Objective To discuss clinical characteristics of a family with Andersen-Tawil syndrome, test and analyze the mutation of their pathogenic gene, and to discover the dependency of genotype and phenotype by searching every reported Andersen-Tawil syndrome patient in all accessible literature worldwide.Methods In December 2nd,2016,two patients in the Department of Neurology,the First Hospital of Shanxi Medical University, received medical history data collection and relevant examinations.PCR and DNA sequencing were applied to detect ion channel diseases related genes such as SCN4A, CACNA1S, KCNJ2, KCNE3, KCNE4, KCNJ18, KCNJ5.Random selection of 200 healthy volunteers from Shanxi Medical University served as normal controls.Andersen-Tawil syndrome cases,which are accorded with statistical criteria in published literature, were collected.Their genotype and phenotype were analyzed and summarized.Results Clinical manifestation of the pre-confirmed patient and his father was accorded with diagnostic criteria of Andersen-Tawil syndrome.Prominent characteristics included ventricular arrhythmia, periodic paralysis, and dysmorphic features.The two patients had renal tubular acidosis.One of these two patients also had increased level of renin-angiotensin-aldosterone.New mutation Q164R in the KCNJ2 gene was found in these two patients.There was no report in any literature or any database that we could find about this gene mutation at present.The mutation was not found among other healthy family members and 200 healthy controls.In this study,we referenced 55 samples of Andersen-Tawil syndrome in 12 articles,in which 54 samples are KCNJ2 gene mutation,one is KCNJ5 gene mutation.We concluded a negative correlation between the onset age of periodic paralysis and the onset age of cardiac symptoms after a statistical analysis of these 54 patients with KCNJ2 gene mutation(rs=-0.698 1,P=0.005 5).The incidence of cardiac symptoms in patients of Andersen-Tawil syndrome with periodic paralysis was reduced(33.33%(14/42)vs 9/11, χ2=6.485,P=0.011).Men(96.00%(24/25))were found more likely to have periodic paralysis than women(65.52%(19/29); χ2=7.691,P=0.006).Women (64.29%(18/28))were found more likely to have cardiac symptoms than men(20.00%(5/25); χ2=10.545,P=0.001).Conclusions New mutation Q164R in the KCNJ2 gene is the cause of Andersen-Tawil syndrome,which could cause renal tubular acidosis.We speculate that the gene may play a role in the way of potassium regulating aldosterone.For women with the KCNJ2 gene mutation and the late-onset of periodic paralysis,it is important to take drug or manual intervention as early as possible to prevent the occurrence of cardiogenic adverse events.

Objective Through description of the clinical,electrophysiological,pathological and gene sequencing characteristics of a family diagnosed as paramyotonia congenita and hypokalemic periodic paralysis to broaden the understanding of skeletal muscle channel disease and provide the reference for clinical diagnosis.Methods The clinical manifestation,electromyography,muscle pathology and gene sequencing of a family diagnosed as paramyotonia congenita and hypokalemic periodic paralysis in the First Hospital of Shanxi Medical University in October 2017 were collected.Results The proband represented myotonia and episodic muscle weakness,and the manifestations of different patients of the family were varied,including myotonia,episodic muscle weakness or myotonia and episodic muscle weakness.The electromyography of the proband showed myotonic potential,and the compound muscle action potential decreased by 36％ in 40 minutes after exercise in the long exercise test in cold environment (11 ℃).The gene sequencing showed α-subunit type Ⅳ of voltage gated sodium channel (SCN4A) gene p.R1448H mutation.Conclusions The proband presented with paramyotonia congenita and hypokalemic periodic paralysis.Family clinical manifestations suggested phenotypic heterogeneity.The long exercise text in cold environment (11 ℃) confirmed the diagnosis of the proband as paramyotonia congenita and hypokalemic periodic paralysis.Family gene sequencing showed that the mutation of p.R1448H in SCN4A gene was the pathogenic gene mutation site of paramyotonia congenita and hypokalemic periodic paralysis.

Objective:To describe the clinical features of a patient of anti-neurofascin 186 (NF186) antibody associated acute immune sensory polyradiculopathy (AISP), and enhance understanding of AISP/chronic immune sensory polyradiculopathy (CISP).Methods:The clinical characteristics, diagnosis and treatment of a domestic AISP patient with NF186 antibody positive admitted to the First Hospital of Shanxi Medical University in December 2021 were summarized, and the previously reported cases of AISP/CISP were systematically reviewed.Results:The patient was a 62-year-old male with acute onset. The clinical manifestations included severe sensory ataxia, increased protein in cerebrospinal fluid, no response to stimulation of the central segment of somatosensory evoked potentials (SEP), normal sensory and motor nerve conduction, and positive serum anti-NF186 antibody (1∶32). After glucocorticoid treatment, the clinical symptoms and SEP were significantly improved. The drug was stopped for 2 months, and there was no recurrence. There were 23 cases of AISP and CISP with complete data reported in the literature (including this patient). The age of onset was (54.7±17.7) years, and the ratio of male to female was 1.88. Three patients with acute onset were classified as AISP. A total of 95.7% (22/23) of patients showed sensory ataxia without limb weakness, 95.0% (19/20) of patients showed prolonged cortical potential latency or even no response, and 95.5% (21/22) of patients showed increased cerebrospinal fluid protein in varying degrees, and nerve root thickening or abnormal enhancement was not common. All 10 patients receiving immunotherapy responded to corticosteroids or intravenous immune globulin. Only 6 AISP/CISP articles reported screening for anti-ganglioside antibodies or Ranvier′s node-paranodal region-related antibodies, and no positive NF186 antibodies were reported. All the 3 patients with AISP had some characteristics of CISP/chronic inflammatory demyelinating polyradiculoneuropathy, and there was no significant difference between AISP and CISP patients in clinical features except the mode of onset.Conclusions:NF186 antibody could cause AISP, which presents as acute onset sensory ataxia. AISP is responsive to glucocorticoid therapy. Except for the mode of onset, AISP and CISP are difficult to distinguish from clinical, electrophysiological, pathological aspects and pathogenic antibodies, so they may be two different manifestations of the same disease.

