OBJECTIVETo compare the results of application of Qu single abdominal aorta clamping for bloodless hepatectomy and Pringle hepatectomy in 118 cases of liver tumors.

METHODSThe clinical data of 118 patients, including 59 patients undergoing Qu single abdominal aorta clamping for bloodless hepatectomy (Group QG) and 59 patients undergone Pringle first hepatic portal clamping hepatectomy (Group PG) since March 2009 in the Ningbo Tumor Hospital and Jiangxi Provincial Hospital were retrospectively reviewed. The changes of blood pressure, oxygen saturation, urine volume, intravenous fluid volume, amount of bleeding, time of abdominal aorta (or first hepatic portal) clamping, duration of operation and anesthesia, and other intraoperative indexes of the two groups were compared, and the changes of peritoneal drainage, blood tests, liver functions, etc. before operation and 1, 3, 7, 14 days after the hepatectomy in the two groups were also analyzed.

RESULTSAfter taking appropriate measures for intraoperative blood pressure control, only small fluctuations of blood pressure, which could be safely adjusted and controlled with stable vital signs, was observed in the group QG. The amount of intraoperative bleeding in the group QG was (96.25 ± 18.45) ml, significantly less than (536.25 ± 35.65) ml in the group PG (P < 0.05). In the group QG, both the duration of operation time [(227.58 ± 28.20) min] and duration of anesthesia [(249.48 ± 31.35) min] were significantly shorter than that [(261.46 ± 32.12) min and (286.58 ± 35.62) min, respectively] in the group PG (both P < 0.05). The postoperative liver dysfunction in the group QG was also milder than that in the group PG (P < 0.05).

CONCLUSIONSFor liver tumor patients, Qu single abdominal aorta clamping for bloodless hepatectomy can basically achieve the goal of bloodless hepatectomy. This surgical operation is simple and safe, worthy of recommendation to skillful liver surgeons in hospitals there are some difficulties of blood supply.

OBJECTIVETo observe the clinical efficacy of integrative medical therapy in treating post-craniocerebral traumatic mental disorder (PCT-MD).

METHODSSixty patients with confirmed diagnosis of PCT-MD were randomly assigned to the treated group and the control group equally. All were treated by conventional comprehensive Western medicine, but to patients in the treated group, modified Xufu Zhuyu Decoction (XFZY) was additionally given and the therapeutic course for both groups was 20 days. Changes in mental symptoms were observed and recorded on the 10th and 20th day and clinical efficacy as well as cranial CT image was estimated after termination of the treatment.

RESULTSThe clinical effective rate in the treated group and the control group was 96.67% and 83.30% respectively. Comparison between them showed significant difference (P<0.05). Significant differences were also shown in the comparisons between the two groups in improving mental symptoms, either on the 10th or on the 20th day (P<0.05 and P<0.01 respectively), and in post-treatment cranial CT image (P<0.05).

CONCLUSIONBetter efficacy could be obtained by integrative medical therapy in treating PCT-MD.

OBJECTIVETo study the effect of extraneous p53 gene with deletion of c-terminal 356 - 393 amino acids on inhibition of malignant phenotype of human lung cancer cell line.

METHODSRecombinant plasmid pEGFP-p53 (del) with codon deletion of c-terminal 37 amino acids from 393 to 356 region and pEGFP-p53 (wild type) were constructed. The human lung cancer cell line 801D served as a receipt cell had p53 deletion and mutation at 248 codon. 801D cells, having been transfected by pEGFP-p53 (wild type), pEGFP-p53 (del) or pEGFP, were selected by G418. Growing transfected cells were cloned respectively by method of dilution. Presence of extraneous gene was detected by PCR, their expression in cells was examined by fluorescence microscopy. Cloning efficiency was in vitro tested to examine the cellular proliferating ability. The xenograft in nude mice was performed and xenograft tumors were weighed one month later. Expression of GFP in tumor and transplanted cellular mass were detected by blot slices.

RESULTSpEGFP-p53 (del)-801D, pEGFP-p53-801D and pEGFP-801D were established. Extraneous p53 gene and expression of GFP were found in pEGFP-p53 (del)-801D and pEGFP-p53-801D. Inhibitory rate of colony was 99.6% for pEGFP-p53 (del)-801D and 81.0% for pEGFP-p53-801D. Inhibition of malignant proliferation of extraneous p53 (del) was higher than that of p53 (wild type) (P < 0.01). Even when inhibition of malignant proliferation extraneous pEGFP-p53 (del) was obvious, 0.2% colonies were formed, extraneous p53 and expression of GFP were observed. Animal test showed that tumor on the nude mice was positive (4/4, 4/4) in the control group (801D and pEGFP-801D), but negative (0/4, 0/4) in the experiment group [pEGFP-p53 (del) 801D and pEGFP-p53 (wild type) 801D]. Expression of GFP in the cells of cellular mass transplanted by pEGFP-p53 (del) 801D or pEGFP-p53 (wild type) 801D was observed.

