Diabetic retinopathy（DR）， as one of the most common and serious microvascular complications of diabetes mellitus， seriously threatens human health， and belongs to "Xiaoke eye diseases" in traditional Chinese medicine（TCM）， which has been richly experienced by medical practitioners through the ages， but is mostly recorded in a piecemeal manner and has not been systematically researched. This disease is featured by long course and repeated attack， and is refractory， which belongs to the research category of "persistent illness entering collaterals". Systematic establishment of TCM collateral disease theory for guiding prevention and treatment of DR has important clinical value. On the basis of close correlation between tertiary collaterals at the terminal of collaterals and capillaries and microcirculation， the concept of "tertiary collaterals-microvascular" is proposed. It is pointed out that DR falls within the scope of "tertiary collaterals-microvascular" diseases， and presents four types of micro-pathological characteristics， including stasis， insufficiency， growth and bleeding of tertiary collaterals. It is concluded that "deficiency of both Qi and Yin" is the basic pathogenesis of DR， and "blood stasis and collateral obstruction" is the important pathogenesis and key factor. Thus， the treatment method of "dispersing blood stasis， dredging collateral， tonifying Qi and Yin， stopping hemorrhage and improving eyesight" is determined， and the formula of Tongluo Mingmu capsules is developed. The article tightly focuses on the pathological changes such as stasis， growth， insufficiency and bleeding of collaterals， addresses both symptoms and root causes， and plays a synergistic role of both dispersing stasis and stopping bleeding. In this way， it can realize the purpose of tonifying Qi and Yin to replenish the essence， dispersing stasis and dredging collaterals to meet the requirement， as well as stopping hemorrhage and improving eyesight to deal with changes. Fundamental researches demonstrate that Tongluo Mingmu capsules has synergy effects of protecting both retinal capillaries and retinal cells. Phase-Ⅲ clinical trial of new drug has proven definite clinical efficacy and good safety， which provides a new drug choice for enhancing clinical effect of DR， and further supports the scientific value of Luobing theory in preventing and treating DR and other clinically significant diseases.

This paper introduces Professor Huang Huang's clinical experience in treating depression with modified classical pre-scriptions of Zhongjing.Professor Huang Huang inherited and summarized Zhongjing's academic thoughts on treating emotional disea-ses,and formulated Jieyu Chufan Recipe by combining Banxia Houpu Decoction with Zhizi Houpu Decoction.He believes that depres-sion is characterized by qi stagnation and phlegm obstruction,as well as internal disturbance of stagnation fire,and formulated a treat-ment method of clearing heat and eliminating restlessness,relieving depression and resolving phlegm.Professor Huang Huang uses Jieyu Chufan Recipe as the basic prescription,and combines relevant classical prescriptions with modifications to treat depression ac-cording to different constitutions and syndromes of patients,achieving satisfactory clinical results.

Along with intensification of social and life pressures as well as the interference from various psychological stresses， the number of people suffering from insomnia is constantly increasing， and resistance and addiction of western medicine treatment have received much attention. Safe， effective and characteristic therapeutic drug are urgently needed in clinical practices. Chinese eight-word principle of health preservation via dredging collaterals integrates health-preservation quintessence of traditional major schools of Confucianism， Taoism， Buddhism and medicine， and becomes a new theory guiding health preservation in traditional Chinese medicine. The pathogenic characteristics of "deficiency of kidney-essence， insufficiency of heart blood and loss of spirit and consciousness" as well as the therapeutic methods of "tonifying the kidney， invigorating the brain， nourishing the heart and tranquilizing" were proposed on the basis of "conserving strength" and "calming" theory included in Chinese eight-word principle of health preservation via dredging collaterals and in combination with the opinions of "primordial spirit in brain" and "consciousness spirit in heart" described by recent medical doctor ZHANG Xichun in Intergrating Chinese and Western Medicine. The development of innovative Chinese medicine Yishen Yangxin Anshen tablets reflects theoretical innovation， original formula， outstanding pharmacological characteristics and definite clinical effect， and proves scientific value of Chinese eight-word principle of health preservation via dredging collaterals.

