Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

OBJECTIVE: To compare the efficacy and safety of intravenous colistin sulfate combined with nebulized inhalation versus intravenous monotherapy for pulmonary infections caused by carbapenem-resistant organism (CRO). METHODS: A multicenter retrospective cohort study was conducted. Clinical data were collected from patients admitted to the intensive care unit (ICU) of 10 tertiary class-A hospitals in Henan Province between July 2021 and May 2023, who received colistin sulfate for CRO pulmonary infections. Data included baseline characteristics, inflammatory markers [white blood cell count (WBC), neutrophil count (NEU), procalcitonin (PCT), C-reactive protein (CRP)], renal function indicators [serum creatinine (SCr), blood urea nitrogen (BUN)], life support measures, anti-infection regimens, clinical efficacy, microbiological clearance rate, and prognostic outcomes. Patients were divided into two groups: intravenous group (colistin sulfate monotherapy via intravenous infusion) and combination group ((intravenous infusion combined with nebulized inhalation of colistin sulfate). Changes in parameters before and after treatment were analyzed. RESULTS: A total of 137 patients with CRO pulmonary infections were enrolled, including 89 in the intravenous group and 48 in the combination group. Baseline characteristics, life support measures, daily colistin dose, and combination regimens (most commonly colistin sulfate plus carbapenems in both groups) showed no significant differences between two groups. The combination group exhibited higher clinical efficacy [77.1% (37/48) vs. 59.6% (52/89)] and microbiological clearance rate [60.4% (29/48) vs. 39.3% (35/89)], both P < 0.05. Pre-treatment inflammatory and renal parameters showed no significant differences between two groups. Post-treatment, the combination group showed significantly lower WBC and CRP [WBC (×10⁹/L): 8.2±0.5 vs. 10.9±0.6, CRP (mg/L): 14.0 (5.7, 26.6) vs. 52.1 (24.4, 109.6), both P < 0.05], whereas NEU, PCT, SCr, and BUN levels showed no significant between two groups. ICU length of stay was shorter in the combination group [days: 16 (10, 25) vs. 21 (14, 29), P < 0.05], although mechanical ventilation duration and total hospitalization showed no significant differences between two groups. CONCLUSIONS Intravenous colistin sulfate combined with nebulized inhalation improved clinical efficacy and microbiological clearance in CRO pulmonary infections with an acceptable safety profile.

Objective:To research the efficacy and safety of robotic thyroidectomy and bilateral modified radical neck dissection through bilateral axillo-breast approach (BABA) .Methods:We retrospectively analyzed the clinical data of 37 patients with thyroid cancer who received bilateral modified radical neck dissection through the BABA at the Department of Thyroid and Breast Surgery of the 960th Hospital of the People’s Liberation Army from Jan. 2014 to Jan. 2023. There were 24 females and 13 males, and the average age of the patients was (33,22±10.53) years old. The tumor diameter, number of lymph node dissection and metastasis in the central and lateral regions, average operation time, average hospital stay, complications, and aesthetic score were recorded. SPSS 25.0 software was used for statistical analysis, and the measurement data was calculated using mean ± standard deviation ( ± s), and the counting data was expressed in percentages and numbers. Results:A total of 37 thyroid cancer patients underwent robotic bilateral regional lymph node dissection. The 37 patients received total thyroidectomy, bilateral central compartment and cervical lateral regional lymph node dissection. All the pathological types were papillary carcinoma, with a maximal tumor diameter of (1.47±0.85) cm. The average number of central lymph nodes dissected was 19.46±8.84, and there were (10.24±5.95) metastases; The average number of lymph nodes removed from the bilateral cervical region was 38.92±14.21, and there were (7.92±5.84) metastases. The average operation time was (288.05±77.09) min, the average length of stay in the hospital was (10.76±3.92) days, and the average length of stay in the hospital following surgery was (8.03±2.08) days. These patients had no permanent hypoparathyroidism, permanent recurrent laryngeal nerve palsy, infection, accessory nerve injury and phrenic nerve injury after operation. Transient hypoparathyroidism occurred in 15 patients, transient recurrent laryngeal nerve palsy occurred in 1 patient, and chyle leak occurred in 2 patients. One month after surgery, the aesthetic score was 9.51±0.69.Two patients were found lymph node metastases during the (27.81±15.10) months of follow-up, and received robotic cervical lymph node dissection with BABA.Conclusion:For carefully chosen thyroid cancer patients with bilateral lateral cervical region lymph node metastases, robotic bilateral cervical lymph node regional dissection via BABA is safe and feasible, and good cosmetic results can be obtained.

