With retrieval of articles on extraordinary acupoint that were published in domesticin recent five years, one hundred and eight articles of clinical application are screened out and one hundred and twenty-three extraordinary acupoints that are extensively recognized are collected. Of those acupoints, 23 acupoints are included in the latest national standard. Of the rest 100 extraordinary acupoints, 48 acupoints are located on the running courses of fourteen meridians, 4 acupoints are shared with the meridian points and the other 52 acupoints have not been clarified to be located on the running courses of meridians based on the literature data. It is found in the collection of these acupoints that there are many extraordinary acupoints that are extensively used in clinical practice. But the nomenclatures and locations of acupoints have not been unified. Hence, a further standardization on these aspects is anticipated.

ObjectiveTo investigate the molecular mechanism of cordycepin inhibiting proliferation and promoting apoptosis of human hepatoma cells (HCCs). MethodGlioma-associated oncogene homolog 1 (Gli1) gene was silenced by small interfering RNA (siRNA) and transfected into SMMC-7721 cells, and then cell proliferation was detected by cell counting kit-8 (CCK-8) assay and cell cloning assay. SMMC-7721 cells were treated with different concentration of cordycepin, and the cell proliferation and apoptosis were examined. The expression of Gli1 and the downstream related genes was determined by Real-time polymerase chain reaction(PCR) and Western blot. ResultThe mRNA and protein expression of Gli1 in SMMC-7721 cells was higher than that in normal liver cells (P<0.01). The proliferation rate of SMMC-7721 with silenced Gli1 decreased at 72 and 96 h (P<0.05, P<0.01), and the colony-forming capacity lowered (P<0.01) compared with those in the blank group. Compared with the control, 80 μmol·L-1 and 120 μmol·L-1 cordycepin significantly inhibited the proliferation of SMMC-7721 cells at 72 and 96 h (P<0.05, P<0.01), and promoted the apoptosis of them (P<0.01). Moreover, 80 and 120 μmol·L-1 cordycepin restrained the mRNA and protein expression of Gli1 in SMMC7721 cells (P<0.05, P<0.01). At 120 μmol·L-1, cordycepin led to the decrease in the mRNA and protein levels of B-cell lymphoma-2 (Bcl-2) and c-Myc (P<0.05, P<0.01), and the increase in the mRNA and protein expression of cysteine-aspartic acid protease-3 (Caspase-3) (P<0.05). ConclusionGli1 is highly expressed in HCCs, and cordycepin can suppress the proliferation and enhance the apoptosis of HCCs by regulating Gli1 and the downstream apoptosis-related factors.

COVID-19 has swept globally and Pakistan is no exception.To investigate the initial introductions and transmissions of the SARS-CoV-2 in Pakistan,we performed the largest genomic epidemiology study of COVID-19 in Pakistan and generated 150 complete SARS-CoV-2 genome sequences from samples collected from March 16 to June 1,2020.We identified a total of 347 mutated positions,31 of which were over-represented in Pakistan.Meanwhile,we found over 1000 intra-host single-nucleotide variants(iSNVs).Several of them occurred concurrently,indicating possible interactions among them or coevolution.Some of the high-frequency iSNVs in Pakistan were not observed in the global population,suggesting strong purifying selections.The genomic epidemiology revealed five distinctive spreading clusters.The largest cluster consisted of 74 viruses which were derived from different geographic locations of Pakistan and formed a deep hierarchical structure,indicating an extensive and persistent nation-wide transmission of the virus that was probably attributed to a signature mutation(G8371T in ORF 1ab)of this cluster.Further-more,28 putative international introductions were identified,several of which are consistent with the epidemiological investigations.In all,this study has inferred the possible pathways of introduc-tions and transmissions of SARS-CoV-2 in Pakistan,which could aid ongoing and future viral surveillance and COVID-19 control.

