OBJECTIVETo assess the effects of LiCl on prostate cancer growth and to explore the underlying mechanisms.

METHODSEffects of LiCl on cell growth in vitro and in vivo were determined by cell counting and xenografts of prostate cancer cells. Alterations in cell proliferation and the expression of DNA replication-related protein were determined by MTT assay, BrdU incorporation and Western blot.

RESULTSCompared to PBS control group, the number of prostate cancer cells (PC-3) were lower treated with 10 mmol/L LiCl, the number was 1.9×10(5), 4.8×10(5) and the difference was significant (P < 0.05). The inhibition rate of cellular proliferation were 50%, 95% and 98%, respectively, in LiCl group, NaCl and KCl control group, the difference was significant (P < 0.05). The A-Value of BrdU incorporation was 1.5, 1.3 treated with 10 mmol/L, 30 mmol/L LiCl, while the A-value of BrdU incorporation was 4 in PBS control group, the difference was significant (P < 0.05). On the protein level, LiCl downregulates expression of cdc 6, cyclins A and cyclins E, and cdc 25C, and upregulates expression of the CDK inhibitor p21(CIP1). The mean volume and weight of xenograft tumor were 50 mm(3) and 296 mg after LiCl intraperitoneal injection, But PBS control group were 180 mm(3) and 957 mg, the difference was significant (P < 0.05).

CONCLUSIONLiCl disrupts DNA replication and suppresses tumor growth of prostate cancer cells in vitro and in vivo.

Compounds from Lingzhi has been demonstrated the ability for inhibiting tyrosinase (a key enzyme in melanogenesis) activity. In this study, we investigated the anti-melanogenic activity from the submerged mycelial culture of Ganoderma weberianum and elucidated the skin lightening mechanism by B16-F10 murine melanoma cells. From the cellular context, several fractionated mycelium samples exhibited anti-melanogenic activity by reducing more than 40% extracellular melanin content of B16-F10 melanoma cells. In particular, the fractionated chloroform extract (CF-F3) inhibited both secreted and intracellular melanin with the lowest dosage (25 ppm). Further analysis demonstrated that CF-F3 inhibited cellular tyrosinase activity without altering its protein expression. Taken together, our study has demonstrated that the chemical extracts from submerged mycelial culture of G. weberianum have the potential to serve as an alternative anti-melanogenic agent.

Insulin-like growth factor binding-protein-7 (IGFBP7) was obtained from our previous colonic adenocarcinoma (CRC) and normal mucosa suppression subtraction hybridization (SSH) cDNA libraries. By RT-PCR and immunohistochemistry, we found that IGFBP7 was overexpressed in CRC tissue compared to normal tissue. However, our in vitro experiments performed in 10 CRC cell lines showed that IGFBP7 expressed only in SW480 and Caco2 cell lines, which implied an underlying reversible regulatory mechanism. Using methylation-specific PCR (MSP) and bisulfite sodium PCR (BSP), we found that its expression was associated with DNA hypomethylation of exon1. This was further supported by the in vitro study which showed restored IGFBP7 expression after demethylation agent 5-aza-2'-deoxycytidine treatment. Correlation analysis between IGFBP7 expression and prognosis indicated that overexpression of IGFBP7 in CRC tissue correlated with favourable survival. Investigation of the functional role of IGFBP7 through transfection studies showed that IGFBP7 protein could inhibit growth rate, decrease colony formation activity, and induce apoptosis in RKO and SW620 cells, suggesting it a potential tumor suppressor protein in colorectal carcinogenesis. In conclusion, our study clearly demonstrated that IGFBP7 plays a potential tumor suppressor role against colorectal carcinogenesis and its expression is associated with DNA hypomethylation of exon 1.

OBJECTIVETo summarize the experience of surgical resection of 103 hilar cholangiocarcinoma.

METHODSOne hundred and three consecutive cases of hilar cholangiocarcinoma who underwent surgical resection at our hospital over the past ten years were reviewed retrospectively. The clinical data and long-term outcome were analyzed.

