OBJECTIVETo study the inhibitory effect of Xiaotan Sanjie Recipe (XSR) on the microsatellite instability of orthotopic transplantation tumor in MKN-45 human gastric cancer nude mice.

METHODSThe 3rd passage subcutaneous transplantation tumor was taken as the origin of the model by using MKN-45 human gastric cancer cell lines. MKN-45 human gastric cancer nude mouse model was established using OB glue adhesive method. Then 30 nude mice were divided into the model group, the XSR group, and the chemotherapy group. Mice in the XSR group were intragastrically given XSR at the daily dose of 0.4 mL. Mice in the chemotherapy group were intragastrically given Fluorouracil at the daily dose of 0.4 mL. No intervention was given to mice in the model group. After 6 weeks of medication, the tumor weight was measured, and the tumor inhibition rate calculated. The size, the peak height, and the peak area of 5 microsatellite instability sites were detected.

RESULTSThe tumor inhibition rate was 40. 84% in the XSR group. The tumor weight was significantly lower in the XSR group than in the model group (P < 0.01), showing no statistical difference when compared with the chemotherapy group (P >0.05). The incidence of high microsatellite instability (MSI-H) in the model group was 70%, and the incidence of low microsatellite instability (MSI-L) was 30%. Microsatellite stable site tended be stable after 6 weeks of XSR treatment.

CONCLUSIONXSR showed inhibition on microsatellite instable orthotopic transplantation tumor in MKN-45 human gastric cancer nude mice.

OBJECTIVETo study the effect of Xiaotan Sanjie Recipe (XTSJD) and its mechanism on vasculogenic mimicry (VM) of human gastric cancer xenografts in nude mice.

METHODSThe tumor-bearing mice model was established by subcutaneous inoculating with xenografts of human gastric cancer into the right armpit of 30 BALB/c nude mice. After modeling, the tumor-bearing mice were randomly divided into the normal saline group, the XTSJD group, and the doxycycline hyclate (DH) group, 10 in each. And the mice were administered with corresponding medicine by gastrogavage for 4 weeks. Then all mice were killed by cervical dislocation. The tumor mass were weighed and the tumor inhibition rate calculated. The amount of VM in tumor was counted. Expressions of matrix metalloproteinase (MMP) -2 and MMP-9 were tested using immunohistochemical method.

RESULTSTumor weight in the XTSJD group and the OH group decreased significantly when compared with the NS group (P<0.01). The amount of VM in the XTSJD group (24.50+/-3.03) and the OH group (14.70+/-1.34) was significantly less than that in the NS group (33.10+/-2.64) (P<0.01). The positive expressions of MMP-2 and MMP-9 in the XTSJD group and the OH group was significantly lower than that in the NS group (P <0.01).

CONCLUSIONXTSJD could inhibit the formation of VM in xenografted tumor of nude mice. The mechanism might be correlated with the down-regulation of MMP-2 and MMP-9 expressions.

OBJECTIVETo observe the effect of activation of aldehyde dehydrogenase 2 (ALDH2) by ethanol on the expression of c-Jun N-terminal kinase (JNK) in the kidney of diabetic rats.

METHODSEightheen healthy male SD rats were randomly divided into 3 groups (n = 6): normal control group, diabetes group and ethanol + diabetes group. After 8 weeks, 24 h urine samples from rats were collected to detect urinary protein content. The kidney was isolated and the ratio of kidney weight/body weight (index of kidney weight) was detected. The levels of fasting blood glucose, glycosylated hemoglobin serum urea nitrogen and serum creatinine were measured. Morphological changes of renal tissue were observed by optical microscope. The protein expressions of ALDH2 and JNK in renal tissue were detected by Western blot.

RESULTSCompared with the normal control rats, the levels of fasting blood glucose, glycosylated hemoglobin, serum urea nitrogen, serum creatinine and the index of kidney weight were increased markedly in diabetic rats. The expression of ALDH2 protein was decreased, while p-JNK, JNK protein expressions and the ratio of p-JNK/JNK were increased. The morphological observation was shown that the amount of glomerular mesangial matrix were increased, basement membrane were thickened and capillary lumen were narrowed. However,in ethanol + diabetes group, renal function was improved and the damage of renal structure was attenuated. The expression of ALDH2 protein was increased, while p-JNK, JNK and the ratio of p-JNK/JNK were decreased.

CONCLUSIONEnhanced ALDH2 expression can protect kidney in diabetic rats, which may be relevant with inhibitting the activity of JNK pathway.

OBJECTIVETo observe the mechanism of Xiaotan Sanjie Recipe (XSR) in inhibiting lymphatic metastasis of gastric carcinoma by observing its effects on the expressions of vascular endothelial growth factor-C (VEGF-C) and its receptor VEGFR-3 in nude mice with transplanted human gastric adenocarcinoma cell MKN-45.

METHODSThirty mice were made into MKN-45 tumor model and randomly divided into three groups treated with saline, 5-Fu, and XSR, respectively. Gene and protein expressions of VEGF-C and VEGFR-3 in the tumor tissue were detected by RT-PCR, and the lymphatic microvessel density (LMVD) in tumor was measured with immunohistochemistry.

RESULTSCompared with the group treated with saline, the mRNA and protein expressions of VEGF-C and VEGFR-3 as well as LMVD level were significantly lower (P < 0.05 or P < 0.01) in the group treated with XSR. There was no significantly statistic difference between the group of XSR and 5-Fu on the indices mentioned above (P > 0.05).

CONCLUSIONBy down-regulating the mRNA and protein expressions of VEGF-C and VEGFR-3 might be one of possible mechanisms for XSR in preventing and curing the lymphatic metastasis of gastric carcinoma.

Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%–6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneously. A 61-year-old male patient was admitted to our hospital for a 4 cm×2.5 cm growing tumor in a verrucous form arising within a periauricular nevus sebaceus in the post auricle of the left ear that had developed 30 years earlier. The nodule was diagnosed as 3 different types of tumors: trichilemmoma, desmoplastic trichilemmoma, and basal cell carcinoma. To our knowledge, this is the first report of the coexistence of three different tumors arising from nevus sebaceous. It contain malignant neoplasm also. Surgeons should be aware of the need for close monitoring and early complete surgical excision of sebaceous nevus in order to improve patient outcomes.
