OBJECTIVEFor optimizing the cutting process of Radix Isatidis, the influence of cutting process on the whole chemical constituents was studied by comparing the difference of HPLC fingerprints of Radix Isatidis from various sources before and after cutting.

METHODL9(3(4)) orthogonal table were designed with three factors: The amount of solvent, soaking time and thickness of pieces. According to the amount of water-soluble extraction, orthogonal design was applied to processing; Fingerprints of acetoacetate extraction from 9 batches of Radix Isatidis from various sources before and after cutting were established with a High Performance Liquid Chromatography method based on a Agilent Zorbax SB-C18 column (4.6 mm x 250 mm, 5 microm) with gradient elution solvent system composed of acetonitrile-water solution; the detection wave length was set at 238 nm; sample injection was 10 microL. The fingerprints were compared with similarity evaluation software published by the Committee of China Codex.

RESULTThe best process of cutting was following: the amount of solvent was 0.6 times of amount of Radix Isatidis, soaked for 24 h and the thickness of piece was 2 mm.

CONCLUSIONThe obvious difference is displayed by the comparing of HPLC fingerprints. It is indicated that the constituents in polarity medium lost a lot after cutting process.

Objective To evaluate the clinical outcomes of locking plate combined with allogenic fibular intramedullary support in the elderly patients with varus proximal humeral fracture.Methods From May 2015 to July 2017,21 elderly patients with varus proximal humeral fracture were treated with locking plate combined with allogenic fibular intramedullary support at Department of Orthopaedics,The Second Clinical Medical College,Guangzhou University of Traditional Chinese Medicine.They were 6 men and 15 women,from 65 to 90 years of age (average,74.8 years).According to the Neer classification,2-part fracture was identified in 2 patients,3-part fracture in 14 and 4-part fracture in 5.Their operation time,amount of intraoperative bleeding,postoperative complications and functional scores at the last follow-up were recorded.The humeral neck angles and humeral head heights were compared between preoperation,postoperation and the last follow-up.Results Their operation time averaged 89.5 minutes (from 70 to 110 minutes) and intraoperative bleeding 179.5 mL (from 160 to 400 mL).They obtained follow-up from 12 to 26 months (average,18.1months).All the wounds were healed by the first intention.No such complications occurred as neurovascular lesion,shoulder dislocation or humeral head necrosis.However,screw cut-out was observed in one case.According to the Neer's scoring system,shoulder function was evaluated at the last follow-up as excellent in 3cases,as good in 15 and as fair in 3,giving a good to excellent rate of 85.7％.The humeral neck angle after operation was 136.4° ± 5.8°,significantly larger than the preoperative one (106.0° ± 7.3°) (P ＜0.05) but insignificantly different from the value at the last follow-up (135.4° ±6.5°) (P ＞ 0.05).The postoperative distance between the plate top and the humeral head top was 1.6± 0.2 mm,insignificantly different from that at the last follow-up (1.5 ± 0.2 mm) (P ＞ 0.05).Conclusion Locking plate combined with allogenic fibular intramedullary support can effectively reconstruct the medial proximal column of the humerus,restore the humeral neck angle,facilitate intraoperative fracture reposition and reduce operation time,leading to good functional recovery of the shoulder and prevention of related complications.

Ovarian cancer （OC） is a common gynecological malignant tumor in clinical practice. In the early stage，it is often asymptomatic，while in the late stage，it mainly presents with non-specific symptoms such as abdominal distension，poor appetite，and dull abdominal pain. Some patients may also have cachexia such as weight loss and anemia. Early diagnosis is difficult，and the mortality rate ranks first among gynecological malignant tumors，making OC a major challenge in clinical treatment. The classic Chinese medicine formula Guizhi Fulingwan comes from the Jingui Yaolue and has the effects of promoting blood circulation，removing blood stasis，and reducing abdominal lumps. In recent years，it has been widely used to treat OC with good results. This article summarized the clinical application of Guizhi Fulingwan in the treatment of OC from two aspects：The analysis of its basic prescriptions and clinical research. In terms of basic prescriptions，the formula has the ability to promote blood circulation，remove blood stasis，and reduce abdominal lumps. It can exert therapeutic effects considering both water and blood aspects and reduce abdominal lumps， with characteristics of simultaneous Yang warming and heat clearing and parallel supplementation and elimination. Through the methods of "circulation" and "supplementation"， it strengthens the body，dispels evil，and eliminates underlying symptoms. In clinical studies，Guizhi Fulingwan can be applied to various stages of patients with OC，which not only promotes the recovery of the body after OC surgery but also can be combined with chemotherapy and immunotherapy to synergistically treat advanced OC and enhance treatment efficacy. In addition，the formula can also alleviate various adverse reactions caused by chemotherapy，with high safety，improve patients' quality of life，prolong survival，and optimize tumor control effects. Based on the above analysis，this article elaborated on the current clinical research status of Guizhi Fulingwan combined with Western medicine in the treatment of OC and proposed suggestions and improvements to address the shortcomings in current clinical research，so as to provide reference for the clinical application of this formula in the treatment of OC and the construction of a combined traditional Chinese and Western medicine treatment model.
