OBJECTIVETo investigate the effects of the ultra-filtration extract mixture from Hedysarum Polybotrys (UEMHP) on the radiosensitivity of HepG2 cells, and to explore its possible mechanisms.

METHODSThe proliferation inhibition effects of UEMHP on HepG2 cells was detected by CCK-8 assay. The colony formation assay was used for the survival fraction (SF) analysis. The distribution of the cell cycle and the apoptosis rate were detected using flow cytometry (FCM). The survivin mRNA expression level was detected using reverse transcription-PCR assay.

RESULTSThe inhibition of UEMHP on HepG2 cells was time-and dose-dependent at the concentration ranging between 5 -50 mg/L (P < 0.05). The parameters of the two curve for SF (P < 0.05) showed statistical difference between the irradiation group and the UEMHP irradiation group. UEMHP could inhibit the clone formation of HepG2 cells and enhance the radiosensitivity of HepG2 cells. The results of FCM showed that UEMHP could induce G2/M phase arrest. The apoptosis rate in the UEMHP irradiation group (21.42% +/- 3.74%) was higher than that in the control group (5.35% +/- 0.41%), the only UEMHP group (10.36% +/- 1.75%), or the irradiation group (10.58% +/- 2.01%) (P < 0.01). RT-PCR showed that the survivin mRNA expression level was lower in the UEMHP irradiation group (0.31 +/- 0.02) than in the control group (0.82 +/- 0.06) and the irradiation group (0.58 +/- 0.04) respectively, showing statistical difference (P < 0.01).

CONCLUSIONUEMHP can enhance the radiosensitivity of HepG2 cells, and its possible mechanisms might be correlated to down-regulating the survivin mRNA expression and promoting the apoptosis.

OBJECTIVETo investigate the expression of Toll-like receptors (TLRs) in thymus of myasthenia gravis (MG) patients and the relationship with clinical features.

METHODSThymic specimens of 36 patients received extended thymectomy for MG were divided into three groups by pathological type: 13 thymoma tissues (thymoma group) and 13 thymic tissues adjacent to thymomas (parathymoma group) from 13 cases of MG patients with thymomas, and 23 thymic tissues from MG patients without thymomas (MG nonthymoma group). Twenty-one normal thymic specimens from cardiac surgery were used as controls. The levels of TLR2-4 mRNA were examined by RT-PCR, then the levels of TLR4 mRNA were assayed by real time RT-PCR and their relationship with clinical features were analyzed.

RESULTSThe levels of TLR4 mRNA among the different groups had significant differences, while there was no difference in TLR2 and TLR3 levels. The real time RT-PCR showed that the level of TLR4 mRNA in nonthymoma group was significantly higher than that in control group(0.8544+/- 0.1200 vs 0.6851+/- 0.1524, P=0.018). And so is parathymoma group compared with the thymoma group (0.8214+/- 0.1019 vs 0.7101+/- 0.0916, P=0.005). No significant difference of TLR4 mRNA level was found between the parathymoma and nonthymoma groups. Nevertheless, the expression of TLR4 in both groups was increased compared with control group. The levels of TLR4 mRNA had positive correlation with Osserman type(R=0.609; P=0.004) .

CONCLUSIONTLR4 may play a key role in the pathogenesis of MG. It was the thymic tissues adjacent to thymomas but not thymomas themselves participated in the onset of MG.

OBJECTIVESTo observe the clinical outcome of invasive thymoma, and analyze how the surgical methods, Masaoka staging, adjuvant radiotherapy and/or chemotherapy affect the prognosis.

METHODSThe clinical data of 59 surgical patients with invasive thymoma and conducted follow-up from January 2000 to December 2009 was analyzed retrospectively. There were 34 male and 25 female, aged from 18 to 72 years with a mean age of 49 years. Forty-four cases underwent radical resection while the other 15 cases underwent palliative resection or biopsy. Masaoka staging: 18 cases with stage II, 30 cases with stage III, 11 cases with stage IV. Patients with stage II didn't undergo further adjuvant radiotherapy or chemotherapy after surgery. Among the patients with stage III and stage IV, 26 patients received adjuvant radiotherapy and/or chemotherapy after surgery, while the other 15 patients did not receive any further therapy. The relationship between the prognosis and the different surgical methods, Masaoka staging, adjuvant radiotherapy and or chemotherapy was evaluated.

RESULTSFifty-nine patients had been followed up for 1 to 111 months with an average of 54 months. Three cases were lost with the rate of 6.1%. Nineteen patients suffered local recurrence or systemic metastasis, and 14 of them died. The 3-year and 5-year survival rates were 86.8% and 70.8% respectively. Univariate analysis indicated that patients with early Masaoka staging and who received radical resection, adjuvant radiotherapy and/or chemotherapy after surgery had better survival (P < 0.05). Multivariate analysis indicated that radical resection, adjuvant radiotherapy and or chemotherapy were the most significant prognostic factors which could remarkably improve the survival of patients (P < 0.05). For patients with resectable recurrence, reoperation could also improve survival.

