Objective To investigate the cut-off point value of 1-hour plasma glucose of oral glucose tolerance test in the diagnosis of the T2DM and IGR.Methods Three hundred and fifty-four subjects (6.0mmol/L≤ FPG ＜ 7.0mmol/L) were participated in the OGTT.To get the cut-off point value of 1-hour plasma glucose in the diagnosis of the T2DM and IGR by applying the receiver operator characteristic curve,and compare it with the WHO diagnostic criteria.Results (1)The cut-off point value of screening T2DM by ROC curve was 12.90mmol / L,whose specificity was 77.1％ and sensitivity was 90％.Meanwhile the cut-off point value of screening IGR was 10.83mmol / L,whose specificity was 73.2％,and the sensitivity was 73.5％.(2)Among the 136 patients with type 2 diabetes mellitus that diagnosed by WHO criteria,115 patients could be diagnosed by 1hPG that more than FPG which could diagnose 81 patients.And the difference was statistically significant (P ＜ 0.05).Meanwhile,It was more than 106 patients that diagnosed by 2hPG,but there was no statistically significant.According to the diagnostic criteria of 2hPG ≥11.1mmol/L,there were 106 cases of T2DM.Among these patients,95 cases and 51 cases could be diagnosed respectively by 1 hPG and FPG,and there was statistically significant (P ＜ 0.01).(3)Application of the cut-off point of 1 hPG,NGT,IFG,CGI and DM re-grouped.FPG,2hPG increased gradually in order to NGT,IGR,DM.(4) No matter the blood glucose levels,1hPG and 2hPG had good correlation,(P =0.000).A significant correlation could be found between FPG and 2hPG only in hyperglycemia.The correlations between 1 hPG and FPG disappeared only in a normal level of blood glucose.Conclusion The cutoff point value of 1hPG is 12.90mmol/L which has advantage to diagnosis of type 2 diabetes mellitus.It is a useful complement to the WHO Diagnostic criteria.

Objective:To compare the volatile constituents in mugwort leaves produced in Qichun, Hubei Province and Nanyang, Henan Province.
Methods:The volatile constituents were extracted using headspace heating and analyzed using gas chromatography-mass spectrometry (GC-MS). Then a qualitative analysis was made according to the standard database provided by the National Institute of Standards and Technology (NIST) and the relative contents of each constituent were calculated using the peak area normalization method.
Results:A total of 59 compounds were identified from the mugwort leaves from Qichun and 51 compounds were identified from the mugwort leaves from Nanyang. These mainly include monoterpenoids, sesquiterpenoids, CxHyOz and other compounds involving the aldehyde, ketone, alkane and benzene. The mugwort leaves from Qichun and Nanyang share 32 common volatile constituents. The chromatographic peak area of identified compounds accounting for 96.38% of GC-MS total chromatographic peak areain Qichun mugwort leaves, versus 95.54% of that in Nanyang mugwort leaves.
Conclusion:The headspace heating extraction combined with GC-MS technology can evidently display similarities and differences of volatile constituents in mugwort leaves produced in different areas and thus provide scientific basis for the quality and screening of mugwort leaves.

Objective To verify the clinical effect of Qinghuang powder in chronic myelogenous leukemia(CML). Methods 86 CML patients treated with Qinghuang powder, in which 28 cases also partially received herbal medicine (activating blood circulation to dissipate blood stasis). Results 62 cases had complete remission (72.1%), 14 cases partial remission (16.3 %), advance 8 cases(9.3 %), inefficiency 2 cases (2.3 %), and the total efficiency was 97.7 %. The symptom were improved after a week when patients had taken medicines. 44 cases have hepatomegalia, among them 39 cases have diminished or became normal compared to untreated. 70 cases have splenoparectasis, among them 60 cases became normal, 9 cases diminished, and 1 case had no change after treatment. It took 15.5 days in average when spleen began to diminish, and took 62.9 days to become smallest. The WBC began to decrease at 10.4 day and took 54.8 days in average became normal. The major side effect was digestive tract symptom, followed by skin pigmentation and skin excessive cornification. It could be avoided by low dosage. Conclusion Qinghuang powder could not only induce CML to CR, but also improve the clinical symptom of CML and eliminate the infiltration of leukemia cells. It has little influence to Hb and Plt.

