Objective To assess the therapeutic efficacy of a recombined adenovirus expressing p53 (rAd-p53) via intrapleural injec-tion in the treatment of lung cancer with malignant pleural effusion. Methods Thirty-six cases with lung cancer and malignant pleural effu-sion were randomly divided into two groups,which were given intravenous injection of Nedaplatin with (observation group,n=20) or without (control group,n=16) intrapleural injection of rAd-p53,respectively. Between the two groups,the efficacy in treatment of pleural effusion, the amelioration of maximal ventilatory volume ( MVV) ,Kamofsky scoring ( KPS) and quality of life were compared. Results The efficacy in treatment of pleural effusion in observation group are significantly higher than that in control group(17/20 vs. 50%,P<0. 05). The cases with KPS≥80 in observation group were significantly increased following treatment (5/20 vs. 11/20,P <0. 05). However,there was no difference with the cases in control group. Conclusion Intrapleural injection of recombinant adenovirus expressing p53 (rAd-p53) is effec-tive to reduce the occurrence of malignant pleural effusion and increase the quality of life remarkably.

OBJECTIVETo establish the theories and methods to determine apparent solubility paraneters of multiple components for the Chinese materia medica (CMM) with HPLC fingerprint.

METHODThe mathematical functional expresses to determine the apparent solubility parameters for multiple constituents were established according to total quantum geometrical average retention time (TQGART) for HPLC fingerprint that characterized the entirety tendencies for all-over chromatographic peaks, validated by the aloe-emodin's solubility parameters which had been determined. The HPLC for the aloe-emodin's solubility parameters were carried out with an Alltech Apollo C18 as column, Acetone: Water as mobile phase, gradient elution,flow rate as 1.0 mL x min(-1), the detection wave-length as 430 nm and the temperature as 30 degrees C.

RESULTThe mathematical functional model between the TQGART of HPLC chromatographic fingerprint and the total quantum apparent solubility parameters was established and used to determine the aloe-emodin's mixture solubility parameter as 36.12 J(1/2) x cm(-3/2), nearly equal to 35.57, 36.07 J(1/2) x cm(-3/2) calculated by ration of peak area ratios and molecular fraction, respectively.

CONCLUSIONThe TQGART of HPLC fingerprint can be used to determine simultaneously the apparent or single intrinsic solubility parameters for total quantum or intrinsic solubility parameters for single in multiple constitute systems, by which theoretical and technologic platform to study the compatibility rule and dosage form reform of the single CMM will be established.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.
