Objective To characterize the biomechanical behavior and properties of the chondrons enzymatically isolated from rabbit knee articular cartilage in virto. Methods Eight months old New Zealand white rabbits were randomly divided into chondroctye and chondron groups (4 rabbits in each group). In chondrocyte groups, the full articular cartilages from both knees were enzymatically isolated to chondrocytes by 0.4% pronase and 0.025% collagenase type-Ⅱ in turn. In chondron groups, chondrons were obtained from articular cartilage using the mixture of 0.3% dispase (a neutral protease) and 0.2% collagenase type-Ⅱin at 37C for 3 h. The micropipette aspiration was used to quantify changes in biomechanical properties of chondrons and chondrocytes and the viscoelastic parameters, including K1, K2, E∞ (equilibrium modulus), E0(instantaneous modulus), and μ (apparent viscosity), were calculated coupled with standard linear half-space viscoelastic solid model. Results In response to a constant negative pressure of 0.2-0.4 kPa, the chondrocytes exhibited standard linear viscoelastic solid properties. Namely, the cells showed an initial elastic response followed by a viscoelastic creep response. then cells continued to enter into the micropipette with a monotonically decreasing rate of deformation, until reaching equilibrium within about (110±18) s. Comparing with chondrocytes, the chondrons exhibited significant viscoelasticity under a greater negative pressure of 1.0-1.2 kPa. But the instantaneous length deformed into the micropipette significantly reduced, and the equilibrium time reduced to (36.5±4.5) s. The equilibrium modulus (E∞), the instantaneous modulus (E0) and the apparent viscosity (μ) of chondrons were significantly higher than the those of chondrocytes. Conclusion Comparing with chondrocytes, the chondrons exhibited significant viscoelastic properties, and viscoelastic properties of chondrons have increased in vitro.

Objective To investigate the changes in cerebral hemodynamics in different body positions in healthy volunteers.Methods Sixty right-handed healthy male volunteers,aged 22-26,height 167-178 cm,weighing 51-67 kg,were randomly divided into 4 groups ( n =15 each): 15 degrees head-down tilt group (group Ⅰ ),30 degrees head-down tilt group (group Ⅱ ),15 degrees head-up tilt group (group Ⅲ) and 30 degrees head-up tilt group (group Ⅳ ).Blood flow signals of right middle cerebral artery (MCA) and extracranial internal carotid artery (EICA) were detected by transcranial Doppler and systolic blood flow velocity (Vs),diastolic blood flow velocity (Vd ),mean blood flow velocity (Vm),pulsatility index (PI) and resistance index (RI) were recorded at supine position (baseline),immediately,10 and 30 min after body position change(T1-3 ).Lindegaard index was calculated.Results Compared with the baseline,in group [Ⅱ Lindegaard index was increased at T2,while Vs and Vm of MCA were decreased at T2,3,in group Ⅳ Vs of MCA and PI of EICA at T2,Vd and Vm of MCA at T2,3 were decreased ( P ＜ 0.05),while there was no significant difference in the variables mentioned above in the other two groups ( P ＞ 0.05 ).Conclusion In healthy adults,cerebral blood flow velocity decreases in 30 degrees headdown and head-up tilt positions,however there is no change in cerebral blood flow velocity in 15 degrees headdown and head-up tilt positions.

Objective To explore the short term treatment effectiveness and the side-effect of radiotherapy combined with two kinds of chemotherapy scheme on nasopharyngeal carcinoma patients with stage Ⅲ and Ⅳa.Methods One hundred and fifty nasopharyngeal carcinoma cases with stage Ⅲ/Ⅳa were randomly divided into A and B group.Patients in A group (75 cases) were received radiotherapy combined with 2 courses ((21-28) d/course) paclitaxel (135 mg/m2) + cis-platinum complexes (DDP) 80 mg/m2 chemotherapy concurrently,while patients in B group (75 cases) were received radiotherapy combined with 6 courses DDP 30 mg/m2 per week chemotherapy concurently.The short term treatment effectiveness and the sideeffect of radiotherapy combined with two kinds of chemotherapy scheme were observed.Result After the treatment,the primary lesion complete remission(CR) rate in A group and B group were 68％ (51/75),52％ (39/75).The CR rate of lymph node of neck in A and B group was 64.0％ (48/75),48.0％ (36/75) and 45.3％ (34/75),20.0％ (15/75) of primary lesion and lymph node of neck.The differences were significant(x2=4.25,3.90,10.94 ;P ＜0.05).After 3 months of treatment,there was no significant difference between A and B group in terms of CR rate of the primary lesion,lymph node of neck and primary lesion and lymph node of neck (P ＞0.05).During the treatment,the rate of bone marrow depression at grade Ⅲ in A group and B group were 38.67％ (29/75) and 21.33％ (16/75),21.33％ (16/75) and 6.67％ (5/75) in terms of the rate of grade gastrointestinal reaction at stage Ⅲ,46.66％ (35/75) and 21.33％ (16/75) regarding of oral cavity mucomembranous injury at stage Ⅲ,21.33％ (16/75) and 9.34％ (7/75) in terms of the rate of radioactivity skin destruction at stage Ⅲ.All differences were significant (P ＜ 0.05).During the short-term follow up (1-3 years),both the rate of local recurrence and the rate of metastasis in A group was as same as that in B group(P ＞0.05).Conclusion During the treatment,the side-effect of approach of paclitaxel (135 mg/m2) + DDP 80 mg/m2 in stage Ⅲ/Ⅳa nasopharyngeal carcinoma patients is more severity than that of DDP 30 mg/m2 per week chemotherapy.However,there is no significant difference in terms of the short term treatment effectiveness.The prospective efficacy needs to be further investigation.

