ABSTRACT
Objective: To explore the effect of vidian neurectomy and selective vidian neurectomy in the treatment of moderate and severe persistent allergic rhinitis (AR). Methods: A total of 60 patients with moderate-to-severe persistent AR treated in Zhejiang Provincial Hospital of Integrated Traditional Chinese and Western Medicine from June 2018 to June 2020 were selected, including 28 males and 32 females. A total of 40 cases in the observation group were subjected to vidianneurectomy, while, 20 cases in the control group underwent selective vidianneurectomy. Patients in the two groups were followed up at 6 months, 1 year, and 2 years, respectively, and evaluated according to AR diagnostic and efficacy assessment criteria. Four symptoms of sneezing, clear runny nose, nasal congestion, and nasal itching were scored as efficacy indices before and at 6 months, 1 year, and 2 years after surgery. The regression of the lower turbinate swelling after surgery was assessed by nasal endoscopy or sinus CT. Postoperative tear secretion was followed up in both groups, and patients with dry eyes were counted in combination with ocular symptoms. SPSS 19.0 software was used to statistically analyze the data before and after the surgery and between the two groups. Results: The preoperative, 6-month, 1-year, and 2-year postoperative inferior turbinate signs were (2.73±0.45), (1.20±0.41), (1.25±0.49) and (1.30±0.56) points in the observation group and (2.75±0.44), (1.45±0.69), (1.75±0.72) and (1.90±0.85) points in the control group, respectively, with a statistically significant difference in the between-subjects effect test between the two groups (F=8.28, P<0.05), indicating a more durable surgical effect in the observation group. The total effective rate at 2 years after surgery was 95.0% (38/40) in the observation group and 50% (10/20) in the control group. The difference between the two groups by Fisher's exact test was statistically significant. No dry eye patient was found in either group at a 1.5-year postoperative follow-up. Conclusion: Both vidianneurectomy and selective vidianneurectomy have good recent treatment effects, vidianneurectomy has better long-term curative effects than selective vidianneurectomy.

Objective Laryngeal and upper esophageal foreign bodies are common diseases, we explored a new and simple method to remove these foreign bodies. Methods The clinical data of 177 patients with laryngeal and upper esophageal foreign bodies from June 2008 to January 2016 were analyzed retrospectively. We used two methods to treat these foreign bodies:130 foreign bodies were directly removed under video endoscopy;47 foreign bodies were removed with suspension laryngoscopy, and video endoscopy was used meanwhile. Result 177 laryngeal and upper esophageal foreign bodies were removed well, without severe complications like esophageal perforation or phyryngeal fistula. Conclusion Removing esophageal and laryngeal foreign bodies with video endoscopy is simple, safe and effective.
ABSTRACT
Objective To investigate the therapeutic effect of nasal endoscope surgery on chronic sinusitis and nasal polyps in geriatric patients.Methods A total of 132 geriatric patients with chronic sinusitis and nasalpolyps underwent nasal endoscope surgery in our hospital from Jun.2010 to Jun.2014,and the therapeutic effect was investigated.Results In the 132 cases,92 cases were cured (69.7％).Therapeutic effects were excellent in 33 cases (25.0％),and invalid in 7 cases (5.3％).The total effective rate was 94.7％.The total effective rate was 100.0％ in type Ⅰ,97.4％ in type Ⅱ and 84.8％ in type Ⅲ.The total effective rate was higher in type Ⅰ and Ⅱ than in type Ⅲ (x2=3.506 and 6.218,P=0.035 and 0.012).Local complications occurred in 10 cases (7.6％),including 1 case with nasolacrimal duct injury,2 cases with orbital hematoma,5 cases with nasal adhesion,1 case with surgical cavity hemorrhage and 1 case with sinus atresia.Conclusions The therapeutic effects of nasal endoscopesurgery on chronic sinusitis and nasalpolyps are good in geriatric patients,especially in treating chronic sinusitis and nasalpolyps of type Ⅰ and Ⅱ,and the postoperative complications are less,which is worth clinical application.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of sensory neuropeptide substance P combined with epidermal stem cells (ESC) on wound healing and nerve regeneration in diabetic rats.