Objective:To summarize the clinical characteristics of patients with Guillain-Barré syndrome (GBS) complicated with optic neuritis (ON).Methods:The clinical data of a patient with GBS complicated with ON, who admitted to the Department of Neurology, the First Hospital of Shanxi Medical University in December 2021, were collected, including demographic characteristics, clinical symptoms and signs, laboratory and electrophysiological data, and results of fundus color films. The patients with GBS complicated with ON reported in the literature were also reviewed.Results:A 40-year-old female patient with GBS was diagnosed by the results of electromyography and cerebrospinal fluid tests combining with the history and signs, who was treated with intravenous immunoglobulin on the 3rd day after onset. On the 8th day, her muscle strength improved significantly. However, on the 12th day, the visual field darkened, and on the 19th day, the vision decreased significantly (oculus dexter visual acuity 0.2, oculus sinister visual acuity 0.1 +1) with bilateral papilloedema, a relative afferent pupillary defect and delayed P100 response of the visual evoked potential. Obvious abnormality was not noted in optic nerve magnetic resonance imaging. Thus ON was diagnosed and treated with pulse methylprednisolone therapy. After 8 days of treatment, the visual acuity was completely recovered and there was no abnormality in the ocular fundus. A total of 28 cases of GBS complicated with ON (including the present patient) were reported in the literature. The age of onset was mostly 20-60 years, and there was no gender preference. Mycoplasma pneumoniae was the most common premorbid pathogen and was identified in 7 of the 10 cases in which the causative agent was described. ON usually involved both sides, and 21 of 28 patients had bilateral optic nerves involved. GBS preceded ON or both occurred simultaneously in the majority of patients; GBS preceded ON in 14 of 28 patients, and both occurred simultaneously in 10 of 28 patients. All patients responded well to immunotherapy, and vision was completely recovered in 20 patients. Conclusions:GBS complicated with ON is rare. Attention should be paid to the loss of vision in patients with GBS. Relevant examinations should be completed as soon as possible and immunotherapy should be given.

Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disease, characterized by eosinophilic transparent inclusions in the central and peripheral nervous systems, and internal organs. NIID clinical characteristics are varied, including cognitive impairment, muscle weakness, episodic symptoms, movement disorders and autonomic dysfunction. This article reports a patient with NIID who manifested with episodes of aphasia, dysgraphia and dyslexia without fever, headache, nausea and vomiting confirmed by genetic testing. The patient was a 62-year-old female with acute onset who was diagnosed with transient ischemic attack. This article aims to improve the knowledge of NIID with stroke-like onset by this case presentation and avoid misdiagnosis.

In this paper， by consulting the historical herbs and medical classics coupled with related literature in modern research， the historical edition of Chinese Pharmacopoeia and local chronicles of traditional Chinese medicine （TCM） along with the ancient historical evolution of the processing methods of Pinelliae Rhizoma origin as well as the related processing methods of Pinelliae Rhizoma origin from 1959 to 2020 were systematically collated and summarized. It was found that the main processing methods of Pinelliae Rhizoma origin were peeling， decoction washing， lime wrapping and sun-drying. However， stacking， peeling， sun-drying or oven-drying are the primary methods in modern local chronicles of TCM. Meanwhile， washing， peeling， removing fibrous roots and sun-drying are the main methods in Chinese Pharmacopoeia. In addition， there were some changes in the quality evaluation of Pinelliae Rhizoma in different historical periods. Round and white were the best in the quality evaluation of Pinelliae Rhizoma in ancient times， while the evaluation indexes were further refined to size， color， texture， powder property， purity and evenness in modern herbal works. In modern studies， the quality of Pinelliae Rhizoma was mostly evaluated by the chemical components such as alkaloids， total organic acids， polysaccharides， nucleosides， fingerprint and pharmacodynamics. At present， the purification and drying stages of Pinelliae Rhizoma are in the transitional stage between the traditional manual peeling and natural drying methods as well as the modern mechanized and large-scale production. Therefore， a reasonable and feasible modern processing methods and guiding standards of Pinelliae Rhizoma are developed urgently to normalize the processing of Pinelliae Rhizoma and ensure the quality of medicinal materials.

Objective:To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China.Methods:This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed.Results:Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn′t be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%.Conclusions:More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
