Objective:To investigate the regression of regional lymph nodes after administering neoadjuvant short-course chemoradiother-apy combined with immunotherapy in patients with locally advanced rectal cancer(LARC).Methods:This retrospective study analyzed the clinical data of 40 patients with LARC admitted to Zhongshan Hospital Affiliated to Xiamen University(32 cases)and the Union Hospital,Tongji Medical College,Huazhong University of Science and Technology(8 cases)between January 2021 and December 2022.The control and experimental groups consisted of 20 patients who underwent direct laparoscopic surgery and neoadjuvant short-course chemoradio-therapy combined with immunotherapy prior to the laparoscopic surgery,respectively.The detection of the postoperative lymph node was compared between the two groups.In addition,the pathologic complete response(pCR)rate of the primary tumor and regional lymph nodes in the experimental group was assessed.Results:The number of patients with N downstaging(18 vs.7,P<0.001)significantly in-creased,whereas the positive lymph node metastasis rate(1.4%vs.19.1%,P<0.001)and number of patients with positive lymph nodes(4 vs.16,P<0.001)significantly decreased in the experimental group compared to those in the control group.Although the number of detected lymph nodes in the experimental group was slightly lower compared to that in the control group(18.3±8.7 vs.20.4±6.5,P=0.392),it was not statistically different.Furthermore,the pCR rate of the regional lymph nodes was significantly higher than that of the primary tumor in the experimental group(80%vs.30%,P=0.001).Conclusions:Neoadjuvant short-course chemoradiotherapy combined with immunotherapy caused significant pathological remission of positive lymph nodes in patients with LARC.This study hypothesizes that a"spatial effect"con-tributes to the pathological remission of regional lymph nodes in rectal tumors.

Chronic pain can develop from acute pain, and it is not only difficult to cure, but also easy to develop secondary psychological problems and negative emotions such as anxiety and depression, and the hippocampal plays a vital role in chronic pain. The morphological and functional changes in the hippocampus mediate the development and maintenance of chronic pain. This review focuses on the role of hippocampal abnormalities in chronic pain in recent years, in order to provide new ideas for the treatments of chronic pain and related dysthymic disorder complications in the future.

Since January 2020, as ophthalmologists working at the center of the novel coronavirus pneumonia (NCP) outbreak in Wuhan, China, we found 3 cases in 30 NCP patients with binocular conjunctivitis. Of them, one case visited for conjunctivitis as a first symptom and then diagnosed as NCP, and two cases visited for binocular conjunctivitis during the NCP onset. In 3 patients, conjunctivitis was manifested as signs of viral conjunctivitis from mild to moderate. Their symptoms of two patients disappeared after treatment with antiviral eyedrops for 7 to 10 days and another patient died of NCP. Interestingly,although we detected positive viral nucleic acid in the conjunctiva sacs of 2 of other 27 NCP patients by using swabs and RT-PCR technology, no conjunctivitis occurred in these two patients.

Plasticity related gene(PRG) is a subclass of the lipid phosphate phosphatase super family, which is predominantly expressed in the central nervous system in a subtype specific pattern. PRG may be involved in mechanism of nervous system functions and pathogenesis of neuropsychiatric diseases via neuron-specific transcriptional regulation, protein-protein interaction and intracellular signaling pathway regulation. Therefore, this paper reviews the progresses of PRG in recent years and prospects the future research direction.