This paper summarized Professor PENG Peichu's experience in the differentiation and treatment of prostate cancer in three phases and four stages. It is considered that prostatic cancer is categorized into root deficiency and branch excess， with depletion of healthy qi as the root， and the accumulation of cancer toxin as the minifestation. Clinical diagnosis and treatment of prostatic cancer can be divided into three phases and four stages according to the exuberance and decline of pathogenic and healthy qi and the changes of deficiency and excess of yin and yang. In the initial accumulation phase of cancer toxin （yang excess stage）， the key pathogenesis is the accumulation of dampness， heat and static blood， and internal generation of cancer toxin， and the treatment should be resolving toxins， fighting cancer and dispelling yang excess. In the phase of healthy qi deficiency and toxin accumulation （yin deficiency stage）， with the lung and kidney yin deficiency， dampness， heat and static toxin accumulation as the key pathogenesis， the treatment should be centered on mutual generation between metal and water to nourish kidney yin， supplemented with the method of clearing heat and draining dampness， activating blood and resolving toxins， for which self-made Nanbei Formula（南北方）is usually used. In the phase of yang deficiency and cold stagnation （yang deficiency stage and yin excess stage）， with the spleen and kidney yang deficiency， cold dampness stagnation， static heat and toxin accumulation as the key pathogenesis， the treatment should be warming and tonifying spleen and kidney to dissipate cold accumulation； for deficiency of both yin and yang， and excess pathogen obstruction， modified Yanghe Decoction（阳和汤） is recommended， while for yang deficiency， cold congealing and blood stasis， self-made Wenshen Sanjie Formula（温肾散结方） can be used， and for cold dampness binding with cancer toxin， and cold complex with heat， self-made Quanan Formula （泉安方） is advised.

Objective:This study aimed to share preliminary experiences of single-incision plus two ports laparoscopic proximal gastrectomy with right-sided overlap and single-flap valvuloplasty (ROSF).Methods:Following the 6th edition of the Japanese Gastric Cancer Treatment Guidelines, proximal gastrectomy with lymphadenectomy was performed. Using a single-port approach, the esophagus was transected at least 2 cm above the tumor's upper margin with linear staplers. The stomach was then extracted through a periumbilical incision, and the proximal stomach was subsequently transected extracorporeally, while ensuring appropriate resection margins on both the greater and lesser curvatures. A single flap was created before returning the remnant stomach to the abdominal cavity and re-establishing pneumoperitoneum. The No.2 clip was used to grasp and elevate the esophageal stump. An incision was made at the right lower edge of the esophageal stump to guarantee that the esophageal lumen was open. The linear stapler was then inserted into the openings of the stomach and esophagus to perform a side overlap anastomosis with a length of 3 cm. Another barbed suture was used to close the common opening of the esophagus and the stomach, and the same barbed suture were used to suture the gastric wall to the lower edge of the muscle flap. The first barbed suture was then used to sequentially suture the proximal brim of the flap to the esophagus and the right brim of the flap to the right brim of the mucosal window. After completion of anastomosis, a drainage tube was inserted through the right upper port. This procedure was employed from November 2023 to March 2024 on five patients diagnosed with adenocarcinoma of the esophagogastric junction and upper stomach. The cohort consisted of three males and two females, with an age range of 62 to 75 years and a body mass index (BMI) of 13.7 to 24.2 kg/m2. All cases were preoperatively staged as T1-2N0M0, confirmed by endoscopic biopsy and enhanced CT scans of the chest, abdomen, and pelvis.Results:All five patients successfully underwent the surgery. The median surgery time was 180-325 minutes, with the intraoperative blood loss of 30-50 ml. The number of lymph nodes harvested ranged from 18 to 27. The time to first flatus, and restore liquid diet and was 2.0-5.0 and 1.0-3.0 days, respectively. The postoperative length of stay was 9.0-11.0 days. The pain scores on the Numeric Rating Scale (NRS). On the first day, the pain scores were 3.0 in two cases, 2.0 in two cases, and 1.0 in one case. On the second day, the pain scores were 2.0 in two cases and 1.0 in three cases. On the third day, the pain scores were 1.0 in four cases and 2.0 in one case. No short-term postoperative complications were observed, and there were no perioperative deaths.Conclusion:Single-incision plus two ports laparoscopic proximal gastrectomy with ROSF is safe and feasible.