Objective:To explore the effect of Dachengqi Decoction and enteral nutrition on the recovery of gastrointestinal function in patients with gastric cancer.Methods:From September 2018 to September 2019, 100 patients with gastric cancer undergoing radical gastrectomy in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine were selected as the research objects, and were divided into observation group and control group according to the random number table method, each group contained 50 cases. Among them, the control group was given routine diet before operation to provide pre adaptation of enteral nutrient solution; the observation group was added with Dachengqi Decoction on the basis of routine diet. The recovery of gastrointestinal function, plasma motilin (MTL), serum gastrin (GAS) and gastrointestinal complications were observed and compared between the two groups.Results:There were 3 cases of abdominal distention and diarrhea in the control group, 1 case of diarrhea and 1 case of nausea and vomiting in the control group. The total incidence of gastrointestinal complications was 16% (8/50). There was 1 case of abdominal distention and 1 case of diarrhea in the observation group, and the total incidence of gastrointestinal complications was 4%(2/50). The difference between the two groups was statistically significant ( χ2 value was 4.000, P<0.05). In the observation group, the time of first bowel sounds, exhaust time and defecation time were (26.12 ± 5.32) h, (25.49 ± 4.49) h, (32.63 ± 4.31) h, respectively, which were significantly shorter than those in the control group (32.24 ± 6.41) h, (46.74 ± 6.14) h, (49.51 ± 6.28) h, and the difference was statistically significant ( t value was 5.195, 19.754, 15.671, P<0.05). The plasma MTL and serum gas in the observation group were (346.54 ± 18.58) ng/L, (123.44 ± 6.19) ng/L. After operation, the results were (247.24 ± 11.40) ng/L, (85.46 ± 5.12) ng/L. The difference was statistically significant ( t value was 97.793, 250.990, P<0.05). The plasma MTL and serum gas of the control group before operation were (344.63±16.65) ng/L and (122.53 ± 6.35) ng/L respectively. After operation, the results were (205.84±10.21)ng/L, (64.79±5.24) ng/L. The difference was statistically significant ( t value was 152.390, 367.823, P<0.05). The levels of plasma MTL and serum gas in the observation group were significantly higher than those in the control group ( t value was 19.129, 19.95, P<0.05). Conclusions:The modified Dachengqi Decoction and the pre adaptation of enteral nutrition solution are helpful to reduce the occurrence of various gastrointestinal complications after gastric cancer operation and promote the rapid recovery of gastrointestinal function, which may be related to the promotion of the secretion of MTL and gas.

Objective:To analyze the epidemiological features of geriatric humeral surgical neck fractures from 2010 through 2019 in The Third Hospital of Hebei Medical University.Methods:A retrospective study was conducted of the data of the inpatients aged ≥60 years who had been treated for humeral surgical neck fractures in The Third Hospital of Hebei Medical University from 2010 through 2019. The patients were divided into 2 groups by the year of admission: the former five-year group (group A from January 1, 2010 to December 31, 2014) and latter five-year group (group B from January 1, 2015 to December 31, 2019). The data of the patients were compared between the 2 groups to find the epidemiological characteristics and trends of the humeral surgical neck fractures in the 10-year period.Results:A total of 312 geriatric humeral surgical neck fractures were included, accounting for 1.2%(312/25, 764) of the upper limb fractures and 0.4% (312/88, 886) of all the fractures in the same period. There were 64 males and 248 females, giving a male/female ratio of 0.26∶1. Their ages ranged from 60 to 93 years. The peak age of the fractures was from 60 to 69 years for both males and females. Falls and indoor activity injuries accounted for the largest proportion (71.2%, 222/312). The common fracture types were 11-A2 and 11-A3. The proportion of overweight and obese patients by the body mass index (BMI) was the largest (58.7%, 183/312). There were no statistically significant differences between groups A and B in male/female ratio (0.37:1 versus 0.22:1) or in proportion of peak age patients [42.7% (38/89) versus 55.2% (123/223)] ( P>0.05). There were statistically significant differences between the 2 groups in injury causes, fracture types and BMI distribution ( P<0.05). Conclusions:The geriatric humeral surgical neck fractures accounted for 1.2% of the upper limb fractures and 0.4% of all the fractures in the same period. There were more female patients than male ones. Falls and indoor activity injuries were the most common causes. The proportions of complex fractures and overweight and obese patients increased.

OBJECTIVETo evaluate the correlation of p27 protein expression in the cytoplasm with the clinicopathologic features of nasopharyngeal carcinoma (NPC).

METHODSImmunohistochemistry was employed to examine P27 protein expression in the cytoplasm of NPC samples and nasopharyngeal (NP) tissue samples. The differential expression of P27 protein between NPCs and NPs and the correlation of cytoplasmic P27 protein expression with the clinicopathologic parameters of NPC patients was analyzed. RESULTS Immunohistochemistry indicated significantly down-regulated t p27 protein expression in NPC tissues compared to that in NP tissues (P=0.047). The reduction of P27 expression was inversely correlated with T classification of NPC (P=0.033). Although cytoplasmic p27 protein expression was not significantly correlated with lymph node metastasis (P=0.157) or clinical stages of NPC (P=0.090), an obvious trend of inverse correlations between them was noted.

CONCLUSIONDown-regulated cytoplasmic p27 protein expression may promote the carcinogenesis of NPC and can be an unfavorable prognostic factor for survival of NPC patients.