Objective To explore the protective measure and the complication of laparoscopic common bile duct primary closure surgery with self-releasing single-J tube. Methods The clinical data of 35 choledocholithiasis patients having underwent selective operation were retrospectively analyzed from January 2009 to November 2014. The operation was laparoscopic choledocholithotomy, a self-releasing single J-tube was placed in the common bile duct, and the common bile duct was primary closure. The postoperative complication was observed. Results All the patients were operated under laparoscope. The operative time was (120 ± 15) min, and the intraoperative bleeding was (50 ± 15) ml. The levels of diastase was normal or increased slightly 1 d after operation. There were no postoperative bile leakage, bleeding and incision infection. The diet was recovered 2-4 d after operation. Postoperative abdominal X-ray result showed that single-J tube position was good. Two-three weeks after operation, the single-J tube was discharged from the intestinal tract, without intestinal obstruction. The length of stay was (9.3 ± 1.8) d. Open operation with T tube drainage was performed in one case with the complication of stone residue and stenosis of common bile duct. Conclusions In laparoscopic common bile duct primary closure surgery, self-releasing single-J tube can provide security guarantees in patients with choledocholithiasis. Although there are some complications, it has less trauma and quicker recovery, and deserves further popularization and application.

Objective To study the effect of postoperative anticoagulant therapy after splenectomy in patients with cirrhosis and portal hypertension.Methods One hundred and forty patients with cirrhosis and portal hypertension receiving splenectomy and periesophagastric devascularization were divided into anticoagulant group (76 cases) and control group (64 cases) by random number table,patients in anticoagulant group received postoperative anticoagulant therapy,principally according to the platelet count,gave ligustrazine,aspirin,low molecular heparin after operation; patients in control group without postoperative anticoagulant therapy.Postoperative monitoring platelet count and D-dimer,ultrasound or CT check the presence of portal vein thrombosis.Results Platelet count,D-dimer levels in anticoagulant group and control group in 2 days after operation were significantly increased,the difference was significant compared with preoperative [anticoagulant group:(95.73 ± 28.06) × 109/L vs.(38.41 ± 11.96) × 109/L,(3.61 ± 0.18) mg/L vs.(0.42 ± 0.09) mg/L;control group:(92.56 ± 27.75) × 109/L vs.(35.13 ± 11.38) × 109/L,(3.26 ± 0.16) mg/L vs.(0.37 ± 0.09) mg/L,P ＜ 0.05].Platelet count and D-dimer levels between two groups at preoperative and postoperative in 2 days had no statistical significance (P ＞ 0.05).Ten cases of control group occurred postoperative portal vein thrombosis,anticoagulant group were 3 cases,portal vein thrombosis incidence of anticoagulant group [3.95％ (3/76)] compared with control group [15.62％(10/64)] was statistically significant (P ＜ 0.05).Conclusion Postoperative anticoagulant therapy after splenectomy in patients with cirrhosis and portal hypertension is an effective method to prevent portal vein thrombosis.

This paper is to report the investigation on the metabolic behavior of Staphylococcus aureus (S. aureus) after given Qingkailing injection, and with the aim of seeking for a new quality control method based on biological assessment. The growth thermogenic curves of S. aureus were determined by microcalorimetry and analyzed by computer. The results showed that in the concentration range of (0-5.00%), the growth thermogenic curves of S. aureus were declined and removed back with increasing dosage of Qingkailing injection; the main parameters (T1, T2, k1, P1, P2 and I) and the dosage of Qingkailing injection have good correlation. The 50% inhibiting dosage is 3.26 %, and the optimal inhibiting dosage is 5.47%. Difference could be detected among the Qingkailing injection samples from different factories and different batches. It is proved that Qingkailing injection could inhibit the metabolic behavior of S. aureus, and microcalorimetry might be applied in the quality assessment of Qingkailing injection.

The inhibitory ratio (1%) of artificial musk on cyclooxygenase-2 (COX-2) was determined by enzyme immunoassay (EIA). The dose-effect relationship between concentrations of artificial musk and 1% was established. It was found that artificial musk had obvious inhibitory action on COX-2. The concentration for 50% of maximum inhibitory effect (IC50) was about 2.26 mg x mL(-1). There was a good relationship between the logarithm concentrations of artificial musk and 1% when the concentrations of artificial musk ranged from 0.31-20.0 mg x mL(-1). The results indicated that this EIA method could be applied to evaluate the anti-inflammatory activity of artificial musk quickly, conveniently, sensitively and exactly. This paper provided a novel method and foundational research for the bioassay of artificial musk.