Objective This study aimed to investigate the effects of silencing Ras homolog family member C(RhoC)on the proliferation,apoptosis,invasion,migration,and epithelial-mesenchymal transition(EMT)of salivary adenoid cystic carcinoma(SACC)and its molecular mechanisms.Methods A total of 27 SACC lesions and normal salivary gland tissues that were surgically resected at Qingdao Municipal Hospital from January 1,2019 to March 1,2024 were selected,and the expression levels of RhoC were detected by Western blot and immunohistochemistry.Three small interfering RNA(siRNAs)were designed to target the RhoC gene sequence,transfected into SACC-LM and SACC-83 cell lines,and evaluated for transfection efficiency.The protein expression levels of RhoC,Rho-asso-ciated protein kinase-1(ROCK1),p38 mitogen-activated protein kinase(p38MAPK),phosphorylated-p38MAPK(p-p38MAPK),twist family bHLH transcription factor 1(TWIST1),E-cadherin,N-cadherin,and Vimentin were com-pared using Western blot.CCK-8 assay,flow cytometry,transwell invasion assay,and wound healing assay were conducted to assess the differences in cell proliferation,apoptosis,invasion,and migration abilities among the groups.Bioinformatics methods were also used to predict possible upstream micro RNAs(miRNAs)of RhoC and their expression levels in SACC.Moreover,dual-luciferase reporter gene experiments were performed to verify the binding sites of miR-138-5p and RhoC.Results RhoC was highly expressed in SACC(P＜0.05).After silencing RhoC,the test group showed a significant decrease in the expression level of ROCK1,p-p38MAPK,TWIST1,N-cadherin,and Vimentin,as well as a significant increase in the expression level of E-cadherin(P＜0.05).No signifi-cant difference in the expression level of p38MAPK was observed(P＞0.05).The cell proliferation,invasion,and mi-gration ability decreased in the test group,whereas the apoptosis rates significantly increased(P＜0.05).miR-138-5p was lowly expressed in SACC,and miR-138-5p mimic can significantly downregulated the luciferase activity of 293T cells after transfection with a RhoC wild-type plasmid(P＜0.05).Conclusion RhoC is highly expressed in SACC,and RhoC silencing may target the downstream ROCK1/p38MAPK/TWISTl signaling pathway,thereby in-hibiting the proliferation,invasion,migration,and EMT of SACC while promoting its apoptosis.On the contrary,miR-138-5p is lowly expressed in SACC and is a potential upstream gene of RhoC,and there may be binding sites between the two genes.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To study the reversal effect of NVP-BEZ235 on doxorubicin resistance in Burkitt lymphoma RAJI cell line.Methods:The doxorubicin-resistant cell line was induced by treating RAJI cells with a concentration gradient of doxorubicin.The levels of Pgp,p-AKT,and p-mTOR in cells were detected by Western blot.Cell viability was detected by MTT assay.IC50 was computed by SPSS.Results:The doxorubicin-resistant Burkitt lymphoma cell line,RAJI/DOX,was established successfully.The expression of Pgp and the phosphorylation levels of AKT and mTOR in RAJI/DOX cell line were both higher than those in RAJI cell line.NVP-BEZ235 downregulated the phosphorylation levels of AKT and mTOR in RAJI/DOX cell line.NVP-BEZ235 inhibited the proliferation of RAJI/DOX cell line,and the effect was obvious when it was cooperated with doxorubicin.Conclusion:The constitutive activation of PI3K/AKT/mTOR pathway of RAJI/DOX cell line was more serious than RAJI cell line.NVP-BEZ235 reversed doxorubicin resistance of RAJI/DOX cell line by inhibiting the PI3K/AKT/mTOR signal pathway.
