Methods80 patients with stress hyperglycemia who adopted intensive insulin therapy were randomly divided into the experimental group and the control group with 40 cases in each group.The experimental group used glucose descriptive charts to record blool glucose,the control group used the traditional registration form to record blood glucose.The incidence of hypoglycemia and evaluation of medical staff for the glucose descriptive chart were compared between two groups. ResultsThe incidence of hypoglycemia in the experimental group was significantly lower than the control group.The medical staff considered that glucose descriptive chart helped understand the dynamic change of blood glucose,and provided a more comprehensive basis for regulating the use of insulin. ConclusionsApplication of glucose descriptive chart in monitoring of stress hyperglycemia can provide continuous and dynamic change of blood glucose,which facilitates the medical staff to monitor the blood glucose and decrease the incidence of hypoglycemia.

Objective: To explore apoptosis-inducing effect of lanthanum chloride in cervical cancer cells in vitro and the related mechanism, so as to provide a theoretical basis for medical use of rare earth complex. Methods: The anti-tumor activity of lanthanum chloride against HeLa cells was examined by morphological observation and MTT (3-[4, 5-dimethyrthiazol-2-yl] - 2, 5-diphenyltetrazolium bromide) assay. Distribution of cell cycle and cell apoptosis were analyzed using flow cytometry (FCM). The expression and activation of Caspass-3 were examined by Western blotting assay and spectrophotometry. Results: Morphological observation and MTT assay showed that lanthanum chloride significantly induced apoptosis in HeLa cells and inhibited cell growth in a doss-dependent manner (P<0.05). FCM analysis showed that the cell ratio of G0/G1 phase increased and that of S phase decreased significantly with the increase of lanthanum chloride doses. Lanthanum treatment also induced cell apoptosis doss-dependently. The minimum dose of lanthanum chloride to trigger apoptosis was 5 μmol/L, and the apoptosis rate increased in a doss-dependent manner compared with the control group (P<0.01). Western blotting analysis showed that lanthanum chloride up-regulated Caspass-3 expression in a doss-dependent manner. Conclusion: Lanthanum chloride can inhibit growth of human cervical cancer HeLa cells and induce cell apoptosis via Caspase pathway.

Objective: To observe the bone graft fusion of goat cervical model implanted with anterior cervical-adjustable fusion fixator(AC-AFF), laying a foundation for future studies. Methods: Eighteen experiment goats were implanted with AC-AFF, titanium mesh and autogenous iliac bone combined cervical plate after corpectomy. Six months later, the fused cervical spine vertebrae were collected, prepared, and observed grossly, under microscope, by X-ray photographs and CT scan; the fusion of the graft was evaluated. Meanwhile, the fusion of AC-AFF with the adjacent vertebral surface was observed. Results: All the experiment animals survived after operation; all the implants were stable, without displace or loosening. The interface where the titanium or AC-AFF contacts the vertebral body surface was bulged and ossified. All iliac bone graft fused well and a great deal of bony callus was found covering the vertebral body surface. Lucency area was not seen surrounding the bone graft, titanium and AC-AFF on the X-ray films, and there was new bone formation in the interface of internal fixation and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary area of implants by CT scan. And part of the new bone transited the parietal reticulation and connected with normal ossea at titanium and AC-AFF. A large number of phoroblasts and chondrocytes were found microscopically in the bone fusion sites in all cases; however, the region without bony callus still existed in the titanium mesh lateral wall. Conclusion: There are no differences in bone fusion between AC-AFF with titanium mesh and autogenous iliac bone combined cervical plate. New phoroblasts and chondrocytes can be generated in the bone graft interface. AC-AFF has been proven as an important method for cervical stability reconstruction after decompression operation.

Objective: To establish an animal model for anterior cervical-adjustable fusion fixator (AC-AFF), and to compare the operation time, blood loss, and recovery time of food intake and movement between AC-AFF group and other groups with different cervical reconstruction fixators. Methods: Eighteen goats were evenly randomized into 3 groups: AC-AFF, steel plate+ titanium mesh, and steel plate+autogenous iliac bone group. The 3 fixtors were implanted after corpectomy. The operation time, blood loss during operation, and recovery time of food intake and movement were recorded in each animal and were compared. Results: All experiment animals survived after operation; one animal of steel plate+titanium mesh group suffered from incision infection and recovered 5 days after intramuscular penicillin therapy. Two animals in steel plate+autogenous iliac bone group could not stand on forehoof, but food intake was not influenced; the animals could stand 1 week later without treatment and walked with difficulty, and they recovered normal walk 2 weeks later. Four animals received C3 corpectomy (2 received AC-AFF and 2 received steel plate+titanium mesh) and the rest received C4 corpectomy. It was found that AC-AFF group had the shortest operation time (P<0.01), and there was no difference between the other 2 groups. The intra-operation blood loss in the steel plate+autogenous iliac bone group was significantly higher than that in the other 2 groups (P<0.01), with no significant difference found between the latter 2 groups. Conclusion: AC-AFF is easier to manage than the other 2 fixators; besides, AC-AFF has less blood loss, short operation time, less post-operation complication, and early recovery of food intake and movement.

