Abstract: Objective To summarize the clinical characteristics of 35 patients with human monkeypox in Chengdu City, in order to provide theoretical basis for prevention and control of monkeypox epidemic in China. Methods A total of 35 patients diagnosed with monkeypox infection by Chengdu CDC from July 1 to July 23, 2023 were included in our study. The results of general clinical data, blood laboratory tests, lymph node ultrasound and chest CT results were collected in order to analyze the clinical features of human monkeypox patients in Chengdu City. Results All 35 monkeypox patients were young adult males, and there were no serious or fatal cases. Among them, 32 cases (91.4%) were men who have sex with men (MSM), and 30 cases had engaged in male-to-male sexual behavior within 21 days prior to the onset of the disease, of which 13 cases had taken protective measures. Fever symptoms were observed in 26 cases (74.3%) of the patients, with 19 cases experiencing fever within 1-6 days after the appearance of rash. The initial rash commonly occurred in the male external genitalia. Color ultrasound examinations indicated that all patients had swollen inguinal lymph nodes. C-reactive protein was elevated in 26 cases (74.3%) of patients, and 19 cases showed CD3+CD4+T/CD3+CD8+T< 1.0. 15 cases (42.8%) of the patients were infected with both monkeypox virus and HIV, 28.5% (10/35) of patients had concomitant skin infections and anorectal proctitis,respectively. The mean time from rash onset to the shedding of rash scabs was 14.8 days. Conclusions The MSM population in sexually active age group is the main infection object of human monkeypox virus. In monkeypox patients in Chengdu City, the rash starting at genital areas and rash occurring before systemic symptoms were common. Swollen inguinal lymph nodes are especially common in monkeypox patients. Skin infection and anorectal proctitis are the most common complications in monkeypox patients in Chengdu City. The abnormal cellular immune function in monkeypox patients is mainly reflected in the inverted ratio of CD3+CD4+T/CD3+CD8+T. Currently, there is no evidence to suggest that protective measures during male-to-male sexual behavior can reduce the risk of human monkeypox infection.
3.Bowel preparation before colorectal surgery: from intestinal mucosal barrier.
Acta Academiae Medicinae Sinicae 2004;26(5):591-594
The routine bowel preparation before colorectal surgery usually includes mechanical and medicine preparations, with the original purpose of reducing complications such as anastomosis leakage, wound, and abdominal infections. Many domestic hospitals are still employing the methods of three-day bowel preparation, while in the West, the way of this preparation has dramatically changed. In last decade, one-day preparation has been widely accepted internationally, with two major medications of sodium phosphate and polyethylene glycol frequently used in the clinic. It has also been indicated that excessive mechanical and medicinal bowel preparations exert harmful effects on the combined intestinal barrier, and may result in various complications. A few reports have suggested to omit the mechanical bowel preparation before surgery, which is still under controversy, however, well-designed clinical trials are needed to readjust and regulate the duration and intensity of bowel preparation before colorectal surgery in China.

OBJECTIVETo evaluate clinical efficacy of suture anchors in treating acute injuries of medial collateral ligament (MCL) of knee at degree III.
METHODSTwenty-seven patients with degree III acute MCL injuries of knee were treated with suture anchors from January 2007 to June 2011. There were 15 males and 12 females, aged from 19 to 56 (averaged 32.6) years old. The time from injury to operation was 3 to 10 days, averaged 6 days. Symptoms and physical signs before and after treatment were observed, Lysholm scoring were used to evluated clinical efficacy.
RESULTSAll patients were followed up from 16 to 30 months with an average of 21.6 months. The stability of knee joints was good in all patients. Abduction stress test was negative when the knee joint was straightened at 0 degrees and flexed at 30 degrees. The average degree of flexed knee (67.00 +/- 5.80) degrees preoperatively was lower than that of postoperatively (136.50 +/- 6.30) degrees at 1 year. According to Lysholm scoring, preoperative scores ranged from 30 to 43 points, averaged 36.46 +/- 1.48; 1 year after operation ranged from 87 to 100 with an average of 91.50 +/- 3.80 and higher than postoperative. Twenty patients got an excellent results, 5 good and 2 fair.
CONCLUSIONSuture anchors in treating acute injuries of medial collateral ligament of knee at degree III has following advantages: small range of tissue dissection, easy to operate, reliable fixation and less complications.

5.Approaches of preoperative assessment of liver function in cirrhotic patient: current status and future prospects.
Acta Academiae Medicinae Sinicae 2006;28(6):849-852
Risks persists during liver resection in the patients with cirrhosis. Routine examinations usually are unable to predict the morbidity and mortality following surgery. Evaluation approaches of liver function, including aminotransferase, bilirubin, albumin, prothrombin time, Child-Pugh classification, and indocyanine green (ICG) test, currently remain the most important method to determine the prognosis of liver resection, especially in cirrhotic patients. However, all these approaches have their weakness. Some new methods, including non-invasive ICG test, liver function evaluation by hepatic imaging, and remnant hepatic function test, are awaiting further investigation. This article reviews the current status and future prospect in the assessment of liver functions.

