The novel coronavirus disease (COVID-19) pandemic is emerging as a global health threat and shows a higher risk for men than women. Thus far, the studies on andrological consequences of COVID-19 are limited. To ascertain the consequences of COVID-19 on sperm parameters after recovery, we recruited 41 reproductive-aged male patients who had recovered from COVID-19, and analyzed their semen parameters and serum sex hormones at a median time of 56 days after hospital discharge. For longitudinal analysis, a second sampling was obtained from 22 of the 41 patients after a median time interval of 29 days from first sampling. Compared with controls who had not suffered from COVID-19, the total sperm count, sperm concentration, and percentages of motile and progressively motile spermatozoa in the patients were significantly lower at first sampling, while sperm vitality and morphology were not affected. The total sperm count, sperm concentration, and number of motile spermatozoa per ejaculate were significantly increased and the percentage of morphologically abnormal sperm was reduced at the second sampling compared with those at first in the 22 patients examined. Though there were higher prolactin and lower progesterone levels in patients at first sampling than those in controls, no significant alterations were detected for any sex hormones examined over time following COVID-19 recovery in the 22 patients. Although it should be interpreted carefully, these findings indicate an adverse but potentially reversible consequence of COVID-19 on sperm quality.

ORF3 protein, the single accessory protein encoded by porcine epidemic diarrhea virus (PEDV), is related to viral pathogenicity. In order to determine the cytoplasmic location signal of PEDV ORF3, we constructed a series of recombinant plasmids carrying full-length or truncated segments of PEDV DR13 ORF3 protein. When the acquired plasmids were transfected into Vero cells, expression and distribution of the EGFP-fused full-length ORF3 protein and its truncated forms in the cells were observed by laser confocal microscopy. The results showed that ORF3 protein or their truncated forms containing 40-91 aa segment including two transmembrane domains were localized in the cytoplasm, whereas ORF3 truncated peptides without the 40-91 aa segment were distributed in the whole cell (in both cytoplasm and nucleus). This suggests that the 40-91 aa is the key structural domain determining cytoplasmic location of PEDV ORF3 protein. The discovery provides reference for further clarifying intracellular transport and biological function of PEDV ORF3 protein.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

OBJECTIVE: To evaluate the efficacy of electro-acupuncture (EA) or transcutaneous electrical acupoint stimulation (TEAS) on perioperative cerebral blood flow (CBF) and neurological function in ischemic stroke (IS) patients undergoing carotid artery stenting (CAS). METHODS: In total, 124 consecutive IS patients were randomly allocated to the EA, TEAS, and sham groups (groups A, T, and S; 41, 42, and 41 cases, respectively) by software-derived random-number sequence. Groups A and T received EA and TEAS, respectively, at the Shuigou (GV 26) and Baihui (GV 20), Hegu (LI4) and Waiguan (TE 5) acupoints. Group S received sham EA. The stimulation was started from 30 min before surgery until the end of the operation. The primary outcome was the CBF at 30 min after surgery, which was measured by transcranial Doppler sonography. The secondary outcomes included hyperperfusion incidence and neurological function. National Institutes of Health Stroke Scale (NIHSS) and General Evaluation Scale (GES) scores were recorded at 1 week, 1 month, and 3 months postoperatively. RESULTS: Mean CBF velocity at 30 min after surgery in groups A and T was much lower than that in Group S (P < 0.05); the incidence of hyperperfusion in Groups A and T was also lower than that in group S (P <0.05). Acupuncture was an independent factor associated with reduced incidence of hyperperfusion (OR=0.042; 95% CI: 0.002-0.785; =0.034). NIHSS and GES scores improved significantly at 1 week postoperatively in Groups A and T than in Group S (P < 0.05). Relative to Group S, groups A and T exhibited significantly lower incidences of moderate pain, as well as higher incidences of satisfaction with anesthesia, at 1 day postoperatively (P < 0.05). CONCLUSIONS EA or TEAS administered in combination with local anesthesia during CAS can inhibit transient increases in CBF, reduce the incidence of postoperative hyperperfusion, and improve neurological function.

Diemailing~® Kudiezi Injection( DKI) is widely used in the treatment of cerebral infarction,coronary heart disease and angina pectoris. Long-term clinical application and related research evidence showed that DKI has a good effect in improving the clinical symptoms of cardiovascular and cerebrovascular diseases. However,this injection has not been included in any clinical practice guideline. It has been found that the use of DKI is in wrong way in clinical practice in recent years. Therefore,clinical experts from the field of cardiovascular and cerebrovascular diseases nationwide are invited to compile this expert consensus in order to guide clinicians.GRADE system is used to grade the quality of evidence according to different outcomes according to degrading factors. Then it forms the recommendation or consensus suggestion through the nominal group method. The formation of expert consensus mainly considers six factors: quality of evidence,economy,efficacy,adverse reactions,patient acceptability and others. Based on these six aspects,if the evidence is sufficient,a " recommendation" supported by evidence is formed,and GRADE grid voting rule is adopted. If the evidence is insufficient,a " consensus suggestions" will be formed,using the majority voting rule. In this consensus,the clinical indications,efficacy,safety evidences and related preliminary data of DKI were systematically and comprehensively summarized in a concise and clear format,which could provide valuable reference for the clinical use of DKI. This consensus has been approved by China association of Chinese medicine which is numbered GS/CACM 202-2019.