CONCLUSIONSThe Masaoka staging is related to the prognosis of patients with invasive thymoma. Radical resection, adjuvant radiotherapy, chemotherapy can significantly improve the survival of patients with invasive thymoma. Reoperation can improve the survival of some patients with recurrence.

OBJECTIVETo analyze the learning curve of single-direction complete video-assisted thoracoscopic surgery (cVATS) for lung cancer.

METHODSFrom May 2006 to April 2009, 125 cases of cVATS for lung cancer were performed by two dedicated surgeons. Clinical data were collected prospectively and analyzed retrospectively. The patients operated by different surgeon were divided into 2 groups (group A, n = 24; group B, n = 101), and group B was further divided sequentially into 4 subgroups (B1, B2, B3 and B4) by the number of patients. The patients in group A and B were operated by the surgeons with 2-year and 5-year experience of VATS respectively. The operating time, blood loss, number of resected lymph nodes (NLN), rate of thoracotomy conversion (RTC) and postoperative complications (POC) were compared.

RESULTSCompared with group B, the operating time of group A was significantly prolonged [(237 ± 85) min vs. (187 ± 43) min, P = 0.013], but there were no significant differences in blood loss, NLN, RTC and POC. Comparing group A with B1, the same results were got. From group B1 to B4, the operating time was gradually reduced and blood loss decreased, but the difference was not statistically significant. And in group B, there was a significant reduction of blood loss for the last 51 cases compared to the first 50 cases [(122 ± 141) ml vs. (87 ± 81) ml, P = 0.009].

CONCLUSIONSAt the early stage of cVATS resection of lung cancer, the duration of operation was longer, which it was more significant for the surgeons with short carrier of thoracoscopic experience. But the morbidity of operation related complications did not increase. The indicator of proficiency in this operation is achievement of 50 cases of complete thoracoscopic resection of lung cancer.

During 2 years,a 6-year-old girl was hospitalized for 2 times with recurrent onset of episodes of vomiting,weakness and fever after eating dessert at the Department of Neurology & Endocrine Pediatrics,the Affiliated Hospital of Qingdao University.The arterial blood gas analysis revealed severe hypoglycemia,lacticacidemia and metabolic acidosis,the urine ketone body was positive.After intravenous infusion of glucose,bicarbonate and antibiotics,there was a dramatic clinical improvement in a short time.Physical examination showed tachypnea and mild hepatomegaly,and she had normal physical and mental development.The laboratory findings revealed transient hyperuricacidemia.Urine organic acids analysis repeatedly showed an elevation of lactic acid,ketone and glycerol.Glyceroluria was a very distinctive trait.The literatures in PubMed was searched with glyceroluria as keyword.Three related diseases were identified:FBPase deficiency,glycerol kinase (GK) deficiency and complex GK deficiency.Further reading of related literatures to understand the characteristics of diseases and laboratory tests,the clinical diagnosis of GK deficiency and complex GK deficiency was excluded.The mutation analysis of FBPase gene (FBP1) was performed by Sanger sequencing and a novel compound heterozygous mutations of c.355G ＞A and c.960delG was discovered.Full analysis of disease-related traits and targeted gene testing is one of the effective methods for accurate diagnosis and treatment of inherited metabolic disorders.

OBJECTIVETo assess the metastatic frequency in different groups of lymph nodes and its influencing factors of the thoracic esophageal squamous cell carcinoma (ESCC) in order to determine the extent of lymphadenectomy during esophagectomy.

METHODSThe clinical data of 730 patients with ESCC who underwent esophagectomy and lymphadenectomy were analyzed retrospectively.

RESULTSOf 730 patients, 166 had metastasis to the para-esophageal lymph nodes (22.7%), 90 to the left gastric artery lymph nodes (12.3%), 67 to the lymph nodes around gastric cardia, and 15 to the subcrinal lymph nodes (2.1%). Univariate analysis showed that metastasis to the subcrinal lymph node was positively correlated with the length and differentiation of tumor (P < 0.05), but it was not correlated with any the above parameters when analyzed by multivariate analysis. The metastasis to the para-esophageal lymph node was positively correlated with the length, invasion depth and differentiation of tumor by univariate and multivariate analysis (P < 0.05). The metastasis to the lymph nodes around gastric cardia and metastasis to left gastric artery lymph nodes were positively correlated with the position and invasion depth of tumor by univariate and multivariate analysis (P < 0.05).

CONCLUSIONLymph nodes of the para-esophagus, gastric cardia and left gastric artery usually have high frequency to harber mestastasis, therefore, it was suggested that the lymph nodes in these groups should be dissected during esophagectormy with two-field lymphadenectomy for thoracic esophageal squamous cell carcinoma. Whereas for those patients with the lesion < 3 cm in length or with tumor invasion confined within the esophageal wall or with a lesion located at the upper or lower third of the thoracic esophagus, the subcrinal lymph nodes may not be necessarily dissected.