Objective To explore the expression of hypoxia-inducible factor-1?(HIF-1?) protein and its mRNA in cultured cortical neurons after hypoxia,ischemia or hypoxia-ischemia(HI) and explore the possibilities of HIF-1? gene therapy in HI neurons.Methods The in vitro models of HI,pure hypoxia and pure ischemia were established using embryonic day 16-18 rats cortical neurons.Immunohistochemical and in-situ hybridization were performed to examine the expression of HIF-1? protein and its mRNA at different reperfusion time points in neurons.Results The expression of HIF-1? protein was very week in normoxic cultured neurons,but was up-regulated while treated with hypoxia and(or) ischemia.HIF-1? expression reached peak at 4 to 8 h after reperfusion with HI,which were statistically significant higher than that at other time points(Pa=0),and decreased gradually at 12 h.Furthermore,HIF-1? protein expression was significantly higher in HI group compared with that in the pure hypoxia or ischemia group(Pa=0).HIF-1? mRNA reached peak immediately after HI,decreased gradually at 2 h,and returned to the baseline at 8 h after reperfusion.Conclusions HIF-1? expression on cortical neurons is regulated differently with hypoxia,ischemia or HI treatment,HIF-1? gene therapy for HI neurons maybe a useful method in the future studies.
7.Regulatory Effects of Long Non-coding RNA on Tumorigenesis.
Acta Academiae Medicinae Sinicae 2015;37(3):358-363
Long non-coding RNAs(LncRNA)may play a key role in tumorigenesis by regulating gene expression and intervening transcription. Recent studies have demonstrated that a series of patterns including protein modification,chromosomal reconstruction,regulation of target gene expression,transcription intervention,epigenetic modification,and natural antisense transcript are involved in this process. This article reviews recent research advances in this aspect with an attempt to better understand the role of LncRNA in tumorigenesis.

This study was aimed to investigate the effect of RPMI 1640 and IMDM on the development of human peripheral blood monocyte-derived dendritic cells. Under the same cytokines and culture conditions, the different medium types were tested, and the morphology of mature and immature dendritic cells was observed by microscopy, the cell phenotype and endocytosis ability were detected by flow cytometry. Furthermore, the immunoregulatory function of various DC was analyzed by mixed lymphocyte reaction (MLR), the expression of cytokine in culture supernatant of MLR system was also analyzed by Bio-plex technology. The results showed that there were no difference in morphology, CD14, CD83 expression and endocytosis ability between IMDM-cultured DC and RPMI-1640 medium-cultured DC, but there was a lower expression of CD1a in IMDM-cultured DC. Moreover, DC cultured with IMDM displayed a significant reduction in stimulating T cell proliferation, and highly expressed IL-6, IL-8 and IL-10, but low expressed IL-12. It is concluded that the different cultural mediums can induce DC with different functions and DC cultured with IMDM may correlated with induction of immune tolerance. The results of this study will provide a new idea for DC clinical application.

OBJECTIVESTo study the correlation and effect of smoking on the semen quality of men.
METHODS61 men, non-smoker, who had one or more children as normal fertility control group and adult males attending the infertility clinic, including 110 non-smokers and 191 smokers, were recruited for the study. The smokers were divided into subgroups according to the amount and duration of smoking. Semen parameters(volume, sperm density, viability, motility and morphology) were examined and seminal plasma contents of Zn, Cu and superoxide dismutase (SOD) were determined.
RESULTSThe semen volume, pH, sperm density, viability and forward progression, as well as the seminal plasma contents of Zn, Cu and SOD were much lower in the medium, heavy and long-term smokers than in the non-smokers(P < 0.01). The sperm density, viability and forward progression, and the seminal plasma Zn, Cu and SOD levels were negatively correlation with the amount and duration of cigarette smoking(P < 0.001).
CONCLUSIONSThe effect of smoking on semen parameters of infertile men were dose-effect and time-effect relationship. Medium, heavy and long-term smoking adversely affected the semen quality in a population of men visiting the infertility clinic.

OBJECTIVETo evaluate the application, indications and outcomes of free flaps for ora-maxillofacial traumatic defects reconstruction.
METHODSTwenty consecutive cases of ora-maxillofacial the traumatic defects reconstruction with free flaps were reviewed. All clinical data including causes of injuries, the type of defects, selection of free flaps, perioperative complications and the follow-up were analyzed.
RESULTSAll the cases underwent free flap reconstruction for ora-maxillofacial traumatic defects: 8 cases with soft tissue defects, 12 cases with soft and hard tissue defects. Fifteen patients received two-stage operation and 5 patients underwent primary reconstruction at the time of debridement or fracture reduction. Twenty free flaps were applied for the reconstruction, 11 cases with fibula flap, 1 case with iliac crest free flap, 7 cases with radial forearm flap and 1 case with scapula flap. No flap failure occurred. The successful rate of free flaps transfer was 100%.
CONCLUSIONSThe free flaps transfer is reliable and can reconstruct the ora-maxillofacial traumatic soft and hard tissue defects. Fibula and radial forearm free flap are the most common used flaps. Early aggressive surgery with free flaps transfer for traumatic defects can prevent the scar contracture and tissue displace, which can shorten the treatment period and improve the final outcome.
