? AIM: To analyze clinical characteristics and postoperative outcomes after open globe injury.?METHODS: Demographic characteristics ( age, gender, eye trauma, profession, cause of injury and injured part ) , as well as complications and prognosis were analyzed in 152 cases (152 eyes) of open globe injury.? RESULTS: Patients with open globe injury had an average age of 40. 45±38. 32 years old with a 5. 9:1 male-to-female gender ratio. The left-to-right eye ratio was 1. 27:1. Most patients were workers, farmers, or retired. The most common etiologies were scratches, boxing, and falls. Zone Ⅲ was the most commonly injured part. Iridoptosis or iris incarceration, retinal detachment, vitreal prolapse, hyphema or hypopyon, and vitreous hemorrhage were the most common complications. Visual acuity improved in 86 cases postoperatively but ophthalmectomy was still required in 25 eyes.?CONCLUSION: Vision can be improved after surgery in open globe injury. However, patients are usually seriously injured and improvement is minimal, thereby resulting in a great loss to patients and society.

Idiosyncratic adverse drug reactions (IDR) induce severe medical complications or even death in patients. Alert structure in drugs can be metabolized as reactive metabolite (RM) in the bodies, which is one of the major factors to induce IDR. Structure modification and avoidance of alert structure in the drug candidates is an efficient method for reducing toxicity risks in drug design. This review briefly summarized the recent development of the methodologies for structure optimization strategy to reduce the toxicity risks of drug candidates. These methods include blocking metabolic site, altering metabolic pathway, reducing activity, bioisosterism, and prodrug.

Objective To observe the adverse reaction of dexmedetomidine(Dex)combined with dezocine in gynecological laparoscopic surgery after general anesthesia.Methods 120 cases of gynecologic laparoscopic surgery,ASA Ⅰ-Ⅱ,according to random number table method were divided into three groups,40 cases in each group.A group was intravenously injected Dex 1μg/kg 10min before induction,intravenously injected dezocine 5mg+ ondansetron 4mg 30min before the end of the operation.B group was intravenously injected dezocine 5mg+ ondansetron 4mg 30min before the end of surgery.C group was intravenously injected saline 1mL+ ondansetron 4mg.Before induction(T0),5min before extubation(T1),extubation(T2),10min after extubation(T3),the MAP,HR,SpO2 of three groups were recorded.The postoperative recovery time,degree of agitation,extubation and Ramsay sedation score,VRS analgesia 24h score,postoperative adverse reaction were compared among three groups.Results There was no difference in the recovery time among the three groups(t=0.94,0.97,1.02,all P>0.05).Compared with T0,the MAP of the three groups at the time of T2 increased,but the MAP of B group and C group was significantly higher(t=4.65,5.201,all P<0.01),HR was significantly higher(t=2.382,2.915,all P<0.05).Compared with A group and B group,the agitation rate of C group was higher(u=5.54,3.47,all P<0.01).The ramsay sedation score of 1 in A group was lower than C group,the VRS score of painless rate in A,B group was higher than that of C group(all P<0.05).Postoperative 24h,there were 19,23,24 cases of the three groups with nausea and vomiting,and the incidence rates were 47.5%,57.5%,60%,respectively,the differences were not statistically significant among the three groups(all P>0.05).Conclusion General anesthesia in gynecological laparoscopic surgery using Dex combined with dezocine can make patients more stable circulation,improve patients'' recovery quatity,it is a safe and effective method for prevention of adverse reaction after general anesthesia.

Objective To explore the safety of fat reduction treated by non invasive focused ultrasound.Methods A randomized double-blind and negative control clinical trial was carried out on the excess fat of 40 subjects' abdomen by a JCS-01 non-invasive focused ultrasound device.Subjects received treatments with the device on day 1 and day 7.Observations on the area treated and inquiries on feelings were conducted during treatments.Before the first treatment and 14 days after the treatment,laboratory examinations were performed,including liver function,blood lipid tests,etc.Results 40 subjects participated in the trial and 36 subjects (18 each in both treatment and control groups) accomplished 2 times of treatments,all followed-up and laboratory examinations.During the process of treatments,4 subjects in the experimental group complained about feelings of tepidity or pricking.One subject on blood test of triglyceride showed slightly higher than her early normal result,which fell to the normal level at reexamination.Conclusions Subjects treated by non-invasive focused ultrasound at the area of no more than 500 cm2 every time and at an interval of 6 days manifest little changes on the blood test results,with slightly local reactions but no complaints during follow-up.

Objective To explore the function of autonomic nerves system in children with congenital heart disease (CHD) combined with paroxysmal supraventricular tachycardia (PSVT). Methods Fifty children having PSVT and no CHD (PSVT group), 30 children with both PSVT and CHD (CHD group), and 50 cases of healthy children (control group) were selected. The difference of 24-hour heart rate variability (HRV) among three groups was analyzed retrospectively. Results There were statistical differences in the long-range time domain HRV indexes, including SDNN, SDANN, SDNN Index, pNN 50 , and RMSSD among three groups (F=80.32-?263.18, P all?0.01). The SDNN, pNN50, and RMSSD in PSVT group were significantly decreased compared with control group (P all?0 . 05 ), and the SDANN and SDNN Index in PSVT group were decreased but the difference was not statistically significant compared with control group (P all?>?0.05). The SDNN, SDANN, SDNN Index, pNN50, and RMSSD were signiifcantly decreased in CHD group compared with PSVT group (P all?0 . 05 ). Conclusions Children with PSVT have the imbalanced autonomic nerves system which mainly manifests as decreased vagal function, and, if combined with CHD, have the increase of sympathetic nerve tension.

Objective:To determine the related substances in benzalkonium chloride used as a pharmaceutical adjuvant, and com-pare the quality at home and abroad. Methods:An HPLC method was used with an ODS-HYPERSIL C18 column(250 mm × 4. 6 mm, 5 μm). The detection wavelength was 210 nm and 257 nm. The flow rate was 1. 0 ml· min-1 and the column temperature was 30℃. The injection volume was 20 ml. The mobile phase was A ( dissolving 1. 09 g sodium1-hexanesulfonate and 6. 9 g sodium dihydrogen phosphate in water, adjusting pH to 3. 5 with phosphoric acid and diluting to 1 000. 0 ml) and B ( methanol) with gradient elution. Results:The content of benzaldehyde in the samples at home and abroad was low. The content of benzyl alcohol in the samples from a-broad was qualified, which was significantly higher than that in the domestic samples. The content of benzyl chloride in the domestic samples was higher than that in the samples from abroad. Conclusion:The method is simple and fast, which is suitable for comparing the related substances of domastic and imported samples. At the same time, the study provides basis for enterprises to choose benzalko-nium chloride rationally.