AIM: To investigate the effect and safety of laser peripheral iridoplasty combined with iridectomy in the unmanageable acute angle - closure glaucoma by medication.
METHODS:Totally 19 cases (21 eyes) with acute angle-closure glaucoma, including 15 cases ( 17 eyes ) with primary glaucoma and 4 cases (4 eyes) with intumescent cataract - induced glaucoma, were recruited into the study. The intraocular pressure ( IOP ) of all cases were still >21mmHg after 24h drug treatment, and then were treated by laser peripheral iridoplasty combined with iridectomy. The visual accurity, IOP, cornea, peripheral anterior chamber depth, anterior chamber angle and complications were observed at 24h after the surgery.
RESULTS:The mean IOP of all cases was reduced from 53. 09±11. 01mmHg before the surgery to 14. 98±4. 21mmHg at 24h after the treatment, with significant statistical difference ( P< 0. 01 ). The visual acurity of all cases increased in different degrees from handle move to 0. 3 to 0-1-1. 0 at 24h after the treatment. In all cases, cornea edema reduced or cleared up, peripheral anterior chamber depth increased, and anterior chamber angle reopened in different degrees. Complications included iris hemorrhage in 11 eyes (52. 4%), mild iritis in 21 eyes (100%). No cornea burn was encountered.
CONCLUSION: Laser peripheral iridoplasty combined with iridectomy is an effective and safe method for the treatment of the unmanageable acute angle - closure glaucoma by medication.

Objective To explore the mechanism of therapeutic action of needle knife “regulating sinews and treating bones” on knee osteoarthritis (KOA) by observing the effect of needle knife intervention on KOA rabbit behaviors, mechanical characteristics of patellar ligament (PL), and expressions of interleukin-4 (IL-4), matrix metalloproteinase-3 (MMP-3) and aggrecan in knee cartilages.Methods Forty New Zealand rabbits were randomly allocated to blank, model, needle knife and electroacupuncture groups, 10 rabbits each. A rabbit model of KOA was made by the modified Videman method of immobilization in extension position. After model making, the needle knife and electroacupuncture groups received needle knife and electroacupuncture treatments, respectively. A behavioral assessment was made using the modified Lequesne MG knee grade evaluation method in every group after model making and treatment. The samples were taken after treatment. PL tension, stress relaxation and creep state were tested using a Bose Electro Force 3300 protracted test machine. Cartilage cell IL-4 expression was examined by ELISA. MMP-3 mRNA and aggrecan mRNA expressions were detected by real-time PCR.Results After model making, there was a statistically significant difference in the Lequesne MG score between the model and blank groups (P<0.01); there was no statistically significant difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P>0.05). There was a statistically significant post-treatment difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P<0.01,P<0.05) and between the needle knife and electroacupuncture groups (P<0.05). There were statistically significant post-treatment differences in PL maximum stress, maximum displacement, elastic modulus, stress relaxation rate and creep rate between the model and blank groups (P<0.01,P<0.05). There were statistically significant post-treatment post-treatment differences in PL maximum stress, maximum displacement, elastic modulus, stress relaxation rate and creep rate between the needle knife and model groups (P<0.01,P<0.05). There was a statistically significant post-treatment difference in elastic modulus between the electroacupuncture and model groups (P<0.01). The IL-4 content and aggrecan mRNA expression decreased significantly and MMP-3 mRNA expression increased significantly in the model group after model making and there were statistically significant differences compared with the blank group (P<0.01,P<0.05). After treatment, the IL-4 content increased significantly in the needle knife and electroacupuncture groups compared with the model group (P<0.01,P<0.05) and aggrecan mRNA expression tended to increase in the two groups. The regulation of aggrecan mRNA and MMP-3 mRNA expressions was better in the needle knife group than in the electroacupuncture groups, but there was no statistically significant difference compared with the model group (P>0.05).Conclusion The mechanism of action of needle knife treatment on KOA may be that it improves ligament mechanical characteristics, regulates intra-articular stress environment, and modulates aggrecan mRNA and MMP-3 mRNA expressions and inhibits cartilage degeneration through IL-4 mechanical signal pathway, to produce the therapeutic effect of “regulating sinews and treating bones”.

The capsule endoscope swallowed from the mouth into the digestive system can capture the images of important gastrointestinal tract regions. It can compensate for the blind spot of traditional endoscopic techniques. It enables inspection of the digestive system without discomfort or need for sedation. However, currently available clinical capsule endoscope has some limitations such as the diagnostic information being not able to correspond to the orientation in the body, since the doctor is unable to control the capsule motion and orientation. To solve the problem, it is significant to track the position and orientation of the capsule in the human body. This study presents an AC excitation wireless tracking method in the capsule endoscope, and the sensor embedded in the capsule can measure the magnetic field generated by excitation coil. And then the position and orientation of the capsule can be obtained by solving a magnetic field inverse problem. Since the magnetic field decays with distance dramatically, the dynamic range of the received signal spans three orders of magnitude, we designed an adjustable alternating magnetic field generating device. The device can adjust the strength of the alternating magnetic field automatically through the feedback signal from the sensor. The prototype experiment showed that the adjustable magnetic field generating device was feasible. It could realize the automatic adjustment of the magnetic field strength successfully, and improve the tracking accuracy.
