Objective To compare the effect of application of constant speed injection pump and manual injection on hysterosalpi-nography (HSG).Methods A total of 220 infertile patients were selected and classified into experimental group and control group. Then the patients were scheduled to undergo HSG.The experimental group was undergone constant speed pump injection and control group manual injection.Observe the effectiveness of the two methods on patients in two groups,respectively.Results The excellent rate of the images in experimental group (94.55%)was significantly higher than the control group (85.45%)and the risk of adverse reactions were significantly decreased in the former.There was statistical difference between the two groups.Conclusion Constant speed infusion pump is a convenient,safe and effective method in hysterosalpinography compared with manual injection,which is worthy of application in clinic.

This study was aimed to explore the clinical efficacy of Shen-Kang Injection (SKI) combined with hemodialysis in the treatment of chronic renal failure (CRF) patients. A total of 41 end-stage CRF patients under the hemodialysis treatment were randomly divided into the SKI treatment group of 19 cases and a control group of 22 cases. Both groups were treated with standard dialysis and the hemodialysis was maintained in the same symp-tomatic treatment conditions. Patients in the control group underwent three hemodialysis treatments in one week, while those in the treatment group were given hemodialysis twice a week based on the symptomatic treatment. And SKI was given after each time of hemodialysis in the treatment group. Indexes and changes in serum creati-nine (Scr), blood urea nitrogen (BUN) level, dialysis adequacy, nutrition status, traditional Chinese medicine ( TCM ) syndrome and other aspects of both groups were observed . The results showed that in the treatment group and control group, there were no significant differences in the renal function, dialysis adequacy, nutrition indica-tors and electrolyte ( P > 0 . 05 ) . In the treatment group , the total efficiency of TCM syndrome was 84 . 21%. And the total efficiency of TCM syndrome in the control group was 45.45%. The treatment group was better than the control group (P < 0.05). Symptoms such as scaly dry skin, numbness of the four limbs and dry stool were not obviously improved . And there was no statistical significance ( P > 0 . 05 ) . Symptoms such as fatigue , shortness of breath, poor appetite, dizziness, headache, lower back pain and spontaneous sweating were improved significantly. And there was statistical significance ( P < 0 . 05 ) . The treatment group was better than the control group . There were no abnormalities in the routine tests of blood, urine and stool, electrocardiogram, liver function, renal func-tion and electrolyte. In the treatment group, there was no significant adverse reactions during patients received SKI. The SKI has good safety. It was concluded that SKI combined with hemodialysis in the treatment of CRF is able to improve the clinical symptoms of patients and improve the patients' quality of life. When patient received adequate dialysis, SKI may reduce the dialysis frequency per week.

Objective To compare the effects of snfentanil and fentanyl combined anesthesia on stress responses in pediatric patients undergoing surgical repair of congenital heart defect with cardiopulmonary bypass (CPB) .Methods Twenty-four pediatric patients aged 2-6 yr undergoing surgical repair of congenital heart defect were randomized into 2 groups (n=12 each): sufentanil combined anesthesia group (group S) and fetanyl combined anesthesia group (group F). The patients were premedicated with intramuscular morphine 0.2 mg/kg, scopolamine 0.01 mg/kg and ketamine 5 mg/kg. Anesthesia was induced with midazolam 0.1 mg/kg and snfentanil 0.7 μg/kg (in group S) or fentanyl 5 μg/kg (in group F). Tracheal intubation was facilitated with vecuronium 0.15 mg/kg. The patients were mechanically ventilated. PCO_2 was maintained at 35-45 mm Hg. Anesthesia was maintained with propofol infusion at 6-9 mg·kg~(-1)·h~(-1) and intermittent in boluses of midazolam,vecuronium and 3 doses of sufentanil (0.7, 1.5, 1.5 μg/kg) or fentanyl (5, 10, 10 μg/kg). Arterial blood samples were taken after entering the operation room, at 1 min after tracheal intubation, 1 min after splitting of sternum, immediately after rewarming, 10 min after termination of CPB and 24 h after operation for determination of plasma ACTH, cortisol, glucagon, lactic acid and blood glucose. Results The MAP and HR were maintained in the normal range during operation in both groups. The plasma concentrations of ACTH, cortisol, glucaon and lactic acid were significantly lower in group S than in group F. Plasma ACTH cortisol, glucagon, lactic acid and blood glucose increased significantly during operation as compared with the baseline before anesthesia in both groups. Conclusion Sufentanil combined anesthesia can inhibit stress response in pediatric patients more effectively during surgical repair of congenital cardiac defect performed under CPB.

Objective:To investigate the clinical efficacy of low-set perforating branch propeller flap of fibular artery for repairing calcaneal soft tissue defects.Methods:A retrospective case series study was conducted on 28 patients with calcaneal soft tissue defects admitted to 920th Hospital of Joint Logistics Support Force of PLA from January 2013 to December 2019. There were 19 males and 9 females，aged 13-69 years［（33.8±13.7）years］. The size of soft tissue defects ranged from 5 cm×2 cm to 18 cm×12 cm，and the size of flaps ranged from 12 cm×4 cm to 24 cm×10 cm. The soft tissue defects were repaired with the low-set fibular artery perforator propeller flap after emergency debridement or flap transplantation at the second stage after debridement according to the wound surface conditions. The survival of the flap，wound healing at the recipient and donor sites and complications were recorded. The function of the affected ankle was assessed according to American Orthopedic Foot and Ankle Society（AOFAS）ankle-hindfoot score before operation and at the final follow-up. The degree of satisfaction of flap appearance was assessed by Thankappan flap appearance satisfaction score at the final follow-up.Results:All patients were followed up for 2-40 months［（17.4±5.9）months］. All flaps survived and wounds at both donor and recipient sites were healed well，with satisfactory color and texture of the flaps，without thinning operation performed. Three patients experienced numbness on both sides of the incision at donor sites within 1 week after operation and returned to normal on their own about 2 months after operation，with all flaps restoring partial light pain sensation 1 year after operation. No complications occurred such as blood flow disorder of the affected limb or compartment syndrome. The AOFAS ankle-hindfoot score was 56-95 points［（82.3±15.2）points］at the final follow-up，significantly higher than the preoperative score of 17-68 points［（35.7±13.4）points］（ P<0.01）. The results were excellent in 21 patients，good in 5 and fair in 2，with excellent and good rate of 93%.The appearance satisfaction score was 4-10 points［（7.6±2.9）points］according to Thankappan flap appearance satisfaction score. The results were excellent in 6 patients，good in 15 and fair in 7，with the excellent and good rate of 75%. Conclusions:The low-set perforating branch propeller flap of fibular artery for reconstruction of calcaneal soft tissue defects has advantages of reliable blood supply and high survival rate of the flap as well as good restoration of the appearance and function of the affected limb.
