Objective To explore the diagnosis and clinical characteristics of atypical severe pneumonia caused by Chlamydia abortus(C.abortus).Methods Clinical data of 4 patients diagnosed with atypical severe pneumonia caused by C.abortus in a hospital from January 2021 to November 2022 were collected.Clinical characteristics,dia-gnosis and treatment,and precautions of the disease were comprehensively analyzed.Results All 4 patients were male,aged 63-73 years old,with acute onset,high fever,cough and expectoration.Three patients had a history of contact with poultry,one patient had a history of contact with abortion goat.The interval between the emerging of clinical symptoms and the onset of acute respiratory failure in 4 patients was 1-6 days,and the oxygenation index(PaO2/FiO2)at admission was less than 200 mmHg,which gradually decreased with the progression of the disease,active support with a ventilator was necessary.Two patients had an increase in white blood cell count,4 had an in-crease in neutrophil percentage,3 had a mild decrease in platelet count.Among 4 patients,2,2,3 and 4 patients showed elevated levels of aspartate aminotransferase,alanine aminotransferase,creatine kinase,and serum creati-nine respectively,2 patients had mild hyponatremia,4 patients showed significant increase in C-reactive protein,procalcitonin,and interleukin-6 levels.Four patients'chest CT findings showed main involvement of single or mul-tiple lung lobes,with exudation and consolidation,and later involvement of multiple lobes of lung.The metageno-mic next-generation sequencing of bronchoalveolar lavage fluid detected the DNA sequence of C.abortus.Based on the clinical manifestations,contact history,chest CT,and metagenomic next-generation sequencing results of 4 pa-tients,the diagnosis was C.abortus.atypical severe pneumonia.After timely adjustment of the treatment of anti-in-fection regimen based on doxycycline,the patients'condition improved and were discharged.Conclusion C.abor-tus may also cause human pneumonia,which can lead to serious clinical outcome after infection.Patient had a histo-ry of animal contact should be alert to such diseases.Metagenomic next-generation sequencing can detect C.abortus.

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

OBJECTIVE: To explore incidence, risk factors and the relationship between preoperative heart failure and prognosis in elderly patients with hip fracture. METHODS: A retrospective analysis was performed on 1 569 elderly patients with hip fracture treated from January 2012 to December 2019, including 522 males and 1 047 females, aged 81.00 (75.00, 90.00) years old;896 intertrochanteric fractures and 673 femoral neck fractures. Patients were divided into heart failure and non-heart failure groups according to whether they developed heart failure before surgery, and heart failure was set as the dependent variable, with independent variables including age, gender, fracture type, comorbidities and hematological indicators, etc. Univariate analysis was performed at first, and independent variables with statistical differences were included in multivariate Logistic regression analysis. Independent risk factors for preoperative heart failure were obtained. The length of hospital stay, perioperative complications, mortality at 30 days and 1 year after surgery were compared between heart failure and non-heart failure groups. RESULTS: There were 91 patients in heart failure group, including 40 males and 51 females, aged 82.00 (79.00, 87.00) years old;55 patients with intertrochanteric fracture and 36 patients with femoral neck fracture. There were 1 478 patients in non-heart failure groups, including 482 males and 996 females, aged 81.00(75.00, 86.00) years old;841 patients with intertrochanteric fracture and 637 patients with femoral neck fracture. There were significant differences in age, sex, coronary heart disease, arrhythmia and dementia between two groups(P<0.05). Multivariate Logistic analysis of statistically significant factors showed that males(OR=1.609, P=0.032), age(OR=1.032, P=0.031), arrhythmia(OR=2.045, P=0.006), dementia (OR=2.106, P=0.014) were independent risk factor for preoperative heart failure. The 30-day and 1-year mortality rates were 9.9% and 26.4% in heart failure group and 3.6% and 13.8% in non-heart failure group, respectively;and had statistical significance between two groups (P<0.05). There were significant differences in pulmonary infection, cerebrovascular complications and cardiovascular complications between two groups (P<0.05). The duration of hospitalization in heart failure group was (16.21±10.64) d compared with that in non-heart failure group (13.26±8.00) d, and the difference was statistically significant (t=2.513, P=0.012). CONCLUSION Male, old age, arrhythmia and dementia are independent risk factors for heart failure after hip fracture in elderly patients. Patients with preoperative heart failure have a higher incidence of postoperative pulmonary infection, cerebrovascular and cardiovascular complications, higher mortality at 30 d and 1 year after surgery, and longer hospital stay.

