ABSTRACT
Objective@#To explore the clinical manifestation and treatment strategy for descending necrotizing mediastinitis (DNM).@*Methods@#A total of 27 cases diagnosed as DNM from January 2010 to August 2018 in the First People’s Hospital of Foshan were reviewed. There were 16 males and 11 females, age ranged from 16 to 84 years. The clinical data were collected. SPSS 16.0 software and chi square test were used for statistical analysis.@*Results@#ALL 27 cases were diagnosed as DNM by contrast-enhanced CT scan of the neck and chest. Among the 27 cases, 13 cases resulted from peritonsillar abscess, 8 cases from esophageal foreign body perforation, 5 cases from parapharyngeal and retropharyngeal space abscess, and one case from infection of oral cavity. These 27 cases were divided into three subtypes according to the sites of mediastinitis, including 11 cases for typeⅠ, 5 cases for type ⅡA and 11 cases for type ⅡB. Of 27 cases, 20 cases underwent transcervical drainage for DNM, of which 5 cases with tracheotomy and 6 cases with thoracic drainage, and finally 19 of the 20 patients were cured, and one patient died of bacteremia; 7 cases refused to received surgery and were routinely treated with antibiotics, of which, one case was cured and 6 cases died. The curative rate in patients underwent surgery was significantly higher than that in patients treated with medication (χ2=13.638, P<0.001). Among the 20 cured cases, 4 cases were combined with diabetes mellitus and 6 cases with necrotizing fasciitis, while in the 7 died cases, 5 cases were combined with diabetes mellitus and 6 cases with necrotizing fasciitis. The comorbidity rates of diabetes mellitus (χ2=4.074, P=0.044) and necrotizing fasciitis (χ2=4.457, P=0.035) in died cases were significantly higher than those in cured cases.@*Conclusion@#DNM is a serious infection, with high mortality especially in patients with diabetes and necrotizing fasciitis. Timely cervical and chest enhanced CT scan play vital role in its diagnosis. DNM can be treated effectively with transcervical drainage.
ABSTRACT
Objective@#To study the clinical outcome of transoral CO2 laser surgery for glottic cancer involving the anterior commissure.@*Methods@#Thirty-two cases of glottic cancer involving the anterior commissure treated by transoral CO2 laser surgery between March 2009 and December 2013 were retrospectively reviewed. Among these cases, 27 were T1bM0M0, 5 were T2N0M0. All cases were followed-up for more than 3 years.@*Results@#All the 32 cases were successfully treated. Perioperative complications included injuries in the soft palate mucosa(13/32, 40.63%), loose incisors(3/32, 9.38%) and subcutaneous emphysema in the neck(2/32, 6.25%). During the follow-up period, granulation was found in all cases. Three cases had local recurrence. Two patients treated by a secondary transoral CO2 laser surgery and the other case had total laryngectomy, all three cases were followed up for 5 years without recurrence. Two cases had regional recurrence but no primary site recurrence. One patient was treated by neck dissection, and followed up for 5 years without recurrence. The other patient died of supraclavicular and mediastinal lymph node metastasis and lung metastasis 40 months after operation. The overall 5-year survival rate was 90.6%. There was no significant difference in survival rate between T1bN0M0(92.6%) and T2N0M0(80.0%) (Log Rank χ2=0.788, P=0.375). The overall 5-year local regional control rate was 84.4%. In T1bN0M0 lesions, the 5-year local regional control rate was 92.6%, which was significantly higher than that in T2N0M0 lesions(40.0%) (Log Rank χ2=9.504, P=0.002).@*Conclusion@#With appropriate surgical indication, detailed preoperative evaluation, good surgical skill, transoral CO2 laser surgery may achieve satisfactory outcome in the treatment of glottic cancer involving the anterior commissure.
ABSTRACT
Objective To comparemodified bone cement injection sleeve (front end closed,unilateral opening) and traditional straight push bone cement sleeve in percutaneous vertebral plasty (PVP) for clinical application.Methods From January 2015 to June 2016,78 patients with PVP indications of single osteoporotic vertebral compression fracture (OVCF) were randomly divided into a study group and a control group (39 patients for each group),and both groups received PVP under DSA.Intraoperative X-ray exposure dose,surgical duration,postoperative bone cement leakage,VAS score (preoperative and postoperative 3 days and 6 months),and refracture rate after half a year and postoperative bone cement distribution were compared between the two groups.Results Both groups received a follow-up for 6 to 12 months.5 patients had paravertebralleakage in the study group,while 9 patients developed paravertebralleakage and orie patient had anterior leakage in the control group.No neurologic and vascular injury occurred,no pulmonary embolism and other serious complications developed.The patients in both groups were followed up for half a year without re-fracture.The radiation dose and surgical duration in the two groups were statistically significant (P＜0.05).Bone cement injection and postoperative VAS scoresdid not differ obviously between the two groups (P＞0.05),There was no significant difference between the two groups in distribution of bone cement (P＞0.05).The bone cement leakage rate was lower in the study group than in the control group,with a statistical significance (P＜0.05).Conclusions The improvement in bone cement injection sleeve can shorten surgical duration,reduce intraoperative X-ray exposure,and decrease the rate of leakage of bone cement.It is worth popularizing clinically.
