Objective:To compare the effects of brinzolamide-timolol (B&T) eye drops and dipivefrine hydrochloride (DH) eye drops on the intraocular metabolism of ranibizumab after intravitreal injection in rabbit.Methods:Eighteen New Zealand white rabbits were randomly and equally divided into DH group, B&T group, and control group.The right eye was selected as the experimental eye.The B&T and DH groups received DH and B&T eye drops, respectively, twice daily, 30 μl each time.The control group did not receive any treatment.Intraocular pressure (IOP) was measured in both eyes before the first administration and 1 hour after the first administration on the second day.After IOP measurement, the experimental eye received an intravitreal injection of 0.25 mg ranibizumab (10 mg/ml).Aqueous humor samples were collected 1, 3, 7, 10, 14, 21 and 28 days after injection.Ranibizumab concentration in the aqueous humor was measured by ELISA kit.Pharmacokinetic parameters including time to peak concentration ( tmax), peak concentration ( Cmax), elimination half-life ( t1/2) and area under the concentration-time curve (AUC) of ranibizumab were calculated.This experiment was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECA-2023-03). Results:The tmax of ranibizumab in the aqueous humor was 1 day in all three groups.The Cmax values in the control, B&T and DH groups were (8.122±2.445), (13.079±3.140) and (8.299±0.899)μg/ml, respectively.Except for day 3 in the control group, the ranibizumab concentrations in aqueous humor of the B&T group were higher than that of the DH group and the control group at all time points after injection, with statistically significant significances (all P<0.05).The t1/2 of ranibizumab in aqueous humor in the control group, B&T group, and DH group were (2.90±0.29), (3.36±0.35) and (2.80±0.29) days, respectively, and the AUC0-t values were (52.697±10.178), (80.244±11.249) and (51.985±8.734)μg/ml·d, respectively.The t1/2 and AUC0-t of ranibizumab in aqueous humor of the B&T group were significantly higher than those of the DH group and the control group, and the differences were statistically significant (all P<0.05).The mean bioavailability in the B&T group was increased by 52.3% compared to the control group. Conclusions:B&T eye drops prolong the half-life and enhance the intraocular bioavailability of ranibizumab after intravitreal injection in rabbits, whereas DH has no significant effect on its intraocular metabolism.

Objective:To improve the differential awareness of lead porsoning.Methods:A case with stomachache, anemia, myasthenia, and abnormal urine color was described. The diagnosis and treatment were analyzed and discussed.Results:A middle-aged female was admitted with a 9-month medical history, compalnied with rash, stomachache. She also had evidence of hemolytic anemia,nervous system and kidneys imvolvement, and Lab test showed a significantly elevated blood lead level. It was considered to be in line with multiple organ system damage caused by lead poisoning.Conclusion:Lead poisoning can mimic the clinical presentations of rheumatic diseases, resulting in multiple system ivolvement. When the patient's clinical manifestation cannot be fully explained, some special situations should be considered, such as toxic testing.

Objective:To explore surgical techniques and summarize surgical experience of the paraumbilical flap pedicled with deep inferior epigastric vessels for the repiration of soft tissue defects in pelvic area.Methods:Between August, 2006 and August, 2018, 8 patients with soft tissue defects and bone exposure were treated with paraumbilical flap pedicled with deep inferior epigastric vessels. There were 6 males and 2 females with the average age of 35.3 (range, 12-47) years. The defects were caused by car accident in 5 cases, by high falling injury in 1 case, by soft tissue necrosis after malignant schwannoma resection in 1 case, and by soft tissue necrosis after pelvic operation of open reduction internal fixation in 1 case. The defects located at iliac spine in 5 cases, at tuber ischii in 1 case, and at buttock and perineal region in 1 case. The size of the wounds ranged from 11.0 cm×6.0 cm to 22.0 cm×8.0 cm. The size of the flaps ranged from 13.0 cm×7.0 cm to 29.0 cm×12.0 cm. The followed-up was made by outpatinet service, telephone or WeChat.Results:All flaps survived, and the wound infection was controlled. The followed-up time ranged from 12 to 46 (mean 26) months. All flaps survived uneventfully, and the texture and elasticity of the flaps were good. There were no recurrence of infection, and no ventral hernias occurred in donor sites.Conclusion:The transfer of paraumbilical flap pedicled with deep inferior epigastric vessels is a reliable method to repair large soft tissue defects in iliac spine, perineal region, buttock and tuber ischii.

