OBJECTIVETo observe the effects of navel-warming therapy on clinical efficacy in patients with yang-deficiency tympanites based on regular treatment of western medication.

METHODSOne hundred and twenty cases of yang-deficiency tympanites were randomly divided into a navel-warming therapy group and a western medication group, sixty cases in each one. The regular treatment of western medicine was applied in the western medication group, including oral administration of antiviral drug and diuretics as well as intravenous drip of hepatic protector. Based on western medicine treatment, the navel-warming therapy was applied in the navel-warming group. A medical cake was laid on Shenque (CV 8), and then a medical cylinder was placed above the medical cake and ignited. The treatment was given once daily. One month was considered as a treatment session in both groups and totally one session was required. The TCM symptom score, B-ultrasound ascites and temporary use of diuretics before and after treatment were observed in both groups; also the efficacy was evaluated.

RESULTSThe total effective rate was 81.7% (49/60) in the navel-warming therapy group, which was superior to 56.7% (34/60) in the western medication group (P < 0.05). After the treatment, the TCM symptom score and ascites were improved in both groups (all P < 0.05), which was more significant in the navel-warming therapy group (all P < 0.05). The temporary use of diuretics was statistically different between the two groups (P < 0.05), indicating the navel-warming therapy group could obviously reduce or stop the use of diuretics.

CONCLUSIONBased on regular treatment of western medication, the navel-warming therapy could significantly improve therapeutic efficacy, effectively relieve clinical symptoms and ease ascites.

ObjectiveTo investigate the epidemic situation of brucellosis in Datong city, and to provide scientific evidence for making appropriate prevention and control measures. MethodsSurveillance data of human brucellosis in 7 countris and 4 districts in Datong city between 2006 and 2009 were collected, throng the national network straight quote system in an infectious diseases. Excel database was established and all data were statistically analyzed. Incidence of brucellosis in local population was analyzed. The regional distribution, time distribution,occupation, age and sex distribution were analyzed. Epidemic characteristics and trend of brucellosis in Datong city were summarized. Results A total of 5195 cases of brucellosis patients in Datong were found between 2006 and 2009, the average incidence rate was 57.51/10 million. All counties had the disease, and the onset of the disease mainly in the spring and summer. Most cases were young males. Farmer case was 81.67％(4243/5195) of the total patients. ConclusionsFrom 2006 to 2009, epidemic characteristic of Datong human brucellosis ishigh-low-high(incidence). We suggests the Department concerned to strengthen the prevention and control of the disease in some counties, focusing on spreading of disease prevention and control knowledge among farmers and increase their self-protection awareness.

Objective To provide reference for anti-infection drugs in Zunyi area by analyzing the etiological characteristics of children with severe pneumonia.Methods The sputum, throat swabs and serum of children with severe pneumonia in pediatric intensive care unit of our hospital from January 2014 to December 2015 were collected in this study.The pathogen species which caused severe pneumonia were detected and identified by the method of pathogen culture,and typical pathogens were detected by RT-PCR and indirect immunofluorescence.Results A total of 337 children with severe pneumonia were included,the pathogen positive rate was 86.65%(292/337).The rate of viral infection(37.32%)was the highest,followed by bacterial infection accounting for 28.42%,then the mixed infection accounting for 27.74%,and the mycoplasma pneumoniae infection accounting for 6.50%.The respiratory syncytial virus type B accounting for 28.44% was the most common in viral infection,and there were significant differences in age distribution(P<0.05),the children under 3-years-old,especially the infants under 1-year-old had the highest susceptibility.Viral infection had certain seasonality,compared with spring and winter,autumn and winter(November to April) had higher viral detection rate and the difference was statistically significant(x2=29.28,P=0.001).The escherichia coli was the most common in bacterial infection,accounting for 21.69%.Klebsiella pneumoniae,Escherichia coli were more common in neonates and infants under 1-year-old,Haemophilus influenzae occured in 1~3 years old children,Streptococcus pneumoniae infection could occur in any age.Conclusion Viral infection is the most common pathogen in children with severe pneumonia in Zunyi area followed by bacterial infection,which is more common in children under 1-year-old,and with the high incidence in autumn and winter.Bacterial infection is more common in children over 3 years of age.Bacterial and viral mixed infection is common in children under 3 years of age,especially in children under 1-year-old.

In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC₅₀ values of 3.77 μmol·L^-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.

OBJECTIVE: To work out a qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer. METHODS: Based on the collection and analysis of related medical literature, clinical investigation, and experts' discussion, a preliminary qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer was formulated. Then it was used in clinic to be verified and revised repeatedly till it was improved to be a satisfied formal criterion. RESULTS: The basic syndromes listed in the qualitative diagnostic criterion for basic syndromes in patients with primary liver cancer consisted of two parts: excessive syndromes, including the syndromes of stagnation of qi, blood stasis, excess-heat and dampness, and deficient syndromes, including the syndromes of deficiency of qi, deficiency of blood, deficiency of yin and deficiency of yang. Each of the above syndromes could be diagnosed according to specific combination of its corresponding symptoms or signs. The clinical verification results showed that the total matching ratio was 73.92% between the diagnoses made according to the criterion and the diagnoses acquired from the experts' experience. CONCLUSIONS: The qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer is coincident with the experts' clinical practice. However, it needs to be further studied.