ABSTRACT
The purpose of the current study was to evaluate the anti-inflammatory activity of tetramethlpyrazine on oxazolone-induced colitis mice. Spleen mononuclear cells [SMC], lamina propria mononuclear cells [LPMC] and peripheral blood mononuclear cells [PBMC] were isolated from oxazolone-induced colitis and normal mice. The colitis cells treated by oxazolone were randomly divided into model, low dose, middle dose and high dose groups treated with 0, 0.5, 1.0 and 2.0 g/L tetramethlpyrazine, respectively. The apoptotic rate of SMC and LPMC in the oxazolone-induced group was lower than that in the normal group. Compared with model group, apoptotic rate of SMC was significantly increased in the high dose group, while the apoptotic rate of LPMC in the middle dose group was increased. Compared with SMC, LPMC and PBMC of normal group, the mRNA level of nuclear factor kappa B [NF-kB], transcription factor-activated protein-1 [AP-1] and nuclear factor of activated T cells [NF-AT] were higher in model group. Tetramethylpyrazine inhibited the increase of NF-kB, AP-1 and NF-AT mRNA induced by oxazolone. For SMC, LPMC and PBMC there was significant difference in the mRNA level of AP-1 among the three different doses of tetramethylpyrazine treated groups. However, no significant difference was observed in the mRNA levels of NF-AT and NF-kB between normal and middle groups. Tetramethylpyrazine promoted the apoptotic rate of SMC and LPMC in-vitro, and suppressed the expression of transcription factors in SMC, LPMC and PBMC isolated from oxazolone-induced colitis mice. The study provides a novel insight into the mechanism behind the effect of etramethylpyrazine on colitis

OBJECTIVE@#To explore the histopathological changes of the new trachea reconstruction with a scraped partial mucosa jejunal autograft hy microscope and transmission electron microscope.@*METHOD@#Eight canine models of extensive circumferential tracheal defects with revascularized jejuna combined with NiTi alloy mesh tube were established. Operations were performed on these dogs under general anesthesia by intravenous ketamine. A 6.5 cm length of segment of the jejunum was resected. The graft was prepared by scraping the partial mucosa with operating knife blade and dry gauze. During the resecting course, micro-vascular anastomoses were done between the mesenteric artery and the right common carotid artery,and the mesenteric vein with the right common carotid vein. The silicone intraluminal stent was placed in the lumen of the jejunal segment and was removed the fourth week after operation. A Ni-Ti alloy prothesis was placed over the jejunal segment, with the mesenteric vascular supply egressing through the longitudinal defect of the mesh tube. Then the free jejunum was used to reconstruct the tracheal defects. Biopsy were performed and recorded at the 1 at, 2nd, 3rd and 4th postoperative months. All specimens were observed by microscope and transmission electron microscope examinations.@*RESULT@#Eight dogs postoperative all survived expected time. One month after operation, the tracheointestinal snastomosis showed smooth and was covered by continuous internal lining. The mucosa of the jejunum was slightly atrophied. Two months after operation, examination of the jejunal mucosa of the autografts demonstrated obviously thinned. The lumen of the reconstructed trachea was covered by squamous epithelium entirely at 3 months postoperatively. The partial squamous epithelium has transformed ciliated columnar epithelium at 4 months postoperatively.@*CONCLUSION@#A free scraped partial jejunum reconstructed trachea can accelerated the atrophying process of mucous epithelization and promoted mucosal metaplasia of the jejunum. The reconstructed tracheal lumen has completely transformed squamous epithelium at 3 months postoperatively and partial squamous epithelium has transformed ciliated columnar epithelium at 4 months postoperatively.

