Abstract: Due to the continued emergence of multiple variants of SARS-CoV-2, the ongoing pandemic has resulted in severe mortality over the past two years. After the Alpha, Beta, Gamma and Delta variants, the most recent new variant of concern (VOC) strain to emerge is Omicron (B.1.1.529), which evolved as a result of the accumulation of a large number of mutations. The Omicron variant, which has a much higher transmission rate than the Delta variant, soon replaced the Delta variant and others, is now the dominant variant worldwide. The emergence of Omicron poses new challenges for the prevention and control of COVID-19 and has raised a number of concerns worldwide. Recently, cases of Omicron infection have been reported in several parts of China, and therefore this paper provides a comprehensive analysis and summary of the epidemiology and immune escape mechanisms of the Omicron variant. We also suggest some therapeutic strategies against the Omicron variant, including rapid diagnosis, genome analysis of emerging variants, ramping up of vaccination drives and receiving booster doses, updating the available vaccines, designing of multivalent vaccines able to generate hybrid immunity, up-gradation of medical facilities and strict implementation of adequate prevention and control measures need to be given high priority to handle the on-going COVID-19 pandemic successfully.
6.Body Position Adjustment May Facilitate Capsule Endoscopic Real-Time Examination in Patients with a Large Amount of Food Retention in the Stomach.
Clinical Endoscopy 2014;47(3):266-269
A patient with acute obscure gastrointestinal bleeding was found to have a large amount of food retention in the stomach after fasting for >12 hours. We tried to adjust the patient's body position to facilitate capsule endoscopic examination. The patient laid on the bed on his right side, which is the position required for a normal procedure, and then his hip was raised while his upper body was lowered gradually until the pylorus appeared at the center of the screen of the real-time monitor. It took 15 minutes of body position adjustment to make the pylorus appear at the center of the monitor and another 5 minutes for the capsule endoscope to enter the duodenum. The lesion was ultimately found at the terminal small intestine.

OBJECTIVETo observe the therapeutic effect of Qilin Pills combined with clomiphene on idiopathic oligoasthenospermia.
METHODSWe randomly assigned 300 patients with idiopathic oligoasthenospermia to a trial (n = 156) and a control group (n = 144) to be treated with Qilin Pills (6 g, tid) combined with clomiphene (50 mg, qd) and clomiphene alone (50 mg, qd), respectively, both for a course of 12 weeks. Before and after 4, 8, and 12 weeks of medication, we determined sperm concentration, the percentages of grade a and grade a + b sperm, sperm motility, and the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T), followed by evaluation of the clinical efficacy of Qilin Pills with the pregnancy rate in the patients' spouses as the secondaty therapeutic indexes.
RESULTSCompared with the baseline, both groups of patients showed remarkably improved semen parameters and hormone levels after treatment (all P < 0.01). After 4, 8, and 12 weeks of medication, statistically significant differences were observed between the trial and control groups in sperm concentration ([17.06 ± 2.24] vs [15.07 ± 2.48], [22.10 ± 2.65] vs [18.11 ± 2.97], and [28.13 ± 3.59] vs [21.21 ± 3.60] x 10(6)/mL, P < 0.01), the percentage of grade a sperm ([15.03 ± 2.39] vs [13.08 ± 2.51], [21.08 ± 3.16] vs [16.04 ± 3.05], and [28.08 ± 4.70] vs [20.14 ± 4.74]%, P < 0.01), the percentage of grade a + b sperm ([30.10 ± 5.07] vs [26.21 ± 3.96], [38.08 ± 5.64] vs [30.07 ± 4.80], and [48.04 ± 6.49] vs [35.28 ± 4.77]%, P < 0.01), sperm motility ([42.04 ± 4.86] vs [40.29 ± 4.19], [52.05 ± 5.58] vs [48.03 ± 4.40], and [65.03 ± 5.13] vs [56.67 ± 4.99]%), the FSH level ([7.75 ± 1.38] vs [7.20 ± 1.17], [10.83 ± 1.23] vs [9.10 ± 1.32], and [14.22 ± 0.84] vs [12.06 ± 1.45] IU/L, P < 0.01), the LH level ([10.05 ± 1.68] vs [9.18 ± 1.54], [13.96 ± 1.68] vs [11.99 ± 1.71], and [19.01 ± 2.42] vs [15.86 ± 2.08] IU/L, P < 0.01) and the T level ([19.19 ± 192] vs [18.34 ± 1.79] [21.06 ± 1.63] vs [20.06 ± 1.56], and [24.63 ± 1.06] vs [22.03 ± 1.49] nmol/L, P < 0.01). The pregnancy rate in the patients' spouses was significantly higher in the trial than in the control group at 4, 8, and 12 weeks (1.92 vs 0.69, 4.81 vs 3.47, and 11.54 vs 8.33%, P < 0.01). There were no statistically significant differences in drug tolerance between the two groups (P > 0.05). No obvious adverse reactions were observed.
CONCLUSIONQilin Pills combined with clomiphene can evidently improve the seminal quality and hormone level of oligoasthenospermia patients with no obvious adverse events. However, its long-term efficacy and tolerance deserve further clinical investigation.