OBJECTIVE:
To evaluate the protective function of Babao Dan (BBD) on 5-flurouracil (5-FU)-induced intestinal mucositis (IM) and uncover the underlying mechanism.
METHODS:
A total of 18 male mice were randomly divided into 3 groups by a random number table, including control, 5-FU and 5-FU combined BBD groups, 6 mice in each group. A single intraperitoneal injection of 5-FU (150 mg/kg) was performed in 5-FU and 5-FU combined BBD groups on day 0. Mice in 5-FU combined BBD group were gavaged with BBD (250 mg/kg) daily from day 1 to 6. Mice in the control group were gavaged with saline solution for 6 days. The body weight and diarrhea index of mice were recorded daily. On the 7th day, the blood from the heart of mice was collected to analyze the proportional changes of immunological cells, and the mice were subsequently euthanized by mild anesthesia with 2% pentobarbital sodium. Colorectal lengths and villus heights were measured. Intestinal-cellular apoptosis and proliferation were evaluated by Tunel assay and immunohistochemical staining of proliferating cell nuclear antigen, respectively. Immunohistochemistry and Western blot were performed to investigate the expressions of components in Wnt/β-catenin pathway (Wnt3, LRP5, β-catenin, c-Myc, LRG5 and CD44).
RESULTS:
BBD obviously alleviated 5-FU-induced body weight loss and diarrhea, and reversed the decrease in the number of white blood cells, including monocyte, granulocyte and lymphocyte, and platelet (P<0.01). The shortening of colon caused by 5-FU was also reversed by BBD (P<0.01). Moreover, BBD inhibited apoptosis and promoted proliferation in jejunum tissues so as to reduce the intestinal mucosal damage and improve the integrity of villus and crypts. Mechanically, the expression levels of Wnt/β -catenin mediators such as Wnt3, LRP5, β-catenin were upregulated by BBD, activating the transcription of c-Myc, LRG5 and CD44 (P<0.01).
CONCLUSIONS
BBD attenuates the adverse effects induced by 5-FU via Wnt/β-catenin pathway, suggesting it may act as a potential agent against chemotherapy-induced intestinal mucositis.

OBJECTIVE:
A strain of Aspergillus niger (A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain (FA-WB) were evaluated.
METHODS:
Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity (ORAC), cellular antioxidant activity (CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity.
RESULTS:
The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species (ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-a, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide (LPS).
CONCLUSION
Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid.

OBJECTIVE:
Traditional Chinese medicine plays a significant role in the treatment of the pandemic of coronavirus disease 2019 (COVID-19). Tanreqing Capsule (TRQC) was used in the treatment of COVID-19 patients in the Shanghai Public Health Clinical Center. This study aimed to investigate the clinical efficacy of TRQC in the treatment of COVID-19.
METHODS:
A retrospective cohort study was conducted on 82 patients who had laboratory-confirmed mild and moderate COVID-19; patients were treated with TRQC in one designated hospital. The treatment and control groups consisted of 25 and 57 cases, respectively. The treatment group was given TRQC orally three times a day, three pills each time, in addition to conventional Western medicine treatments which were also administered to the control group. The clinical efficacy indicators, such as the negative conversion time of pharyngeal swab nucleic acid, the negative conversion time of fecal nucleic acid, the duration of negative conversion of pharyngeal-fecal nucleic acid, and the improvement in the level of immune indicators such as T-cell subsets (CD3, CD4 and CD45) were monitored.
RESULTS:
COVID-19 patients in the treatment group, compared to the control group, had a shorter negative conversion time of fecal nucleic acid (4 vs. 9 days, P = 0.047) and a shorter interval of negative conversion of pharyngeal-fecal nucleic acid (0 vs. 2 days, P = 0.042). The level of CD3
CONCLUSION
Significant reductions in the negative conversion time of fecal nucleic acid and the duration of negative conversion of pharyngeal-fecal nucleic acid were identified in the treatment group as compared to the control group, illustrating the potential therapeutic benefits of using TRQC as a complement to conventional medicine in patients with mild and moderate COVID-19. The underlying mechanism may be related to the improved levels of the immune indicator CD3