Objective To investigate the effects of interleukin-10 on mice intestinal fibrosis and epithelial-mesenchymal transition(EMT),and the relation between these effects and endoplasmic reticulum stress(ERS).Methods Forty-two IL-10 knockout(IL-10-/-)mice were divided into fibrosis model group(n=18),IL-10 treatment group(n=12)and solvent control group(n =12),another 18 wild-type mice were taken as negative control group.IL-10 and 0.9％ NaCl were intraperitonealy injected in IL-10 treatment group and solvent control group respectively since 12th week,and mice were sacrificed at week 14th and 16th,and no treatment to fibrosis model group and negative control group.The injury and fibrosis in mice colon tissue were detected with HE staining and Masson collagen staining.The expressions of collagen Ⅰ,glucose-regulated protein78(GRP78),C/EBP homologous protein(CHOP)and a-smooth muscle actin(α-SMA)and E-cadherin(E-cad)at mRNA level were determined by realtime PCR.The expression of α-SMA and E-cad in mice colon tissue was examined by immunohistochemical staining.Results At 16th week,the colonic tissue injury scores(7.00±0.90,7.17±1.17)and collagen area ratio(17.78％±4.15％,18.56％±3.81％)of fibrosis model group and solvent control group significantly increased compared with negative control group(1.50±1.38 and 9.11％±2.99％)and IL-10 treatment qroup(4.33±0.82 and 12.56％±1.39％)(F=36.150,F=11.280； P=0.000).At week 12th,14th and 16th,the expressions of GRP78,α-SMA,collagen Ⅰ in fibrosis model group and solvent control group significantly increased compared with negative control group(all P＜0.05),however the expression of E-cad significantly decreased(P＜0.05).The expression of CHOP mRNA in fibrosis model group(0.95％ ±0.12％)significantly increased compared with negative control group(0.21％ ± 0.12％)at week 12th(t=5.188,P=0.000),however there was no statistical significant difference in groups at week 14th and 16th(P＞0.05).At week 14th and 16th,the expressions of GRP78,α-SMA and collagen Ⅰ(at week 14th:0.73％±0.31％,1.18％±0.11％ and 1.10％±0.49％； at week 16th:0.57％±0.16％,0.81％ ±0.50 ％ and 0.76 ％ ± 0.25 ％)in IL-10 treatment group were significantly lower than that of fibrosis model group(P＜0.05).The expression of E-cad(at week 14th:0.73％ ±0.29％ ； at week 16th:0.97％ ±0.25％)significantly increased compared with fibrosis model group(at week 14th:0.37％±0.17％； at week 16th:0.35％±0.20％)(F=6.524,P=0.003； F=17.493,P=0.000).However at week 16th,the expression of α-SMA in IL-10 treatment group was lower than that of solvent control group(1.82±0.22)％(F=9.842,P=0.000),and the expression of E-cad significantly increased than in solvent control group(0.47 ± 0.25)％(F=17.493,P =0.000).Conclusion IL-10 may have a role in inhibiting EMT and reducing intestinal fibrosis in mice,which may be related to the regulation of ERS by IL-10.
ABSTRACT
OBJECTIVE@#To explore the effective treatment regimen for osteoradionecrosis of temporal bone.@*METHOD@#Twenty-seven patients with massive osteoradionecrosis in temporal bone were included and retrospectively analyzed, in which, 15 cases received surgery and the other 12 cases adopted non-surgical treatment.@*RESULT@#In the surgery group, three cases died one year postoperatively and died of massive hemorrhage due to internal carotid blowout. One case died four years after surgery without clear cause of death, and two cases were lost to follow up. Out of the nine survivors, the follow up period ranged from four months to eight years (one was followed up eight years, one was followed up over four years, four were followed up two-three years, one was followed up over one year, one was followed up nine months, and one was followed up four months, respectively). Patients classified as the type III received best outcome, and patients of type V and IV without invasion of the internal carotid artery received good surgical effects, while patients classified as the type IV with internal carotid artery invasion presented low survival rate. Two cases in the non-surgical group died of internal carotid rupture, and the other ten cases presented with repeated infection and expansion of the osteoradionecrosis lesion.@*CONCLUSION@#The new classification criteria is helpful in diagnosis of location of lesions,and can serve as a guide for clinical therapy. Massive osteoradionecrosis in temporal bone responded unfavorably to conservative treatment, compared to that, surgery can effectively control the expansion of the lesion and markedly improve patient quality of life. Long-term follow up is necessary because of the slow development of osteoradionecrosis after surgery.