</p><p><b>METHODS</b>ESC that had been isolated from SD rats were identified and cultured in vitro, and they were inoculated onto nourishing layer of amniotic membrane to construct amniotic membrane-ESC. Four full-thickness skin wounds were produced on the back of each of 48 diabetic rats. The resulted 192 wounds were randomly divided into ESC + substance P group, ESC group, substance P group, and control group according to the lottery method, with 48 wounds in each group. Wounds in ESC + substance P group and ESC group were transplanted with amniotic membrane-ESC, and those in substance P group and control group were transplanted with amniotic membrane. After transplantation, 250 µL substance P in the concentration of 1 × 10(-7) mol/L was injected around and into the middle of the wounds in ESC + substance P group and substance P group, 2 times a day, and continued for 4 days, while 250 µL PBS solution was injected in the above-mentioned position in ESC group and control group as control, 2 times a day, and continued for 4 days. On post injury day (PID) 4, 7, 10, 14, 17, and 23, the wound healing rate (with 8 wounds at each time point) was observed and determined, and changes in wound tissue structure were observed with HE staining. On PID 4, 7, and 10, collagen distribution in wound tissue was observed with Masson staining, and type I and type III collagen deposition in wound tissue was respectively observed after immunohistochemical staining. The distribution of protein gene product 9.5 (PGP 9.5) and regeneration of substance P positive nerve fibers in wound tissue were observed with immunohistochemical staining on PID 14 and 23. Data were processed with one-way analysis of variance and t test.</p><p><b>RESULTS</b>(1) The wound healing rate in ESC + substance P group reached 100.0% on PID 14, which was obviously earlier than that in ESC group, substance P group, and control group, healing was respectively observed on PID 17, 17, and 23. The wound healing quality in ESC + substance P group was better than that in the other three groups as shown by HE staining. (2) On PID 10, collagen that was darkly stained and widely distributed was observed in wound tissue of ESC + substance P group and substance P group, while collagen in the other two groups was lightly stained and narrowly distributed. Deposition quantity of type I collagen gradually increased, and that of type III collagen gradually decreased in the wounds of each group over time. On PID 4, 7, and 10, distribution amount of type I collagen in wound tissue of ESC + substance P group was significantly higher than that in ESC group (with t value respectively 32.72, 118.21, 26.71, P values all below 0.01) and control group (with t value respectively 44.37, 22.76, 30.32, P values all below 0.01), while there was no significance between ESC + substance P group and substance P group. On PID 4, 7, and 10, distribution amount of type III collagen in wound tissue of ESC + substance P group was significantly higher than that in ESC group (with t value respectively 32.27, 28.68, 14.51, P values all below 0.01) and control group (with t value respectively 35.68, 22.52, 22.24, P values all below 0.01). (3) A large amount of PGP 9.5 and regeneration of substance P positive nerve fibers, and some peripheral nerve fibers in deep wound extending to epidermis were observed in wound tissue of ESC + substance P group and substance P group. A small amount of PGP 9.5 and regeneration of substance P positive nerve fibers without peripheral nerve fibers extending to epidermis were observed in deep wound tissue of ESC group and control group. On PID 14, 23, ratios of area of PGP 9.5 positive nerve fiber in the wounds of ESC + substance P group were (3.86 ± 0.25)% and (7.03 ± 0.28)%, and they were significantly higher than those of ESC group [(1.48 ± 0.30)%, (3.01 ± 0.43)%, with t value respectively 23.95, 30.27, P values all below 0.01] and control group [(1.46 ± 0.23)%, (2.84 ± 0.29)%, with t value respectively 27.35, 40.32, P values all below 0.01]. On PID 14, 23, ratios of substance P positive nerve fiber area in the wounds of ESC + substance P group were (2.01 ± 0.14)% and (1.19 ± 0.11)%, which were obviously higher than those of ESC group [(0.85 ± 0.17)%, (1.34 ± 0.21)%, with t value respectively 20.50, 2.60, P < 0.05 or P < 0.01] and control group [(0.74 ± 0.15)%, (1.30 ± 0.17)%, with t value respectively 23.98, 2.41, P < 0.05 or P < 0.01].</p><p><b>CONCLUSIONS</b>Joint application of substance P and ESC can effectively promote healing of wound and nerve regeneration in diabetic rats.</p>
