With the improvement of cataract operation, the cataract surgery has become increasingly perfect. The cataract patients show greater expectation for the result of cataract operation. As a result, refractive cataract surgery has become the main trend. Detailed investigations of corneal diseases, lens density, corneal topography, preferable intraocular lens ( IOL ) choice, and IOL power calculation can help us get a better knowledge of preoperative conditions on patients, which can be conducted with pentacam. So we can have a better forecast of post - operative outcome and improve the quality of vision for cataract patients after surgery.

In the clinical skill evaluation,SP and the new technology OSCE for medical educational evaluation brought by SP can offer a vivid and complete exam atmosphere for the medical students,which have been widely applied by medical colleges and schools at home and abroad,with real,effective,reliable characteristics and broader development prospect. To induce the technology into TCM clinical evaluation is in accordance with the requirements of TCM educational development,which can make students better grasp clinical various basic skills within limited studying periods.

Objective] Making a discussion on academic features ofYi Lin Kou Pu Liu Zhi Mi Shu. [Method] With the research methods of philology, we collect Qing transcript ofYi Lin Kou Pu Liu Zhi Mi Shuand analyze its academic features. [Result]Yi Lin Kou Pu Liu Zhi Mi Shuwas additionally compiled, supplemented and annotated by Zhou Sheng, a famous doctor of the Qing Dynasty, on the base of Yi Lin Kou Pu which was composed by Lu Qi. Within four volumes, the contents of the book contain Medicine, Surgery, Gynecology, Pediatrics, etc. The diagnosis and treatment based on syndrome differentiation and Chinese herbal prescription in this book have their own characteristics. That is: theories from different schools make arguments on the facts; six treatments of syndrome lucidly expose the essential points; secret prescriptions and Chinese herbs are widely collected; opinions and knowledge from his teacher grasp the essence of the problem and bring out the crucial point. [Conclusion]Yi Lin Kou Pu Liu Zhi Mi Shu is a distinctive and only existing medical book with high academic value and practical significance.

objective: To observe the distribution of pegylated liposmal doxorubicin(PLD) in animal model of tongue cancer. Methods: Tongue cancer model was established in 40 golden hamster, PLD or free doxorubicin at the dose of 9 mg/kg was injected perifocally into each of 20 mice, the concentration of the drugs in lypmph node and blood was measured with HPLC. Results: After injection of free ADM peak concerntration in blood was acheived in 3 h and in lymph nodes in 1 h, while after injection of PLD, that was in 16 and 6 h respectively. The concertration of PLD was heigher than that of ADM in both blood and lymph node from 16 or 6 h till 216 h after injetion.Conclusion: PLD can be regarded as valuable drug delivery system in the treatment of oral cancer.

Objective To compare the therapeutic efficacy between laparoscopic peritoneal vaginoplasty and sigmoid loop vaginoplasty. Methods A total of 29 cases of congenital absence of vagina received either laparoscopic peritoneal vaginoplasty (Peritoneal Group, 14 cases) or sigmoid loop vaginoplasty (Sigmoid Group, 15 cases) from March 1998 to April 2003. Results The operation failed in 1 case in the Peritoneal Group, requiring a conversion to open sigmoid loop vaginoplasty. Both groups had no surgical complications or postoperative pyrexia. The operating time of the Peritoneal Group (118 9?19 0 min) was significantly shorter than that of the Sigmoid Group (202 0?18 6 min) ( t =-11 674, P =0 000). And the intraoperative blood loss of the former (36 2?12 6 ml) was significantly less than that of the latter (105 3?46 3 ml) ( t =-5 205, P =0 000). The conditions of reconstructed vagina of both groups were basically the same, but the vagina length of the Sigmoid Group (10 8?1 1 cm) was significantly greater than that of the Peritoneal Group (9 0?0 8 cm) ( t =-4 882, P =0 000). Among the Sigmoid Group, 3 cases had somewhat more amount of vaginal secretion and 4 cases had abnormal-smelling secretion. Patients in both groups reported the same satisfactory degree of sexual life. Conclusions Laparoscopic peritoneal vaginoplasty and sigmoid loop vaginoplasty present a similar therapeutic efficacy, but the former gives less surgical invasion than the latter.

[ABSTRACT]OBJECTIVETo investigate the cytomegalovirus infection in neonates, characteristics of gap junction protein Connexin26 gene mutation and the hearing follow-up results, and to analyze their correlations. METHODS60 CMV-DNA positive and 40 CMV-DNA negative neonatal newborn from The Second Affiliated Hospital of Wenzhou Medical University and The first people's Hospital of Yongkang were screened, the blood biochemistry was analyzed, and the umbilical cord blood was reserved to detect the Connexin26 gene expression of mRNA with RT-PCR.PCR results was sequenced to track the newborn hearing, and analyze the correlations between neonatal cytomegalovirus types, the mutation of Connexin26 gene and hearing test results.RESULTS 26 cases from 60 CMV-DNA positive newborns were found with blood biochemical abnormalities. In all of the newborns, a total of 41 cases had 235delC mutation, 11 cases in the mutations for the development of hearing impairment. The results of correlation analysis showed that there were correlations between cytomegalovirus infection, gene mutation and hearing impairment.CONCLUSION Cytomegalovirus infection in neonates can lead to mutations in the Connexin26 gene, and may further lead to hearing impairment, and the probability of the mutation of Connexin26 gene and sensorineural hearing loss were higher in symptomatic cytomegalovirus infection neonates.

Bone marrow mesenchymal stem cells (BMSCs) are a kind of pluripotent stem cells derived from bone marrows, which can not only support hematopoiesis, but also have capabilities of multidifferentiation, high-proliferation and self-renewing. They have become one of hotspots in stem cell studies. Studies on in vitro intervention with BMSCs with TCMs have made remarkable progress in recent years. According to the findings, some traditional Chinese medicines can promote proliferation of BMSCs, some can inhibit the apoptosis of BMSCs, while others can induce BMSCs to differentiate into multiple cell types, such as osteoblast. Furthermore, some studies also involved relevant action mechanisms. The authors summarized the advance in relevant studies by reference to relevant literatures of this field.

Objective To study the effects of cripto on migration, invasion, and liver metastasis of colorectal cancer cell. Methods After human colorectal cancer cell line SW480 was transfected by cripto small interfering RNA (siRNA), the mRNA and protein level were determined by Real-time RT-PCR and Western blot, respectively. The migration and invasion ability were evaluated by wound-healing assay and boyden chamber model, respectively. Thirty nude mice model of liver metastasis from colorectal cancer was established by splenectomy. Results The siRNA could down-regulate the level of mRNA and protein of cripto in a dose- and time-dependent manner. Suppression of cripto expression could inhibit migration and invasion ability of human colorectal cancer cell in vitro. The metastastic rate and tumor nodules were lower in transfection with cripto siRNA than in two control groups in vivo. Conclusions Cripto gene might play an important role in regulation of liver metastasis from colorectal carcinoma cell, and suppression of cripto gene by siRNA can inhibit liver metastasis of colorectal cancer.