CONCLUSIONIn vitro inhibitory effect of extraneous p53 gene with deletion of C-terminal 356 - 393 amino acids on malignant growth of lung cancer cell with p53 mutation or deletion at 248 codon is marked. Inhibitory action of p53 on malignant proliferation of cancer cells is heterogeneous.

OBJECTIVETo study the changes of platelet in May-Hegglin anomaly (MHA) and the molecular pathogenesis mechanism.

METHODSPeripheral blood was drawn from the MHA proband, her father and her uncle. Platelet count and morphology were examined by automatic blood cell counter and microscopy, respectively. The platelet membrane protein was examined by flow cytometry. Membrane antibodies were determined by ELISA. PCR was used to amplify the exons 25, 31 approximately 32, 38 and 40 of the MYH 9 gene in the MHA patient and her diseased father. Furthermore, PCR products were sequenced, a specific point mutation was identified and inclusions (Dohle's body) in the neutrophil was detected by indirect immunofluorescence technique.

RESULTSIt was proved that in MHA patients, platelet count was higher by cell counter than by microscope (P < 0.01). Giant platelet was 94% but platelet membrane proteins (CD41, CD61, CD42A, CD42b) were in normal range. Membrane antibodies was undetectable. An A5521G mutation (GAG-->AAG) in the exon 38 was found in the proband and her diseased father, resulting in a characteristic change of NMMHC-A1841 (Glutamic acid-->Arginine), which was not found in other members of the family and in normal controls. Spindle-like inclusions with fluorescence were clearly displayed in neutrophil cytoplasm.

CONCLUSIONThe molecular pathogenesis mechanism of May-Hegglin anomaly is the mutation in MYH 9 gene.

Objective To compare the actions of Longbie Capsules and bone marrow mesenchymal stem cell (BMSC)transplantation in repairing the damaged cartilage of knee osteoarthritis(KOA)rats. Methods Thirty-six rats aged 4-6 weeks old were induced into KOA model(bilateral knees)by collagenase injection method. All of the modeled rats were randomly divided into model group(intragastric administration of normal saline), BMSC transplantation group(giving tail vein injection of 1 ×106 of BMSCs per time, 2 times every week), and Chinese medicine group (intragastric administration of Longbie Capsules of 7.5 g·kg-1·d-1),12 rats in each group. Six weeks later,the cartilage of rat bilateral knees was taken out. The pathological changes of cartilage were observed by hematoxylin-eosin(HE) staining method, and the protein and mRNA expression levels of Col2a1, X-linkedinhibitor of apoptosis protein (XIAP), HuR in rat knee cartilage were detected by immunohistochemistry and real-time quantitative polymerase chain reaction (qPCR), respectively. Results The HE staining results showed that the cartilage tissue surface was rough with more cracks, and the cartilage cells gathered with the cytoplasm collapsed and arranging disorderly in the model group. The number of chondrocytes was increased and cell surface was flat,and the cracks of the cartilage were decreased with the chondrocytes arranging uniformly in Chinese medicine group and BMSC transplantation group compared with the model group. The results of immunohistochemistry and qPCR detection showed that in Chinese medicine dosage group and BMSC transplantation group, the protein and mRNA expression levels of Col2a1,XIAP and HuR were significantly higher than those in the model group (P<0.05 or P<0.0001), but there was no significant difference between the two medication groups(P>0.05). Conclusion Longbie Capsules and BMSC transplantation can promote the secretion of Col2a1 in the cartilage tissue of KOA rats,improve cartilage, and their mechanism may be related with up-regulating apoptosis-related proteins HuR and XIAP.

