 5 times respectively after 1 and 2 weeks of treatment, and increased by 3 and 4 times in the lactulose group (P < 0.05). The stool consistency of the two groups was both improved significantly after treatment. The Bristol score of stool consistency of the forlax and lactulose groups were 3.41+/-1.11 and 3.64+/-1.33 respectively (P < 0.05) after 1 week of treatment, and were 4.26+/-0.89 and 3.63+/-1.33 respectively (P < 0.05) after 2 weeks of treatment. The clinical complete remission rate of constipation in the forlax and lactulose groups was 70% and 40% respectively (P < 0.05) by week 1 of treatment, and that was 72% and 41% respectively (P < 0.05) by week 2 of treatment. Abdominal pain disappeared in 75% of patients in the forlax group but in only 57% in the lactulose group by week 2 of treatment (P < 0.05). No serious adverse events happened and no abnormalities were found in laboratory tests and physical examinations in the two groups after medication.</p><p><b>CONCLUSIONS</b>Forlax is safe and effective in the treatment of constipation in children over 8 years old.</p>

<p><b>OBJECTIVE</b>To evaluate the safety of domestically produced idarubicin in the treatment of acute leukemia by a multicenter randomized control trial.</p><p><b>METHODS</b>This trial was carried out in the hemotologica department of five hospitals throughout China, with hospitalized patients who suffered from acute myelogenous leukemia ( AML except M3 type) , acute lymphocytic leukemia ( ALL) , chronic myelogenous leukemia-blast (CML-blast) , totally 155 patients. Those with severely cardial, hepatic or renal disfunction or those who had ever treated with > or = 200 mg/m(2) idarubicin were excluded from the trial. All patients signed the letter of consent as required by the Ethics Committee of our government. In this study, 155 leukemia patients were randomly grouped into: 1. test group treated using domestic idarubicin, 2. control group using imported idarubicin. The acute myelogenous leukemia regimen included idarubicin 8 mg/m(2), dl -3 plus cytosine arabinoside 100 mg/m(2), dl - 7 for 1-2 cycles. The regimen for acute lymphocytic leukemia was idarubicin 8 mg/m2, dl - 3; vincristine 2 mg/mr, dl; cyclophosphamide 750 mg/m2, dl ; plus prednisone 60 mg/m(2),dl - 14 for 1-2 cycles.</p><p><b>RESULTS</b>Clinical response rate of the tested group treated with domestic idarubicin and control group treated with imported idarubicin was 78. 1% (50/64) vs. 76.9% (50/65) without any statistically significant difference between the two groups(P >0. 05). Grade Ill - IV hematological toxicity rate of the domestic idarubicin group and imported idarubicin group was 74. 0% vs. 73. 1% , respectively (P = 0. 73). Drug-related death was observed in 3 of 77 patients in the domestic idarubicin group (3.9%) due to cerebral hemorrage or septic infection. The incidence of non-hematological toxicities in domestic idarubicin group and imported idarubicin group was 84. 4% vs. 79. 5% for nausea or vomiting, 70. 1% vs. 71. 8% for infection, 42. 9% vs. 41. 0% for mucositis, 33. 8% vs. 33. 3% for alopecia, 28.6% vs. 28. 2% for serum glutamicoxalacetic transaminase abnormalitis, 16. 9% vs. 10. 3% for cardiac toxicity, all without statistically significant differences between these two groups (P > 0. 05). Discontinuation of treatment due to non-hematological toxicity was not neccessary.</p><p><b>CONCLUSION</b>Domestic idarubicin is comparable to imported counterpart in efficiency and safety for the treatment of acute leukemia. The most severe side effects of domestic idarubicin is hematological toxicity, which should be closely observed and treated in time, while its non-hematological toxicity is tolerable.</p>

Application of bone marrow biopsy imprint in evaluating cellularity / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To study the value of bone marrow biopsy imprint in evaluating cellularity.</p><p><b>METHODS</b>The bone marrow tissues were obtained by trephine biopsy from 272 patients, and then put on the slides to make the imprints. The imprints was stained by Wright-Giemsa method, and the bone marrow smears and imprints were examined simultaneously according to the bone marrow cellularity criteria.</p><p><b>RESULT</b>In bone marrow cellularity, four grades (distinct decrease, extreme decrease, distinct increase, and extreme increase) were significantly higher in bone marrow imprints than those in bone marrow smears (P <0.05), but there was no significantly differences between bone marrow imprints and sections (P >0.05). Using bone marrow sections as standard, in cellularily decreasing samples, the consistent rate of bone marrow imprints and smears were both high (84.4% and 97.9%), in the group of the normal and increased cellularity, the consistent rate of the bone marrow imprints (84.4% and 97.7%) was significantly higher than that in smears (60% and 64%, P<0.01). The sensitivity, specificity, Youden index, positive predictive value and positive likelihood rate of bone marrow imprints were all higher than those of the smears. Using the bone marrow sections as gold standard, in 124 cases with decreased cellularity in smears, the positive diagnosis rate for aplastic anemia and dyshaematopoiesis based on bone marrow imprints was 37.1% with a false positive rate of 7.3% which was lower than that of the bone marrow smears (false positive rate of 29.8%, P<0.01).</p><p><b>CONCLUSION</b>To evaluate bone marrow cellularity, bone marrow imprint is better than bone marrow smear. The combination of the two examinations can make the diagnosis more convenient and quicker.</p>