Objective To investigate the anti-fibrotic effects of curcumin in trinitrobenzene sulphonic acid (TNBS) induced intestinal fibrosis in rats and its mechanism. Methods Forty SD rats were randomly divided into model group, treatment group, control group and normal group with 10each. Except the normal group, the other three groups were given 10, 15, 20, 25 and 30 mg of TNBS enema on the 1st, 8 th, 15th, 22nd and 29th days,respectively. The rats in treatment group were intraperitonealy injected with 30 mg/kg of curcumin daily. Control group was injected with 0. 9%NaCl solution and normal group received an equal volume of 50% ethanol enema without any treatment. The damage and fibrosis of colon were detected with HE staining and Masson collagen staining, respectively. The contents of interleukin (IL) -2, tumor necrosis factor (TNF) -α, IL-4 and IL-17 in colon were measured by enzyme-link immunosorbent analysis (ELISA). The expressions of intestinal fibrosis related cytokines such as transforming growth factor (TGF) -β1, connective tissue growth factor (CTGF), Smad3, collagen Ⅰ and collagen Ⅲ mRNA were determined by FQ-PCR.Results The macroscopic and micrpscopic colonic damage scores and collagen area were significantly higher in model group (6.14 ± 1.07, 8. 42 ± 1.40 and 36. 59% ± 4.07%, respectively) and control group (6.17 ± 1.47, 8. 17 ±1.47 and 37.18 %±4.05 %, respectively) than those in normal group (2.13±0.64, 2.25±1.28 and 25.43%±5.39% ,respectively)(P＜0.05). Contents of IL2, TNF-α, IL-17, as well as expressions of intestinal fibrosis related cytokines including TGF-β1, CTGF,Smad3, collagen Ⅰ and Ⅲ mRNA were also higher in model group [(378. 25±29. 90) ng/L,(87.11±23.85) ng/L, (47.80±5.62) ng/L, 4.71%±2.71%,10.33%±6.99%,9.35%±7.32%,1.52% ± 1.11% and 3.04% ±1.33%, respectively] and control group [(410. 06 ± 64.74) ng/L,(100.41±12.59) ng/L, (41.45±2. 12) ng/L, 4. 12%±3.01%,11.46%±4.72%,10. 11%±3.80%,1. 57% ± 1. 35% and 3. 03% ± 3. 53%, respectively] in comparision with normal group [(179.74±20. 73) ng/L, (35. 47±7. 13) ng/L, (14. 48±7. 52) ng/L and 0. 90%± 1. 13%,0.53%±0.47%, 0. 62%±0. 44%, 0. 16%±0. 09% and 0. 18%±0. 10%, respectively] (P＜0.05). While in treatment group, the macroscopic (4.00 ± 1.07 ) and micrpscopic (5. 13 ± 1.46)colonic damage scores, collagen area (30.01%±7.56%), contents of IL-2 [(223.91±28.04) ng/L],TNF-α [(44.19±4. 77) ng/L] and IL-17 [(14.89±4. 31) ng/L], expressions of TGF-β1 (0.85%±0.76%), CTGF (1.56%±1.13%), Smad3 (3.62%±3.03%), collagen Ⅰ (0.40%±0.31%) and Ⅲ (0.60 % ± 1.02 % ) mRNA were much lower than those in model group and control group (P＜0.05 ), but similar to those in normal group (P＞ 0.05 ). Conclusions Curcumin can inhibit intestinal fibrosis caused by excessive "wound-healing" reaction via reducing the overexpression of cytokines in colonic mucosa and attenuating the inflammation of colon.
ABSTRACT
OBJECTIVE@#To compare the therapeutic effect between endoscopic thyroidectomy and open thyroidectomy.@*METHOD@#One hundred and nine patients were randomly divided into two groups. The first group with 52 patients were carried out endoscopic thyroidectomy; and the second group with 57 patients was carried out open thyroidectomy. Clinical features including operation time, operative blood loss, hospitalization and complications were compared between the two groups.@*RESULT@#The average operative time was (105.1 +/- 30.2) min in endoscopic group and (145.3 +/- 27.4) min in open group (P<0.01); the mean operative blood loss was (7.5 +/- 4.2) ml in endoscopic group and (48.6 +/- 18.6) ml in open group (P<0.01); the average hospitalization after operation was (4.1 +/- 1.4) days and (8.0 +/- 1.9) days (P<0.01), the complication rate was 5.8% in endoscopic group and 8.8% in open group (P<0.01).@*CONCLUSION@#Compared to the traditional open surgery, endoscopic thyroidectomy is safe and effective,with advantages in terms of the aesthetic property,the amount of bleeding and the postoperative complications.
