Objective To investigate the key technical points of microvascular decompression (MVD)for the treatment of primary glossopharyngeal neuralgia (GPN)and its efficacy. Methods From July 2011 to October 2016,18 consecutive patients with primary GPN treated with MVD at the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University were enrolled retrospectively. All patients received magnetic resonance angiography (MRA)examination before procedure. The anatomical relationship between glossopharyngeal nerve / vagus nerve and peripheral blood vessels were identified. Seventeen of them were treated via suboccipital retrosigmoid approach,one were treated via far lateral approach. None of the patients were treated with nerve root rhizotomy. Results Eighteen patients had paroxysmal severe pain in tongue,pharynx,tonsil or deep ear canal and other parts before procedure. Preoperative MRA indicated and confirmed in the surgery that the offending vessels were the trunks or their branches of the posterior inferior cerebellar artery in this group of patients. During the operation,the offending vessels were removed from the out brainstem areas of the glossopharyngeal nerves and vagus nerves under the direct vision in order to ensure that the blood vessels and nerves no longer contacted with each other. There were no complications, such as disability and death,cerebrospinal fluid leakage,and intracranial infection. All the patients were followed up after procedure;the mean follow-up period was 1-62 months. The symptom of pain disappeared completely in 17 of them. The Numberical Rating Scale (NRS)score for pain were 0. The pain in one patient was not relieved. The NRS score was 8 at discharge;it was the same as before procedure. Three patients had mild hoarseness,throat discomfort after procedure. They were relieved gradually in the follow-up period. Conclusion MVD is a safe and effective method for the treatment of GPN. Posterior inferior cerebellar artery is the most common offending artery. Preoperative imaging examination and clear decompression during the procedure are very important. The cutting off of glossopharyngeal nerves and vagus nerves needs to be handled with care.

Objective To investigate the treatment measures of having trigeminocardiac reflex (TCR) for the primary trigeminal neuralgia via microvascular decompression.Methods From January 2016 to December 2016,the clinical data and anesthesia records of 79 consecutive patients with primary trigeminal neuralgia admitted to the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University and treated the first craniotomy microvascular decompression were analyzed retrospectively.They were divided into a no TCR group (n=63) and a TCR group (n=16) according to the intraoperative anesthesia monitoring.The differences of baseline conditions,preoperative complications and pain involved the trigeminal nerve branches were compared between the two groups.The treatment measures and short-term prognosis of the patients with TCR during operation were summarized.Results (1) The proportion of hypertension in the TCR group was 31.2％ (n=5),it was higher than 7.9％ in the no TCR group (n=5).There was significant difference (χ2=6.273,P<0.05).(2) During the operation of microvascular decompression,16 patients in the TCR group had 19-time TCR.The baseline heart rate was 74±10/min before operation,and the heart rate decreased to 51±6/min at onset of TCR.The mean baseline arterial blood pressure was 102±13 mmHg,and the mean arterial blood pressure decreased to 74±8 mmHg at the onset of TCR.There was significant difference (P<0.05).(3) After the onset of TCR,the operation of was stopped,heart rate and the blood pressure recovered spontaneously (n=4).Fifteen patients were treated with medications,including using atropine (12 times,dose 0.2-0.5 mg) and ephedrine hydrochloride (3 times,dose 5-10 mg).Heart rate and blood pressure returned to the baseline level within 20 seconds or 20 seconds after administration of medications.There was no TCR-related cardiac complication or neurological deficit from after procedure to before discharge.Conclusions In microvascular decompression of primary trigeminal neuralgia,if TCR occurs,the selective use of anticholinergic agents or vasoactive agents is needed as early as possible.The risk factors for the occurrence of TCR need to be further verified.