Between August and September, 2021, this study included 605 SARS-CoV-2 natural infection cases and 589 SARS-CoV-2 breakthrough cases from Nanjing and Yangzhou, as well as 690 inactivated COVID-19 vaccine recipients from Changzhou, China. In SARS-CoV-2 natural infection cases, the age range was 19-91 years (median age: 66 year), and the medians(Q₁,Q₃) of IgG titers were 0.19 (0.06-1.31), 3.70 (0.76-69.48), 15.31 (2.59-82.16), 4.41 (0.99-31.74), 2.31 (0.75-13.83), 2.28 (0.68-9.94) and 2.80 (1.00-9.53) at one to seven weeks after SARS-CoV-2 infection, respectively. In SARS-CoV-2 breakthrough cases, the age range was 18-76 years (median age: 45 year), and the medians(Q₁,Q₃)of IgG titers were 1.93 (0.34-26.67), 38.87 (7.90-121.0), 75.09 (11.85-123.70), 21.97 (5.20-95.58), 13.97 (3.47-46.82), 9.56 (2.48-33.38) and 4.38 (1.87-11.00) at one to seven weeks after SARS-CoV-2 infection, respectively. In inactivated COVID-19 vaccine recipients, the age range was 18-87 years (median age: 47 years), and the medians(Q₁,Q₃)of IgG titers were 16.22 (15.84-33.42), 5.35 (2.96-13.23), 3.30 (2.18-6.18), 3.14 (1.16-5.70), 2.77 (1.50-4.52), 2.72 (1.76-4.36), 2.01 (1.27-3.51) and 1.94 (1.35-3.09) at one to eight months after SARS-CoV-2 infection, respectively. The results suggested that IgG antibodies increased gradually within two weeks after SARS-CoV-2 infection, then declined gradually at three to seven weeks in SARS-CoV-2 natural infection cases. In SARS-CoV-2 breakthrough cases, IgG antibodies increased rapidly within two weeks, then declined gradually at three to seven weeks after SARS-CoV-2 infection. Additionally, IgG antibodies decreased rapidly within three months, then decreased gradually and remained at a low level within three months after immunization.

OBJECTIVE: To observe the effect of navel acupuncture on bladder emptying function in patients with urinary retention after stroke based on the conventional treatment. METHODS: A total of 106 patients with urinary retention after stroke were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (53 cases, 3 cases dropped off). Patients in the control group were treated with drugs, catheterization and bladder function rehabilitation training. On the basis of the treatment in the control group, the observation group was treated with navel acupuncture, 30 min each time, once every other day, for 4 weeks. The bladder residual urine volume, spontaneous urination volume and catheterization times before and after treatment were compared between the two groups, and the clinical efficacy was evaluated. RESULTS: After treatment, in the two groups, the bladder residual urine volume and catheterization times were lower than those before treatment (P<0.01), and the spontaneous urination volume was higher than that before treatment (P<0.01); the bladder residual urine volume and catheterization times in the observation group were less than those in the control group (P<0.05, P<0.01), and the spontaneous urination volume was higher than that in the control group (P<0.01). The effective rate of the observation group was 90.0 % (45/50), which was higher than 72.0 % (36/50) in the control group (P<0.05). CONCLUSION On the basis of conventional treatment, navel acupuncture can effectively improve the bladder emptying function of patients with urinary retention after stroke.

