Application of multiplex PCR capillary electrophoresis and analysis of distribution characteristics of HPV infection subtypes / 中华预防医学杂志

Objective: To analyze the characteristics of human papillomavirus (HPV) infection and the distribution of HPV subtypes in Shijiazhuang, Hebei Province, and to explore the application evaluation of multiple PCR capillary electrophoresis fragment analysis for HPV typing test. Methods: A population-based cross-sectional study was conducted among 434 women (age range 17 to 74 years old, 260 patients and 174 physical examinations) included from May to August 2022 in Hebei General Hospital. HPV typing was detected by multiple PCR-capillary electrophoresis fragment analysis. Using the multiple fluorescence quantitative PCR kit as a reference, Chi-square test was used to analyze the diagnostic effect of multiple PCR-capillary electrophoresis fragment analysis, and the consistency was analyzed by Kappa value. Results: The total HPV infection rate was 45.85%(199/434), including 35.48% (154/434) of high-risk HPV (HR-HPV), 3.92% (17/434) of low-risk HPV (LR-HPV), 6.45% (28/434) of HR-HPV and LR-HPV mixed infection, 27.88% (121/434) of single type HPV and 17.97% (78/434) of multi type HPV. HPV52 (9.68%, 42/434), HPV16 (6.91%, 30/434), and HPV58 (6.91%, 30/434) are common HPV subtypes. The positive rate of physical examination was 45.40% (79/174), which was slightly lower than that of patients 46.15% (120/260), there was no significant difference (χ2=0.024,P>0.05). The highest infection rate in the 17-30 age group was 54.76% (46/84), and there was no statistical difference among the age groups(χ2=4.123,P>0.05). The sensitivity and specificity of multiplex PCR capillary electrophoresis fragment analysis were 92.96% and 94.04%, respectively, and Kappa value was 0.870, with the multiplex fluorescent quantitative PCR as the reference. Conclusion: HPV infection may appear younger, and the positive rate of HR-HPV infection is the highest, with HPV52, 16, 58 as the main infection subtypes. The detection results of multiplex PCR capillary electrophoresis fragment analysis method are highly consistent with those of multiplex fluorescent quantitative PCR method, which is suitable for HPV DNA typing.

Pompe disease, also known as glycogen storage disease type Ⅱ, is a rare autosomal recessive disease. With the application of enzyme replacement therapy, more and more patients with Pompe disease can survive to adulthood, and nervous system-related clinical manifestations gradually emerge. Nervous system involvement seriously affects the quality of life of patients with Pompe disease, and a systematic understanding of the clinical manifestations, imaging features and pathological changes of nervous system injury in Pompe disease is of great significance for the early identification and intervention of Pompe disease. This article reviews the research progress of neurological damage in Pompe disease.

Herbal-moxa plaster for diarrhea type irritable bowel syndrome of spleen and kidney yang deficiency: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.

Safety of early surgery for geriatric hip fracture patients taking clopidogrel: a retrospective case-control study of 120 patients in China / 中华医学杂志(英文版)

BACKGROUND@#Geriatric hip fracture patients receiving clopidogrel are a surgical challenge. In China, most of these patients undergo delayed surgical treatment after clopidogrel withdrawal for at least 5 to 7 days. However, delayed surgery is associated with increased complications and mortality in the older adults. This retrospective paralleled comparison study investigated the safety of early surgery for geriatric hip fracture patients within 5 days of clopidogrel withdrawal.@*METHODS@#Acute hip fracture patients (≥65 years) who were hospitalized in the orthogeriatric co-management ward of Beijing Jishuitan Hospital between November 2016 and April 2018 were retrospectively reviewed. Sixty patients taking clopidogrel before injury and discontinued  0.050). The percentages of patients with coronary heart disease (61.7% vs. 18.3%; P  0.050). There was no significant difference in perioperative complications, and 30-day and 1-year mortality rates between the groups.@*CONCLUSIONS@#Early hip fracture surgery is safe for elderly patients within 5 days of clopidogrel withdrawal, without increased perioperative blood loss, transfusion requirement, complications, and mortality compared with patients not taking antiplatelet drugs.