OBJECTIVE: Several clinical studies were performed on multi-segment intramedullary primary spinal cord tumors. However, no clinical study focused on the relationship between different vertebral segments intramedullary tumors involvement and neurological functions, as well as prognosis of the patients. This prospective study was performed to compare clinical analysis on neurological functions and prognosis of the patients with intramedullary spinal cord primary tumors. METHODS: A prospective cohort study was performed in a single medical center, Neurosurgical Department, Peking University Third Hospital. Between Jan. 1, 2010 and Dec. 30, 2015, 135 patients underwent microsurgery for intramedullary primary spinal cord tumors. The intramedullary tumor length occupying 3 or more vertebral body levels was considered as multiple segments intramedullary primary spinal cord tumor, and occupying one or two vertebral body levels considered as seldom segments. Preoperative and postoperative functions were assessed using IJOA (improved Japanese orthopaedic association) scoring system, and analyzed using the appropriate statistical tests. RESULTS: Among the 135 patients, 52 cases had seldom segments intramedullary primary spinal cord tumors, and 83 cases had multiple segments. In the seldom group, 32 (62%) patients presented with normal urine and stool function, 8 (15%) patients with severe dysfunction, 7 (14%) with slight dysfunction, and 5 (9%) with incontinence, and 30 (58%) patients demonstrated various degrees of limbs weakness. The preoperative IJOA scores of the patients were 16.9±2.4. The postoperative IJOA scores at the end of 3 months were 16.6±2.3. The current IJOA scores until the end of the follow-up were 17.5±4.4. In the multiple group, 37 (45%) patients presented with normal urine and stool functions, 26 (31%) patients with slight dysfunction, 11 (13%) with severe dysfunction, and 9 (11%) with incontinence, and 62 (75%) patients demonstrated various degrees of limbs weakness. The preoperative IJOA scores of the patients were 15.6±3.4. The postoperative IJOA scores at the end of 3 months were 15.5±3.8. The current IJOA scores until the end of the follow-up were 16.9±5.8. The difference of presenting urine and stool dysfunction (Z=-1.35, P=0.18) was not statistically significant between the different patient groups. However, the difference of presenting limbs weakness (Z=-2.06, P=0.04) was statistically significant between the two groups. Most patients with multiple segment intramedullary tumors suffered from various limbs weakness. The difference of the preoperative IJOA score (P=0.02) and the postoperative early IJOA score (P=0.004) of the patients was statistically significant between the seldom and multiple segments groups. Preoperative and early postoperative neurological function of the patients was better with seldom segments tumor than with multiple segments tumor. Most patients with multi-segment intramedullary tumors experienced various limbs weakness. However, the difference of long-term neurological function (P=0.12) between the seldom and multiple segments groups was not statistically significant. The neurological function of the patients with multiple segments intramedullary tumor was remarkably improved after physical therapy. CONCLUSION Perioperative neurological function of the patients with seldom segments primary tumor was superior to that of the patients with multiple segments primary tumor, especially for limb strength. The neurological function of the patients with multiple segments intramedullary primary tumor was remarkably improved after physical therapy during long-term follow-up.

OBJECTIVETo explore the differences of CD146 expression in adult and children's acute B cell lymphoblastic leukemia(B-ALL), and its relation with clinical features, molecular biological and cytogenctic claracteristics.

METHODSThe expression of CD146 in bone marrow samples from adult and children's B-ALL patients were detected by flow cytometry (FCM) and the relation of CD146 abnormal high expression with the patients' clinical features, molecular biological and cytogenetical characteristics, as well as other antigens were analyzed.

RESULTSThe abnormal high expression rates of CD146 in adult and children's B-ALL patients were 29.17% and 9.09% respectively, showing that the expression rate of CD146 in adult patients was higher than that in children's patients(P<0.05). In adult B-ALL, CD146 was positively related with CD64 and CD117, while in children's B-ALL CD146 was positively related with CD71 and CD58 (P<0.05). After 1 course of standardized chemotherapy, the complete remission rates in adult and children's B-ALL patients with abnormal high expression of CD146 both were low as compared with adult and children's B-ALL without abnormal high expression of CD146 (P<0.05).

CONCLUSIONThe expression rate of CD146 in adult B-ALL is higher than that in children's B-ALL. The CD146 positively relates with poor prognostic antigens, the CD146 may be one poor prognosis marker.