Through consulting the ancient herbs， medical books and modern literature， this paper made textual research on the name， origin， producing area， quality evaluation， collection and processing of medicinal materials of Sang （Mori Folium， Mori Cortex， Mori Ramulus， Mori Fructus） in famous classical formulas， in order to provide a basis for the development of famous classical formulas containing medicinal materials of Sang. According to the research， Mori Folium and Mori Cortex were first used as medicines in Shengnong Bencaojing ， Mori Ramulus was first used as medicine in Jinxiaofang， and Mori Fructus was first used as medicine in Xinxiu Bencao. Before the Tang dynasty， there were Nyusang and Shansang. Since Tang dynasty， there were many sources of medicinal materials of Sang， including Baisang （Morus alba）， Jisang （M. australis）， Shansang （M. mongolica）， etc. According to textual research， the mainstream varieties were M. australis， M. alba and their cultivated varieties. In modern times， according to the relevant information and the Chinese Pharmacopoeia， M. alba is the original base. In ancient times， the origin of mulberry changed with the development of sericulture， mulberry has been widely planted since the Song dynasty. In the Ming and Qing dynasties， mulberry has been planted most in Jiangsu and Zhejiang. In modern times， they are mainly produced in Jiangsu， Zhejiang， Anhui， Hunan and other places. In recent years， due to the related policies and strategies such as "moving silkworms from east to west"， the center of silkworm breeding has gradually transferred to the west. As for the quality evaluation and harvesting and processing of mulberry medicinal materials， Most of the ancient and modern records of Mori Folium are the same. They are harvested after frost， and dried after removing impurities. The quality is better when the leaves are large and thick， yellowish green， holding prickly hands and undergoing frost. The harvesting period of Mori Cortex is slightly different in ancient and modern records. Ancient books record that it can be harvested all the year round， but in modern times， it is mostly harvested from late autumn to the next spring. The processing methods include removing soil and fibrous roots， scraping off yellow-brown rough skin， peeling off white skin and drying in the sun. The quality is better when they are white， thick， flexible， free of rough skin and full of powder. There are few records about the collection， processing and quality evaluation of Mori Ramulus and Mori Fructus in ancient Chinese herbal books. According to modern literature， Mori Ramulus is usually collected in late spring and early summer， with leaves removed， slightly dried， sliced while fresh， and dried in the sun. The best quality of Mori Ramulus is fine and tender with the yellow and white section. Mori Fructus is harvested from April to June when the fruit turns red， and dried in the sun， or slightly steamed and dried in the sun， and it is better to be big， dark purple， oily and thick. There are many processing methods of mulberry medicinal materials. Ancient books record stir frying， baking， burning and steaming of Mori Folium， in modern times， there is honey-roasted method， but most of them are used as raw products. In ancient materia medica， Mori Cortex has firing method， baking method， stir-frying method， honey-fried method， etc. In modern times， there are stir-fried and honey-fried methods， and most of them are used as raw products. Ancient books record that Mori Ramulus has cutting and frying methods， while modern ones have cutting， frying， wine-processed and bran-processed methods. Processing methods of Mori Fructus are consistent in ancient and modern times， and they are mostly dried after being cleaned or steamed. Based on the research results， it is suggested that M. alba should be selected as mulberry medicinal materials in the famous classical formulas， and appropriate medicinal parts and processing methods can be selected according to the indications of the famous classical formulas.

In this paper， through consulting relevant records in materia medica， medical and prescription books， and combining with modern literature， the name， origin， producing area， collection and processing of Gentianae Macrophyllae Radix in famous classical formulas from The Catalogue of Ancient Famous Classical Formulas （The First Batch） was systematically sorted out and textual research was carried out， in order to provide a basis for the development of the famous classical formulas containing Gentianae macrophyllae Radix. After textual research， it was found that Gentianae Macrophyllae Radix was the rectification of name in the past dynasties. In addition， there were other names such as Qinjiao， Qingua and Qinzhua. Gentiana macrophylla， G. straminea， G. dahurica and G. siphonantha were the main origin of this herb in ancient literature. Among them， G. macrophylla is the mainstream. In the Southern and Northern dynasties， G. straminea and G. macrophylla produced in northern Sichuan were recommended as the best. In the early Tang dynasty， G. macrophylla from the Liupan Mountain area at the border of Shanxi and Gansu provinces was the mainstream. During the Northern Song dynasty， G. siphonantha from Linxia and Qilian Mountain of Gansu province and G. macrophylla from eastern Shaanxi province were two new producing areas. In the Ming and Qing dynasties， the abundant base and production areas of Gentianae Macrophyllae Radix were gradually formed. In the past dynasties， harvesting was carried out in spring and autumn， and stored mainly by aeration drying or shade drying treatment. The processing methods are mainly the raw products after the net selection， cutting and drying， in addition to the frying， processing with wine and milk. G. macrophylla is recommended as the first choice for the herbal medicine involved in the famous classical formulas. Among them， wild products produced in Gansu and Shaanxi are the best， and raw products are recommended to be used. At the same time， it is suggested that G. siphonantha should be added to the subsequent edition of Chinese Pharmacopoeia as one of origins of Gentianae Macrophyllae Radix.

