The oral administration of bioactive macromolecular drugs such as proteins, peptides and nucleic acids represents unprecedented challenges from the drug delivery point of view. One key consideration is how to overcome the gastrointestinal tract absorption barrier. Recent studies suggest that microfold cell (M cell), a kind of specialized antigen-sampling epithelial cell which is characterized by a high endocytic rate and low degradation ability, may play an important role in macromolecule oral absorption. The development of an in vitro M cell coculture system and its modified models greatly advanced the study of M cells and the development of oral delivery system for macromolecular drugs. The special structure, function and formation characteristics, and biomarkers of M cell are summarized in this review. The applications of in vitro M cell models in developing oral delivery system ofbioactive macromolecular drugs are discussed.

Objective:To explore the effectof tumor volume on pulmonary dose-volume parameters by intensity-modulated radiation therapy (IMRT) in non-small cell lung cancer (NSCLC),and to provide a basis for pulmonary dose parameters in IMRT treatment.Methods:A total of 204 patients with NSCLC received IMRT were retrospectively analyzed from June,2009 to October,2013.The prescribed dose of planning target volume (PTV) for primary tumor was 60-66Gy (2.00-2.25 Gy,27-33 times in all).The fractional volume percent of the lung received a dose ＞5 or 20 Gy (V5,V20),and absolute volume of lung received a dose ＜5 Gy (AVS5).The mean lung dose (MLD) in normal tissues were analyzed.Regression model curve was used to analyze them along with the change of primary tumor volume.Results:With the increase in lung tumor volume,the V5,V20 and MLD presented quadratic equation curve,and AVS5 presented logarithmic equation.When the tumor volume,less than a certain value (294.6,283.2,304.9 cm3,respectively),the V5,V20 and MLD increased with tumor size and presented an increased quadratic curve;when the tumor volume was higher than a certain value (294.6,283.2,304.9 cm3 respectively),the V5,V20 and MLD was declined.The AVS5 was declined in a logarithmic curve along with the increase of tumor volume.Conclusion:With the increase in lung tumor volume,the change in rule ofV5,V20,MLD and AVS5 is not completely equivalent.When the tumor volume exceeds a certain boundary value (about 300 cubic centimeter),the corresponding tumor diameter is about 7-8 cm.In addition to the focus on pulmonary V5,V20 and MLD,we should also pay more attention to AVS5 restrictions in establishment ofIMRT in NSCLC.

Objective:To explore the regular variation pattern of tumor volumes of the patients with non-small cell lung cancer (NSCLC) before and after targeting treatment of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI),and to clarify its clinical value.Methods:The materials of 39 NSCLC patients with EGFR-TKI targeting treatment were retrospectively analyzed. The tumor volumes were detected by volume measurement software of TPS and Image J image processing software,then the absolute and relative tumor volume changes of the NSCLC patients before and after targeting treatment were analyzed by paired sample comparison symbol Wilcoxon rank test. Results:The absolute tumor volumes (mm3 )of the patients with NSCLC before and 1 month after targeting treatment were 14 822.11 (7 524.73,54 999.41)and 7 954.42 (3 499.73,29 396.83),respectively, and there was statistically significant difference (Z=-3.257,P=0.001);the absolute tumor volumes of the patients with NSCLC 1 and 2 months after targeting treatment were 8 358.47 (4 394.36,24 430.05)and 7 028.76 (3 634.98,21 056.71),respectively,and there also was statisticaliy significant difference (Z=-2.213,P=0.027).When the original tumor volume before targeting treatment was regarded as 1,the relative tumor volume of 1 month after targeting theatment was 0.612 6 (0.313 8,0.853 7),and there was significant difference (Z=-3.855,P<0.001);the relative tumor volumes of 1 month and 2 months after targeting treatment were 0.608 4 (0.364 3,1.044 3)and 0.423 0 (0.248 8,0.877 7),respectively,and there also was statistically significant differernce (Z=-2.173,P=0.030);but the differences between other consecutive months (from 3 months to 6 months)had no statistically significant differences (P>0.05);the changes of tumor relative volume presented platform stage after 3 months.The tumor relative volumes of 7-9 months after EGFR-TKI treatment reached the bottom.Conclusion:The average primary tumor volume of the NSCLC patients is obviously reduced 1 and 2 months after TKI targeting treatment. It may be optimal to carry out radiotherapy in 3-9 months after EGFR-TKI targeting treatment.

