OBJECTIVE:To explore the effectiveness and safety of pranoprofen combined with sodium hyaluronate in the treat-ment of moderate and severe dry eyes. METHODS:180 patients with moderate and severe dry eyes were divided into observation group and control group by random number table method,with 90 cases in each group. Control group was given Sodium hyaluro-nate eye drops,one drop each time,tid,and received physical therapy as cleaning eyelid,hot compress and glandulae tarsales mas-sage. Observation group was additionally given Pranoprofen eye drops,one drop each time,tid. A treatment course lasted for 2 weeks. The monocular corneal fluorescence staining score,break-up time of tear film(BUT),dry eye symptom scores,ShirmerⅠtest (SIT) before and after treatment,clinical efficacy and ADR were compared between 2 groups. RESULTS:2,4 weeks after treatment,monocular corneal fluorescence staining scores and dry eye symptom scores of 2 groups were significantly lower than be-fore treatment;BUT and SIT were significantly longer than before;those indexes after 4 weeks of treatment were significantly bet-ter than after 2 weeks of treatment;those indexes of observation group after 2,4 weeks of treatment were significantly better than those of control group at the same time,with statistical significance (P<0.05). The total effective rate of observation group was 94.44%,which was significantly higher than that of control group(78.89%),with statistical significance(P<0.05). Both groups suffered from eye irritation symptom to different extent,and no other severe complications was found. There was no statistical sig-nificance in eye irritation symptom score between 2 groups(P>0.05). CONCLUSIONS:For moderate and severe dry eyes,prano-profen combined with sodium hyaluronate can effectively control ocular inflammation and improve tear film stability. It shows defi-nite therapeutic efficacy and good safety.

Objective To investigate the clinical effect of radiofrequency ablation (RF) combined with digital subtraction angiography (DSA)-guided percutaneous ethanol injection sclerotherapy in the management of high-return flow venous malformation (VM).Methods Forty-one patients,who were diagnosed as high-return flow VM with clinical and radiographic evidence,were divided into the observation group (n=19) and the control group (n=22) using a random number table.All high-return flow VM patients received DSA-guided percutaneous ethanol injection sclerotherapy while the patients in observation group were given radiofrequency ablation.The clinical effect,treatment times and adverse effect of the two groups were analyzed.Results The effectiveness of the observation group was significantly higher than those of the control group [94.7％ (18/19) vs 81.8％ (18/22)].The facial paralysis occurred in three patients (13.6％) after ethanol injection in the control group,while the observation group had no facial nerve injury after treatment.The patients in observation group had significantly fewer numbers of ethanol injection.Conclusions RF can improve the efficacy of high-return flow VM and reduce the number of ethanol injection.The scheme is safe and effective.

Objective : To investigate the effect of tension on donor site recovery of modified forearm flaps (closed forearm donor site skin flaps). Methods : From October 2018 to April 2021, 12 patients with oral cancer underwent forearm flap repair at Xuzhou Central Hospital. Handgrip strength and wrist motion were recorded before surgery. During the surgical incision at the donor site of the forearm, the triangular full-thickness skin of the donor site was used to close part of the surgical incision, and the other part of the surgical incision was directly closed and sutured. Tension was measured with a tension meter during the surgical incision at the donor site. Patients were followed up after surgery to observe whether there were postoperative complications such as necrosis and poor healing of donor site wounds, as well as forearm grip strength, wrist range of motion and appearance satisfaction. Results: Among the 12 patients, there was only one elderly patient with postoperative necrosis near the wrist in the donor site skin, and the average tension of the patient was 0.65 kg; the lesion healed after dressing changes. All of the other patients recovered well without postoperative complications. The mean tension of 12 patients was (0.51 ± 0.05) kg. The preoperative and postoperative grip strength of 12 patients was (23.7 ± 10.3) kg and (22.3 ± 10.7) kg, respectively, and the difference was not statistically significant (t=5.872, P<0.001). The mean range of motion of the wrist was (47.6 ± 8.3)°, (45.8 ± 5.8)°; dorsiflexion (54.6 ± 3.2)°, (53.9 ± 2.3)°; radial deviation (37.0 ± 2.3)°, (36.1 ± 2.2)°; ruler deviation (27.1 ± 1.9)°, (26.4 ± 1.3)°, respectively. The t values were 1.64, 1.636, 2.116 and 1.412, and the P values were 0.129, 0.130, 0.058 and 0.186, respectively. All 12 patients were satisfied with the appearance of the donor site of the forearm. Conclusion When the average tension during suturing is less than 0.5 kg, there is a lower risk of complications at the donor site of the forearm one month after surgery, a lower risk of impaired donor site function, and a greater possibility of patient satisfaction with the appearance of the donor site.
