Abstract: Objective To investigate the differences in epidemiological and clinical characteristics of patients with spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS). Methods A total of 86 patients with SF and 113 patients with SFTS who were laboratory-confirmed in the second-level and above hospitals in Lu'an City from January 2017 to January 2022 were selected. The basic data, epidemiological history, clinical data and laboratory test results of the two diseases were retrospectively analyzed for comparison. Results The proportion of male in SF group was 32.56% (28/86), and the proportion of male in SFTS group was 53.98% (61/113), the difference was statistically significant (χ2=9.067, P<0.01). The proportions of abdominal pain and diarrhea in the SF group were (3.49%, 3/83) and (21.24%, 24/113), which were significantly lower than corresponding (6.98%, 6/86) and (46.90%, 53/113) in the SFTS group (χ2=13.121, 37.322, P<0.01). The incidences of rash and eschar in SF group were 95.35% (82/86) and 20.93% (18/86), which were significantly higher than corresponding 1.77% (2/113) and 0.88% (1/113) in SFTS group (χ2=175.311, 22.721, P<0.01). The levels of leukocytes, platelets and C-reactive protein in the SF group were significantly higher than those in the SFTS group, and the levels of transaminase, lactate dehydrogenase and D-dimer were significantly lower than those in the SFTS group, and the differences were statistically significant (all P<0.05). Conclusions The rash and inflammatory reaction are more obvious in SF patients, while the liver function, myocardial function and coagulation function are significantly impaired in SFTS patients.

Knee osteoarthritis is a common disease, and also one of the acupuncture advantage treatment disease. Usually the clinicians choose local acupoints based on the characteristics of tendon bone and joint. After a long-term clinical practice, we found that the curative effect could be better if we additionally combine with the abdominal acupoints. We regard this as the breakthrough point to explore the theoretical origin and found that the curative effect of taking the “biao”or“jie” acupoints to treat disease of the limbs is better than just taking the acupoints according to channel tendon therapy. In this paper, we started discussing the basic meaning of “biao”“ben”“gen”“jie”,then studied the relationship between the vertical connection of“biao”“jie” with blood lifting in disease and qi jie playing as a channel in theory. Comparing with clinical report , I proposed the view which is to choose the points of “biao”“ben”to treat limbs disease. This view enriches the theory of acupoints of the treatment of pain diseases, and expends the clinical acupoints in the treatment of osteoarticular diseases.

Aim To study the effects of cycle arrest and molecular mechanism in human leukemia HL-60 cells induced by diallyl disulfide ( DADS ) . Methods Cell count, colony formation in soft agar experiments and flow cytometry analysis were employed to observe the DADS-induced cell growth inhibition and the effect of cycle arrest in HL-60 cells. The expressions of Chk1/2 and its downstream element in HL-60 cells were detected by Western blot. Results Cell count revealed that population doubling time increased to 35. 03 h and 71. 82 h, respectively, from 19. 14 h in HL-60 cells treated with 60 and 120 μmol·L-1 DADS ( P<0. 05 ) . Colony formation in soft agar experiments showed that colony formation inhibition rate of HL-60 cells exposed to 30, 60, 90 and 120μmol·L-1 DADS increased to 35. 06%, 62. 10%, 93. 79% and 99. 35%, respectively ( P<0. 05 ) . Flow cytometry a-nalysis exhibited that HL-60 cells treated with 60 and 120 μmol · L-1 DADS for 24 h and 48 h arrested in G2/M phase in a concentration-and time-dependent manner ( P <0. 05 ) . Western blot disclosed that the expression of p-Chk1 increased in a time-dependent manner ( P <0. 05 ); however, Chk1, Chk2 and p-Chk2 were not changed in HL-60 cells treated with 60μmol·L-1 DADS (P >0. 05). The expression of Cdc25C, CyclinB1 and CDK1 decreased after treated with 60 μmol·L-1 DADS in a time-dependent manner ( P<0. 05 ) , but the expression of 14-3-3 protein did not change ( P>0. 05 ) . Conclusion DADS can in-hibit the proliferation of HL-60 cells, and induce G2/M arrest through Chk1/Cdc25 C/CyclinB1/CDK1 path-way.

