Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine （Part 8）： Quality Evaluation with AGREE Ⅱ and RIGHT / 中医杂志

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine （CPM） with internationally recognized tools the appraisal of guidelines for research and evaluation （AGEREE） Ⅱ and reporting items for practice guidelines in healthcare （RIGHT）， thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI， VIP， Wanfang and Sinomed were searched for CPM guidelines， as well as medlive.cn， websites of China Association of Chinese Medicine and Chinese Medical Association， and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools， and consistency tests were performed using Interclass Correlation Coefficient， and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally， 140 CPM guidelines were included， of which 51 were disease-oriented and 89 were drug-oriented， all of which were issued by China. For 51 disease-oriented CPM guidelines， the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity， and the lowest was 26.80% for application； for 89 drug-oriented CPM guidelines， the highest average score was 55.62% for scope and purpose， and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist， the highest reporting rate was 68.26% for background， and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines； the highest reporting rate was 61.31% for background， and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ （rigour of development， clarity of presentation， editorial independence）， as well as four domains of RIGHT checklist （basic information， evidence， funding and declaration and management of interests， and other areas）. ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist， and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines， thereby guiding the clinical use of CPM in a better way.

Application of Endoscopic Parathyroidectomy in the Treatment of Primary Hyperparathyroidism / 中华内分泌外科杂志

Objective:To summarize the experience and the clinical data of patients with primary hyperparathyroidism undergoing endoscopic parathyroidectomy.Methods:A total of 24 patients who underwent endoscopic parathyroidectomy for primary hyperparathyroidism in Peking Union Medical College Hospital during Feb. 2021 to May. 2022 were concluded in this study (20 cases of parathyroidectomy via axillary approach and 4 cases of parathyroidectomy via thoracic and breast approach) . The operation time, postoperative drainage, length of stay, level of parathyroid hormone and serum calcium of those patients were collected. Postoperative complications and recurrence of hyperparathyroidism were also observed.Results:The postoperative levels of serum parathyroid hormone and serum calcium were significantly reduced (over 50%) compared with preoperative level ( P<0.05) . The average operation time was (96±22) min (64-157 min) . The mean postoperative drainage volume was (47±16) ml on day 1, (46±11) ml on day 2, and (30±9) ml on day 3, respectively. The average length of postoperative hospital stay was (2.8±1.1) days (2-6 days) . In one case of parathyroidectomy via axillary approach, the operation was converted to open surgery because of the low position of lesion. Other cases completed endoscopic surgery and obtained satisfactory cosmetic results. There were no postoperative complications such as bleeding, permanent hoarseness, coughing while drinking water, or surgical site infection. The mean follow-up time was (7.4±4.2) months (1-16 months) . There was no obvious discomfort and no recurrence during follow-up. Conclusion:Endoscopic parathyroidectomy is safe and effective in the treatment of primary hyperparathyroidism, which can be used as a surgical option for patients with cosmetic requirements.

During the recovery of pancreatitis, the patient developed acute acalculous cholecystitis, as well as carbapenem-resistant Enterobacter infection and Cytomegaloviremia, and had anaphylaxis for several times after the use of antibiotics, which cannot be completely explained by drug allergy. This paper analyzes the possible causes of multiple diseases in the same patient in detail.

Preoperative diagnosis and surgical strategies of primary hyperparathyroidism / 中华内分泌外科杂志

Objective To investigate the preoperative localizaion diagnosis and surgical strategies of primary hyperparathyroidism (pHPT).Methods The clinical data of pHPT patients who underwent initial parathyroid surgery at the Peking Union Medical College Hospital from Jan.2009 to Apr.2017 were retrospectively analyzed to explore preoperative localization and surgical options.Results There were a total of 902 surgical cases included in the study with 674 women and 228 men.All had preoperative parathyroid ultrasonography (US) (sensitivity 97.18％,positive predictive value (PPV) 98.40％) and 99Tcm-sestamibi (MIBI) scan (sensitivity 94.24％,PPV 98.00％).The combination of US and MIBI scan had a sensitivity of 92.39％ and PPV of 97.37％.MIBI scan showed negative results in 51 cases.We found that male patients with cystic lesions were more likely related to negative MIBI scan (P＜0.05).Among 89 patients with negative MIBI and/or US,39 received neck CT,17 received positron emission tomography (PET)/CT,and 9 received ultrasound-guided biopsy for further localization.800 patients (88.69％) underwent minimally invasive parathyroid surgery (MIP) with anesthesia of cervical plexus block.656 patients (72.72％) had normal parathyroid hormone (PTH) level on the first post-operative day,140 patients (15.52％) had postoperative hypocalcaemia and 234 patients (25.94％) presented hypocalcaemic symptoms within 3 days after operation,which could be relieved by intravenous calcium or continuous medicine taken by mouth.During the follow-up of the 800 MIP patients,4 had recurrence and one patient was not cured.Conclusions Parathyroid US and MIBI scan are of good value in localizaion diagnosis.Neck CT or PET/CT should be used as supplementary approaches in patients with negative US and/or MIBI scan.MIP with anesthesia of cervical plexus block is simple and feasiable for pHPT cases with accurate localization.