Except the control group, mice in other groups were intraperitoneally injected with myocardial myosin heavy chain peptide (5 mg • kg

Objective: To investigate the cytomorphological and immunocytochemical features of tumor cells in the ascites of ovarian plasmacytoma (SOC). Methods: Specimens of serous cavity effusions were collected from 61 tumor patients admitted to the Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2015 to July 2021, including ascites from 32 SOC, 10 gastrointestinal adenocarcinomas, 5 pancreatic ductal adenocarcinomas, 6 lung adenocarcinomas, 4 benign mesothelial hyperplasia and 1 malignant mesothelioma patients, pleural effusions from 2 malignant mesothelioma patients and pericardial effusion from 1 malignant mesothelioma. Serous cavity effusion samples of all patients were collected, conventional smears were made through centrifugation, and cell paraffin blocks were made through centrifugation of remaining effusion samples. Conventional HE staining and immunocytochemical staining were applied to observe and summarize cytomorphological characteristics and immunocytochemical characteristics. The levels of serum tumor markers carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) were detected. Results: Of the 32 SOC patients, 5 had low-grade serous ovarian carcinoma (LGSOC) and 27 had high-grade serous ovarian carcinoma (HGSOC). 29 (90.6%) SOC patients had elevated serum CA125, but the difference was not statistically significant between them and patients with non-ovarian primary lesions included in the study (P>0.05); The serum CEA was positive in 9 patients with gastrointestinal adenocarcinoma and 5 patients with lung adenocarcinoma, and the positive rate was higher than that in SOC patients (P<0.001); The serum CA19-9 was positive in 5 patients with gastrointestinal adenocarcinoma and 5 patients with pancreatic ductal adenocarcinoma, and the positive rate was higher than that in SOC patients (P<0.05). The serum CA125, CEA and CA19-9 were within the normal range in 4 patients with benign mesothelial hyperplasia. LGSOC tumor cells were less heterogeneous and aggregated into small clusters or papillary pattern, and psammoma bodies could be observed in some LGSOC cases. The background cells were fewer and lymphocytes were predominant; the papillary structure was more obvious after making cell wax blocks. HGSOC tumor cells were highly heterogeneous, with significantly enlarged nuclei and varying sizes, which could be more than 3-fold different, and nucleoli and nuclear schizophrenia could be observed in some cases; tumor cells were mostly clustered into nested clusters, papillae and prune shapes; there were more background cells, mainly histiocytes. Immunocytochemical staining showed that AE1/AE3, CK7, PAX-8, CA125, and WT1 were diffusely positively expressed in 32 SOC cases. P53 was focally positive in all 5 LGSOCs, diffusely positive in 23 HGSOCs, and negative in the other 4 HGSOCs. Most of adenocarcinomas of the gastrointestinal tract and lung had a history of surgery, and tumor cells of pancreatic ductal adenocarcinoma tend to form small cell nests. Immunocytochemistry can assist in the differential diagnosis of mesothelial-derived lesions with characteristic "open window" phenomenon. Conclusion: Combining the clinical manifestations of the patient, the morphological characteristics of the cells in the smear and cell block of the ascites can provide important clues for the diagnosis of SOC, and the immunocytochemical tests can further improve the accuracy of the diagnosis.