Objective To investigate the changes in ovarian function and the radiotheraputic influence on ovarian function on patients with cervical squamous cell carcinoma.Methods We retrospectively analyzed 53 cases of cervical cancer patients FIGO staging Ⅰ B1-Ⅱ B who had received ovarian transposition surgery at the Maternal and Child Health Hospital of Jiangxi province from January 2009 to June 2012.All the patients included in the study were FIGO staging Ⅰ B1-Ⅱ B and had undergone radiation therapy,including 38 staging Ⅰ B1-Ⅱ A2 cervical cancer patients receiving chemo-therapy after radical radiotherapy due to the presence of risk factors and other 15 patients with stage Ⅱ B to radical concurrent chemoradiotherapy ovarian transposition.Ovarian transposition methods would include laparoscopic ovarian transposition and transabdominal ovarian transposition.15 concurrent patients with stage Ⅱ B who currently receiving chemo-radiotherapy were under laparoscopic ovarian transposition.Among the 38 radical hysterectomy patients,31 were having abdominal ovarian transposition,and the remaining 7 cases were laparoscopic.All the 53 patients had undergone radiotherapy.The levels of serum female hormones FSH,LH,E2 were determined to monitor the ovarian endocrine function.Results According to FIGO staging,18 cases were stage Ⅰ B 1,15 cases Ⅰ B2,3 cases Ⅱ A1,2 cases Ⅱ A2 and 15 cases Ⅱ B.Patients' age range was from 28 to 44 years old,with an average of 37.7 years,median age as 38 years.14 patients (63.6％) were still normal ovarian function after radiotherapy by laparoscopic ovarian transposition,which was 100.0％before radiotherapy.There was a significant difference (P＜0.05) compared with before radiotherapy.After transabdominal ovarian transposition surgery and radiotherapy,normal ovarian function 22 cases (71.0％),and there was a significant difference (P＜0.05) compared with before radiotherapy.No significant difference was found with regard to the proportion of normal ovarian function after radiotherapy between the two groups of patients with laparoscopic and transabdominal ovarian transposition (P＞0.05).Conclusion For the young cervical cancer patients,even with ovarian transposition,ovarian dysfunction was still evident after radiotherapy.There was no significant difference between laparoscopic and transabdominal ovarian transposition.

Objective:To investigate the changes and clinical significance of serum immunoregulatory cytokines in patients with rheumatoid arthritis (RA) complicated with osteoporosis (OP).Methods:The clinical data of 420 patients with RA admitted to Mianyang Central Hospital from January 2019 to December 2019 were analyzed. According to their bone mineral density, they were divided into OP group (220 cases) and non OP group (200 cases). The immunoregulatory cytokines and bone metabolism indexes of the two groups were compared, and the correlation between them was analyzed.Results:The age, course of disease, glucocorticoid use history, fracture history, swelling joint number and tenderness joint number of OP group were significantly higher than those of non OP group ( P<0.05). In OP group, the serum levels of interleukin (IL)-6, IL-17, tumor necrosis factor-α (TNF-α) and C-terminal peptide cross-linking (CTX) of type Ⅰ collagen were significantly higher than those in control group ( P<0.05), while the IL-10 and transforming growth factor-β1 (TGF-β1) were significantly higher than that of non OP group ( P<0.05). The serum level of CTX in patients with RA complicated with OP was positively corrected with IL-6, IL-17, TNF-α ( r=0.913, 0.915, 0.921, P<0.001), and negatively correlated with IL-10 and TGF-β1 ( r=-0.921, -0.920, P<0.001). Conclusions:RA patients complicated with OP have higher age, longer course of disease, history of fracture, history of glucocorticoid use, more joint swelling and pain, higher IL-6, IL-17, TNF-α levels, lower IL-10 and TGF-β1 levels. Immunoregulatory cytokines may regulate the proliferation and differentiation of osteoclasts and osteoblasts, and play an important role in RA complicated with OP.

Objective: To evaluate the effect of tumor shape and location on pulmonary dose-volume parameters by intensity-modulated radiation therapy (IMRT) in patients with non-small cell lung cancer (NSCLC), aiming to provide a reference basis for establishing limits of the pulmonary dose-volume parameters during IMRT. Methods: Clinical data of 208 NSCLC patients undergoing radical IMRT from June 2009 to June 2016 were retrospectively analyzed. According to the tumor shape and location, 208 cases were divided into the vertical bar group (n=127) and the horizontal bar group (n=81), the superior lung group (n=103) and the inferior lung group (n=105). Regression model curve was used to evaluate the effect of tumor shape and location upon the common pulmonary dose-volume parameters(V₅, V₂₀, MLD, AVS₅ and AVS₂₀). Results: In all groups, the fitting curves of V₅, V₂₀ and MLD were manifested in the quadratic equation pattern, and AVS₅ and AVS₂₀ in the logarithmic equation manner. In the vertical bar group, the V₅(P=0.015), V₂₀(P=0.047) and MLD (P=0.012) were significantly higher, whereas the AVS₅(P=0.044) was significantly lower compared with those in the horizontal bar group. No statistical significance was observed in AVS₂₀ between two groups (P=0.490). The tumor location exerted significant effect upon V₅ alone (P=0.009). Conclusions When the tumors presents in the vertical bar shape, the limits of the common lung dose-volume parameters are likely to exceed those of tumors in the vertical bar shape. Lung tumors located in the inferior lobe exerts a more significant effect upon the low-dose region volume compared with the tumors in the superior lobe.