Diagnosis and Clinical Analysis of Primary Thyroid Lymphoma / 中国医学科学院学报

Objective To summarize our experiences in the diagnosis and prognosis of different subtypes of primary thyroid lymphoma (PTL). Methods The clinical data of 27 PTL patients who were treated in our hospital from January 1998 to December 2014 were retrospectively analyzed. The pathological types of these patients included B cell lymphoma unclassifiable (BCLU) (n=5),mucosa-associated lymphiod tissue lymphoma (MALT) (n=9),diffuse large B cell lymphoma (DLBCL) (n=12),and T cell lymphoma (n=1). Results Of all these 27 cases,the most common clinical symptom was painless swelling of the neck (n=21,77.8%). Of 7 patients who had received preoperative fine needle biopsy,lymphoma was suspected in 2 cases (28.6%). Among these 7 cases,the positive rate of suspicious lymphoma was 66.7% in 3 DLBCL patients,0 in 3 MALT patients,and 0 in 1 BCLU paitent. Also,25 patients underwent intraoperative frozen pathological examination,which revealed lymphoma or suspicious lymphoma in 16 cases (64.0%); in these patients,the positive rate was 66.7% for BCLU,77.8% for MALT,58.3% for DLBCL,and 0 for T-cell lymphomas. The overall survival was (89.3±12.4) months,and the overall 5-year survival rate was 61.6%. The estimated survival in symptomatic group was 31.6 months,which was significantly shorter than that in asymptomatic group (97.9 months) (P=0.032). Other factors including age,sex,tumor size,tumor stage,international prognostic index,tracheal compression,lactate dehydrogenase,residual tumor,and pathological type showed no significant effect on survival(all P>0.05). Conclusions DLBCL has the highest fine needle biopsy positive rate,MALT has the highest frozen pathological positive rate,and intraoperative frozen pathology has more malignant results than the preoperative fine needle biopsy in the diagnosis. The accompanying lymphoma symptoms may be an adverse prognostic factor.

The clinical analysis of preventable reoperation for primary hyperparathyroidism / 中华外科杂志

Objective@#To discuss the diagnosis, preoperative imaging and surgical technique of patients who underwent reoperation for persistent hyperparathyroidism.@*Methods@#A prospective database about primary hyperparathyroidism in Department of General Surgery, Peking Union Medical College Hospital was searched for the patients who underwent reoperation for persistent hyperparathyroidism from January 2009 to December 2016. The information about the initial operation, preoperative imaging study and result of reoperations were collected and reviewed. A total of 58 patients underwent reoperation for hyperparathyroidism. Eleven of these patients were referred to this institute for reoperation after missing single parathyroid lesion in the initial parathyroidectomy. Nine patients were female, and the mean patient age at reoperation was 54.9 years.@*Results@#For this group, the accuracy of ultrasound neck scan and sestamibi scintigraphy was 10/11 in identifying diseased parathyroid gland before reoperation. Combined with enhanced CT and SPECT, all parathyroid lesions were localized before reoperations. With general anesthesia or cervical plexus block, all diseased parathyroid glands were removed in the reoperations. No signs of hyperparathyroidism appeared during follow-up.@*Conclusions@#The initial surgery for primary hyperparathyroidism should be performed in experienced center to avoid reoperations. Combining preoperative localization and cervical exploration will help to increase the success rate of reoperation.

Pancreatitis in patients with primary hyperparathyroidism / 中华内分泌外科杂志

Objective To investigate the clinical characters of pancreatitis in patients with primary hyperparathyroidism (PHPT).Methods The clinical data of patients with PHPT undergoing parathyroidectomy from Jan.2009 to May.2014 in Peking Union Medical College Hospital were retrospectively analyzed for coexistent pancreatitis.Results 571 patients received parathyroidectomy due to PHPT during this period.Thirteen patients (2.3％)with PHPT were confirmed with coexistent pancreatitis by clinical manifestation and abdominal imaging evaluation,including acute pancreatitis in 9 patients and chronic pancreatitis in 4 patients.PHPT with pancreatitis was associated with preoperative serum intact parathyroid hormone(iPTH)higher than 500 pg/ml (P=0.025)and occurrence of hypercalcemic crisis (P=0.013).The age and sex of patients,preoperative serum calcium,gallstones,urinary calculi and bone fracture were not related with pancreatitis in this group.The average follow-up period for these patients was 34(ranging from 13 to 68)months.All patients were free from hyperparathyroidism recurrence.Only one young lady with chronic pancreatitis suffered from repeated pancreatitis after surgery.Conclusions Serum iPTH higher than 500 pg/ml and occurrence of hypercalcemic crisis were possible risk factor of pancreatitis in patients with PHPT.Parathyroidectomy can help to prevent the recurrence of pancreatitis in these patients.