The traditional Chinese medicine of Radix Hedysari plays an important role in invigorating gas for as-cending, benefiting blood for promoting production of fluid, and promoting circulation for removing obstruction in collaterals, which is consistent with the principle of treatment for osteoporosis. This study is designed to investigate the bioactive components on increasing peak bone mass (PBM) by exploring the spectrum-effect relationship between chromatography fingerprints and effect. Multiple indicators are selected to evaluate the pharmacological activity. In fingerprints, 21 common peaks are obtained, five of which are identified. Furthermore, gray relational analysis (GRA) is a quantitative method of gray system theory and is used to describe the correlation degree of common peaks and pharmacological activities with relational value. 21 components are then divided into three different regions, of which ononin and calycosin play an extremely significant role in increasing PBM. In addition, factor analysis and hierarchical cluster analysis (HCA) are used to screen the optimal producing area for Radix Hedysari. This provides a comprehensive and efficient method to improve the quality evaluation of Radix Hedysari, confirming the bioactive components for PBM-enhancement and further develop its medicinal value.

OBJECTIVETo evaluate the causes of alanine aminotransferase (ALT) level elevation in HBsAg-positive chronic hepatitis B (CHB) patients with low HBV DNA loads.
METHODSOne hundred nineteen HBsAg positive CHB patients with both serum HBV DNA loads less than 1000 copies/ml and ALT more than 1.25 upper limits of normal (ULN) lasting for at least 6 months were enrolled in this study. Patients co-infected with hepatitis C virus or HIV or suffering from other liver diseases were not included. HBV DNA loads were assayed by PCR. Serological biochemistry and liver biopsy histopathological changes and clinical characteristics of the patients were analyzed.
RESULTSOf the 119 patients 102 were males and 17 were females. The mean age of the patients was (33.9+/-9.7) years and their body mass index (BMI) was (23.4+/-3.7) kg/m2. Mean ALT levels were (150.0+/-166.6) U/L and AST levels were (102.4+/-193.2) U/L. Liver biopsies showed hepatic steatosis in 26.9 % (32/119) of the cases, chronic hepatitis in 53.8% (64/119), non-specific changes in 12.6% (15/119), and 1 without any change. However, hepatic steatosis was more frequently seen in patients taking nucleoside analogs (56.7%), x2=10.394, Probability value less than 0.01. BMI, apolipoprotein B (APO-B), triglyceride, cholesterol and uric acid were all significantly higher in patients with hepatic steatosis than those without (t values were 5.369, 4.276, 3.216, 4.223 and 2.438 respectively, all P less than 0.05) while ALT, AST and apolipoprotein A were much lower in those with steatosis than those without (t values were -2.234, -3.877 and -2.956 respectively, all P less than 0.05). Obesity, dyslipidemia and hyperuricemia were more frequently seen in patients with steatosis than in patients without it (x2 value 3.829, 7.659, 13.389, 0.549, all P less than 0.05). The severity of inflammation and fibrosis were also more significant in patients with steatosis (x2 value 20.978, 17.550, all P less than 0.05). As compared to those patients without specific changes, serum levels of ALT, AST, GGT in patients with chronic hepatitis were obviously higher, all P less than 0.05. In contrast, there were no significant differences in mean age, BMI, male preference, obesity, diabetes, dyslipidemia or hyperuricemia, and the levels of triglyceride, cholesterol, and fasting plasma glucose between the two groups.
CONCLUSIONOur data indicate that hepatic steatosis might be a factor associated with elevated ALT levels in HBsAg-positive CHB patients with low HBV DNA loads, especially in patients treated with nucleoside analogs.
