Huaier (Trametes robiniophila) has been widely used as an adjuvant drug for cancer treatment in China. The anti-cancer effect of Huaier extract has been confirmed in liver cancer, lung cancer, breast cancer, ovarian cancer, gastric cancer, and so on. The main mechanisms by which Huaier exerts an anti-neoplastic effect include inhibition of the growth and proliferation of cancer cells, induction of apoptosis of cancer cells, suppression of angiogenesis, inhibition of the invasion and migration of cancer cells, regulation of oncogenes and tumor suppressor genes expression, improving immunity, and reversal of drug resistance in cancer cells. In order to provide references for further study and clinical application on anti-tumor effect of Huaier, the latest research progress on anti-tumor effect of Huaier in recent years is summarized in this paper.

In order to investigate the mechanism, the correlation between the odor change in Crataegi Fructus stir-fried process and 5-HMF were studied. Required samples were retrieved from Crataegi Fructus stir-fried process. Statistical quality control (SQC) was used to analyze the response values acquired by the electronic nose. At the same time, the content of 5-HMF was detected by high performance liquid chromatography (HPLC). Correlation analysis was used to analyze the relationship between the above two. Experimental results showed that SQC model established by response values of all samples could show the change law of odor in Crataegi Fructus stir-fried process and changes of 5-HMF content was dropped after the first increase. Correlation analysis showed that the odor change in Crataegi Fructus stir-fried process and 5-HMF were significantly correlated (P < 0.05). Sugar degradation reaction and the Maillard reaction may be one of the mechanisms of the odor change in Crataegi Fructus stir-fried process.

Objective To investigate the status of the disease of the fluorosis and arsenism caused by coal-burning in Ankang city of Shaanxi. Methods Nine survey spots were chosen to carry out the epidemiological investigation of adult skeletal fluorosis and arsenism in the coal-polluted areas of Ankang, respectively using Determination of Fluorine in Coal (GB/T 4633-1997) to determine the coal fluorine and using hydride generation atomic fluorescence spectrophotometry(HCAFS) to determine coal arsenic. The diagnose of the adult skeletal fluorosis followed the Diagnosis of Clinical Classification for Endemic Skeletal Fluorosis Standard(GB 16396-1996), that of arsenism using Standard of Diagnosis for Endemic Arsensim (WS/T 211-2001). Results Totally 569 adults were investigated over the age of 16, among which 121 cases were skeletal fluorosis, with a total detection rate of 21.27%. Four cases of II degree and higher skeletal fluorosis patients were identified, accounting for 0.70% of the number of subjects. One hundred and thirty-two cases of arsenic poisonin were detected, in a rate of 23.20%. Ninety-five patients were identified with moderate or severe arsenic poisoning, accounting for 16.69% of subjects. A positive correlation was found between the detection rates of the skeletal fluorosis and the arsenism(r = 0.816, P < 0.01), as well as between the detection rate of skeletal fluorosis and fluoride content of coal(r = 0.775, P < 0.05). The detection rate of arsenism and arsenic content of coal also had close relationship (r = 0.761, P < 0.05). The detection rate of skeletal fluorosis in the group aged 40 - ,50 - , and 60 - [27.20%(34/125) ,29.27%(36/123), 28.13%(36/128)] was increased, compared the group of less than 40 years age[7.77%( 15/193), X~2 = 21.969,25.648,23.856,P<0.01].For the detection rate of arsenism,male[33.67%(99/294)]was obviously higher than female[12.00%(33/275),)(X~2=37.162,P<0.01].Conclusions A high detection rate of fhorosis is correlated with arsenic poisoning,but the probability of the two diseases simultaneously occurred in a person is not high.In this polluted area.when fluoride accumulates to a certain level as in aduh,the detection rates no longer varies obviously;however,that of arsenism increases along with the age.

OBJECTIVETo study the factors affecting the management and treatment of immigrant workers with tuberculosis, to determine the most effective measures and to provide an academic basis for tuberculosis control and prevention strategies targeting the immigrant population.
METHODSA self-designed questionnaire was administered to 1364 immigrant workers with tuberculosis (study group) and 436 local residents (control group) with tuberculosis.
RESULTSWhether a patient's tuberculosis status was discovered or not was related to the medical facilities initially visited, job mobility, and the individual worker's economic condition. The percentage of cases discovered was relatively low among those who made their first visit to a private clinic (39.0%), and 58.4% (796) of immigrant workers delayed their first consultation mainly due to neglecting symptoms (55.9%, 445), subjective perception of symptoms being not severe enough (19.3%, 154) to visit a physician and the inconvenience of visiting a hospital because of its being far away from home (15.8%, 47). As comparing immigrant workers with local residents, the differences of the delay reason between the two groups were statistically significant (chi(2) = 21.49, P < 0.01). And 39.9% (544) of immigrant workers and 49.1% (214) of local residents had had late confirmation. The differences of the delay reasons between the two groups were insignificant (chi(2) = 7.31, P = 0.293). And 17.6% (240) patients of immigrant workers and 13.1% (57) patients of local residents did not keep to their drug regimens in a timely fashion. The differences of the reasons between the two groups were insignificant (chi(2) = 6.66, P > 0.05). And 77.5% (1057) of immigrant workers and 31.8% (138) of local residents were considered that taking medicine in supervision spot might have impact on their lives and work. The differences of the reasons between the two groups were significant (chi(2) = 9.71, P < 0.05). All 79.2% (1080) of immigrant workers and 63.3% (276) of local residents did not obtain medicine according to prescriptions. The differences of reasons between the two groups were statistically significant (chi(2) = 24.84, P < 0.01). And 51.2% (699) of immigrant workers and 46.1% (201) of the registered population did not follow up with doctors' directions for lab tests. The differences of the reasons between the two groups were insignificant (chi(2) = 3.26, P > 0.05).
CONCLUSIONThe influential factors in tuberculosis management and treatment were complex. Prevention strategies should focus on health education and promotion activities to improve awareness in seeking medical services. Also, developing and standardizing reference mechanisms for patients, and alleviating the economic burden of the workers will be critical to reduce the tuberculosis incidence.

OBJECTIVETo explore the application of caffeine-halothane contracture test (CHCT) in the confirmation of malignant hyperthermia (MH).
METHODSOne patient who underwent radical gastrectomy presented with clinical manifestations of MH during routine intravenous-inhalation anesthesia process. Isoflurane inhalation and the operation were ceased immediately and emergency management approaches such as physical cooling therapy were taken. Meanwhile, the levels of serum creatine kinase (CK), serum myoglobin, and urinary myoglobin were examined and rectus abdominis was taken and then CHCT was performed to confirm the clinical diagnosis. Total genome was extracted from the patient and then exons 2-18, 39-46, and 90-104 of ryanodine receptor 1 (RYR1) gene were screened to detect mutations using DNA sequencing technique.
RESULTSThe patient was diagnosed as MH episode by clinical characteristics and postoperatively continuous elevation of the levels of CK, serum myoglobin, and urinary myoglobin (30 times higher than normal level). Despite halothane test was negative, the diagnosis of MH was verified by the positive result of caffeine test. DNA sequencing of RYR1 gene of the patient revealed c. 6724C > T (p. T 2 206M).
CONCLUSIONCHCT can be used to confirm the diagnosis of MH.