The treatment of papillary thyroid carcinoma located in the isthmus / 中华内分泌外科杂志

Objective To investigate the treatment for papillary thyroid carcinoma (PTC) located in the isthmus.Methods 90 patients with PTC located in the isthmus receiving surgery from May 2007 to Dec.2013 were enrolled.Patients' age,muhifocality,capsular invasion,central compartment lymph node metastasis were analyzed and compared with the results of 82 patients who had PTC within the thyroid lobe.Results In patients with PTC located in the isthmus,those with multi foci were older((49.4 ± 9.9)years,P =0.004).Patients with capsular invasion had larger tumor((1.02 ± 0.43) cm,P =0.001).Compared with PTC within the lobe,PTC located in isthmus were more likely to be multifocal (27.8％ vs 14.6％,P =0.036)and capsular invasive(42.2％ vs.19.5％,P =0.001).Central compartment lymph nodes metastasis rate was higher in patients with PTC located in isthmus but no statistical difference was found(53.3％ vs 48.8％,P =0.551).Conclusions PTC located in the isthmus tends to be more aggressive at early stage.Central compartment lymph node metastasis occursearly and can be on both sides.Most patients should receive total thyroidectomy and central compartment lymph node dissection of both sides,but there's no need to dissect lymph node beneath the recurrent laryngeal nerve on the contralateral central compartment.

Influence of STAT1 on proliferation and IFN-βsensitivity of human non-small-cell lung cancer H1299 cells / 中国病理生理杂志

AIM:To investigate the effect of signal transducer and activator of transcription 1 ( STAT 1 ) on proliferation and interferon-β(IFN-β) sensitivity of human non-small-cell lung cancer H1299 cells.METHODS:STAT1 or EGFP gene was transfected into H1299 cells by the lentiviral vectors system.The cell number was counted under a mi-croscope and cell proliferation was tested by MTT assay.In addition, the cells transfected with STAT1 and EGFP were trea-ted with IFN-βand cell viability was measured by MTT assay.The protein levels of p-STAT1, ICAM-1 and PCNA were de-tected by Western blot.RESULTS: Over-expression of STAT1 inhibited H1299 cell proliferation (P<0.05).H1299 cells transfected with STAT1 gene had a higher sensitivity to IFN-βthan the control cells transfected with EGFP ( P <0.05).Overexpression of STAT1 increased the protein level of p-STAT1, and reduced IACM-1 expression in H1299 cells. Moreover, STAT1 enhanced STAT1 phosphorylation and downregulated the expression of PCNA in H1299 cells treated with IFN-β.CONCLUSION:STAT1 inhibits the proliferation and enhances the IFN-βsensitivity of non-small-cell lung cancer H1299 cells.

Relationship between problem behavior and father-child relationship in 4-6-year-old children / 中国心理卫生杂志

Objective:To investigate the relationship between problem behaviorand father-child relationship in 4-6-year-oldchildren. Methods:Totally 102 children were recruited in a kindergarten in Beijing,with 36 aged four,36 aged five,30 aged six and 55 being boys and 47 being girls. Child Behavior Checklist (CBCL)was used to measure preschoolers'problem behaviors,and Family Relations Index (FRI)was adopted to assess children's rela-tionship with their fathers. Results:There were 41,49,and 12 children being classified as negative,neutral and posi-tive father-child relation respectively. Kruskal-Wallis Test revealed that there was no significant difference in scores of 3 CBCL subtests and 8 factors (P>0. 05 )among 4-,5-,and 6-year-old children. Children with negative father-child relationship scored higher on CBCL problem behavior subtests than those with neutral father-child relationship[30. 5 (7. 0,58. 0)vs. 16. 0 (0. 0,69. 0),P<0. 05 ]. They alsoscored higher on withdrawn behavior than children with neutralor positive father-child relationship [3. 0 (0. 0,4. 0)vs. 1. 0 (0. 0,6. 0),1. 0 (0. 0,4. 0),P<0. 05] . Mann-Whitney U Test manifested that boys scored higher in attention problem than girls (P<0. 0 1 ),but no gen-der difference was found in the other problem behaviors. Kruskal-Wallis Test showed that boys with negative father-child relationship scored higher than those with neutral father-child relationship on problem behavior subtest,anxie-ty-depression,attention problem,and internalized problem (Ps<0. 05 ). Boys with negative father-child relationship scored higher than those with neutraland positivefather-child relationship on withdrawn behavior (Ps <0. 05 ). No difference was found whether in CBCL subtests or problem behavior factors for girls with different types of father-child relationship. Conclusion:It suggests that the children with negative father-child relationship display more problem behavior and withdrawn symptoms;boys have more attention problems than girls;compared with girls, boys'problem behavior may be more closely related to therelationship with their father.
