Objective:To explore the effect of different doses of lidocaine on recovery quality of patients with iodine-deficiency goiter after general anesthesia resection.Methods:Using a prospective design, 108 patients who underwent iodine-deficiency goiter resection in Yantai Yeda Hospital from April 2018 to April 2020 were selected as the research subjects. The patients were divided into control group (normal saline), lidocaine group A (1 mg/kg) and lidocaine group B (2 mg/kg) by random number table method, 36 cases in each group. The corresponding dose of lidocaine or the equivalent dose of normal saline was pumped into the vein after anesthesia induction and intubation for 30 minutes. The changes in the diastolic blood pressure (DBP), systolic blood pressure (SBP) and blood glucose (GLU) levels of the three groups were observed before administration, immediately after the operation, immediately after opening the eyes, immediately after extubation, and 10 minutes after extubation; at the same time, arousal and restlessness score (RS), sedation score (Ramsay), visual analogue score (VAS) and adverse reactions(coughing, nausea and vomiting, respiratory depression) occurrence were recorded.Results:At the moment of eye opening, immediately after extubation and 10 minutes after extubation, DBP (mmHg: 77.26 ± 4.85, 73.45 ± 4.37, 70.94 ± 4.45, 83.53 ± 6.19, 77.86 ± 5.33, 74.14 ± 5.20, 73.86 ± 5.73, 68.41 ± 5.16, 63.09 ± 5.24), SBP (mmHg: 129.17 ± 6.54, 121.25 ± 6.07, 116.24 ± 5.86, 137.48 ± 6.62, 129.53 ± 6.38, 123.07 ± 6.25, 125.65 ± 6.13, 117.48 ± 6.09, 108.17 ± 6.04), GLU level (mmol/L: 5.83 ± 0.36, 5.37 ± 0.29, 5.12 ± 0.26, 6.69 ± 0.34, 5.84 ± 0.30, 5.57 ± 0.27, 5.61 ± 0.32, 5.25 ± 0.31, 4.97 ± 0.28) of lidocaine group A and lidocaine group B were significantly lower than those of control group, the difference were statistically significant ( F=17.520, 25.755, 36.034, 41.028, 45.525, 74.330, 10.397, 49.756, 52.348, P < 0.05); among them, the DBP, SBP and GLU levels of lidocaine group A and lidocaine group B were lower than those of control group, and lidocaine group B was lower than lidocaine group A ( P < 0.05). The RS and VAS of lidocaine group A and lidocaine group B were significantly lower than those of control group, and Ramsay was higher than that of control group ( P < 0.05); and the RS and VAS of lidocaine group B were lower than those of lidocaine group A, the Ramsay was higher than that of lidocaine group A ( P < 0.05). The incidence of coughing, nausea and vomiting in lidocaine group A and lidocaine group B were lower than those in the control group ( P < 0.05); and there was no respiratory depression in the three groups. Conclusions:Thrity minutes after induction of anesthesia, continuous pumping of 2 mg/kg lidocaine can maintain blood pressure and GLU of patients undergoing general anesthesia for iodine-deficiency goiter, and effectively reduce restlessness, pain and adverse reactions during the recovery period. It is a satisfactory dose for thyroid surgery patients to wake up and comfortably.

OBJECTIVETo investigate the clinical experiment of cortical screw in the treatment of tibiofibular syndesmosis separation together with ankle fractures.

METHODSFrom March 2008 to May 2012,42 patients with tibiofibular syndesmosis separation were treated with cortical screw, including 20 cases in the left and 24 cases in the right. All the patients had closed injury. According to Lauge-Hansen classification, there were 18 cases of supination-external rotation, in which 4 patients with injuries belong to type II, 8 patients with injuries belong to type III, 6 patients with injuries belong to type IV; 14 cases of pronation-external rotation, in which 6 patients with injuries belong to type III, 8 patients with injuries belong to type IV; and 12 cases of pronation-abduction, in which 4 patients with injuries belong to type II, 8 patients with injuries belong to type III. According to injury of ankle, 4 patients had injuries in one ankle, 28 patients had injuries in 2 ankles, and 12 patients had injuries in 3 ankles. All the patients were diagnosised definitely in sight of medical history, checking-up, iconography. The clinical effects were evaluated based on Baird-Jackson score and activity degree of ankle.

RESULTSAll the patient were followed up, and the duration ranged from 11 to 23 months, with an average of 15.7 months. No postoperative wound infection, nonunion, and tibiofibular syndesmosis separation again and other complications occurred. Postoperative Baird-Jackson score exhibited 91.56 ± 6.26 (75 to 99), and 26 patients got an excellent result, 10 good, 6 poor and 2 bad. One patient had nail broken after operation,and got good function after removing broken nail without external fixation. Other 1 patient had osteoarthritis to 1 degree, and got better result with the treatment of physical therapy and intra-articular injection.

CONCLUSIONCortex screw is the effective treatment for tibiofibular syndesmosis separation. Clear diagnosis, delicate operation and postoperative reasonable functional exercise are primary factor of prognosis.

Objective To investigate the prevalence of serum Anti-sperm antibodies(AsAb) in group of prepubertal boys with cryptor-chidism before and after surgery,and explore whether it may be influenced by testicular location,orchiopexy,unilateral or bilateral cryptorchi-dism and deferens and(or) epididymis abnormality.Methods Serum AsAb was examined in 50 prepubertal boys with cryptorchidism and 50 boys with oblique inguinal hernia before and 6 months after surgery.Fifty boys who were normal were served as controls.IgG and IgM AsAb were determined by the immunodotting method.Results The preoperative and post-orchiopexy serum AsAb positive rates in cryptorchid boys were significantly higher than the preoperative and post-high ligation of hernial sac ones respectively in boys with oblique inguinal hernia(Pa0.05).Conclusion Cryptorchidism may induce an autoimmune response against sperm antigen in prepuberty independent of testicular location,orchiopexy,unilateral or bilateral cryptorchidism and deferens and(or) epididymis abnormality.

Objective When bacterial cellulose (BC) is used as a scaffold material in tissue engineering,the nano-structure of BC may not provide enough space for animal cell growth and differentiation which would not achieve a perfect application in tissue engineering.In order to solve this problem,a novel green approach is developed in this research to produce bacterial nanocellulose materials with micropores ranging 50-800 μm.Methods Several ratios of hydrogen peroxide to sodium chlorite were used to react instantly to produce a large number of bubbles in BC hydrogels,which formed micropores with diameters ranging 50-800 μm.Optical microscopy and scanning electron microscope were used to evaluate microporous BC hydrogels and verify the existence of micropores.Results The size of pores could be regulated along with the changes in the amount of reactants used in the experiment.Fourier transform infrared spectroscopy verified that no cellulose was oxidized.Water content of the microporous BC hydrogels was similar to that of the original BC hydrogels.The Young's modulus of microporous BC hydrogels was 26.1 kPa,which was lower than that of the original BC hydrogels (69.9 kPa).Thiazoyl blue tetrazolium bromide (MTT) test displayed a higher viability on the microporous BC hydrogels compared to the growth on the unmodified BC substrates.Conclusions This study provides a convenient and promising way to prepare microporous materials,which may not be limited to only BC material,but could be used in other hydrogels.The proposed approach is suitable for extensive industrialization.
