Objective: To research the best processing method for ginger pinellia by orthogonal tests.Methods: The orthogonal tests included the soaking time, boiling water and cooking time as the influencing factors, an HPLC method was used for the determination of 4 nucleosides (uridine, guanosine, adenosine, inosine), and the alum limit and extract content were also studied.The results were evaluated by multi index comprehensive weighted score to optimize the processing technology of ginger pinellia.Results: The best processing technology of ginger pinellia was as follows: soaked for 60 hours, the proportion of boiling water and pinellia tuber was 15:1, and boiled for about 5 h.Conclusion: The optimum processing technology of ginger pinellia is reasonable, reliable and reproducible, which can be used as the reference for the processing standardization of Chinese crude drugs.

OBJECTIVETo observe the efficacy of Jianbu Tongluo Xunzheng Liquid (JTXL) in treating knee osteoarthritis (KOA), and to explore the correlation between changes of infrapatellar fat pad scanned by CT and the efficacy.
METHODSTotally 105 KOA outpatients were randomly assigned to three groups, i.e., the treatment group, the control group, and the combination group, 35 in each group. Patients in the treatment group were fumigated by JTXL, 30 min each time, once daily, 10 times as a course of treatment, 3 courses in total. Those in the control group received intra-articular injection of Sodium Hyaluronate Injection (SHI), 3 mL each time, once per 6 days, 5 times in total. Those in the combination group were treated by fumigation of JTXL + intra-articular injection of SHI in the same way as the aforesaid two groups. All patients were treated for 30 days. Their clinical efficacy and changes of infrapatellar fat pad scanned by CT were observed, and their correlation was analyzed.
RESULTSThe total effective rate was 88.57% in the combination group, better than that of the control group (74.29%) and the treatment group (80.00%; both P < 0.05). Besides, the score for knee joint functions at Hospital for Special Surgery (HSS) was better in the combination group than the other two groups (P < 0.05). The anteroposterior diameter, exterior-interior diameter, the superior-inferior diameter were shortened, and the density decreased in the treatment group and the combination group (P < 0.05). Besides, they were superior to those of the control group (P < 0.05).
CONCLUSIONSChanges of infrapatellar fat pad scanned by CT only existed in the combination group and the treatment group, indicating changes of CT scanning was only correlated with effect on changing physicochemical properties of infrapatellar fat pad. Treatment by Chinese medicine could omnipotently and balanced regulate functions and structures of every tissue. Therefore, CT could be taken as a better method for clinical efficacy observation by Chinese medicine.

OBJECTIVE:
Preliminary assessment of rabies virus neutralizing activity, safety and immunogenicity of a recombinant human rabies antibody (NM57) compared with human rabies immunoglobulin (HRIG) in Chinese healthy adults.
METHODS:
Subjects were randomly (1:1:1) allocated to Groups A (20 IU/kg NM57), B (40 IU/kg NM57), or C (20 IU/kg HRIG). One injection was given on the day of enrollment. Blood samples were collected on days -7 to 0 (pre-injection), 3, 7, 14, 28, and 42. Adverse events (AEs) and serious AEs (SAEs) were recorded over a period of 42 days after injection.
RESULTS:
All 60 subjects developed detectable rabies virus neutralizing antibodies (RVNAs) (> 0.05 IU/mL) on days 3, 7, 14, 28, and 42. The RVNA levels peaked on day 3 in all three groups, with a geometric mean concentration (GMC) of 0.2139 IU/mL in Group A, 0.3660 IU/mL in Group B, and 0.1994 IU/mL in Group C. At each follow-up point, the GMC in Group B was significantly higher than that in Groups A and C. The areas under the antibody concentration curve over 0-14 days and 0-42 days in Group B were significantly larger than those in Groups A and C. Fifteen AEs were reported. Except for one grade 2 myalgia in Group C, the other 14 were all grade 1. No SAEs were observed.
CONCLUSION
The rabies virus neutralizing activity of 40 IU/kg NM57 was superior to that of 20 IU/kg NM57 and 20 IU/kg HRIG, and the rabies virus neutralizing activity of 20 IU/kg NM57 and 20 IU/kg HRIG were similar. Safety was comparable between NM57 and HRIG.