ObjectiveTo investigate the current situation of the quality of life of aging people living in the rural areas in Hainan province. Methods253 permanent residents at age of 60 and above in Zhongyuan Town were sampled at random, and were investigated face to face at home. Results96.0% of them were independently managing their activities of daily life with 77.5% lived by themselves. In a self evaluation questionnaire on health status, 32.0% perceived good, 50.8% moderate and 17.2% bad,70.75% had history of chronic illnesse, cataract, hypertension, chronic bronchitis, bone and joint diseases and anemia appeared to occupy the previous five positions.41.0% were satisfied with the current medical condition,52.4% moderate and 6.6% un satisfied. 75.1% thought medical costs too expensive. At the degree of satisfaction to life, 20.2% were high, 63.8% moderate and 16.0% low. ConclusionsDue to the huge amount of demand on health services of the rural elderly people, it was suggested that more medical care should be provided to the rural elderly people, with emphasis on the chronic diseases, and the policy of prevention first and combining prevention with treatment should be sticked to.

Objective To verify the reliability of our previously established reverse-transcription loop-mediated isother-mal amplification ( RT-LAMP) method for the detection of sentinel lymph nodes metastasis in breast cancer patients .Meth-ods Sentinel lymph nodes of breast cancer patients were analyzed by RT-LAMP and FDA-approved GeneSearch methods respectively, and the consistency of the two methods was assessed with a kappa concordance test.Results One hundred and thirty-four cases of sentinel lymph node samples were collected from seven hospitals in Beijing .Using the GeneSearch assay as the gold standard, the sensitivity, specificity and consistentcy of RT-LAMP were 96.2%(25/26),96.3%(104/108) and 96.3%(129/134), respectively.Statistical analysis showed that the two methods were consistent (Kappa=0.8857, P<0.001).Conclusion RT-LAMP is highly consistent with GeneSearch ,efficient,simple and inexpensive, promising a good prospect of application to intra-operative detection of sentinel lymph nodes metastasis for breast cancer patients.

Objective To preliminarily discuss the safety and efficacy of microvascular decompression for patients with trigeminal neuralgia caused by vertebrobasilar dolichoectasia (VBD).Methods From January 2013 to August 2016,16 patients with trigeminal neuralgia caused by vertebrobasilar dolichoectasia admitted to the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University were analyzed retrospectively.All patients received preoperative magnetic resonance angiography examination.The anatomical relationship between the trigeminal nerves and the peripheral vessels was identified.Microvascular decompression was conducted via suboccipital retrosigmoid approach.They were followed up for 12-52 months after procedure.The trigeminal neuralgia score standard of Barrow Neurological Institute was used to evaluate the degree of pain of the patients before procedure,after procedure,and during the follow-up period.Results Of the 16 patients,the pain disappeared immediately in 15 after procedure,and the pain was not obviously relieved in 1 case after procedure,and the pain disappeared gradually at 6 months after procedure.One patient had hearing loss after operation compared with pre-operation.The follow-up time ranged from 12 months to 52 months.Three patients had recurrent pain at 6,12,and 36 months,respectively after procedure.Conclusion Microvascular decompression treatment of trigeminal neuralgia caused by VBD has better safety and surgical efficacy,but there was a certain pain recurrence rate,which needed further research.

Objective To analyze clinicopathological characteristics and the potential risk-related factors of female breast hyperplasia in different age groups.Method From Jan 2015 to Dec 2016,patients diagnosed with breast hyperplasia in 12 hospitals were evaluated.All patients completed the self-designed questionnaires on women'health,including basic demographic information,clinic examination information,radiologic information and pathologic results.The patients were divided into a young group (＜ 45 years old) and an elderly group (from 45 to 75 years old).Results There were 3 684 cases of breast hyperplasia,including 2 291 cases in young group and 1 393 cases in elder group,respectively Clinically breast pain type were most commonly observed in both young and older groups (50.3％ vs.42.7％,P ＜ 0.001).While pathological research based on biopsy showed that breast adenopathy were the most common changes in both groups (67.9％ vs.61.7％,P ＜0.001).More breast cancer cases were identified in elder group than that in young group,especially in clinically lump type patients (9.4％ vs.4.2％,P ＜ 0.001).Compared with elder group,patients in young group have different distribution characteristics regarding to fertility factors,lifestyle factors and psychology scale including anxiety and depression.Conclusion Distributions of clinicopathological characteristics and risk factors of female breast hyperplasia differ across different age groups.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