RESULTSOut of 103 cases, 43 patients underwent radical resection (41.7%), and 60 patients underwent palliative resection. There were 34 patients developed postoperative complications and 8 patients died in hospital. For the radical resection group, the median survival time was 29.9 months and 1-year, 3-year, 5-year survival rate was 69.6%, 42.0%, 20.9%, respectively, which was significant greater than 34.1%, 10.2%, 0 of the palliative resection group (P < 0.05). Over the past five years, 42 cases underwent pre-operative drainage of bile and the rate of combined liver resection reached 53.8%. The tumor radical resection rate has increased to 45.7%, the median survival time have reached 24.7 months (P < 0.05).

CONCLUSIONSImprovement of pre-operative management, intraoperative pathology for resection margin, and combined liver resection may help in increasing the radical resection rate. Radical resection can improve postoperative survival, and produce a satisfactory outcome for patient with hepatic hilar cholangiocarcinoma.

Objective To investigate the clinical effect of laparoscopic and open radical resection of hilar cholangiocarcinoma (Bismuth-I). Methods From January 2011 to January 2017, 34 patients (10 patients in the laparoscopic group and 24 patients in the open group) underwent radical resection of hilar cholangiocarcinoma. Their clinical data were analyzed retrospectively. Results All these patients underwent radical resection of hilar cholangiocarcinoma of type Bismuth-I successfully. The volume of blood loss was (179.50 ± 98.05) ml and duration of hospital stay was (11.80 ± 2.49) d of laparoscopic group which was lower than (261.25 ± 97.33) ml, (16.25 ± 3.35) d of open group (P < 0.05). The levels of Tbil of laparoscopic group at days after operation 1, 3, 5 d were (102.20 ± 45.49) mmol/L, (83.57 ± 30.66) mmol/L, (45.09 ± 18.41) mmol/L. The levels of Tbil of open group at days after operation 1, 3, 5 d were (148.17 ± 62.78) mmol/L, (121.60 ± 43.35) mmol/L, (80.59 ± 43.89) mmol/L. The difference was statistically significant (P < 0.05). And the laparoscopic group postoperative number of lymph nodes dissected (9.79 ± 3.05), postoperative complications (1 cases), positive margin (0 cases); and open group(9.30 ± 3.06), 3 cases, had no statistically significant differences were compared (P >0.05). Two groups of patients were followed up for 6~18 months. During the follow-up period, there was no recurrence or metastasis in the two groups. Conclusion Laparoscopic Bismuth-I radical resection of hilar bile duct carcinoma in lymph node dissection, postoperative complications, positive margin rate, prognosis and open type Bismuth-I hilar cholangiocarcinoma radical operation of similar effects, and more minimally invasive advantages. Therefore, laparoscopic radical resection for hilar cholangiocarcinoma of type Bismuth-I is safe and feasible.

Objective To evaluate the effect of the rehabilitation software based on information-motivation-behavioral skills(IMB)model on meeting the rehabilitation needs, increasing the continuation of rehabilitation and the rehabilitation compliance, improving the outcome of rehabilitation among elderly patients with fracture. Methods Based on the theory of"information-motivation-behavior"and the unity of human- computer interaction as the design concept, the status quo of rehabilitation training and rehabilitation needs of elderly patients with fracture were reviewed. The rehabilitation training test was applied to 30 patients with fracture in orthopedic department of our hospital. 30 patients in the same period were randomly selected as control group. All patients underwent Self-Rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores before and 1 and 3 months after operation. Differences were tested using Student's t test. Results Developed rehabilitation application software based on information module、motivation module and behavior module. The test group using this software for rehabilitation training was compared with the control group. The results showed that there was no significant difference in preoperative SAS and SDS scores between the two groups (t=-0.648,-0.284, P>0.05). At 1 and 3 months after operation, the SAS scores in the test group were (40.05 ± 6.77), (32.01 ±5.86), which were lower than (45.50 ± 11.32), (39.55 ± 5.67) in the control group (t=-4.14,-4.89, P<0.01). The SDS scores in the test group were (42.30 ± 9.86), (33.23 ± 6.56), which were lower than (46.50 ± 10.32), (38.45 ± 7.80) in the control group (t=-3.52,-3.82, P=0.001). Conclusion Rehabilitation software can influence the rehabilitation behavior of elderly fracture patients from information and motivation factors, provide professional guidance and rehabilitation intervention, and promote the implementation of active rehabilitation.

