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.

Objective To study the epidemiological and clinical characteristics of patients with severe acute respiratory syndrome(SARA). Methods Clinical data from 682 patients with SARS were retrospectively analyzed. Results The patients ranged from 13 to 76 years old, 387 male and 295 female. A total of 356 patients (52.2) had a history of close contact with diagnosed SARS patients, and 113 (25.1%) had been to hospital ever. The most common symptom was fever (99.3%), followed by cough (44.4%), shortness of breath (12.2% ), diarrhea (8.9%). 596 patients (87.4%) had normal or decreased white blood cell counts. Serum ALT and CPK levels were elevated in 112 patients (16.4%)and 17 patients (2.5%) respectively. Infiltrates on chest radiography were seen in all patients, with 69.8% involved both lungs. Six patients (0.9%) died of SARS. Conclusion SARS is infectious. Hospital is an important place where SARS transmits. Fever, cough and infiltrative changes on chest radiography are mainly symptoms and signs.

Objective; To evaluate the effects of gingival shade guide in visual shade-matching in vitro models. Methods; 42 tabs of Shofu NCC shade guide were adopted for color measuring. Each tab was fixed in the middle of Gingiva-Indicator, Guray(1,2,3,4) respectively and located in a black box. The measurements were made using the Shadepilot instrument. The color parameters ( CIE1976L * a * b * ) of cervical, body, incisal area of each tab were recorded. The color difference A E value in the same position of each tab was calculated between non-gingival shade guide group and Gumyl ,2,3,4 groups with Shadepilot software. Results; The AE value in the same position of 42 tabs between non-gingival shade guide group and 4 gingival shade guide groups were; cervical (2.93±0.79)NBS,body(0.51±0.27)NBS and incisal(0.61 ±0.29)NBS. In the cervical, body and incisal area, there was no statistically difference among Gumyl ,2,3,4 groups on affecting shade of tabs(P >0. 05). Conclusion; The gingival color has an effect on the cervical shade of tabs, and it can be recognized by human eyes, while gingival color has little effect on the shade of body and incisal area.

The morphological, cultural and biochemical characteristics of the bacterium were studied. The indigo pigment was also extracted. The results showed that the maximum absorption peak of the pigment was at 579nm. The pigment was stable to UV, Na_2SO_3,It was also stable at pH 3～9. The pigment was unstable to the sunlight and high concentration H_2O_2. Temperature of 60℃～80℃ could increase the hue while temperature higher than 90℃ could reduce the hue.

Objective:To investigate the clinical effects of autologous platelet rich plasma gel (PRP) combined with vacuum sealing drainage (VSD) technology on the repair of refractory wounds.Methods:From March 2011 to January 2015, 44 patients with refractory wounds and conformed to the inclusion criteria were included into VSD alone group, who were admitted to the Department of Burn and Plastic Surgery of the Yidu Central Hospital of Weifang and received intermittent VSD treatment. From February 2015 to September 2019, 43 patients with refractory wounds and conformed to the inclusion criteria were included into PRP+VSD group, who were admitted to the same unit above-mentioned and received PRP combined with intermittent VSD treatment.The retrospective cohort study was conducted. There were 24 males and 20 females with ages of (37.5±2.2) years in VSD alone group, and there were 25 males and 18 females with ages of (37.0±2.5) years in PRP+VSD group. The wound secretions of patients in the two groups before and 7, 14 d after the first treatment were collected for bacterial culture, and the positive rate of bacterial culture was calculated.The wound healing of patients in the two groups was observed on 7, 14,and 21 d after the first treatment, and the wound healing rate was calculated. The complete wound healing time of patients in the two groups was recorded. The degree of wound pain of patients in the two groups was evaluated by the visual analog scale (VAS) before and 14 d after the first treatment. The scar hyperplasia of patients in the two groups was evaluated by the Vancouver Scar Scale (VSS) in 1 and 2 months after the wound healed completely.The incidence of adverse reactions of patients in the two groups after the treatment was observed and the incidence of adverse reactions was calculated.Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, paired t test, and Bonferroni correction.Results:The positive rates of bacterial culture of patients in PRP+VSD on 7 and 14 d after the first treatment were 37.2% (16/43) and 11.6% (5/43), which were significantly lower than 56.8% (25/44) and 29.5% (13/44) in VSD alone group, χ2= 4.212, 4.255, P<0.05. The wound healing rates of patients in PRP+VSD group on 7, 14 and 21 d after the first treatment were (58±14)%, (70±13)%, (89±12)%, which were significantly higher than (41±11)%, (60±11)%, (74±12)% in VSD alone group, t=6.323, 3.820, 5.751, P<0.01. The complete wound healing time of patients in PRP+VSD group was (30±6) d, which was significantly shorter than (61±8) d in VSD alone group, t=20.89, P<0.05. The VAS score of patients in PRP+VSD group was significantly lower than that in VSD alone group (t=13.904, P<0.01). The VSS score of patients in PRP+VSD group was significantly lower than that in VSD alone group in 1 and 2 months after the wound healed completely (t=3.307, 3.637, P<0.01). The incidence of adverse reactions of patients in PRP+VSD group after the treatment was 7.0% (3/43),which was significantly lower than 22.7% (10/44) in VSD alone group alone, χ2=4.245, P<0.05. Conclusions:Autologous PRP gel combined with VSD technology to repair refractory wounds not only has good bacteriostatic effect, but also can increase wound healing rate, shorten wound healing time, reduce wound pain, relieve scar hyperplasia, and without adverse reactions, which is worthy of promotion.
