Objective To investigate the clinical effect of caffeine citrate combined with continuous positive airway pressure( CPAP) in the treatment of primary apnea of prematurity.Methods 80 premature infants with primary apnea who received therapy from January 2014 to August 2015 were selected as research subjects.According to ran-dom number table,the infants were divided into two groups equally.Besides conventional treatments,the control group received treatment of caffeine citrate,while the observation group received CPAP and caffeine citrate.Then,the cura-tive efficacy,situation of apnea and adverse reactions were compared.Results The total effective rate between the observation group and the control group had statically significant difference(95.0%vs.77.5%,P<0.05) .Compared with the control group,the observation group had statistically less seizure frequency,shorter duration of seizure and disappearance time of symptoms(all P<0.05).During the treatment,incidence rates of tachycardia,dysphoria and electrolyte disturbance in the observation group were statistically lower than those in the control group (all P<0.05), while the incidence of feeding intolerance in the two groups had no statistically significant difference ( P >0 .0 5 ) . Conclusion Caffeine citrate in combination with CPAP is effective for primary apnea of prematurity,which can sig-nificantly increase curative efficacy,lessen seizure frequency of apnea,shorten duration of seizure and disappearance time of symptoms with less adverse reactions.

Objective To investigate and analyze the status quo of the patients of extended stay at 11 clinical hospitals of a general university in Beijing, and explore the countermeasures and solutions.Methods Contact with the medical affairs departments of these hospitals to collect information about such patients of extended stay.Results A total of 43 cases of patients were identified as extended stay at these hospitals, accounting for 0.00% to 0.93% of total beds.Their stay ranged from 1 month to 15 years, including 17 cases with medical disputes (39.5%), and 26 cases without (60.5%).Conclusions The phenomenon of extended stay at hospitals deserve enough attention and appropriate actions accordingly.

Objective To compare the influence of cryopreservation duration on quality of rozen-thawed embryo and clinical outcome in frozen-thawed transfer cycles. Methods A retrospective study was performed to evaluate the clinical outcomes and quality of rozen-thawed embryo of frozen embryo transfer(FET)cycles includ-ing freezing cycles and vitrification cycles. FET cycles were divided into 4 group acorrding to the storage duration of vitrified embryos:1~6 months group ,7~12 months group ,13~24 months group and ≥ 25 months group. Result There was no significant difference in recovery rate ,clinical pregnancy rate and abortion rate (98.1%, 99.0%,96.8%&95.7%;54.4%,55.4%,49.6%&51.5%;0.7%,8.9%,9.4%&11.1%;P>0.05). The embryos recovery rate and clinical pregnant rate after vitrification were significantly higher than programmed freezing (P<0.05). The blastocyst recovery rate in group A was significantly higher than the cleavage stage embryo recov ery rate in group B(P<0.05). Conclusions Vitrification has better effects on cryopreservation and clinical outcomes. Blastocyst may be the best stage for vitrifying and freezing of embryo.

Objective To evaluate the curative effect on chdecytolithiasis with Chinese traditional patent formulation Qingdanyin and ESWL. Methods From January 2000 to January 2003,332 patients with gallstones were treated with Qingdanyin and ESWL, compared with 141 patients with routine ESWL. Results The 2-week clean rate(36.14%),one month clean rate(58. 58%),3-month clean rate(68. 98%) ,6-month clean rate(86.75%) of gallstones in the Qingdanyin and ESWL group were much higher than those in routine ESWL patients(14. 92%, 21.02%,35.93%,47.11%,respectively)(P

OBJECTIVE To study the sterilization method for on-wall oxygen humidifying inhalation sets in hospital.METHODS The different parts of on-wall oxygen humidifying inhalation sets were sterilized with Jianzhishu disinfectant and Andofo povidone iodine disinfectant liquid.RESULTS The regular percents for bacterial examination of the different parts of oxygen humidifying inhalation sets after sterilization were higher than before,P

OBJECTIVE To study the sterilization effect of on-wall oxygen humidifying inhalation sets.METHODS The different parts on on-wall oxygen humidifying inhalation sets were sterilized,then compared the result before and after sterilization.RESULTS The regular percents for bacterial examination of humidifying bottle were 17.14% before sterilization,and 100.00% after sterilization,the regular percents for bacterial examination of metallic guilloche were 34.29% before sterilization and 94.29% after sterilization,the regular percents for bacterial examination of vent tube in humidifying bottle were 8.57% before sterilization,and 97.14% after sterilization.The regular percents for bacterial examination of the different parts of oxygen humidifying inhalation sets after sterilization were higher than before it P

OBJECTIVE:To offer the literature basis for clinical safe drug use by literature research about ADR induced by Yishen juanbi pill. METHODS:Using“Yishen juanbi pill”as searching word,related literatures about ADR induced by Yishen juanbi pill were collected from CNKI,and then the occurrence of ADR was summarized and analyzed. RESULTS:A total of 15 literatures were included,involving 58 patients. Primary disease were mainly rheumatoid arthritis (28 cases,48.28%);organs/systems involved in ADR were digestive system (77 cases, 76.24%). Main clinical manifestations were epigastric discomfort, pernicious vomiting,diarrhea,etc. No obvious ADR was found. ADR-inducing dose was mainly 8 g,tid(47 cases,92.16%);ADR-inducing drug combination were two-drug combination (33 cases,56.90%). Fifty-eighe cases of ADR were recovered after treatment,and main treatment was drug withdrawal or symptomatic treatment. CONCLUSIONS:Although Yishen juanbi pill may induce ADR,those ADR can disappear spontaneously after drug withdrawal or the symptoms are recovered after symptomatic treatment. Yishen juanbi pill is a relatively safe Chinese patent medicine of anti-inflammatory,but ADR monitoring should be strengthened during application.

Objective To explore the treatment of thromboangitis obliterans (TAO) of lower extremities.Methods From March 1994 to February 2009,24 cases (26 limbs) affected by chronic ischemia were diagnosed as TAO by Doppler ultrasound and DSA,CTA or MRA.According to the different levels of the extensive and diffuse arterial occlusion,the revascularization was performed in the ways:19 cases (21 limbs) underwent venous arterialization,3 cases (3 limbs) underwent endovascular therapy,and 2 cases (2 limbs) underwent thrombectomy.ResultsAfter the venous arterialization,19 cases (21 limbs) were followed up for 1 to 14.5 years.Apart from the 5 limbs amputation (23.8%),the postoperative results of the most limbs were satisfactory (61.9%).The ABI before therapy (0.38?0.11) was significantly lower than that 6 months after therapy (0.79?0.08),P

Objective To investigate the management of acute limb ischemia.Methods The clinical data of 28 patients with acute limb ischemia were retrospectively analyzed.Four patients with arterial embolism underwent embolectomy.one patient with pseudoaneurysm underwent false aneurysm resection and revascularization with PTFE,23 patieuts wiht arterial occlusive disease were treated by multiple means such as embolectomy,bypass,primary amputation,endovascular interventions,and pharmacologic therapy(n=23).Results The 5 patients with arterial embolism or pseudoaneurysm were all treated successfully.In the 23 patients with arterial occlusive disease,5(21.7%) were treated successfully,12(52.2%) were improved,and 6(26.1%) had ineffective treatment.No inpatient died,but 4 patients underwent amputation.During follow-up of 6-45 months,there were 4 deaths and other 5 amputations.Conclusions Proper intervention of patients with acute limb ischemia should be chosen according to clinical evaluation of the illness,and includes embolectomy and revascularization,to get limb or life salvage.
