Abstract: Objective To evaluate the influence of coronavirus disease 2019 (COVID-19) prevention and control measures on the transmission and epidemic of influenza in Chongqing, so as to provide references for formulating targeted influenza prevention and control strategies. Methods The influenza surveillance data, during the year 2018 to 2020, were collected through the "China Influenza Surveillance Information System", and the seasonal characteristics of influenza epidemic were analyzed. The percentage of influenza like cases (ILI%) and influenza virus positive rate between 2020 and 2018-2019 were compared, so as to evaluate the impact of COVID-19 prevention and control measures on influenza epidemic characteristics. Results The annual proportions of ILI cases in Chongqing were respectively 3.53%, 2.23% and 1.2% from 2018 to 2020, while the positive rates of influenza virus were respectively 13.97%, 23.81% and 2.65%. The distribution trend of ILI% from 2018 to 2019 fluctuated were similar, but it continued to drop and remain at a low level since February 2020. The positive rate of influenza virus showed an epidemic peak from December to March in 2018-2019, also peaked from November 2019 to January 2020, but decreased to 0 in March. ILI% was positively correlated with the positive rate of influenza virus (r=0.404 8, P<0.05). In 2020, compared with the same period of 2018-2019, the growth rate of ILI% was -66.09% and -46.32%, respectively. The positive rate of influenza virus in 2020 decreased by 81.03% and 88.87% compared with the same period of 2018-2019, respectively. The growth rates of influenza virus positive rate in January 2020 were decreased with a small rate of about 39.87%, and with a significantly decline of more than 93.65% from February. No influenza epidemic was found after March. Conclusions Since COVID-19 prevention and control measures were implemented in January 2020 in Chongqing, the ILI% and the positive rate of influenza virus in sentinel hospitals decreased significantly. In the season of high incidence of respiratory infectious diseases, personal protection and other measures can effectively reduce influenza virus infection.

OBJECTIVETo analysis the early complications of tibial fracture and its related factors, and propose a solution.
METHODSFrom December 2003 to December 2013,38 patients with early complications of tibial plateau fracture after operation were retrospectively analyzed. There were 35 males and 3 females, aged from 37 to 69 years old (averaged 42.3 years). According to Schatzker classification, 3 cases were classified as type II, 2 cases as type III, 2 cases as type IV, 19 cases as type V, 12 cases as type VI. The intervals between injury and operation ranged from 9 hours to 9 days, 26 cases within 3 days. Fifteen cases were treated with internal fixation of plates and 23 were treated by plate fixation and bone transplantation. Early complications included skin necrosis in 15 cases, infection in 6 cases, osteofascial compartment syndrome in 3 cases, common peroneal nerve injury in 2 cases, the superficial peroneal nerve injury in 3 cases, popliteal artery injury in 2 cases, loss of reduction in 7 cases.
RESULTSThe wound of 14 cases healed at the first stage and 24 cases healed delay. Hospitalization days ranged from 7 to 67 days (averaged 25.6 days). All patients were followed up for 12 to 36 months with an average of 16.4 months. The fracture healing time ranged from 3 to 9 months (averaged 6.9 months). According to Merchant knee function evaluation criteria, the results were excellent in 19 cases, good in 12, fair in 5 and poor in 2.
CONCLUSIONEarly complications of tibial fracture after operation is closely associated with the severe fracture complexity and related with preoperative preparation, surgical timing, operation incision selection and surgical technique. Early detection and timely processing reduce damage.