Objective: To summarize the measures and experience of treatment in mass extremely severe burn patients. Methods: The clinical data and treatment of 8 extremely severe burn patients in August 2 Kunshan factory aluminum dust explosion accident who were admitted in the 100th Hospital of PLA on August 2nd, 2014, were retrospectively analyzed. There were 4 males and 4 females, aging 22-45 (34±7) years, with total burn area of 55%-98% [(89±15)%] total body surface area (TBSA) and full-thickness burn area of 45%-97% [(80±21)%] TBSA. All the 8 patients were accompanied with severe shock, inhalation injury, and blast injury. According to the requirements of former PLA General Logistics Department and Nanjing Military Command, a treatment team was set up including a special medical unit and a special care unit, with Chai Jiake from the First Affiliated Hospital of PLA General Hospital as the team leader, Zheng Qingyi from the 175th Hospital of PLA (the Affiliated Dongnan Hospital of Xiamen University) as the deputy leader, the 100th Hospital of PLA as the treatment base, and burn care, respiratory, nephrology, nursing specialists from the First Affiliated Hospital of PLA General Hospital, and the burn care experts and nursing staff from the 180th Hospital of PLA, 118th Hospital of PLA, 98th Hospital of PLA, and 175th Hospital of PLA, and nurses from the 85th Hospital of PLA, 455th Hospital of PLA, 101th Hospital of PLA, 113th Hospital of PLA as team members. Treatment strategies were adopted as unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns. With exception of one patient who received deep vein catheterization before admission, the other 7 patients were treated with deep vein catheterization 0.5 to 3.0 hours after admission to correct hypovolemic shock as soon as possible. Eight patients received tracheotomy, and 7 patients were treated with mechanical ventilation by ventilator in protective ventilation strategy with low tide volume and low volume pressure to assist breathing. Fiberoptic bronchoscopy was done one to three times for all the 8 patients to confirm airway injuries and healing status. Escharectomy and Meek dermatoplasty in the extremities of all the 8 patients were performed 3 to 6 days after injury for the first time. Escharectomy, microskin grafting, and covering of large pieces of allogeneic skin on the trunks of 4 patients were performed 11 to 16 days after injury for the second time. The broad-spectrum antibiotics were uniformly used at first time of anti-infective therapy, and then the antibiotics species were adjusted in time. The balance of internal environment was maintained and the visceral functions were protected. One special care unit was on responsibility of only one patient. Psychological intervention was performed on admission. The rehabilitative treatment was started at early stage and in company with the whole treatment. Results: Acute renal injury occurred in 5 patients within 36 hours after injury and their renal function was restored to normal 4 days after injury due to active adjustment of fluid resuscitation program. No pulmonary complications, such as severe pulmonary infection and ventilator-associated pneumonia, occurred in the survived patients. One of the 8 patients died, and the other 7 patients were cured successfully. The wounds were basically healed in 2 patients in 26 or 27 days by 2 or 3 times of operation, and in 5 patients by 4 or 5 times of operation. The basic wound healing time was 26-64 (48±15) days for all the 7 patients. Conclusions Treatment strategies of unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns are the bases to successful treatment. Correcting shock as soon as possible is the prerequisite and closing wound as soon as possible is the key to successful treatment. Comprehensive treatment measures, such as maintaining and regulating the function of viscera, improving the body immunity, and preventing and treating the complications, are the important components to successful treatment. It is emphasized that in the treatment of mass extremely severe burn patients, specialist burn treatment should always be in the dominant position, and other related disciplines may play a part in auxiliary function.