Tumor location and lateral lymph node metastasis in papillary thyroid microcarcinoma / 中国实用外科杂志

OBJECTIVE: To evaluate tumor location as a factor predicting lateral lymph node metastasis(LLNM) and to assess the accuracy of ultrasonography(US) in the diagnosis of LLNM.METHODS: The clinicopathological data of 134 patients with thyroid microcarcinoma admitted between January 2014 and December 2015 in Tianjin Medical University Cancer Hospital were collected,and the relationship between the location of cancer foci and lateral cervical lymph node metastasis was analyzed according to the ultrasonic localization and grouping.RESULTS: The incidence rates of lymph node metastasis in levels Ⅱ,Ⅲ,Ⅳ,Ⅴ were 30.6, 50.7, 57.5 and 11.3%, respectively. Tumors located in the superior/middle were prone to metastasize to the lateral lymph nodes than those located in the inferior portion(89.7% vs. 75.7%,P=0.038). Cases with exterior locations were more likely to have lateral cervical lymph node metastasis compared with those cases with interior, respectively(93.7% vs.81.4%,P=0.049). The sensitivity values for US for the prediction of LLNM in levels Ⅱ,Ⅲ,Ⅳ,Ⅴ were 43.9%, 85.3%, 85.7% and 14.3%, and the corresponding specificity values were 91.4%, 57.6%, 35.1% and 99.1%. The ultrasonographic prediction of lymph node metastasis in Ⅲ and Ⅳ was highly sensitive,and the specificity in Ⅱ and Ⅴ was high.CONCLUSION: The localization of primary carcinoma is correlated with lateral lymph node metastasis in papillary thyroid microcarcinoma,and ultrasound could provide a basis for clinical determination of the dissection range of lateral lymph node.

Clinical and pathological analysis of malignant carotid body tumor / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To summarize the clinical, pathological and prognosis character of malignant carotid body tumor and explore its methods of diagnosis and treatment.</p><p><b>METHODS</b>The data of clinic, pathology, treatment and follow-up of nine patients with malignant carotid body tumor in Tianjin Cancer Hospital from February 1982 to June 2006 were analyzed retrospectively.</p><p><b>RESULTS</b>Four Male and five female cases were included, their average history was 6.5 years. Shamblin classification: one case was type II, eight cases were type III. All the patients were underwent ultrasonic inspection, four digital subtraction arteriography (DSA) and three magnetic resonance angiography (MRA). Seven cases were diagnosed as carotid body tumor. Five cases underwent Matas test training course. All the patients were performed wide excision of tumor and surrounding tissue. Three carotids were occludes, one of them reconstructed with vascular prosthesis, two were resected. There were no perioperative hemiplegias or deaths. Before operation, one case had atrophy of left side of tongue and fixed left vocal card; two cases had Horner syndrome. After operation, eight cases had 13 cranial nerve deficits, they were: two cerchnus, four glossal deviation, three Horner syndrome and one drop of oral corner, one choking cough. Pathologic diagnosis included nine malignant carotid body tumors, two with capsule, seven without capsule, one cervical and one lung metastasis. Two of them underwent radiotherapy. The median follow-up was 6 years (range: 6 months-14 years). Six patients survived. Two cases died, one died of cervical recurrence, the other of lung cancer. One case was lost.</p><p><b>CONCLUSIONS</b>Malignant carotid body tumor is rare in clinic, and often invade the carotid and cranial nerve, the diagnosis of malignant tumor should base on occurring extensive invasion of adjacent organs and metastasis; Wide surgical excision should be selected early, radiotherapy is effective, the effect of chemotherapy is uncertainty.</p>