Objective:To explore the effects of micro-classroom on pulmonary function, compliance with inhaled glucocorticoids, self-management ability and quality of life in children with bronchial asthma at school age.Methods:A total of 116 children with school-age bronchial asthma who were treated in our hospital from January 2018 to January 2019 were selected. Children were divided into control group ( n = 58) and observation group ( n = 58) according to the method of random numbers. The children in the control group were given routine health education, and the children in the observation group used micro-class health education strategies based on the control group. Intervention time was 3 months. The lung function indexes, inhaled glucocorticoid compliance, self-management ability, and quality of life were compared between the two groups before and after the intervention. Results:After the intervention, the forced vital capacity (FVC), forced expiratory volume percentage (FEV1%), peak expiratory flow rate (PEF), and forced expiratory 25% vital capacity instantaneous flow rate (FEF25%) were increased in both groups. The observation group was (6.29 ± 0.75) L, (75.61 ± 10.59)%, (91.55 ± 12.82) L / s, and (83.45 ± 10.85) L / s. All were higher than (5.98 ± 0.66) L, (71.25 ± 7.84)%, (78.92 ± 11.8) L / s, and (59.91 ± 8.39) L / s in the control group, and the differences were statistically significant ( t value was from -13.071 to -2.363, P <0.05 or 0.01). The Morisky-Green score of the control group decreased after the intervention ( t value was 7.937, P <0.05). The Morisky-Green score of the observation group showed no significant change compared with that before the intervention ( t value was 0.883, P> 0.05). The scores of self-care ability, nursing skills, sense of responsibility, self-concept, and health knowledge on the self-care ability scale of the observation group after the intervention were (21.05 ± 2.53), (17.53 ± 2.63), (17.65 ± 1.94), (27.35 ± 4.10), (27.36 ± 4.10) minutes. All were higher than the (15.68 ± 2.20), (13.58 ± 1.49), (14.56 ± 1.75), (20.45 ± 2.86), (22.35 ± 2.68) points of the control group, and the difference was statistically significant ( t value was from -12.198 to -7.790, P <0.01). In the observation group after intervention, the quality of life scale, asthma symptoms, mental state, response to stimulus, and health care scores were (75.68 ± 9.08), (58.91 ± 8.25), and (46.98 ± 7.05), (38.51 ± 5.39), (28.95 ± 4.05) minutes. All were higher than (68.35 ± 8.89), (51.23 ± 7.68), (41.05 ± 6.16), (31.58 ± 3.79), (22.36 ± 2.68) points in the control group, and the difference was statistically significant ( t value was from -10.334 to -4.393, P <0.01). Conclusion:The micro-classroom intervention mode for school-age children with bronchial asthma can effectively maintain treatment compliance, help improve children's lung function indicators, and improve children's self-management ability and quality of life.

OBJECTIVETo study the antiinflammatory effects of naphtha from different chemotypes of Cinnamomum camphora and natural borneol on the rat arthritis model induced by Freund's adjuvant.

METHODThe arthritis model was induced by injecting Freund's adjuvant in rat voix pedis dermis and the rats were randomly divided into seven groups: normal control group, model control group, triptergium wilfordii control group, borneol chemotype naphtha group, camphor chemotype naphtha group, isocamphane chemotype naphtha group and natural borneol group. Rats of the triptergium wilfordii control group were given orally 8.1 mg x kg(-1) triptergium wilfordii for 35 days, rats of the normal control group and model control group were given same volume water, and rats of other groups were given 80 mg x kg(-1) corresponding drug. We observed the rat common condition, weighed the rat body weight weekly, measured the degree of swelling of voix pedis every 4 days, weighed the thymus and spleen on the end of life, and measured the contents of cell factor TNF-alpha, IL-2, and IL-6 in rat blood serum.