Objective: Study of the results and the degree on occupational noise-induced deafness in-to the different high frequency hearing threshold weighted value, in order to provide theoretical basis for the re-vision of diagnostic criteria on occupational noise-induced deafness. Methods: A retrospective study was con-ducted to investigate the cases on the diagnosis of occupational noise-induced deafness in Guangdong province hospital for occupational disease prevention and treatment from January 2016 to January 2017. Based on the re-sults of the 3 hearing test for each test interval greater than 3 days in the hospital, the best threshold of each frequency was obtained, and based on the diagnostic criteria of occupational noise deafness in 2007 edition, Chi square test, t test and variance analysis were used to measure SPSS21.0 data, their differences are tested among the means of speech frequency and the high frequency weighted value into different age group, noise ex-posure group, and diagnostic classification between different dimensions. Results: 1. There were totally 168 cases in accordance with the study plan, male 154 cases, female 14 cases, the average age was 41.18 ±6.07 years old. 2. The diagnosis rate was increased into the weighted value of different high frequency than the mean value of pure speech frequency, the weighted 4 kHz frequency increased by 13.69% (χ²=9.880, P=0.002) , 6 kHz increased by 15.47% (χ²=9.985, P=0.002) and 4 kHz+6 kHz increased by15.47% (χ²=9.985, P=0.002) , the difference was statistically significant. The diagnostic rate of different high threshold had no obvious differ-ence between the genders. 3. The age groups were divided into less than or equal to 40years old group (A group) and 40-50 years old group (group B) , there were higher the diagnostic rate between high frequency weighted 4 kHz (A group χ²=3.380, P=0.050; B group χ²=4.054, P=0.032) , weighted 6 kHz (A group χ²=6.362, P=0.012; B group χ²=4.054, P=0.032) , high frequency weighted 4 kHz+6 kHz (A group χ²=6.362, P=0.012; B group χ²=4.054, P=0.032) than those of speech frequency average value in the same group on oc-cupational noise-induced deafness diagnosis rate, the difference was statistically significant. There was no sig-nificant difference between age groups (χ²=2.265, P=0.944) . 4. The better ear's mean value of pure speech fre-quency and the weighted values into different high frequency of working years on each group were compared, working years more than 10 years group was significantly higher than that of average thresholds of each frequen-cy band in 3-5 group (F=2.271, P=0.001) , 6-10 group (F=1.563, P=0.046) , the difference was statistically significant. The different high frequency weighted values were higher than those of the mean value of pure speech frequency, and the high frequency weighted 4 kHz+6 kHz had the highest frequency difference, with an average increase of 2.83 dB. 5. The diagnostic rate into weighted different high frequency was higher in the mild, moderate and severe grades than in the pure speech frequency. In the comparison of diagnosis for mild occupational noise-induced deafness, in addition to the weighted 3 kHz high frequency (χ²=3.117, P=0.077) had no significant difference, the weighted 4 kHz (χ²=10.835, P=0.001) , 6 kHz (χ²=9.985, P=0.002) , 3 kHz+4 kHz (χ²=6.315, P=0.012) , 3 kHz+6 kHz (χ²=6.315, P=0.012) , 4 kHz+6 kHz (χ²=9.985, P=0.002) , 3 kHz+4 kHz+6 kHz (χ²=7.667, P=0.002) were significantly higher than the diagnosis rate of the mean value of pure speech frequency. There was no significant difference between the two groups in the moderate and se-vere grades (P>0.05) . Conclusion Bring into different high frequency hearing threshold weighted value in-creases the diagnostic rate of occupational noise-induced deafness, the weighted 4 kHz, 6 kHz and 4 kHz+ 6 kHz high frequency value affects the result greatly, and the weighted 4 kHz+6 kHz high frequency hearing threshold value is maximum the effect on occupational noise-induced deafness diagnosis.
