Objective:To investigate the correlation of epithelial lesions among different biopsy sites in the female lower genital tract and the relationship between age and lesion distribution.Methods:A total of 406 148 patients with cervical biopsy specimens archived at the Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University from January 2010 to December 2021 were analyzed. Among them, 70 309 cases (17.31%) had concurrent vaginal biopsies, and 16 073 cases (3.96%) had concurrent vulvar biopsies. (1) Cases were divided into four 3-year intervals to compare vaginal or vulvar biopsy rates and high-grade squamous intraepithelial lesion (HSIL) or worse (HSIL +) detection rates across time periods. (2) Correlations between cervical lesions and vaginal or vulvar lesions were assessed. (3) Patients were stratified into three age groups (<30, 30-49, and ≥50 years) to compare vaginal or vulvar HSIL + detection rates. Results:Mean ages of patients with cervical, vaginal, and vulvar biopsies were (41.3±11.0), (47.4±12.5), and (41.9±13.2) years, respectively. Patients with vaginal biopsy were significantly older than cervical or vulvar groups (all P<0.001). (1) Vaginal biopsy rates increased markedly from 7.37% (2010—2012) to 22.76% (2019—2021; χ2=9 205.01, P<0.001); vulvar biopsy rates increased slightly from 2.80% to 5.69% ( χ2=1 777.25, P<0.001). Correspondingly, vaginal HSIL + detection rates rose from 0.28% to >0.5% (0.56% in 2013—2015, 0.59% in 2016—2018, 0.51% in 2019—2021; χ2=134.70, P<0.001), while vulvar HSIL + rates increased from 0.03% to 0.33% ( χ2=56.54, P<0.001). (2) Weak correlation existed between cervical and vaginal lesions ( r=0.28; P<0.001; n=70 309), while cervical-vulvar correlation was weaker ( r=0.22, P<0.001; n=16 073). (3) Vaginal HSIL + detection rates were higher in cervical HSIL + patients aged 30-49 years (26.65%) and ≥50 years (26.79%) versus <30 years (14.63%; both P<0.001). Conversely, vulvar HSIL + detection rates were higher in the <30 years group (23.08%) versus 30-49 years (13.83%) and ≥50 years (12.89%; both P<0.05). Conclusions:Vaginal or vulvar lesion detection rates increase with biopsy frequency. Vaginal lesions correlate with cervical abnormalities, whereas vulvar lesions are relatively independent. In cervical HSIL + patients, those <30 years are more prone to have vulvar HSIL +, while those ≥30 years show higher vaginal HSIL + incidence. These age-specific distribution patterns inform optimized biopsy strategies.

Wound healing is a complex and highly coordinated physiological process,involving the interaction of various cell types,growth factors,and extracellular matrix.Its goal is to repair damaged tissue and restore skin integrity and function.However,various internal and external factors can lead to delayed or abnormal wound healing,causing significant pain and economic burdens for patients.Therefore,it is of great clinical significance to develop safe and effective treatments to promote wound healing.In recent years,research on natural products in the field of wound healing has attracted widespread attention,and berberine,a biological alkaloid with multiple pharmacological activities,has garnered considerable attention for its remarkable effects in promoting wound healing.This article provides an in-depth review on the progress in the application of berberine in wound healing from multiple perspectives.

Objective To establish a rapid detection method for zika virus based on direct amplification re-al-time fluorescent quantitative reverse transcription polymerase chain reaction(RT-PCR)technique.Methods A direct amplification RT-PCR technique for the rapid detection of zika virus in 5 samples(whole blood,serum,saliva,throat swab and urine)was established by using a special function DNA polymerase and a preferred PCR enhancer.Results The detection limits of the 5 samples were 103 PFU/mL in serum,102 PFU/mL in urine,throat swab,and saliva,and 104 PFU/mL in whole blood.The coefficient of goodness-fit of stand-ard curves was above 0.98,and the amplification efficiency was 90％-110％.Zika virus nucleic acid was suc-cessfully amplified,but non-zika virus nucleic acid was not amplified.Based on the repeatable detection of sam-ples from urine,whole blood,and saliva,the variation coefficient of 6 repeated Ct values at 106 PFU/mL and 102 PFU/mL concentrations were all＜5％.The zika virus detection method established by the direct amplifi-cation RT-PCR technique was consistent with the detection results of conventional RT-PCR technique.Only two serum samples were detected in eight zika virus samples,and the remaining 62 non-zika virus samples and 12 negative samples were not amplified.Conclusion A rapid detection method for zika virus based on direct ampli-fication RT-PCR technique is successfully established.The method is simple,rapid,sensitive and specific.

Enteral nutrition (EN) is an important way in the treatment of Crohn′s disease (CD) . Although the exact pathogenesis of CD is still unknown, CD patients have some significant pathological features compared with healthy population, including intestinal flora dysbiosis, excessive intestinal mucosal inflammation, intestinal mucosal damage, mesenteric fat abnormality, etc. This review explores the mechanism of EN in the treatment of CD in order to better understand the role of EN in modifying CD disease progression and to promote the clinical management of CD.

