OBJECTIVETo evaluate clinical therapeutic effect of post-stroke shoulder pain treated by acupuncture combined with Tuina.
METHODSThree hundred cases of post-stroke shoulder pain were randomly divided into an acupuncture and Tuina group and a rehabilitation group by double-center randomized controlled clinical trial method. In acupuncture and Tuina group, normalized electroacupuncture and Tuina therapy were applied, that was electroacupuncture at main points, such as Chize (LU 5), Quze (PC 3), Shaohai (HT 3), Jianyu (LI 15), Jianliao (TE 14) and Jianjing (GB 21),etc., combined with traditional Tuina manipulations; in rehabilitation group, the rehabilitation methods such as the electrostimulation through nervus cutaneus and the squeezing and stabilizing manipulations of Proprioceptive Neuromuscular Facilitation (PNF), etc. were applied. The treatment courses of both groups were 6 weeks. The main therapeutic effect indices were the Assessment Face Scale (AFS) for pain when shoulder was in passive motion and the Fugl-Meyer Motor Assessment for upper limbs active function; the secondary indices were the moditied Rankin Scale (mRS) and the clinical incidences of shoulder-hand syndrome of hemiplegia and shoulder joint subluxation of hemiplegia.
RESULTSAfter 6 weeks treatment and 12 weeks follow-up, AFS score, Fugl-Meyer motor assessment of upper limbs active function and mRS evaluation in acupuncture and Tuina group were more obviously improved than those in rehabilitation group (P < 0.05, P < 0.01). Although the clinical incidences of shoulder-hand syndrome of hemiplegia and shoulder joint subluxation of hemiplegia in acupuncture and Tuina group was equal to those in rehabilitation group [3.55% (5/141) vs 8.45% (12/142), 1.42% (2/141) vs 5.63% (8/142), both P > 0.05], the data indicated that there was a superiority tendency in acupuncture and Tuina group.
CONCLUSIONThe combined therapy of electroacupuncture and Tuina is a normative manipulation, and the therapeutic effect is satisfying for post-stroke shoulder pain, superior to that of comprehensive rehabilitation treatment.

AIMTo study the metabolites of penehyclidine hydrochloride (PH) raceme, a new anticholinerigic drug invented by the Institute of Pharmacology and Toxicology, Academy of Military Medical Sciences.
METHODSThree healthy rat urine samples were collected within 24 h after a single i.m. dose of PH raceme and PH-d5 [(5 + 5) mg.kg-1] simultaneously. The eight metabolites of PH raceme were identified by the methods of LC-MS/MS, GC-MS, FAB-MS and the stable isotope ion cluster. Mass spectrometry was operated in the positive mode for the method of LC-MS/MS.
RESULTSM1 and M1* were identified as the oxygenated products of PH in the cyclopentyl group; M2 and M2* were as the hydroxylated products of PH in the cyclopentyl group; M3 and M3* were as the oxygented and hydroxylated products of PH at the meta-position of cyclopentyl group; M4 and M4* were identified as the dihydroxylated metabolites of PH, the hydroxylated position were at the cyclopentyl group and quiniuclidinol ring of PH. Among them, M1 and M1*, M2 and M2*, M3 and M3*, M4 and M4* were the isomers of each other.
CONCLUSIONThese characteristics can be used for future structure elucidation in studies of the metabolites of PH optical isomers. The structure data of PH metabolites provide important information for the clinical use and for developing better anticholinerigic drug.

BACKGROUNDHydrothorax, as one of the common complications of malignant tumors, still cannot be sensitively detected in clinical practice, thus requiring a sensitive, specific method for diagnosis. The aim of this study was to analyze the correlation between levels of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) in patients with benign and malignant hydrothorax.
METHODSThe contents of VEGF in the pleural effusion and serum of the patients with malignant pleural effusion (n = 35) and benign pleural effusion (n = 30) were detected by double antibody sandwich enzyme linked immunosorbent assay. The gene copy number level of EGFR in pleural effusion was detected by fluorescence in situ hybridization (FISH). The points with the highest sensitivity and specificity were selected as the critical values to calculate the diagnostic value of the VEGF in pleural effusion and serum, and EGFR gene copy number in pleural effusion.
RESULTSThe contents of VEGF in pleural effusion and serum of patients with malignant hydrothorax were (384.91 ± 120.18), and (129.62 ± 46.35) ng/L, respectively, which were significantly higher than those of the patients with benign hydrothorax (207.97 ± 64.04), (63.49 ± 24.58) ng/L (P < 0.01). The sensitivity and specificity of detecting VEGF in pleural effusion were 80.0% and 96.7% (the boundary value was 297.06 ng/L), respectively for diagnosing benign and malignant hydrothorax. The sensitivity and specificity of serum were 74.3% and 96.7%, respectively (the boundary value was 99.21 ng/L) for diagnosing benign and malignant hydrothorax. The diagnostic efficiencies of EGFR and VEGF in hydrothorax were similar. There was a significant correlation between EGFR and VEGF in hydrothorax (P < 0.01).
CONCLUSIONSVEGF and EGFR play important roles in the formation of pleural effusion. VEGF differed significantly in benign and malignant pleural effusions, which contributed to differential diagnosis results of benign and malignant pleural effusions. It is feasible to detect the gene copy number of the pleural effusion cell mass EGFR by FISH technique. Joint detection can improve the diagnostic sensitivity.

OBJECTIVES:
To study the clinical value of extracorporeal membrane oxygenation (ECMO) in the treatment of persistent pulmonary hypertension of the newborn (PPHN).
METHODS:
A retrospective analysis was performed on the medical data of 11 neonates with PPHN who were treated with ECMO in the Neonatal Intensive Care Unit of Zhongshan People's Hospital from January 2015 to December 2021, involving the neonates' general information, clinical diagnosis, laboratory results, duration of ECMO treatment, complications during ECMO treatment, length of hospital stay, and outcome.
RESULTS:
Of the 11 neonates, 10 (91%) had successful weaning from ECMO, and 8 (73%) survived. For the 11 neonates, the mean duration of ECMO treatment was (81±50) hours (range: 26 to 185 hours), the mean duration of ventilator use was (198±105) hours (range: 57 to 392 hours), and the mean length of hospital stay was (22±15) days (range: 2 to 49 days). The oxygenation index and blood lactate level were significantly improved after 24 hours of ECMO treatment among the 11 neonates (P<0.05). Ten neonates had significantly reduced pulmonary artery pressure after 24 hours of ECMO treatment (P<0.05). One neonate had a progressive increase in the pulmonary artery pressure during EMCO treatment, succumbing to death. This neonate was diagnosed with alveolar capillary dysplasia based on the histopathological findings of the lung tissue and whole-exome sequencing results. Among the 11 children, 5 had intracranial hemorrhage, 1 had disseminated intravascular coagulation, 1 had gastric hemorrhage, 2 had pulmonary hemorrhage, 1 had renal insufficiency, and 3 had bleeding at the puncture site during ECMO treatment.
CONCLUSIONS
ECMO is effective for the treatment of PPHN, however, the high incidence of complications of ECMO treatment suggests that it is important to carefully assess the indications and timing of ECMO treatment and improve the management of ECMO, which can improve the weaning rate and survival rate.
