Objective To investigate the change of immunologic function of red blood cell (RBC) in patients with chronic gastritis. Methods The immunologic function of RBC in 88 cases of chronic gastritis was dynamically detected with yeast rosette method. Results The results showed that RBC-C3b receptor rosette (RBC-C3b-RR) rate and RBC immune adherence enhance factor (RFER) rate were significantly lower (P＜0.05) and RBC immune complex rosette (RBC-ICR) rate and RBC immune adherence inhibitor factor (RFIR) were significantly higher (P＜0.05) in the patients with atrophic gastritis than those in control group. In the patients with superficial gastritis, the difference had no distinct significance (P＞0.05). Conclusion The immunologic function of red blood cell (RBC)measurement plays an important role in differential diagnosis and prognosis evaluation of chronic gastritis.

Objective To investigate the effect of medial collateral ligament reconstruction using semitendinosus autograft.Methods A total of 12 patients with medial collateral ligament injury received knee examinations.Among them,2 had lateral meniscus injury,and received partial resection of the lateral meniscus;2 had cruciate ligament(CL) injury(anterior CL in one and posterior CL in the other),and underwent bone-ligament-bone reconstruction.Medial collateral ligament reconstruction was performed using the semitendinosus tendon autograft ingrowth in the tibial tunnel.Results Primary healing was achieved in all the cases.In 10 of them,the stability of the knee was regained in 6-month follow-up;stress X-ray examination showed that the medial joint space was smaller than the contralateral one by less than 5 mm,and the position of the interference screw was optimal.Of the 12 patients,11 achieved an active knee flexion between 0? and 120?,the other,who had fracture of the lateral condyle of the femur,had a flexion of 90?.Conclusions Semitendinosus autograft provides sufficient tension for medial collateral ligament reconstruction.The fixation of the knee and the closure of the joint capsule can be achieved by using the method.

Objective To study the expression of hemeoxygenase-1 (HO-1) and change of superoxide dismutase (SOD) activity in perihematoma after intracerebral hemorrhage (ICH). Methods The rats were randomly divided into sham operating group and intracerebral hemorrhage group.Rat ICH models were induced using stereotactic infusion autologous blood 50 ?l into the caudate nucleus. At the due time, the rats were killed and brain tissues were removed for detection of HO-1 and measurement of SOD by immunohistochemical and xanthine hydrocarbonylation methods. Results Following ICH, few HO-1 positive cells were observed in brain tissue perihemota at 6 h, peaked at 48 h ( P0.05), then decreased gradually and reached the minimum at 72 h ( P0.05). The change of SOD in brain tissue perihematoma was negatively correlated with the expression of HO-1 (r=-0.878, P

Objective Previous studies have found that micheliolide(MCL) could improve the sensitivity of breast cancer cells to chemotherapeutic drugs such as cisplatin and induce the apoptosis of breast cancer cells.This article aims to study the proliferation inhibition effect of micheliolide on lung cancer cells H460 and its underlying mechanism.Methods Human lung cancer cell line H460 was treated with different concentrations of micheliolide(30,60,90μmol/L).Then the cell proliferation was measured by-CCK8 and plate colony formation assays.The apoptosis and the cell cycle were detected by flow cytometry.Western blot was used to determine the mechanism of how MCL affecting cancer cell H460.Results Compared with the control (275.00±7.21), the clone numbers after 30μmol/L,60μmol/L and 90μmol/L MCL treatment(199.00±5.66,166.00±1.41, 90.00±7.81) were significantly decreased (P<0.05).Meanwhile, the CCK-8 results showed that compared to the control group, A value was significantly increased after 30μmol/L MCL treatment for 72h and 96h, and 60μmol/L or 90μmol/L MCL treatment for 48h,72h and 96 h (P<0.05).Compared with the control apoptotic ratio [(2.90±0.03)％], the ratio of early and late apoptotic cells after 30μmol/L, 60μmol/L and 90μmol/L MCL treatment [(5.23±0.76)％, (9.06±0.47)％, (19.00±0.64)％] were significantly increased (P<0.05).Compared with the control group, the ratio of G2/M phase cells[(12.52±0.88) ％ ,(17.22±0.43)％, (19.84±0.31)％] was gradually increased after 30μmol/L, 60μmol/L and 90μmol/L MCL treatment, and there was statistically significant difference after 60μmol/L and 90μmol/L MCL treatment (P<0.05).The ratio of S+G1/G0 phase cells[(87.53±1.06)％ ,(82.94±0.67)％ ,(79.79±0.21)％] was gradually decreased after 30μmol/L, 60μmol/L and 90μmol/L MCL treatment, and there was statistically significant difference after 60μmol/L and 90μmol/L MCL treatment (P<0.05).The expression level of notch4 was significantly decreased after 30μmol/L, 60μmol/L and 90μmol/L MCL treatment (P<0.05), while the expression level of cleaved caspase3 was significantly upregulated (P<0.05).Conclusion MCL exerted an inhibitory effect on lung cancer cell H460.

Inflammatory bowel disease( IBD)is a group of chronic nonspecific intestinal diseases characterized by a clinical relapsing-remitting behavior. The evaluation of disease activity is concerned by clinicians all the time. With the evolving in recognition of the pathogenesis of IBD,many novel biomarkers are emerging in recent years. This article reviewed advances in the accepted and ongoing research fecal markers of IBD.

Objective To explore the feasibility of nasolabial fold wrapped perforator flap in repairing pinna defects to produce the relative perfect appearance.Methods We treated 10 cases of pinna nasi defects by the nasolabial fold wrapped perforator flap.We examined the blood vessel distribution and exit of the blood vessel before surgery,and designed the nasolabial fold wrapped perforator flap according to the pinna defects.The flap with reasonable thickness was able to repair the both sides of defect after being cut properly.Meanwhile,the flap could be folded to form a local flap covered or lined with skin,and rotately transfered to repair nasal alar defect.Results All the flaps survived with incisions of donor sites healed primarily.Following up for 4 to 24 months showed that the color,texture and thickness of the flaps were similar to those of recipient sites.The scar in donor site was concealed and not obvious.Those cases who kept neurocutaneous branch had good sense.Satisfactory appearance was received without secondary repair.Conclusions The nasolabial fold wrapped perforator flap has abundant blood circulation and easily survives.It can also afford ample tissues to repair major area of pinna nasi defects,The blood vessel peduncle is too long to be survived easily.And the donor has not clear scar.Second reconstruction can be avoided in this procedure.The nasolabial fold wrapped perforator flap is one of the best choices to repair pinna defects.