Danshen has a long history in China as a commen traditional Chinese medicine, but many other members of the Salvia family is also used as Danshen in particular regions. The name of Danshen were analyzed according to the color, efficacity and etc. To investigate the real origin of Danshen, the stalk, leaf, flower and radix in chronicle and pictures of ancient literature were deciphered. It showed that in the past dynasties, Salvia miltiorrhiza was the most likely plant used as Danshen. The rigin and quality evaluation of Danshen were also summerized, provided new insight and proof for the development and utilization of Danshen.

Ginger is commonly used as dietetic Chinese herbs, medicinal ginger mainly divided into dried ginger, fresh ginger and baked ginger. In this article, by sorting and studying literature of Chinese materia medica, textual criticism the historical evolution and change of differentiation on dried ginger, fresh ginger and baked ginger. Results indicate that, as the changes of the dynasty, dried ginger, fresh ginger and baked ginger gradually differentiation in producing area and processing method. Dried ginger beginning in Shennong Bencao Jing（Shennong's Classic of Materia Medica）, Mingyi Bielu（Records of Famous Physicians） respectively included fresh ginger and dried ginger for the first time. Dried ginger and fresh ginger differentiation in producing area. Between the period of Shennong Bencao Jing（Shennong's Classic of Materia Medica）and Bencao Gangmu（Compendium of Materia Medica）, dried ginger was made from fresh ginger by water, peeled and sunlight; After Bencao Gangmu（Compendium of Materia Medica）, most herbalists support the view of Li Shizhen, thought that dried ginger was made by mother ginger. Baked ginger appeared in Han Dynasty. Depei Bencao（De Pei Materia Medica） in Qing Dynasty listed the baked ginger separately as a herb medicine ingredient, thought that baked ginger was made by dried ginger. As the changes of the dynasty, genuine producing areas of ginger were changed, but mainly concentrated in Yangtze river basin. Sichuan Qianwei is the main authentic region of modern medicinal ginger, in accordance with all previous dynasties materia medica. Since the Ming Dynasty, a lot of herbalists thought that good quality of dried ginger is meat thick full, color white and texture solid.

BACKGROUNDBlepharophimosis ptosis epicanthus inversus syndrome (BPES) is a rare congenital ophthalmic disorder, characterized by congenital eyelid malformation including bilateral ptosis, shortening of the horizontal eyelid fissure, epicanthus inversus, and increased distance between the inner canthi. In this research, we studied the histological structure and ultrastructure of medial canthal ligament of patients with BPES.

METHODSThirty patients with BPES who received plastic surgery at the Zhongshan Ophthalmic Center from March 2006 to January 2008 were studied. There were 17 males and 13 females with an average age of (8.73 +/- 3.37) years (3 - 31 years). The medial canthal ligaments of patients were collected during the plastic surgery to analyze the histological structure by hematoxylin and eosin (HE), Congo red, van Gieson's (VG), Masson trichrome and aldehyde-fuchsin staining. The ultrastructures of the medial canthal ligaments were also analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Fifteen samples of medial canthal ligament from healthy persons with an average age of (9.02 +/- 3.12) years (6 - 30 years) were collected as a control group.

RESULTSMorphological and histological study showed that the medial canthal ligaments of BPES patients were composed of collagen fibers, a few elastic fibers and striated muscles. The collagen fibers assemblies were disorganized and the fibrous connective tissues were undergoing hyaline degeneration. The karyopycnosis of fibroblasts was located among the collagen fibrils and the numbers of fibroblasts were decreased. Ultrastructural study with SEM showed that the collagen fibers were larger than normal, irregular and loose. Parts of the collagen fibers were broken and had a coarse surface. Ultrastructural study with TEM showed that the fibroblasts had less cytoplasm, fewer organelles and the nucleus displayed pyknosis.

CONCLUSIONSThe medial canthal ligament in BPES patients is composed chiefly of collagen fibers. The collagen fibers of medial canthal ligaments in BPES patients are disorganized and hyaline degeneration is present. The study revealed that the medial canthal ligament of BPES patients might have congenital dysplasia.