The rapid screening of tumor markers is a challenging task for early diagnosis of cancer. This study aims to use highly sensitive chemiluminescent protein microarray technology to efficiently screen a variety of low abundance tumor related markers. A new material, termed integrated polydimethylsiloxane modified silica gel (iPDMS), was obtained by adding a surface polymerization initiator with olefin end to the conventional polydimethylsiloxane, and fixing into the three-dimensional structure of polydimethylsiloxane by thermal crosslinking through silicon hydrogen bonding. In order to make the iPDMS material resistant to non-specific protein adsorption, a poly(OEGMA) polymer brush was synthesized by surface-initiated atom transfer radical polymerization at the active initiation site. Finally, 20 tumor-related antigens were printed into the specific areas of the microarray by high-throughput spray printing technology, and assembled into 48-well detection microtiterplates of the iPDMS microarray. It was found the VEGFR and VEGF121 autoantibodies that obtained from 8 common tumors (breast cancer, lung cancer, colon cancer, gastric cancer, liver cancer, leukemia, lymphoma and ovarian cancer) can be used as potential tumor markers. The chemiluminescence labeled iPDMS protein microarray can be used for the screening of tumor autoantibodies at early stage.

OBJECTIVETo investigate the predictive value of procalcitonin(PCT) in postoperative intra-abdominal infections (IAI) after definitive operation of intestinal fistulae(IF).

METHODSWith the exclusion of emergence operation, preoperative clinical infection, preoperative renal or hepatic dysfunction, and age less than 18 years, a total of 356 consecutive patients who underwent elective digestive tract reconstruction of intestinal fistulae from February 2012 to December 2015 at Intestinal Fistula Center of Jinling Hospital were prospectively enrolled in the study. All the patients were divided into IAI group (26 cases, 21 of anastomosis leakage and 5 of peritoneal abscess) and non-IAI group (330 cases) based on the existence of postoperative IAI. The non-IAI group was then divided into two subgroups of other infection (93 cases) and non-infection(237 cases) according to the presence of other infections. Plasma PCT level, serum CRP concentration and WBC count were assessed preoperatively and on postoperative days (PODs) 1, 3, 5, 7 by immunofluorescence, turbidimetry and automatic blood analyzer, respectively. The predictive value of each marker for IAI was calculated by receiver operating characteristic (ROC) curve.

RESULTSThere was no significant difference in general clinical data between IAI and non-IAI group (all P>0.05). The proportions of multi-IF (53.8%, 14/26) and colectomy (61.5%, 16/26) in IAI group were higher than those of non-IAI group [20.0% (66/330), χ=15.847, P=0.000 and 31.2%(103/330), χ=9.961, P=0.002]. Differences of preoperative PCT, CRP and WBC levels among IAI, other infection and non-infection groups were not significant. These three markers all increased obviously and immediately after surgery. PCT and WBC values reached the peak point on POD 1, whereas CRP on POD 3. In IAI group, mean PCT values were (5.4±4.2) μg/L, (2.9±1.9) μg/L and (1.6±1.8) μg/L on POD 1, POD 3 and POD 5, respectively, which were higher than those of other infection group [(4.2±8.7) μg/L, (1.9±3.8) μg/L and (0.6±0.8) μg/L] and non-infection group [(2.7±5.8) μg/L, (1.1±1.7) μg/L and (0.5±0.7) μg/L, all P<0.05]. Mean CRP values in IAI group were 99.4 mg/L and 183.9 mg/L respectively on POD 1 and POD 3,and mean WBC values of IAI group on POD 1, POD 3 and POD 5 were 16.0×10/L, 10.8×10/L and 8.7×10/L, respectively, which were all significantly higher than those in the other 2 groups (all P<0.05). No significant differences were obtained between other infection group and non-infection group in all these three markers (all P>0.05). ROC curve demonstrated that PCT had the biggest area under the curve (AUC) of 0.86 and 0.84 on POD 3 and POD 5, with the cut-off value of 0.98 μg/L and 0.83 μg/L, 92.0% sensitivity and 74.0% specificity, 91.0% sensitivity and 73.0% specificity, respectively. The highest AUC was 0.72 on POD 3 for CRP and 0.71 on POD 3 for WBC, with 80.0% sensitivity and 54.0% specificity, 56.0% sensitivity and 73.0% specificity, respectively.

CONCLUSIONThe value of procalcitonin above 0.98 μg/L on POD 3 and 0.83 μg/L on POD 5 can predict the occurrence of IAI after definitive operations of intestinal fistulae.

Over the past decades, the evolution of the techniques used in the intensive care has led on one side to better survival rates in ICU patients. On the other side, it has resulted in a growing number of patients who survive an acute event to chronic condition, and who then become dependent on one or more life support treatments. Such patients are called chronic critical illness(CCI) patients. Even these patients can dismiss from intensive care unit (ICU) or transfer to specialized rehabilitation care settings, the mortality of these patients is still very high. Therefore, how to promote the rehabilitation of CCI patients is one of the most important research points of epidemiology, public health and social economics. Exercise training can promote rehabilitation, improve quality of life and independent functional status in these patients, which should be used as one of the standard treatment protocols for CCI patients.

OBJECTIVE:To discuss the application of rational drug use software system in drug dispensing in outpatient depart-ment of our hospital. METHODS:The application of rational drug use software system (included clinical decision support soft-ware,drug dispensing software and drug management software) in prescribing (warning in advance),dispensing (intervention in the event)and the prescription review(the post review)in outpatient department of our hospital were all introduced. Outpatient pre-scription checking and intervention were collected from our hospital after the application of rational drug use software system to evaluate the effect of the software system. RESULTS & CONCLUSIONS:Rational drug use software system is adopted to realize scientific,convenient and express monitoring and management of prescription drug use in advance,in the course and afterwards. A total of 721 507 outpatient prescriptions were checked in our hospital from Jan. to May in 2015;0.17‰prescriptions were intercept-ed by system warning;system pointed out and pharmacists had checked 23.25% prescriptions;the rate of qualified prescription was more than 99.96%. After pharmacists intervention,various types of irrational prescriptions decreased significantly (P<0.01). It is suggested that pharmacists should make full use of information system,at the same time,optimize and improve the system through active exploration so as to improve rational drug use.
