Objective To investigate the clinical utility of keyhole craniotomy for Cholesteatmas in the cerebello-pontine angle region presenting as Trigeminal neuralgia by using keyhole craniotomy. Methods Clinical data of 35 pa-tients with Cholesteatmas in the cerebellopontine angle region presenting as Trigeminal neuralgia was analyzed retrospec-tively. All patients received suboccipital retrosigmoid keyhole craniotomy. Thirty cases who received conventional craniot-omy group were served as control group. A comparative analysis was conducted to assess the difference between these two groups in microsurgical methods, effects and complications. Results All patients were confirmed with MR diagnosis. In keyhole group, all patients had no pain symptoms of trigeminal neuralgia after surgical operation. The symptoms disap-peared immediately in 33 cases and gradually disappeared in 2 cases within one month following keyhole craniotomy. The tumors were totally removed in 25 cases and almost completely in 10 cases. The surgical duration was shorten in key-hole group than in conventional group (126±48 vs. 216±66 min;t=2.536, P<0.05). The amount of bleeding was smaller in keyhole group than in conventional group (91.3±52.2 vs. 186.3±65.4 mL;t=2.163, P<0.05). Postoperative neurologi-cal function was assessed in House-Brackmann. In keyhole group, there were 32 cases in class Ⅰ and 3 in grade Ⅱ. Two patients had hearing loss which was improved gradually in three months. In conventional group, there were 25 cases in class Ⅰ and 5 in grade Ⅱ (χ2=4.158, P<0.05). Postoperative hearing evaluation (AAO-HNS) revealed that there were 33 cases in grade A , and 2 in grade B in the keyhole group, whereas there were 27 cases in grade A and 3 in grade B in the conventional group(χ2=5.167, P<0.05). There were no relapse of tumors and death during 3 month to 5 years follow-up. Conclusions The suboccipital retrosigmoid keyhole craniotomy is a valid choice for Cholesteatmas in the cerebellopontine angle region presenting as Trigeminal neuralgia.

Objective To investigate the clinical characteristics of 16 patients with connective tissue diseases associated interstitial lung disease(CTD-ILD)complicated with lung cancer,and to improve the cognition of the disease.Methods Clinical data of 16 patients diagnosed as CTD-ILD associated with lung cancer,who were admitted to our center,were retrospectively analyzed,including general conditions,clinical characteristics,auxiliary examinations,pathological classification of lung cancer,TNM type,treatment and clinical outcome.Results Among the 16 CTD-ILD patients with lung cancer,there were 12 males and 4 females.The mean age at diagnosis of CTD-ILD was(64.7±9.2)years,and the mean age at diagnosis of lung cancer was(66.6±8.7)years.Lung occupying space on imaging(62.5%)was the most common initial symptom in lung cancer patients,followed by cough and phlegm(12.5%)and chest pain(12.5%).Of patients with lung cancer,adenocarcinoma(8 cases,50.0%)was the most common pathological type,followed by small cell lung cancer(4 cases,25.0%).The diagnosis time of CTD-ILD was earlier than that of lung cancer in 8 cases(50.0%),with a median time of 36.0(11.3,57.0)months,followed by 7 cases(43.8%)of CTD-ILD diagnosed with lung cancer at the same time.The diagnosis time of lung cancer was earlier than that of CTD-ILD in 1 case(6.3%).The most common TNM stage for lung cancer was stage Ⅳ(9 cases,56.25%).Sixteen patients were followed up from 1 to 64 months,with a median of 8.5(1.5,14.3)months.Eleven patients(68.8%)died,including 8 patients(72.7%)died of infection and 3 patients(27.3%)died of end-stage lung cancer.Conclusion For CTD-ILD patients,close follow-up and regular imaging monitoring are necessary to help early detection of lung cancer and improve prognosis.

ObjectiveTo explore the clinical efficacy of Huanglian Jiedutang as an adjunctive treatment for acute cerebral infarction complicated with gastric motility disorder. MethodSixty patients with acute cerebral infarction complicated with gastric motility disorder with fire toxin syndrome were randomly divided into a western medicine control group （control group） and a traditional Chinese medicine （TCM） combined treatment group （observation group）， with 30 cases in each group. The control group received basic treatment for cerebral infarction and relevant western medical symptomatic treatment based on the patients' gastrointestinal symptoms. The observation group received Huanglian Jiedutang in addition to the treatment provided to the control group. The treatment course was 7 days. Neurological deficit scores and gastrointestinal dysfunction scores were assessed in both groups before treatment and on the 4^th and 7^th days of treatment. Gastrointestinal electrographic parameters， serum citrulline （CIT）， and motilin （MTL） levels were measured in both groups before treatment and on the 7^th day of treatment. Clinical efficacy was compared between the two groups. ResultCompared with the baseline in both groups， the neurological deficit scores and gastrointestinal dysfunction scores were significantly reduced on the 4th and 7^th days of treatment （P<0.05）. The reductions in these scores were more significant on the 7^th day compared with those on the 4^th day of treatment （P<0.05）. On the 4^th and 7^th days of treatment， the observation group showed a significantly greater reduction in neurological deficit scores and gastrointestinal dysfunction scores compared with the control group （P<0.05）. On the 7th day of treatment， compared with the baseline， both groups showed a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. On the 7th day of treatment， compared with the control group， the observation group had a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. After 7 days of treatment， the total effective rate in the observation group was 90.00% （27/30）， higher than 76.67% （23/30） in the control group， but the difference was not statistically significant. ConclusionAdjunctive treatment with Huanglian Jiedutang can effectively improve the symptoms of neurological function impairment and gastrointestinal dysfunction in patients with acute cerebral infarction complicated with gastric motility disorder， increase gastric antral and gastric body electric wave amplitudes， improve gastric motility disorder， and increase serum CIT and MTL levels， thereby improving the imbalanced secretion function of the gastrointestinal tract.
