Objective We aimed to investigate the symptoms of inpatients with bipolar disorder (BD) in different types of families, and to explore the correlations between family coherence, family adaptability, and family functioning among inpatients with BD. Methods Inpatients with BD in Hebei, China (n = 61; mean age = 33.85±10.54; 39 males) participated in this study. Participants’ symptoms were evaluated using the Bech–Rafaelsen Mania Scale (BRMS) and Hamilton Depression Rating Scale (HDRS) at weeks 1, 4, and 8 after their admission to the hospital. Participants’ family type was assessed using the Family Adaptability and Cohesion Scale II–Chinese Version. Family functioning was assessed using Family Assessment Device. Results Participants were classified into three family types: balanced (n = 13), mid-range (n = 28), and extreme (n = 20). BRMS scores improved over time in patients from all three family types. Improvement was slightly better with the balanced than the extreme family type. HDRS scores showed an improving trend over time, although this was not significant. Family coherence, adaptability, and functioning were mutually correlated. Conclusion The family system and family functioning are important factors that clinicians should keep in mind when treating people with BD.

An all-solid-state single-frequency 1064 nm laser with a 100 µs pulse width, 500 Hz repetition rate and 700 mJ single pulse energy is designed using seed injection and a three-stage master oscillator power amplifier (MOPA) construction. Using this as a basis, research on long-pulse laser frequency doubling is carried out. By designing and optimizing the lithium triborate (LBO) crystal, the theoretically calculated maximum conversion efficiency η max reaches 68% at M 2 = 1, while η min is 33% at M 2 = 3. Generation of 212 mJ pulses of green light with a repetition rate as high as 500 Hz is obtained from a fundamental energy of 700 mJ. The experimental conversion efficiency reaches 31% and the power stability is better than ±1%.