RESULTAs far as the arthrosis degree of swelling and the contents of cell factor TNF-alpha, IL-2, IL-6 were concerned, rats of model control group were higher than normal control group, and rats of other drug groups were lower than the model control group. The order of inhibition ratios of the arthrosis degree of swelling from high to low principle was isocamphane chemotype naphtha group, camphor chemotype naphtha group, borneol chemotype naphtha group and natural borneol group. All medication administration teams evidently reduced the contents of the IL-2 and IL-6, and the inhibition ratios were higher than 38%. In the case of the contents of TNF-alpha and IL-2, all groups were not evidently different. In the case of inhibition of IL-6, camphor chemotype naphtha group was better than borneol chemotype naphtha group and natural borneol group, the latter was better than isocamphane chemotype naphtha group. As far as the weight, thymus index and spleen index were concerned, all medication administration groups were not different.

CONCLUSIONThe different chemotypes of C. camphora have anti-inflammatory effect on the rat arthritis model induced by Freund's adjuvant, but pharmacological activity and mechanism of action are different. The study points out the clinical curative effects of the chemotypes of the kindred medicinal plant are different, and please consider the difference of chemotype in clinical application.

Objective:To evaluate our novel path based on anatomical division of the anterior lateral wall of calcaneus and the sustentaculum tali for precise sustentacular screw placement in the surgical treatment of calcaneal fractures of Sanders types Ⅱ and Ⅲ.Methods:The anterior lateral wall of the calcaneus was divided into the anterior-superior zone S 1, the anterior-inferior zone S 2, the posterior-superior zone S 3 and the posterior-inferior zone S 4 for demarcation of the screw insertion points by our method of Four Zones, and into the front, middle and rear sections by our method of Three Sections for demarcation of the screw target points. The specimens were scanned by CT and modeled by Mimics. On the 3D virtual model of the calcaneus, one screw was placed from each zone of the anterior lateral wall of the calcaneus to the sustentaculum tali body. The screw placement target for S 1 and S 2 was the medial intersection point P 1 of the front and middle sections of the sustentaculum tali, and that for S 3 and S 4 was the medial intersection point P 2 of the middle and rear sections of the sustentaculum tali. It was observed whether the screws were placed in the bone channel. A total of 72 patients were included who had been admitted to Department of Orthopaedics, Suqian Hospital Affiliated to Xuzhou Medical University for calcaneal fractures of Sanders types Ⅱ and Ⅲ from January 2017 to January 2021. They were divided into an anatomical division group and a 3D printing group according to their screw placement method for the sustentaculum tali. In the anatomical division group of 32 patients subjected to screw placement based on our anatomical division, there were 25 males and 7 females, aged from 24 to 60 years; in the 3D printing group of 40 patients subjected to screw placement assisted by 3D printing, there were 31 males and 9 females, aged from 25 to 58 years. The disparities between the parameters of sustentacular screw placement and the actual values were compared in the anatomical division group, and the total number of screws, screws on average, distribution of screws, and accuracy of screw placement were compared between the 2 groups. Results:All the screws which were virtually placed in the specimens of the calcaneus from S 1 and S 2 to P 1 and from S 3 and S 4 to P 2 passed through the bony channel, with no perforation into the tarsal sinus. There was no significant difference in the general date between the anatomical division group and the 3D printing group, showing they were comparable ( P > 0.05). In the anatomical division group, a total of 52 screws were placed to the sustentaculum tali with an average of (1.63 ± 0.48) screws per patient, and 2 screws were placed in 20 patients, yielding an accuracy rate of screw placement of 92.3% (48/52). There were no statistically significant differences between the parameters and the actual values of screw placement in the anatomical division group ( P > 0.05). In the 3D printing group, a total of 63 screws were placed to the sustentaculum tali with an average of (1.58 ± 0.49) screws per patient, and 2 screws were placed in 23 patients, yielding an accuracy rate of screw placement of 93.7% (59/63). There were no significant differences in the above comparisons between the anatomical division group and the 3D printing group ( P > 0.05). Conclusion:In the surgical treatment of calcaneal fractures of Sanders types Ⅱ and Ⅲ, the sustentacular screw placement based on our anatomical division of the anterior lateral wall of the calcaneus and the sustentaculum tali can lead to similar clinical accuracy as 3D printing-assisted screw placement does.