OBJECTIVETo investigate the distribution features of Chinese medical constitutions in hypertension complicated diabetes patients.
METHODSRecruited were 251 primary hypertension inpatients at the Department of Neurology and the Department of Cardiology, Mindong Hospital of Ningde City from October 2010 to March 2011. They were assigned to two groups according to whether they were complicated with diabetes, i.e., the primary hypertension complicated diabetes (as the case group, 78 cases) and the primary hypertension without complicated diabetes (as the control group, 173 cases). The constitution types were investigated by questionnaire. The constitution type distribution was compared between the two groups. The data including gender, age, and the distribution of the constitution type were compared between the two groups. The levels of TG, TC, LDL-C, Hb, FPG, and ALB were detected on the 2nd day after admission. The levels of TG, TC, LDL-C, Hb, and ALB were compared be- tween the two groups in patients of yin deficiency constitution, phlegm dampness constitution, and qi deficiency constitution.
RESULTSThere was no statistical difference in the hypertension grading, the disease course, and chronic disease complications between the two groups (P > 0.05). The main constitution types were yin deficiency (accounting for 26.0%), phlegm dampness (accounting for 19.1%), and qi deficiency (accounting for 19.1%) in the control group. The main constitution types were yin deficiency (accounting for 32.1%), phlegm dampness (accounting for 30.8%), and qi deficiency (accounting for 17.9%) in the case group. The ratio of phlegm dampness type in the case group was higher than that in the control group with statistical difference (P = 0.041). There was no statistical difference in the constitution distribution in the same gender between the two groups (P > 0.05). There was no statistical difference in the constitution distribution in those younger than 80 years between the two groups (P > 0.05). Compared with those older than 80 years in the control group, the ratio of phlegm dampness was higher, and the ratios of yang deficiency, yin deficiency, qi deficiency, and dampness heat were lower in the case group with statistical difference (P = 0.020). There was no statistical difference in the constitution distribution among different age stages in the case group (P > 0. 05). But there was statistical difference in the constitution distribution among different age stages in the control group (P < 0.05). The yin deficiency and qi deficiency constitutions were dominated in thinner patients of the control group, while yin deficiency constitution was dominated in thinner patients of the case group, showing no statistical difference between the two groups (P > 0.05). There was no statistical difference in the distribution of constitution type in overweight patients between the two groups (P = 0.458). Compared with those of gentle type constitution in the same group, the levels of TC and LDL-C increased in those of phlegm dampness constitution in the two groups (P < 0.05). The level of TC increased in those of qi deficiency constitution in the case group. The level of Hb decreased in those of qi deficiency constitution in the control group (P < 0.05). Compared with those of qi deficiency constitution in the same group, the levels of TC and Hb obviously increased in those of phlegm dampness constitution in the control group (P < 0.05). The level of ALB increased in those of yin deficiency constitution in the case group (P < 0. 05). Compared with the control group, the level of FPG of those of each constitution increased in the case group (P < 0.05) ,.and the level of TC increased in those of qi deficiency constitution (P = 0.007).
CONCLUSIONSThe main constitution types of hypertension complicated diabetes patients were yin deficiency, phlegm dampness, and qi deficiency. The ratio of phlegm dampness was higher in hypertension complicated diabetes patients than hypertension without complicated diabetes patients. The levels of TC and LDL-C were higher in those of phlegm dampness constitution type. The level of TC was higher in hypertension complicated diabetes patients of qi deficiency constitution.

OBJECTIVEto study the clinicopathological features, imaging characteristics, immunophenotypes and differential diagnosis of giant cell angioblastoma (GCAB).
METHODSa case of GCAB in the left middle-upper tibia and fibula was studied by light microscopy, X-ray and CT imaging, immunohistochemistry.
RESULTSX-ray and CT imaging showed a clearer lesion in the left middle-upper tibia than in the ipsilateral fibula with enlarged ostealleosis and increased inhomogeneously medullary cavity density, irregular thickening of cortical bone, local cortical default at the inner edge, soft tissue swelling around the abnormal bone. Histologically, tumor tissue was located between the bone trabeculae by nodular, linear and plexiform aggregates of oval-to-spindle cells, large mononucleate cells and multinucleate giant cells with prominent nucleoli and abundant granular eosinophilic cytoplasm. Some aggregates had uncentain amount of discernible lumens, either empty or containing few erythrocytes. A concentric arrangement of oval-to-spindle Cells around small-caliber vascular structures together with collagen fiber contributed to a so-called 'onion-skin' arrangement. The background showed a loose mesenchymal stroma formed of some inconspicuous spindle-fibroblast-like cells, stellate-shape mesenchymal cells, a moderate mononuclear inflammatory cell infiltrate and scattered mast cells. Immunophenotype showed the tumor cells and giant cells strongly positive for vimentin. A good many oval-to-spindle cells stained markedly for CD31 and CD34, but weakly for FVIII, while the giant cells are highlighted instead by CD68, occasionally, very few giant cells showed positive focally for FVIII, a-SMA decorated notedly the cells surrounding the endothelium-like cells but weakly positive in some other tumor cells.
CONCLUSIONGCAB is a rare, locally infiltrative but slow growing neoplastic angiogenesis with unique morphological characteristics during infancy, which may occur not only in the skin, mucosa, subcutis and deep soft tissue but also in the bone.