Six month old Cinnamomum cassia seedlings were used to simulate drought stress with polyethylene glycol(PEG 6000). The physiological indicators(osmotic substances, antioxidant enzymes, etc.) and chemical components of seedlings under different drought levels and the correlation between the two were studied. The results showed that the chlorophyll content and relative water content decreased gradually with the increase of PGE 6000(0, 5%, 10%, 15%) concentration and time(3, 5, 7 d), while the soluble protein content, soluble sugar content and catalase(CAT) activity increased, but the rising rate slowed down with the time. The activities of peroxidase(POD), superoxide dismutase(SOD), malondialdehyde(MDA) and proline content increased at first and then decreased. The content of coumarin, cinnamaldehyde, cinnamic acid and dimethoxycinnamaldehyde decreased, while the content of cinnamyl alcohol continued to increase.Under drought stress, the fluorescence signals of reactive oxygen species and no contents in roots of C. cassia seedlings were significantly stronger than those of the control.Further correlation analysis showed that coumarin content, di-methoxycinnamaldehyde content and osmoregulation substance content were significantly negatively correlated(P<0.05), cinnamic acid content was significantly negatively correlated with POD and SOD activities(P<0.01).It was found that C. cassia seedlings showed a certain degree of drought tolerance under short-term or mild drought stress, but if the drought exceeded a certain degree, the physiological metabolism of the seedlings would be unbalanced.

Objective: To know the pre-treatment drug resistance ( PDR ) status of newly reported human immunodeficiency virus type 1 ( HIV-1 ) infected individuals in Wenzhou, so as to provide guidance for antiretroviral therapy ( ART ). Methods: Totally 232 plasma samples of newly reported HIV-1 infected individuals who had not received ART were collected in Wenzhou in 2019. Virus ( HIV-1 ) RNA was extracted, followed by reverse transcription PCR and nested PCR to amplify the pol region and sequence. Resistance mutations and resistance to non-nucleoside reverse transcriptase inhibitors ( NNRTIs ), nucleoside reverse transcriptase inhibitors ( NRTIs ) and protease inhibitors ( PIs ) was analyzed. Results: The pol region sequences from 199 infected patients were obtained and the incidence of PDR was 8.04% ( 16/199 ). Eight genotypes were detected, including circulating recombinant forms ( CRFs ) CRF07_BC ( 47.24%, 94/199 ) and CRF01_AE ( 29.15%, 58/199 ) which were the dominant types. Two unique recombinant forms ( URFs ) were detected, namely URF( CRF01_AE/BC ) and URF( B/C ) . Thirty-one cases ( 15.58% 31/199 ) had drug-resistant mutations. For NNRTIs, NRTIs and PIs, 20 cases ( 64.52% ) , 2 cases ( 6.45% ) and 9 cases ( 29.03% ) with drug resistance mutations were detected, respectively. The resistance mutations to NNRTIs included K101E, K103N/R, V106I, E138K, V179D/E/T, Y181C, G190A and H221Y. Four cases each had two resistance mutations to NNRTIs. The resistance mutations to NRTIs were V75M and M184V. The resistance mutations to PIs were M46I, L33F and Q58E. For the newly released NNRTI drug Doravirine ( DOR ), two cases were found to have mutations of resistance. Conclusions The incidence of PDR among newly reported HIV-1 patients in Wenzhou is 8.04%, mainly caused by NNRTIs drug-resistant mutation. Resistance to the new drug DOR has emerged. The surveillance of drug resistance should continue to be strengthened.

Related records about discipline of diagnosis and treatment of exogenous febrile diseases by traditional Chinese medicine (TCM) were reviewed to summarize TCM knowledge about etiology, pathogenesis, progress and treatment of infectious epidemic diseases among exogenous febrile diseases. In consideration of onset time and major clinical manifestations of novel coronavirus pneumonia (NCP), this disease is considered as within the scope of pestilence in TCM, it is located in the lung, with etiology being poison of winter-warm syndrome, the viruses enter body via mouth and nose, and invade pulmonary collaterals. Based on the syndrome characteristics proposed in diagnosis and treatment schemes of various regions as well as the researches on medication rules, the present study points out the core pathogenesis of NCP is epidemic toxin invading the lung, pathogenic heat obstructing the lung and toxic heat blocking the lung. It also analyzes theoretical formula features of TCM Lianhua Qingwen and related clinical and experimental research results, in order to prove the clinical value of this drug in the outbreak of NCP.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.