In this paper， the name， origin， producing area and other aspects of Menthae Haplocalycis Herba in the famous classical formulas were carried out by consulting herbal literature， medical books， prescription books in the past dynasties and related modern documents. Through the textual research， it can be seen that the name of Bohe was used as the correct name in the mainstream of the past dynasties， and there were still multiple synonyms， most of which originated from the false transmission of dialectal accent， producing area and efficacy. There are many varieties recorded in the literature of the past dynasties such as Bohe， Longnao Bohe， Hubohe and Shibohe. According to the textual research， Bohe， Longnao Bohe and Yebohe are consistent with Mentha haplocalyx， whcih is the mainstream variety. Longnao Bohe is named for its form of producing area， Shibohe is Mosla chinensis， Daye Bohe is Agastache rugosa， and Nanbohe is M. crispata. Menthae Haplocalycis Herba has been widely planted since Tang dynasty. It was mainly grown in Jiangsu， Zhejiang， Jiangxi and Sichuan in Ming and Qing dynasties， and Jiangsu is the genuine production area. Its quality is best if it has dry body， no roots， many leaves， green color and strong smell. In ancient times， the stems and leaves of Menthae Haplocalycis Herba were often picked and dried in summer and autumn， which is basically the same as the records of modern times when the stems and leaves are luxuriant in summer and autumn， or when the flowers bloom to three rounds， they are picked in sunny days and cut in different times， and then dried in the sun or in the shade， and the raw products was often used as medicine in ancient and modern times. Before the Song dynasty， Menthae Haplocalycis Herba was recorded as pungent and warm. Until the Song dynasty， it was written as “extremely cool” in Lyuchanyan Bencao. It may have been thought in the early stage that it was similar to several warm herbs， such as Perilla frutescens， Stachys japonica， Elsholtzia ciliata and M. chinensis in appearance， all of which have the function of Xinsan， so it was recorded as warm. Since the Qing dynasty， Menthae Haplocalycis Herba has been recorded as cool property in the mainstream materia medica， Menthae Haplocalycis Herba recorded as pungent and cool in the 2020 edition of Chinese Pharmacopoeia， and its effect is to dissipate wind heat， clear the head， relieve the pharynx and so on， the records of efficacy in ancient and modern times are basically the same. Based on the research results， it is suggested that raw products of M. haplocalyx should be selected when developing the famous classical formulas containing Menthae Haplocalycis Herba.

By consulting ancient herbal medicines， medical and prescription books， combined with modern documents， the textual research of Morindae Officinalis Radix has been conducted to verify the name， origin， changes in production areas， quality evaluation， harvesting， and processing methods， so as to provide reference and basis for the development and utilization of the famous classical formulas. After textual research， the production areas of Morindae Officinalis Radix has experienced great changes from north to south in history. The original plants involve 11 families， 14 genera and 21 species， and the mainstream varieties in ancient times were Damnacanthus officinarum and D. indicus， and the basis of Morindae Officinalis Radix in modern times has changed into the dry roots of Morinda officinalis produced in Guangdong province and other places. The medicinal parts of Morindae Officinalis Radix in ancient and modern times are all roots， and the quality is better if it has many beads， thick flesh， and purple color. Ancient medical books recorded that it was usually harvested in February and August， dried in the shade， and used to remove the wood core. And the modern harvesting and processing method is to dig throughout the year， first remove the fibrous roots， dry in the sun until 60%-70% dry， gently beat flatten and dry in the sun. The processing methods of the past dynasties are mainly salt-， vinegar-， wine-processed， etc. Based on the systematic research of Morindae Officinalis Radix， from the perspective of clinical experience and safety and effectiveness， it is recommended that the famous classical formulas should be developed from the mainstream variety since modern times， namely Morindae Officinalis Radix.

Objective: To investigate the clinical, cardiac imaging characteristics and prognosis of patients with primary cardiac angiosarcoma. Methods: The clinical data of 14 patients hospitalized with primary cardiac angiosarcoma from January 2001 to December 2017 in Peking Union Medical College Hospital were collected and analyzed. Metastatic cardiac angiosarcoma was not included in this study. Patients were followed up post discharge per telephone call or clinical visit. Results: Of the 14 patients, 8 were males and 6 were females, average age was 48 years. The main clinical symptoms were shortness of breath (8/14), hemoptysis (6/14), fever (5/14), chest pain (4/14) and cough (3/14). Imaging examinations showed that the tumors of 8 patients were located in the right heart and 6 in the pericardial cavity. Tumors in the right heart often infiltrate the atrial wall and cause pericardial effusion (7/8). Tumors in the pericardium were characterized by recurrent bloody pericardial effusion (6/6), prone to progressive constrictive pericarditis (3/6), pericardial fluid cytology was often negative (6/6). MRI showed heterogeneous high signal intensity (cauliflower aspect) on T2-weighted image and heterogeneous enhancement with a"sunray" aspect at the perfusion study. At the time of diagnosis, 8 patients developed lung or adrenal metastasis (8/14). The median survival was only 305 days. Conclusions: Primary cardiac angiosarcoma is a rare disease with non-specific clinical manifestation and poor prognosis. Imaging examinations may help diagnosis. The high invasiveness and the easy-to-metastasis feature of the tumor contribute to the poor prognosis of cardiac angiosarcoma.