Objective To investigate association between human leukocyte antigen DQB1 (HLADQB1 ) gene polymorphisms and bronchial asthma among Mongolian and Han nationalities. Methods Sequence-specific primer polymerase chain reaction (PCR-SSP) was used to detect frequencies of HLA DQB1 genotypes and alleles in 50 cases of Han and 68 Mongolian asthmatic patients, and 50 Han and 54 Mongolian healthy controls, respectively. Difference in gene frequencies between the two nationalities was estimated by odds ratio (OR) and chi-square test. Results Frequency of the HLA-DQB1 0602 allele was significantly higher in Han patients with bronchial asthma than that in healthy Han nationality (OR = 6.163,P ＜0.01 ). Frequency of the HLA-DQB1 0603/0608 allele decreased in Mongolian asthmatic patients, as compared to that in healthy Mongolians ( OR = 0.199, P ＜ 0.05 ). Frequency of the HLA-DQB1 0301/4 allele was significantly higher in Mongolian asthmatic patients as compared to that in healthy Mongolians ( OR =2.074,P ＜0.05). Frequency of the HLA-DQB1 0301/4 allele was significantly higher in Mongolian than that in Han asthmatic patients ( OR = 2.482 ,P =0.05). Frequency of the HLA- DQB1 0602 allele was significantly higher in healthy Mongolians than that in healthy Han nationality ( OR = 3.341, P ＜ 0.05 ), in contrast, frequency of the HLA-DQB1 0402 allele was significantly lower in healthy Mongolians than that in healthy Han nationality ( OR = 0.209, P ＜ 0.05 ). Conclusions The HLA-DQB1 0603/0608 allele is possibly a protective gene and the HLA-DQB1 0301/4 allele a susceptible gene for bronchial asthma in Mongolians, and the HLA-DQB1 0602 allele is possibly a susceptible gene for bronchial asthma in Han nationlity.

OBJECTIVETo observe the effect of alcohol extracts from Pharbitidis Semen on the proliferation and metastasis of Lewis lung cancer, and study its anti-tumor mechanism.

METHODIn vitro, MTT assay and scratch assay were adopted to detect the effect of alcohol extracts from Pharbitidis Semen on the proliferation and metastasis of Lewis lung cancer cells. The cell autophagy was detected by the acridine orange staining. The gap-junction intercellular communication (GJIC) was investigated by the fluorescent yellow transfer. The expression of aquaporin 1 (AQP1) was analyzed by the Western blotting. In vivo, the subcutaneous implant model and the experimental pulmonary metastasis model of Lewis lung cancer in mice were established to evaluate the anti-tumor and anti-metastasis effects of alcohol extract from Pharbitidis Semen. The serum carcinoembryonic antigen (CEA) and beta2 microglobulin (beta2-MG) of mice bearing Lewis lung cancer were detected by the electrochemiluminesence immunoassay. The expressions of lung AQP1 and Connexin 43 (Cx43) were examined by the immunohistochemical method.

RESULTIn vitro, alcohol extracts from Pharbitidis Semen inhibited the cell proliferation in a dose-dependent matter, significantly prevented the cell migration, down-regulated AQP1 proteins of cells, promoted GJIC, and decreased the serum-free autophagy of tumor cells. In vivo, compared with untreated model mice, alcohol extracts from Pharbitidis Semen inhibited the tumor growth in a dose-dependent matter, prevented the tumor metastasis and prolonged the life span of mice bearing Lewis lung cancer, while decreasing serum CEA and beta2-MG of mice bearing Lewis lung cancer, enhancing the immumohistochemical staining intensity of Cx43 and weakening aquaporins AQP1 positive intensity.

CONCLUSIONAlcohol extracts from Pharbitidis Semen could prevent the proliferation and metastasis in Lewis lung cancer cells. Its mechanism may be related to the promotion of GJIC and the down-regulation of AQP1.