The rapid and accurate authentication of traditional Chinese medicines(TCMs)has always been a key scientific and technical problem in the field of pharmaceutical analysis.Herein,a novel heating online extraction electrospray ionization mass spectrometry(H-oEESI-MS)was developed for the rapid and direct analysis of extremely complex substances without the requirement for any sample pretreatment or pre-separation steps.The overall molecular profile and fragment structure features of various herbal medicines could be completely captured within 10-15 s,with minimal sample(＜0.5 mg)and solvent consumption(＜20 μL for one sample).Furthermore,a rapid differentiation and authentication strategy for TCMs based on H-oEESI-MS was proposed,including metabolic profile characterization,characteristic marker screening and identification,and multivariate statistical analysis model validation.In an analysis of 52 batches of seven types of Aconitum medicinal materials,20 and 21 key compounds were screened out as the characteristic markers of raw and processed Aconitum herbal medicines,respectively,and the possible structures of all the characteristic markers were comprehensively identified based on Com-pound Discoverer databases.Finally,multivariate statistical analysis showed that all the different types of herbal medicines were well differentiated and identified(R2X＞0.87,R2Y＞0.91,and Q2＞0.72),which further verified the feasibility and reliability of this comprehensive strategy for the rapid authentication of different TCMs based on H-oEESI-MS.In summary,this rapid authentication strategy realized the ultra-high-throughput,low-cost,and standardized detection of various complex TCMs for the first time,thereby demonstrating wide applicability and value for the development of quality standards for TCMs.

"Huangbo" is a commonly used traditional Chinese medicine in clinic,which is mainly divided into " Chuanhuangbo" and " Guanhuangbo" in the market today. It's better to use thick and dark stem bark as medicine. This study combed the germplasms of " Huangbo" in Chinese herbal medicines and ancient medical books,which showed that the name,origin and processing of " Huangbo" had undergone evolution and changes since the ancient times. The results showed that " Huangbo" was first known as " Bomu" from " Sheng Nong's Herbal Classic". There was an attached name " Tanhuan" and the alias " Huangbo" besides " Bomu" in herbal books in Tang and Song Dynasty. Before Tang Dynasty, " Bomu" was mainly originated from stems or roots of Berberis species in Berberiaceae,and then it was mainly derived from the dry bark of Phellodendron chinense in Rutaceae since Song Dynasty. In Ming Dynasty,some herbal books recorded it name as " Huangbo",whose origin and medicinal parts remained unchanged,taking Sichuan as the best producing area. During the Republic of China era,the name " Huangbo" has evolved to " Huangbo",and the variety differentiation of " Chuanhuangbo", " Guanhuangbo" and " Yanghuangbo" appeared,in which " Guanhuangbo" was mainly derived from Ph. amurense Rupr.. In modern times,although species differentiation still exists in " Huangbo",the market is still dominated by " Chuanhuangbo".

Visci Herba， a commonly used Chinese medicinal， was often mistaken as Taxilli Herba in ancient Chinese materia medica. The two Chinese medicinals have often been confused even in present clinical practice， and their origins are difficult to be identified. Hence， it is necessary to carry out systematic and in-depth textual research. This paper explored the origin， producing area， quality evaluation， harvesting and processing， property， flavor， and efficacy of Visci Herba based on ancient Chinese materia medica of the past dynasties and modern plant morphology， so as to provide evidence for the development and utilization of Visci Herba. The findings demonstrated that Visci Herba was mostly recorded as Taxilli Herba until the name of Visci Herba appeared in the Tang Dynasty. The records of the two Chinese medicinals could be traced back to the Song Dynasty. Visci Herba and Taxilli Herba were officially listed as two different Chinese medicinals in the 1977 edition Chinese Pharmacopoeia for the first time， where the origin of Visci Herba was determined to be Viscum coloratum（Komar.）Nakai. According to the ancient Chinese materia medica， V. coloratum was mainly distributed in Lingbao， Henan province and Xuzhou， Jiangsu province and now it mostly grows in Northeast China and North China. In ancient times， Visci Herba with deep yellow cross-section and sticky fruit juice on the tree was preferred， which was often harvested on 3， March in spring， dried in the shade， grinded together with the roots， branches， stems， and leaves using the copper file， and preserved away from fire. By contrast， it is now usually harvested from winter to the next spring and then cut into sections for drying after the removal of thick stems， or dried after being steamed. As described in ancient Chinese materia medica， Visci Herba， bitter and sweet in flavor， neutral in property， possessed the effects of dispelling rheumatism， tonifying kidney， strengthening sinews and bones， benefiting blood vessels， and preventing abortion， basically consistent with its modern functions of dispelling rheumatism， tonifying liver and kidney， strengthening sinews and bones， and preventing abortion.

The commodity specification and grade is an important factor affecting the price of Chinese medicinal materials. Specification and grade standard play an important role in transferring quality information in Chinese medicinal market, which is characterized by highly information asymmetry. This paper analyses and expounds six classification methods of commodity specification and grade of Chinese medicinal materials based on the market investigation carried out in the medicine markets in Anguo, Bozhou, Yulin, Chengdu and so on. This study proposes that to formulate the commodity specification and grade standard of Chinese medicinal materials, their efficacy, inspection, purity and beauty should be taken into account orderly.
