OBJECTIVE: To investigate whether β-globin gene 3'UTR+101G>C (HBB:c.*233G>C) variant has genetic effect and provide basis for gene diagnosis and genetic counseling. METHOD: Whole blood cell analysis and capillary zone electrophoresis (CZE) were used to analyze the hematological indexes. The most frequent 23 mutations in southern Chinese individuals were routinely measured by PCR-flow fluorenscence immunmicrobeads assay. Sanger sequencing was used to detect the other variants of β-globin gene (HBB). RESULTS: In 463 cases, a total of 7 cases with HBB:c.*233G>C variant were detected, among them 4 cases carried other pathogenic variants of HBB gene (2 cases were in trans, 2 cases were in cis), who had typical hematological characteristics of mild β-thalassemia, and 3 cases also carried abnormal hemoglobin variation, but did not have hematological characteristics of β-thalassemia. CONCLUSION The study shows that HBB:c.*233G > C variant has no obvious genetic effect and should be a benign polymorphism.

Objective:To analyze the source of infection， clinical symptoms and epidemiological characteristics of pertussis surveillance cases in Minhang District of Shanghai from 2017 to 2019，so as to provide the basis for pertussis surveillance and immunization strategy. Methods:Descriptive epidemiological method was used to analyze the pertussis surveillance cases. Results:A total of 334 cases were included in the pertussis active surveillance system， 237 cases were confirmed cases. There were 13 towns or streets in Minhang District， except for Pujin Street， all the other 12 towns or streets had cases. The high risk group （131/237， 55.27% of the cases） were the infants under five months old who did not reach the age of immunization or did not complete the basic immunization of diphtheria， tetanus， and acellular pertussis combined vaccine （DTaP）. The cases mainly occurred in March to July， accounting for 71.31% （169/237）. The highest culture-positive rate of Bordetella pertussis was in August （82.76%， 24/29）； the highest positive rate of polymerase chain reaction （PCR） detection was in March （58.82%， 20/34）. All the monitored cases had cough symptoms with an average cough days of 22.05±9.81 in confirmed cases. A total of 64 clustered outbreaks were detected， with an attack rate of 37.45% （94/251）. 32.91% （78/237） of the cases had contact history with coughing patients 21 days before the onset， and 94.87% （74/78） of them were family members. The aggregation of pertussis was mainly transmitted from adults to infants and infants to adults. Conclusion:Children under five months old are the high incidence population of pertussis， and family members are the main source of infection. It is suggested that pertussis monitoring and prevention should be carried out in adolescents and adults.

Oral anticoagulants play an important role in the prevention and treatment of thromboembolic diseases.Warfarin,a traditional oral anticoagulant,is limited in clinical use due to its limitations such as narrow therapeutic window and requirements on frequent monitoring and dose adjustment.Direct oral anticoagulants(DOACs)such as dabigatran,rivaroxaban,apixaban,and edoxaban are increasingly used to prevent and treat venous thrombosis or thrombus formation.However,recent studies have documented inter-individual variability in plasma drug levels of DOACs.This article summarizes the recent advances in the pharmacogenomics of DOACs.

In the research community, resistance to apoptosis is often considered a hallmark of cancer. However, pathologists who diagnose cancer via microscope often see the opposite. Indeed, increased apoptosis and mitosis are usually observed simultaneously in cancerous lesions. Studies have shown that increased apoptosis is associated with cancer aggressiveness and poor clinical outcome. Furthermore, overexpression of Bcl-2, an antiapoptotic protein, is linked with better survival of cancer patients. Conversely, Bax, CD95, Caspase-3, and other apoptosis-inducing proteins have been found to promote carcinogenesis. This notion of the role of apoptosis in cancer is not new; cancer cells were found to be short-lived 88 years ago. Given these observations, resistance to apoptosis should not be considered a hallmark of cancer.

OBJECTIVETo further study the characteristics of drugs with neutral property in two-way application and conditioned dominance by observing the action characteristic of 10 traditional Chinese medicines with neutral property in hemorheological indicators of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats.

METHODThe model of heat stagnation and blood stasis syndrome rats was established by injecting carrageenan and dry yeast, while the model of cold stagnation and blood stasis syndrome rats was established by body freezing. Subsequently, 10 traditional Chinese medicines with neutral property, 5 traditional Chinese medicines with heat property and 5 traditional Chinese medicines with cold property were selected for intervention to observe the changes in such indicators as whole blood viscosity, plasma viscosity and hematocrit and analyze the action characteristics of drugs with neutral property.

RESULTANOVA showed that among six of the 10 traditional Chinese medicines with neutral property, including Typhae Pollen, Sarcandrae Herba and Sappan lignum, could obviously increase the hemorheological indicators of both heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats; five traditional Chinese medicines with cold property, such as Salviae Miltiorrhizae Radix et Rhizoma, Leonuri Herba, Rhei Radix et Rhizoma, could significantly ameliorate the hemorheological indicators of heat stagnation and blood stasis syndrome rats (P < 0.01 or P < 0.05), and Salvia Miltiorrhiza Radix et Rhizoma alone could ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.05); all of the five traditional Chinese medicines with heat property could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.01), among which Carthami Flos and Notoginseng Radix et Rhizoma could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats. According to the average high-shear blood viscosity analysis, drugs with neutral property showed similar action characteristics to those with cold property in ameliorating hemorheology indicators of heat stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity; and traditional Chinese medicines with neutral property have the similar action characteristics to those with heat property in improving the hemorheology indicators of cold stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity.

CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with cold property; but under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with heat property. This indicates that traditional Chinese medicines with neutral property show both heat and cold properties under he conditions of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome.