OBJECTIVETo study the clinical features and ABCG5/ABCG8 gene mutations of three pedigrees of phytosterolemia presented with macrothrombocytopenia and hemolysis.
METHODSErythrocyte and platelet morphology were examined under light microscope. Plasma sterol levels were measured by high pressure/performance liquid chromatography method. All of ABCG5 and ABCG8 exons and intron-exon boundaries were directly sequenced to identify mutations, the corresponding gene mutation sites of three families members and healthy individuals were detected.
RESULTSAll the patients presented macrothrombocytopenia, hemolysis, splenomegaly and xanthomas. The blood smears showed large platelets, some as large as erythrocytes, and abnormal erythrocyte shapes, such as stomatocytes. Plasma concentrations of phytosterols, especially sitosterol were markedly elevated (30 fold) in the affected patients. Four mutations were identified in these three pedigrees, ABCG5 C20896T (R446X) and A20883G, ABCG8 del43683-43724 and del1938C-1939G/ins1938T. The latter three were novel mutations reported for the first time.
CONCLUSIONSPhytosterolemia associated with macrothrombocytopenia and hemolysis is a new subtype of this disease. Plasma phytosterols and related gene analysis should be performed when ever an unexplained macrothrombocytopenia, especially combined with haemolysis or/and stomatocytosis.

This study was aimed to investigate the pro coagulation effects of hemocoagulase atrix and its effective components (batroxobin and factor X activator) on plasma of normal subjects and patients with bleeding disorders and their mechanisms. Activated partial thromboplastin time (APTT) and prothrombin time (PT) were measured. The factor (F)X activation and thrombin generation were analyzed by using chromogenic substrate method. The results showed that the plasma APTT of normal subjects was shortened by hemocoagulase atrix, batroxobin and FX activator, and the effect of FX activator was found to be concentration-dependent (r = 0.889, P < 0.05). The prolonged APTT of plasma from patients with bleeding disorders could be corrected by hemocoagulase atrix, batroxobin and FX activator, but PT showed no great changes resulted from the treatments. FX activator could promote FX activation and thrombin generation, while neither hemocoagulase atrix nor batroxobin showed such abilities. It is concluded that hemocoagulase atrix promotes coagulation process, and corrects coagulation abnormalities in patients with bleeding disorders, its main component batroxobin directly acts on fibrinogen, and FX activator promotes thrombin generation through activating FX.

OBJECTIVETo compare the protective activity of liver injury induced by D-galactosamine (GalN) between Huangqin-Tang and their metabolites by human intestinal bacteria(HIB).
METHODThe liver injuries in conventional and pseudo-germfree mice were induced by GalN. After oral administration of Huangqin-Tang and their metabolites mixtures by HIB, the serum transaminase (ALT and AST) activities were detected.
RESULTIn conventional mice, large and medium doses (20 and 10 g.kg-1) of Huangqin-Tang decoction significantly reduced the increase of serum ALT activity after 18 h GalN treatment. In pseudo-germfree mice, metabolites significantly reduced the ALT levels. However, Huangqing-Tang didn't affect the ALT levels in this kind of mice. To all of the animals, AST levels remained the same after oral Huangqin-tang or their metabolites.
CONCLUSIONThe metabolism by intestinal bacteria plays a role in pharmacological effects of constituents of Chinese herbal medicine. The metabolites of the constituents by intestinal bacteria were the real active components in vivo.
